Basic Web Buttons Using Ethernet Shield

I have a working text button, but would like to make a more realistic button.

Working Button:

client.println("<a href=\"/?center\"\">CENTER</a>");

This is the button I am trying to get working:

client.println("<input type=submit name=center value=\"CENTER\">");

You didn’t mention what’s not working…

One thing worth fixing: unless you close the input tag, your browser may get cranky. Note carefully the extra / at the end, just before the closing ‘>’:

client.println("<input type=submit name=center value=\"CENTER\"/>");

Thanks! Yea, I guess I should have explained things a bit better. The first code example works great, but i want to replace it with the second code example. The first code is a text (link type) button, and the second code is a real button with text in it. The second piece of code shows up on the web page, but it does nothing. From my understanding it should work, but I am missing something. Since I am replacing one piece of code for another, I made sure to comment out the other. Can anyone please HELP.

My whole web page.

          client.println("<h2> REMOTE SWITCH: </h2>");
          
          //client.println("<input type=range id=poop min=0 max=180 step=2 value=0>"); //Slider button for later
          
          client.println("<input type=submit name=center value=\"CENTER\"/>");

         
         //Servo1 movement

          //client.println("<a href=\"/?center\"\">CENTER</a>"); 
          client.println("<a href=\"/?left\"\">LEFT</a>");

Server button test code.

//zoomkat 8-04-12
//simple button GET server code to control servo and arduino pins 5, 6, and 7
//for use with IDE 1.0
//open serial monitor to see what the arduino receives
//use ' instead of " in the html 
//address will look like http://192.168.1.102:84 when submited
//for use with W5100 based ethernet shields

Thanks zoomkat, this is exactly what I was looking for, +1 for you!!!
