Access form variables within form

chemaster

I want the user to enter TEXT is a textbox and hit submit. On sumbit the user will be directed to http://www.mydomain.com/TEXT/

Tried the following:

<?php print($gallery);?>
<?php echo $gallery;?>

I've tried echo and print and neighter works. Here is the body part below: Any suggestions? I'm being directed to http://www.mydomain.com and not http://www.mydomain.com/TEXT/

<body>
<form name="form1" method="post" action="">
<input name="gallery" type="text" id="gallery">
<input name="Submit" type="submit" onClick="MM_goToURL('parent','http://www.mydomain.com/<?php print($gallery);?>');return document.MM_returnValue" value="Submit">
</form>
</body>
</html>

<?php 
   print($_POST["gallery"]);
?>

Newer installs, and savy installs of older versions of PHP, have the register_globals directive turned off. This was a huge security hole and it is best that it is turned off. So you need to access your variables by how they are submitted to the page. Since you form uses POST as it's action your variables are in the special system array $_POST.

Your suggestion seemed to work the first time but not again. I have closed my browser and retried without success. Any suggestion would be appreciated.

I figured out want is happening but not a solution.

I must type in the text and hit 'Enter' on the keyboard AND then click on 'Submit'.

Any thoughts on how to get this to work without the need of using 'Enter' on the keyboard? I only want to click on 'Submit'.

Sorry I didn't look completely at your example.

What you are doing either requires Javascript, or an intermediate page.

Since I dispise Javascript I'll show you what you need to do with an intermediate page.

<!-- Form Page -->
<body>
<form name="form1" method="post" action="formSubmit.php">
<input name="gallery" type="text" id="gallery"> 
<input name="Submit" type="submit" value="Submit"> 
</form> 
</body> 
</html>

<?php
// formSubmit.php
header("Location: [url]http://www.mydomain.com/[/url]" . $_POST("gallery"));
?>

However what you are doing doesn't need any php if you just get the Javascript correct for your OnClick event that you already have.

You need to remember that PHP is a server side language, that means that it is only "running" on the server. When someone is viewing a page that means that PHP has completed running. PHP is only operating on page generation. If you don't understand what I just said you are going to have to look up exactly how the web is structured, and what is ment by a "stateless environment" and do a bit of reading in the php manual.

I get the following error:

Parse error: parse error in /home/virtual/site3/fst/var/www/html/formSubmit.php on line 3

Anyway, thanks for your help, I will do some more reading to see if I can figure this thing out.

Thanks,

Oops, my bad, it's a typo, I wasn't paying attention to my quotes. And the form wants to add it's own code to the url.

<?php 
// formSubmit.php 
header("Location: http://www.mydomain.com/" . $_POST("gallery")); 
?>

That should work.
