When i load my controller i'm getting this error in my homepage, but after performing search the error will disappear and search results will be displayed there.

This is my view page:

       <div id="toggle_tst">

       <div class="scroll">

       <?php

    // List up all results.



       echo "<table id='table'>";

       echo "<tbody>";

       echo "<thead>";

       echo "<tr><th>NAME</th><th>Pernor No</th><th>DESIGNATION ID</th> 

       </tr>";

       echo "</thead>"; 

       foreach ($results as $row)

         {

        echo "<tr><td>";

        echo $row['name'];

        echo "</td><td>";

        echo $row['pernor_no'];

        echo "</td><td>";

        echo $row['designation_id'];

        echo "</td></tr>";

           }

        if (isset($_POST['data_rows'])) 

           {

        //if the page has been submitted, append the rows

        echo $_POST['data_rows'];

           }

        echo "</tbody>";   

        echo "</table>";

          ?>

       </div>

       </div>

Controller:

       public function execute_search()

         {

    // Retrieve the posted search term.

        $search_term = $this->input->post('search');

        $data['query'] = $this->JcMeetingExpense_model->viewother();   

        $data['query1'] = $this->JcMeetingExpense_model->viewcatprice();   



         // Use a model to retrieve the results.

        $data['results'] = $this->JcMeetingExpense_model- 

        >get_results($search_term);

         // Pass the results to the view.

        $this->load->view('JcMeetingExpense/jc_meeting_expense',$data);

        }

use isset before going to execute loop.

isset is the best practice if you are using in your code for variables and array.

For your solution : use below code

if(isset($results)){ 

// all code inside it...

}

always use isset() for kind of same condition.

use below code

if(isset($results)){ 

 // all code inside it...



 }

The reason is you haven't set the variable results. So simple solution is to add a isset() before foreach loop.

if(isset($results)){

   foreach ($results as $row){

     .

     .

     .

     .

   }

}
