I'm using the following code to generate a thumbnail and it's URI. The URI works on its own (though it 404's) but whenever I add theme_image_style function it gives a fatal error: "Unsupported operand types in /theme.inc on line 1088"

$image_fields_src = array_column($image_fields, 'uri' );

// thumbnail uri
$thumburi = image_style_path('thumbnail', $image_fields_src[0]);
// generate thumbnail
$thumbnail = theme_image_style('thumbnail', $thumburi );

According to theme_image_style page you tried wrong parameters,

as an example, your code should be something like the following snippet

$variables = array(
        'style_name' => 'thumbnail',
        'path' => $image_fields[LANGUAGE_NONE][0]['uri'],
        'width' => $image_fields[LANGUAGE_NONE][0]['width'],
        'height' => $image_fields[LANGUAGE_NONE][0]['height']
);
$thumbnail_image = theme_image_style($variables);

and in short

$thumbnail_image = theme('image_style', array(
        'style_name' => 'thumbnail',
        'path' => $image_fields[LANGUAGE_NONE][0]['uri'],
));
  • Thanks. Why do I need to add width/height parameters? Shouldn't width and height already by assigned since thumbnail is a default size? – Sam Jan 8 '18 at 11:31
  • Also, I don't want to print the image, just have it accessible by other functions. – Sam Jan 8 '18 at 11:41

    @Sam height and width assigned by your image styles dimension, defaults for thumbnail is 100x100, you can see them on admin/config/media/image-styles , ok instead I print it I'll put it on a variable and do what you want with it. – Yusef Jan 8 '18 at 12:28
  • thanks. Is simply setting it as a variable going to create the thumbnail (on the server) ? Because I seem to be getting 404s from the path unless I actually print the image. – Sam Jan 8 '18 at 13:57
  • @Sam you're welcome, yes, finally you must render it ( by print, echo ,etc) in your theme. – Yusef Jan 8 '18 at 15:57
