I am developing a plugin in which Ajax is not working. I'm using this code:

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

The edit_added_people() function is not called after calling the action cpm_add_update, what could be the reason for this?

Here is my code for the form:

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';

    <div class="cpm-milestone-form-wrap" id="add_people-form">
        <h3 style="background: none repeat scroll 0 0 #ccc; color: #222;font-size: 1.3em; margin: -0.5em -0.5em 2em;padding: 12px; text-align: center; width: 579px;"><?php _e('User Detail Form ', 'cpm'); ?></h3>
        <form class="cpm-add-people-form" action="" method="post" id="cpm-user-edit-here">
            <table  cellspacing="0" cellpadding="5">

                <?php if (!is_null($people)) {

                $first_name = get_user_meta($people->ID, 'first_name', true);} ?>

                <?php if (!is_null($people)) {
                $last_name = get_user_meta($people->ID, 'last_name', true);} ?>
                    <td><b>Last Name : </b></td><td><input name="people_last_name" style="width:100%;" type="text" id="people_last_name" value="<?php echo esc_attr($last_name); ?>"></td>

                    <td><b>Role : </b></td><td><select name="role" id="role" class="required cpm-jitender" style="width:50%;">
                           $current_role = $people->roles[0] ;
                            if (!$new_user_role)
                                $new_user_role = !empty($current_role) ? $current_role : get_option('default_role');
            <div class="cpm-attachment"> <?php cpm_upload_userimg_field($id, $files); ?></div>

            <?php do_action('cpm_add_people_form', $project_id, $people); ?>
            <div class="submit">
                <input type="hidden" name="action" value="<?php echo $action; ?>" />
                <input type="hidden" name="project_id" value="<?php echo $project_id; ?>" />

                <?php if ($id) { ?>
                    <input type="hidden" name="people_id" value="<?php echo $id; ?>" />
                <?php } ?>

                <input type="submit" name="create_new_people" id="create_new_people" class="button-primary" value="<?php echo esc_attr($submit); ?>">
                <a id="CancleButton" class="button add-people-cancel" href="#"><?php _e('Cancel', 'cpm'); ?></a>

    return ob_get_clean();

After this on ajax.php:

add_action( 'wp_ajax_nopriv_cpm_add_update', array( $this, 'edit_added_people' ) );    
function edit_added_people() {
        $posted = $_POST;
    $people_id= $posted['people_id'];
        $people_obj = CPM_People::getInstance();
        $added_user_id = $people_obj->Add_user_update($people_id);
        if ($added_user_id) {
            $response = array(
                'success' => true,
                'id' => $added_user_id,
                'content' => cpm_task_html($task, $project_id, $list_id),
        } else {
            $response = array('success' => false);
        echo json_encode($response);
  • Have you added the code in your plugin's main file?

if the request is from an unauthenticated user, you should use wp_ajax_nopriv_(action) to call the function, which in your case is:

add_action('wp_ajax_nopriv_cpm_add_update', array($this,'edit_added_people'));
  • still not solved my problem. it is reloading the page in spite of calling edit_added_people() Aug 10, 2015 at 13:30
  • can you post more code?

  • @Rahul, if it's reloading the page, this means you might have issue in your JS code, either there is problem in JS code or you haven't added code to prevent from page load
