Even if you change Post to get then also there is no change in http request query.

The sign-in module is working fine but signup is not working.

Answer 1

Change Method GET to POST

 <?php
$attributes = array(
 'name' => 'sign-up_form',
 'id' => 'sign-up_form',
 'method' => 'POST'
);

And

Foreach your field add name attribute like this..

$data = array(
 'name'=>'name',
 'id' => 'name',
 'type' => 'text',
 'class' => 'input'
);

And

$data = array(
 'name' => 'username'
 'id' => 'username',
 'type' => 'text',
 'class' => 'input'
);

And so on... for sign-up form.

Then you can get your fields based on name using $this->input->post('name');

• Shaleen Jain: Thank you @Hek mat. What is the difference between id and name? Just for my reference.
• Hikmat Sijapati: Form are always posted based on field names.you can use id for javascript validation or defining css.
