Create Field from API and give read-access only to superusers

[markus_blue_tomato]

I want to create a field, which I add later to a template.

How can I set the access-rights only to superusers? I want, that this field is only visible to superusers.
And my second question: Is it possible to make the field also read-only in the frontend but write-able from the API?

$field = new Field();
$field->type = $modules->get("FieldtypeText");
$field->name = "my_field";
$field->label = "My Field Label";
$field->value = '';
$field->save();

Both are possible:

Sorry to not bring more info right now, don't really know how to set it through the API, but surely there is a way.

I have just added access rights to TracyDebugger's RequestInfo > Field Code section.

It now contains:

[
    'type' => 'FieldtypeText',
    'flags' => '32800',
    'name' => 'my_field_2',
    'label' => 'My Field 2 Label',
    'collapsed' => '0',
    'minlength' => '0',
    'maxlength' => '2048',
    'showCount' => '0',
    'size' => '0',
    'tags' => '',
    'editRoles' => [
        'editor',
    ],
    'viewRoles' => [
        'author',
        'editor',
    ],
    'textformatters' => '',
    'showIf' => '',
    'themeInputSize' => '',
    'themeInputWidth' => '',
    'themeOffset' => '',
    'themeBorder' => '',
    'themeColor' => '',
    'themeBlank' => '',
    'columnWidth' => '100',
    'required' => '',
    'requiredAttr' => '',
    'requiredIf' => '',
    'stripTags' => '',
    'placeholder' => '',
    'pattern' => '',
]

which is everything to need to create a field via the API including the view and edit restrictions.

You can then simply wrap this output in:

$f = new Field();
foreach()
$f->save();

so that you have:

$f = new Field();
foreach([
    'type' => 'FieldtypeText',
    'flags' => '32800',
    'name' => 'my_field',
    'label' => 'My Field Label',
    'collapsed' => '0',
    'minlength' => '0',
    'maxlength' => '2048',
    'showCount' => '0',
    'size' => '0',
    'tags' => '',
    'editRoles' => [
        'editor',
    ],
    'viewRoles' => [
        'author',
        'editor',
    ],
    'textformatters' => '',
    'showIf' => '',
    'themeInputSize' => '',
    'themeInputWidth' => '',
    'themeOffset' => '',
    'themeBorder' => '',
    'themeColor' => '',
    'themeBlank' => '',
    'columnWidth' => '100',
    'required' => '',
    'requiredAttr' => '',
    'requiredIf' => '',
    'stripTags' => '',
    'placeholder' => '',
    'pattern' => '',
] as $k => $v) {
    $f->$k = $v;
}
$f->save();

So to get this to work, create a field via the PW admin and set it up exactly how you want with the access restrictions, then go to the RequestInfo panel and copy the array from the "Field Code" section. Note that this section is not turned on by default when you install Tracy, so you will need to go to the config settings for the RequestInfo panel and turn it on.

@tiefenbacher_bluetomato - Just a quick note to say that I just pushed another revised version that fixes a bug in the previous one, so please be sure to update if you want to use this feature.

Thanks!

I tried this and it works great (example):

$field->useRoles = 1;
$field->editRoles = array('author');
$field->viewRoles = array('translator', 'author');

But I decided to solve it in an other way - because I have an hook where "translator" have also edit right to the field. The user only should not have write-access in the GUI to it.

I solved this with the "Visibility" setting. Namend "collapsed in the API:

$field->collapsed = 7;

That's exactly why I built it - thanks for improving it further @adrian ?

Just a quick tip you might find helpful. It makes the code more readable if you use constants instead of integer variables. You'll get them from intellisense in your IDE so it's also easier to look them up like this than heading over to the docs:
