Ich entwickle ein Plugin, das das Boilerplate- Repository von Tom McFarlin als Vorlage verwendet und OOP-Praktiken verwendet. Ich habe versucht, genau herauszufinden, warum ich meine Einstellungen nicht korrekt übermitteln kann. Ich habe versucht, das Aktionsattribut auf eine leere Zeichenfolge zu setzen, wie in einer anderen Frage hier vorgeschlagen, aber das hat nicht geholfen ...
Unten ist das allgemeine Code-Setup, das ich verwende ...
Das Formular (/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>
Nehmen Sie für den folgenden Code an, dass alle Rückrufe für add_settings_field () und add_settings_section () vorhanden sind, mit Ausnahme von 'option_list_selection'.
Die Plugin Admin Klasse (/ {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
);
}
}
Einige angeforderte Updates:
Ändern des Aktionsattributs in:
<form action="../../options.php" method="post">
... führt einfach zu einem 404-Fehler. Das Folgende ist der Auszug aus den Apache-Protokollen. Beachten Sie, dass die Standard-WordPress-Skripte und CSS-Warteschlangen entfernt werden:
