help with search script.

[smity911]

Hi all,

 

I found and changed the following script around a title but i am un able to get it to display file names and would be great full if any one could help me.

 

what i want it to do is instead of looking for the file title and displaying it i am tring to get it to display the file name but it is currently pulling it from <title>HERE</title>.

 

Oh and just wanting to know would it be possible to search the file name to?

 

Thx in advanced.

Abbout:

Some people say php is not the language to do a fulltextsearch and they are

right ;-) but anyway: terraserver.de/cSearch performs a realtime fulltext-search

over spezified directorys including subdirectorys and returns a link and an

extract of each file. Htmlspecialchars are supported so a search for "über"

will return documents having "über" as well as documents having "über".

Depending on the performance of your webserver, with terraserver.de/cSearch you

should be able to search in about 1000 (html-)files.

 

Systemrequirements:

- Testet on Linux/Solaris/Win2000 with Apache 1.3.19 or higher and

  PHP4.04pl1 or higher

 

Changes:

- Added multiple Languages - German, English and French (experimental ;-) -

  depending on client browser's HTTP_ACCEPT_LANGUAGE with possibility to search

  different branches of your server

- Added limitation of results per page

- Added an example html-file to use the search outside php-files

- Strip php- and html-tags from search except of <title></title> tags

- Added advanced view on/off

- Added some more features like 'match case' and the possibility to limit the

  number of results

 

Configure:

Edit config/config.inc.php and the language files in config/languages/ to fit

your needs.

 

Have fun...

I wouldn't recommend even using this script. It is badly programmed and parts are obsolete.

Obsolete

$HTTP_GET_VARS

The use of global variables is a major security risk and poor design.

[npsari]

Wow, that is one huge script you showed here

My prsonal opinion is to create a search script yourself

I created a search script for one of my sites

The reason is, because I wanted to know exactly what the script consists of

Therefore, you can add and subtract in the future as much as you wish

But ofcourse you can get readu scripts from the net if you dont know how to make them or dont have time

Thx for the advise but i was planing on using it on an intranet so security is not the bigest issue.

 

Short of righting it my self is there and scripts that would do similar to this, as we have over 350 forms on our intranet and i need an easy way for users to ether do a mysql search or a script like the one i have shown that will enable users to type part of a file name and show a list of results that can be clicked to download,

i allready have all the files in a sql db.

 

Thx

This is just simple sql. Why do you need a specific script?

SELECT * FROM abc WHERE x LIKE 'myfile%'
