This project scope came about when a comment was received asking how to use a seconds timed delay. So I put a blog together on this. The original progress bar was jerky in nature and did not look professional.
While updating the blog to Bootstrap 4, the scope required a smooth progressbar showing the seconds counting down.
Bootstrap 4 Framework –download here.
PHP 5.6 + download here .
Downloader.php - A PHP Library (A free to use file download library created by Jack Mason )
This is included in the included Download below.
This file contains the visual element of a drop down box to select the file to download.
This file contains the visual download progress bar and button to download the file.
This file is called by the download button and processes the file to download.
This holds all the mime information and allows any type of file to be downloaded.
To show and hide classes, the class “hidden” is no longer for bootstrap 4. This is replaced with class = ”d-none” to perform the same functionality.
Whilst the progress bar (width) is updating at 10 times the speed, the second value is updated when the ‘proglevel’ (check code below) value equals the value of a second then this triggers the title in the progress bar to update the seconds value.
To adjust the delay in seconds, change only the variable ‘seconds = 20’ to for example ‘seconds = 40’.
You can download the full code for the project at the end of the blog
