如何获取此项以保存单选按钮？它可以保存复选框，但我尝试了很多方法，但无法保存径向按钮。任何帮助都将不胜感激。
工作插件示例只需放入wp-content/plugins/myplug文件夹。
<?php
/*
Plugin Name: myplug

add_action(\'admin_init\', \'myplug_register_options\'); // register options for the form
add_action(\'admin_menu\', \'myplug_admin_links\'); // register admin menu hyperlinks
/** Function to register form fields **/
function myplug_register_options(){
register_setting(\'myplug_options_group\', \'myplug_settings\', \'myplug_validate\');
}
/** Function to add hyperlinks to the admin menus using hooks and filters. **/
function myplug_admin_links() {
add_options_page(\'myplug Setup\', \'myplug\', \'manage_options\', \'myplug\', \'myplug_admin_page\' ); // add link to settings page
add_filter( \'plugin_action_links\', \'myplug_settings_link\', 10, 2 ); // add link to plugin page
}
/** Function to create link for plugin_action_links filter **/
function myplug_settings_link($links, $file){
if ( $file == plugin_basename( dirname(__FILE__). \'/myplug.php\')){
$settings_link = \'<a href="options-general.php?page=myplug">\' .__(\'Settings\') . \'</a>\';
array_unshift( $links, $settings_link ); // place before other links
}
return $links;
}
/** Validate User Input **/
function myplug_validate($input) {
$input[\'value1\'] = wp_filter_nohtml_kses($input[\'value1\']);
$input[\'value2\'] = wp_filter_nohtml_kses($input[\'value2\']);
$input[\'select_display\'] = wp_filter_nohtml_kses($input[\'select_display\']);
return($input);
}
/** Draw the Settings Page **/

您发布的代码中有一些错误，可能只是输入错误，通常输入的名称与相关设置的名称不匹配。
将设置保存为数组时，名称必须始终位于表单中array_name[\'option_name\'] 但对于收音机，你不遵守这个规则（但对于其他领域，你会遵守）。
使用你的代码我只更改了myplug_validate 和myplug_admin_page 具有以下功能：
function myplug_validate($input) {
return array_map(\'wp_filter_nohtml_kses\', (array)$input);
}
function myplug_admin_page() { ?>
<div>
<h2>Options</h2>
<form method="post" action="options.php">
<?php
settings_fields(\'myplug_options_group\');
$myplug_options = get_option(\'myplug_settings\');
?>
<input type="checkbox" name="myplug_settings[checkbox1]" value="1" <?php checked(\'1\', $myplug_options[\'checkbox1\']); ?> /><br />
<input type="text" class="regular-text" name="myplug_settings[text1]" value="<?php echo $myplug_options[\'text1\']; ?>" /><br />
<input type="checkbox" name="myplug_settings[checkbox2]" value="1" <?php checked(\'1\', $myplug_options[\'checkbox2\']); ?> /><br />
<input type="text" class="regular-text" name="myplug_settings[text2]" value="<?php echo $myplug_options[\'text2\']; ?>" /><br />
<input type="radio" name="myplug_settings[radio1]" value="item1" <?php checked(\'item1\', $myplug_options[\'radio1\']); ?> /><br />
<input type="radio" name="myplug_settings[radio1]" value="item2" <?php checked(\'item2\', $myplug_options[\'radio1\']); ?> /><br />
<?php submit_button(); ?>
</form>
</div>
<?php } ?>
我已经测试过了，效果很好。
