PHP上传文件未显示在服务器上

Question

I am writing a PHP to upload .PDF's to my server. Currently When I "upload" the file the system acts as if the task was completed, yet the file does not show up in the designated folder.

Form Code

<form id="add" action="action.php" method="post" enctype="multipart/form-data">
    <table><tr><td>
         <input type="file" name="uploadedfile" id="uploadedfile" required />
    </td></tr><tr><td>
         <input id="upload" type="submit" value="Upload">
    </td></tr></tr></table></form>

PHP Code

move_uploaded_file($_FILES["uploadedfile"]["tmp_name"],"Flyers/".$_FILES["uploadedfile"]["name"]);

Answer 1

I think the problem might be that you're trying to write to the folder that the script is running in but you need to give it a full path..

Try: move_uploaded_file($_FILES["uploadedfile"]["tmp_name"],"/Flyers/".$_FILES["uploadedfile"]["name"]);

with a / before the Flyers and make sure there is a Flyers directory in the root of the server eg. public_html/Flyers

and that it is writeable. (Your ftp client should give you some way of checking the permissions on a folder.)

Answer 2

First of all, it is always a good idea to use absolute paths instead of relative paths as you may "get lost" with all the different files you may be using.

move_uploaded_file($_FILES["uploadedfile"]["tmp_name"], __DIR__ . "/Flyers/".$_FILES["uploadedfile"]["name"]);

__DIR__ is the directory the script that contains this code resides in, change it accordingly

Secondly, you should check the return of move_uploaded_file to see if it was successful. This function returns a boolean , so if it was true then you know it was successful, otherwise somethine went wrong.

Usually it is folder permissions. If your webserver was not configured properly there maybe permission issues where the user that is running PHP does not have proper permissions to the folder and may be denied permission to write to that folder, which will break move_uploaded_file .

To solve this, you will need to fix your server config... which I will not cover here as there are too many variables that will affect this. But you can try to set 777 or 775 permission to the folder you wish to upload to, either with your ftp software, ssh, or within php with chmod or umask (search them on PHP docs to see how to use)
