Thumnails not always being displayed.

slowgin

This is my first php site I have put up and find that some thumb images are being dropped. It is a variable feast. Opera drops very few but Firefox drops a lot more. A screen refresh will simply change the thumbs that are dropped.

The site has been designed using Dreamweaver and spry tabbedpannels with the images stored in the database. (Yes I am aware of the active debate as to whether this is a good idea)

Is this a php problem? Suggestions at solutions and critique on the design greatly appreciated.

Cheers
Rob

If it is, shouldn't you be asking PHP and not us? :p

Do you have error_reporting set to E_ALL and are you logging all PHP errors?

I'm sorry if this is the wrong place for the question but the forum is titled "General Help Forum for General Help questions pertaining to PHP" so seemed a good place to ask.

Yes I do have error_reporting set to E_ALL - NO errors.

I was implying that if PHP was having trouble loading the data or something of that nature, then it would be generating error messages and you should be able to tell us that PHP is to blame, not the other way around.

Okay, but since the images are loaded via PHP scripts, then you wouldn't be able to see the errors related to those scripts even if you had display_errors on (unless you tried to load those scripts directly rather than the main page).

That's why I asked if you had error logging enabled. If you still claim that you have 'NO errors', then why does this URL result in the popular 500 error page:

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

? :p

mmm feel as if I am getting out of my depth here.

Testing the site on my PC using XAMPP installed Apache and PHP was fine. Error reporting turned on and log file clear. But I was not having any difficulty with thumbs being dropped.

Since uploading I have noticed the problem.

The online site has error reporting off and No Error Logfile. I checked with phpinfo() .I have now turned on error reporting by adding error_reporting(E_ALL) to the index page and uploading it but not sure if I can or how to turn on the error log.

I tested out the link in your post and could not get any error message to occur.
I'm confused as to why you should get an error message and I can not reproduce it.

Okay, but that only affects the index page and not any other PHP script (e.g. the rotate.php script) on your site.

You can use [man]ini_set/man to enable error logging in a specific PHP script, but it's better to do this in a site-wide manner. To do that, you'd have to know how your host has setup PHP on their servers. You should either be able to supply your own php.ini file at a certain location to be parsed, or you might be able to modify PHP directives in a .htaccess Apache configuration file.

It worked for me now as well, and not every page load was showing a broken image for me earlier as well. This could quite easily point to a limited-resource error, but again we'd need to see the PHP error messages to know which resource to examine.

Is this true even when rotate.php is an include file in the index page?

As for modifying the php.ini file I'll have a word with my host's help line and see what I can do.

Thanks for your input. Most helpful

For included files? No. But you aren't [man]include/man'ing rotate.php in your index page, so that's not relevant.
