בניית מודול CRUD

בניית הדרכה CRUD מודול

Section titled “בניית הדרכה CRUD מודול”

מדריך זה מנחה אותך בבניית מודול CRUD (צור, קרא, עדכן, מחק) שלם עבור XOOPS. ניצור מודול “הערות” המאפשר למשתמשים לנהל הערות אישיות.

דרישות מוקדמות

Section titled “דרישות מוקדמות”
  • הושלם הדרכה של Hello-World-Module
  • הבנה של מושגי PHP OOP
  • ידע בסיסי SQL

סקירת מודול

Section titled “סקירת מודול”

תכונות מודול הערות:

  • צור, הצג, ערוך ומחק הערות
  • ממשק ניהול אדמין
  • הערות ספציפיות למשתמש
  • ארגון קטגוריות
  • פונקציונליות חיפוש
