Hello

I read in a PHP book (written tin 2001) that I could set up variables by using the URL:

eg: http://www.primoweb.biz/index.php?name=hamish

Then, in that index.php file, I would have a bit which says

hello, <?php echo ("$name"); ?> and it would work.

Now, I am trying to cut a chunk of code out of my websites by doing the same thing for my page titles:

http://www.primoweb.biz/index.php?title=Homepage

and in the <title></title> tags for the page I could call the variable "$title" and it would print the word "Homepage".

However, I have tried this unsuccessfully.

Is this because this command is out of date? (it is an old book I saw it in) or is it because the variable is in the wrong place?

Thanks for any suggestions
Hamish

Try changing the php code to

PHP Code:


			
<?php echo $_GET['$title']; ?>

This should do it...

PHP Code:


			
<?php 

$title = $_GET['title'];

echo "<title>$title</title>";

?>

Hey

I tried that, but I wonder if the problem is the position of this variable on the page. Below is the part of my page which calls this variable:

PHP Code:


			
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">

<HTML>

<HEAD>



<title>

<?php

$title = $_GET['$title'];

echo "$title";

?> 

</title>



<link rel="stylesheet" type="text/css" href="style.css">



</HEAD>



<BODY>

    <div class="container"><!-- insert container - this div is closed at the end of the specific pages -->

        <div class="clear"></div>



    <!-- start left menu -->



<div class="left">



<ul id="nav">

    <li><a href="index.php?title=Homepage" title="Home Page">Home Page</a></li>

    <li><a href="about.php?title=About_Me" title="About Me">About Me</a></li>

    <li><a href="music.php?title=Music" title="Music">Music</a></li>

    <li><a href="#.php" title="">Other Links</a></li>

</ul>





    <!-- end menu -->

</div> <!-- left -->





<div class="main"><!-- starts on this page and finished on the individual pages -->



<div class="top"><img id="logo" src="./images/blah.gif" height="90px" width="320px" alt="Welcome to blah"></div>



break" src="./images/break_pink.gif">

This page top.php is included in the rest of the pages at the top of the page.

I wonder if the fact that the menu is further down the page than the "echo "$title"" would affect it. I guess it shouldn't given that the page should get the variable $title from the URL itself.

I wonder if the reason it isn't working is a silly mistake on my part.

Any suggestions?

Thanks again
Hamish

Hey Hamish,

You don't need the $ to refer to variables in a querystring or POST request. Therefore:

<?php echo $_GET["title"] ?>

should work for you.

If not, it might be that 'Superglobal' variables aren't available in the version of PHP which you are using. Then you can try:

<?php echo $HTTP_GET_VARS["title"]; ?>

In either case, you don't use the dollar because the 'title' is just an array reference, taken from the Name/Value pair in the querystring, and not a *real* variable.

Hope this helps

Just realised that...

Stupid mistake

Thanks stigthew

Both of the codes you gave me work. Thank you very very much for this - i reckon that I can cut about 20 lines out of all my pages!

thanks
