Show or Change a field value depending the date

Hi @salgraphics

I hope you are doing well.

I made a couple of tests on my lab site and I believe with a small code we can help you here.

Could you give it a try at

– Add a hidden field, select “Custom value” and use {custom_day_value} as the default value:

– We will update the value depending on the day of the month example 35 or 40 in your case,

– So you can use it to make any calculation or visibility rule:

For this, add this code as a mu-plugin:

<?php 

add_action('forminator_custom_form_submit_before_set_fields', 'wpmudev_change_hidden_field_custom', 10, 3);
function wpmudev_change_hidden_field_custom($entry, $module_id, $field_data_array)
{
    $form_ids = array(6); // Please change the form ID.
    if (!in_array($module_id, $form_ids)) {
        return;
    }

    foreach ($field_data_array as $key => $value) {
        if (strpos($value['name'], 'hidden-1') !== false) {
            Forminator_CForm_Front_Action::$info['field_data_array'][$key]['value'] = sanitize_text_field(Forminator_CForm_Front_Action::$prepared_data['hidden-1']);
        }
    }
}

add_filter('forminator_field_hidden_field_value', 'wpmudev_populate_hidden_field_date', 10, 4);

function wpmudev_populate_hidden_field_date($value, $saved_value, $field, $hidden_field)
{

    if ('custom_value' == $saved_value && '{custom_day_value}' == $value) {
        //get a current day of the month
        $date = strtotime(date("m/dY"));

        // Check if the current day is less than 6th day of the month
        if (date("d", $date) <= 6) {
            $prepared_data['hidden-1'] = 35; // change the value of hidden field
        } else {
            $prepared_data['hidden-1'] = 40; // change the value of hidden field
        }
    }

    return $value;
}

Replace the form ID where it says “Please change the form ID”,

Update the “hidden-1” in the code in case it is a different hidden ID.

Now it will add the 40 or 35 as a value for the hidden field dynamically depending on the day.

Hi @salgraphics

We haven’t heard from you in a while, I’ll go and mark this thread as resolved. If you have any additional questions or require further help, please let us know!

Kind Regards,

Hi Kris, I have not seen your answers !!! I really appreciate your help here.

This is a great solution, I’ll apply it right now. I have been doing it via Jscript and CSS hiding / showing the CSS class.

Let me try this one and I’ll share the results

Thanks!
