如何将文件移动到另一个文件夹使用PHP？ [英] How can I move a file to another folder using php?
问题描述
我有一个上传表单，用户可以上传当前上传的图片到我称之为temp的文件夹，他们的位置保存在名为$ _SESSION ['uploaded_photos']的数组中。一旦用户按下下一页按钮，我希望它将文件移动到一个新的文件夹，该文件夹是在此之前动态创建的。
if（isset（$ _ POST ['next_page']））{
if（！is_dir（'../ images / uploads / listers /'.$_ SESSION ['loggedin_lister_id']））{
mkdir（'../ images / uploads / listers /'.$_ SESSION ['loggedin_lister_id']）;
foreach（$ _ SESSION ['uploaded_photos'] as $ key => $ value）{
$ target_path ='../images/uploads/listers/' 。$ _ SESSION [ 'loggedin_lister_id' '/'。
$ target_path = $ target_path。基本名（$值）;
if（move_uploaded_file（$ value，$ target_path））{
echoThe file。基本名（$值）。 已上传< br />;
} else {
echo上传文件时出现错误，请重试！;
}
} // end foreach
} // end if isset next_page
正在使用的$值的例子是：
lockquote
../ images /uploads/temp/IMG_0002.jpg
正在使用的$ target_path的示例是：
../ images / uploads / listers / 186 / IMG_0002.jpg
我可以看到临时文件夹中的文件，这两个路径对我来说都很好，我检查确认mkdir函数实际上创建了它的文件夹。
如何使用php将文件移动到另一个文件夹？
当我阅读你的场景时，看起来你已经处理了上传，并将文件移动到你的临时文件夹，现在你想要在文件执行新动作（点击下一步按钮）时移动文件。就PHP而言 - 你的'temp'中的文件不再是上传的文件，所以你不能再使用move_uploaded_file。
所有你需要做的就是使用重命名：
if（isset（$ _ POST ['next_page']））{
if（！is_dir（'../ images / uploads / listers /'.$_ SESSION ['loggedin_lister_id']））{
mkdir （ '../images/uploads/listers/'.$_SESSION['loggedin_lister_id']）;
foreach（$ _ SESSION ['uploaded_photos'] as $ key => $ value）{
$ target_path ='../images/uploads/listers/' 。$ _ SESSION [ 'loggedin_lister_id' '/'。
$ target_path = $ target_path。基本名（$值）;
if（rename（$ value，$ target_path））{
echoThe file。基本名（$值）。 已上传< br />;
} else {
echo上传文件时出现错误，请重试！;
}
} // end foreach
} // end if isset next_page
I have an upload form where users can upload images that are currently being uploaded to a folder I made called 'temp' and their locations are saved in an array called $_SESSION['uploaded_photos']. Once the user pushes the 'Next Page' button, I want it to move the files to a new folder that is dynamically created right before that.
if(isset($_POST['next_page'])) {
if (!is_dir('../images/uploads/listers/'.$_SESSION['loggedin_lister_id'])) {
mkdir('../images/uploads/listers/'.$_SESSION['loggedin_lister_id']);
}
foreach($_SESSION['uploaded_photos'] as $key => $value) {
$target_path = '../images/uploads/listers/'.$_SESSION['loggedin_lister_id'].'/';
$target_path = $target_path . basename($value);
if(move_uploaded_file($value, $target_path)) {
echo "The file ". basename($value). " has been uploaded<br />";
} else{
echo "There was an error uploading the file, please try again!";
}
} //end foreach
} //end if isset next_page
An example for a $value that is being used is:
../images/uploads/temp/IMG_0002.jpg
And an example of a $target_path that is being used is:
../images/uploads/listers/186/IMG_0002.jpg
I can see the file sitting in the temp folder, both of those paths look good to me and I checked to make sure that the mkdir function actually created the folder which it did well.
How can I move a file to another folder using php?
As I read your scenario, it looks like you've handled the upload and moved the files to your 'temp' folder, and now you want to move the file when they perfom a new action (clicking on the Next button).
As far as PHP is concerned - the files in your 'temp' are not uploaded files anymore, so you can no longer use move_uploaded_file.
All you need to do is use rename:
if(isset($_POST['next_page'])) {
if (!is_dir('../images/uploads/listers/'.$_SESSION['loggedin_lister_id'])) {
mkdir('../images/uploads/listers/'.$_SESSION['loggedin_lister_id']);
}
foreach($_SESSION['uploaded_photos'] as $key => $value) {
$target_path = '../images/uploads/listers/'.$_SESSION['loggedin_lister_id'].'/';
$target_path = $target_path . basename($value);
if(rename($value, $target_path)) {
echo "The file ". basename($value). " has been uploaded<br />";
} else{
echo "There was an error uploading the file, please try again!";
}
} //end foreach
} //end if isset next_page
