Form Pricing Details

Pricing Features table

Answer 1

For that, you should use a relationship One to Many :https://laravel.com/docs/9.x/eloquent-relationships#one-to-many

Logic example:

<?php
 
namespace App\Models;
 
use Illuminate\Database\Eloquent\Model;
 
class PricingDetail extends Model
{
    /**
     * Get the features for the pricing detail.
     */
    public function features()
    {
        return $this->hasMany(PricingFeature::class);
    }
}

foreach($request->pricing_title as $key=>$value){
    $pricing = new PricingDetail;
    $pricing->software_id=$software->id;
    $pricing->pricing_title=$request->pricing_title[$key];
    $pricing->pricing_amount=$request->pricing_amount[$key];
    $pricing->pricing_terms=$request->pricing_terms[$key];
    $pricing->save();

    // Changes
    $pricing->features()->save($request->pricing_features);
}

Answer 2

You don't do any json_encode or something. Just cast the field you wanted to save as array in your model class as below.

PricingFeature.php

protected $casts = [
    'pricing_features'               => 'array',
];

And then you can go ahead with your following code.

foreach($request->pricing_title as $key=>$value){
            $pricing = new PricingDetail;
            $pricing->software_id=$software->id;
            $pricing->pricing_title=$request->pricing_title[$key];
            $pricing->pricing_amount=$request->pricing_amount[$key];
            $pricing->pricing_terms=$request->pricing_terms[$key];
            $pricing->save();
            foreach($request->pricing_title as $pt){
                $pricingfeatures = new PricingFeature;
                $pricingfeatures->pricing_details_id=$pricing->id;
                $pricingfeatures->pricing_features=$request->pricing_features;
                $pricingfeatures->save();
            }
        }
