Dynamic display by Twig

[Kevin]

Hello to all,

I try to show/hide some field depending on service selected.
I tried those codes :

<div class="col-sm-6">
    {% if service_id != 18 %}
        <div class="form_field" data-field-id="product_impacted" data-field-flags="mandatory"></div>
    {% else %}
        <div class="form_field" data-field-id="uct_product_impacted" data-field-flags="mandatory"></div>
        {% endif %}
</div>

and

<div class="col-sm-6">
    {% if service_id != "Unified Connect" %}
        <div class="form_field" data-field-id="product_impacted" data-field-flags="mandatory"></div>
    {% else %}
        <div class="form_field" data-field-id="uct_product_impacted" data-field-flags="mandatory"></div>
    {% endif %}
</div>

But the 1st field is always displayed...

Could it be possible to check another field value in the twig ?

Kind regards,

service_id would probably indeed be a number, but I'm not sure you can directly access the attribute value that way?

Thanks for your answer.
Yes, that's why I tried "if service_id != 18" but the if is always "true"...
I will wait if someone else know if it is possible or not :)

I bypassed the problem :p
I created a new class Product and the field in ticket is a SELECT query based on the Service ID :)

Hello Kevin, if you want to achieve this you shouldn't do it in the TWIG directly, but in the object GetInitialAttributeFlags() method.

The idea is to:
- In the datamodel define the dependancy between 2 fields
- In the GetInitialAttribuetFlags() method, set the flag to hidden depending on the value of the other attribute

Hope thie helps,
Guillaume
