I have three Fields

• title
• body
• images[]

the body is required without image, so I did the following:

   $request->validate([
        'title' => 'required|string|max:' . (int) Setting::getValue('titlemaxchars'),
        'body'  => [
            'required_without:images',
            'string',
            'min:'.(int) Setting::getValue('postminchars'),
            'max:'.(int) Setting::getValue('postmaxchars'),
        ],
    ]);

    if ($request->hasFile('images')) {
        foreach ($request->file('images') as $file) {
            Validator::validate(['photo' => $file], [
                'photo' => ['required', 'file', 'image', 'max:2048'],
            ]);
        }
    }

The issue is with the following:

• body.string
• body.min
• body.max

I don't want them to make any error message if there is an Image, and the error message should only appear if there are no images.

THIS WORKS FOR ME!

 $request->validate([
        'title' => 'required|string|max:' . (int) Setting::getValue('titlemaxchars'),
    ]);

    if(!empty($request->hasFile('images'))){
        $request->validate([
            'body'  => 'nullable',
        ]);
    }else{
        $request->validate([
            'body'  => [
                'required',
                'string',
                'min:'.(int) Setting::getValue('postminchars'),
                'max:'.(int) Setting::getValue('postmaxchars'),
            ],
        ]);
    }
