How to Display AJAX Upload Progress with a `` Element?

Displaying AJAX Upload Progress with a Progress Element

When working with lengthy file uploads via AJAX, it's crucial to provide users with visual feedback on the progress. This article aims to address this problem by exploring how to update a element in real-time to indicate the upload's status.

In your executing class, you have a $progress property that tracks the upload's progress and a get_progress() method to retrieve this value. The challenge lies in accessing this same instance on the front end through AJAX.

No-JavaScript Solution

Although AJAX is a common solution, if your requirement is to display progress without using JavaScript, consider using the following PHP script:

// Quick and easy progress script
$array1 = array(2, 4, 56, 3, 3);
$current = 0;

foreach ($array1 as $element) {
    $current++;
    outputProgress($current, count($array1));
}
echo "<br>";

// Second progress
$array2 = array(2, 4, 66, 54);
$current = 0;

foreach ($array2 as $element) {
    $current++;
    outputProgress($current, count($array2));
}

// Output span with progress
function outputProgress($current, $total) {
    echo "<span>
Copy after login

This script iterates through arrays and outputs the progress as spans with percentages in a loop. The function myFlush() ensures that the output is sent immediately, allowing the progress to be displayed in real-time.
