Re: checkbox arrays and validation

but what I want to clarify is that if I change my PHP echo statement to: echo("<input type=checkbox name=chkmodels value=" . $row['models_id'] . ">" . $row['models_type'] . "<br>"); basically without the [] then it is still recognised as an array. But when the array is passed back it is returned as a string separated by commas. Then I should use the split() function to create an array.

If you leave off the [], then only the last checkbox value remains in $_POST['chkmodels']. It is not passed as a comma separated string. If you look at the query string, you'll see something like this: ?chkmodels=1&chkmodels=2 which means PHP makes $_POST['chkmodels'] equal to 1 for the first variable, then sets the same $_POST['chkmodels'] equal to 2 for the second variable in the query string. End result is one value (not an array) remaining in $_POST['chkmodels']. -- ---John Holmes...
