我想调整一个图像上传到我的PHP窗体上。图片正在保存，但没有调整大小。基本上，除了图像部分的大小调整以外，一切工作都很好。我把我的代码放在下面。php图片调整大小不能在图像上传
HTML表单与PHP重新上浆
<?php include "base.php"; ?>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01

"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<title>Submit an Album</title>
</head>
<body>
<?php
if(isset($_POST['submit'])) {
include('SimpleImage.php');
$image = new SimpleImage();
$image->load($_FILES['albumCover']['tmp_name']);
$image->resize(150,150);
$image->output();
} else {
?>
<table>
<tr>
<td align="center">Submit an Album</td>
</tr>
<tr>
<td>
<table>
<form enctype="multipart/form-data" action="submitAlbumForm.php" method="post">
<tr>
<td>Artist Name</td>
<td><input type="text" name="artistName" size="20">
</td>
</tr>
<tr>
<td>Album Name</td>
<td><input type="text" name="albumName" size="20">

</tr>
<tr>
<tr>

<tr>
<tr>
<td>Where It Leaked</td>
<td><input type="text" name="whereItLeaked" size="20">
</td>
</tr>
<tr>
<tr>
<td>Album Cover</td>
<td><input type="file" name="albumCover">
</td>
</tr>
<tr>
<td></td>
<td align="right"><input type="submit" name="submit" value="Add"></td>
</tr>
</form>
</table>
</td>
</tr>
</table>
<?php
}
?>
</body>
</html>
submitAlbumForm.php，php的形式上传表单信息数据库
<?php
include "base.php";
//Setting up images directory
$target = "images/";
$target = $target . basename($_FILES['albumCover']['name']);
$albumCover=($_FILES['albumCover']['name']);
//inserting data order
$order = "INSERT INTO albums
(artistName, albumName, releaseDate, leakDate, whereItLeaked, albumCover)
VALUES
('$_POST[artistName]',
'$_POST[albumName]',
'$_POST[releaseDate]',
'$_POST[leakDate]',
'$_POST[whereItLeaked]',
'{$_FILES['albumCover']['name']}')";
//Writes image to database
mysql_query("INSERT INTO `albums` VALUES ('albumCover')") ;
if(move_uploaded_file($_FILES['albumCover']['tmp_name'], $target))
{
//Tells you if its all ok
echo "The file ". basename($_FILES['uploadedfile']['name']). " has been uploaded, and your information has been added to the directory";
}
else {
//Gives an error if its not
echo "Sorry, there was a problem uploading your file.";
}
//declare in the order variable
$result = mysql_query($order); //order executes
if($result){
echo("<br>Thank you for submitting!");
} else{
echo("<br>Sorry, something went wrong! Please try again!");
}
?>

我知道我现在有很多安全漏洞，并将工作在那些很快！多谢你们！
所以..您是希望我们阅读所有？在哪里_exactly_出错了？这会更有帮助;） – Bono 2012-08-03 17:58:46
Stackoverflow不是一个调试服务。您必须提出与编程有关的具体问题，向我们展示**代码的相关**部分（而不是数百行），并且有人可以为您提供帮助。 – Jocelyn 2012-08-03 18:02:35
对不起，我想我不是很清楚哈哈，除了在html表格中的php片段，一切都工作正常，它实际上并没有调整大小和保存图像，然后将其上传到我的数据库。 – user1570257 2012-08-03 18:02:54
