Hi,

I have a script to save Google Map markers in SQL.
The datas from "type" and "type2" should be compared to datas in existing table "type_table"

Unfortunatly the script does not save the datas. I always get the echo from "if($num_rows==0)", even if the gives datas from the formular match to "type" and "type2" in "type_table".

Can some please take a look to the script? I do not find the mistake... :(

Thanks a mill!

Moerkel,

It may not be the only thing but ....

Client-side: xmlHttp.open('POST', 'phpsqlinfo_addrow.php', true); ...
Server-side: $colour = $_GET['colour']; etc.
are incompatible.

Try: $colour = $_POST['colour']; etc.
