How can I get Multiple Insert, Update, Delete with MRT all working together??

Delete from relationship table where [ID] = SubCatID  

Thanks so much Jaffa,

I have tried doing this, but to be honest, I'm not grasping it within the code. The second multiple delete behavior is pasted below. I assume that I need to hand code the WHERE clause towards the bottom. But everything I try, fails.

A side note, my repeat selection uses a recordset that references only the Sub Categories table. Is there anything I need to add to the repeat selection to loop through the relational table? Or should I be using a JOIN recordset including both the SubCategory and relational table together for this repeat region/selection?


// WA DataAssist Multiple Deletes
if (isset($_POST["UpdateSubCatBtn_x"])) // Trigger
  if (!
session_id()) session_start();
$WA_loopedIDField = array("WADA_RepeatID_TableID");
$WA_loopedField = array("DelSubCatchecked");
$WA_connection $dbStore;
$WA_table "relCat_SubCat";
$WA_redirectURL "products_Categories.php";
$WA_keepQueryString false;
$WA_indexField "TableID";
$WA_columnTypesStr "none,none,NULL";
$WA_fieldNames explode("|"$WA_indexField);
$WA_columns explode("|"$WA_columnTypesStr);
$WA_comparisions = array("=");
$WA_connectionDB $database_dbStore;
$WA_multipleDeleteCounter 0;
  while (
WA_AB_checkLoopedFieldsNotBlank($WA_loopedIDField$WA_multipleDeleteCounter)) {
    if (
WA_AB_getLoopedFieldValue($WA_loopedIDField[0], $WA_multipleDeleteCounter) == WA_AB_getLoopedFieldValue($WA_loopedField[0], $WA_multipleDeleteCounter)) {
$WA_fieldValuesStr WA_AB_getLoopedFieldValue($WA_loopedIDField[0], $WA_multipleDeleteCounter);
$WA_fieldValues = array($WA_fieldValuesStr);
$deleteParamsObj WA_AB_generateWhereClause($WA_fieldNames$WA_columns$WA_fieldValues$WA_comparisions);
$WA_Sql "DELETE FROM `" $WA_table "` WHERE " $deleteParamsObj->sqlWhereClause;
$MM_editCmd mysql_query($WA_Sql$WA_connection) or die(mysql_error());
  if (
$WA_redirectURL != "")  {
    if (
$WA_keepQueryString && $WA_redirectURL != "" && isset($_SERVER["QUERY_STRING"]) && $_SERVER["QUERY_STRING"] !== "" && sizeof($_POST) > 0) {
$WA_redirectURL .= ((strpos($WA_redirectURL'?') === false)?"?":"&").$_SERVER["QUERY_STRING"];
header("Location: ".$WA_redirectURL);

Lastly, on this delete behavior, do I use the TableID or the Parent_SubCategoryID for the index field? $WA_indexField = "TableID";
In this table, as you can see, the TableID is the unique column.

Thanks again,
