[SOLVED] two button form

hi all,

 

i'm trying to make a two button form.. exactly like this one

<?php

echo "<h1> Hello $name </h1>";

if ($action == "b1")
echo "you just clicked button 1";
if ($action == "b2")
echo "you just clicked button 2";

?>

Thats because $action is not defined in this php file. Define action before the if statements and it will work

Like this:

 

<?php

if(isset($_POST['action'])) {
$action = $_POST['action'];
$name = $_POST['name'];

echo "<h1> Hello $name </h1>";

if ($action == "b1")
	echo "you just clicked button 1";
if ($action == "b2")
	echo "you just clicked button 2";
}

echo '
<form  method="post" action= "testpage.php">
Name : <input type="text" name="name" size="30" value="" maxlength="60"/><br /><br />
<input type="submit" value="b1" name="action" />
<input type="submit" value="b2" name="action" /><br /><br />
</form>';
?>

You first need to get the POST data from the form.

 

<form action="my_form.php" method="POST">
 <p>Name: <input type="text" name="name" /></p>
 <p>
   <input type="submit" name="submit" value="Go" />
   <input type="submit" name="submit" value="Cancel" />
 </p>
</form>

 

my_form.php

<?php
$action = $_POST['submit'];

if(isset($action)) {
 switch ($action) {
   case 'Go':
     print 'Hello ' . $_POST['name'] . ', you hit ' . $action;
     break;
   case 'Cancel':
    print 'Hello ' . $_POST['name'] . ', you hit ' . $action;
    break;
 }
}
?>

That script was relying on register_globals. >_>

Bloody globals!! *raises fist*

More wasted time due to register_globals... Laughingly, register_globals were created to save a little typing time for lazy programmers. The problems with them have easily cost a thousand times more wasted time then what they ever saved in typing time.

 

Register_globals were depreciated and turned off long ago in php4.2 in the year 2002. No new code, new books, new tutorials, or new hosting accounts should have been created after that point in time that used register_globals. Register_globals have been completely eliminated in upcoming php6.

 

That site is doing you and anyone else who finds it a huge disservice by listing code that is dependent on register_globals, a full six years after all programmers should have stopped using register_globals.

ic that explains why they weren't listing having to intiate the variables.. on the link...
