Question

I want to pass a language id for each link i click from my view to controller.
My view code is

  <?php foreach ($languages as $lang) { ?>
     <li>
       <a href="<?php echo base_url(); ?>home/box/<?php echo $template_data['box_id']?>/<?php echo $lang['language_name']?>"></a>
     </li>
   <?php } ?> 

My controller is

public function box($box_id=null, $language_name=null, $language_id=null) {
   /// my function code
        echo $box_id;
        echo $language_name;
        echo $language_id;
   $data['languages'] = $this->Home_model->getLanguages($box_id);
  }

The languages array contain the language id and language name

i want the name to be in url but not the id

The url looks like this

http://localhost/mediabox/home/box/12/en

if i send the language id in url it is then visible otherwise it is not visible in the controller.
How can I get language id for each link in controller without sending it in url

Thanks

Answer 1

pass the language name in the url without the ID, compare to languag_name column in table.

Lets assume you have url: http://localhost/mediabox/home/box/en

controller

<?php
# I wont write a controller but you should know how to do that, im also writing code as if you are just focusing on getting language.
public function box( /**pass in your other uri params as needed **/ $lang_name = 'en'){
  #you could load this in the constructor so you dont have to load it each time, or in autoload.php if your using it site wide.
  $this->load->model('lang_model', 'langModel');

  #this example shows loading the library and running the function
  $this->load->library('lang_library');
  $this->lang_library->_getLang($lang);

  #this example shows putting the getLang function inside the controller itsself.
  self::_getLang($lang);
}

library/private function

<?php
private functon _getLang($lang = 'en'){
  #run the query to retrieve the lang based on the lang_name, returns object of lang incl id
  $lang = $this->langModel->getLang($lang_name);
  if (!$lang){
    die('language not found');
  }else{
    return $lang;
  }

lang model

<?php
public function getLang($lang_name = 'en'){
  $this->db->where('lang_name', $lang_name);
  $this->db->limit(1);
  $q = $this->db->get('languages');

  if ($q->mysql_num_rows > 0){
    return $q->result();
  }else{
    return false;
  }
}

you will then have a variable with object associated to it then you can simply call $lang->lang_name; or $lang->lang_id;

Session storage

<?php
#you could call this in the beginning after using an ajax `$.post();` to retrieve the ID.. the easiest route though is whats above. I use this in my REST APIs
$this->session->set_userdata('lang', $lang);
