Vous souhaitez ajouter les métadonnées de Facebook Open Graph à vos thèmes WordPress ?
Les métadonnées Open Graph aident Facebook et d’autres sites de réseaux sociaux à obtenir des informations sur vos publications et pages WordPress. Elles vous permettent également de contrôler la façon dont votre contenu apparaît lorsqu’il est partagé sur Facebook.
Dans cet article, nous allons vous afficher comment ajouter facilement les métadonnées de Facebook Open Graph dans les thèmes WordPress.
Nous allons partager trois méthodes différentes afin que vous puissiez choisir celle qui fonctionne le mieux pour votre site WordPress:
Méthode 1 : Ajout des métadonnées Open Graph de Facebook avec AIOSEO
All in One SEO est une extension WordPress SEO populaire utilisée par plus de 3 millions de sites. Il vous permet d’optimiser facilement votre site pour les moteurs de recherche ainsi que pour les plateformes sociales comme Facebook et Twitter.
Tout d’abord, vous devez installer et activer l’extension gratuite All in One SEO. Pour plus de détails, consultez notre guide étape par étape sur l’installation d’une extension WordPress.
Une fois activé, vous devez vous rendre sur la page All in One SEO » Réseaux sociaux. Ici, vous pouvez saisir l’URL de votre page Facebook et de tous vos autres réseaux sociaux.
Ensuite, cliquez sur l’onglet Facebook en haut de la page, et vous verrez que le balisage Open Graph est activé par défaut.
Vous pouvez cliquer sur le bouton » Téléverser ou sélectionner une image » pour choisir une image Facebook OG par défaut si un article n’a pas d’image Open Graph.
Si vous défilez vers le bas, vous pouvez personnaliser le nom de votre site, sa description et d’autres réglages. N’oubliez pas de cliquer sur le bouton bleu « Enregistrer les modifications » lorsque vous avez terminé.
Maintenant que vous avez défini des métatags Open Graph à l’échelle du site, l’étape suivante consiste à ajouter des métadonnées Open Graph pour les publications et les pages individuelles.
Par défaut, AIOSEO utilisera le titre et la description de votre publication pour le titre et la description de l’Open Graph. Vous pouvez également définir manuellement la miniature Facebook pour chaque page et publication.
Il vous suffit de modifier la publication ou la page et de défiler jusqu’à la section » Réglages AIOSEO » située sous l’éditeur. À partir de là, passez à l’onglet Social, et vous verrez une prévisualisation de votre miniature.
Vous pouvez définir ici l’image du réseau social, ainsi que le titre et la description.
Défilez simplement vers le bas jusqu’au champ « Source de l’image ». Vous pouvez choisir d’utiliser l’image mise en avant, de téléverser une image personnalisée ou d’autres options.
Réglages 2 : Définir les métadonnées Open Graph de Facebook avec Yoast SEO
Yoast SEO est une autre extension WordPress SEO que vous pouvez utiliser pour ajouter les métadonnées Open Graph de Facebook à n’importe quel site WordPress.
La première chose à faire est d’installer et d’activer l’extension Yoast SEO. Pour plus de détails, consultez notre guide étape par étape sur l’installation d’une extension WordPress.
Une fois activé, vous devez vous rendre dans SEO » Social et sélectionner l’option » Activé » sous » Ajouter des métadonnées Open Graph « .
Vous pouvez enregistrer vos réglages ou continuer et configurer d’autres facultés sociales de Facebook.
Vous pouvez fournir un ID d’application Facebook si vous en utilisez un pour votre page Facebook et vos insights. Vous pouvez également modifier le méta titre, la méta description et l’image de votre page d’accueil Open Graph.
Dernier point, vous pouvez définir une image par défaut qui sera utilisée lorsqu’aucune image n’est définie pour une publication ou une page.
Yoast SEO vous permet également de définir les métadonnées Open Graph pour les publications et les pages individuelles. Il suffit de modifier un article ou une page et de défiler jusqu’à la section » Yoast SEO » située sous l’éditeur.
À partir de là, vous pouvez définir une miniature Facebook pour cette publication ou page particulière. Si vous ne définissez pas de titre ou de description pour la publication, l’extension utilisera votre méta titre et votre méta description SEO.
