php - Call to a member function query() on a non-object Error how to fix? -


i try every thing not working, please 1 check code?

this database.class.php file..

class database { public $db = null; public $libraries = null;  public function database( $config ) {     $this->connect( $config['host'], $config['user'], $config['pass'], $config['database'] ); } public function connect($host, $user, $pass, $db) {     $this->db = new mysqli( $host, $user, $pass, $db ); }  public function query( $sql ) {     $f = func_get_args( );     $i = 1;     while ( $i <= count( $f ) )     {         $args[] = addslashes( $f[$i] );         ++$i;     }     $query = $this->createquery( $sql, $args );     if ( !( $result = $this->db->query( $query ) ) )     {         exit( mysqli_error( $this->db ) );     }     return $result; }  public function fetch_assoc( $result ) {     return $result->fetch_assoc( ); }  public function createquery( $sql, $args ) {     $i = 0;     while ( $i != count( $args ) )     {         $sql = preg_replace( "/%s/", str_replace( "s", "\\s", $args[$i] ), $sql, 1 );         ++$i;     }     return $sql; } }

and template.class.php file..

public function getpageinfo( $page ) { $result = $this->database->query( "select * `content` `name` = '%s'", $page );     $row = $result->fetch_assoc( );     if ( $result->num_rows == 0 )     {         return false;     }     return $row; }

libraries included in index.php php.. first database.class.php 2nd template.class.php

and attached both files..

charles sprayberry right. code posted here either incomplete or forget create instance of database class. first thing missing in code point defined class. class mydatabase {} missing. @ least hope wanted create 1 because using $this->. second thing used $this->db in connect() function, trying use $this->database in getpageinfo() function. please provide more info class, function getpageinfo() resides , how made instance of class.
