Notice: Use of undefined constant KCVT_URL

  • Farhan Sabir


    I installed and activated the plugin. Getting the following error:

    Notice: Use of undefined constant KCVT_URL – assumed ‘KCVT_URL’ in …../public_html/blog/wp-content/plugins/gc-testimonials/testimonials.php on line 946

    line 944-947:

    if ( is_admin() ) {
    	//register_uninstall_hook(KCVT_URL.'/testimonials.php', 'gct_testimonials_de_register_settings');
    	register_activation_hook(KCVT_URL.'/testimonials.php', 'gct_testimonials_register_settings');

    Can you please help?

    On front-end using shortcode [full-testimonials]</strong] I have two notices:

    Notice: Undefined variable: wp_query in ...../public_html/blog/wp-content/plugins/gc-testimonials/testimonials.php on line 500
    Notice: Undefined variable: display in ...../public_html/blog/wp-content/plugins/gc-testimonials/testimonials.php on line 505

    line 949: change KCVT_URL to GCT_URL

    comment out lines 445, 502, 764: // $temp = $wp_query;

    lines 351 and 507: change $display .= to $display = (without the period)

    Thanks for the help.

    You have solved most of the problems, but when I try to use the shortcode [testimonial-form], I get “undefined variable” for all the variables ($error, etc.) on line 621:

    return gct_get_create_testimonial_form($error, $success, $gct_client_name, $gct_email, $gct_company_name, $gct_company_website, $gct_headline, $gct_text, $gct_agree, $gct_client_photo);

    Can you see a fix for this one?


    You’re welcome.

    I reworked the code enough that it will be easier to just replace the entire section. My apologies to the original developer if I’m overstepping.

    function gct_form_shortcode($atts) {
      global $add_styles, $add_validation;
      $add_styles = true;
      $add_validation = true;
      if (isset( $_POST['gct_create_testimonial_form_submitted'] )
          && wp_verify_nonce( $_POST['gct_create_testimonial_form_submitted'], 'gct_create_testimonial_form' ) ) {
        $gct_client_name = trim($_POST['gct_client_name']);
        $gct_email = trim($_POST['gct_email']);
        $gct_company_name = trim($_POST['gct_company_name']);
        $gct_company_website = trim($_POST['gct_company_website']);
        $gct_headline = trim($_POST['gct_headline']);
        $gct_text = trim($_POST['gct_text']);
        $gct_agree = trim($_POST['gct_agree']); 
        $testimonial_data = array(
          'post_title' => $gct_headline,
          'post_content' => $gct_text,
          'post_status' => 'pending',
          'post_type' => 'testimonial'
        if ($testimonial_id = wp_insert_post($testimonial_data)) {
          add_post_meta($testimonial_id, "client_name", $gct_client_name);
          add_post_meta($testimonial_id, "email", $gct_email);

          add_post_meta($testimonial_id, "company_website", $gct_company_website);
          if($_FILES['gct_client_photo']['size'] > 1) {
            foreach($_FILES as $field => $file) {
              // Upload File
              $overrides = array('test_form' => false);
              $uploaded_file = gct_wp_handle_upload($_FILES['gct_client_photo'], $overrides);
              $gct_client_photo = $uploaded_file['url'];

              $attachment = array(

                'post_parent' => $testimonial_id,
                'post_mime_type' => $file['type'],
                'guid' => $uploaded_file['url']
              $attach_id = wp_insert_attachment( $attachment, $uploaded_file['file'], $testimonial_id );
              $attach_data = wp_generate_attachment_metadata( $attach_id, $uploaded_file['file'] );
              wp_update_attachment_metadata( $attach_id,  $attach_data );
              add_post_meta($testimonial_id, 'client_photo', $gct_client_photo);
              set_post_thumbnail( $testimonial_id, $attach_id );
          $email_me = get_option('att_email_me');
          $email_address = get_option('att_email_address');
          if($email_me == 'yes' && $email_address != '') {
            $to = $email_address;

    Chris: You’re the best! All works now. I can’t believe you did all this work to fix this. I hope the author builds this fix into his code.

    I can’t wait to read through your code and compare it to the original to see what you did to fix it.

    Thanks again.


    Do you have the entire fixed GC Testimonials plugin package you might be able to send me? I’m having the same issue.


    Sorry robertrhu, I wasn’t monitoring this thread. Contact me at chris at wpmission dot com. I’m actually working on a fork of this plugin that you may be interested in; that should be ready in January.


    Michael Cannon says he has fixed the errors:
