Lightbox 2 Wordpress Plugin
Wordpress plugin used to overlay images on the current page into neat Javascript-powered overlay popups.
16-12-2008 – Version 2 is out! Now from settings you can choose background-color, overlay opacity, resize speed and automatically add the lightbox effect to your post’s images.
This plugin includes the new Lightbox JS v2.0.4 javascript written by Lokesh Dhakar and and was then transformed into a Wordpress Plugin by me. Use a title attribute if you want to show a caption. Click on the images below for an example.
- 29-07-2007 – See also the new Slimbox Wordpress Plugin, a 7kb clone of the popular Lightbox JS
- I added the digg it button, please DIGG ME!
Upgrade
- De-activate the plugin.
- Delete the old version `lightbox-2-wordpress-plugin` directory.
Installation
- Unzip the `lightbox-2-wordpress-plugin.zip` file.
- Upload lightbox-2-wordpress-plugin folder to the /wp-content/plugins/ directory.
- Activate the plugin through the ‘Plugins’ menu in WordPress, go to Setting->Lightbox.
- Add a rel=”lightbox” attribute to any link tag to activate the lightbox, or rel=”lightbox[roadtrip]“ for an image set.
- Optional: Use a
titleattribute if you want to show a caption.
Single example:
<a href=”img1.jpg” rel=”lightbox” title=”my caption”>thumbnail1</a>
Image set example:
<a href=”img1.jpg” rel=”lightbox[roadtrip]“>thumbnail1</a>
<a href=”img2.jpg” rel=”lightbox[roadtrip]“>thumbnail2</a>
<a href=”img3.jpg” rel=”lightbox[roadtrip]“>thumbnail3</a>
Tnx to my sister for the photos! Link me in your site!

I did a new version 2 of my plugin with many features, who wants to test it can contact me here.
1. Your contact form seems to be broken?
2. Hi,
I’m currently using your lightbox 2.0 plugin but it doesn’t work on inserted galleries? I have WP 2.7 installed. Any clues?
Check this page and you’ll see what I mean. All the thumbs are meant to be opened with Lightbox.

Hi pierre, have u added the rel=”lightbox”?, try the automatic setting, redownload the plugin because i make a change..
Version 2 out, say me if it is all ok.
SimoneCiao,
ho notato che in plugin.php righe 51-54 sono presenti gli slash di chiusura dello script, ma in tal modo il codice non è validato. togliendo lo “/” va tutto a posto
ciao!
MikeI have the same problem as Pierre, even with the automatic option this new version doesnt open the Lightbox!
BTW – Awesome work with this plug-in, I have been using the previous version and it’s great!
I upgraded it, activated and was not pleased. And disabled it and downgraded.
Old version instructions…
“4. If you want to add automatically the lightbox effect to your post’s images, open lighbox.php and remove the comment ‘//’ from lines 21 to 24.”
This no longer exist. Is there any fix? Since my old site were all automatic Lightbox right away and were soooo many images. Now all of them do not work. 
I will also try to study your code once I have the time.
Thanks
KVHi.
I noticed that the new version doesn’t add the necessary JavaScripts to the header (prototype, scriptaculous etc), which is why Lightbox isn’t working.
Can you please check if the codes add_action(‘wp_head’, ‘lightbox_display_hook’); and anything related are correctly done?
Thanks in advance.
Plz link me your link problem and you wp version.
I noticed the same problem as ‘KV’ witrh the new version (2.0.1)
The header doesn’t contain any lightbox specific needs.
look e.g. here: http://www.duerrbi.de/2007/05/26/eingebildeter-besucher/
Working with wp 2.7
KVI am also using WP2.7, but I cannot give you a link since it’s a locally hosted test site.
With the previous version, all the JavaScripts were added to the header, while the new version doesn’t.
It seems like “function lightbox_wp_head” (lines 42-57 in lightbox.php) isn’t working.
@Duerrbi: hi man in homepage you have the code, check your settings.
FrankNice upgrade, all work for me.
Excellent! now we just need a link to the zip file…..
XXX never mind, I found it hiding at the bottom of the post after all the old changelogs.
@Peppe
After restoring the default options and saving again, the header now contain all lightbox needs to run. weird
Simonetoo bad I wrote in italian, sorry, I was in a hurry…
I noticed that in lightbox.php, lines 51 – 54 the script tag is closed this way
echo ‘<script type="text/javascript" src="’ . $lightboxpluginpath . ‘lightbox/js/prototype.js" /></script>’."\n";
echo ‘<script type="text/javascript" src="’ . $lightboxpluginpath . ‘lightbox/js/scriptaculous.js?load=effects,builder" /></script>’."\n";
echo ‘<script type="text/javascript" src="’ . $lightboxpluginpath . ‘lightbox/js/prototype.js" /></script>’."\n";
echo ‘<script type="text/javascript" src="’ . $lightboxpluginpath . ‘lightbox/js/lightbox.js" /></script>’."\n";
but that doens’t validate, it should be
echo ‘<script type="text/javascript" src="’ . $lightboxpluginpath . ‘lightbox/js/prototype.js"></script>’."\n";
echo ‘<script type="text/javascript" src="’ . $lightboxpluginpath . ‘lightbox/js/scriptaculous.js?load=effects,builder"></script>’."\n";
echo ‘<script type="text/javascript" src="’ . $lightboxpluginpath . ‘lightbox/js/prototype.js"></script>’."\n";
echo ‘<script type="text/javascript" src="’ . $lightboxpluginpath . ‘lightbox/js/lightbox.js"></script>’."\n";
cheers
Tnx simone, commited (i’m italian)
D4m4geHi,
Nice work, but does not seem to work with Internet explorer…, I get a script error.
Downgraded back to 1.8.2, works fine again.
Tnx d4m4ge: download the new version, there was an error: i included the prototype twice.
D4m4geIt works! thanks, excellent work!
The prototype and scriptaculous libraries are causing conflicts with existing references.
Use wp_enqueue_script() to ensure that they are referenced only once.
ok
Sorry, in version 2.0.2, lightbox.php -> line 48:
if ($lightboxoffmeta == “false”) {
but, not working for me, it would be like this:
if (!$lightboxoffmeta == “false”) {
in order to print the <script’s… code into section…
@Pepe Montfort
thanks for the fix 
The “Auto-lightbox” setting is messing with the caption. If i enabled “auto-lightbox”, my caption for the image (as set in title=”xxxxx”) will not be displayed for an image that already has its image set (as set in rel=’lightbox[xxxx]‘).

