Re: Image Resizing Script required - a better one...
Another little side note. At the moment we have one image for the primary photo in /images/productphotos/small.
This script will create four new ones for each primary image. My concern is that there will be forever-more, that small file that doesn't have the _ext on it.
It's not vital, but it would be good if on-the-fly, the resize script could delete anything in /small that is the same filename as in /image/productphotos for that file.

Re: Image Resizing Script required - a better one...
Now trying the resize on the fly on our live server, but got an error:
I think it is because we have [ where we need (. But even if I do that with array(, it still fails.
When I tried it, it also didn't like $srcset = []; I Tryed $srcset = array();, but it didn't like that either.
UPDATE...
In the error now it is looking in /images/pages.

My goodness I am seeing some errors now.
Here's one:

Re: Image Resizing Script required - a better one...
Looks like there are a few things going on, then. You definitely need to use array(...) rather than [...] since it's PHP 5.3. Your require statements should probably use absolute paths, using a combination of dirname() and __DIR__ before the file name. That's a fair bit to catch up on this morning and it appears you have already resolved a number of issues yourself, so try making the changes mentioned above and let me know where things are at.
Re: Image Resizing Script required - a better one...
Pretty standard file not found error. Check that the path is correct, check that the bit after /images/ matches the structure of the image type you're using (ie. that it should be pages and not, say, stockbanners). If that's fine, check that the image itself exists, remembering that Linux file systems are case sensitive. With some older iterations of this script saving to the database before moving the file, it's possible that an entry exists in the database but its corresponding image doesn't actually exist. In any event it's worth making sure that you call file_exists before trying to open an image with Imagine. Alternately, ensure you have a try/catch block in place for when these exceptions are thrown.simonmlewis wrote:In the error now it is looking in /images/pages.

Re: Image Resizing Script required - a better one...
This is all correct. The default is images/pages, but thumbnails is product photos and small.
It seems that since we added this additional folder structure element, things have gone a little haywire.
But I don't see a fault in it.

Re: Image Resizing Script required - a better one...
ps it's not thru missing images, because this is happening on all category pages on the demo server. It gets to the first image and crashes on screen with no errors. It's all in the logs.

Re: Image Resizing Script required - a better one...
That function looks fine to me. Try calling the function by itself (even in a separate test script if you like) and see what you get back. The problem may lie elsewhere.
Re: Image Resizing Script required - a better one...
Interesting. Works fine locally, though? Are you able to upload new images on the demo server? What are the error messages you're seeing? Trying to ascertain what all is going wrong and where.simonmlewis wrote:ps it's not thru missing images, because this is happening on all category pages on the demo server.

This does look to be on your local, given the C:\. The undefined variable is probably a good place to start. Let's take a look at functionConsumerResize.php and see what's what.simonmlewis wrote:I'm not getting errors on my local version, which I suppose is good as we have somewhere to go:

I would expect relative file locations to be the same, so I see no reason it shouldn't work on both. Is require_once throwing an error here?simonmlewis wrote:the Categ.inc file has this:

Seems to suggest getPaths is not working correctly as it's returning pages instead of productphotos. Let's check that also.simonmlewis wrote:Also:Why is it looking in \images\pages ???Code: Select all

Re: Image Resizing Script required - a better one...
Ok. How do I check that it's pulling it through?
Also, I see: $imagine = new Imagine\Gd\Imagine(); is in resizeImage, but not in getSrcSet.
Does it need to be there?
Should the top of the functions file be:
require_once (dirname(__DIR__). '/vendor/autoload.php');
$imagine = new Imagine\Gd\Imagine();

Re: Image Resizing Script required - a better one...
The nice thing about having things split out into functions is that you can test them in isolation. One day we can get to unit testing, but for now you can create a test.php file, define the variables you need, call the function you want, and dump the results.simonmlewis wrote:Ok. How do I check that it's pulling it through?
Strictly speaking, getSrcSet doesn't resize anything, so it doesn't need imagine. The on-the-fly resizing is delegated to resizeSingleImage which, as you can see, does instantiate Imagine.simonmlewis wrote:Also, I see: $imagine = new Imagine\Gd\Imagine(); is in resizeImage, but not in getSrcSet.
Not for now. If we were to make a class out of this functions file, then maybe having Imagine as a class property would make sense, but we're not there yet.simonmlewis wrote:Should the top of the functions file be:

Re: Image Resizing Script required - a better one...
Looks that way. Remember that __DIR__ is the directory of the current file and each dirname() goes up one directory.
