Introduction

This example will run a natural horizontal ProgressBar and show you how to use a picture instead of simple color for active cells.

Percent text info is centered on a 60 pixels width area, on left side of the progress bar.

PHP script

Build the progress bar


require_once 'HTML/Progress.php';

$bar = new HTML_Progress();
$bar->setAnimSpeed(100);
$bar->setIncrement(10);
$bar->setBorderPainted(true);

$ui =& $bar->getUI();
$ui->setCellAttributes(array(
    'active-color' => '#000084',
    'inactive-color' => '#3A6EA5',
    'width' => 25,
    'spacing' => 0,
    'background-image' => 'download.gif'
));
$ui->setBorderAttributes('width=1 style=inset color=white');
$ui->setStringAttributes(array(
    'width' => 60,
    'font-size' => 10,
    'background-color' => '#C3C6C3',
    'align' => 'center',
    'valign' => 'left'
));

Loop to run the progress


do {
    $bar->display();
    if ($bar->getPercentComplete() == 1) {
        break;   // the progress bar has reached 100%
    }
    // your user-process should be put HERE !
    $bar->incValue();
} while(1);

HTML_Progress_UI::setCellAttributes()
