$ _POST没有在PHP中返回任何内容

Question

I have _header.tpl inside inc folder here is full path C:\\WebServerN\\home\\localhost\\www\\e-test.ru\\inc\\templates\\default_header.tpl Inside _header.tpl I added

    <td width="85%" align=right class=top_section> 
              <form action="init.inc.php" method='post'>
              <select name="switchlanguage" id="switchlanguage"> 
              <option value="en" >English</option>
              <option value="ru" >Русский</option>
              <option value="tj" >Точики</option> 
              </select> 
        </form>
        </td>  

In order to make dropdown listbox for language switching. What I want is to get "en", "ru", "tj" if they are chosen. I have init.inc.php here is full path C:\\WebServerN\\home\\localhost\\www\\e-test.ru\\inc\\init.inc.php I want to switch code according to chosen value. Here is my code in init.inc.php

if(!isset($_POST['switchlanguage']))
  {
  include_once($DOCUMENT_LANG.'en.lng.php');
  }
  else
  {
  include_once($DOCUMENT_LANG.$_POST['switchlanguage'].'.lng.php');
  }

I am new in PHP, I need your help. Please give me some direction or will be better if you provide me some codes. Thanks.

Answer 1

The problem was I did not have submit button. In order to get $_POST I need somehow submit the form. So I could not use button due to design issues. I used auto submit. Here is my code.

<td width="85%" align=right class=top_section> 
          <form  method='post'>
          <select name="switchlanguage" onchange="this.form.submit()"> 
          <option value="en" >English</option>
          <option value="ru" >Русский</option>
          <option value="tj" >Точики</option> 
          </select> 
    </form>
</td> 

That's it!

Remove all the semicolon you have given in all the option tag end. So your code should be like the below.

<td width="85%" align=right class=top_section> 
          <form action="init.inc.php" method='post'>
          <select name="switchlanguage" id="switchlanguage"> 
          <option value="en" >English</option> 
          <option value="ru" >Русский</option> 
          <option value="tj" >Точики</option> 
          </select> 
    </form>
    </td>
