GetImages
This is what I use on my blog to automagically pull out the first 3 images in the content of the blog post and display them with Ditto
<?php
//If no documents then return
if(!isset($ids)){ return; }
//limit the number of images outputted
$field = (isset($number))? $number : 3;
//Make an array of all ids
$docArray = explode(',',$ids);
$docs = $modx->getDocuments($docArray, 1, 0,"id,content");
//For each document
foreach ($docs as $doc){
$html .= $doc['content'];
preg_match_all('/<img[^>]+>/i',$html, $images);
//print_r($images);
//This should append $images to a bigger array
}
for($i=0; $i<$number; $i += 1){
$output .= $images[0][$i];
}
return $output;
?>
