PHP - Offset Results Returned From Opendir/readdir

Hi folks,

First time posting here and a bit of a novice at PHP, but am learning....

I am fiddling with a small bit of code to create a very basic php gallery (I'm sure everyone has at some point). I started off with a mysql intergrated one then thought I would try a new one without the mysql.

Its working fine but I am just having one very strange problem.

Basically, I started of with just /mygallery/index.php?w=... where ... = the location (physical folder) of photos. I use opendir to open the contents of w= and parse whether it is a directory or a file (then narrow it down to just images).

If it is a dir, then I present it as a link to that folder (sub-album) if it is a photo, I present a thumb link to the image.

Now I have added a mod_rewrite rule to allow my urls to be of the form 'mygallery/album/subalbum'   this gets ocnverted into 'mygallery/index.php?w=album/subalbum'

Now the funny bit. If I create a new folder in one of the subalbum, e.g. : mygallery/album/subalbum/<b>New Folder</b> the code works. i.e. when I point my browser at 'mygallery/album/subalbum' I get a link showing 'New Folder'

But if I create a new folder of any other NAME it does not appear in the list!! So if I just rename 'New Folder' to 'New Folde' it drops of the web page!!!

Now I am really not sure what the hell is going on...

Hope someone can help.

I will post my code if necessary.

Thanks in advance!

Hi guys,

I am working with an old script at the moment, there is one page which just will not populate the table results.
I have tried running multiple debugging commands but the only one it flags is the line displaying Quote

last;

saying it's not a used function.
If I comment out this line, no errors are produced but the results do not enter the table.
Can anyone shed some light on this please, I've spent hours and hours and banging my head against a brick wall would probably be more constructive right now.

Many thanks indeed for any help or advice.

Greetings!

This n00b has a "search engine" dedicated to extracting relevant information from log files. It works by parsing preset fields in the log filename.

I'd like to have some notification when the search returns no rows as I am planning to add more search options. Here's my code:

When doResult_PFN() returns no result, the ELSE portion is never evaluated and no notification is sent to the user. However, I have no problem with doScriptVersion(): it returns an alert.

What am I missing?

Thanks,

Hello.  I am interested in taking a result returned from a database and having it displayed in a certain way/style on the user's screen; For example, the user enters text into a field and hits "submit" - the data is saved in the database then displayed to the user (This part I have working just fine so far due to help I received here.)

My question is if I would like to, for example, have said text not simply dumped to the top of the screen, inline, but nicely formatted in a boxed, text area, I assume I will use HTML/CSS, and I was wondering if anyone had any good links/tutorials regarding this topic so I may look further into it (my search thus far has not turned up the correct topic or results).

Thank-you in advance for any assistance.
