Your action should look like this:

use Illuminate\Http\Request;

public function deletepost(Request $request) // add Request to get the post data
{
    $tagId = $request->input('id'); // here you define $tagId by the post data you send
    $post = post::find($tagId);
    if ($post) {
        $post->delete();
        echo ('record is deleted!');
    } else {
        echo 'record not found!');
    }
}

public function deletepost(Request $request) { $tagId = $request->input('tag'); $post = post::find($tagId); $post->delete($tagId ); echo ('record is deleted') ; } by changing this followinf error came Call to a member function delete() on null

And change $tagId = $request->input('id');, the id to the name of the post id identifier sent by the post request.

i think in 5.3 we have to use get method instead of input. but your logic worked. Thanks and if we want to delete any record on the custom bases , other than primary key we have to specify our condition.

Actually I was playing around with Laravel since 5.4, but I'm glad you've found the solution.

You have to pass the parameter for an example if you pass it like tag_id then you have to capture it inside the controller function using Request.

public function deletepost(Request $request){

   $post = post::find($request::get('tag_id')); 
   $post->delete();
   echo ('record is deleted');
}

You are not telling the route to expect that parameter. You should try it this way in your routes file:

Route::get('/delete/{tag}' , array('as' =>'delete' , 'uses' => 'Postcontroller@deletepost'));
