كيفية جلب صورة الملف الشخصي للمستخدم باستخدام user_name في PHP؟

لقد قمت بتطوير ملف تعريف مستخدم حيث يمكنه تحميل صورته عند تسجيل الدخول لأول مرة. يتم حفظ صورة ملفه الشخصي في مجلد ويتم حفظ مسار الصورة في قاعدة البيانات. الآن أريد جلب تلك الصورة باستخدام اسم المستخدم الخاص به، والذي جعلته فريدًا. عندما يقوم المستخدم بحفظ صورة ملفه الشخصي، من خلال زر إرسال مخفي، أقوم بحفظ اسم المستخدم الخاص به في قاعدة البيانات.
لكن جلب رمز الصورة هذا لا يعمل

ما حاولت:

هذا هو ترحيبي الكامل. php حيث يقوم المستخدم بتغيير صورة ملفه الشخصي والاطلاع على تفاصيل ملفه الشخصي.
