Zen Lightbox addon [Support Thread]

[Woodymon]

@Izon: Just a hunch but maybe some other JavaScript you are loading is conflicting? Maybe temporarily disable the other scripts to test.

The other two loaded scripts:

<script type="text/javascript" src="js/kuzmenu.js"></script>
<script type="text/javascript" src="js/rollovers.js"></script

I'm not familiar with kuzmenu.

See here:

You have a mouseover enabled on the additional image (the drawing thrumbnail) which maybe conflicting with Lightbox function. Disable the mouseover on that image to test for conflict. (easiest to test by temporarily disabling rollover script).

Woody,

Thanks for your efforts. I wish I could go back to the original developers but that's not an option. I'm not familiar with kuzmenu either and could not find anything online.

I guess it could be a javascript conflict, but I would expect to see some sort of error message.

The other reason I question this is that, when I look at the source code, for the image popup, I see

  <a href="images/RSM-1-7501.jpg" target="_blank">(Larger image)</a>

I would expect to see something similar to this

<!-- begin lightbox v1.1 aclarke 2006-09-06 -->
<script language="javascript" type="text/javascript"><!--
document.write('<a href="images/scl/novar-75mm.jpg?zenid=e12b280870a919e950bf31c29c2152e6" rel="lightbox[gallery]" title="Novar Anastigmat lens 3.5/7.5cm"><img src="images/scl/novar-75mm.jpg" alt="Novar Anastigmat lens 3.5/7.5cm" title=" Novar Anastigmat lens 3.5/7.5cm " width="133" height="120" /><br /><span class="imgLink">larger image</span></a>');
//--></script>
<!-- end lightbox v1.1 aclarke 2006-09-06 -->

which is from the source of a working installation.

If it were a javascript conflict, wouldn't the code still get output correctly to the browser, then probably throw an error?

Given the above, I would think there is some problem with my install?

Again, I really appreciate your time and effort.

Just tossing out ideas:

I would still temporarily disable the rollover and kazmenu one at a time to see if there is any conflict.

And you sure you have:

Correctly edited Zen Cart core files to include Lightbox code:
includes/templates/classic/templates/tpl_modules_main_product_image.php
and
includes/modules/classic/additional_images.php

And uploaded
includes/modules/pages/product_info/jscript_lightbox.php
includes/templates/template_default/jscript/lightbox_effects.js

And uploaded the lightbox gifs to
includes/templates/template_default/images/lightbox/

To test maybe temporarily remove:
includes/functions/extra_functions/zen_image_lightbox_IH2_url.php

Is there a compatibility issue with SEO URL's? Since I have not employed SEO URL's I cannot help. Hopefully someone whom has both Lightbox and SEO URL's installed can post to confirm they work together. Or maybe some SEO URL mod hints in this thread?

Good luck,
Woody

This sounds like the meat of the problem. I have not edited these files.

When I downloaded the contribution and decompressed it, I found a readme.txt file with 3 simple instructions, none of which mentions editing these files. Did I miss other instructions in this download?

I'll try looking back through this thread and see if I can find those instructions.

Thanks again for your help.

Feeling like an idiot here:

What core files need to be edited to include lightbox code?

This sounds like the meat of the problem. I have not edited these files. When I downloaded the contribution and decompressed it, I found a readme.txt file with 3 simple instructions, none of which mentions editing these files. .

You are correct. The readme is over simplified and does not include the code snippets which were merged into the core Zen Cart files provided in the mod package. (Unfortunately the developer assumes you will on your own compare the provided files with your installed versions. But many new to Zen Cart just blindly upload. This is why it is is best practice for developers to document such code snippets in the mod readme...but some mod developers are in just too much of a rush or just forget or just don't care).

At any rate this mod works with Zen Cart 1.37 but it has NOT been updated for Zen cart 1.37. Compare with the ZC 1.37 core files and you will observe differences in ZC 1.37 version of /includes/modules/additional_images.php that do not show up in the mod version of the same file.

Note the Lightbox 1.3 mod was last updated over six months ago, well before the release of ZC 1.37. Hopefully Alex will take this in consideration with next update.

So I just compared the two core ZC files provided in the Zen Lightbox 1.3 mod distribution with the Zen Cart 1.37 version core files.

My findings:

(1) \includes\templates\YOUR-TEMPLATE-FOLDER\templates\tpl_modules_main_product_image.php
in the mod package is still current with ZC 1.37

 * @version $Id: tpl_modules_main_product_image.php 3208 2006-03-19 16:48:57Z birdbrain $

(2) But I cannot say the same for:
\includes\modules\YOUR-TEMPLATE-FOLDER\additional_images.php

Latest Zen Cart 1.37 version:

 * @version $Id: additional_images.php 5369 2006-12-23 10:55:52Z drbyte $

Older IH2 version in Zen Lightbox:

 * @version $Id: additional_images.php,v 1.3 2006/05/01 12:20:31 tim Exp $

(keep in mind that cboylan integrated code from the last version of ImageHandler 2 into the Lightbox version of the file. Last version of IH2 was released in the early days of ZC 1.3x and the IH2 mod is no longer developed by the author).

Comparing this file I noted one specific line is for Lightbox and all the other changes are for IH2.

In the latest ZC 1.37 version of the file multiple instances of the ereg_replace() function has been replaced by str_replace() function.

For example, the following:

  $products_image_base = ereg_replace($products_image_extension . '$', '', $products_image); 

Was changed in Zen Cart 1.37 to :

  $products_image_base = str_replace($products_image_extension, '', $products_image); 

If you want to understand why see:
See http://us2.php.net/ereg_replace
http://us2.php.net/str_replace

So for this specific file if you don't use IH2 (and it appears you don't) it might be best to just open a copy of the default ZC 1.37 core version (if you have no other edits) and edit the one line difference yourself and then upload.

For the future I think it best if the lightbox mod was released in two separate versions, one for base Zen Cart and another for IH2 (just include alternative files in the same package but in different option directories, and also document the different code snippets in readme).

Also I am uncertain if non-IH2 users need to upload
includes/functions/extra_functions/zen_image_lightbox_IH2_url.php
It appears it is only needed for IH2 installs but I myself use IH2 so I have file uploaded.

I suspect some of this stuff may have been previously documented further back in this thread. Search on cboylan for more info.

As a reminder for all...

I'm not saying that uploading those files is your current issue (and it is likely not) but any time you install a mod you should not overwrite core files or upload overrides, without first checking if those files provided in the mod match your Zen Cart version. That applies to Lightbox also.

And before overwriting you should check to see if you will be overwriting files you have previously edited/customized.

Install a compare/merge tool (e.g. WinMerge or BeyondCompare) to compare the mod files with the Zen Cart core versions and also compare with the back ups of your versions (before you uploaded the mod versions).

Motti,

Find the Images folder where your product images are, and add images to it as follows:
If your main product image is productA.jpg , then additional images can be
productA_01.jpg
productA_02.jpg
etc...

As a matter of fact, you put anything you want after the underscore.
If you already have an underscore in the image name, then...., oh nooooo, it's kryptonite.

Make sure you have additional images turned ON in admin.

You are correct. The readme is over simplified and does not include the code snippets which were merged into the core Zen Cart files provided in the mod package.

Woody,

Sorry for the very late reply to your last assistance to my issues, I was pulled away from this project for several days and unable to look into it further.

I really appreciate the time you invest in assisting others with a contribution that is not even yours. Says a lot about you.

I have resolved my problem, though it took some head scratching. After following your instructions carefully, I still could not get it to work. Turns out that some of the customization done by an earlier development team on the core files was not allowing the replacement of the image tag. Had to do with the rollover image for schematics available on some products. I had to go in and make some modifications to correct this.

All is well again in the land of playground equipment.

Once again, many thanks for your assistance.
