我使用POST方法在upload_photo.php文件中上传照片,该文件使用uploader.php来处理图像. Uploader.php将调整图像大小并覆盖旧图像.它在本地工作正常,但不在服务器上.
move_uploaded_file返回false,但是$_FILES [‘uploadedfile’] [‘error’] == 0这对我来说没有.
我已经发布了整个uploader.php和来自upload_photo.php的片段,其中显示了表单标签.
<?php
//This is uploader.php
session_start();
include ('dbconfig.php');
include('SimpleImage.php');
mysql_connect(HOST, USERNAME, PASSWORD);
$conn = mysql_select_db(DB_NAME);
$target_path = "uploads/";
$target_path = $target_path . renameImage();
$_SESSION['client_photo'] = $target_path;
$query = "UPDATE client ";
$query .= "SET personal_photo = ('$target_path') ";
$query .= "WHERE client_id = ".$_SESSION['clientID'];
$results = mysql_query($query) or die('Error msg: '.mysql_error().'<br/>
sql: '.query.'<br/>');
if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
$msg = "The file ". $_SESSION['client_photo'].
" has been uploaded";
chmod($target_path, "0666");
$work = new ImgResizer($target_path);
$work -> resize(600, $target_path);
} else{
$msg = "There was an error uploading the file, please try again!";
$msg .= $_FILES['uploadedfile']['error'];
}
header("Location: upload_photo.php?msg=$msg");
function renameImage(){
mysql_connect(HOST, USERNAME, PASSWORD);
$conn = mysql_select_db(DB_NAME);
$sql = "SELECT first_name, last_name, client_id
FROM client
WHERE client_id = ".$_SESSION['clientID'];
$res = mysql_query($sql) or die('Error msg: '.mysql_error().'<br/>
sql: '.$sql.'<br/>');
if($row = mysql_fetch_array($res, MYSQLI_ASSOC)){
$_SESSION['successphoto'] = 1;
return $row{first_name}.'_'.$row{last_name}.'_'.$row{client_id};
}
else{
echo "There was an error while fetching the row.<br/>";
}
}
class ImgResizer {
private $originalFile = '';
public function __construct($originalFile = '') {
$this -> originalFile = $originalFile;
}
public function resize($newWidth, $targetFile) {
if (empty($newWidth) || empty($targetFile)) {
return false;
}
$src = imagecreatefromjpeg($this -> originalFile);
list($width, $height) = getimagesize($this -> originalFile);
$newHeight = ($height / $width) * $newWidth;
$tmp = imagecreatetruecolor($newWidth, $newHeight);
imagecopyresampled($tmp, $src, 0, 0, 0, 0, $newWidth, $newHeight, $width, $height);
if (file_exists($targetFile)) {
unlink($targetFile);
}
imagejpeg($tmp, $targetFile, 85); // 85 is my choice, make it between 0 – 100 for output image quality with 100 being the most luxurious
}
}
?>
以下是upload_photo.php的片段
echo '<form enctype="multipart/form-data" action="uploader.php" method="POST">';
echo '<tr>';
//echo "<td colspan='2'>".$_GET['text']."</td>";
echo '</tr>';
echo '<tr align="center">';
echo '<td colspan="2">';
echo '<input type="hidden" name="MAX_FILE_SIZE" value="5000000" />
Choose a file to upload: <input name="uploadedfile" type="file" accept="image/*"/><br />
<input type="submit" value="Upload File" />
</form>';
解决方法:
这可能意味着上传运行正常 – 文件上传到临时目录 – 但文件无法移动到您设置的目标.
您应该仔细检查要将文件移动到的路径,并确保Web用户(apache,www或其他)有权写入该目录.
