Laravel check variable passed from controller if not empty in view

Question

I have a variable passed from my controller to my view. And I want to do a check in my view if the variable is empty I show a message if it's not empty I show a div.

This is what I've tried but it gives me a syntax error:

@if(!empty({!! $json !!}))
  <div class=""></div>
@else
  <p>Empty.</p>
@endif

I've also tried

@if(!empty($json))

Doesn't work either. I can't get to see the empty message

Anyone knows what I am doing wrong here?

Many thanks in advance!

Do dd($json) and see what the value actually is.

What type are your variable? String?

Try

@if( !empty( json_decode( $json) ) )

I don't think it does really, you just had invalid syntax. You shouldn't use {!! $json !!} because as soon as you use @if() everything is in PHP and PHP doesn't know how to parse {!! !!}. All you really needed to do is remove those.

All you need is to:

<?php $json = json_decode($json, true) ?>

somewhere before @if because you gets string "[]" not array so you need to parse json to be array. Best place is to do it in the controller.

You also don't need to escape it inside @if statement:

@if(!empty($json))

Try this:

@if(count($json) > 0)
  <div class=""></div>
@else
  <p>Empty.</p>
@endif
