Multiple data via LoadVars

mySQL databse contains only 2 columns (Availability and Code). I need to send about 50 data at a time to a php file to be sent to mySQL. Basically 50 rows should be added into the mySQL database.

I have no idea how should this be done? Is this agood approach? Is there a better way of getting this done?

///

for (i=0; i<50; i++) {

SenderLoad["dataA"+i] = _root["availability"+i].text;

SenderLoad["dataB"+i] = _root["itemCode"+i].text;

SenderLoad.sendAndLoad("http://www.web.com/the.php",ReceiveLoad,"POST");

}
