php - Retrieving & displaying images from a post with preg_match -

-

basically piece of code grab first image of post , display @ page. if no images, show default image.

how modify make display max 4 images ?

<?php  $imagesrc = c('plugin.indexpostimage.image','/images/default.png');  preg_match(     '#\<img.+?src="([^"]*).+?\>#s',      $sender->eventarguments['post']->body,      $images );  if ($images[1]) {     $imagesrc = $images[1]; }  $thumbs ='<a class="indeximg" href="'.      $sender->eventarguments['post']->url .'">'.      img($imagesrc, array('title'=>$sline,'class'=>"indeximg")).'</a>';  echo "$thumbs";

your found images in array $images according to preg_match manual:

int preg_match ( string $pattern , string $subject [, array &$matches [, int $flags = 0 [, int $offset = 0 ]]] )

$matches[1] have text matched first captured parenthesized subpattern, , on.

so should iterate on $images array 1 5 , if $images[$i] not empty add image thumbs. try this:

<?php  $imagesrc = c('plugin.indexpostimage.image','/images/default.png');  preg_match(     '#\<img.+?src="([^"]*).+?\>#s',     $sender->eventarguments['post']->body,     $images );  $thumbs = ""; ($i = 1; $i <= 5; $i) {     if(!empty($images[$i])) {         $thumbs .= '<a class="indeximg" href="' .             $sender->eventarguments['post']->url . '">' .             img($images[$i], array('title' => $sline, 'class' => "indeximg")) . '</a>';     } else {         break;     } }  echo "$thumbs";
