                echo "<meta http-equiv='refresh' content='1'>";
            }
            else
            {
                $this->session->set_flashdata('message', '<p style="color: red;font-weight: bold;">Error!</p>');
            }
        }
        $this->load->view('product-master');
    }
}

view: product-master.php

<?php echo $this->session->flashdata('message');?>
<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

you need to add action to form tag. <form role="form" method="post" action="<?php echo site_url('purchase/add_product_master');?>"> — スージン

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;

B. Desai Over a year ago

submit button are work when action method is applied is wrong statement. If request to be sent on same url/page then action is not required.

@B.Desai thanks for correction. try changing if($this->input->post('submit')) to if (!empty($_POST))

the action attribute is missing in your form, So you should add action attribute while adding form to your document.

<form class="form-horizontal form-label-left" method="post" action="URL">
