Dompdf image generation with if else statement in Laravel 9

I'm studying DOMpdf. I can display images but when I add if else statement the function doesn't work and I always got this error image.

@if ($student->w2c = '')
no image.
@else
// w2c is ture or false alwasy got error image as attach file
<img src="data:image/png;base64, {{ $w2_img }}" width="100%"
class="img-thumbnail">
@endif

but somehow same PDF generate blade file not image if else statement works fine.

@if ($student->br = 'area1')
area1 info
@elseif ($student->br = 'area2')
area2 info
@else
-
@endif

Could someone teach me please?

Solution

  • You need to use == or === when you compare the values. It should be:

    @if ($student->w2c == '')
no image.
@else
// w2c is ture or false alwasy got error image as attach file
<img src="data:image/png;base64, {{ $w2_img }}" width="100%"
class="img-thumbnail">
@endif
