Quick PHP Help?

[delude]

So basically I have a single field form, and I want whatever is inputted into the field to be added on to the end of a link, example:

User input='100'

URL = 'http://www.website.com/999&extension=100


Currently I have this in my index.php file:

form action="submit.php" method="post">
<input name="FieldName" type="text"  />
</div>
<input type="image" src="image/source.jpg" width="x" height="x" />
</form>

And in 'submit.php' I have this:

<?php
// Change to the URL you want to redirect to
$URL="http://www.website.com/999&extension= $_POST["FieldName"];

header ("Location: $URL");

?>

Obviously this doesn't work as I wouldn't be asking for help, and I also have absolutely no idea about PHP, this is my first go at trying to write something myself.

Maybe it would be better to get rid of submit.php completely? I can take out the '$_POST["FieldName"]' part and just put text or a number and it works fine, but I want it to use the value that the user has typed into the form field.

Any help will be much appreciated!
Thanks

Sorry, could this please be moved to technical help?

There are two main issues that I can see with your code.

Issue one is that there is no opening < on the form tag in your HTML. To be honest I'm guessing that you have included this, and it just got cut out in the copy/paste, but I thought I'd mention it just to make sure.

The second problem is that you have no closing " quote at the end of your $URL definition. The corrected code is:

<?php
// Change to the URL you want to redirect to
$URL="http://www.website.com/999&extension={$_POST["FieldName"]}";

header ("Location: $URL");

?>

Note the {} around the variable within the double quotes. This is not always required, but it is a way of telling PHP that the contents of the curly brackets is a variable. If it was a normal variable name, eg. $userid, you wouldn't have to include it (although it's good practice to anyway if you're using double quotes to enclose your string.) However, since your variable contains double quotes, PHP would error if you omitted the curly brackets, as a result of the additional ""s.

Hope that makes sense?

alternatively, appending using . would work:

<?php
// Change to the URL you want to redirect to
$URL="http://www.website.com/999&extension=" . $_POST["FieldName"];

header ("Location: $URL");

?>