Vous pouvez maintenant enregistrer votre publication ou votre page, et l’extension stockera vos métadonnées Open Graph de Facebook.
Méthode 3 : Ajout des métadonnées Open Graph de Facebook à l’aide d’un code
Cette méthode nécessite de modifier les fichiers de votre thème, assurez-vous donc d’effectuer une sauvegarde de vos fichiers de thème avant de procéder à des modifications.
Ensuite, il suffit de copier et de coller ce code dans le fichier functions.php de votre thème ou d’ajouter l’extrait de code à l’aide de l’extension WPCode (recommandé).
Tout d’abord, installez et activez l’extension gratuite WPCode. Pour plus de détails, veuillez consulter notre guide sur l ‘installation d’une extension WordPress.
Une fois activé, vous pouvez vous rendre dans » Code Snippets » + » Add Snippet « à partir de votre Tableau de bord WordPress. Vous devez survoler le premier extrait libellé » Ajouter votre code personnalisé (nouvel extrait) » et cliquer sur le bouton » Utiliser l’extrait « .
Cela créera un nouvel extrait de code dans lequel vous devrez saisir un titre et sélectionner le type de code « PHP Snippet ». Ensuite, vous devez publier le code suivant dans la section « Prévisualisation du code » :
//Adding the Open Graph in the Language Attributes
function add_opengraph_doctype( $output ) {
return $output . ' xmlns:og="http://opengraphprotocol.org/schema/" xmlns:fb="http://www.facebook.com/2008/fbml"';
}
add_filter('language_attributes', 'add_opengraph_doctype');
//Lets add Open Graph Meta Info
function insert_fb_in_head() {
global $post;
if ( !is_singular()) //if it is not a post or a page
return;
echo '<meta property="fb:app_id" content="Your Facebook App ID" />';
echo '<meta property="og:title" content="' . get_the_title() . '"/>';
echo '<meta property="og:type" content="article"/>';
echo '<meta property="og:url" content="' . get_permalink() . '"/>';
echo '<meta property="og:site_name" content="Your Site Name Goes Here"/>';
if(!has_post_thumbnail( $post->ID )) { //the post does not have featured image, use a default image
$default_image="http://example.com/image.jpg"; //replace this with a default image on your server or an image in your media library
echo '<meta property="og:image" content="' . $default_image . '"/>';
}
else{
$thumbnail_src = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), 'medium' );
echo '<meta property="og:image" content="' . esc_attr( $thumbnail_src[0] ) . '"/>';
}
echo "
";
}
add_action( 'wp_head', 'insert_fb_in_head', 5 );
N’oubliez pas d’ajouter le nom de votre site à la ligne 17, à l’endroit où il est indiqué « Your Site Name Goes Here ». Ensuite, vous devez modifier l’URL de l’image par défaut à la ligne 19 avec l’une de vos propres URL d’image.
Nous vous recommandons d’y placer une image avec votre logo, de sorte que si votre publication n’a pas de miniature, elle tire le logo de votre site.
Vous devez également ajouter votre propre ID d’application Facebook à la ligne 13. Si vous n’avez pas d’application Facebook, vous pouvez retirer la ligne 13 du code.
Une fois que vous avez terminé la mise à jour du code, vous devez permuter l’extrait de code sur » Actif » et cliquer sur le bouton » Enregistrer l’extrait « . Votre thème va maintenant commencer à afficher les métadonnées de Facebook Open Graph dans l’en-tête de WordPress.

Did you set a featured image? did you replace the default image URL in the code with your own image URL?
Ikix says
Hello, I’ve tried everything i could an i can’t display thumbnail image when i post my blog url on facebook, i already add the code as you said, i download tons of plugings and there is no image in facebook! can you help me please? pleeease!
Jason C. says
what about just for a single image to be added to the thumbnail options in Facebook? I’ve noticed it picks up my featured image no problem, but doesn’t pick up the others in the post. Is there a way to manually add them with some quick code?
