php - WP Ajax not working in else condition -

i working on wordpress plugin. in plugin there check box, when user checked checkbox value saved in database via ajax , when unchecked value deleted database via ajax. create checkbox , write ajax code.

here code:

html code

<?php     $cart_items = get_cart_contents();      $cart_info = array();      foreach ($cart_items $_data) {         $prod_id = $_data['id'];          $cart_info[] = array(              'prod_id' => $prod_id,         );     }      $_cart_sr = serialize($cart_info);    ?>     <label class="label" for="purchase">          <?php _e('purchase', 'product'); ?>          <input type="checkbox" id="purchase" />     </label>      <input type="hidden" class="cart_info" value='<?php echo $_cart_sr; ?>'> 

here ajax , php code:

add_action('wp_ajax_values_save', 'save_check_value'); add_action('wp_ajax_nopriv_values_save', 'save_check_value'); add_action('wp_ajax_values_delete', 'delete_check_value'); add_action('wp_ajax_nopriv_values_delete', 'delete_check_value');  add_action("wp_head", "edd_gift_email_ajax"); function edd_gift_email_ajax() {     ?>     <script type="text/javascript">         jquery(document).ready(function () {             jquery("#purchase").click(function () {                 if(jquery(this).is(":checked")) {                     var cart_info_save = jquery('.cart_info').val();                      var data_save = {                         action: 'values_save',                         cart_info_save: cart_info_save                     }                      jquery.post('<?php echo admin_url('admin-ajax.php'); ?>', data_save, function (save_result) {                         alert(save_result);                     });                 } else {                     var cart_info_delete = jquery('.cart_info').val();                      var data_delete = {                         action: 'values_delete',                         cart_info_delete: cart_info_delete                     }                      jquery.post('<?php echo admin_url('admin-ajax.php'); ?>', data_delete, function (delete_result) {                         alert(delete_result);                     });                 }             });         });     </script>     <?php } 

and here save , delete query

function save_check_value() {     global $wpdb;      $info_save = stripcslashes($_request['cart_info_save']);      $cart_info_un_sr_save = unserialize($info_save);      foreach ($cart_info_un_sr_save $user_gift_cart_save) {         $prod_user_id_save = $user_cart_save['prod_id'];          echo $prod_user_id_save . " _ add this";          //update_post_meta($prod_user_id_save, 'this_product', '1');     } }  function delete_check_value() {     global $wpdb;      $info_delete = stripcslashes($_request['cart_info_delete']);      $cart_info_un_sr_delete = unserialize($info_delete);      foreach ($cart_info_un_sr_delete $user_cart_delete) {         $prod_user_id_delete = $user_cart_delete['prod_id'];          echo $prod_user_id_delete . " _ delete this";          //delete_post_meta($prod_user_id_delete, 'this_product', '1');     } } 

so when checked check box alert gives me value 168 _ add this (this want) when unchecked check box alert gives me value 0 (i want value 168 _ delete this).

i checked every thing got confused why else condition not give me right value.

any suggestions.

the answer of @ramraider can still reduce more code , might work :)

here's jquery:

<script type="text/javascript">     jquery(document).ready(function() {         jquery("#purchase").click( function() {              // method variable using define              // function should trigger later in our php             var cart_method = jquery(this).is(":checked") ? 'save' : 'delete';              var cart_info = jquery('.cart_info').val();              var data = {                 action: 'modify_cart',                 cart_method: cart_method,                 cart_info: cart_info             };              jquery.post('<?php echo admin_url('admin-ajax.php'); ?>', data, function( result ) {                     alert( result );                 });             }         });     }); </script> 

and here our php code:

<?php     function modify_cart_func() {         global $wpdb;          // method our jquery         $method = $_post['cart_method'];          $info = stripcslashes( $_request['cart_info'] );         $cart_info = unserialize( $info );          foreach( $cart_info $gift ) {             // if method save            if ($method == 'save') {                 update_post_meta($gift['product_id'], 'this_product', 1);             // if method delete            } else if ($method == 'delete') {                 delete_post_meta($gift['product_id'], 'this_product', 1);             }          }     } ?> 

and ajax call:

<?php add_action('wp_ajax_modify_cart', 'modify_cart_func'); add_action('wp_ajax_nopriv_modify_cart', 'modify_cart_func'); ?> 

hope makes sense ;)
