不知道为什么会发生这种事。这是我的PHP:
//Create a new function named LoggedIn, And apply database info;
function Connect($host = 'localhost',$username = 'unfed_admin',$password = 'x',$dbname = 'unfed_auth') {
//Try execute the PHP with no errors;
try {
//Create a PDO Session;
$con = new PDO("mysql:host=$host;dbname=$dbname", $username, $password);
//Session Attributes;
$con->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$con->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);
}
//Catch all PDOException errors;
catch (PDOException $e) {
//If any errors print result;
echo "<code><pre>".print_r($e)."</pre></code>";
//Make the PDO session false;
$con = false;
}
//If no errors happened Make the PDO session true;
return $con;
}
//Create a new function named query;
function query($sql = false,$bind = false,$obj = false) {
//Prepare The SQL Query;
$query = Connect()->prepare($sql);
$res = true;
//Execute Binded Query;
try { $query->execute($bind); $res = true; }
catch (PDOException $e) {
//If any errors print result;
echo "<code><pre>".print_r($e)."</pre></code>";
$res = false;
}
//If no errors happened Make $row true;
return $res;
}
//Create a new function named user_login;
function register($username = false, $email = false, $password = false) {
global $registeroutput;
//Fetch for the username and email to see if they are already used;
$fetchusername = fetch("SELECT username FROM users WHERE username = :username",array(":username"=>$username));
$fetchemail = fetch("SELECT email FROM users WHERE email = :email",array(":email"=>$email));
if(empty($fetchusername)) {
if(empty($fetchemail)) {
//Register the user;
query("INSERT INTO users (username,password,email,image) VALUES (:username,:password,:email,'test')",array(":username"=>$username),array(":password"=>$password),array(":email"=>$email));
$registeroutput = 'Success';
} else { $registeroutput = 'Email Error'; }
} else { $registeroutput = 'Username Error'; }
//If no errors happened Make the $valid true;
return true;
}
忽略PHP代码上的注释标记,它们还没有更新为相关的。我不知道为什么会发生这种事。
您在这里的数组中缺少了一点,导致当您的查询应该准备好时,参数不匹配:
query("INSERT INTO users (username,password,email,image) VALUES (:username,:password,:email,'test')",array(":username"=>$username),array(":password"=>$password),array(":email"=>$email));
为了解决这个问题,您可以进行以下更改:
query("INSERT INTO users (username,password,email,image) VALUES (:username,:password,:email,:image)",array(":username"=>$username),array(":password"=>$password),array(":email"=>$email), array(":image"=>'test'));
注意,:image
在VALUES
子句中使用,然后添加到数组中。
