I am new to twig and struggling with the following scenario.

I have a select for country names (United Kingdom & Republic of Ireland) and I'm struggling when the twig variable value returned does not match a value in the select.

I have it working if the variable is empty but need help with the above.#

This is my full select HTML (I have removed all the twig code to make it clear)

<select id="compAddCountryDd" name="compAddCountryDd" >
    <option value='' >Please Select</option>
    <option value="United Kingdom">United Kingdom</option>
    <option value="Republic of Ireland">Republic of Ireland</option>
</select>

This is the code I have for my 'Please Select' option if empty, which I have working

{% if companyDetails is defined and companyDetails.address.country == '' %}
    <option value='' 
            selected style="display: none" disabled>
        Please Select
    </option>
{% endif %}

But I cant seem to get it to display if the variable is defined but does not match the values in the select.

This I have tried the following code for the twig if

{% if companyDetails is defined and companyDetails.address.country == '' and
      companyDetails.address.country != 'United Kingdom' and
      companyDetails.address.country != 'Republic of Ireland' %}

and also

{% if companyDetails is defined and companyDetails.address.country == '' or
      companyDetails.address.country != 'United Kingdom' or
      companyDetails.address.country != 'Republic of Ireland' %}

Basically, I need my 'Please Select' option to be displayed if it:

1. Is defined
2. Does not equal 'United Kingdom'
3. Does not equal 'Republic of Ireland'

You are missing some parentheses here to comply to your logic:

• You want to the variable to be defined
• AND
• The country is either empty OR not equal to the UK AND not equal to Ireland

{% if companyDetails|default and (companyDetails.address.country|trim == '' or companyDetails.address.country != 'United Kingdom' and companyDetails.address.country != 'Republic of Ireland') %}
    Show
{% else %}
    Don't show
{% endif %}

I would however rewrite this to the following:

{% if companyDetails|default and (companyDetails.address.country|trim == '' or companyDetails.address.country not in [ 'United Kingdom', 'Republic of Ireland' ]) %}
    Show
{% else %}
    Don't show
{% endif %}
