Retrieving all Links from a Post?

1 Views

i’m using the default “insert video” function from wordpress (which inserts a normal hyperlink to the video only) and would like to replace that link with something else like a video player.

my question:
what’s the regex pattern for grabbing all links inside a post?
thx

  1. I’ll answer your question below, but have you looked at using embeds? Look here for more information: http://codex.wordpress.org/Embeds

    The simplest regex for this would look something like http://.*b

    Here’s an example of it in action:

    <?php 

$file = 'test.txt';

$fp = fopen($file, 'r');

$contents = fread($fp, filesize($file));

$matches = array();

preg_match_all('/http://.*b/', $contents, $matches);

print_r($matches);

?>

    Where the file I reference looks like this:

http://www.youtube.com/

http://ca3.php.net/manual/en/function.preg-match.php

    and the return looks like this:

    Array
(
    [0] => Array
        (
            [0] => http://wordpress.stackexchange.com/questions/12809/retrieving-all-links-from-a-post
            [1] => http://www.youtube.com
            [2] => http://ca3.php.net/manual/en/function.preg-match.php
        )
