mySQL->updating/inserting "compound" records - php

Question

I have 2 tables structured like this:
CREATE TABLE `exp_ws_gk_text` (
`WGT_RID` INT(9) NOT NULL AUTO_INCREMENT,
`WGT_PRG_CODE` VARCHAR(5) NOT NULL,
`WGT_TEXT` VARCHAR(4000) NOT NULL,
INDEX `PrimaryKey` (`WGT_RID`)
)
CREATE TABLE `exp_ws_gk_state` (
`WGS_RID` INT(9) NOT NULL AUTO_INCREMENT,
`WGS_TYPE` INT(9) NOT NULL,
`WGS_STATE` VARCHAR(3) NOT NULL,
`WGS_WGT_RID` INT(9) NOT NULL,
INDEX `PrimaryKey` (`WGS_RID`),
INDEX `SecondaryKey` (`WGS_TYPE`, `WGS_STATE`)
)
This is how I query the data to be used in a site:
SELECT a.wgt_rid id, a.wgt_text text, a.wgt_prg_code prg_code,
b.wgs_state state, b.wgs_type type,
FROM exp_ws_gk_text a, exp_ws_gk_state b
WHERE a.wgt_rid = b.wgs_wgt_rid
I present the record with all the data returned. Now, when I want to edit or append a record, how would I save the data correctly if the data got sent from a form with these parameters:
$id = intval($_REQUEST['id']);
$prg_code = $_REQUEST['prg_code'];
$state = $_REQUEST['state'];
$crs_type = $_REQUEST['type'];
$text = $_REQUEST['text'];
An insert:
$sql = "BEGIN; ".
" INSERT INTO exp_ws_gk_text (WGT_PRG_CODE, WGT_TEXT) ".
" VALUES('".$prg_code."', '".$text."'); " .
" INSERT INTO exp_ws_gk_state (WGS_STATE, WGS_TYPE, WGS_WGT_RID) ".
" VALUES('".$state."', ".$course_type.", LAST_INSERT_ID()); ".
"COMMIT;";
$mysql_query($sql);
$sql = "SELECT WGS_WGT_RID id FROM exp_ws_gk_text WHERE WGS_RID = ".mysql_insert_id();
$result = mysql_query($sql);
$r = mysql_fetch_array($result, MYSQL_ASSOC);
echo json_encode(array(
'id' => $r["id"],
'prg_code' => $prg_code,
'state' => $state,
'type' => $type,
'text' => $text
));
A delete:
DELETE a, b FROM exp_ws_gk_text a
JOIN exp_ws_gk_state b ON a.WGT_RID = b.wgs_wgt_rid
WHERE a.WGT_RID = :id

Answer 1

$sql = "UPDATE exp_ws_gk_text a, exp_ws_gk_state b
SET a.WGT_PRG_CODE = ".$prg_code.", a.WGT_TEXT = ".$text.", b.WGS_STATE = ".$state.", b.WGS_TYPE = ".$crs_type."
WHERE
a.WGT_RID = ".$id." AND a.WGT_RID = b.wgs_wgt_rid";
