我正嘗試從我的網站使用PHP將一些信息寫入SQL數據庫。我可以訪問數據庫進行登錄,但是我無法從我的網站上寫入任何內容。此外,我無法查看任何連接錯誤。無法將數據寫入sql表中,
窗體頁:
<?php
$dbh = new PDO('mysql:host='.$hostname.';dbname='.$dbname, $user, $pass);
if (!$dbh) { die('Could not connect: ' . mysql_error()); }else echo 'connected';echo '<br>';
if(isset($_COOKIE['username']))
?>
<div id="imagel">
<img class="imagel" src="../images/logos/logo2.jpg" width="300" height="300" alt="studio table" />
</div>
<div id="textr">
<form name="tableofevents" method="post" action="adminhome.php">
Name of Event(Maximum of 83 characters): <input type="text" name="noe"/>
<br>
Event Description (Maximum of 288 characters): <input type="text" name="eventdescription"/>
<br>
Date of Event: <input type="text" name="date"/>
<br>
Ticket Price: <input type="text" name="price"/>
<br>
<input type="submit" name="submit" text="submit"/>
</form>
處理頁面:
<?php
$hostname = 'localhost';
$user='******';
$pass='***********';
$dbname='sth420';
$handler = new PDO('mysql:host='.$hostname.';dbname='.$dbname,$user,$pass);
$dbh = mysql_connect ($hostname.';dbname='.$dbname, $user, $pass);
if (!$dbh) { die('Could not connect: ' . mysql_error()); }
else echo 'connected';echo '<br>';
if(isset($_COOKIE['username']))
{
$username=$_COOKIE['username'];
$password=$_COOKIE['password'];
$sql='SELECT * FROM Users WHERE ID=:id';
$results = $handler->prepare($sql);
$results->execute([':id' => $username]);
$row = $results->fetch();
if($row!=null)
{
$pword = $row['Password'];
if($pword == $password)
{
if(isset($_POST['submit']))
{
$noe=$_POST['noe'];
$ed=$_POST['eventdescription'];
$date=$_POST['date'];
$price=$_POST['price'];
$sql='INSERT INTO ismievents (title, evtdesc, dandt, price) VALUES(0, :noe, :eventdescription, :date, :price)';
mysql_error()
$results = $handler->prepare($sql);
$results->execute([':noe' => $noe, ':eventdescription' => $ed, ':date' => $date, ':price' => $price]);
$handler = null;
header('Location: events.html');
}
}
}
}
if (!mysql_query($sql,$dbh))
{
die('Error: ' . mysql_error());
}
echo "1 record added";
mysql_close($dbh);
require_once('adminhome.html');
?>
爲什麼你在表單頁面上有數據庫連接?確保在流程中的每個步驟都包括錯誤處理(例如執行'$ handler',準備語句,執行語句等,並註銷錯誤,以便您可以確切地知道錯誤發生的位置。 –
