General Support: Error when uploading zip: Cannot modify header information - headers already sent by

Dear All,

I get the following error message when uploading a zip file through the upload tab. It shows when the zip is uploaded (successfully). I have integrated Plogger into the website and all other features work fine. See here <a href="http://cakeseleven.com.au/photogallery/index.php">

<code>Notice: Only variables should be assigned by reference in /homepages/24/d336574027/htdocs/photogallery/plog-includes/lib/pclzip-2-4/pclzip.lib.php on line 233

Warning: Cannot modify header information - headers already sent by (output started at /homepages/24/d336574027/htdocs/photogallery/plog-includes/lib/pclzip-2-4/pclzip.lib.php:233) in /homepages/24/d336574027/htdocs/photogallery/plog-admin/plog-upload.php on line 88</code>


I would be verty grateful for any comment on this. There are only 3 similar problems described in the forums but no answer.

Thanks for the fast reply. I had a check and did upload the original file and the error still exists. It is following document (that comes with the installation files: galleryfolder/plog-includes/lib/pclzip-2-4/pclzip.lib.php and line 233 is: $v_arg_list = &func_get_args();

I can't paste the script, but it is the actual version ..

I hope that helps ..

Thanks so far ;)

Hello Tojsha ,

As I see it, Plogger makes a semantic distinction between "integration" and "embedding".

The Plogger docs tout integrating plogger with 3 lines of php code - and warns about the whitespace problem and the "headers already sent" errors that can occur when gallery.php is included. This kind of integration, while simple, is only a technique to "drop-in" a Plogger gallery to a specific page.

Unfortunately Plogger is endowed with a mindset that the world revolves around a photo gallery and it is in control of that world. That view often clashes with the design and purpose of the website and its supporting pages.

In other words, this integration is usually not "seamless", and if you want the functionality of your site to be that way then you have to "embed" Plogger into submission with php.

Embedding requires significant changes to the _install.php, the plog-config.php, and to most of the php pages in the plog-admin directory. Worse, it promises a nightmare update when a new version of Plogger is released. But the good news is that it brings the wealth of Plogger functionality into your website without changing its design or presentation essences.

So getting back to the "headers already sent" issue, I think this forum would be overflowing with complaints about uploading a zip file if it was a Plogger malfunction. Since it is not, then it seems logical that the problem lies in the way you either "integrated" or "embedded" Plogger into your website.

Since there are so many coding variations involved I can only offer a couple of suggestions. First, save Plogger some trouble and set the 'PLOGGER_EMBEDDED' definition in plog-config.php to true (1). Second, you might consider enclosing your integration code in an output buffering envelope with ob_start and ob_end_flush. And finally perhaps setting the 'PLOGGER_DEBUG' definition to 1 in plog-config.php may provide you a better insight into the problem.

Thank you for your time! I will have a try if i can solve it myself. The thing i don't understand is: "Second, you might consider enclosing your integration code in an output buffering envelope with ob_start and ob_end_flush" .. Could you provide me with the code as i cannot program php? I really appreciate your time! Thanks.
