Problèmes avec la sauvegarde de metabox
J'avais donc quelques métaboxes, qui étaient mal étiquetées (meta_1, meta_2) et je les ai renommées pour les rendre plus faciles à comprendre pour la maintenance.
Lorsque je suis retourné voir comment d'autres utilisateurs développaient des métaboxes, j'ai trouvé ce style de création:
// Review field array
$prefix_review = 'meta_review_';
$meta_review_information_array = array(
array(
'label' => 'Single checkbox',
'id' => $prefix_review . 'checkbox',
'class' => '',
'type' => 'checkbox'
),
array(
'label'=> 'Number input',
'desc' => '',
'id' => $prefix_review . 'number',
'class' => '',
'min' => '1900',
'max' => '2100',
'step' => '1',
'type' => 'number'
),
array(
'label' => 'Text input',
'desc' => '',
'id' => $prefix_review . 'text',
'class' => '',
'type' => 'text'
),
array (
'label' => 'Checkbox group',
'desc' => '',
'id' => $prefix_review . 'checkboxes',
'class' => '',
'type' => 'checkbox_group',
'options' => array (
'one' => array ( 'label' => 'Label one', 'value' => 'one' ),
'two' => array ( 'label' => 'Label two', 'value' => 'two' ),
'three' => array ( 'label' => 'Label three', 'value' => 'three' )
)
),
array (
'label' => 'Dropdown',
'desc' => '',
'id' => $prefix_review . 'dropdown',
'class' => '',
'type' => 'select',
'options' => array (
'one' => array ( 'label' => 'Label one', 'value' => 'one' ),
'two' => array ( 'label' => 'Label two', 'value' => 'two' )
)
),
)
// Project field array
$prefix_project = 'meta_project_';
$meta_project_information_array = array(
array(
'label' => 'Single checkbox',
'id' => $prefix_project . 'checkbox',
'class' => '',
'type' => 'checkbox'
),
array(
'label'=> 'Number input',
'desc' => '',
'id' => $prefix_project . 'number',
'class' => '',
'min' => '1900',
'max' => '2100',
'step' => '1',
'type' => 'number'
),
array(
'label' => 'Text input',
'desc' => '',
'id' => $prefix_project . 'text',
'class' => '',
'type' => 'text'
),
array (
'label' => 'Checkbox group',
'desc' => '',
'id' => $prefix_project . 'checkboxes',
'class' => '',
'type' => 'checkbox_group',
'options' => array (
'one' => array ( 'label' => 'Label one', 'value' => 'one' ),
'two' => array ( 'label' => 'Label two', 'value' => 'two' ),
'three' => array ( 'label' => 'Label three', 'value' => 'three' )
)
),
array (
'label' => 'Dropdown',
'desc' => '',
'id' => $prefix_project . 'dropdown',
'class' => '',
'type' => 'select',
'options' => array (
'one' => array ( 'label' => 'Label one', 'value' => 'one' ),
'two' => array ( 'label' => 'Label two', 'value' => 'two' )
)
),
)
Et la sortie dans la metabox est facile à suivre avec un $switch['type'] puis en bouclant la classe de tableau (par exemple $meta_project_information_array).
Quand je vais le sauver cependant, je suis perplexe.
D'abord je fais:
add_action('save_post', '_save_metabox');
// Save the Data
function _save_metabox( $post_id ) {
global $meta_review_information_array, $meta_project_information_array;
// 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 and save : review
foreach( $meta_review_information_array as $meta_review_info ) {
$meta_review_info_old = get_post_meta($post_id, $meta_review_info['id'], true);
$meta_review_info_new = $_POST[$field_1['id']];
if( $meta_review_info_new && $meta_review_info_new != $meta_review_info_old ) {
update_post_meta( $post_id, $meta_review_info['id'], $meta_review_info_new );
} elseif( '' == $meta_review_info_new && $meta_review_info_old ) {
delete_post_meta($post_id, $meta_review_info['id'], $meta_review_info_old);
}
}
// Loop and save: project
foreach( $meta_project_information_array as $meta_project_info ) {
$meta_project_info_old = get_post_meta($post_id, $meta_project_info['id'], true);
$meta_project_info_new = $_POST[$field_1['id']];
if( $meta_project_info_new && $meta_project_info_new != $meta_project_info_old ) {
update_post_meta( $post_id, $meta_project_info['id'], $meta_project_info_new );
} elseif( '' == $meta_project_info_new && $meta_project_info_old ) {
delete_post_meta($post_id, $meta_project_info['id'], $meta_project_info_old);
}
}
}
Je suppose que mes questions sont les suivantes: 1. Pourquoi les informations ci-dessus ne sont-elles pas sauvegardées lorsque je saisis les données? 2. Comment puis-je ajouter le nonce à la section de sauvegarde? Chaque metabox a-t-il un nonce distinct ou est-il identique? Certains CPT ont plus d'une metabox. 3. Y a-t-il une meilleure façon de s'y prendre?
Pour le moment j'ai 3 fichiers php:
admin_column.php //this is the admin columns in the CPT
metabox.php //which has all the $types for the many metaboxes and the <table>
save_metabox.php //which is the saving of the metabox
There are different ways of saving the metaboxes.
for e.g. you can create 2 files
1) test-spec.php
2) test-meta.php
Dans le fichier test-spec.php
<?php
//DEFINE VARIABLE TO STORE THE METABOX
$content_test_meta = new WPAlchemy_MetaBox(array
(
'id' => '_content_test_meta', //UNIQUE ID FOR THIS META BOX
'types' => array('post'), //LIMIT TO ONLY SHOW ON Default POST TYPE
'template' => get_stylesheet_directory() . '/metaboxes/test-meta.php' //WHERE THE METABOX TEMPLATE IS FOR THIS METABOX
));
?>
Dans le fichier test-meta.php
Supposons que je veuille sauvegarder le champ de texte
<?php global $wpalchemy_media_access; ?>
<div class="my_meta_control metabox">
<label>Text Box</label>
<?php $metabox->the_field('text_box'); /* SET THE FIELD ID */ ?>
<p><input type="text" name="<?php $metabox->the_name(); /* SET THE INPUT NAME TO THE FIELD ID */ ?>" value="<?php $metabox->the_value(); /* SET THE INPUT VALUE TO THE FIELD VALUE */ ?>" class="wp-editor-area" /></p>
</div>
