Codimentary form validation form ...

Question

I create an input form on a specific post page, for example. (Property / rent / rec_id). Upon presentation, data should be inserted, verified and returned to the original page from which it was sent with any relevant messages.

• If the validation fails, reload the form page to re-fill the form

• Echo a specific validation error. Invalid email address etc.

• If successful, insert the data, reload the page and display a success message.

  function class () {

  $this->load->library('form_validation');    
  $this->form_validation->set_rules('name','name','required|trim');
  $this->form_validation->set_rules('email','email','required|trim|valid_email');
  
  $fields['name'] = 'Name';
  $fields['email'] = 'Email Address';
  
  $this->validation->set_fields($fields);
  
  if ($this->form_validation->run() == FALSE) 
  {
      //failed - reload page and re-populate fields with any error messages
  }
  else
  {
       // display form with success message
  }
  

  }

            'email'=>NULL);
 //setting validation rules
    $this->form_validation->set_rules('name', 'Name', 'required');
    $this->form_validation->set_rules('email', 'Email', 'required|email');

//here you will get all data which user entered in form 
$insertData = $this->input->post(NULL, TRUE);

if ($this->form_validation->run() == FALSE) 
{
    //failed - reload page and re-populate fields with any error messages
    $this->load->view('view_name',$insertData)    

}
else
{
     //set flash data for displaying success message in redirected page
     $this->session->set_flashdata('success','Success message')
     redirect('controller_name');

}

<?php if ($this->session->flashdata('succes_message')) { echo    $this->session->flashdata('succes_message'); ?> } ?>

To alleviate the problem, you can simply do client-side validation using Javascript / jQuery. So basically, instead of going directly to a new page, the “Submit” action will simply be redirected to your javascript function, which will decide if the form is valid. Then you can use jQuery to make everything look beautiful for invalid elements.
