上载时未找到PHPthumbFactory文件

图书馆：

我正在使用PhpThumbFactory库裁剪和上载图像。im接收到的错误如下：

Fatal error: Uncaught exception 'Exception' with message 'Image file not found: ' in /www/iaddesign/admin/classes/phpthumb/ThumbBase.inc.php:193 
Stack trace: 
#0 /www/iaddesign/admin/classes/phpthumb/ThumbBase.inc.php(172): ThumbBase->triggerError('Image file not ...')

#5 {main} thrown in /www/iaddesign/admin/classes/phpthumb/ThumbBase.inc.php on line 193

下面是要上载的图像的代码段

/* -------------------------------------------------------------------- */
/*                        SAVE ICONS                                    */
/* -------------------------------------------------------------------- */

$icononsrc = $_FILES['iconoff']['tmp_name'];
$iconoffsrc = $_FILES['iconon']['tmp_name'];

$thumboff = PhpThumbFactory::create($iconoffsrc);
$thumbon = PhpThumbFactory::create($icononsrc);

$thumboff->adaptiveResize(200,151);
$thumbon->adaptiveResize(200,151);

$thumboffname = "uploads/".$_FILES['iconoff']['name'];
$thumbonname = "uploads/".$_FILES['iconon']['name'];

$thumboff->save($thumboffname, 'jpg');
$thumbon->save($thumbonname, 'jpg');

检查文件是否存在且可读时，从堆栈跟踪

#1 [cut] ThumbBase.inc.php(110): ThumbBase->fileExistsAndReadable() 

抛出一个错误

#0 [cut] ThumbBase.inc.php(172): ThumbBase->triggerError('Image file not ...') 

（请记住堆栈跟踪以相反的顺序出现）

我可以由此推断，您试图转换的文件名不存在，或者存在权限问题。确保该文件存在并具有适当的读取权限。

错误说明并非如此。请尝试使用

文件\u exists（）

验证文件内容，或回显数据以确保正确。您在这方面取得了进一步的进展吗？
