Server validation for multi insert checkbox

I have a form with a multi-insert checkboxes created using a repeat region and a recordset.

is it possible to add server side validation so that an error occurs if no boxes are checked, but no error if one or more are selected ?

using the wizard, i added server side validation to 2 other form fields, but adding validation to the check boxes doesn't seem so intuitive

when using a checkbox group, the name of the group will end in "[]":
<input type="checkbox" name="CheckboxGroup1[]" value="checkbox" id="CheckboxGroup1_0" />

In server validations, when you select one of the checkboxes to apply the Required validation to, the code in the value box will look like this:

<?php echo((isset($_POST["CheckboxGroup1[]"]))?$_POST["CheckboxGroup1[]"]:"") ?>

you will need to manually remove the "[]" from that code:

<?php echo((isset($_POST["CheckboxGroup1"]))?$_POST["CheckboxGroup1"]:"") ?>

must be doing something wrong.

My checkbox group doesn't end in [].

The attached page works, in so far as it adds rows to the appropriate tables.

The dataassist add multiple record wizard adds the code blocks, (but they need to be moved for the server behavior to work properly), but with this done i can't do any more

When i try and add server side validation to the categoriescheck boxes , the categories check box isn't seen by the wizard,

i added it manually (line 30), but now nothing is posted. so I commented out the validation

this is not the same as a checkbox group.


Server validations cannot be used to validate checkboxes used in a multiple insert behavior like this.


the problem is that the checkboxes are dynamically named.


to work around this, add the following hidden form element just before the submit button:

<input name="checkCount" type="hidden" id="checkCount" value="<?php echo $RepeatSelectionCounter_1; ?>" />

and add this code at line 1:

<?php

if ($_SERVER["REQUEST_METHOD"] == "POST") {

    $checked=0;

    $iterations = isset($_POST['checkCount'])?$_POST['checkCount']:0;

    for($i=0; $i<=$_POST['checkCount'];$i++) {

        if(isset($_POST['CheckboxGroup1_'.$i]) && $_POST['CheckboxGroup1_'.$i] != "") $checked++;

    }

    

}

?>

then use numeric validation. set the server variable to:
$checked


set the minimum number to 1 and the maximum to 10000

Thanks for the clarification - and the solution.
