I'm working on a project where the images are not placed into the content area but instead are displayed by grabbing the post attachments.  When I put my code into the print-posts.php template, it is grabbing an image attachment of another post instead of the one I am trying to print.

Here is my print page - http://frontporch.clientpod.com/products/case-pieces/desks/french-satinwood-desk/print/
As you can see, it is pulling an image of a lamp instead of the desk image.

Within the loop of the print-posts.php template, I placed the following code:

Code: [Select]

<?php 
$args = array(
'order'          => 'ASC',
'post_type'      => 'attachment',
'post_parent'    => $post->ID,
'post_mime_type' => 'image',
'post_status'    => null,
'numberposts'    => 1,
);
$attachments = get_posts($args);
if ($attachments) {
foreach ($attachments as $attachment) {
echo wp_get_attachment_image($attachment->ID, 'large', false);
}
}
?>

Any help as to why its not grabbing the correct image would be greatly appreciated.  I also plan to use the WP-Email plugin for such a task.  Thanks again for your time and hard work on these great plugins.

I am guessing that the get_post() will corrupt the current loop aka query_posts() or the query_posts() replace the variable of get_post(). Try placing it outside the loop.

When I place it outside of the loop it acts the same, still grabbing the lamp image.  The snippet of code I'm using to grab the attachments is meant to be placed inside the loop and seems to work fine in my single.php template file, so what could be causing it to break in this instance?

I guess I could use a custom field for the print image, but its one additional step I was hoping to avoid.

Your thoughts are greatly appreciated.

Did you try to echo the $post->ID to see it reflects correctly?

[phycel]

Ok, if I try echo $post->ID inside/outside the loop, nothing shows up.  If I try the_ID(); inside the loop, I get the correct ID.  For some reason $post->ID is not working the way it should.  I did test my code in a post and was able to get the correct ID to echo... its just not working in the print-posts.php template.  Of course, I know I must be doing something wrong because the template displays the correct title, content, and url.

Well, I figured there's gotta be a way around this minor issue... so I hacked my image attachment code a little bit.  Just thought I'd share.

Code: [Select]

<?php   
function recall($data)
{
   $GLOBALS['d'] = $data;
   return '';
}
ob_start("recall");
the_id();
ob_end_clean();

$args = array(
'order'          => 'ASC',
'post_type'      => 'attachment',
'post_parent'    => $GLOBALS['d'],
'post_mime_type' => 'image',
'post_status'    => null,
'numberposts'    => 1,
);
$attachments = get_posts($args);

if ($attachments) {
foreach ($attachments as $attachment) {
echo wp_get_attachment_image($attachment->ID, 'large', false);
}
}
?>

Hopefully I can get it to work with the wp-email plugin too!    Thanks for all your help with everything.  I always like using your plugins because I know how well you support and document everything.  As always, a pleasure.

Thanks, if you want to return instead of echo, use get_the_id()
