Please be patient. I’m doing writing custom code for you on weekend for free.
STEP 1. Make a backup of your theme’s functions.php file in case you mess up adding this custom code. It is always recommended to backup this file before making any modifications because it is such an important file.
Paste in the following code at the very top after the opening <?php
// Tell HD Quiz to run a function once the quiz has been completed
function hdq_faradaydeman_submit($quizOptions)
{
array_push($quizOptions->hdq_submit, "hdq_faradaydeman_submit");
return $quizOptions;
}
add_action('hdq_submit', 'hdq_faradaydeman_submit');
// Add new custom "redirect" field to quiz settings results tab
function hdq_faradaydeman_add_custom_fields_to_quizzes($fields)
{
// slug of the tab you want to add the field to
$tab = "results";
// Set the tab (used in case this is a non default tab)
if (!isset($fields[$tab]) || !is_array($fields[$tab])) {
$fields[$tab] = array();
}
// set field settings
$field = array();
$field["name"] = "hdq_redirect"; // should be slug format
$field["label"] = "Redirect link";
$field["type"] = "text";
$field["placeholder"] = "https://";
array_push($fields[$tab], $field);
return $fields;
}
add_action('hdq_add_quiz_meta', 'hdq_faradaydeman_add_custom_fields_to_quizzes');
// add custom function that will run once the quiz has been completed
function hdq_faradaydeman_redirect($quiz_id)
{
$quiz_settings = get_hdq_quiz($quiz_id);
if (isset($quiz_settings["hdq_redirect"]["value"]) && $quiz_settings["hdq_redirect"]["value"] != null) {
$redirect = $quiz_settings["hdq_redirect"]["value"];
hdq_faradaydeman_print_redirect($redirect);
}
?>
<script>
function hdq_faradaydeman_submit() {
if (typeof hdq_redirect_url != "undefined") {
setTimeout(function() {
window.location.replace(hdq_redirect_url);
}, 3000); // 3000 = 3seconds.
}
}
</script>
<?php
}
add_action('hdq_after', 'hdq_faradaydeman_redirect');
function hdq_faradaydeman_print_redirect($redirect)
{
?>
<script>
let hdq_redirect_url = "<?php echo $redirect; ?>";
</script>
<?php
}
The above code does the following:
1. Adds a new textbox to the quiz settings results page where you can add in a redirect link.
2. On quiz load, detects if a redirection link exists, if it does exist, then we set up a custom function to run once the quiz has been completed.
3. we run our custom function, which in this case, is to redirect to a new page after 3 seconds.
The only thing you might want to modify is the number 3000 in the hdq_faradaydeman_submit function. This number represents 3seconds (in milliseconds) – the time we wait to redirect. Changing this to 0 will make the redirection instant, and changing it to 10000 will make it redirect after 10 seconds.
