How to enable disable dropdown based on user logged in? - php

Question

i want to disable my dropdown based on the user login.
I store the user type in session.
Now admin creates user. and then that user can login and edit his details.
I want to allow only some fields to be allowed to be edited by that user.
Like i don't want to allow him to edit his user_type.
Now if i remove them from my form field there comes an error on data truncated in mysql. and if i disable it through html it shows same error.
Please help me
the is controller code:
public function edit ($id = NULL)
{
$user_type = $this->session->userdata('user_type');
if($user_type =="admin")
{
if ($id)
{
$this->data['user'] = $this->user_m->get($id);
count($this->data['user']) || $this->data['errors'][] = 'User could not be found';
// Set up the form
$rules = $this->user_m->rules_admin;
$id || $rules['password']['rules'] .= '|required';
$this->form_validation->set_rules($rules);
// Process the form
if ($this->form_validation->run() == TRUE)
{
$data = $this->user_m->array_from_post(array('emp_id','name','last_name','email','password','phone','gender','designation','user_type','blood_group','date_birth','status','address'));
if(!empty($data['password']))
{
$data['password'] = $this->user_m->hash($data['password']);
} else {
// We don't save an empty password
unset($data['password']);
}
$key=$this->user_m->save($data, $id);
redirect('admin/user/index');
}
}
// Load the view
$this->data['subview'] = 'admin/users/edit';
$this->load->view('admin/_layout_main', $this->data);
}
elseif($user_type=="employee")
{
if ($id)
{
$this->data['user'] = $this->user_m->get_emp($id);
count($this->data['user']) || $this->data['errors'][] = 'User could not be found';
$rules = $this->user_m->rules_admin;
$id || $rules['password']['rules'] .= '|required';
$this->form_validation->set_rules($rules);
// Process the form
if ($this->form_validation->run() == TRUE)
{
$data = $this->user_m->array_from_post(array('emp_id','name','last_name','email','password','phone','gender','designation','user_type','blood_group','date_birth','status','address'));
//$data['password'] = $this->user_m->hash($data['password']);
if(!empty($data['password']))
{
$data['password'] = $this->user_m->hash($data['password']);
} else {
// We don't save an empty password
unset($data['password']);
}
$id = $this->session->userdata('id');
$this->user_m->save($data, $id);
redirect('admin/user/index');
}
}
// Load the view
$this->data['subview'] = 'employee/profile/edit';
$this->load->view('employee/_layout_main', $this->data);
}
else
{
echo "You Seem To Be Lost";
}
}

Answer 1

You can apply check for logged in user type.
If (admin) {
// SHOW DROP DOWN
}
else {
// SHOW JUST TEXT (SELECTED ONE FROM DROP DOWN)
// HIDE THE DROP DOWN BOX USING CSS PROPERTY: `display:none`
}

Answer 2

If ($user_type =="admin") {
$select = '';
}
elseif($user_type=="employee"){
$select = 'disabled';
}
// to prevent warning use this<?php isset($select) ? $select : ''; ?>
// Above is shortcode for if(isset($select)){echo $select;}else{echo '';}
<select <?php isset($select) ? $select : ''; ?> >
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="mercedes">Mercedes</option>
<option value="audi">Audi</option>
</select>
