Call to a member function toArray() on array - php

Question

I’m trying to use this package: https://packagist.org/packages/digital-creative/conditional-container. However with this basic example:
return array_merge(
[
Select::make('Option', 'option')
->options([
1 => 'Option 1',
2 => 'Option 2',
3 => 'Option 3',
]),
/**
* Only show field Text::make('Field A') if the value of option is equals 1
*/
ConditionalContainer::make([ Text::make('Field A') ])->if('option = 1'),
Text::make('Title'),
Textarea::make('Description'),
],
$arr
);
I’m getting the error message: Call to a member function toArray() on array.
If I change to:
return array_merge(
[
[
Select::make('Option', 'option')
->options([
1 => 'Option 1',
2 => 'Option 2',
3 => 'Option 3',
]),
ConditionalContainer::make([ Text::make('Field A') ])->if('option = 1')
],
It shows:
message: "Call to a member function getUpdateRules() on array"
even with only the example like below it shows "message: "Call to a member function toArray() on array":
public function definition(): array
{
return [
Select::make('Option', 'option')
->options([
1 => 'Option 1',
2 => 'Option 2',
3 => 'Option 3',
]),
ConditionalContainer::make([ Text::make('Field A') ])->if('option = 1')
];
}
Do you know how to solve the issue? Thanks!

Not sure what is does, but you are sending an array to a class that class has a method toArray().
that's why i always use return types in my code cause it will break if the input does not match.
Could it be that it thinks that this is a collection or a class that needs to be inputted.
in some cases i am lazy and will try the following:
collect(return array_merge(
[
[
Select::make('Option', 'option')
->options([
1 => 'Option 1',
2 => 'Option 2',
3 => 'Option 3',
]),
ConditionalContainer::make([ Text::make('Field A') ])->if('option = 1')
],)
because many packages uses Collection as a way to handle, filter and search an array.
but this is more a guess than actuall knowledge. Look at the function getUpdateRules() in the vendor map, what does it do.
/**
* #param Resource|Model $resource
*
* #return array
*/
public function resolveDependencyFieldUsingResource($resource): array
{
$matched = $this->runConditions(
$this->flattenRelationships($resource)
);
return $matched ? $this->fields->toArray() : [];
}
this is the function so as you can see it expects a model or resource class
according to the docs:
return [
Select::make('Option', 'option')
->options([
1 => 'Option 1',
2 => 'Option 2',
3 => 'Option 3',
]),
//more suff
your return array
array_merge(
[ // <--- note the extra bracket
[
Select::make('Option', 'option')
->options([
1 => 'Option 1',
2 => 'Option 2',
3 => 'Option 3',
]),
ConditionalContainer::make([ Text::make('Field A') ])->if('option = 1')
],
