Avete bisogno di caricare sul vostro sito web file che normalmente non sono supportati da WordPress?
In WordPress è possibile caricare molti tipi di file comuni, tra cui immagini, video, file audio e file di Office. Tuttavia, alcuni proprietari di siti web hanno bisogno di caricare file non supportati.
In questo articolo vi mostreremo come aggiungere altri tipi di file da caricare in WordPress.
Quali tipi di file sono consentiti per il caricamento in WordPress?
Per motivi di sicurezza, è possibile caricare sul proprio sito web WordPress o sul proprio negozio WooCommerce solo i tipi di file più comunemente utilizzati. Esiste anche un limite massimo di dimensione dei file che possono essere caricati.
Per impostazione predefinita, i tipi di file e le estensioni consentite sono:
Immagini:.jpg, .jpeg, .png, .gif, .ico, .webp
Documenti:.pdf, .doc, .docx, .ppt, .pptx, .pps, .ppsx, .odt, .xls, .xlsx, .PSD, .XML
Audio:.mp3, .m4a, .ogg, .wav
Video:.mp4, .m4v, .mov, .wmv, .avi, .mpg, .ogv, .3gp, .3g2
Suggerimento: Sebbene sia possibile caricare video su WordPress, consigliamo di utilizzare un sito di hosting video. Ciò contribuisce a proteggere la velocità e le prestazioni del vostro sito web.
Tuttavia, alcuni tipi di file hanno il potenziale per essere utilizzati in modo improprio e possono rappresentare un rischio per la sicurezza, quindi WordPress non li abilita per impostazione predefinita.
Ecco un elenco dei tipi di file bloccati da WordPress:
Immagini come .svg, .bmp
Documenti come .psd, .ai, .pages
File di codice come .css, .js, .json
Video come .flv, .f4l, .qt
Se cercate di aggiungere nuovi tipi di file non supportati al vostro sito WordPress, vedrete il messaggio di errore“Spiacenti, non è consentito caricare questo tipo di file“.
Ma cosa succede se dovete caricare un formato di file non supportato? Potreste caricare i file tramite FTP o il file manager del vostro host WordPress, ma non è così comodo come usare la libreria multimediale integrata di WordPress o un modulo di caricamento dei file.
Suggerimento: se volete caricare immagini con estensione SVG, potete consultare la nostra guida su come aggiungere file SVG in WordPress.
Vediamo come aggiungere altri tipi di file da caricare in WordPress.
Come aggiungere altri tipi di file da caricare in WordPress
Alcuni tutorial indicano di modificare il file functions.php e di aggiungervi uno snippet di codice PHP. Tuttavia, riteniamo che il modo più semplice e sicuro per abilitare diversi tipi di file sia un semplice plugin.
Innanzitutto, è necessario installare e attivare il plugin gratuito File Upload Types by WPForms. Per maggiori dettagli, consultate la nostra guida passo passo su come installare un plugin di WordPress.
È uno dei migliori plugin per il caricamento di file ed è il modo più semplice per aggiungere a WordPress il supporto per altri tipi di file. È stato creato dal fondatore di WPBeginner, Syed Balkhi.
Utilizzo dei tipi di file preimpostati
Dopo l’attivazione, andare alla pagina Impostazioni ” Tipi di file da caricare nell’area di amministrazione di WordPress. È possibile scorrere l’elenco dei tipi di file preimpostati o inserire un tipo di file nella casella di ricerca.
Quindi, selezionare le caselle accanto ai tipi di file che si desidera abilitare.
Una volta terminato, è necessario fare clic sul pulsante “Salva impostazioni” in fondo alla schermata per memorizzare le modifiche.
A questo punto, sarete in grado di caricare questi tipi di file utilizzando la libreria multimediale di WordPress.
Aggiunta di tipi di file personalizzati
Se il tipo di file che si desidera aggiungere non è incluso nell’elenco delle preimpostazioni, è possibile aggiungerlo come tipo di file personalizzato.
Scorrendo verso il basso fino alla fine della schermata Tipi di caricamento file, si troverà una sezione denominata “Aggiungi tipi di file personalizzati”. Qui è possibile aggiungere un nuovo tipo di file inserendo una descrizione, un tipo MIME e un’estensione.
Per aggiungere un altro tipo di file personalizzato, è sufficiente fare clic sull’icona ‘+’ alla fine della riga. Al termine, non dimenticate di fare clic sul pulsante “Salva impostazioni” per memorizzare le modifiche.
Ad esempio, se si desidera aggiungere il tipo di file YAML, si deve digitare “file YAML” nella descrizione, “text/yaml” nel campo del tipo MIME e “.yaml” come estensione del file.
MIME (“Multipurpose Internet Mail Extension”) è un modo standard per identificare i file sul web. Il modo più semplice per conoscere il tipo MIME di un file è utilizzare un MIME File Type Checker.
Speriamo che questo tutorial vi abbia aiutato a capire come aggiungere altri tipi di file da caricare in WordPress. Potreste anche voler imparare a creare un modulo di caricamento file in WordPress o consultare il nostro elenco dei migliori temi WordPress.

‘Sorry, this file type is not permitted for security reasons.’

