Hi,
I'm looking over some code trying to teach myself
and was wondering what gid=314 was here...

<a class="headline" href="javascript

opUp('http://www.blah.info/blah/gallery.php?gid=314', 'Gallery', '519',
'500')">Heading</a></b><br>Sub Heading

What is gid and what is the 314?

Anybody know?
Cheers,
Dal79

gallery id

He has just named his id field in the database gid thats all it is.

You can name it anything.

You must of learn Access at some point?

An id field signifies each record in a table.
id
1
2
3
etc.

You can name the id field whatever you want.
So the url basically fetches record number 314 and displays the info.

It doesn't have to represent an SQl table. It could represent a file called "1.html", or "1.php".

Take this code, for example:

PHP: Select all


<?php
 
if (!empty($_GET['gid'])) {
 
 $gid = $_GET['gid'];
 
}
 
else {
 
 $gid = 1;
 
}
 
if (file_exists("importantstuff/" . $gid . ".php")) {
 
 include("importantstuff/" . $gid . ".php");
 
}
 
else {
 
 include("404_error.php");
 
}
 
?>

Just a nice little (heh) example for you. It basically checks whether the GET['gid'] parameter has a value, if it does, turn it into a variable and include a page if it exists.

Hope that helps.

Some confusing explanations there for you. It's alot simpler than all of that. It's a variable that he's passing between pages. 'gid' is the variable name, and '314' is the value of that variable.

You can access the variable by using

PHP: Select all


$_GET['gid'];
