mysqli support

I tried to install and run ltwCalendar on PHP5 with mySQL version 4.1.7 and it doesn't work. With newer versions of mySQL, you need to use the mysqli functions in php rather than mysql. I have an updated version of ltw_classes.php available at:

http://www.bryangraham.com/ltw_classes.zip

the PHP code just for the class ltwDb is as follows:

php Code:

Original - php Code

/////////////////////////////////////////////////////////////////////////////

// class: ltwDb - common DB interface

// Currently, only MySql (type = 1) is supported.

// Adding other DB's should be a matter of adding cases to the

// "switch" statement for each function.

/////////////////////////////////////////////////////////////////////////////

class ltwDb{

var $db_type 		= '';

var $db_server 		= '';

var $db_name 		= '';

var $db_user 		= '';

var $db_pass 		= '';

var $db_persistent	= '';

var $dbh 		= '';

// constructor

function ltwDb(){

global $ltw_config;

$this->db_type 		= $ltw_config['db_type'];

$this->db_server	= $ltw_config['db_server'];

$this->db_name 		= $ltw_config['db_name'];

$this->db_user 		= $ltw_config['db_user'];

$this->db_pass 		= $ltw_config['db_pass'];

$this->db_persistent	= $ltw_config['db_persistent'];

$this->db_connect();

}// end constructor

function db_connect(){

switch($this->db_type){

case 1: //mysql

if ( $this->db_persistent ){

$this->dbh = @mysql_pconnect($this->db_server, $this->db_user, $this->db_pass);

}else{

$this->dbh = @mysql_connect($this->db_server, $this->db_user, $this->db_pass);

}

if ( !$this->dbh ){

echo "Error: Connection to MySQL server ".$this->db_server." failed. n";

return;

}

if ( !@mysql_select_db($this->db_name, $this->dbh) ){

echo "

------ Message:".@mysql_error($this->dbh)."

die ("Error: Fatal db Error. n");

}//end mySQL

break;

}//end switch

}// end function.db_connect()

function db_query($query = ''){

switch( $this->db_type ){

case 1: //mySql

$result = mysql_query($query, $this->dbh);

if ( !$result ){

echo "

Error: A problem was encountered while executing this query.

$query <HR>$query

die ("Error: Fatal db Error. n");

}

break;

}// end switch

return $result;

}// end function.db_query()

function db_numrows($result){

switch( $this->db_type ){

return mysql_num_rows($result);

RE: mysqli support

I noticed I'm a complete idiot and I posted the code from the unmodified version of ltw_classes. Here is the updated code - it makes use of the db_type variable from the config file, set it to two to use mysqli instead of mysql.

php Code:

Original - php Code

$this->db_user 		= $ltw_config['db_user'];

$this->db_pass 		= $ltw_config['db_pass'];

$this->db_persistent	= $ltw_config['db_persistent'];

$this->db_connect();

}// end constructor

function db_connect(){

switch($this->db_type){

case 1: //mysql

if ( $this->db_persistent ){

$this->dbh = @mysql_pconnect($this->db_server, $this->db_user, $this->db_pass);
