pharmTekFYI - I think I understand how to fix my problem but am only code at editing existing code and could really use some help writing this fix.
So here's the problem... I now have 2 thumbnails showing on my single post page... why?
Because I've added the following code to my functions.php:
//check attachment
function checkimage($size=medium) {
if ( $images = get_children(array(
'post_parent' => get_the_ID(),
'post_type' => 'attachment',
'numberposts' => 1,
'post_mime_type' => 'image',)))
{
foreach( $images as $image ) {
$attachmentimage=wp_get_attachment_image( $image->ID, $size );
return $attachmentimage;
}
}
}
//get attachment
function postimage($size=medium) {
if ( $images = get_children(array(
'post_parent' => get_the_ID(),
'post_type' => 'attachment',
'numberposts' => 1,
'order' => 'ASC',
'post_mime_type' => 'image',)))
{
foreach( $images as $image ) {
$attachmentimage=wp_get_attachment_image( $image->ID, $size );
echo $attachmentimage.apply_filters('the_title', $parent->post_title);
}
}
}With corresponding code in my single.php file to show the image attached to each post:
<?php if(checkimage()) { // if there is an image ?>
<?php postimages('medium'); ?>
<?php } ?>(which have been uploaded via the default media gallery)
This all works great except for in the case when I need to use a custom field key to embed a thumbnail (which is necessary for one particular page due to the styling of those posts).
What I need now is some conditional code to fix the problem... I'm thinking it should be something like:
Checkimage
IF there is a thumbnail THEN post thumbnail and END
ELSE postimage
Does that sound right? and if so... what's the code for that?
