Codeigniter checking checkbox value

Question

I\'m using CodeIgniter and I have a form with a checkbox that allows the user to check and remove their uploaded photo.
In my controller I use if(isset($checked)

Answer 1

remove isset

its because by default in your CI Controller you get input value using

$checked = $this->input->post('remove');

whether is has a value or not your variable now exist..

Answer 2

Please write proper value in your checkbox :-

   <input id="remove" type="checkbox" name="remove">

Write some value then check it :-

for e.g :

  <input id="remove" type="checkbox" name="remove" value="1">

In php :-

   if($checked == 1) {
      // do whatever u want
   }

Answer 3

Try:

<input id="remove" type="checkbox" name="remove" value="1">

Answer 4

Use this if it can help.

$checked = (isset($_POST['checkbox']))?true:false;

Answer 5

What you need to do here is to change this line ...

if(isset($checked) == 1){

to

if((int) $checked == 1){

The reason is that the variable $checked will always be set whether its value is 1 or not. $checked = $this->input->post('remove'); will return NULL if the 'remove' is not set in the POST data.
