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.

This is indeed helpful but SEO Yoast’s interface doesn’t look like this anymore. This needs updating.

Thanks for the tutorial. I’ve been adding Open Graph in AIO SEO and I’m still surprised that AIO SEO tells me there isn’t one. I spent about half an hour on this before I found out that I had to click refresh again in the SEO evaluation so that the plugin would download the new WordPress settings and do a new SEO analysis. Such a simple thing and it took me so long.
Harry Goldhagen says
Hello, thanks for the code snippet, I look forward to trying it. One question, will it then allow FB to pick up the featured image (is that the « thumbnail »?) and excerpt for each blog post, or will it just use the sitewide logo image designated in line 19? I’ve tried Blog2Social, but the posts lacked the featured image and excerpt and did not look good. Thanks!
WPBeginner Support says
The code snippet should set your featured image to the featured image of the post.

Kiss Attila says
Hi,
Awesome code. BUT, why it’s not changes og:url and og:image. I tried with a post with no image set as default. But checking it on fb debugger, it picks up my logo from the footer instead of getting the image I added in the og:image part.
Title is working it changed from the origin and I pasted og:description too. All the most important metas but image and url.
Why is that?
Thanks,
Atila
WPBeginner Support says
Please ensure you’ve cleared any caching on your WordPress site as that is the most common reason it would not update to match the code.

hi how can i modify the code to add OG tags for custom post types i tried by changing this line code if ( !is_singular()) to if ( is_singluar( array( ‘post’, ‘publications’) ) ) but my website throw fatal error. can anyone please help thank you
WPBeginner Support says
You should not need to modify the code to work with custom post types and it should work on them

Hello, i tried all the solution suggested still i miss some parameter to the schema:
A required field is missing: id
A required field is missing: price
A required field is missing: availability
Is there any solution via plugin or updating the function.php code?
WPBeginner Support says
That would be markup for a product you are selling on your site and All in One SEO does have the option to add that markup to your products.

Does this also work for sms text message url previews or just Facebook?
WPBeginner Support says
While not specifically for SMS messages, the markup helps with that as well.

If I use the Yoast SEO settings, will it take times for showing the perfect result in facebook share? Or will it start working within minutes?
WPBeginner Support says
That would depend on your site’s caching and any caching on Facebook for how long it takes
Administrateur
Indranil Paul says
I’m facing this problem in all social sharing sites.
WPBeginner Support says
If it is not showing what you set on every social site, you would want to reach out to Yoast’s support and let them know to ensure there isn’t a problem with the plugin.

Hello
Please can you advise when using a child theme – do i need to copy the parent theme functions.php and then add the above script to a newly created functions.php and upload it to the child theme folder OR do I just add the script to the parent theme functions.php
Thanks for reading Sadie
WPBeginner Support says
Hi Sadie,
You can add it to either functions.php file.

All Good, But still one problem, How to add Facebook ID..After using this code, following Facebook ID message appears.
The ‘fb:app_id’ property should be explicitly provided, Specify the app ID so that stories shared to Facebook will be properly attributed to the app. Alternatively, app_id can be set in url when open the share dialog.
Eric Hepperle says
I enjoyed this article, but in January 2018 this *manual code* option doesn’t appear to work completely. For instance, though I have verified that the default image property works, when I create a new post, I don’t see ANYWHERE a field where one can begin to edit « open graph (og) » metadata.
Suggestions? Thanks!
Mahesh Yadav says
Thanks for such great information. But I have one question.
How helpful it is to add facebook graph meta data in our site..?
And if it is very much helpful, for what purpose, it is helpful..?

This plugin gave me a white screen of death, obviously a conflict with something or memory exceeded

Does my Facebook profile have to be public in order for my Facebook User ID to be good to use here?
Martin says
I’ve added the code for manually adding this to my theme. However, things aren’t working. Does my profile have to be public in order for my Facebook user id to be accessible?

Hi Martin,
Yes it would work.

