form input -&gt; link output

form input -> link output

thepeccavi

I am trying to create a script that takes form input (textbox) and then sends the form input to itself (<?=$SERVER['PHP_SELF']?>) and then (it checks everytime) if($POST['submit']==true) it prints <a href="<?=$_POST['location']?>">Right click...</a> and then the form again...

This is the full code:

<html>
<head>
<title>Nick Flashes version 2 - ThePeccavi.co.uk</title>
</head>
<?php
if($_POST['submit']==false){
?>

<body>
<h1>Welcome to ThePeccavi's Nick Flashes version 2</h1>
<p>
This uses PHP to put your input into a link :-)
</p>
Put in the location (eg http://asite.com/flashdirectory/directory/flash.swf), this can be an html, php, javascript, pdf, any document on the web:<form action="<?=$SERVER['PHP_SELF']?>" method="post">
<input type="text" name="location">
<input type="submit" value="Nick Flash!">
</form>
</body>
<?php
}
elseif($POST['submit']==true){
?>
<body>
<h1>Welcome to ThePeccavi's Nick Flashes version 2</h1>
<p>
This uses PHP to put your input into a link :-)
</p>
Your Link:
<a href="<?=$_POST['location']?>">Right click and then click Save Link (or Target) as... then you can save the file on your computer and there you go!</a>

<br />
Go again?
<form action="<?=$_SERVER['PHP_SELF']?>" method="post">
<input type="text" name="location">
<input type="submit" value="Nick Flash!">
</form>
</body>
<?php }?>
</html>

to see it in action go to http://thepeccavi.co.uk/nickflashes2.php

It fails because you haven't given the submit input a name attribute, thus "$_POST['submit']" doesn't exist.

This should work:

$html  = '<html><head>' .
         '<title>Nick Flashes version 2 - ThePeccavi.co.uk</title>' .
         '</head><body>';
$html .= '<h1>Welcome to ThePeccavi\'s Nick Flashes version 2</h1>' .
         '<p>This uses PHP to put your input into a link :-)</p>';

if (!isset($_POST['submit'])) {
    $html .= 'Put in the location ' .
             '(eg http://asite.com/flashdirectory/directory/flash.swf), ' .
             'this can be an html, php, javascript, pdf, any document on the web:';

} else {
    $html .= 'Your Link: ' .
             '<a href="' . $_POST['location'] . '">' .
             'Right click and then click Save Link (or Target) as... ' .
             'then you can save the file on your computer and there you go!</a>' .
             '<br />Go again?';
}

$html .= '<form action="' . $_SERVER['PHP_SELF'] . '" method="post">' .
         '<input type="text" name="location" />' .
         '<input type="submit" name="submit" value="Nick Flash!" />' .
         '</form>';
$html .= '</body></html>';

echo $html;
