linking to external images, outside of 'images/'

[Alexiss]

Welcome!

I was successful using this method:

http://www.zen-cart.com/wiki/index.php/Contribution:Web_images

I however need to be able to display multiple images on the product page.

Here is the thread that I describe it in:

http://www.zen-cart.com/forum/showth...361#post821361

Hi Dose anyone know how I can do this? I tried to figure this out but I just don't get it. http://www.zen-cart.com/wiki/index.php/Contribution:Web_images can some one explain to me if I am just adding the lines that are in this Contribution anywhere in the file it specefise it gose in. Dose it go in the top or bottm of the file. Where in the file dose it go. Or is it rplacing something in the file or am I just adding the code to the spesified php file. Can some one please explan to me how I can make this work for me to.

Thanks for your time and Help.

I tried this today and can't make it work. When I impl'd it all images disappeared. I immediately restored my backup files and I can get images from my server normally just as before.

I know I've done something wrong, but I can't see what. I agree that for those of us who are not php gurus the implementation of a mod like this will be traumatic. Too many files to change, many changes in each file, no easy way to tell if a line should be replaced or the new lines just added. The implementation instructions could be more clear as to where to make the changes and if a change replaces an existing line or is an addition.

I use Notepad as my editor, so just giving me line numbers as a way to point to the change doesn't always come out right.

I did look at the author's website and it appears that he is able to get images from both his local server and use linked images from another server at the same time, so if he's using the same changes he posted in the wiki I guess we're too dumb to understand.

It's probably impossible to do, but if the author could zip up the live files needing changed from his website and let me look at them to compare to what I did, I'm sure I could make it work .. and also write sensible instructions that anyone could follow.

The best solution tho, would be for the Zen programmers to add this into their next point release and the entire issue would completely go away.

I promise that when I get more familiar with the Zen Programs (and PhP) I'll quit asking noob questions ..

Just a note.

The original wiki article was posted on 4 November 2006. Since it's three years old I wonder if the changes are still valid for the current release of Zen Cart?

I got this to work. Wherever there was a line number referenced I looked to see if there was similar code. If there was, then I replaced it with the code from the contribution. If there wasn't similar code then I inserted it at or near the code line that was referenced. Be sure to include comments and test after each change.

I had to change the length of the database field "products_image". I set mine to 128 characters.

My question now is how do I now get multiple images to display in the product page? For starters, I have created new database fields called "products_image02", "products_image03" etc. Using EP I have uploaded the URL's of the additional images and I can see them in the database fields. I do not know how to call them from the database to display in product page.

Here is the site: http://www.micmed.com/simpsoncycles/

The image names come from another application, so using common basename+ consecutive numbers will not be practical. The images HAVE to served from another location. There are hundreds of items that will be uploaded each week. There are 10 image field URL's that will be uploaded for each item via EP.
The main page images are local. The additional images on the product page are in the HTML, but my client does not want to have to insert them into the HTML product description.

I had an email exchange with the author. They were just experimenting with this about 4 years ago and has since moved away from PHP programming.

That's what I did. I probably didn't do my "inserts" in the same places you did. Most likely that's the problem.

Have you given any thought to sending the files you changed to me so I can look at them and then do a complete writeup of the implementation instructions?

I made mine 256. (I know .. but that's what I wanted)

Not related to this, but I found that the product name field and the product description field were also too short for my use and were being truncated. I increased the size on them too.

Nice looking website! I don't ride, but I do appreciate sports cycles.

From what I see, making external images work with Zen Cart would be a major change. It's just not set up to allow external images.

I'm not a good PhP coder so I'm not the one to even think about it. expect that there are a lot of PhP gurus out there who could do it without much anxiety, tho ..

Thanks for responding. I've decided that if I can't make this "linked Image" thing work I'll upload all 10000+ images to my server and use them the Zen Cart way. The only other choice I have is to find a different shopping cart where 'bandwidth' is not so much of an issue ..

I found another source for micmed's code. What he's posted is apparently not quite complete.

The code at tumblr.com/tagged/remote+images states:

Basically you assign the constant DIR_WS_IMAGES to a variable $imagepath.

Then add the short method to check if the image starts with http.
If it does up then set imagepath to blank. else use DIR_WS_IMAGES.
You must also insert $imagepath in place of DIR_WS_IMAGES in the zen_image function calls.

In addition to these files a number of other files need
to be updated. All products, featured, new, cart, listing, product info and maybe others.

Make sure to pay attention to the file product being referenced
for example:
$featured_product->fields['products_image']
$new_product->fields['products_image']
$listing->fields['products_image']

etc.

The shopping cart also must be updated.

I have installed the micmed(tumblr.com) code (don't really know where it originated) on my test site and have everything working except Categories. When I click on a category, I get no products and no images for that category. I expect I have a few more files to modify.

Clicking on 'Specials', 'New Products', 'Featured Products', and 'All Products' works fine.

So .. I will continue looking and testing. When I have everything working ok, I'll post the results. If anyone would like to add anything to this, please do.

For the record, I just implemented micmed's code from his contribution page on the wiki and it worked perfectly (thanks). There are a few places where it isn't clear what to remove from the original code at first but just comment out anything in the original code that looks mostly the same as the code provided.

It should work fine with EP as long as your image field in your txt file contains the full path to the image (http://www.example.com/image.jpg). You may also need to increase the limit on your db field for products > products_image as mentioned above.

image field in your txt file contains the full path to the image (http://www.example.com/image.jpg).

sorry for the stupid question....but I need to know how to find the path you mention above. I notice there are several "image" folders....in admin, in english, in my STORE's name. Question:

I do a manual upload to froogle (at their site), NOT using any zen cart mod. just want a STATIC unchanging url for each image. What folder should I upload my product images to?

Thank you in advance

[gjh42]

Any image located on your server will have a static URL, as the images are not moving from folder to folder.

Product images should generally go in the base /images/ folder or one of its subfolders.

Hi Glenn~

THANK YOU for caring enough to answer. I'm not sure what you mean by "base". I have created a new folder (and named it LRG), in the images folder located in my store's folder. Is it ok to upload my product images to where I have which is:

store/images/LRG/image01.jpg

Thank you so much...from this to this
