Well, I admit I'm a wuss.

Today in the Laravel framework to write a file upload part. The discovery path always does not match. But eventually it was settled.

Let me share my learning experience below.

Client

<form method= "POST" action= "enctype=" Muitipart/form-data ">

<input type= "File" name= "MyFile"/>

<input type= "Submit" name= "submit" value= "Submit"/>

</form>

Submit to the server side.

$file = Input::file (' myfile ');

if ($file, IsValid ()) {

Verify that the uploaded file is valid.

$clientName = $file-Getclientoriginalname (); //Client file name:

$tmpName = $file->getfilename (); // cache filenames in the TMP folder such as php8933.tmp of this type.

$realPath = $file-Getrealpath (); This represents the absolute path of the file that is cached in the TMP folder

For example mine is:G:\xampp\tmp\php5A69.tmp

Note here that if I use the next Move method, Getrealpath () will not find the path to the file. Because the file has been moved.

So here's how the file is uploaded, a temporary directory where the file is uploaded, and then the PHP function is used to move the file to the specified folder.

$entension = $file-Getclientoriginalextension (); The suffix of the upload file.

$mimeTye = file-GetMimeType ();//mimetype should not be unfamiliar to everyone. The result I got was image/jpeg.

One thing to note here is that before we used Mime_content_type (), after php5.3, we started using FileInfo to get the MIME type of the file. So join the PHP_ FileInfo PHP extension. Under Windows is Php_fileinfo.dll, remove the semicolon from the front extension=php_fileinfo.dll in the php.ini file. Of course, restart the server.

Finally we use

$path = Move (' storage/uploads '), $file

If you write like this, the default will be placed in our public/storage/uploads/php79db.tmp

It looks like it's not what we want, if we want to place it in the uploads directory in the app's storage directory, and we need to rename it.

$path = Move (App_path () $file. /storage/uploads ', $newName);

here App_path () is the path where the app folder is located. $newName can be the name of a file that you get through an algorithm. It is not possible to repeat the conflict. for example $newName = MD5 (date (' Ymdhis '). $clientName). ".". $extension;

Use the date and client file names in conjunction with the MD5 algorithm to encrypt the results. Don't forget to add the original extension name to the file later.

Well, I started to write a program, and now it's a virtue.

Best Wishes.
