Change image size from facebook feed

Yes. I was just working with this today actually. Try pasting this into your functions.php file. I’m working on a plugin add-on, but this was the snippet I used.

function fwp_facebook_image( $content )
{
    $content = preg_replace_callback(
        '|https://fbcdn-photos-f-a.akamaihd.net/.+_s\.jpg|',
        function ( $matches ) {
            return str_replace( '_s', '_o', $matches[0] );
        },
        $content
    );
}
add_filter( 'syndicated_post', 'fwp_facebook_image', 10, 2 );

I forgot the important last line inside the function!

return $content;

Hello Beer,

thank you for the code. But unfortunately it doens′t work. When I use the code, the import don′t run. If I ad the return $content; for the last } there is a php error. What is wrong?

Sorry. I was working on too many things at once and that snippet wasn’t enough in this context to handle it for you. This should fix it.

function fwp_facebook_image( $data )
{
    $data['post_content'] = preg_replace_callback(
        '|https://fbcdn-photos-f-a.akamaihd.net/.+_s\.jpg|',
        function ( $matches ) {
            return str_replace( '_s', '_o', $matches[0] );
        },
        $data['post_content']
    );
    return $data;
}
add_filter( 'syndicated_post', 'fwp_facebook_image', 10, 2 );

Hello Beer,

The regular expression I was using matched mine. I didn’t realize the host name is changing. I took a look at yours for example and see the hostname to the image is different.

Mine is fbcdn-photos-f-a.akamaihd.net/
Yours is fbcdn-photos-d-a.akamaihd.net/

So we need to adjust that.

Change this
'|https://fbcdn-photos-f-a.akamaihd.net/.+_s\.jpg|',
to this
'|https://fbcdn-photos-[a-z]-a.akamaihd.net/.+_s\.jpg|',

and let me know if that works.

Hello Beer,

thank you very much! It works now. You just made my day!

Hello Beer,

I hope, you could help me one more time:

In the feed (https://www.facebook.com/feeds/page.php?id=136113746547580&format=rss20), the german “ü” (für) is wrong. How can I fix it? I played with your code

function fwp_facebook_text( $data )
{
    $data['post_content'] = preg_replace_callback(
		'|für|',
        function ( $matches ) {
            return str_replace( 'für', 'ü', $matches[0] );
        },
        $data['post_content']
    );
    return $data;
}
add_filter( 'syndicated_post', 'fwp_facebook_text', 10, 2 );

… but it doens′t work.

Regards,
Jan

You have to look at the feed. It looks like it’s using f& #xfc ; r as the text for that, so that’s what you’d work with to replace. If you already were, then I’m not sure yet without digging into the html* mb* or iconv functions.

I’ve been struggling with this same thing myself where I want the full sized image from the Facebook feed because I’m using FeedWordpress to post it to a blog. The problem is that the _s vs n thing doesn’t apply to every image.

For instance: https://external.ak.fbcdn.net/safe_image.php?d=AQB-l0qAOric8sGM&w=154&h=154&url=https%3A%2F%2Fpbs.twimg.com%2Fmedia%2FBshbk-NCYAEx4zK.jpg and https://fbexternal-a.akamaihd.net/safe_image.php?d=AQBUg42gulLaQ2M7&w=484&h=253&url=https%3A%2F%2Fpbs.twimg.com%2Fmedia%2FBshbk-NCYAEx4zK.jpg&cfs=1

Did this change since you guys were discussing this or am I missing something?
