Lavorando con metabox / campi personalizzati mi è sembrato di creare indirettamente molti di questi in _encloseme
meta_keys
tutto il mio wp_postmeta
.
Visto qui:
Finora non sono sorti problemi da questo e i campi personalizzati funzionano bene, ma ho solo agitato con circa 2 post sul mio sito di test locale e non voglio implementarlo sul mio sito live se causerà problemi in seguito lungo la strada. Qualcuno sa cosa fare al riguardo, sono normali?
Ecco il codice per i miei metabox.
<?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;
}
//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 $post_id;
}
foreach ($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 id applied to the meta box
'id' => 'venue_location',
//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(
'name' => 'Venue',
'desc' => 'Venue Name',
'id' => 'venue_info',
'type' => 'text',
'default' => ''
),
array(
'name' => 'Location',
'desc' => 'Location of the Venue',
'id' => 'location_info',
'type' => 'text',
'default' => ''
)
)
);
add_action('admin_menu', 'plib_add_box');
