Show drawing conditionally in laravel-excel

Question

I have an Export which looks like this:

class CatalogExport implements WithHeadings, WithDrawings, WithMapping, FromCollection

and I want the Drawing to be shown conditionally, but I don't really know how to do it.

I tried it this way:

public function drawings()
    {
        $drawing = new Drawing();
        if($this->semnat === 1)
        {
        $drawing->setName('Semnatura');
        $drawing->setDescription('This is my logo');
        $drawing->setHeight(100);
        $drawing->setCoordinates('F3');
        $drawing->setPath(null);
        $drawing->setPath(storage_path('app/public/' . $this->imgPath));
        }

        return $drawing;
    }

For any other value than 1 the fields will remain not completed, so I thought there might be no drawing shown. But then I get this error:

File not found! 

So, is there any way to show this drawing conditionally, other than creating two export classes, one which implements WithDrawings and one which doesn't? (but would create a lot of duplicate code)

Answer 1

It looks like there's some code missing from your question.

Regardless, I'd rejig your drawing function to be like this:

public function drawings()
{
    if($this->semnat === 1 && $this->imgPath)
    {
        $drawing = new Drawing();
        $drawing->setName('Semnatura');
        $drawing->setDescription('This is my logo');
        $drawing->setHeight(100);
        $drawing->setCoordinates('F3');
        $drawing->setPath(null);
        $drawing->setPath(storage_path('app/public/' . $this->imgPath));
        return $drawing;
    }

    return null;
}

This code checks to see if imgPath is set, and also returns null if semnat isn't 1 or imgPath is not set.
