функция Ajax не получает никакого ответа от функции CakePHP caontroller

Question

У меня есть функция JQuery, как показано ниже:

$(document).ready(function() { 
    get_search_results(); 
}); 

function get_search_results() { 
    //get the selected location_id 

    var gal_location_id = 0; 


    //get the selected package 
    var starting_package_wedding = 1; 

    var data = "gal_location_id="+gal_location_id+"&starting_package_wedding="+starting_package_wedding; 

    var url_to_call = "http://localhost/myshaadi/gal_providers/api_search"; //No alerts 
    //var url_to_call = "http://localhost/myshaadi/photographers/gen_uid"; //Alerts 

    $.ajax({ 
     type: "GET", 
     url: url_to_call, 
     // async: false, 
     //dataType: "json", 
     data: data, 
     error:function(resp){ 

     }, 
     success: function(resp){ 
      alert(resp); 
      //render_search_result(resp); 
     } 
    }); 
} 

И контроллер gal_providers функцию api_search() является:

function api_search() { 
return 'Hello'; 
} 

Но страница ничего не предупредит. также, если я изменяю переменную url_to_call на другую функцию контроллера, она предупреждает! Итак, я хочу знать, что такое ошибка?

EDIT: search.ctp

<style> 
#search_filters{ 
    border: 1px solid silver; 
    line-height: 22px; 
} 
#search_filters .header{ 
    background-color: orange; 
    padding: 5px; 
    margin-bottom: 10px; 
} 
</style> 
<script> 

$(document).ready(function() { 
    get_search_results(); 
}); 

function get_search_results() { 
    //get the selected location_id 

    var gal_location_id = 0; 


    //get the selected package 
    var starting_package_wedding = 1; 

    var data = "gal_location_id="+gal_location_id+"&starting_package_wedding="+starting_package_wedding; 

    var url_to_call = "http://localhost/myshaadi/gal_providers/api_search"; //No alerts 
    //var url_to_call = "http://localhost/myshaadi/photographers/gen_uid"; //Alerts 
    $.ajax({ 
     type: "GET", 
     url: url_to_call, 
     // async: false, 
     //dataType: "json", 
     data: data, 
     error:function(resp){ 

     }, 
     success: function(resp){ 
      alert(resp); 
      //render_search_result(resp); 
     } 
    }); 
}

Answer 1

использование эхо вместо возвращения в вашей функции api_search() и попробовать.

api_search() { 
echo 'Hello'; 
} 

Answer 2

function api_search() { 
echo "Hello"; 
exit; 
}
