Issue with form?

[stephenmeehanuk]

Hi

Spotted this error in laravel.log

[2022-05-16 09:38:13] local.DEBUG: Cannot render an object variable as a string: {{ placeholder }}  

I figured it's related to a handle called {{ placeholder }} , but this handle isn't part of the current view template?

The error only appears when there's a form on the page. And it repeats based on the number of fields the form has.

As a test, I created this basic, one field form, resources/blueprints/forms/test.yaml

sections:
  main:
    display: Main
    fields:
      -
        handle: text_field
        field:
          input_type: text
          antlers: false
          display: 'Text Field'
          type: text
          icon: text
          listable: hidden
          instructions_position: above
          read_only: false

I add the form to my view

  {{ form:test }}

  {{ /form:test }}

If remove {{ form:test }}{{ /form:test }} the error goes away?

It's odd because the error references a handle that's not being used by the view?

As a final test I cleared everything from the layout except {{ template_content }}. Then removed everything from the view, except {{ form:test }}{{ /form:test }} then I ran php artisan optimize:clear, the error still persists?

I've tried this on a fresh install and there's no error. I'm running the same version of Statamic

Statamic 3.3.11 Pro
Laravel 9.12.2
PHP 8.0.8

Is there anything else I can try to debug this?

Hi @stephenmeehanuk,

My guess would be that the {{ placeholder }} handle comes from the default form fields. So it doesn't have to be in your template explicitly to show you that log message.

Have a look at #2354.
Form fields have a conditional display of the {{ placeholder }} handle.

<input type="text" name="{{ handle }}" {{ if placeholder }}placeholder="{{ placeholder }}"{{ /if }}{{ if old }}value="{{ old }}"{{ /if }}>

Also, Laravel uses the RFC 5424 specification for logging messages.
It has different levels that are as follow.

1. emergency
2. alert
3. critical
4. error
5. warning
6. notice
7. info
8. debug

As you can see, you got a debug message logged which is the lowest level. So there is nothing necessarily wrong.
More on that in the Laravel docs

Hope that helps!

Ah, good guess!

I created another test form, added some placeholder text and there's no error. Great... kinda.

However, I can't get the {{ if placeholder }}placeholder="{{ placeholder }}"{{ /if }} to work?

If there's no placeholder text the {{ if placeholder }} check fails to work. I feel like the {{ if placeholder }} check shouldn't be required in the first place, if there's no placeholder.

You're right, debug is the lowest bug report, but I'd rather there be no messages! :)

Got a bit further with this...

On a fresh install this works great, there's no local.DEBUG message when text_field doesn't have a placeholder

// resources/blueprints/forms/test.yaml
sections:
  main:
    display: Main
    fields:
      -
        handle: text_field
        field:
          input_type: text
          antlers: false
          display: 'Text Field'
          type: text
          icon: text
          listable: hidden
          instructions_position: above
          read_only: false

{{ form:test }}
    {{ fields where="handle:text_field" }}
        {{ placeholder }}
    {{ /fields  }}
{{ /form:test }}

But, on another install - A site I upgraded to 3.3.11,

// resources/blueprints/forms/test_form.yaml
sections:
  main:
    display: Main
    fields:
      -
        handle: text_field
        field:
          input_type: text
          antlers: false
          display: 'Text Field'
          type: text
          icon: text
          listable: hidden
          instructions_position: above
          read_only: false

{{ form:test_form }}
    {{ fields where="handle:text_field" }}
        {{ placeholder }}
    {{ /fields  }}
{{ /form:test_form }}

this generates an error

local.DEBUG: Cannot render an object variable as a string: {{ placeholder }}  

Is there a known reason why this is happening? It's worth mentioning, when placeholder exists it is shown. It just triggers a debug message when it's not there?

Both test forms only have a single text field. Both sites running locally on Valet
