我正在开发一个Ajax不起作用的插件。我正在使用以下代码：

add_action( \'wp_ajax_cpm_add_update\', array( $this, \'edit_added_people\' ) ); 

以下是我的表单代码：

function cpm_add_people_form( $project_id, $people = null ) {    
    $title = $content = \'\';
    $submit = __( \'Add Person\', \'cpm\' );
    $users = array();
    $id = $milestone = 0;
    $action = \'cpm_add_user_new\';   
    if ( !is_null( $people ) ) {
        $id = $people->ID;
        $title = $people->post_title;
        $name = $people->display_name;
        $email = $people->user_email;
        $files = array();
        $users = empty( $project->users ) ? array() : $project->users;
        $submit = __( \'Update New People\', \'cpm\' );
        $action = \'cpm_add_people_update\';
    }   
    ob_start();
    ?>
