<form class="form-horizontal form-label-left" method="post">
  <input type="text" name="product_name" id="product_name" required="required" />
  <input type="text" name="category" id="category" required="required" />
  <input type="text" name="sub_category" id="sub_category" required="required" />
  <textarea name="description" id="description" required="required"></textarea>
  <input type="submit" name="submit" id="submit" class="btn btn-success" value="submit">
</form>

I have created a form having name product-master.php. But when I click on submit button it does't inserting form value or does't showing any flashdata message don't know why. So, How can I fix this problem ? Please help me.

Thank You

Problem in this line. you need to add action when form is submit

 <form class="form-horizontal form-label-left" method="post"
 action="<?php echo site_url('purchase/add_product_master');?>">

use this code in this function add_product_master at the start of this function

echo "<pre>";
print_r($this->input->post());
exit;
