我正在尝试使用 PHP 从我的网站将一些信息写入 SQL 数据库。我可以访问数据库进行登录,但是我无法从我的网站向其中写入任何内容。此外,我无法查看任何连接错误。
表格页面:
<?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>
处理页面:
<?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');
