我无法在自定义帖子类型中找到我的附加图片。 functions.php中的代码
$prefix = 'custom_';
$custom_meta_fields = array(
array(
//'label' => 'Textarea',
'desc' => 'A description for the field.',
'id' => $prefix.'textarea',
'type' => 'textarea'
)
);
// Default metabox for custom post types.
function avz_custom_meta_box() {
// $post_types = get_post_types( array( 'public' => true ) );
$post_types = get_post_types();
foreach ( $post_types as $post_type ) {
if ( $post_type == 'page' || $post_type =='post' )
continue;
add_meta_box(
$prefix.'image',
'Header Image Upload Box',
'show_avz_custom_meta_box',
$post_type,
'normal',
'high' );
}
}
add_action('add_meta_boxes', 'avz_custom_meta_box');
function show_avz_custom_meta_box() {
global $avz_custom_meta_box_fields, $post;
// Use nonce for verification
echo '<input type="hidden" name="avz_custom_meta_box_fields_nonce" value="'.wp_create_nonce(basename(__FILE__)).'" />';
// Begin the field table and loop
echo '<table class="form-table">';
foreach ($avz_custom_meta_box_fields as $field) {
// get value of this field if it exists for this post
$meta = get_post_meta($post->ID, $field['id'], true);
// begin a table row with
echo '<tr>
<td>';
switch($field['type']) {
case 'image':
$image = get_template_directory_uri().'/images/image.png';
echo '<span class="custom_default_image" style="display:none">'.$image.'</span>';
if ($meta) { $image = wp_get_attachment_image_src($meta, 'medium'); $image = $image[0]; }
echo '<input name="'.$field['id'].'" type="hidden" class="custom_upload_image" value="'.$meta.'" />
<img src="'.$image.'" class="custom_preview_image" alt="" /><br />
<input class="custom_upload_image_button button" type="button" value="Choose Image" />
<small> <a href="#" class="custom_clear_image_button">Remove Image</a></small>
<br clear="all" /><span class="description">'.$field['desc'].'</span>';
break;
} //end switch
echo '</td></tr>';
} // end foreach
echo '</table>'; // end table
}
// Save the Data
function save_multiBox_custom_meta($post_id) {
global $avz_custom_meta_box_fields;
// verify nonce
if (!wp_verify_nonce($_POST['avz_custom_meta_box_fields_nonce'], basename(__FILE__)))
return $post_id;
// check autosave
if (defined('DOING_AUTOSAVE') && DOING_AUTOSAVE)
return $post_id;
// check permissions
if ('page' == $_POST['post_type']) {
if (!current_user_can('edit_page', $post_id))
return $post_id;
} elseif (!current_user_can('edit_post', $post_id)) {
return $post_id;
}
// loop through fields and save the data
foreach ($avz_custom_meta_box_fields as $field) {
if($field['type'] == 'tax_select') continue;
$old = get_post_meta($post_id, $field['id'], true);
$new = $_POST[$field['id']];
if ($new && $new != $old) {
update_post_meta($post_id, $field['id'], $new);
} elseif ('' == $new && $old) {
delete_post_meta($post_id, $field['id'], $old);
}
} // enf foreach
// save taxonomies
$post = get_post($post_id);
$category = $_POST['category'];
wp_set_object_terms( $post_id, $category, 'category' );
}
add_action('save_post', 'save_multiBox_custom_meta');
在single.php中
if( $image_upload_id = get_post_meta($post->ID, $field['custom_image'], true)){
$img = $image_upload_id ['custom_image'][0];
echo wp_get_attachment_image($img, 'full');
}
但找不到附图。 在管理员上传的图片显示但在帖子页面没有显示。

您是否尝试过访问帖子附件?只是为了看它在那里?
<?php
$args = array(
'post_type' => 'attachment',
'numberposts' => null,
'post_status' => null,
'post_parent' => $post->ID
);
$attachments = get_posts($args);
if ($attachments) {
echo "<pre>";
print_r($attachments);
echo "</pre>";
$attachment = $attachments[0];
// print full link to attachment
the_attachment_link($attachment->ID, false);
}else{
echo "No Attachments for this post!";
}
?>
