Hi!

I've been digging around on old posts regarding this but still haven't found a reasonable solution:

I got a URL field in the DB pointing to images on the Web.

I'd like to showcase x random, different images, every time someone enters the site. The URL linking to the image would be the detailed URL.

Any way to achieve that easily? I do have access to SSI, but would like to skip using them if possible.

Thanks!

Its reasonably easy. Just get a copy of the mod at http://cgi-resource.co.uk/pages/randlinks.shtml and edit the line saying;

to

Then, edit;

to

Then open up site_html_templates.pl and create a new sub with the following code;

Then you need to make a new template called link2.html. Put in the code to make an image get shown. Something like;

Then upload that into the templates folder, the site_html_templates.pl file into the admin folder, and the randlinks.cgi file into the /cgi-bin/ (along with add.cgi etc).

Then you can just call the script in SSI enabled pages with an exec cgi command.

Well, hope that helps, and thats to Glen for the great mod in the first place

Hey!

Thanks, I'll try this out inmediately!

What if i want to display extra info, like site's name or category?

Shall I just add it to link2.html or do I need to pass anything else?

Thanks!

I also asume u made a typo when saying:

"Then open up site_html_templates.pl and create a new sub with the following code;

sub site_html_link {"

u meant:

"Then open up site_html_templates.pl and create a new sub with the following code;


sub site_html_link2 {"


right??

Tu!

Damnit!

I'm getting the same error with randlinks.cgi than with recent password.cgi script I complained about some posts ago!

I compared the first lines of randlinks and password .cgis with other CGIs that do work, like add.cgi or modify.cgi, and they're IDENTICAL!!!

I don't get why randlinks.cgi refuses to work!!

This is what i get when called from command line (from Web i get a 500 Server error). File was upped in ascii, chmoded 755, etc.

IDeas???

Thanks!!

Yup, sorry about that . You are right, it should be

sub site_html_link2

Sorry, I don't have a copy of randlinks.cgi with me. Could you post the script here so I can have a look? It may just be that you need to use the full path in thje reuire statement (*instead of /admin/db.pl, or whatever it is).

I'm at work at the mo, but I'll be back in about 30 mins. I'll try to help you out a bit better then

Ok, in randlinks.cgi try changing the following;

to

That will hopefully sort out the problem

What do u thinK?

Can any1 help with this plz? Still stuck!

Try it for yourself:

http://webcamworld.com/directory/


You'll notice add.cgi, modify.cgi, rate.cgi... work fine but things like password.cgi (retrieve password rqred when modifying) or randlinks.cgi do not work.

The fun part is that all of them reside on the same place and contain the same set of instructions:

#!/usr/bin/perl

and

require "admin/links.cfg"; # Change this to full path to links.cfg if you have problems.
require "$db_lib_path/db_utils.pl";
require "$db_lib_path/links.def";
$build_use_templates ?
require "$db_lib_path/site_html_templates.pl" :
require "$db_lib_path/site_html.pl";


Ideas???

When I run password.cgi, it gave me the following info;

Do you normally get that? As for randlinks.cgi, well, try the full path to require "admin/links.cfg";

Oh well!

This is AMAZING!

I've been out of town for holidays a few days, so I've not touched ANYTHING on the server nor scripts.

And now password.cgi is working fine again?!?!?!?!?!?!?!

I don't get it!!!


I'll make some tests with randlinks.cgi now and let you know.


Thanks for checking in!

It could be something to do with your ISP / Servers caching. I have that problem loads of times...it gets really annoying, especially when you are trying to write and debug a script

Ok, now it's happening what I thought...

password.cgi runs fine /still dunno how nor why/

but randlinks.cgi does not.

File was upped in ASCII mode, permissions are ok, tested with full and non-full path, contents are identical to the rest of scripts (password.cgi, add.cgi, etc...):

require "admin/links.cfg"; # Change this to full path to links.cfg if you have problems.

IDEAS????

Thanks!

Double check this path

/usr/local/etc/httpd/webcamworld.com/cgi/directory/admin/db_utils.pl

It doesn't look right.

Hi!

Why do u think that?

Which is the problem u think there is with that path?

Why do the rest of scripts work fine with THE SAME path, permissions and settings?

Thnks!

Paul, youradds,

I've made further investigation on the issue and I've determined Telnet sessions don't help too much...

I tried to ran on telnet a %perl password.cgi and the problem related to paths appeared. HOWEVER the script runs fine via web browser!

In fact, it happens with ALL OF THE CGIs!! ie. telnet does not like the perl scripts to be run remotelly, but the scripts do work fine!!

So, if you test http://cgi.webcamworld.com/directory/randlinks.cgi, the results are 0, Empty, Nothing! So...

I wonder if the mod you suggested to randlinks.cgi before has been tested or are we getting all mad! ;)

I also would like to know if the mod shown above will alow me to publish title and url in addition to the pic.


Thanks!!

In fact, i've just installed the randlinks.cgi (the original one) and a nasty 500 Server error appears. As usual, files were uped in AScii, permissions are ok, etc...

I'm getting mad on this!!

Check your _error log_

Mods:http://wiredon.net/gt/download.shtml
Installations:http://wiredon.net/gt/

Nothing is recorded in there.

Anything else?

 
I still need assistance with this, plz!

Thanks!

Well after some further testing and still don't know how, it began working fine!

Now I wonder: will the fact of calling randlinks.cgi, which actually retrieves 5 random links from the database EACH TIME a user enters the home page, overload a server? How fast will it?

Ideas? Does it proceed?

Thanks!

If your site is running on a reasonable server you should have no real problems. I'm not really sure on the CPU etc consumption of it, but I reallyt wouldn't think it would be that much!
