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!
