How do you connect Joomla with an MySQL database?

Let me share code below-

$option = array();
$option[‘driver’] = ‘sqlsrv’;
$option[‘host’] = ‘server’;
$option[‘user’] = ‘user’;
$option[‘password’] = ‘pass’;
$option[‘database’] = ‘db’;
$option[‘prefix’] = ”;
$db = &JDatabase::getInstance($option);
$query = $db->getQuery(true);
$query = “SELECT * from Test”;
$db->setQuery($query);
$results = $db->loadObjectList();

Joomla Database Connection variables

First of all $option is an array variable that contains 6 array variables.

  • Driver: it’s using the database driver type like MySQL (mssql) or SQL server(sqlsrv).
  • Host: it’s using the hostname of the server (localhost)
  • User: it’s using the username of the database.
  • Password: it’s using the password of the database.
  • Database: it’s using the “db” as values for this variable.
  • Prefix: it’s the database table prefix, so what prefix will use with the database table name will be used here.

$db = &JDatabase::getInstance($option);

The above code creates a connection to Joomla with SQL Server. If everything is correct then it will return true otherwise false to the $db variable.

You can check what value is coming in the “$db” value by using following statement of code:

If($db== true){

$query = $db->getQuery(true);

$query = “SELECT * from Test”;

$db->setQuery($query);

$results = $db->loadObjectList();

}else{

echo “Database connection failed!”;

die();

}

So if the $db variable returns the true then you can write database queries like SELECT, UPDATE and DELETE.

In the above code, I have written a SELECT query to fetch data from the “Test “ database table.
