如何在数据库Laravel中联接两个表

Question

I'm trying to join two tables (products table and Images table), so in products table each product has multiple images(stored in a row named image) so I want to display images of each product in images table . In images table I have a foreign key named product_id references(id) on products table, The problem is it can't store images in images table,(it keeps storing images in the row(image) in products table). How do I solve this?

Codes

Product.php

public function images()
 {
   return $this->hasMany('App\Image', 'product_id');
 }

Image.php

public function product()
{
  return $this->belongsTo('App\Product','product_id');
 }

Controller

 public function store(Request $request) 
 { 

$Input=$request->all();
$image=array();
if($files=$request->file('image')){
foreach($files as $file){
    $name=$file->getClientOriginalName();
    $file->move('images',$name);
    $image[]=$name;
  }
  } 
 product::create(array_merge($Input,
 [
 'image' => json_encode($image),

 ])); 
return redirect()->back(); 

}

Any help will be appriciated.

If you are trying to save the image to the images table, and you are instead 'it keeps storing images in the row(image) in products table' - you are saving the wrong item. You appear to have the correct structure - with one to many in your models. Just need to save the Image rather than the Product

Something like this will fix this issue:

Image::create(['whateverYouNeedToSave', 
              'product_id'=>$product_id,      <-- Connect the product here, within the image
              'etc']);

It is actually possible to do this by creating the Product and then saving the Images as a relation, but this might not be the cleanest / easiest way to architect this - suggest you start with saving the Image , as you will have many of them, vs. just one Product at a time. Then, after this works, and is clear / comfortable, you can try it the more 'advanced' way if you need to.
