Getting mysqli escape string to work

[viveleroi0]

I have been working from a modified database_api from the Mantis bug tracking development, trying to get Mantis to work with php 5 and Mysql 4.1.7.

I have downloaded a CVS version of this doc, but there is an error with the mysqli_escape_string.

Here is the total doc:

http://cvs.sourceforge.net/viewcvs.py/mantisbt/mantisbt/core/database_api.php?rev=1.36&view=markup

	$t_core_dir = dirname( __FILE__ ).DIRECTORY_SEPARATOR;

require_once( $t_core_dir . 'adodb/adodb.inc.php' );

$g_db = $db = ADONewConnection($g_db_type);

# An array in which all executed queries are stored.  This is used for profiling
$g_queries_array = array();

# Stores whether a database connection was succesfully opened.
$g_db_connected = false;

# --------------------
# Make a connection to the database
function db_connect( $p_hostname, $p_username, $p_password, $p_database_name ) {
	global $g_db_connected, $g_db;

	$t_result = $g_db->Connect($p_hostname, $p_username, $p_password, $p_database_name );

	if ( !$t_result ) {
		db_error();
		trigger_error( ERROR_DB_CONNECT_FAILED, ERROR );
		return false;
	}

	$g_db_connected = true;

	return true;
}

Then at the end of the doc:

	function db_prepare_string( $p_string ) {
		$t_db_type = config_get( 'db_type' );

	switch( $t_db_type ) {
		case 'mssql':
		case 'odbc_mssql':
			return addslashes( $p_string );

		case 'mysql':
			return mysql_escape_string( $p_string );

		case 'mysqli':
			return mysqli_escape_string( $p_string );

		case 'postgres':
		case 'postgres64':
		case 'postgres7':
		case 'pgsql':
			return pg_escape_string( $p_string );

		default:
			error_parameters( 'db_type', $t_db_type );
			trigger_error( ERROR_CONFIG_OPT_INVALID, ERROR );
	}
}

But I get warnings for that saying "mysqli expects two parameters, 1 given"

Then I tried:

mysqli_escape_string($g_db, $p_string);

That gave an error message "mysqli expects parameters 1 to be mysqli, object given"

Then I tried:

mysqli_escape_string($g_db->$p_string);

And that didn't work.

Any ideas? I have upgraded to latest version of ADOdb which mantis uses. I have php 5.0.2 and MySQL 4.1.7.
