I WANT TO USE Multi CHECKBOXS TO CARRY OUT A SEARCH QUERY.

MY fORM USES $HTTP_GET_VARS

They way i think it sould work is as follows ?

I NEED TO MAKE THE CHECKBOXES IN TO ARRAYS on the page with the search ie.

input name="sizeID[]" type="checkbox" id="sizeID[]" value="1"
input name="sizeID[]" type="checkbox" id="sizeID[]" value="2"
input name="sizeID[]" type="checkbox" id="sizeID[]" value="3"

On the results page I need to modify (isset)the standard DW code at the line below - and use implode so i can convert the Array into a string.



if (isset($HTTP_GET_VARS["sizeID"])) {
colname_RSbrand = (get_magic_quotes_gpc()) ? $HTTP_GET_VARS["sizeID"] : addslashes($HTTP_GET_VARS["sizeID"]);
}

I am tearing my hair out (whats Left of it ) trying to get the syntax to work. I have searched the talkzone but found nothing to assist.

this is what is change so far also the error i get.

if (isset($HTTP_GET_VARS["sizeID"])) {
$size = implode(',',$HTTP_GET_VARS['sizeID']);
// colname_RSbrand = (get_magic_quotes_gpc()) ? $HTTP_GET_VARS["sizeID"] : addslashes($HTTP_GET_VARS["sizeID"]);
$colname_rscat = $size;
}


i get error "You have an error in your SQL syntax near '4 AND sizeID = Array at line 1"
