Try like below with form validation
https://www.codeigniter.com/user_guide/libraries/form_validation.html
https://www.codeigniter.com/user_guide/libraries/form_validation.html#rule-reference
EXAMPLE
public function update_profile() {
$this->load->library('form_validation');
// You can change what you want set for the rules your self this just example:
$this->form_validation->set_rules('pass', 'pass', 'trim|required');
$this->form_validation->set_rules('con_pass', 'con_pass', 'trim|required|matches[pass]');
$this->form_validation->set_rules('phone_no', 'phone_no', 'trim|required');
if ($this->form_validation->run() == TRUE) {
// Update model stuff
}
$email = $_SESSION['email']; // User id instead of email.
$profile_data = $this->users_model->getprofile($email);
if ($this->input->post('pass')) {
$data['pass'] = $this->input->post('pass');
} elseif (!empty($profile_data)) {
$data['pass'] = $profile_data['pass'];
} else {
$data['pass'] = '';
}
if ($this->input->post('con_pass')) {
$data['con_pass'] = $this->input->post('con_pass');
} elseif (!empty($profile_data)) {
$data['con_pass'] = $profile_data['con_pass'];
} else {
$data['con_pass'] = '';
}
if ($this->input->post('phone_no')) {
$data['phone_no'] = $this->input->post('phone_no');
} elseif (!empty($profile_data)) {
$data['phone_no'] = $profile_data['phone_no'];
} else {
$data['phone_no'] = '';
}
$this->load->view('provider/profile', $data);
}
Model function
public function getprofile($email) {
$this->db->where('email', $email);
$query = $this->db->get('users');
return $query->row_array();
}
View Example
<?php echo form_open('profile/update_profile'); ?>
<?php echo validation_errors();?>
<input type="password" name="pass" value="<?php echo set_value('pass', $pass);?>"/>
<input type="password" name="con_pass" value="<?php echo set_value('con_pass', $con_pass);?>"/>
<input type="text" name="phone_no" value="<?php echo set_value('phone_no', $phone_no);?>" />
<?php echo form_submit(array('id' => 'submit', 'value' => 'Update')); ?>
<?php echo form_close();?>
