This example shows how to set report variable values on the server side using Stimulsoft Viewer for PHP. First, you need to include the Stimulsoft libraries:

<?php
require_once '../vendor/autoload.php';

use Stimulsoft\Events\StiVariablesEventArgs;
use Stimulsoft\Report\StiReport;
use Stimulsoft\Viewer\StiViewer;
?>

Next, create a Viewer object and configure JavaScript-related options:

$viewer = new StiViewer();
$viewer->javascript->relativePath = '../';
$viewer->javascript->appendHead('<link rel="shortcut icon" href="/../favicon.ico" type="image/x-icon">');

Next, define viewer events before processing. You can assign a PHP function, the name of a JavaScript function, or a JavaScript function as a string. Multiple event handlers can be added using the append() method. In this example, the onPrepareVariables event is used to set report variable values:

$viewer->onPrepareVariables = function (StiVariablesEventArgs $args) {
    if (count($args->variables) > 0) {
        $args->variables['Name']->value = 'Maria';
        $args->variables['Surname']->value = 'Anders';
        $args->variables['Email']->value = 'm.anders@stimulsoft.com';
        $args->variables['Address']->value = 'Obere Str. 57, Berlin';
        $args->variables['Sex']->value = false;
        $args->variables['BirthDay']->value = '1982-03-20 00:00:00';
    }
};

After defining events, process the request on the server side using process():

$viewer->process();

Next, create a report object and load a report template. The loadFile() method does not load the report on the server side; it only generates JavaScript code to load the report on the client side:

$report = new StiReport();
$report->loadFile('../reports/Variables.mrt');

Assign the report to the viewer:

$viewer->report = $report;

Finally, render the viewer as a complete HTML page using printHtml():

$viewer->printHtml();
