htmlSpecialchars() errors

@neeraj1005 it should be in this code I believe:

@php 
{{
    $first_char = mb_substr($user->name, 0, 1);
    $first_char_Capital = strtoupper($first_char);
    echo $first_char_Capital;
}}
@endphp 

So use this instead:

@php 
$first_char = mb_substr($user->name, 0, 1);
$first_char_Capital = strtoupper($first_char);                              
@endphp 

{{ $first_char_Capital }}

@nakov same error comes out

Facade\Ignition\Exceptions\ViewException
htmlspecialchars() expects parameter 1 to be string, object given (View: C:\wamp64\www\cms\resources\views\admin\userList\userList.blade.php)

@neeraj1005 can you show full code please?

Essentially what you are doing wrong is, you are using methods in between {{ }} which is the blade syntax for echoing a string.

So remove all initializations from {{ }} and use @php @endphp for that, or just do all of that in the controller and pass a variable to the view.

@neeraj1005 so you haven't changed anything that I've said..

@php 
 {{
 $first_letter = mb_substr($user->name, 0, 1);
$first_letter_Capital = strtoupper($first_letter);
 echo $first_letter_Capital;
}}
@endphp 

throws the error.

@nakov I have changed code. Then I undo this file and paste it here.

@neeraj1005 can you remove that code then, and check if the file will load on the view?

I changed this into this, and same error comes.

                    <td>
                            @if($user->picture!='profile.png')
                            <img src="{{url($user->picture) }}" class="rounded mr-2" alt="User Image" style="width: 50px; height: 50px" /> 
                            @else
                            <span class="medium-badge mr-2">
                              @php 
                              {{
                                $first_letter = mb_substr($user->name, 0, 1);
                                $first_letter_Capital = strtoupper($first_letter);
                              }}
                              @endphp
                              {{$first_letter_Capital}}
                            </span>  
                            @endif
                          </td>

@nakov If I remove this code then it will work properly.

C:\wamp64\www\cms\resources\views/admin/userList/userList.blade.php:83

Laravel error page showing in this line

   @if($user->picture!='profile.png')

@neeraj1005 but please check my reply and you will see what you are doing wrong again

@php 
{{
    $first_letter = mb_substr($user->name, 0, 1);
    $first_letter_Capital = strtoupper($first_letter);
}}
@endphp  

REMOVE THE {{ }} as that's blade, don't mix them:

@php 
$first_letter = mb_substr($user->name, 0, 1);
$first_letter_Capital = strtoupper($first_letter);
@endphp  

{{ }} is blade shortcut for echo (with escape)

change to

                              @php 
                              
                                $first_letter = mb_substr($user->name, 0, 1);
                                $first_letter_Capital = strtoupper($first_letter);

Same error occured again

@neeraj1005 you said this

If I remove this code then it will work properly.

Now when you changed it, which line throws the error. I don't think that it is the same part.. Are you using the same wrong syntax somewhere else?

Do you use Ignition, it will tell you exactly where in the view you get the error.

@nakov In this line it shows error

@if($user->picture!='profile.png')

@neeraj1005 so what does your $user->picture returns? Isn't that a string?

I don't think that you have an error there, if you are looking at the compiled view file, than that would be wrong.

If I was debugging the code, I would remove the if statement completely and check if I still get an error :)

Just the standard reminder here clear those compiled views in between code changes.

That has got me more than once, something was fixed but the compiled view was still loading.

And clear browser cache.

@jlrdw NEVER gets me. NEVER need to clear views
