Multipart enctype and checkbox arrays

[travisbrown]

I have a form I need to submit as a multipart enctype. Problem is, I'd usually retrieve all the values from a checkbox group as a comma-delimited array. When i use multipart, I only get the first value (using Upload.Form with Persists ASP Upload)

Request.form(“ingredient_id”)
ingredient_id = 2,3,5,8,7,33

With ASPUpload, after changing the enctype, I only get the first value

Upload.Form("ingredient_id")
ingredient_id = 2

Is there a way to collate the values so i can process them with a loop?

The BinaryRead on the post looks like this

7d7d0301065e Content-Disposition: form-data; name="ingredient_id" 1 -----------------------------7d7d0301065e Content-Disposition: form-data; name="ingredient_id" 3 -----------------------------7d7d0301065e Content-Disposition: form-data; name="ingredient_id" 4 -----------------------------7d7d0301065e Content-Disposition: form-data; name="ingredient_id" 8 -----------------------------7d7d0301065e Content-Disposition: form-data; name="ingredient_id" 5 -----------------------------7d7d0301065e Content-Disposition: form-data; name="ingredient_id" 6 -----------------------------7d7d0301065e Content-Disposition: form-data; name="ingredient_id" 7 -----------------------------7d7d0301065e Content-Disposition: form-data; name="ingredient_id" 9 -----------------------------7d7d0301065e Content-Disposition: form-data; name="ingredient_id" 36 -----------------------------7d7d0301065e Content-Disposition: form-data; name="ingredient_id" 85 -----------------------------7d7d0301065e Content-Disposition: form-data; name="ingredient_id" 105 -----------------------------7d7d0301065e Content-Disposition: form-data; name="ingredient_id" 126 -----------------------------7d7d0301065e--

In the meantime, and maybe this is the best way to do it anyways, I created a string with javascript. I'd rather do this serverside, but...

<script type="text/javascript">
function CollateIngredients() {
	var cbCollection = document.forms[0].elements['ingredient_id'];
	var checkboxarray
	var counter = 0
	for ( var i = 0; i < cbCollection.length; i++ ) {
		if ( cbCollection[i].checked )  {
			if ( counter == 0 ) 
				{checkboxarray = cbCollection[i].value;}
			else 
				{checkboxarray = checkboxarray + ',' + cbCollection[i].value;}
				counter = counter + 1;
		}
	}
	
	document.getElementById('product_ingredients').value = checkboxarray;
	alert(document.getElementById('product_ingredients').value);
}
</script>
