Altering $this->data through $this->assign() doesn't work for common_gpc

[GoogleCodeExporter]

Steps to reproduce the problem:
   #1 declare a common_gpc name x
   #2 use $this->assign('x',$new_value) on pre_mode_process()
   #3 access $this->data['x'] on process_mode_y()

expected output:
altered $this->data['x']

actual output:
original gpc value, not the assign() on step #2

One of the work arounds for now is to use a different name for it

I think this is important

solution 1.0:

we have to pass an updated $common_gpc to process_mode and post_mode_process

question: how to pass the updated var?
possible solution: pass $this->data instead

^ ALL WRONG

the problem is here 

         $merged_gpc = array_merge($reserved_gpc, $common_gpc, $mode_gpc);

         $this->assign($merged_gpc);
         $this->assign('mode',$mode);
         $this->assign('sub_mode',$this->sub_mode);

$this->assign($merged_gpc) overwrites the update variables

Weird: On this code, it appears as if that $this->data doesn't exist yet

Original comment by albertdi...@gmail.com on 3 Mar 2014 at 5:25

[GoogleCodeExporter]

Well it probably doesn't exist yet

   /**
    * Process before the main mode process
    *
    * @param array $common_gpc
    * @since ADD MVC 0.9
    */
   public function pre_mode_process($common_gpc) {
   }

Possible fix:

         $merged_gpc = array_merge($this->data,$reserved_gpc, $common_gpc, $mode_gpc);

         $this->assign($merged_gpc);
         $this->assign('mode',$mode);
         $this->assign('sub_mode',$this->sub_mode);

I think I need a testing file first

Original comment by albertdi...@gmail.com on 3 Mar 2014 at 5:38

[GoogleCodeExporter]

This:

         $merged_gpc = array_merge($reserved_gpc, $common_gpc, $mode_gpc,$this->data);

test file:

<?php

require 'add_configure.php';

CLASS ctrl_issue_129 EXTENDS ctrl_tpl_page {
   public $common_gpc = array(
         '_GET' => array( 'x' )
      );

   public $mode_gpc_test = array();

   public function pre_mode_process($common_gpc) {
      debug::var_dump($common_gpc);
      $this->assign('x',$common_gpc['x']+1);
      debug::var_dump($this->data);
   }

   public function process_mode_test($gpc) {
      debug::var_dump($gpc,$this->data['x']);
   }
}

$ctrl = new ctrl_issue_129();
$ctrl->execute();
