Using laravel validation, I would like to ensure that a field is unique, but in an array context. (I have seen this and this but they don't address the array context.)
Let's suppose I have this html:
<input name="sites[1][id]"><input name="sites[1][site_mrn]">
<input name="sites[2][id]"><input name="sites[2][site_mrn]">
<input name="sites[3][id]"><input name="sites[3][site_mrn]">
In my validation rule, I want to ensure that each site's id is valid, and that the site_mrn is not blank, so I have:
public function rules()
{
return [
'sites.*.site_mrn' => 'required|min:1',
'sites.*.id' => 'exists:sites,id'
];
}
So that part works. My problem is that I want to ensure that each pair of site site_id and site_mrn are unique in the mpi_sites table, but I don't know how to access each id/site_mrn pair in the input. I want to do something like this:
'sites.*' => Rule::unique('mpi_sites')->where(function ($q) {
$q->where('site_id', $xxxxx)->where('site_mrn', $yyyyy);
})
