Get select value to module PHP

[cikcak]

Hey,

 

Briefly, I would like to get value of select input and save it to my module php file. I need to save it to use it in other page.

 

Mymodule.tpl:

<select id="gr">
   <option selected="selected">-</option>
   <option value="2">two</option>
   <option value="4">four</option>
 </select> 

js/mymodule.js content:

$( document ).ready(function() {
    $('#gr').on('change', fixValue);
});

function fixValue() {
    which =  $('select#gr option:selected').val();
       $("#rez").text(gr);
       
  $.ajax({
  type: 'POST',
  url: baseDir + 'modules/mymodule/ajax.php',
  data: 'method=myMethod&id_data=' + $('select#gr option:selected').val(),
  dataType: 'json',
  success: function(json) {
       alert("ok");
  }
});      

}  

So this ajax.php file content:

<?php
require_once(dirname(__FILE__).'../../../config/config.inc.php');
require_once(dirname(__FILE__).'../../../init.php');
switch (Tools::getValue('method')) {
  case 'myMethod' :
    die( Tools::jsonEncode( array('result'=>'my_value'));
    break;
  default:
    exit;
}
exit;

?>

First of all, I don`t see alert so why it not works? And second question, how should I use that value in mymodule.php?

Thanks for any help!

 $('#gr').change(function(){
    //Call ajax here
});

You are not calling the function correctly

Okey, thanks, but I can`t find any information how to get value in my module php. Should I use controller or what? Ill try this! Thanks!

If you check Chrome's "Inspect element"  - do you see one request fired for baseDir + 'modules/mymodule/ajax.php' when changing the selected option?

If yes, what is the request status code?

You must use your main php file. The one that defines your module. I dont know how to process it further

check browser console.

ctrl+shift+j in chrome

open "network" tab

and see headers ($_POST values) of your ajax request

 

does it push correct params?

you can use any other .php file inside in the module and there is no need to use it as a controller
