How to: set a new window on every click and send database links instead of true links
Hi,

I would like to ask about two modifications.

First question: how to set the program to open a new window on every clicked link (like target=_blank)?

Second: (How) Is it possible to modify the email newsletter - I would like it to include database links instead of true links? I mean: I would see there:

http://mysite.com/links/user-cgi/jump.cgi?ID=1000
and not: http://true.link.com

The answer to your first question is easy -- just place the target tag in the link href in the link.html template. If you are using the random link, you will also need to add the target wherever it shows up in your other templates.

I don't know the answer to your second question, but it was just discussed in this forum within the past couple of days. Shouldn't be too hard to find and see if any solution was reached.

Hello,

I wrote a mod to use the database link instead of the actual link. It's in the resource center at this url http://www.gossamer-threads.com/...ces/jump.cgi?ID=1096

If you are asking me, I just grepped throug the links file to find the code that generates the newsletter links. I then wrote up the mod and posted it in the resource center.

Re: How to: set a new window on every click and send database links instead of true links In reply to
But one of the two modifications must be wrong - I think, it's db_utils.pl.

I've changed all very carefull and tryied three or four times: I cannot open the newsletter page from the admin panel now: error 500.

The new links.cfg is OK, it did not stop the script, but the modified db_utils does :-(

Re: How to: set a new window on every click and send database links instead of true links In reply to
Hello,

I did not need your whole db_utils.pl, just the parts that pertained to this mod Wink

I don't seen anything in this that would be causing the 500 server error. I did notice something that is wrong with the way the mod was applied. Here is your code:

Code:

$output .= qq~
-------------------------------------------------------------------
$rec{'Title'} (added: $rec{'Date'})
$rec{'URL'}
$des_q
~;

It should be:

Code:

$output .= qq~
-------------------------------------------------------------------
$rec{'Title'} (added: $rec{'Date'})
$url
$des_q
~;

The difference is that your code has $rec{'URL'} which will always give you the url for the resource. The variable $url is set in the mod to contain either the direct url or the url through jump.cgi.

Do you have access to your web server error logs? They usually contain the details of the error which should point you to the error or the line number of the error.

Hi again,

I've tryied with $url - the same error 500. It must be somewhere else. I don't have direct access to the error logs, but I've just asked my administrator and I hope, we'll know the reason soon :-)

Thanks God, I have still the both old files links.cfg and db_utils.pl ;-)

That's why step #1 of the mod says to backup up your links.cfg and db_utils.pl Wink

I'll keep an eye on this thread to see if you can get access to your error logs.

Re: How to: set a new window on every click and send database links instead of true links In reply to
Hi Frank,

I have the results of two tests. The first one was perl -d for the newsletter command:

[1] 9229
perl: No match.
html_mail_update=1: Command not found.
[1] + Exit 1 perl -d /path/to/my/cgi-bin/links/admin/admin.cgi?db=links

And this is the error log:

[Wed Mar 29 23:30:42 2000] [error] [client 195.232.72.50] Premature end of scrip
t headers: /path/to/my/cgi-bin/links/admin/admin.cgi

Does it make something clear?
