checkboxes in array check isset

[UnknownPlayer]

I have this code:

			$query = "SELECT * FROM boje";
		$result = mysql_query($query, $connection);
		while ($boja = mysql_fetch_array($result)) {
			echo '<input type="checkbox" name="boja[]" value="'.$boja['id'].'" />'
		}

Now problem is when i click submit, and when go through this code:

			foreach ($_POST['boja'] as $boja_id) {
			if (isset($boja_id)) {
				echo "isset";
			} else {
				echo "not isset";
			}
		}

 

this works for checkboxes which are checked, but it doesn't show echo message for checkboxes which are not checked(not isset, else code..), what is the problem, and how can i make solution for this?

Thanks..

the check-boxes will only post a value if they're selected, so the $_POST['boja'] array will only contain the values of the checked boxes

And there is no way that he can contain values 0 and 1, i mean in this example ?

I can't see why you would want to do that. Maybe explain what you're trying to accomplish and I can help better.

Instead of using the foreach to test which checkboxes were checked, what about using the while loop used to create the checkboxes again? You could loop through the database values to see which ones appear in the passed array.

 

Note that I'm not very familiar with using the array syntax for checkboxes, so I'm not sure what the code would be off hand.

Something like this should do the trick

 

$query = "SELECT * FROM boje";
$result = mysql_query($query, $connection);

$boja_checked = $_POST['boja'];

while ($boja = mysql_fetch_array($result))
{
$checked = (in_array($boja['id'], $boja_checked)) ? 'checked="checked"' : '';
echo '<input type="checkbox" name="boja[]" value="'.$boja['id'].'" ' . $checked . ' />';
}
