Image Handler 3 Support Thread (for ZC v1.3.9)

[thebigkick]

Trying to disable the Image Handler v3 Hover effect for certain pages. I like how it is functional on the product page, however, I don't like the effect on the Home page under the Review and Featured Items is displayed.

Thanks

I'm afraid this is an all or none feature.. If I recall correctly it would require a fair bit of coding work to disable it selectively as you would like.. Perhaps others can offer more insight on this..

So people will stop asking about Clydes "fix" for IH3 with Zen Cart v1.5. As I suspected getting IH3 to show up in the admin is only HALF the battle.. IH3 needs a RE-WRITE to work with v1.5..

But converting addons for v1.5 compatibility requires two primary things:
a) rebuilding the menu options by inserting the required page associations into the database.
b) rewriting all forms to use the POST method instead of GET whenever those forms trigger UPDATE statements of any sort into the database. GET parameters should only be used for things like filters, and even then they need to be sanitized. In fact, the other part of form rewriting is that ALL inputs need to be sanitized before use.

If you don't do those things then your admin won't show the menu options, and even if they did they might be non-functional because if the forms aren't rewritten and sanitized then all updates will just redirect you to the admin home screen instead of doing the action required/expected..

I KNEW I was right about this when I made the statement earlier in this thread..

The addon needs to be upgraded to work with the new admin menu system in v1.5. There are several discussion threads which address those matters.
There are several more things, security-related, that are also required when upgrading modules for compatibility with v1.5. If you don't also do those things then your addons will not work either. They'll be redirecting you to your admin home page every time you click on a link in the addon.
So, merely adding menu options isn't sufficient for all addons.

Can you help me?

OK. I find solution myself. For sake of those who have those errors, try this solution.

**this solution needs Cron setup**

*************
Error n1.:

charset `windows-1250' not supported, assuming iso-8859-1 in .../bmz_image_handler.class.php on line 690

This kind of error i can repair. It is because of filename. Is in my language and i can not find a solution (i try many solutions -FAIL), only delete error log.


cron setup -> time- * * * * * ,, cron script put in directory"../cron/"

create a file cron1.php (and copy code)

<?php
if ('deletespecificfiles.php' == basename($_SERVER['SCRIPT_FILENAME'])) {
     die ('<h2>Direct File Access Prohibited</h2>');
}
else {
$foldertodelete  = '  --your path to--/web/cache/  ';
//DELETE Log FILES
$fileTypes1      = '*.log';
$expire_time1    = 3;
foreach (glob($foldertodelete . $fileTypes1) as $Filename1) {
$FileCreationTime1 = filectime($Filename1);
$FileAge1 = time() - $FileCreationTime1;
if ($FileAge1 > ($expire_time1 * 60)){
unlink($Filename1);
}
}
}
?>

when cron start - in every 1minute - he delete only log files in /cache

*************
Error n2.:
BIG //bmz_cache//.

cron setup -> time- 0 12 * * 7 ,, cron script put in directory"../cron/"

I setup cron to start every Sunday midnight (because, bmz_cache needs to be filled /for some time/ because if bmz_cache is clear, image handler must create new cache - that slows server (tested on localhost and live shop).

create a file cron2.php (and copy code)

How many files is "too many files"?
What error are you receiving?
or is it a hosting restriction?

[niccol]

Huh? I thought the point of Image Handler was that it cached the files. If you delete them then what is the point of having Image handler? If the store has any level of traffic whatsoever the cached images are just going to be re-created pretty much straight away and you just slow down the page load for some customers.

A much better solution would be to have a server that has enough disk space to store all the images that are needed for your store.

Nods in agreement..

I agree with niccol.. Your solution is NOT recommended for ANYONE.. The point of the cache folders is to help improve site performance. (A HUGE reason to use Image Handler) Your solution trashes this feature and in fact will probably slow performance down..

My "better solution" (since you asked)?? As niccol points out, host your site on a server that will not put restrictions on your site that will prevent you from using Image Handler. Chances are these restrictions will eventually limit your ability to run any kind of decent website anyway..

[Athens Collectibles]

Hold on Querk, I think there's a confusion between bmz_cache and cache here. This charset problem produces thousands of log files in the cache folder. On the other hand, the bmz_cache folder holds cached images which are required and will be generated again when you delete them.

I had the same problem with thousands (not just too many) files created in the cache folder every day. If you go back a few pages to post #676, you will see how I solved it based on a previous suggestion by niccol. No cron jobs or anything else: just a one-line change in a file. Read the post, see if this is really the issue and leave the bmz_cache alone.
