Arduino uno + Ethernet shield + rc522 and mysql database

Hello, I'm having a real head ache because of a MFR522 chip reader, first of all i want to mention it was working before in a different domain, basically all i want is to scan the id info stored in some chips to print a registry in this domain 1condotbtc/demo and have access to a users profile that i created before (linking the registry database with other containing profiles url's), i have linked an ftp user with a database and its proper user in my personal domain (and hostingspace). this part seem to be working i have tested and everything is fine

but when i try to read the chip and store the information in the sql database nothing shows up, that means nothing is reaching the database, i think the reader is not working because it should be printing "OK" in the serial monitor when the information is uploaded, but i can't be really sure if that is the problem because i recently change mfrc522 library i'm actually using 2(MFRC522-1.3.6.zip) and IDE1.6.13 and i'm a little bit confused with it, i don't how can i test the reader without dismounting everything? any suggestions for my code? am i calling the reader wrong? Help me please!!

Why? The pin is an INPUT pin, so you just turned the internal pullup resistor on. But, then you make it an output pin. You REALLY need some comments to explain that.

The example you started from is the poorest example on the internet. That code causes loop() to do absolutely nothing unless there is a valid card presented. That POS should have been written to take action when there is a card presented, not do nothing until a card is presented.

You asked the server to do something. It tried to tell you something. You told it to f**k off, that you didn't want to hear what it had to say. And, yet nothing is written into the database, and you don't know why.

Perhaps if you hadn't told the server what to do, it might have told you what the problem was.

A link to the hardware you are using, and referring to by more than one name, would help us determine if there is possibly a pin or SPI conflict.
