$idx not incrementing?

#1
Hi guys,

I have two buttons on the form 'yes' or 'no' button.

now when these button are clicked it will call the show_qa() methods below,



Code:
   public function show_qa()
   {
       $content = $this->session->userdata('content_data');
       #showArray($content);    
       
       //Get language, version and topic
       $language = $content['subject'];
       $version = $content['version'];
       $topic = $this->uri->segment(3, 0);
       $array_init = $this->uri->segment(4, 0);
       
       //Begin initializing array...
       //do this once only.
       if($array_init == 'init') {
           $this->set_array_container($language, $version, $topic);       //do only once
           reset($this->array_container); //set the array pointer in the very first index which is zero.
           $idx = key($this->array_container);  
           $this->save_idx_position($idx);    
       }
       
       //Begin catch yes or no button
       if (isset($_POST['yes']) || isset($_POST['no'])) {
               #$this->array_container = $this->fetch_array_from_session();
           
               $last_idx = $this->get_last_idx_key();
               $idx = $this->get_idx_position();
               
               if($idx < $last_idx) {
                   $idx++;
               }
               
               $this->save_idx_position($idx);    
               
               $idx = $this->get_idx_position();
           }
       //End catch yes or no button

       showArray($this->array_container);
       echo '<b>Index position: '. $idx . '</b></br></br>';              
       
       //replace blank space with underscore
       $topic_underscore = str_ireplace(" ", "_", $topic);
       $this->session->set_userdata('topic', $topic_underscore);    

       #get current url and store to session
       $segments = array('language', 'show_qa', $topic_underscore);
       $qa_url = site_url($segments);        
       $this->session->set_userdata('qa_url', $qa_url);    
       
       $this->qa_ids = $this->qa_mdl->get_qa_ids($language, $version, $topic);
       
       #echo '<br>value: '. $current_idx->qa_id;
       
       $this->dryview2($header='templates/header', $msg='Welcome back ', $menu='templates/menu', $content='templates/landing_qa', $footer='templates/footer', $master='templates/landing_master');
   }

when you click either 'yes' or 'no' for the first time it increments the $idx from 0 to 1.
and when you click again those 'yes' or 'no' buttons the 2nd, 3rd, 4th etc... times...
It will not increments anymore.

Any suggestions, please?

Thanks in advance.

Okay no worries guys,
I already solved this.

here is the modified codes,

if($array_init === 'init') {
$this->set_array_container($language, $version, $topic); //do only once
reset($this->array_container); //set the array pointer in the very first index which is zero.
$idx = key($this->array_container);
$this->save_idx_position($idx);
echo '<br>Array_init: '. $array_init;
}
