remove required from passenger select dropdown when rider-with-pillion-passenger-2 not selected

Assistant
You can modify your jQuery script to remove the `required` attribute from the passenger-related select fields when `rider-with-pillion-passenger-2` is not selected and add it back when it is selected. Here's the updated code:

jQuery(".addon_fn_booking_type select").change(function () {
    var fieldVal = jQuery(this).val();

    if (fieldVal == 'room-share-3') {
        jQuery('.addon_fn_room_share_name').show();
    } else {
        jQuery('.addon_fn_room_share_name').hide();
    }

    if (fieldVal == 'rider-with-pillion-passenger-2') {
        jQuery('.addon_fn_passenger_jacket, .addon_fn_passenger_gloves, .addon_fn_passenger_jet_helmet').show();
        jQuery('.addon_fn_passenger_jacket select, .addon_fn_passenger_gloves select, .addon_fn_passenger_jet_helmet select').attr('required', 'required');
    } else {
        jQuery('.addon_fn_passenger_jacket, .addon_fn_passenger_gloves, .addon_fn_passenger_jet_helmet').hide();
        jQuery('.addon_fn_passenger_jacket select, .addon_fn_passenger_gloves select, .addon_fn_passenger_jet_helmet select').removeAttr('required');
    }
});

### Explanation:
– If `rider-with-pillion-passenger-2` is selected:
– Show the passenger-related fields.
– Add the `required` attribute to the corresponding “ elements.
– If any other option is selected:
– Hide the passenger-related fields.
– Remove the `required` attribute from the corresponding “ elements.

this is a woocommerce add-on varient

Since WooCommerce's Product Add-Ons use `data-restrictions` attributes along with the `required` attribute, simply using `.removeAttr('required')` might not be enough. You'll also need to modify the `data-restrictions` attribute to remove the `"required":"yes"` part dynamically.

### **Updated jQuery Code:**

jQuery(".addon_fn_booking_type select").change(function () {
    var fieldVal = jQuery(this).val();
    
    // Room share visibility toggle
    if (fieldVal == 'room-share-3') {
        jQuery('.addon_fn_room_share_name').show();
    } else {
        jQuery('.addon_fn_room_share_name').hide();
    }

    // Passenger fields visibility and required attribute toggle
    var passengerFields = jQuery('.addon_fn_passenger_jacket, .addon_fn_passenger_gloves, .addon_fn_passenger_jet_helmet');
    var passengerSelects = passengerFields.find("select");

    if (fieldVal == 'rider-with-pillion-passenger-2') {
        passengerFields.show();
        passengerSelects.attr('required', 'required');

        // Update data-restrictions attribute
        passengerSelects.each(function () {
            var restrictions = jQuery(this).data('restrictions');
            if (restrictions) {
                restrictions.required = "yes";
                jQuery(this).attr('data-restrictions', JSON.stringify(restrictions));
            }
        });
    } else {
        passengerFields.hide();
        passengerSelects.removeAttr('required');

        // Update data-restrictions attribute
        passengerSelects.each(function () {
            var restrictions = jQuery(this).data('restrictions');
            if (restrictions) {
                delete restrictions.required;
                jQuery(this).attr('data-restrictions', JSON.stringify(restrictions));
            }
        });
    }
});

### **What This Does:**
✔ **Hides/Shows fields** based on selection.
✔ **Adds/Removes `required`** attribute from passenger select fields.
✔ **Updates `data-restrictions` attribute**, removing `"required":"yes"` dynamically.

This ensures WooCommerce's validation system correctly recognizes whether the field is required or not.

i think its works when in page but when click on add to cart then its give required error
Assistant
WooCommerce's validation system still considers the `required` attribute stored in `data-restrictions`. When you dynamically remove `required`, WooCommerce might still check the `data-restrictions` value during validation.

To fully bypass WooCommerce’s required validation, we need to handle it **before adding the product to the cart** by modifying the data attribute and ensuring WooCommerce doesn’t enforce validation.

### **Final jQuery Solution:**

jQuery(document).ready(function () {
    jQuery(".addon_fn_booking_type select").change(function () {
        var fieldVal = jQuery(this).val();

        // Room share visibility toggle
        if (fieldVal == 'room-share-3') {
            jQuery('.addon_fn_room_share_name').show();
        } else {
            jQuery('.addon_fn_room_share_name').hide();
        }

        // Passenger fields and validation handling
        var passengerFields = jQuery('.addon_fn_passenger_jacket, .addon_fn_passenger_gloves, .addon_fn_passenger_jet_helmet');
        var passengerSelects = passengerFields.find("select");

        if (fieldVal == 'rider-with-pillion-passenger-2') {
            passengerFields.show();
            passengerSelects.prop('required', true).each(function () {
                var restrictions = jQuery(this).data('restrictions') || {};
                restrictions.required = "yes";
                jQuery(this).attr('data-restrictions', JSON.stringify(restrictions));
            });
        } else {
            passengerFields.hide();
            passengerSelects.prop('required', false).each(function () {
                var restrictions = jQuery(this).data('restrictions') || {};
                delete restrictions.required;
                jQuery(this).attr('data-restrictions', JSON.stringify(restrictions));
            });
        }
    });