Is this still valid for today? I tried it and works, but I noticed in the code the following: « xmlns:fb= »http://www.facebook.com/2008/fbml »‘;
Isn’t 2008 a little old? Is there a newer protocol we should be using today?
Wagner Lungov says
Hello, thanks for posting. I remained with one doubt. I understood that the in each post is dynamically constructed by the functions you explained so well. What I can’t figure out is where the variables called by that function are defined and stored. When you put property= »og:type » content= »article »/, OK you are defining with a fixed string. But when you use: property= »og:title » content= »‘ . get_the_title() . ‘ », where is the function get_the_title() going to get it? How can I define before hand those values for each post in a way that the code will pick the right meta data for each parameter?
Jordan Carter says
get_the_title() will get your post title. If you want to use something else, you could always get the value from a meta box. With the advanced custom fields plugin, it would be something like get_field(« my_field »), or with a regular WordPress custom meta field it would be get_post_meta($post->ID, « my_field », true). See get_post_meta()
Jolanda says
Nicely explained! I try to figure out where I can add the code in checking the size of the featured image, since FB needs a size with a minimum of 200px for both width and height, otherwise it will use another image from the post.
Any help would be great!
Mohsin Rafique says
Nicely explained & works like a charm.
Devyn says
I’ve been trying to use Yoast to enable my meta data so I can use Rich Pins on Pinterest. I’ve done what this tutorial says, but Pinterest still won’t recognize my post. Is there another plugin I could try?
Michelle says
I added the Yoast plugin and there is no social option. Please help me. I am at my wits end with this issue.
Brent Watkins says
Same problem here.
Glenford says
Once you have Yoast installed the look under SEO » Dashboard » Titles & Metas and under that is Social.
in Social you should Enable the « Add Open Graph meta data » in the Facebook tab.
Xavier says
This option just isn’t there with v4.6 of the plugin.
Under SEO >> Dashboard, the tabs I have are: Dashboard, General, Features, Company info, Webmaster tools and Security. No mention of Titles & Metas or Social.
Is this because I haven’t set up a Facebook social profile? Surely this shouldn’t be needed just to be able to configure OG stuff!
WPBeginner Support says
Hey Xavier,
First you would need to go to SEO » Features page and then click ‘Enable’ under ‘Show Advanced Settings Pages’ option. This will display advanced settings pages in Yoast SEO. For more details see our article on how to install and setup Yoast SEO.
joe Barrett says
I added social sharing to the search result template, so each excerpt has a share button BUT the meta data that is shared is messed up and uncontrollable with this, is there a way to make this work better when there are 20 reuslts on the same page with different meta description for each?

I’ve downloaded the Yoast plugin, and set it up for my home page, but when I enter the website on Facebook it still won’t show the image I’ve specified, or the text snippet I’ve written.
Also can’t find my Facebook URL using the link you provided, it just gives me an error…
I tried debug but it says Facebook pages can’t be debugged, and they have no cache.
Sooooo….nothing has worked so far!

You need to enter your WordPress site URL in the debug tool.

I just wanted to thank you for this very thorough description on the process of connecting facebook to your wordpress page. I’ve been trying to do for days now following other sites and recommendations. This evening I came across your page from a google search and bam, it worked. Hooray! Thanks a lot.
Amanda Paul says
Thanks for this info. It was really easy to follow. I uploaded the Yoast plugin and followed all the steps and saved but the thumbnail is still just a blank box. does it take some time to flow through? Do I need to log out and back in again to Facebook? or WordPress?

I have the same problem, also getting og:description missing

me too – any help?
AC says
I have the same problem, and I cannot use FB debugger because i work in localhost…
Marc says
this worked for me:
$metadesc = strip_tags(get_post_field(‘post_content’, $post->ID));
echo »;
(my posts had a very short content)
Kim McCann says
The following works by pulling from your excerpt. Just add under og:title
WPBeginner Staff says
Check your page using Facebook debug tool
https://developers.facebook.com/tools/debug Usually checking a page with the debug tool refreshes the Facebook’s cache and you will be able to see the new image.
BK says
Thank you for taking the time to reply. Will give it a shot!
BK says
Thanks for this. I want to share link directly from my site using the social button. However, when I click on for example the Facebook share button, the image and the description is still using a previous information. Although I have updated the image and description using Yoast SEO and specifically customise the image and description for that post. May I know what did I do wrongly?

Great tutorial, i want to know is there any tutorial about open graph meta for Google Plus ?

Did you set a featured image? did you replace the default image URL in the code with your own image URL?
