Dynamic hyperlinks

AlGale

Hi guys.

I am trying to create a list of dynamic hyperlinks that will then pass the correct parameters to the next page. I am extracting a list of story titles from a database, and creating a table via a standard "while" loop.

The code I am so far putting into one of the table cells is:

<td width=\"200\"><a href=".'Stories.php?' . $row["Title"] . ">$Title</a></td>

This doesn`t produce any errors, and does indeed call the intended page, so I think the error may be in the way I am pulling this passed parameter in on the target page. I have tried using GET:

$Title = $_GET["Title"];

But I know this is a form function, not a hyperlink one. So how do I get this to work? I know I could create form buttons to do it - Ive done that in the past - but this time Id like to learn how to generate these dynamic hyperlinks.

Thanks in advance guys.

If you're passing variables via the query string in a URI, you're effectively using the HTTP GET method.

There is no distinction between using a form and using the URI here.

Oh - ok, thanks for that - so why isn`t the script above working?? Any idea what I1m missing??

Al, as you try to access the parameter by its name "Title" on the second page, the links may miss the parameter name. Try
<a href=".'Stories.php?Title=' . $row["Title"] . ">

Hi xblue,

Thanks for that. I used:

<td width=\"200\"><a href=".'Stories.php?Title=' . $row["Title"] . ">$Title</td>

and get sent to

www.mysite/Stories.php?Title=Title

as expected - but still nothing gets pulled through - and yes, I do have test data in the db that should be picked up.

Cheers for your help so far though....

Let's test with 2 pages, pagetest.html and displaytest.php

<!-- pagetest.html -->
<a href="./displaytest.php?title=MyTitle">Display MyTitle</a>

<?php
//displaytest.php
if (!empty($_GET['title'])) {
	echo "Title: " . $_GET['title'];
} else {
	echo "No title specified";
}
?>

Nice bit of code! I used the php part on my existing page, and it`s telling me there is no title specified - so for some reason, nothing seems to be being passed!!!

AlGale

No - cancel that! It was capitelisation - title not Title.

OK, so that is working - must be a problem with MySQL, not the PHP.

Many thanks guys (and Gal!)

yes if $row["Title"] remains empty then probably there is something wrong with the query. so, you don't see it in the url on the second page?

one thing I just noticed: you seem to be missing the quotes around the href attribute (would only make a difference if what is supposed to come from the database contains spaces, but it is cleaner to add them anyway)

echo "<td width=\"200\"><a href=".'Stories.php?Title=' . $row["Title"] . ">$Title</td>";

I'd concaatenate like that

echo '<td width="200"><a href="Stories.php?Title=' . $row["Title"] . '">' . $Title . '</td>';

and don't forget to close the <a> tag

Excellent!!! Thanks for that - all works a treat now. Thanks guys!
