Usage

Fill out the form below for each gallery you want to include, with a unique name for your supergallery.

This extension defaults to four pairs of gallery inputs, unless the number of galleries in your intended supergallery is passed as this page's parameter, for example for five galleries:

http://localhost/wiki/index.php/Special:SuperGallery/5

The galleries you link to will be created if they do not exist, and can themselves be made as usual using the gallery tag.

Here is the expected form of the picture url and the article link:

http://localhost/wiki/images/d/de/Boat.jpg

[[Pictures_of_Auckland|Pictures of Auckland]]

Press the Submit Query button. A new page will be generated under your unique title, with a supergallery tag and your posted information, which you can edit.

Page Setup

What is the title of your supergallery? This is a compulsory field.

<input name='wpGtitle' size = '35' />

How many columns do you want the supergallery to have (up to 3)? If you leave the field empty it is 2.

<input name='wpColumn' size = '10' />

How wide do you want each thumbnail to be? Empty field is 120.

<input name='wpWidth' size = '10' />

How high do you want each thumbnail's box to be? Empty field is 200.

<input name='wpHeight' size = '10' />

How wide do you want the supergallery's border to be? Empty field is 1. No border is 0.

<input name='wpBorder' size = '10' />

What color do you want the supergallery's border to be? Empty field is #cccccc.

<input name='wpBorderColor' size = '10' />

What do you want the supergallery's margin to be? Empty field is 2.

<input name='wpTableMargin' size = '10' />

How much cellpadding to you want? Empty field is 20.

<input name='wpCellPadding' size = '10' />

What color do you want the supergallery's background to be? Empty field is #ffffff.

<input name='wpBackgroundColor' size = '10' /> <input type='hidden' name='wpParam' value=$par>

" );

# Render multiple inputs using the /$par from the url for ($ctr = 1; $ctr <= $par; $ctr++) { $wgOut->addHTML(

"

Gallery " . $ctr ."

The full URL of the image you want for the thumbnail.

<input name='wpUrl" . $ctr . "' size = '50' />

The caption for this gallery, which is also its link.

<input name='wpCaption" . $ctr . "' size = '50' />" ); }

# Post $wgOut->addHTML( "

" . wfElement('input', array('name' => 'wpSubmit', 'type' => 'submit'))

. "</form>

When you submit this form, a supergallery page will be created with the name you specified, unless the name already exists. You can edit the tag in that page if you wish to change the supergallery.
