General Support: Zip Download

I can't get my zip to work at all... everything else works fine though it's odd. I'm using the Version 3.0 Beta... Is anyone else having the same issue?

Hi Bilel - please can you give me more information as i'm pretty naive when it comes to scripting etc - if you could spell it out to me that'd be great!

Thanks,

Amanda.

Thanks dhdesign for your help - zip is enabled but gives no details of its version. It does, however, list a BZip2 version of 1.0.3, 15-Feb-2005. Also it lists no Libzip version but does give a ZLib support version of 1.2.3. Zlib.output_compression is off, zlib.output_compression_level is -1 and zlib.output_handler has no value.
Is this any help....?

Many thanks,

Amanda.

I discovered the issue is with the native themes that come with plogger3 beta (they didn't allow for pic downloads from the webpage even when downloads is selected in the administrative panel). I tried some of ardamis's themes and plogger compiled selected pics into zip format no problem. Thanks Ardamis


Would really suggest to the admins taking a lot of the FAQ's on here into one section so the problems aren't asked a million times in the forums as I see they are. I'm sure some people on here probably get tired of answering the same old questions but over time people wonder if those answers still apply currently.

Did you try his newest one's? The old ones didn't work for me until I tried the newer beta versions including air beta and broadway beta... nothing else worked

Amanda - have you been successful with a smaller zip download with just a few small images, with a total download size under 2mb? It's possible that your webhost has set resource limits, and the script is exceeding those limits, and times out while trying to create the large zip download.

If that is the case, that isn't a problem with Plogger but with your host. You may have to talk with them about what is happening and see what limitations they have in effect for your server.

Thanks again guys for your help - small images download fine so I upgraded my hosting package to one that gives me shed loads of available memory and space, but still no joy. I'll speak to them again about it (Webfusion), but frankly they are very very unhelpful!

Ta,

Amanda.

Oddly I have found that I can download if I am using Firefox but not if I am using IE. I'm just about to try Adam's theory and install the Beta version of Broadway. Anyone else found this as a browser specific problem?

**update**
The download facility does indeed work in the beta version of Broadway when using IE. I will have a look at the basic template when I get a chance and see if I can spot the difference. However, am out of the office next week.

I've done some digging on the web regarding this too and it doesn't seem to be a problem with Plogger, but happens with the zip download class that Plogger uses (ziplib by Eric Mueller). There are plenty of people out there experiencing the same thing when using the zip class for direct downloading (i.e. creating a zip file that is being output directly for download and not stored physically on the drive). Unfortunately, there also doesn't seem to be anyone that has found a way around it (or necessarily a better one either) besides upping your php memory_limit (sometimes up to 500MB!). There is a php class that I found that looks to work in a different manner that I am going to try messing with, but it may have just the same problems as previous ones.

Also, I haven't been able to duplicate the error on my server (even setting my memory_limit to 2M), but I don't have that many pictures. If I come up with something, I'll let you know. If anyone else comes up with something, let me know too.

Well, I played around with the existing Eric Mueller class a little, but I didn't come up with anything extremely insightful. However, I do have a few test edits that may try to solve some problems. I've uploaded the tests here. I have tested them on my server and they all work (although it worked on my server before anyway, so it doesn't really mean anything :P ). Since I cannot duplicate the error on my server (yet), feel free to try them out (but make sure to make a backup copy of the original plog-download.php file first!). Let me know if anything works (or at least works *better*).

I'll keep looking around too, but the other zip classes I've found don't seem to work well across all OS's (some have separate files for Windows vs. Linux vs. Mac) and none of them are guaranteed to work any better than the Eric Mueller class (they use this for the Zend library for goodness sakes! :p ).

Anyway, good luck and let me know if any of them work! :)

Great amanda!

All #5 does is up your php memory_limit! :) I think you have it set to the max in your php.ini file, but then the plog-globals.php functions neck it back down to 64MB with it's own ini_set function. All I did was up it back to 500MB in the plog-download.php file.

As to anything over 42MB, can you tell me what the error is that you get? I'm wondering if the max_execution_time needs to be upped as well since the larger the file is, the longer the script will run too. If you can narrow down what the error is, I can take a look at altering the ini settings for the plog-download.php script only (the rest of your site and scripts will be what they normally are).

Anyway, glad it's working for you!