WPBeginner Staff says
Sorry the plugin is no longer available. We have updated the article, with new information. Hope this will help you add Facebook Open Graph Meta Data into your WordPress. site.
adepush says
Hi, is your plugin still available on WordPress.org?

its still pulling the image from the sidebar instead of the image i have put in the functions file?
damian says
What about og:description?
Musadiq says
Hi,
How can I include a facebook in the code above? So it can directly publish an article to our profile timeline and also to our facebook page. Thank you
Hassan says
its not working for me when i share my posts on face book its only shows my last instagram pics
Loes Liemburg says
Hi, I installed this plug-in, but can’t see the OG-options in my settings menu. I’ve refreshed and waited, but still nothing. What has gone wrong?
Manuel Gomez says
This line means that the image will use the medium size?
$thumbnail_src = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), ‘medium’ );
If i replace for « big » will use the big image? i would like to see the link post with the new format in facebook, because i can get more clics.
Thanks!
Alexandra says
Thank you! the code worked perfectly!
M says
Unfortunately this did not work for me, I can’t even see it being output in the WP head source code. I’m using the code method as I don’t want to add any plugins to the site.
I’ve checked the htaccess file and that is not causing any issues since it’s blank except for the perma link declaration.
Its also not a caching plugin either since I dont have one in place. Any ideas?
M says
Actually sorry this did work, but unfortunately using the debugger tool it still seems that posting a link on my timeline still does not show the og:image.
Even if it’s there in the json. Its really bizarre. The debugger shows the post but without any image in the share preview. Any ideas anyone?
Attila says
Hello Syed,
I have use many plugins to extract my graph meta info since I’ve started to use WordPress and Facebook and I can say that « Facebook Open Graph Meta for WordPress » is the most simple yet professional plugin so far.
I have a minor issue tough…when debugging my posts link with the the Facebook debugger, my Raw Open Graph Document Information does not show up properly. I have special characters included as my content is in Hungarian language.
Here is an example:
Meta Tag:
I would appreciate if someone could tell me how to fix this.
Thanks in advance and keep up the good work.
Best Regards
JessDelAngel says
HI!
Did you find a solution for this?
Regards
Jim says
Works well – thanks. This is still the best way to integrate without a plugin, yes?
Editorial Staff says
We are using WordPress SEO by Yoast plugin to do this.

ally says
I’ve been using this code for a long time but recently there’s been problems, it doesn’t always pull the image. I used the linter and found this errror:
Inferred Property The ‘og:description’ property should be explicitly provided, even if a value can be inferred from other tags.
So I added the description tag and that seems to have resolved the image issue but now it no longer displays the article content.
Any idea’s how to resolve this? I just need to show the first few lines of content.
Thanks
Editorial Staff says
Just use Yoast’s SEO plugin and it has this built-in.
Administrateur
Goob says
Yoast’s SEO Plugin doesn’t seem to have single page og:descriptions built-in.
Editorial Staff says
Yes it does have it built-in. By default it pulls your meta description, but it also has the option for you to modify the description from the Yoast SEO meta box.
Theo says
Hi there,
I was just wondering whether it is possible to have a different « og:type » for a post and a page. As it stands (well from what I understand) is that for everything in WordPress, this sets the « og:type » to article.
What if I want to set « og:type » of page to say « website » and for a post « article »?
Any suggestions or help much appreciated
Thanks
Editorial Staff says
You most certainly can with conditional statements.
Administrateur
Editorial Staff says
You have to attach the post thumbnail using the featured image function.

seitanist says
Can someone explain why
global $post;
is needed and where it falls in the generated code?
wpbeginner says
@seitanist Yes the reason why global $post is added because this code is being added outside the Loop in the section of the page. In order to pull the right information, we must call global $post which makes all those tags work.
seitanist says
This worked great! Thanks!!!
Editorial Staff says
You can try disabling the social feature in Yoast’s plugin and download Otto’s Simple Facebook Connect plugin. Just activate it and the base would take care of it.

Cno says
Hello, everything worked! When i put the link of my specific blog post on my facebook wall, I have the right thumbnail, description and site name. But the post on facebook also automatically shows the complete url of my site (right under the blog title). Instead I want it to show the permalink of the specific blog post – not the url of my site. This way i can integrate the ‘likes’ for that particular post in wordpress. Please! Anyone?
