En travaillant avec des métaboxes / champs personnalisés, j'ai semblé en créer indirectement un grand nombre _encloseme
meta_keys
partout sur mon site wp_postmeta
.
Vu ici:
Jusqu'à présent, aucun problème n'est survenu et les champs personnalisés fonctionnent bien, mais je ne me suis occupé que de 2 publications sur mon site de test local et je ne veux pas l'implémenter sur mon site en direct si cela devait causer des problèmes plus tard. sur la route. Quelqu'un sait quoi faire à ce sujet, est-ce normal?
Voici le code de mes métaboxes.
<?php
//Add meta boxes to post types
function plib_add_box() {
global $meta_box;
foreach($meta_box as $post_type => $value) {
add_meta_box($value['id'], $value['title'], 'plib_format_box', $post_type, $value['context'], $value['priority']);
}
}
//Formatting
function plib_format_box() {
global $meta_box, $post;
// verification
echo '<input type="hidden" name="plib_meta_box_nonce" value="', wp_create_nonce(basename(__FILE__)), '" />';
echo '<table class="form-table">';
foreach ($meta_box[$post->post_type]['fields'] as $field) {
// get current post meta data
$meta = get_post_meta($post->ID, $field['id'], true);
echo '<tr>'.
'<th style="width:20%"><label for="'. $field['id'] .'">'. $field['name']. '</label></th>'.
'<td>';
switch ($field['type']) {
case 'text':
echo '<input type="text" name="'. $field['id']. '" id="'. $field['id'] .'" value="'. ($meta ? $meta : $field['default']) . '" size="30" style="width:97%" />'. '<br />'. $field['desc'];
break;
case 'textarea':
echo '<textarea name="'. $field['id']. '" id="'. $field['id']. '" cols="60" rows="4" style="width:97%">'. ($meta ? $meta : $field['default']) . '</textarea>'. '<br />'. $field['desc'];
break;
case 'select':
echo '<select name="'. $field['id'] . '" id="'. $field['id'] . '">';
foreach ($field['options'] as $option) {
echo '<option '. ( $meta == $option ? ' selected="selected"' : '' ) . '>'. $option . '</option>';
}
echo '</select>';
break;
case 'radio':
foreach ($field['options'] as $option) {
echo '<input type="radio" name="' . $field['id'] . '" value="' . $option['value'] . '"' . ( $meta == $option['value'] ? ' checked="checked"' : '' ) . ' />' . $option['name'];
}
break;
case 'checkbox':
echo '<input type="checkbox" name="' . $field['id'] . '" id="' . $field['id'] . '"' . ( $meta ? ' checked="checked"' : '' ) . ' />';
break;
}
echo '<td>'.'</tr>';
}
echo '</table>';
}
// Save data from meta box
function plib_save_data($post_id) {
global $meta_box, $post;
//Verify
if (!wp_verify_nonce($_POST['plib_meta_box_nonce'], basename(__FILE__))) {
return $post_id;
}
//Check > autosave
if (defined('DOING_AUTOSAVE') && DOING_AUTOSAVE) {
return $post_id;

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 $post_id;
}
foreach ($meta_box[$post->post_type]['fields'] as $field) {
$old = get_post_meta($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);
}
}
}
add_action('save_post', 'plib_save_data');
//We create an array called $meta_box and set the array key to the relevant post type
// If custom post type, change the 'post' variable
$meta_box['post'] = array(

//This is the title that appears on the meta box container
'title' => 'Venue/Location',
//This defines the part of the page where the edit screen section should be shown
'context' => 'normal',
//This sets the priority within the context where the boxes should show
'priority' => 'high',
//Here we define all the fields we want in the meta box
'fields' => array(
array(

'default' => ''
