CodeIgniter - File upload required validation

CodeIgniter - File upload required validation

Que:

<?php echo form_open_multipart('add'); ?>

<fieldset>

    <input type="text" name="name" /><br>

    <input type="text" name="code" /><br>

    <input type="file" name="userfile" /><br><br>

    <input type="submit"value="Add" />

</fieldset>

<?php echo form_close(); ?>

Ans:

I found a solution that works exactly how I want.

I changed

$this->form_validation->set_rules('name', 'Name', 'trim|required');

$this->form_validation->set_rules('code', 'Code', 'trim|required');

$this->form_validation->set_rules('userfile', 'Document', 'required');

To

$this->form_validation->set_rules('name', 'Name', 'trim|required');

$this->form_validation->set_rules('code', 'Code', 'trim|required');

if (empty($_FILES['userfile']['name']))

{

    $this->form_validation->set_rules('userfile', 'Document', 'required');
}
