脚本:move_uploaded_file - 图像的文件名?
<?php
if (isset($_POST['submit'])) {
$j = 0; //Variable for indexing uploaded image
$target_path = "uploads/"; //Declaring Path for uploaded images
for ($i = 0; $i < count($_FILES['file']['name']); $i++) {//loop to get individual element from the array
$validextensions = array("jpeg", "jpg", "png"); //Extensions which are allowed
$ext = explode('.', basename($_FILES['file']['name'][$i]));//explode file name from dot(.)
$file_extension = end($ext); //store extensions in the variable
$target_path = $target_path . md5(uniqid()) . "." . $ext[count($ext) - 1];//set the target path with a new name of image
$j = $j + 1;//increment the number of uploaded images according to the files in array
if (($_FILES["file"]["size"][$i] < 100000) //Approx. 100kb files can be uploaded.
&& in_array($file_extension, $validextensions)) {
if (move_uploaded_file($_FILES['file']['tmp_name'][$i], $target_path)) {//if file moved to uploads folder
echo $j. ').<span id="noerror">Image uploaded successfully!.</span><br/><br/>';
} else {//if file was not moved.
echo $j. ').<span id="error">please try again!.</span><br/><br/>';
}
} else {//if file size and file type was incorrect.
echo $j. ').<span id="error">***Invalid file Size or Type***</span><br/><br/>';
}
}
}
?>
这个脚本也可以使用多个图像上传的JavaScript。
这个脚本工作正常,但是当多个的文件无法移动到“上传”文件夹中的文件名出来是这样的:
"2f594262c1f8fb56c39cc01d4543bcb9.jpg"
"2f594262c1f8fb56c39cc01d4543bcb9.jpgf00008a16882f01d2bd7ed6d9805a4bf.jpg"
"2f594262c1f8fb56c39cc01d4543bcb9.jpgf00008a16882f01d2bd7ed6d9805a4bf.jpge967f7fbaea4e2aee9b6f56067739aed.jpg"
如何解决这个问题?

与您的问题无关,但要检查上传的文件是否属于某种类型,请不要相信该扩展名。请检查mime类型。顺便说一下,要解决您的问题,请在'for'循环中移动'$ target_path =“uploads /”;'。 – Bjorn 2014-10-12 12:34:05
