marinaavilaOlá, estou usando o automatic post thumb e ele disponibiliza uma imagem padrão para quando não há nenhuma. só que eu quero que ele leia a imagem que eu coloco no post que fica dessa maneira: http://www.site.com/imagens/VALOR DE UM CUSTOM FIELD.jpg
vou postar a versão original e o que eu tentei fazer e ele não conseguiu ler:
VERSÃO ORIGINAL
<?php
/*
Plugin Name: Automatic Post Thumb
Plugin URI: http://devolux.org/post-thumb
Description: The plugin generates a thumbnail from the first image uploaded to a post.
Author: Devolux
Version: 1.0

*/
function post_thumb() {
global $id, $wpdb;
//reading from database
$image_data = $wpdb->get_results("SELECT guid, post_content, post_mime_type, post_title
FROM $wpdb->posts
WHERE post_type = 'attachment' && post_parent = $id && post_mime_type LIKE '%image%'
ORDER BY ID ASC");
$first_image_data = array ($image_data[0]);
//array output
foreach($first_image_data as $output) {
//if there is no description use title (filename) instead
if (empty($output->post_content) == TRUE)
{$output->post_content = $output->post_title;}
//images
if (substr($output->post_mime_type, 0, 5) == 'image')
{echo "<img src=\"$output->guid\" alt=\"$output->post_title\" title=\"$output->post_content\" /> \n";}
else
{echo "<img src=\"".get_bloginfo ('url')."/wp-content/plugins/post_thumb/wp_default.png\" alt=\"default image\" title=\"$output->post_content\" class=\"post_img\" /> \n";}
}
}
