เพิ่มโค๊ดด้านล่างนี้เข้าไปในไฟล์ function.php เป็น function สำหรับ อัพเดทจำนวน views และแสดงจำนวน views
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 |

จากนั้นให้นำโค๊ดด้านล่างนี้ไปใส่ใว้ในไฟล์ single.php (หน้าแสดงบทความ) เพื่อที่จะทำการอัพเดทจำนวน views และแสดงจำนวน views
1 2 3 |
<?php if(function_exists('bac_PostViews')) { echo bac_PostViews(get_the_ID()); }?> |
สำหรับหน้ารวมบทความ (content.php หรือ index.php ) ให้ใช้โค๊ดด้านล่างนี้เพื่อแสดงจำนวน Views ของแต่ละบทความ (แสดงอย่างเดียว ไม่อัพเดทจำนวน Views)
1 |
<?php echo (int) get_post_meta(get_the_ID(), 'post_views_count', true) . ' View(s)'; ?> |
หาต้องการแสดงคอร์ลัมน์ view ในส่วนของ Admin Dashboard ให้เพิ่มโค๊ดด้านล่างนี้เข้าไปในไฟล์ function.php
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 |
