Je développe un plugin en utilisant le référentiel Boilerplate de Tom McFarlin comme modèle, qui utilise les pratiques de POO. J'ai essayé de comprendre exactement pourquoi je ne pouvais pas soumettre correctement mes paramètres. J'ai essayé de définir l'attribut action sur une chaîne vide comme suggéré dans une autre question ici, mais cela n'a pas aidé ...
Voici la configuration générale du code que j'utilise ...
Le formulaire (/views/admin.php):
<div class="wrap">
<h2><?php echo esc_html( get_admin_page_title() ); ?></h2>
<form action="options.php" method="post">
<?php
settings_fields( $this->plugin_slug );
do_settings_sections( $this->plugin_slug );
submit_button( 'Save Settings' );
?>
</form>
</div>
Pour le code suivant, supposez que tous les rappels pour add_settings_field () et add_settings_section () existent, à l'exception de 'option_list_selection'.
La classe Admin du plugin (/ {plugin_name} -class-admin.php):
namespace wp_plugin_name;
class Plugin_Name_Admin
{
/**
* Note: Some portions of the class code and method functions are missing for brevity
* Let me know if you need more information...
*/
private function __construct()
{
$plugin = Plugin_Name::get_instance();
$this->plugin_slug = $plugin->get_plugin_slug();
$this->friendly_name = $plugin->get_name(); // Get "Human Friendly" presentable name
// Adds all of the options for the administrative settings
add_action( 'admin_init', array( $this, 'plugin_options_init' ) );
// Add the options page and menu item
add_action( 'admin_menu', array( $this, 'add_plugin_admin_menu' ) );
}
public function add_plugin_admin_menu()
{
// Add an Options Page
$this->plugin_screen_hook_suffix =
add_options_page(
__( $this->friendly_name . " Options", $this->plugin_slug ),
__( $this->friendly_name, $this->plugin_slug ),
"manage_options",
$this->plugin_slug,
array( $this, "display_plugin_admin_page" )
);
}
public function display_plugin_admin_page()
{
include_once( 'views/admin.php' );
}
public function plugin_options_init()
{
// Update Settings
add_settings_section(
'maintenance',
'Maintenance',
array( $this, 'maintenance_section' ),
$this->plugin_slug
);
// Check Updates Option
register_setting(
'maintenance',
'plugin-name_check_updates',
'wp_plugin_name\validate_bool'
);
add_settings_field(
'check_updates',
'Should ' . $this->friendly_name . ' Check For Updates?',
array( $this, 'check_updates_field' ),
$this->plugin_slug,
'maintenance'
);
// Update Period Option
register_setting(
'maintenance',
'plugin-name_update_period',
'wp_plugin_name\validate_int'
);
add_settings_field(
'update_frequency',
'How Often Should ' . $this->friendly_name . ' Check for Updates?',
array( $this, 'update_frequency_field' ),
$this->plugin_slug,
'maintenance'
);
// Plugin Option Configurations
add_settings_section(
'category-option-list', 'Widget Options List',
array( $this, 'option_list_section' ),
$this->plugin_slug
);
}
}
Quelques mises à jour demandées:
Modification de l'attribut d'action en:
<form action="../../options.php" method="post">
... entraîne simplement une erreur 404. Ce qui suit est l'extrait des journaux Apache. Notez que les scripts WordPress et les files d'attente CSS par défaut sont supprimés:
