GUID in querystring to use in form

use that project’s GUID in a form field to create a new record

What are you trying to set? A guid of the new record (which is usually not recommended) or a lookup field?

I am trying to set a lookup field.

Hey Joe,

lookups are EntityReference objects so the value looks like { "LogicalName": "contact", "Id": "00000000-0000-0000-0000-000000000000", "DisplayName" : "Joe" }. For example:

<input type="hidden" name="foo_project" value='{ "LogicalName": "msdyn_project", "Id": {{params.projectId}} }' />

Display name isn’t really used to set the value unless you’re setting default for the visual lookup control (that one is in premium addon).

Hi George-

Thanks for the guidance here. I’ve just been able to get back to this project again.

These are my two form fields:

{% form entity="jcma_projectvolunteer" mode="create" %}
<form>
    <div class="form-group">
        <input type="form-control" name="jcma_project" value='{ "LogicalName": "jcma_projectvolunteer", "Id": {{projectid}} }'>
    </div>
    <div class="form-group">
        <input type="form-control" name="jcma_contact" value='{ "LogicalName": "jcma_projectvolunteer", "Id": {{contactid}} }'>
    </div>
    <div class="form-group">
        <button type="submit" class="btn btn-primary">Join This Project</button>
    </div>
</form>
{% endform %}

When I load the page and look at the two fields, this is what is filled in:

Project:
{ “LogicalName”: “jcma_projectvolunteer”, “Id”: 9fee4671-5fca-ec11-a7b5-000d3a998753 }

Contact:
{ “LogicalName”: “jcma_projectvolunteer”, “Id”: 258cc37a-2dd2-ec11-a7b5-0022481ce6f7 }

When I submit, it gives me this really nasty error:
Failed to submit the form.
There has been a critical error on this website.

How can I look at some error checking or find out what is causing this to fail?

Thank you.
Joe

@josephmarkovich

the values look wrong, LogicalName should be “contact” for one and “msdyn_project” for another one.

More information is usually available in the debug log (set in plugin configuration)

Hi George-

Thanks for the help with that! That was part of it. The other part was the missing quotes around the GUID.

{ "LogicalName": "jcma_project", "Id": "9fee4671-5fca-ec11-a7b5-000d3a998753" }
{ "LogicalName": "contact", "Id": "258cc37a-2dd2-ec11-a7b5-0022481ce6f7" }

It would help if I had read the documentation closer!
{ "LogicalName": "contact", "Id": "00000000-0000-0000-0000-000000000000" }

Thank you!
Joe