StephanePerez says
Hi, i tried to insall the plugin but can’t activate it because of a fatal error : Cannot redeclare add_opengraph_doctype()…/fbogmeta.php on line 24
What i’m supposed to do?
Thanks!
techhogger says
Hi pasted this codes as per the instruction on my blog techhogger.com but still issue does not seem to resolve. I can see my adsense codes in the description area. Kindly help.
waqaslone says
@techhogger same problem with…let me know if u find any solution.
wpbeginner says
@waqaslone@techhogger For the description to appear, you have to use the excerpts. Alternatively, you can use Otto’s Simple Facebook Connect plugin and just turn the Base on. That would take care of everything for you.
techhogger says
@wpbeginner@waqaslone@techhogger
I did everything. Even tried the plugin you said. Just try to share any post from my blog and you will know what exactly is happening. To some extend I was able to remove codes appearing from the description section. But now I can’t see description and thumbails of the post while sharing it on fb. Will be thankful if I get your help.
wpbeginner says
@techhogger@waqaslone We are using the method shared on this page on our own website. Everything works. We are using SFC on List25 and it works perfectly fine. Not sure why you are having these issues. SFC has a very smart way to parse through your content and pull out description. So I know for a fact that it pulls out description. It also pulls out all images. This most likely means that there is another plugin that is interfering on your site.Do you have a WP plugin to add the like box or the like button? or any other FB plugin?
techhogger says
@wpbeginner@waqaslone I tried to share again after your last reply. And the same happens. I can see only post title with description as my blog’s description instead of post description and no thumbnail. I am using Digg Digg plugin for social sharing .
wpbeginner says
@techhogger@waqaslone Please turn on Otto’s Simple Facebook Connect plugin. Remove the code that you have added in your functions.php …
techhogger says
@wpbeginner@waqaslone I think its working now. I downloaded and configured the plugin again. And now it seems to be working. Can you have a look and let me know if everything is fine now.
ChristopherJosephDowney says
I am used to putting meta tags in the HTML on Blogger. Switching to WordPress has been a headache in this aspect, as I have no HTML to edit and am not used to CSS. This plug-in is a dream, but it doesn’t seem to be working correctly. My question is this: It appears I have 3 different ID’s: My facebook profile, my facebook fan page (the one my blog links to) and my OG debugger ID that appears on the developer debugger page; which ID do I need to use for the plug-in? No matter which one I put in the plug-in when I click « debug » the thumbnail does not update and is always one of the advertisement’s gif’s. Can I have more than one default thumbnail like I would using megatags in HTML?
RobKara says
When a user hits my wordpress page « object » then how do i get the facebook userid if its a facebook user viewing the page? Does facebook send a signed_request or facebook userid via the querystring?
wpbeginner says
@RobKara This question should be asked in the Open Graph forum because it is beyond the scope of this article.
MetalPhil says
So I installed this stuff on my website (AngryMetalGuy.com) and it doesn’t work. I have *no* clue why. I am beyond frustrated and super confused. If you could please, please, please, please, pleeeease help me that would be awesome.
MetalPhil says
BTW: I installed it a long time ago and it still doesn’t work. I’ve been having this problem for over a month now. It’s killing me.
lizbizz says
I Deactivated the Facebook OG Meta plugin on my blog and Installed the Simple Facebook Connect plugin instead and now everything seems to be working right on my site and posts!
WPbeginners. com instructions and info (be sure to follow them exactly) using this post: https://www.wpbeginner.com/plugins/how-to-install-and-setup-simple-facebook-connect-for-wordpress/
lizbizz says
This solved my problem for the Share on Facebook button, but now when I try to share a post from my site to Facebook using Hootsuite’s Hootlet, the description text box is empty. It shows the correct thumbnail and URL but no article preview text. It worked before and still works for other sites, so I think it happened when I installed the plugin…help?
SaijoGeorge says
@wpbeginner Facepalm … Thanks for the quick replay mate
wpbeginner says
@SaijoGeorge It will only output your post’s defined excerpt. If you don’t specify an excerpt, then nothing will be displayed.
