If you use Javascript you can set the FORM ACTION to call a function
within the same file (or at least within a *.js file that was
previously loaded into that file). Can you do something similar for
PHP? The code below (which I got from http://www.webmonkey.com) is
supposed to do this, but it doesn't work for me.
So I'm clear on this -- when this runs as there is no variable called
$submit the if true part will not execute, but instead the if false
(=else) part will run instead, showing the HTML FORM. This is indeed
what happens. But I understand that the code in the action attribute
(ie <?php echo $_SERVER['PHP_SELF']; ?>) will cause the file to be
reloaded. However as the user has clicked the submit button the
variable $submit will now have a value and so the if true part of the
if statement will execute.
It doesn't work for me -- I put data into each of the fields and then
click the button. The data disappears, but I don't get the
'name=value' list that I was expecting.
Is this valid code? If so why isn't it working? If not, what do I need
to do to change it?
Any help will be appreciated.
<html>
<body>
<?php
if ($submit) {
// process form
while (list($name, $value) = each($HTTP_POST_VARS)) {
echo "$name = $value<br>\n";
}
}else{
// display form
?>
<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
First name:<input type="Text" name="first"><br>
Last name:<input type="Text" name="last"><br>
Address:<input type="Text" name="address"><br>
Position:<input type="Text" name="position"><br>
<input type="Submit" name="submit" value="Enter information">
</form>
<?php
}
?>
</body>
</html>
