将变量从javascript传递到php

Question

I'm trying to pass a variable from a js function to php form (in the same file). Here is my form :

 <div id="hoursDetails" class="toogle_form" style="display:none">
      <table border=0>
            <?php
                 for ($i=0 ; $i<$N; $i++){ //$N is the variable I want to retrieve
                 echo '<tr>
            <td><div id="date'.$i.'" ></div></td>   
            <td>
             <input type=text name="action'.$i.'"  placeholder="Votre action"/>
             <input type="text" name="temps'.$i.'"  placeholder="nombre heures"/>
            </td>
                </tr> ';}
              ?>
      </table>
</div>

I tried to create a hidden input in the form :

<input type="hidden" id="variable" name="variable" value="" >

And to set the value from the js function using $('#variable').val(10) for example, but still don't know how to retrieve this variable when looping. I can retrieve this variable from the controller, but is it possible to pass it from controller to the view without using index() function? (I'm using CodeIgniter Could anyone help me please ? Thanks

You can't pass a variable from Js to PHP without making a request. Condiser that PHP is evaluated on server side, then when rendering on client side, Javascript triggers. If you need to pass a value from Js to PHP, you should try to use Ajax.
