I am writing a set of classes to easily create options pages accessible via submenus of the standard WordPress menus and a way to easily create options for said menus. The way I am wiring it is via a settings class which you pass settings to and I intend to have it work along with a submenu class to create the menu, settings page and store the options neatly in a single option. The option is getting created in the database -- but nothing is being stored in the option. Can anyone lead me in the right direction? Here is my code:
Settings Class
class settings_page {
public function __construct($args){
foreach($args['sections'] as $section){
$section_name = $section['section_name'];
$section_id = $section['section_id'];
if( false == get_option( $section_id ) ) {
add_option( $section_id );
}
$options = get_option($section_id);
$section_text = $section['section_text'];
$page = $section['page'];
add_settings_section($section_id, $section_name, function(){return $section_text;}, $page);
foreach($section['items'] as $item) {
$type = $item['type'];
$id = $item['id'];
$description = $item['description'];
$title = $item['title'];
$choices = $item['choices'];
if ($description) $title = $title . '<br /><small class="italic">' . $description . '</small>';
switch($type){
case "checkbox":
add_settings_field($id, $title,
function ($section) use ($options) {
$id = $section[0];
$html = '<input type="checkbox" id="' . $id . '" name="' . $id . '" value="1" ' . checked(1, $options[$id], false) . '/>';
echo $html;
},
$page, $section_id, array($id));
break;
case "text":
add_settings_field($id, $title,
function ($section) use ($options) {
$id = $section[0];
unset($html);
$html .= '<input type="text" id="' . $id . '" name="' . $id . '" value="' . $options[$id] . '" />';
echo $html;
},
$page, $section_id, array($id));
break;
case "textarea":
add_settings_field($id, $title,
function ($section) use ($options) {
$id = $section[0];
unset($html);
$html .= '<textarea class="large-text" cols="50" rows="10" type="text" id="' . $id . '" name="' . $id . '">' . $options[$id] . '</textarea>';
echo $html;
},
$page, $section_id, array($id));
break;
case "pulldown":
add_settings_field($id, $title,
function ($section) use ($options) {
$id = $section[0];
$choices = $section[1];
$value = $options[$id];
unset($html);
$html = '<select id="' . $id . '" name="' . $id . '">';
$html .= '<option value=""> - Select - </option>';
foreach($choices as $key=>$val){
$selected = '';
if ($value== $key) $selected = ' selected="selected" ';
$html .= '<option value="' . $key . '"' . $selected . '>'.$val.'</option>';
}
$html .= '</select>';
echo $html;
},
$page, $section_id, array($id, $choices));
break;
}
}
register_setting($page, $section_id);
}
new submenu(array(
"parent" => $args['parent'],
"title"=>$args['title'],
"text"=>$args['text'],
"capability"=>$args['capability'],
"slug"=>$args['slug']
));
}
}
Submenu Class
<?php
class submenu {
function __construct($args=""){
$parent = strtolower($args['parent']);
$title = $args['title'];
$text = $args['text'];
$capability = $args['capability'];
$slug = $args['slug'];
switch($parent){
case 'dashboard':
$name = "index.php";
break;
case 'posts':
$name = 'edit.php';
break;
case 'media':
$name='upload.php';
break;
case 'links':
$name='link-manager.php';
break;
case 'pages':
$name='edit.php?post_type=page';
break;
case 'comments':
$name='edit-comments.php';
break;
case 'appearance':
$name='themes.php';
break;
case 'plugins':
$name='plugins.php';
break;
case 'users':
$name='users.php';
break;
case 'tools':
$name='tools.php';
break;
case 'settings':
$name='options-general.php';
break;
default:
$name='options-general.php';
break;
}
add_action('admin_menu', function() use ($name, $title, $text, $capability, $slug) {
add_submenu_page(
$name,
$title,
$text,
$capability,
$slug, function() use ($name, $title, $text, $capability, $slug) {
?>
<div class="wrap">
<div id="icon-themes" class="icon32"></div>
<h2><?php echo $title; ?></h2>
<form method="post" action="options.php">
<?php settings_fields( $slug ); ?>
<?php do_settings_sections( $slug );?>
<?php submit_button(); ?>
</form>
</div>
<?php
}
);
}
);
}
}
Here is where I am actually calling the classes/methods
add_action('admin_menu',
function() {
$options['parent'] = "settings";
$options['title'] = "My Settings";
$options['text'] = "My Settings";
$options['capability'] = "manage_options";
$options['slug'] = "my_settings";
$settings['section_name'] = "General Section";
$settings['section_id'] = "general_section";
$settings['section_text'] = "This be General Section Test";
$settings['page'] = "my_settings";
$settings['items'] = array(
array(
'type' => 'checkbox',
'id' => 'show_header',
'title' => 'The title, to show header',
'description' => 'show the header now please',
),
array(
'type' => 'textarea',
'id' => 'show_footer',
'title' => 'The title, to show footer',
'description' => 'show the footer now please',
),
array(
'type' => 'text',
'id' => 'text_item',
'title' => 'Enter anything here',
'description' => '',
),
array(
'type' => 'pulldown',
'id' => 'which_one',
'title'=>'Who\'s on First?',
'description'=>'',
'choices'=>array(
'1'=>'Who',
'2'=>'What',
'3'=>'Why',
)
),
);
$settings2['section_name'] = "Second Section";
$settings2['section_id'] = "second_section";
$settings2['section_text'] = "More Settings";
$settings2['page'] = "my_settings";
$settings2['items'] = array(
array(
'type' => 'checkbox',
'id' => 'show_header_2',
'description' => 'Show Second Header',
'title' => 'Show the Second Header?',
),
array(
'type' => 'textarea',
'id' => 'show_footer_2',
'description' => 'Tell me a story',
'title' => 'It can be about anything!',
),
);
$options['sections'][] = $settings;
$options['sections'][] = $settings2;
new settings_page($options);
}, 1);
What works:
It works if I change $options[$id] to get_option($id) but this saves each individual setting to its own individual setting in the database which is wildly inefficient. I've error_logged $page, $section_id right before the register_setting call and everything is as it should be which leaves me baffled.
What doesn't work: saving these settings to a serialized array :)
I'm happy to provide anything else that can help you help me.
Thanks.
