HomeBackend DevelopmentPHP Tutorial小白求帮助~uploadify图片上传问题

遇到个php问题 我用uploadify插件上传图片失败了 不知道是什么原因 插件也没跟我报错 我后台echo了发现move_uploaded_file()返回个false 函数的两个参数都对 然后发现在临时文件夹/private/var/tmp/就没生成要上传的文件 p.s.我用的mac当服务器 是系统权限的问题么?


回复讨论(解决方案)

上传的文件仅为此次请求保留,也就是说你的代码一结束,这个临时文件就会被销毁,你也就不可能看到。
这种情况大多和目标目录的权限有关,需要给目标目录所有人可写权限

已经给everyone读和写的权限了 还是不行 求助~

$to = 要移动到新目录的文件;var_dump($FILES, $to, is_writable(dirname($to)));

看看什么结果

PHP code?12$to = 要移动到新目录的文件;var_dump($FILES, $to, is_writable(dirname($to)));
看看什么结果

string(26) "/private/var/tmp/phpctmJJV"
string(77) "/Library/WebServer/Documents/handler/uploads/6573d7a11f3e8ed173239f20e3de3f7d"
bool(false)

怎么解决呢?

/Library/WebServer/Documents/handler/uploads/ 没有所有人可写权限,所以 is_writable 返回false

/Library/WebServer/Documents/handler/uploads/ 没有所有人可写权限,所以 is_writable 返回false

string(26) "/private/var/tmp/phpURXYCu"
string(77) "/Library/WebServer/Documents/handler/uploads/b4f1262969d27fee9c4a867a8d109573"
bool(true)
现在给权限了 然后发现uploads文件夹里还是空的 呃。。

那这回 move_uploaded_file() 返回的还是false吗,你是怎么调用它的?
试试这样:

$from = "/private/var/tmp/phpURXYCu"; // 源文件 $_FILES['name']['tmp_name']$to = "/Library/WebServer/Documents/handler/uploads/b4f1262969d27fee9c4a867a8d109573";var_dump( is_readable($from), file_put_contents($to, file_get_contents($from)));

如果返回的是 true false 那我也不知道是什么情况了

那这回 move_uploaded_file() 返回的还是false吗,你是怎么调用它的?
试试这样:

PHP code?123$from = "/private/var/tmp/phpURXYCu"; // 源文件 $_FILES['name']['tmp_name']$to = "/Library/WebServer/Documents/handler/up……

好了 是我2了 move的代码让我//了 现在OK了 多谢~

Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.
