Specification
The user clicks on the link, intending to make a gallery page that itself links to galleries. A form pops up. It has eight (or so) sets of inputs boxes containing:
- url of thumbnail
- size of thumbnail
- link to sub-gallery
- caption about sub-gallery
- border
- padding
The form also has:
- title of supergallery
The extension needs to know if this is a user's private supergallery, so it can append /username to its url. The extension itself uses gallery tags and css backgrounds to create the page for the user. It auto-places each sub-gallery "cell" depending on how many the user specifies by filling in sub-gallery details on the form.
No Ajax is needed, as the submit button creates the page.
I have a working example of this as a page, see http://jack.co.nz/Galleries

Coding Issues
Heading offline, will do this now as much as possible, got the latest updates to the template, compiles OK locally, back online 3 days time maybe -- Jack 15:22, 29 November 2008 (NZDT)
Serialization
The output of this extension needs to be serialized so it can be the contents of a tag function in a new page. Also, a new input is needed in the form for the name of the new page. Here is a good article about serializing objects: http://www.devshed.com/c/a/PHP/The-Basics-of-Serializing-Objects-in-PHP/ --Jack 10:27, 10 December 2008 (NZDT)
Nice simple example:
<?php
class dog {
var $name;
var $age;
var $owner;
function dog($in_name="unnamed",$in_age="0",$in_owner="unknown") {
$this->name = $in_name;
$this->age = $in_age;
$this->owner = $in_owner;
}
function getage() {
return ($this->age * 365);
}
function getowner() {
return ($this->owner);
}
function getname() {
return ($this->name);
}
}
?>
<body bgcolor=white>
<h1>Beware the dog</h1>
<?php
$ourfirstdog = new dog("Rover",12,"Lisa and Graham");
$dogdisc = serialize($ourfirstdog);
$pet = unserialize($dogdisc);
$old = $pet->getage();
$name = $pet->getname();
print "Our first dog is called $name and is $old days old<br>";
print $dogdisc;
