not working because all posts use the same thumb.tried hard to found out what's happening but can't. !just realized the thumb is still the same 1 image for all posts, but the cache folder (phpimageresize) contains all resized images.thanks for any help. sry for the bump. <div class="thumb"> <a href="<?php the_permalink() ?>" title="<?php the_title(); ?>"> <?php $settings = array("w"=>100,"h"=>100,"crop"=>true); $values = get_post_custom_values("thumbs"); ?> <img src="<?php echo resize($values[0], $settings); ?>" alt="<?php the_title(); ?>" /> </a> </div>

working thank you! but it returns the same thumbnail for all posts

it returns the image url from the custom field named "thumbs" source: /** * Retrieve values for a custom post field. * * The parameters must not be considered optional.

thanks! allmost work i made a little changes, take the alt attribute to the right place: <img src="<?php $values = get_post_custom_values("thumbs"); echo $values[0]; echo $settings; ?>" alt="<?php the_title(); ?>" /></a> and the output is now: <img src="http://anydomain.com/anyimage.jpgArray" alt="alt" /></a> the only problem now is the word Array is appear after the .jpg extension. edit: the thumb code is this: <div class="thumb"> <a href="<?php the_permalink() ?>" title="<?php the_title(); ?>"> <?php $settings = array("w"=>100,"h"=>100,"crop"=>true); ?> <img src="<?php $values = get_post_custom_values("thumbs"); echo $values[0]; echo $settings; ?>" alt="<?php the_title(); ?>" /></a> </div>

Hello phpfreaks! i'm moln4r from hungary and registered here because i stucked with a php function in my wp template and want to ask you some help. I want to use phpimageresize to cache/resize and display my external thumbnails. this sounds easy even for a noob like me, i tested on the server in a standalone php file and it works fine, but when i tried to put the code inside my template loop i found this: <img src="<?php $values = get_post_custom_values("thumbs"); echo $values[0]; ?>" width="128" height="96" alt="<?php the_title(); ?>" /></a> ok wp getting the image from a custom field, and here we are... I can't mix the two code without syntax error. but i'm a noob so please somebody help me. this code call the phpimageresize function: <img src="<?=resize("http://anysite.com/anyimage.jpg" ,$settings)?>" /> and this is my default thumbnail: <img src="<?php $values = get_post_custom_values("thumbs"); echo $values[0]; ?>" width="128" height="96" alt="<?php the_title(); ?>" /></a> so it must be something like this, but my knowledge ends here: <img src="<?=resize("<?php $values = get_post_custom_values("thumbs"); echo $values[0]; ?>" ,$settings)?>" /> please help me how can I make this work. Thanks
