Have you tried to remove .lazy ?

Unchecking Checkbox returns false?
This is one confusing me!
I have a form with a foreach looping over positions creating input checkboxes for each position. The checked boxes go into an array.
<input wire:ignore.self class="form-check-input" type="checkbox" value="{{ $position->id }}" name="selectedPositions" wire:model.lazy="selectedPositions.{{ $position->id }}" />
Everything works fine, except when I uncheck one, that is to say I accidentally checked the wrong one, it stays in the array but has a value of "false".
^ array:4 [▼
1 => "1"
2 => false
3 => "3"
7 => "7"
]
This throws an error on the save with an Integrity constraint violation on the "false".
$group->positions()->sync($this->selectedPositions);
How can I either, 1 - get around the error, or 2 - get the checked box removed from the array when I actually uncheck it?
Thanks for the help!

@dmhall0 What about
$group->positions()->sync(array_filter($this->selectedPositions));
Also here is a similar solution

I believe the wire:model value should be
<input wire:ignore.self class="form-check-input" type="checkbox" value="{{ $position->id }}" name="selectedPositions" wire:model.lazy="selectedPositions" />

@dmhall0 what is it expected to return besides 0 or false?

@jlrdw Ideally the 2 => false would be completely removed from the array. Leaving it there is now causing an issue with my validation.

Okay, so that solution got me able to save the connected positions to the group, but I also need to validate that at least one position is checked. With the "false" return still in the array, it is not working. Here is my validation now
'selectedPositions' => ['required','integer','min:1'],
Any ideas?

@dmhall0, livewire has a method that will run prior to validation...
public function prepareForValidation($attributes)
{
$this->selectedPositions = array_filter($this->selectedPositions);
return $attributes;
}
