Help needed extending custom function
-
Hi all I am using the following custom function to display a thumbnail automatically taken from the first image in the post and it works great.
<?php // This Function Powers the thumbnail image that is used in my portfolio function return_ThumbNail($Thumb) { if (preg_match('/<img[^>]*>/',$Thumb,$Treffer)) { $Thumb = preg_replace('/(<img ).*(src=\'[^\']*\').*( \/>)/','$1$2$3',$Treffer[0]); $Thumb = preg_replace('/(.[^.]* \/>)/','.thumbnail$1',$Thumb); } else { $Thumb = false; } return $Thumb; } ?>
I would like to extend this function to also pass the thumbnail the relevant “alt” text. I know this is probably simple but my php regular expression skills are not very good.
Tom
