Hi Swanson,
I am using Bones themes , Reason I wan it to be slug is because I will turn it to become a custom field, so I can just insert slug name instead of ID name.
Then use a function to grab the slug of the post id as shown in the second link.
Thanks for the quick reply…
Sorry my scripting knowledge is really beginner
I have insert this script in function.php
function the_slug() {
$post_data = get_post($post->ID, ARRAY_A);
$slug = $post_data[‘project-123’];
return $slug;
}
And in my page.php when I call this function out, it just throw out error
<?php echo get_the_post_thumbnail(the_slug(), ‘thumbnail’); ?>
I know the way I insert the_slug() is wrong, I try a lot of way to writing it
the_slug()->ID ,
I even not using function straight
$post_data = get_post($post->ID, ARRAY_A);
$slug = $post_data[‘project-123’];
<?php echo get_the_post_thumbnail($slug ‘thumbnail’); ?>
But all just went wrong…can point me out the correct way of writing it?
Thank you
First, use the function the way is was presented…then try:
<?php $args = array(
'post_id' => the_slug();,
'size' => 'thumbnail',
);
echo get_the_post_thumbnail($args);
?>
Above is not tested…need a foreach?
Hi Swanson,
I still can’t get it work, it since like the code from this link have error
http://www.wprecipes.com/wordpress-function-to-get-postpage-slug
function the_slug() {
$post_data = get_post($post->ID, ARRAY_A);
$slug = $post_data[‘post_name’];
return $slug;
}
<?php echo the_slug(); ?>
I try copy and paste exactly without changing any thing and it show error in the page…
get_the_post_thumbnail() only accepts a post id.

To get the ID from a slug so you can use it in the function use this:
http://ww.wp.xz.cn/support/topic/how-can-i-get-the-page-id-from-a-page-slug
Here’s an example:
<?php
// get the slug from the custom field
$slug = get_post_meta( $post->ID, 'slug', true );
if ( '' != $slug ) {
// get the post id from the custom field slug
global $wpdb;
$my_id = $wpdb->get_var( "SELECT ID FROM $wpdb->posts WHERE post_name = '$slug'" );
// display the post thumbnail.
if ( $my_id ) {
echo get_the_post_thumbnail( $my_id , 'thumbnail' );
}
}
?>
