Question

i want to store the value of a checkbox into my sql database, basically i want to save the default value if it is checked or not.. i am not sure what this would save either true or false?

<div><input type="checkbox" value="Yes" name="chk"/> Yes! I will come!</div>

should I insert into my table like this?

'$_POST[chk]'

Thank you

$_POST[chk] will return the text Yes, in your case, if checked, and won’t set it at all if not. Knowing this, you can set the db field how you want, say 1 or 0 for tinyint type:

$chk = isset($_POST['chk']) ? 1 : 0;
$sql = "update tbl set chk1 = $chk";