Sorry, me again. I found exactly the trouble. The new wp post_meta “lightboxoff” is not set to any post published previous to the new version of this plugin, so, in order to skip this, the 48 line of lightbox.php must be:
if ($lightboxoffmeta !== “true”) {
With this fix, the plugin must be working for new posts and old posts. Merry Christmas!
@Pepe Montfort: hi leave the line i did, and add this line before (47)
$lightboxoff = false;
say me if work

If found a bug in the lightbox_wp_head() function. The conditional reads:
if ($lightboxoffmeta == “false”) { …
In order for lightbox to be loaded on pages on my site which were created before the plugin existed, the conditional needs to be:
if ($lightboxoffmeta == “false” || $lightboxoffmeta == “”) { …
Thanks for a great plugin.
@Lee: plz read my previous comment or re-download the plugin.
mmm… not working:
get_post_meta($post->ID,’lightboxoff’,true);
get_post_meta does not receive defaults values trough $lightboxoff, so, when we try to get the post_meta value of lightboxoff from a post where is not set the post_meta, the $lightboxoffmeta is set to NULL.
I think that default values is a better way to programming, but, get_post_meta take the default value to the trash… i like frameworks like symfony because they keep in mind that default values must be set in the same “get” functions, but, is not the case in wordpress…
ps. sorry for my poor english 
have u tried to add $lightboxoff = false;
or re-download the plugin.
Both of them. Even i tried to set a default value directly for $lightboxoffmeta. The trouble is in the “get_post_meta” function, it is setting the $lightboxoffmeta value to Null or empty for old posts who has not set the new lightbox-js post_meta…. in my blog there are more than 200 posts in this situation, well, another answer could be to make an installer function to the plugin for set the new post_meta to older posts, but maybe it could not to be the better way…
@Pepe: hi, for me it works, i don’t know why not for you: adding $lightboxoff = false; if the get_post_meta is null it automatically use value false, so in the old post the $lightboxoffmeta is false. I added you to gtalk, tomorrow contact me so we can try some test.

Hi,
i installed the lightbox 2 plugin on my wordpress 2.7.
It works great in Firefox, but does not work in IE and/or Chrome. You can try it yourself at www . defilosoof . org / cms / category /featured
Do you have any idea what can be a solution to get it to work? Thanks in advance!
Tom
Maybe you should put “Avvertimi via email quando qualcuno risponde al mio commento.” in English, so that we ALL are aware of the consequences!

Any ideas how I can make this work for each individual image in an Image Gallery, as opposed to each individual image placed in a post?
