Send value to php file
<p>I'm try to send a value to a PHP file, but when I check, this value became <code>null</code>.</p>

<p>I send the value by: user_login.php?p_action=New_User</p>

<p>The code of user_login.php is:</p>

<pre><code>require("include/session_inc.php");
require("include/user_handling_inc.php");
require("include/db_inc.php");

start_Session(false, false);

switch ($p_action) {
case 'Login': {
 $l_flag = verify_User($p_in_username, $p_in_password);
 if ($l_flag == "Not_Found") {
     $l_flag = "New_User";
 }
 break; 
}
case 'Save_Profile': {
$l_flag = "Save_Profile";
    break;
}
case 'New_User':
$l_flag = "New_User";
    break;
case 'Create_New_User':
$l_flag = "Create_New_User";
}

switch ($l_flag) {
    case 'New_User': {
    include "include/user_new_inc.php";
    break;
  }
case 'Save_Profile': {
    load_User_Data(" username = '$p_in_username' ", false);
    include "include/user_profile_save_inc.php";
    break;
  }
case 'Wrong_Password': 
    echo "Wrong Pass";
    break;
case 'OK': 
    load_User_Data(" username = '$p_in_username' ", true);
    store_User_Cookie($g_userdata-&gt;user_id);
    include "include/user_profile_inc.php";
    break;
case 'Create_New_User':
$l_user_id = create_New_User ($p_in_username, $p_in_email, 'Y');
    if ($l_user_id != -1) {
        store_User_Cookie($l_user_id);
        echo "Success !! &lt;br&gt;&lt;br&gt; \n";
        echo "&lt;a href\"/index.php\"&gt; Back to Main &lt;/a&gt;";
     }
break;
}
</code></pre>
