How to Solve "Trying to get property of non-object" in Laravel?

Question

If my code return null then it generates this error. If the code returns some data, then it works fine.

Controller

$profile_data= DB::table('partner_prefence')
    ->select('*')
    ->where('profile_id',$profile_id)
    ->first();

return view('partner_prefence',['profile_data' =>  $profile_data]);

View/Blade

@php($rel_status = explode(',', $profile_data->p_marital_status))

If $profile->p_marital_status has a value then there's no issue. The error only comes when its value is null.

Answer 1

Depending on whether the entry is vital for the page to be rendered or not, you could either perform a check in the controller.

$profile_data = DB::table('partner_prefence')
->select('*')
->where('profile_id',$profile_id)
->firstOrFail()

Or allow the null value to pass on to the view and make a ternary check.

$profile_data ? $profile_data->p_marital_status : '';

Answer 2

Simply use an isset() or != null on the sentence like this:

@php($rel_status = $profile_data ? explode(',', $profile_data->p_marital_status?: '')) : [];

Answer 3

First $profile_data need to be checked whether it is empty or it has some data. step2: Checking $profile_data object has property called p_material_status. Step3: If the above both are true then try to explode the data otherwise return some error message and try not explode the data would be better.

<?php

$data = (($profile_data != null) && property_exists($profile_data->p_marital_status)) ? $profile_data->p_marital_status : null)
if($data){
$rel_status = explode(',', $data);
}else{
    // Something else
}

?>

Answer 4

Use optional() https://laravel.com/docs/5.8/helpers#method-optional

If the given object is null, properties and methods will return null instead of causing an error.

{!! old('name', optional($user)->name) !!}
