Php form isset with multiple brackets

Question

I have a check box with a name of:

<input type='checkbox' name ='schedule[".$row['id']."][1]' />

I want to check if the check box was checked with the PHP isset(...) And I tried it as

isset($_POST['schedule[".$row['id']."][1]]);

But this didn't work. Any ideas that how It can works?

Answer 1

Try it like:

isset($_POST['schedule'][$row['id']][1])

Simply treat it as multi-D array in this case and edit particular index of schedule key.

Answer 2

After the submission of form the GLOBAL VARIABLES $_POST passes the data as string or int instead of original variables.

To check if checkbox was checked try this one:

$id = $row['id'];
if(isset($_POST['schedule'][$id][1])) {
     echo "hello world";
}
