Web Client- Multiple Push Buttons

Hey Guys,
Im using the standard web client example sketch to do a get request from a local IP.
Im wanting to set up multiple get requests to work from multiple push buttons on input 2, 3, 4 for example. I can get the 1 button to do a get request but can’t work out how to define different digital inputs to do different get requests.

Any help/example codes?

Here is what im currently using for the 1 button and 1 get request

#include <SPI.h>
#include <Ethernet.h>
// this must be unique

byte mac[] = {
0xDE, 0xAD, 0xB8, 0xEF, 0xFE, 0xED };

int systemState = 0;
// change to your network settings

IPAddress ip(192,168,1,113);

// change to your server

IPAddress server(192,168,1,42);

char serverName[] = "192,168,1,42";


int serverPort = 14999;

EthernetClient client;
int totalCount = 0;
char pageAdd[64];


const int buttonPin = 2;


void setup() {

Serial.begin(9600);
// disable SD SPI

pinMode(4,OUTPUT);
digitalWrite(4,HIGH);


pinMode(buttonPin, INPUT);


Serial.println("Starting ethernet…");
Ethernet.begin(mac, ip);

Serial.println(Ethernet.localIP());

delay(2000);
Serial.println("Ready");

}

void loop() {

if (systemState == 0){
pushButton();
}

}

byte getPage(IPAddress ipBuf,int thisPort, char *page)
{
int inChar;
char outBuf[128];

Serial.print(F("connecting…"));

if(client.connect(ipBuf,thisPort) == 1)
{
Serial.println(F("connected"));

sprintf(outBuf,"GET %s HTTP/1.1",page);
client.println(outBuf);
sprintf(outBuf,"Host: %s",serverName);
client.println(outBuf);
client.println(F("Connection: close\r\n"));
}
else
{
Serial.println(F("failed"));
return 0;
}
// connectLoop controls the hardware fail timeout

int connectLoop = 0;

while(client.connected())
{
while(client.available())
{
inChar = client.read();
Serial.write(inChar);
// set connectLoop to zero if a packet arrives

connectLoop = 0;
}

connectLoop++;
// if more than 10000 milliseconds since the last packet

if(connectLoop > 10000)
{
// then close the connection from this end.

Serial.println();
Serial.println(F("Timeout"));
client.stop();
}
// this is a delay for the connectLoop timing

delay(1);
}

Serial.println();

Serial.println(F("disconnecting."));
// close client end

client.stop();

return 1;
}


void pushButton(){
if(digitalRead(buttonPin) == HIGH){


sprintf(pageAdd,"/siren"); (!getPage(server, serverPort, pageAdd));
Serial.println("Button pressed");
systemState == 1;

}
}
