check_em() が成功すると、何らかの理由で return が機能しません。私はphpが初めてなので、ここで途方に暮れています。
<?php
//Class to handle mysql
class db_handler {
private $db_host = 'localhost';
private $db_name = 'project';
private $db_user = 'project';
private $db_pass = 'dbpassword';
private $db_con_mysql = '';
private $db_con_db = '';
public function check_em($username, $password) {
$db_query = "SELECT password FROM user WHERE name='".$username."' LIMIT 1;";
if($this->db_con_mysql!='') {
$db_query_response = mysql_query($db_query) or die('Query failed: '.mysql_error());
$db_query_return = mysql_fetch_row($db_query_response);
$db_sha1_hash = $db_query_return[0];
echo $db_sha1_hash."<br>";
echo sha1($password)."<br>";
if(sha1($password)==$db_sha1_hash) {
return 'user valid'; //THIS DOESN'T WORK!?!?!?
} else {
return 'no good';
}
} else {
$this->db_connect();
$this->check_em($username, $password);
}
}
//Connect to mysql, then database
private function db_connect() {
$this->db_con_mysql = mysql_connect($this->db_host, $this->db_user, $this->db_pass) || die('Connection failed: '.mysql_error());
$this->db_con_db = mysql_select_db($this->db_name) || die('Could not use'.$this->db_name.'. '.mysql_error());
return;
}
//Disconnect from database and reset vars used to track connection.
private function db_disconnect() {
if($this->db_con_mysql!='') {
mysql_close();
$this->db_con_mysql = '';
$this->db_con_db = '';
return;
}
}
public function fake($some_val) {
if($some_val<6) {
return TRUE;
} else {
return FALSE;
}
}
}
$db_obj = new db_handler();
$val1 = $db_obj->check_em('someuser','password'); //should return 'user valid'
echo "val1:".$val1."<br>";
echo "<br><br>";
$val2 = $db_obj->check_em('someuser','passw0rd'); //should return 'no good'
echo "val2:".$val2."<br>";
echo "<br><br>";
echo "test<br>";
echo $db_obj->fake(4)."<br>";
?>
結果:
