Image Handler 5 (for v1.5.5 - v1.5.8) Support Thread

[lat9]

Hi
This is a general question:
Is there a simple way to get the IH image ?
Asking this, because I doing a autocomplete search box and if possible, it would be best to use already resized images.
I'm following the admin image_handler page, but I guess that's for comparing , etc...

Thanks

Is this for a storefront or admin search box?

In this case Store front

thanks

That one's easy, then! When you call the zen_image() function and have IH loaded and enabled, that function (in turn) calls the IH function to handle that image. Net/net, that's the way to get a resized/cached version of the image.

So I guess the other one it's difficult,... and that's the one I need. I didn't explain myself. The autocomplete is for the store front, but ,(still testing) I'm creating a json file in the admin area, so it's there that I need to get the IH (small) image path.

The admin-side is a bit more complicated, since that version of the zen_image function doesn't look for/use the IH-supplied re-formatting. Which type of Cache File-Naming Convention are you using?

That's a IH5 feature right ? I'm still using IH4, but I intend to move to IH5, but I didn't had the time yet.

Perhaps I shod upgrade first and ask later ... is this stable now ?

The GitHub repository is in a bit of flux, but the released version is stable. Since you're using IH4, you're using the hashed version of the cache file naming.

I'd recently looked this up for a client, so here's the process, assuming that you're using the IH-4/5 default settings.

1. Take the products_image definition from the products table in the database, let's call this $products_image.
2. Prepend that value with the images' directory: $image_source = DIR_WS_IMAGES . $products_image;
3. Append that value with the default settings: $image_source .= ('85' . '255:255:255' . 'Center');
4. Create an md5-hash of that value: $cache_filename = md5($image_source);

That $cache_filename now contains the filename portion associated with the cached image. Images are stored in the /bmz_cache/$cache_filename[0]/$cache_filename.image.$dimensions.$extension, where $dimensions = $width . 'x' . $height (of the image) and $extension is the image-file's base extension.

That description's probably a bit muddy; just post back if you have additional questions.
