[英]Not Inserting Data Into Database Table
我正在嘗試在testimage表中插入一些數據; 但是,它沒有插入。 它不會返回任何錯誤,我只知道它不會插入,因為我的插入語句有一個if / else語句。 我知道它已連接到數據庫,因為我做了一個try / catch語句。
這是我的代碼:
<?php
require_once "Connection.php";
$dbconnection = new Database('localhost', 'root', '', 'cardimages');
$Name = $_POST['cardname'];
$Colour = $_POST['colour'];
$Rarity = $_POST['rarity'];
$CardQuery = "INSERT INTO `testimage` (`Name`, `Colour`, `Rarity`) VALUES (:Name, :Colour, :Rarity)";
$CardResult = $dbconnection->Connection->prepare($CardQuery);
$CardExec = $CardResult->execute(array(":Name"=>$Name,":Colour"=>$Colour,":Rarity"=>$Rarity));
if ($CardExec) {
Echo "The data was inserted!";
} else {
echo "The data wasn't inserted!";
}
$query_array = array('name'=>$_POST['cardname'], 'type'=> 'card', '.jpg');
$url = "http://gatherer.wizards.com/Handlers/Image.ashx?".http_build_query($query_array);
$img = "Images/" . ucwords($Name) . ".png";
file_put_contents($img, file_get_contents($url));
?>
這是我的Connection.php文件:
<?php
Class Database {
private $hostname;
private $username;
private $password;
private $database;
public $Connection;
public function __construct($hostname, $username, $password, $database) {
$this->hostname;
$this->username;
$this->password;
$this->database;
$this->Connect();
}
private function SetHostname($hostname) {
$this->hostname = $hostname;
return $this;
}
private function SetUsername($username) {
$this->username = $username;
return $this;
}
private function SetPassword($password) {
$this->password = $password;
return $this;
}
private function SetDatabase($database) {
$this->database = $database;
return $this;
}
public function GetHostname() {
return $this->hostname;
}
public function GetUsername() {
return $this->username;
}
public function GetPassword() {
return $this->password;
}
public function GetDatabase() {
return $this->database;
}
private function Connect() {
try
{
$db = $this->Connection = new PDO('mysql:host=' . $this->hostname . ';dbname=' . $this->database . '', $this->username, $this->password);
echo "This connected successfully!";
}
catch (PDOException $e)
{
echo "It didn't connect to the database!";
}
}
}
?>
Database :: __ construct的前4行是什么?
提示: $this->hostname=$hostname;
或$this->SetHostname($hostname)
當前也許(但是我不這么認為)連接有效,但是從不選擇cardimages
