I thing you are using POST method in your search form. Try with get method. — Prakash Saini, Nov 26 '16 at 10:25
how to use input get? I'm trying to use it like this `$keyWordRestoran_ip = $this->input->get('input-keyword'); ` nothing happen @PrakashSaini — Nicky Apriliani, Nov 26 '16 at 10:33
Please only include the _relevant_ code in your question. In this case, the search form, any JS that might connected to your search form and the resulting code that handles the actual search. — M. Eriksson, Nov 26 '16 at 10:36
You seem to have a form in a form. What does this: `echo form_open('home_controller/search_bar');` output? That's where you need to use `method="GET"`. — M. Eriksson, Nov 26 '16 at 10:46

You have included form two times. One form is created using <?php echo form_open('home_controller/search_bar');?> and another is static in html.So need to remove static html form and for_open is ok. In form_open you need to specified the method get. Here i have updated this code-

<div class="header-bottom">
    <div class="col-xs-1">
        <button class="toggle-button"></button>
    </div>
    <div class="col-xs-11">
    <?php echo form_open('home_controller/search_bar',array('method' => 'get'));?>
    <div class="search">

        <input type="text" id= "input-keyword" name="input-keyword" placeholder="Search ..." value="<?php echo set_value('input-keyword')?>" >
        <input type="submit" value="">  
    </div>
   <?php echo form_close(); ?> 
    </div>
<div class="clearfix"> </div>

At you controller in search_bar function now get form value using get method instead of post like as

$keyWordRestoran_ip = $this->input->get('input-keyword');