SaijoGeorge says
Great plugin .. the only issue I seem to be having is that the meta property= »og:description » spits out some random data
. Thr url for a sample post is 1800pocketpc.com/watch-out-for-windows-phone-7/22453/ similar issue on another blog bestwp7games.com/crazy-horses-match-maker-a-path-drawing-game.html ( here og:description comes out to be blank ) I am using thesis variations on both of those sites .. was wondering if any of you guys have come across this issue
It’s also worth noting that meta description tag on those pages seems to ouput the right data
wpbeginner says
@CarlosDeGuzman It takes a while for the linter to update.
CarlosDeGuzman says
Hi wpbeginner! I installed the plugin on my site, ww w.swimbikerun.ph and it’s not working. I’m still getting these errors on the linter. Also no thumbnails are showing when you share a post on fb. Hope you can help
Also its not showing the description
Warning

@ReyCalantaol It has nothing to do with SEO…. the Open Graph data is for Facebook…..
wpbeginner says
@arabsciences@Tia Peterson You have to add the Meta Description and our plugin does that for you…
wpbeginner says
@arabsciences@Tia Peterson You have to add the Meta Description and our plugin does that for you…

Hi
How do pull description from aal in one seo plugin.?
it it not working for me
arabsciences says
@Tia Peterson@wpbeginner
I use All in one seo plugin and could not pull the description to show in url linter
arabsciences says
@Tia Peterson@wpbeginner
I found a fix for that which shows first 300 characters of the post.
just change og:description to :
<meta property= »og:description » content= »<?php echo strip_tags(get_the_excerpt($post->ID)); ?> » />
ClyoBeck says
Okay, I’ve gone back to the original theme files and uploaded the original functions.php file. No go. Still a blank screen. I’m thinking up upgrading the theme to see if that will help. I’m wondering if the code I put in the functions.php file, somehow, changed something else. Is that possible?
wpbeginner says
@ClyoBeck Make sure that there are no extra spaces at the bottom of the functions.php file …
ClyoBeck says
Hi guys,
I should have just downloaded the plug-in. Instead I copied and pasted the code above into my functions.php file and now my blog has disappeared.
I went into my server and, having made copies of the php file in notepad, uploaded the old file. Still no luck.
Looks like I’m going to have to hire a programmer to fix this.
Any advice?
Livefyre says
@wpbeginner Thanks. I don’t think I got the update, though. Should I just download the plugin again from the WP plugin repository and re-install?
wpbeginner says
@Tia Peterson Just uploaded the fix for this and another issue. It should be live within 15 minutes or sooner (whenever the SVN updates go through).
wpbeginner says
@SteveJoseph@joshuatj Also with the linter (not sure exactly what the number is) but if your post has that many likes, then it won’t reset the description / title and such… If I am correct, then that number is not very high…
SteveJoseph says
@wpbeginner@joshuatj Thanks for the response wpbeginner. I tried your plugin within the last 3 days so was fairly certain it was the latest version but that didn’t seem to work for me. I’m going to go with your suggestion that it will fix itself but the current solution is not the most ideal. It’s pulling the description from my blog « intro » section which is helpful in telling the audience about me but does very little to support why they should click on the article or shared item. Thankfully it does show the correct image and post headline just not the description from the post itself.
Since Facebook hyped open graph so much you’d like to have imagined they would have made sure this was working and buttoned up pretty solid. Thanks again.
Tia Peterson says
Hi! For some reason, the plugin doesn’t pull a description. At first, I figured out that it was pulling the description from the ‘excerpt’ field, so I started using that field every time. Now, it doesn’t even pull from that. Not sure why. I am using the latest version of the plugin, StudioPress News Child Theme for Genesis, and WordPress version 3.1.
Here is our most recent post to show you that when you paste this URL into Facebook, only the image and title show up. In the source code, the description field for the open graph plugin is completely empty. http://www.bizchickblogs.com/2011/08/what-do-you-know-about-naturopathy.html
Thanks for your help!
wpbeginner says
@SteveJoseph Facebook takes a bit long to update older posts, but it will fix itself.
