simple script:

PHP Code:


			
<?php



if ($submit == "click"){ 

  echo "Hello, $UserName"; 

} 

else{ 

  echo ' 

  <html><body> 



  <form method="post" action="input.php3"> 



  Enter Your Name 

  <input type="text" name="UserName"></input><br> 



  <input type="submit" name="submit" value="click"></input> 



  </form> 



  </body></html> 

  '; 

} 



?>

i got php 4.whatever.the.latest.is installed on Windows. im just running it on my local server just to mess around with it again.
anyways, the script is supposed to show the input form when accessed directly, and say Hello, whoever when it's submitted.

This is what i get when i run it:
Notice: Undefined variable: submit in C:\Program Files\Abyss Web Server\htdocs\test.php on line 3

Enter Your Name

if i do $_POST['submit'] i get "Notice: Undefined index: submit in C:\Program Files\Abyss Web Server\htdocs\test.php on line 3" and then it shows the form *(and if i click submit it shows the error, then says Hello, "

Try this:

Code:

<?php

	if (in_array('submit', $_POST)){ 
		echo "Hello, $_POST[UserName]";
	} else {
		echo ' 
<html>
	<body> 
		<form method="post" action="input.php3">
			Enter Your Name <input type="text" name="UserName"></input><br> 
			<input type="submit" name="submit" value="click"></input> 
		</form> 
	</body>
</html>'; 
	} 

?>
