Get was not set

$Value = "";
if(isset($_GET['submit']))
{
$Value = $_GET['submit'];
}
switch ($Value) {

praeto · October 31, 2007

Do I place your code in front of the switch _get?? I tried that but received an error. PHP Parse error: syntax error, unexpected T_SWITCH, expecting T_CASE or T_DEFAULT or '}'

So I took out the $Value = $_GET['submit']; and it ran without error however the rest of the code didnt work "print 'Button1 was clicked.';

"

<?php
$Value = "";
if(isset($_GET['submit']))
{
$Value = $_GET['submit'];
}
switch ($Value) { 

switch ($_GET['submit']) { 

    case 'Button1': 
      print 'Button1 was clicked.';
      break; 

    case 'Button2': 
      print 'Button2 was clicked.'; 
      break; 

    case 'Button3': 
      print 'Button3 was clicked.'; 
      break; 

    default: 
      print ' 
        <form> 
            <input type="submit" name="submit" value="Button1" /> 
            <input type="submit" name="submit" value="Button2" /> 
            <input type="submit" name="submit" value="Button3" /> 
        </form>'; 
      break; 

  } // End: switch ($_GET['submit']) 
  
# END buttons that do different things example

switch ($Value) { 

switch ($_GET['submit']) {

should be just

switch ($Value) {

No buttons display when I tried your code...

<?php
if(isset($_GET['submit'])){//check if set
 switch ($_GET['submit']) { 

	case 'Button1': 
	  print 'Button1 was clicked.';
	  break; 

	case 'Button2': 
	  print 'Button2 was clicked.'; 
	  break; 

	case 'Button3': 
	  print 'Button3 was clicked.'; 
	  break; 

	default: 
	  print ' 
		<form> 
			<input type="submit" name="submit" value="Button1" /> 
			<input type="submit" name="submit" value="Button2" /> 
			<input type="submit" name="submit" value="Button3" /> 
		</form>';

All I am trying to accomplish is to make a menu to be able to pick from 3 button choices. Once the choice is made and button pressed the command is ran.

Currently my webcam page plays a wav file when the page is loaded allerting me that someone is watching my cam. I would like to take it a step further and place buttons on my page with 3 different phrases to say (I will record seperate wave files).

I just dont know how to do it in PHP. Somewhere in the code we are working on we should be able to do what I mentioned. Any help is appreciated.....

Still does nothing..

teng84 · October 31, 2007

sorry im out of this thread seems like your not doing anything and living it to a forum member

again sorry.....

praeto · October 31, 2007

Im asking for HELP, not leaving it for a forum member as you stated. I have 95 percent of the code already written and just need that extra 5 percent to make it work.

I have no knowledge of PHP and turned to the members of PHPFREAKS to help me out. I searched to try to get the answer, I tried your code but it simply didnt work.

Please dont give up on my question/issue...

Praeto - have you explicitly set the method to GET in your HTML form? If not, it will be POSTing and not GETing (as that's the default). In which case, simply change your instances of $_GET to $_POST and you're sorted.

praeto · October 31, 2007

It seems that my webserver (Webweaver) is to blame for the code not working correctly. I am able to run PHP on it however it wont run this script for some reason.

I found this out once I ran the same script on another server program (Apache) and it ran fine.

Thanks for all that replied.
