Save multi-level array using Laravel Model - php

Question

I have problem to save this data using Laravel-7 model
this is my data
$supplier = [
'name' => 'Supplier 1',
'pic' => [
[
'name' => 'PIC 1',
'phone_number' => [
['number' => '111111'],
['number' => '123456']
]
],
[
'name' => 'PIC 2',
'phone_number' => [
['number' => '222222']
]
]
]
];
And this is my models
Supplier.php
// Supplier.php
public function supplier_pic()
{
return $this->hasMany('SupplierPIC');
}
and the other models
// SupplierPIC.php
public function supplier()
{
return $this->belongsTo('Supplier');
}
public function pic_phone_number()
{
return $this->hasMany('SupplierPICPhoneNumber');
}
// SupplierPICPhoneNumber.php
public function supplier_pic()
{
return $this->belongsTo('SupplierPIC');
}
How to save those data on controller ?
Thank you

You just need to break it down into it's constituent objects.
In your case, it is one Supplier object with two SupplierPIC objects, each of which has a SupplierPICPhoneNumber
Create Supplier
$supplier = Supplier::firstOrCreate([
'name' => 'Supplier 1'
]);
Create Supplier PIC(s)
collect($data['pics'])->each(function ($pic) use ($supplier) {
// Create the PIC
$x = SupplierPIC::create([
'name' => $pic['name']
]);
// Attach it to the supplier
$supplier->supplier_pic()->save($x);
// Attach phone numbers
collect($pic['phone_number'])->each(function ($number) use ($x) {
// Create the PIC Phone number
$y = SupplierPICPhoneNumber::create([
'number' => $pic['number']
]);
// Attach the number to the PIC
$x->pic_phone_number()->save($y);
});
});
Suggestions
The naming of your relationships doesn't follow best practice which is a little confusing. Try naming things that are use a hasMany type relationship with a plural (i.e. pic_phone_numbers rather than pic_phone_number)
Do you need an entire model for SupplierPICPhoneNumber? A json column may be better suited.
