get images urls from post.php

  • Hello everybody,
    Is there a way to get images urls from post.php page? I need to have these since they have to be “printed” in a pdf file that is generated
    with a script (html2pdf) that I’ve added in post.php
    This script creates a pdf every time a post is edited or created (in back office only) and I must include images’ urls too…

  • <?php
$image = wp_get_attachment_url( get_post_thumbnail_id($post->ID) );
echo $image;
?>

    Hope it helps.

    Thanks.

    Thank you very much for replying.
    Unfortunately if I try functions like wp_get_attachment_url (even without the echo command), I get a blank page instead of the edit one…

    BTW, “echo $post->ID” does not print anything….

    Make it global $post;

    <?php
global $post;
$image = wp_get_attachment_url( get_post_thumbnail_id($post->ID) );
echo $image;
?>

    No way ??
    the line “$image = wp_get_attachment_url( get_post_thumbnail_id($post->ID) );” causes a blank page (all the admin area goes off…)

    At (about) line 4148 there’s this function:

    function wp_get_attachment_metadata( $post_id = 0, $unfiltered = false ) {
	$post_id = (int) $post_id;
	if ( !$post = get_post( $post_id ) )
		return false;

	$data = get_post_meta( $post->ID, '_wp_attachment_metadata', true );
	if ( $unfiltered )
		return $data;

	return apply_filters( 'wp_get_attachment_metadata', $data, $post->ID );
}

    I’ve tried to declare $data as global but it is still void outside the function…

    why arent you writing a plugin that does that once save_post is called?
