บันทึกวันที่ 26 ก.ย. 2564 ทำไมใน DB ลงเป็น 1632589200 ครับ |
| |
 |
|
|
 |
 |
|
เปลี่ยน field type เป็น datetime
วันที่ เวลา ใน database มันเก็บเป็น ตัวเลข โดย 0 คือ 1970-01-01 00:00:00
0 คือ 1970-01-01 00:00:00
1 คือ 1970-01-01 00:00:01
2 คือ 1970-01-01 00:00:02
...
...
16...... คือ 2021......
ส่วนการแสดงผล ให้กำหนดด้วย field type
ปล. unixtime มีค่าเป็น วินาที

แสดงว่าปัญหาอยู่ที่ INPUT ครับ ลองดูว่ารับค่าอะไรมา ลอง echo ตัวแปรวันที่ออกมาดูค่าในนั้นครับ
จากนั้นก็เซ็ตค่าให้ตรง format ที่ต้องการแล้วก็เอาไปใส่ในคำสั่ง INSERT

แสดงว่าปัญหาอยู่ที่ INPUT ครับ ลองดูว่ารับค่าอะไรมา ลอง echo ตัวแปรวันที่ออกมาดูค่าในนั้นครับ
จากนั้นก็เซ็ตค่าให้ตรง format ที่ต้องการแล้วก็เอาไปใส่ในคำสั่ง INSERT
ในไฟล์นี้ น่าจะเกี่ยวไหมครับ
หากใช่ ควรปรับคำสั่งตรงไหนไหมครับ

ผมใส่สูตรคำนวณค่าในคอลัมน์ Date แต่ได้ค่า วันเดือนปี ที่ต่างจากค่าในคอลัมน์ timestamp
ทั้งที่วันเดือนปีที่เลือกบันทึกการเข้าชั้นเรียน (Date) เป็นวันเดียวกันกับวันที่คลิกบันทึก (timestamp) ครับ
พอจะทราบสาเหตุไหมครับว่า ทำไมค่าใน Date กับ timestamp ถึงได้วันเดือนปีที่ต่างกัน

echo date('Y-m-d H:i:s', 1632675600);
//2021-09-27 00:00:00

SELECT DATE_FORMAT(FROM_UNIXTIME(1632675600), '%Y-%m-%d');
SELECT DATE_FORMAT(FROM_UNIXTIME(`field_name`), '%Y-%m-%d %H:%i:%s');
SELECT DATE_FORMAT(FROM_UNIXTIME(`date`), '%Y-%m-%d');
