Problem while pushing RFID tag data to server

I am trying to push the RFID tag information to thingspeak server via arduino wifi shield. i am not getting any error but my data is not pushing into server. Can anyone help me to resolve this?

#include <SPI.h>
#include <WiFi.h>
int val = 0;
char code[10];
int bytesread = 0;
char ssid = “UTStarcom-bsnl”; // your network SSID (name) //ITS OpEN
IPAddress server ( 184, 106, 153, 149 );
int status = WL_IDLE_STATUS;
// Initialize the Wifi client library
WiFiClient client;
// server address:
unsigned long lastConnectionTime = 0; // last time you connected to the server, in milliseconds
boolean lastConnected = false; // state of the connection last time through the main loop
const unsigned long postingInterval = 5*1000; // delay between updates, in milliseconds
String writeAPIKey = “6ZBMK0KXQTVS7FJW”; //ur thingspeak api???
void setup() {
//Initialize serial and wait for port to open:
Serial.begin(9600);
// check for the presence of the shield:
if (WiFi.status() == WL_NO_SHIELD) {
Serial.println(“WiFi shield not present”);
// don’t continue:
while(true);
}
String fv = WiFi.firmwareVersion();
if( fv != “1.1.0” )
Serial.println(“Please upgrade the firmware”);

// attempt to connect to Wifi network:
while ( status != WL_CONNECTED) {
Serial.print("Attempting to connect to SSID: ");
Serial.println(ssid);
// Connect to WPA/WPA2 network. Change this line if using open or WEP network:
status = WiFi.begin(ssid);

// wait 10 seconds for connection:
delay(10000);
}
// you’re connected now, so print out the status:
printWifiStatus();
}

void loop() {
int i, k = 0;
// if there’s incoming data from the net connection.
// send it out the serial port. This is for debugging
// purposes only:
if(Serial.available() > 0) { // if data available from reader
if((val = Serial.read()) == 10) { // check for header
bytesread = 0;
while(bytesread<10) { // read 10 digit code
if( Serial.available() > 0) {
val = Serial.read();
if((val == 10)||(val == 13)) { // if header or stop bytes before the 10 digit reading
break; // stop reading
}

}
