Insert multiple rows value to database using dynamic form in Laravel

Don't use this:

<input type="text" name="rows[][link]" value="521"> 

<input type="text" name="rows[][store]" value="542">

This will generate $rows like following:

[ 

  0 => ["link" => "foo"], 

  1 => ["store" => "bar"] 

]

But your PHP code expects $rows to be like because you want to pass 4 value:

[ 

  0 => [ "link" => "foo", 

       "store" => "bar" 

     ], 

  1 => [ "link" => "foo", 

         "store" => "bar"

     ] 

]

One way to generate the expected values is to specify the row keys in your elements:

<input type="text" name="rows[0][link]" value="123"> 

<input type="text" name="rows[0][store]" value="456"> 

<input type="text" name="rows[1][link]" value="789"> 

<input type="text" name="rows[1][store]" value="963">
