จากรูป หากผมไม่ได้เลือก ข้อมูลจาก dropdown ข้อมูลต้องแสดงทั้งหมด แต่ถ้าเลือกก็จะแสดงข้อมูลที่ select ออกมา
ซึ้งตอนนี้ code น่าจะเกิด error ทำให้ ข้อมูลไม่โชว์ ไม่ทราบว่าผมเขียนตรงไหนผิดครับ
Code (PHP) select.php
<style>
* {
padding: 0;
margin: 0;
box-sizing: border-box;
}
.select_data {
width: 20em !important;
margin-left: auto;
}
.table-data th {
width: 20%;
text-align: center;
}
</style>

ใส่ไว้บนสุดของไฟล์ครับ
Code (PHP)
ini_set('display_errors', '1');
ini_set('display_startup_errors', '1');
error_reporting(E_ALL);

ถ้ากรณีสงสัยว่า JS error ก็ต้องเปิด browser console ดู เพราะไม่งั้นจะให้คนอื่นมาเดาก็ไม่ได้หรอก
JS JavaScript ไม่ใช่ Java มันคนละเรื่องกันนะครับ อย่าเรียกผิด (ผมเคยผิดมาแล้ว)
