Displaying all images from a WordPress post

Question

I have this piece of code I found on some blog, that\'s supposed to display all images from a WordPress post.

function getImage() {
    global $more;
    $m         


        

Answer 1

Try this ! It may work.

function getImage() {
    global $more;
    $more = 1;
    $link = get_permalink();
    $content = get_the_content();
    $count = substr_count($content, '<img');

    for($i=1;$i<=$count;$i++) { 
        //move $start = 0 inside the loop
        $start = 0;
        $imgBeg = strpos($content, '<img', $start);
        $post = substr($content, $imgBeg);
        $imgEnd = strpos($post, '>');
        $postOutput = substr($post, 0, $imgEnd+1);
        $postOutput = preg_replace('/width="([0-9]*)" height="([0-9]*)"/', '',$postOutput);;
        if(stristr($postOutput,'<img')) { echo $postOutput; }
        $content = substr($content,$imgEnd+1);
    }
    $more = 0;
}

Answer 2

its easier now with the new wordpress get_attached_media($type,$post) function

$attachments= get_attached_media( 'image', $post->ID );
foreach($attachments as $att_id => $attachment) {
  $full_img_url = wp_get_attachment_url($attachment->ID);
// You can echo it out here
}

note that this gets only the files uploaded to the post . not files added through media library.

Fixed, you need to add an $imgLength.

function getImage() {
    global $more;
    $more = 1;
    $link = get_permalink();
    $content = get_the_content();
    $count = substr_count($content, '<img');
    $start = 0;
    for($i=1;$i<=$count;$i++) {
        
        $imgBeg = strpos($content, '<img', $start);
        $post = substr($content, $imgBeg);
        $imgLength = strpos($post, '>');
        $imgEnd = $imgBeg + $imgLength;
        $postOutput = substr($post, 0, $imgLength+1);
        $postOutput = preg_replace('/width="([0-9]*)" height="([0-9]*)"/', '',$postOutput);;
        if(stristr($postOutput,'<img')) {    
            echo $postOutput;
        }
        $start=$imgEnd+1;
    }
    $more = 0;
}

$attachments = get_children(array('post_parent' => $post->ID,
                        'post_status' => 'inherit',
                        'post_type' => 'attachment',
                        'post_mime_type' => 'image',
                        'order' => 'ASC',
                        'orderby' => 'menu_order ID'));

foreach($attachments as $att_id => $attachment) {
    $full_img_url = wp_get_attachment_url($attachment->ID);
    // Your Code here
}

<?php
    if ( have_posts() )
    while ( have_posts() ):
    the_post();

    $args = array(
        'post_type'   => 'attachment',
        'numberposts' => -1,
        'post_parent' => $post->ID
        );

    $attachments = get_posts( $args );

    if ( $attachments )
    {
        foreach ( $attachments as $attachment )
        {

        echo wp_get_attachment_image( $attachment->ID, false );

        }
    }

    endwhile;
?>
