Liquid If/Else problem

Oliver Knigge

Hi,

I have found a similar post here:
https://support.zendesk.com/hc/en-us/community/posts/208931908-LIquid-if-else-not-working

I have a problem to get some liquid expressions in triggers running correctly. I have several triggers, which informs a user about a new comment in a ticket. We are using different triggers for different ticket groups and basically this works. 

But we have agents of the same group in different locations. In the e-mail notification, I want the user to know, from where he was getting the answer. 

For this I have tried an if-expression with Liquid, which is not working.
What makes me really confusing is that another if-expression in the same trigger is working without problems. 

The first if-expression, which is already working does only differentiate a specific agent:

{% if current_user.id == 123456789 %}
Ms. {{current_user}}
{% else %}
{{current_user}}
{% endif %}

Later on in the trigger, I have the next if-expression, which is not working and I do not know why.

{% if ticket,group.name == 'Group A' or 'Group B' %}
Office Potsdam<br />Abt. RMA<br />
{% else %}
Office Sarstedt<br />Abt. RMA<br /> 
{% endif %}

The output of this if-expression seems to be always true. It doesn't matter to which ticket.group the ticket is assigned, it gives me always the output like true:

Office Potsdam<br />Abt. RMA<br /> 

This is really confusing. In another trigger I have a if-expression, which decides also by group, if a satisfaction.rating will be send out to the customer and this is working:

{% if ticket.group.name == 'Group A' or 'Group B' or 'Group C' %}
 {{satisfaction.rating_section}}
{% endif %}

The difference is, that I do not have an {% else %} tag in this expression.

I have other triggers with the same problem, where the if-expression will be always true, no matter whicht metrics the ticket really have.

Does anybody have the same issues or a tip/workaround to solve this?

Thanks in advance!

    Hi Oliver!

    I am by no means a Liquid expert, but I'm wondering if the 'Group A' or 'Group B' condition might be the problem. Is an OR condition generally supported in Liquid? 

    We have a couple Community Moderators who are good with Liquid so I'm going to track them down and ask them to weigh in on this! Sit tight!

    Hi Jessie,

    thank you very much.

    "The available Boolean operators are:

    • and
    • or"

    (source: https://github.com/Shopify/liquid/wiki/Liquid-for-Designers)

    It is really confusing. I have if-expressions in multiple triggers, sometimes they work correctly, sometimes the expression is always true (even if it should be false). 

    And I have tried so many versions like

    {% if ticket.group.name == 'Group A' or ticket.group.name == 'Group B' or ticket.group.name == 'Group C' %}

    This also doesn't work. Don't know what is happening exactly.

    I have solved the problem for now with creating more triggers. I have the conditions, which are not working with Liquid in the trigger now. 

    But I see the next problem is occuring...

    If-expressions with the "ticket.tags" attribute seems to be also not working.
    The following example won't work:

    {% for comment in ticket.comments %}
    {% if ticket.tags contains 'tag_1' or 'tag_2' and forloop.last == 'true' %}
    End
    {% else %}
    {{comment.value}}
    {% endif %}
    {% endfor %}

    With this expressions, I would like to have a comment history in the e-mail notification. 
    When having specific tags in the ticket, I do not want to show the earliest (first) comment (=submit) in the ticket history, only the word "End".

    As explained above, the if-expression with the ticket.tag attribute is always true and I'm getting always "End", even the ticket does not have such tags or it is not the last forloop.

    I have also tried

    {% assign tags = ticket.tags | split: " " %}

    and then using the tags-variable in the if-expression - same result, always true.

    This is strange :)

    Now I have tried it with nested if-expression - again not working :(

    {% for comment in ticket.comments offset:1 %}
    {% if forloop.last == true %}{% if ticket.tags contains 'tag_1' or 'tag_2' %}{% break %}{% endif %}{% endif %}
    {{comment.value}}
    {% endfor %}

    But here the output is always the {{comment.value}} even it is the last loop and the ticket.tags contains 'tag_1' or 'tag_2' - But here it should completely end the forloop ("break") - it does not work :(

    I absolutely don't know how this is happening.

    Just to be up to date:

    Now I have found out, that the if-expression with the "forloop.last" attribute is working.

    {% for comment in ticket.comments offset:1 %}
    {% if forloop.last == true %}{% break %}{% endif %}
    {{comment.value}}
    {% endfor %}

    This puts me out the comment history without the first ticket comment/submitting description (last forloop). 

    So I need a solution for the ticket.tags. I have found a workaround here:

    https://support.zendesk.com/hc/en-us/community/posts/203413686-Using-zendesk-tags-in-liquid-markup

    But I do not understand the liquid {% capture %} tag exactly. Can anyone help?

    Hey Oliver!

    I haven't had a chance to actually learn Liquid yet, so I'm afraid I can't be of any help. But I have brought this to the attention of our awesome Community Moderators, so hopefully they'll be able to give you some insight!

    Hi, thanks again! :)

    And no problem, I have posted a lot and I can totally understand, that you do not have a tip on each comment :)
    Liquid is a really complex language.

    I just want you or the moderators to be up to date with what I'm doing.That's why I'm posting every step I've tried.

    Maybe I get some help over here too:

    I am in cheerful spirits that we get this solved :)
    For now, I wish you a pleasent and sunny weekend!

    Hi There!

    I don't know if this is the right topic for me to write my concern.

    I'm trying to make a trigger that will notify specific email user for every update of a ticket.

    I just can't find a proper placeholder for my condition.

    here's the logic:

    if a ticket update has a comment either public or internal

    then {{ticket.comments_formatted}}

    else {'predefined text'}

    Hi Donald Cornel I can't find a placeholder that would do what I think you are wanting to do. You can use liquid markup to create dynamic content, but that content has to be based on something in Zendesk (like business hours or a ticket field) rather than a freestanding text block I believe. There's are quite a few examples linked in the Liquid Markup article.