    // Prevent WooCommerce validation error before adding to cart
    jQuery("form.cart").on("submit", function (e) {
        var fieldVal = jQuery(".addon_fn_booking_type select").val();
        
        if (fieldVal !== 'rider-with-pillion-passenger-2') {
            jQuery('.addon_fn_passenger_jacket select, .addon_fn_passenger_gloves select, .addon_fn_passenger_jet_helmet select').each(function () {
                jQuery(this).prop('required', false);
                var restrictions = jQuery(this).data('restrictions') || {};
                delete restrictions.required;
                jQuery(this).attr('data-restrictions', JSON.stringify(restrictions));
            });
        }
    });
});

### **What This Fix Does:**
1. **Handles visibility** of passenger-related fields.
2. **Modifies `required` dynamically** when the option changes.
3. **Ensures WooCommerce does not enforce validation** before adding to the cart by adjusting `data-restrictions`.

—

### **Why This Works:**
– When clicking "Add to Cart", WooCommerce checks **both** the `required` attribute and `data-restrictions`.
– By modifying them just before submission, WooCommerce skips validation for hidden fields.

This should now prevent the required error when clicking "Add to Cart"! 🚀 Let me know if you need further adjustments. 😊

its referesh page when click on add to cart

Since WooCommerce's Add to Cart button triggers a full page refresh by default, you'll need to **ensure JavaScript properly prevents form validation errors and allows AJAX add-to-cart functionality**.

### **Improved jQuery Solution with AJAX Support**

jQuery(document).ready(function () {
    function togglePassengerFields(fieldVal) {
        var passengerFields = jQuery('.addon_fn_passenger_jacket, .addon_fn_passenger_gloves, .addon_fn_passenger_jet_helmet');
        var passengerSelects = passengerFields.find("select");

        if (fieldVal === 'rider-with-pillion-passenger-2') {
            passengerFields.show();
            passengerSelects.prop('required', true).each(function () {
                var restrictions = jQuery(this).data('restrictions') || {};
                restrictions.required = "yes";
                jQuery(this).attr('data-restrictions', JSON.stringify(restrictions));
            });
        } else {
            passengerFields.hide();
            passengerSelects.prop('required', false).each(function () {
                var restrictions = jQuery(this).data('restrictions') || {};
                delete restrictions.required;
                jQuery(this).attr('data-restrictions', JSON.stringify(restrictions));
            });
        }
    }

    // Run function on change event
    jQuery(".addon_fn_booking_type select").change(function () {
        togglePassengerFields(jQuery(this).val());
    });

    // Ensure WooCommerce validation does not interfere
    jQuery("form.cart").on("submit", function (e) {
        var fieldVal = jQuery(".addon_fn_booking_type select").val();

        if (fieldVal !== 'rider-with-pillion-passenger-2') {
            jQuery('.addon_fn_passenger_jacket select, .addon_fn_passenger_gloves select, .addon_fn_passenger_jet_helmet select').each(function () {
                jQuery(this).prop('required', false);
                var restrictions = jQuery(this).data('restrictions') || {};
                delete restrictions.required;
                jQuery(this).attr('data-restrictions', JSON.stringify(restrictions));
            });
        }
    });

    // Enable AJAX Add to Cart if applicable
    jQuery(document).on("click", ".single_add_to_cart_button", function (e) {
        e.preventDefault(); // Prevent full page refresh

        var form = jQuery(this).closest("form.cart");
        var formData = form.serialize(); // Get all form data

        jQuery.post(form.attr("action"), formData, function (response) {
            // If WooCommerce AJAX is enabled, handle response
            if (typeof wc_add_to_cart_params !== "undefined") {
                jQuery(document.body).trigger("added_to_cart", [response.fragments, response.cart_hash, jQuery(this)]);
            } else {
                window.location.href = wc_add_to_cart_params.cart_url; // Fallback to cart page
            }
        });
    });
});

### **Fixes & Improvements:**
1. ✅ **Dynamically hides/shows fields and updates `required` attributes**.
2. ✅ **Prevents WooCommerce validation from interfering** when hidden fields exist.
3. ✅ **Uses AJAX for "Add to Cart" to prevent full-page refresh** (if WooCommerce AJAX is enabled).
4. ✅ **Ensures form submission works even if AJAX is disabled** (fallback to cart page).

Now, your WooCommerce Add-Ons variant should work seamlessly without a page refresh while properly validating required fields. 🚀 Let me know if you need further refinements! 😊

If WooCommerce is still refreshing the page when clicking "Add to Cart," we need to focus on **three key fixes**:

1. **Ensuring the `required` attribute is properly removed from hidden fields.**
2. **Preventing WooCommerce from enforcing validation on hidden fields.**
3. **Forcing WooCommerce's AJAX add-to-cart functionality to work correctly.**

### **What This Fix Does:**
✅ **Removes the `required` attribute** dynamically when the hidden fields are not needed.
✅ **Ensures WooCommerce ignores `data-restrictions`** validation by modifying its JSON structure.
✅ **Prevents the full-page reload** by enforcing AJAX-based "Add to Cart."

This will ensure WooCommerce does not enforce required fields when they are hidden. 🚀
