Understand and Enable Search Engine Friendly (SEF) in Joomla

Search Engine Friendly(SEF) also known as human readable URL. With the most famous Web Service like Nginx, Apache and IIS7, they do support URL rewrite or mod_rewrite to rewrite the human readable URL such as www.domain.com/about instead of www.domain.com/about.html.

With Joomla 1.5 and above, Joomla come with 3 option from your Global Configuration.
–  Search Engine Friendly URLs – With this option enabled, SEF will enable and your URL will look like, http://www.example.com/index.php/the-­news/1-­latest­-news/1­-welcome­-to­-joomla.
– Use Apache mod_rewrite/URL rewriting – With this option enabled, mod_rewrite will eliminate inde.php and your URL will look like, http://www.example.com/the-­news/1­-latest-­news/1-­welcome-­to­-joomla
– Add suffix to URLs – With this option enabled, your URL will added .html at the end of the URL and it will look like http://www.example.com/the-­news/1­-latest-­news/1-­welcome-­to­-joomla.html

Nginx
To enable SEF with Nginx, add the following line to your (vhost)nginx.conf file.

# Support Clean (aka Search Engine Friendly) URLs</tt>
        location / {
                try_files $uri $uri/ /index.php?q=$request_uri;
        }

Apache
To enable SEF with Apache server, you may easily rename the htaccess.txt to .htaccess file. This step is not necessary as you may get your .htaccess file generated if it is install in  own folder.

IIS 7
With IIS 7, you may choose to use GUI or directly add it from web.config file.

With GUI interface, you may add the following option from the URL rewrite option.

Pattern field: ^([^/]+)/?$
Ignore case ON
Action type: Rewrite
Rewrite URL: index.php/

 Otherwise, you may add the following line to your web.config file.

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
        <rewrite>
            <rules>

Joomla: migrate content from Joomla 1.5 to Joomla 1.7

This article is sharing how to migrate your Joomla 1.5 content to Joomla 1.7.

As Joomla 1.5 and Joomla 1.7 come with different structure, you might found out it is difficult to upgrade your Joomla directly from application source. However, you may upgrade the content from back-end.

First of all, you need to ensure the database prefix and assume that you are using original prefix named jos_.

To backup from Joomla 1.5,
1. Log into the PHPMyAdmin.
2. Select on SQL tab.
3. Enter this query,

SELECT `title`, `alias`, `title_alias`, `introtext`, `fulltext`, `state`, `sectionid`, `mask`, `catid`, `created`, `created_by`, `created_by_alias`, `modified`, `modified_by`, `checked_out`, `checked_out_time`, `publish_up`, `publish_down`, `images`, `urls`, `attribs`, `version`, `parentid`, `ordering`, `metakey`, `metadesc`, `access`, `hits`, `metadata` FROM jos_content

4. Select on Export from bottom.
5. Click Go to save it.

To restore to Joomla 1.7,
1. Log into the PHPMyAdmin.
2. Click on the Import button.
3. Select the file and import it.
