mwhitney also mentioned that there is some problem with <form> please check the following and suggest.

PHP Code:
<!DOCTYPE html> <html lang = "en"> <head> <meta charset = "utf-8"> <title>Students Example edit</title> </head> <body> <form method = "" action = ""> <?php echo form_open('Stud_controller/update_student'); echo form_hidden('old_roll_no',$old_roll_no); echo form_label('Roll No.'); echo form_input(array('id'=>'roll_no','name'=>'roll_no','value'=>$records[0]->roll_no)); echo "<br/>"; echo form_label('Name'); echo form_input(array('id'=>'name','name'=>'name','value'=>$records[0]->name)); echo "<br/>"; echo form_submit(array('id'=>'submit','value'=>'Edit')); echo form_close(); echo $this->db->last_query(); ?> </form> </body> </html>

There should be no quotes its an integer

@nadeem14375: What's you question? Your post only contains quotes from earlier posts, right?

(07-30-2016, 11:08 PM)thanks Wouter60, I am new so, these are stupid questions. can you guide me to some templates that I can easily implement to build forms? Wrote: @nadeem14375: What's you question? Your post only contains quotes from earlier posts, right?

There are probably more roads to the same solution, but I'll try to describe the approach that is most common in CI.
This is a very basic example, using model, view and controller.

Controller: Stud_controller

PHP Code:
public function update_student($id)
{
   $this->load->model('stud_model');
   if ( ! $this->input->post('submit') ) {
        // if the form is not yet submitted, then show the form
        $data['record'] = $this->stud_model->get_student($id);
        $this->load->view('student_form',$data);
   }
   else {
        // form is submitted; update the record in the database
        $data = array(
            'name' => $this->input->post('name'),
            'roll_no' => $this->input->post('roll_no')
        );
        $this->stud_model->update_student($id,$data);
        redirect('/');  //return to your home page
   }
} 

Model: stud_model

PHP Code:
public function get_student($id)
{
//fetch a record from the table 'students', for the given id
$query = $this->db->get_where('students', 'id=' . $id, 1);
if ($query->num_rows() > 0) {
   return $this->query->row_array();
}
else {
   return FALSE;
}
}

public function update_student($id,$data)
{
//update the record in the table 'students'
$this->db->update('students', $data, 'id=' . $id);
} 

View student_form

PHP Code:
<?php 
if (! $record) {
    show_error('There is no student with this id in the database');
    die();
}
echo form_open();  //the form will be submitted to the same url as it was called from
echo 'Name: ' . form_input('name',$record['name']) . '<br />';
echo 'Roll_no: ' . form_input('roll_no', $record['roll_no']) . '<br />';
echo form_submit('submit','Submit form');  //important: the submit button should have a name, in this case: 'submit'
echo form_close();
?>
