I was hoping someone could help me out. I'm building a CRM application and need help modifying the .htaccess file to clean up the URLs. I've read every post regarding .htaccess and mod_rewrite and I've even tried using http://www.generateit.net/mod-rewrite/ to obtain the results with no success. Here is what I am attempting to do.

• Let's call the base URL www.domain.com
• We are using php with a mysql back-end and some jQuery and javascript
• In that "root" folder is my .htaccess file. I'm not sure if I need a .htaccess file in each subdirectory or if one in the root is enough.
• We have several actual directories of files including "crm", "sales", "finance", etc.
• First off we want to strip off all the ".php" extensions which I am able to do myself thanks to these posts. However, the querying of the company and contact IDs are where I am stuck.
• Right now if I load www.domain.com/crm/companies.php it displays all the companies in a list.
• If I click on one of the companies it uses javascript to call a "goto_company(x)" jQuery script that writes a form and submit that form based on the ID (x) of the company. This works fine and keeps the links clean as all the end user sees is www.domain.com/crm/company.php. However you can't navigate directly to a company.
• So we added a few lines in PHP to see if the POST is null and try a GET instead allowing us to do www.domain.com/crm/company.php?companyID=40 which displays company #40 out of the database.
• I need to rewrite this link, and all other associated links to www.domain.com/crm/company/40
• I've tried everything and nothing seems to work. Keep in mind that I need to do this for "contacts" and also on the sales portion of the app will need to do something for "deals".

To summarize here's what I am looking to do:

1. Change www.domain.com/crm/dash.php to www.domain.com/crm/dash
2. Change www.domain.com/crm/company.php?companyID=40 to www.domain.com/crm/company/40
3. Change www.domain.com/crm/contact.php?contactID=27 to www.domain.com/crm/contact/27
4. Change www.domain.com/sales/dash.php to www.domain.com/sales/dash
5. Change www.domain.com/sales/deal.php?dealID=6 to www.domain.com/sales/deal/6

(40, 27, and 6 are just arbitrary numbers as examples)

Just for reference, when I used the generateit.net/mod-rewrite site using www.domain.com/crm/company.php?companyID=40 as an example, here is what it told me to put in my .htaccess file:

Options +FollowSymLinks
RewriteEngine On
RewriteRule ^crm/company/([^/]*)$ /crm/company.php?companyID=$1 [L]

Needless to say that didn't work.
