[英]Image upload, not recognising file extension
我已使用本教程構建圖像上傳器。
http://www.codeforest.net/upload-crop-and-resize-images-with-php
這使用圖書館
https://gist.github.com/philBrown/880506/download#
但是,當我通過表單將文件傳遞給它時,它總是在最后一個IF語句上失敗(請上傳圖片)
下面是代碼:
<?php
require_once(dirname(__FILE__).'/../config.php');
require_once(dirname(__FILE__).'/ImageManipulator.php');
if ($_FILES['fileToUpload']['error'] > 0) {
echo "Error: " . $_FILES['fileToUpload']['error'] . "<br />";
} else {
// array of valid extensions
$validExtensions = array('.jpg', '.jpeg', '.gif', '.png', '.JPG', '.JPEG', '.PNG', '.GIF', '.bmp');
// get extension of the uploaded file
$fileExtension = strrchr($_FILES['fileToUpload']['name'], ".");
// check if file Extension is on the list of allowed ones
if (in_array($fileExtension, $validExtensions)) {
$newNamePrefix = time() . '_';
$manipulator = new ImageManipulator($_FILES['fileToUpload']['tmp_name']);
$width = $manipulator->getWidth();
$height = $manipulator->getHeight();
$centreX = round($width / 2);
$centreY = round($height / 2);
// our dimensions will be 80by80
$x1 = $centreX - 40; // 80
$y1 = $centreY - 40; // 80
$x2 = $centreX + 40; // 80
$y2 = $centreY + 40; // 80
// center cropping to 80by80
$newImage = $manipulator->crop($x1, $y1, $x2, $y2);
// saving file to uploads folder
$manipulator->save('/images/avatars/uploaded/' . $newNamePrefix . $_FILES['fileToUpload']['name']);
echo 'Done ...';
} else {
echo 'You must upload an image...';
}
}
?>
這是表格。
<h4>Change Avatar</h4>
<form enctype="multipart/form-data" method="post" action="/lib/uploadimage.php"><table class="table table-striped">
<tr><td>Please choose a file:</td><td><input type="file" name="fileToUpload" id="fileToUpload" />
<tr><td colspan="2"><input type="submit" value="Upload"></td></tr>
</table></form>
一旦完成這項工作,我就計划將URL插入數據庫。
我假設它在上載方面失敗,但是apache日志不會給我任何錯誤,並且該文件夾具有757權限。
知道為什么這失敗了嗎?
編輯:通過Apache的錯誤是
log:[Sat Jul 19 20:48:51 2014] [error] [client 82.46.57.58] PHP Notice: Undefined index: fileToUpload in /var/SITE/lib/uploadimage.php on line 5, referer: SITE/index.php
編輯:深入挖掘,這似乎是一個權限問題
SITE:[Sat Jul 19 21:31:58 2014] [error] [client 82.46.57.58] PHP 2. ImageManipulator->save() /SITE/lib/uploadimage.php:30, referer: SITE/index.php

SITE:[Sat Jul 19 21:31:58 2014] [error] [client 82.46.57.58] PHP Fatal error: Uncaught exception 'RuntimeException' with message 'Error creating directory /images/avatars/uploaded' in /SITE/lib/ImageManipulator.php:223\nStack trace:\n#0 /SITE/lib/uploadimage.php(30): ImageManipulator->save('/images/avatars...')\n#1 {main}\n thrown in /SITE/lib/ImageManipulator.php on line 223, referer: SITE/index.php
這是基於權限的,並且圖像目錄中有一個小錯誤。
它應該是../images,文件夾必須由www-data擁有。