//Adding different file format

You would want to reach out to your hosting provider, they are likely overriding the files allowed to be uploaded

Allow All File Types
You can also setup WordPress to allow to upload all file types. This can be performed with the help of a WordPress constant “ALLOW_UNFILTERED_UPLOADS”. You can set the WordPress constant “ALLOW_UNFILTERED_UPLOADS” to true” in wp-config.php file of your WordPress install. The wp-config.php file can be found in the root directory of your WordPress install. Using your favorite editor (vi editor) open the wp-config.php file and add the following line somewhere in the file. You can also use File Manager to edit the WordPress configuration file.
define(‘ALLOW_UNFILTERED_UPLOADS’, true)
Don’t forget to save the config file after editing.
WPBeginner Support says
The dangers of a method like this would be that you are allowing every file type to be uploaded to your site which removes some safety.
rob thirlby says
I still cannot get csv uploads to work in 4.9.9 upwards of wordpress. Has anyone got a solution? Just adding the csv type to the list doesn’t seem to help. Is csv explicitly banned in the core somewhere.
Sam Bean says
Is all this still good for WordPress 4.9.2? I also could not find any mime types for Adobe Illustrator files (.AI and .EPS)
Can you tell me what I would add to the file to be able to upload those 2 file types?
Ajeet says
hello sir,
i want to upload .exe file,but it shows an error.So what can i do
WPBeginner Support says
Hi Ajeet,
You cannot upload it by default. You will need to allow .exe file types first. Please see the instructions in the above article.

I did what the instructions say and I still can’t upload .ogv files.

$mime_types[‘ogv’] = ‘video/ogg’; //Adding ogv extension
return $mime_types;
}
add_filter(‘upload_mimes’, ‘my_myme_types’, 1, 1);
Does anybody know why it doesn’t work?

Doing this example I was able to now allow upload of AI file with custom Icon for the file type. I would like to change the icon used for PDF to a PDF icon. Can this be done?
Seems like it just wants to use the default

Diana says
Thanks for this article, I used it today! I have a question. I had to allow .sql file types to be uploaded to wordpress, in order to upload some of my scripts that I would like to share.
The problem is, if I put the script in a link, when I click on the link, the script downloads automatically, instead of opening in a new window.
This is the code I added:
function my_myme_types($mime_types){
$mime_types[‘sql’] = ‘text/x-sql’; //Adding sql extension
return $mime_types;
}
add_filter(‘upload_mimes’, ‘my_myme_types’, 1, 1);
When can I change the behavior? Also after the file is uploaded it says it is SQL type.
Thanks
Diana
Darren says
So, it would be nice if we knew where to add the code??????????????????
Thanks
WPBeginner Support says
All custom code in the article goes into your theme’s functions.php file or a site-specific plugin

Kevin says
At the bottom of the functions.php page. At the top? Is there already a place I add them to, like under the allowed file types already there? (jpg,gif,mp4,etc…)
I’ll try at the bottom and see what happens.
Kevin says
Worked. For the people wondering. I just scrolled to the end of that page and pasted the code in there. If you copied and pasted the code up there, don’t be like me and leave the numbers. Just erase the numbers.
And if you’re like me, you just skimmed through to find what you’re looking for. I couldn’t find what I had to put so it would open the right program, it’s in that link that’s hidden between the snippets of code up there. “File extensions” is what you’re looking for. Go to that page and look up your extension you want to add, I wanted to add KML and KMZ for my wiki on a stick and it looks like this…
function my_myme_types($mime_types){
$mime_types[‘kml’] = ‘application/vnd.google-earth.kml+xml’; //Adding kml extension
$mime_types[‘kmz’] = ‘application/vnd.google-earth.kmz’; //Adding kmz files
return $mime_types;
}
add_filter(‘upload_mimes’, ‘my_myme_types’, 1, 1);
All I did was copy and past the code up there and changed the file extension and the… other part. Worked like a charm.
Oh, the finctions.php is in appearance -> Editor -> On the right side of that page, Theme Functions (functions.php). Just scroll to the end of that page and add your code there.
Bruno says
Kevin, whats your WP version? Mine is 4.2.4 and it doesnt work!…
Jeremy Taylor says
Adding the code looks pretty easy but it is not clear where I should add the code. Where do I go from my dashboard to add it? I’m using WordPress 4.3.1.
Thanks
Jeremy
Kymmie says
Go to Appearance > Editor > Look for functions.php and just add the code to the bottom. Don’t forget to put a label like
//Adding different file format
so you would know.
Bry says
Hi There.
Thanks for the really useful information…
I managed to get the different file types (.IES and .LDT files) to upload ok following your advise above but unfortunately they do not download as files, but rather as code….any tips on how to fix this issue?.
Thanks in advance for your help.
Regards
Bry
Bry says
This is the code i used in the theme-function.php file..
function my_myme_types($mime_types){
$mime_types[‘ies’] = ‘application/octet-stream’; //Adding .ies extension
$mime_types[‘ldt’] = ‘application/octet-stream’; //Adding .ldt extension
return $mime_types;
}
add_filter(‘upload_mimes’, ‘my_myme_types’, 1, 1);
Sara says
THX. That’s useful
WPBeginner Staff says
Yes, CSS.
Mark Gandy says
How do you get the file type’s small icon (the file type logo) to load automatically where it will be positioned next to the name of the file (which is a link)? I’m guessing that’s CSS?
