PHP download & directory functions
The SELECT menu shows all uploaded files and after a file is selected, the PHP download script will open the file and sends the data to your web browser.
The download of files is on your own risk! Download only the file(s) you've uploaded before.
Directories oldest file
I use this script to remove the oldest files at the moment a new file has been uploaded.
Create a SELECT menu from a directory
All files from the upload directory are selected and parsed using PHP directory functions. This custom function creates a select menu for all the files. The value from that select element is posted to the download form.
Relevant PHP functions
- move_uploaded_file checks that the file is a valid upload file. If the file is valid, it will be moved to the given destination.
- is_uploaded_file returns TRUE if the file named by filename was uploaded before.
- readdir returns the name of the next entry in the directory. The entries are returned in the order in which they are stored by the filesystem.
- fread reads up to length bytes from the file pointer referenced by handle. Reading stops as soon as length bytes have been read or the end of file is reached.
We remove all uploaded files frequently. Please keep this demo clean and upload only those files you like to have on your own website!
