Have tested the commands on pc with the module?

yes ,i tested it but it add empty line in data base. i don't knew haw i will add my childs values to the data base.
here the code i used
#include <SoftwareSerial.h>
SoftwareSerial gprsSerial(7, 8);
char a =50;
char b= 10;
void setup()
{
gprsSerial.begin(19200);
Serial.begin(19200);

Serial.println("Config SIM900...");
delay(2000);
Serial.println("Done!...");
gprsSerial.flush();
Serial.flush();

// attach or detach from GPRS service
gprsSerial.println("AT+CGATT?");
delay(100);
toSerial();


// bearer settings
gprsSerial.println("AT+SAPBR=3,1,"CONTYPE","GPRS"");
delay(2000);
toSerial();

// bearer settings
gprsSerial.println("AT+SAPBR=3,1,"APN","internet.ooredoo.tn"");
delay(2000);
toSerial();

// bearer settings
gprsSerial.println("AT+SAPBR=1,1");
delay(2000);
toSerial();
}


void loop()
{
// initialize http service
gprsSerial.println("AT+HTTPINIT");
delay(2000);
toSerial();

// set http param value
gprsSerial.print("AT+");
gprsSerial.print("HTTPPARA="URL",");
gprsSerial.print(""http://psia.eduinfo.tn/requete.php");
gprsSerial.print("?humidite=");
gprsSerial.print(a);
gprsSerial.print("&reponse=");
gprsSerial.print(b);
gprsSerial.println(""");


delay(2000);
toSerial();

// set http action type 0 = GET, 1 = POST, 2 = HEAD
gprsSerial.println("AT+HTTPACTION=1");
delay(6000);
toSerial();

// read server response
gprsSerial.println("AT+HTTPREAD");
delay(1000);
toSerial();

gprsSerial.println("");
gprsSerial.println("AT+HTTPTERM");
toSerial();
delay(300);

gprsSerial.println("");
delay(10000);
}

void toSerial()
{
while(gprsSerial.available()!=0)
{
Serial.write(gprsSerial.read());
}
}

Is Your test done with pc? Using hyperterminal program. Test your command through this mean. Also make simple test like sms or network base command.
