我是php和wp插件开发新手，我刚刚为我的测试插件创建了一个简单的选项页面，选项页面只有一个复选框，我不知道如何在选中该复选框时执行一些功能，

我的插件选项页面如下

<?php

add_action( \'admin_menu\', \'chec_add_admin_menu\' );
add_action( \'admin_init\', \'chec_settings_init\' );


function chec_add_admin_menu(  ) { 

add_options_page( \'Checking\', \'Checking\', \'manage_options\', \'checking\', \'checking_options_page\' );

}


function chec_settings_init(  ) { 

register_setting( \'my_option\', \'chec_settings\' );

add_settings_section(
    \'chec_checking_section\', 
    __( \'Your section description\', \'wp\' ), 
    \'chec_settings_section_callback\', 
    \'checking\'
);

add_settings_field( 
    \'chec_checkbox_field_0\', 
    __( \'Settings field description\', \'wp\' ), 
    \'chec_checkbox_field_0_render\', 
    \'checking\', 
    \'chec_checking_section\' 
);


}


function chec_checkbox_field_0_render(  ) { 

$options = get_option( \'chec_settings\' );
?>
<input type=\'checkbox\' name=\'chec_settings[chec_checkbox_field_0]\' <?php checked( $options[\'chec_checkbox_field_0\'], 1 ); ?> value=\'1\'>
<?php

}

function chec_settings_section_callback(  ) { 

echo __( \'This section description\', \'wp\' );

}


function checking_options_page(  ) { 

?>
<form action=\'options.php\' method=\'post\'>

    <h2>Checking</h2>

    <?php
    settings_fields( \'my_option\' );
    do_settings_sections( \'checking\' );
    submit_button();
    ?>

</form>
<?php

}

?>

add_action( \'admin_bar_menu\', \'remove_wp_logo\', 999 );
function remove_wp_logo( $wp_admin_bar ) {
$wp_admin_bar->remove_node( \'wp-logo\' );
}
