การอ่านฟิลด์ TEXT (ไม่ใช่ VARCHAR) จาก MySQL ด้วย PHP ไม่แสดงในพื้นที่ข้อความ HTML
ฉันกำลังพยายามสร้างหน้าแก้ไขที่อ่านข้อมูลจาก MySQL ด้วย PHP แล้วแสดงในรูปแบบ HTML\nฟิลด์ปกติ เช่น VARCHAR แสดงได้อย่างถูกต้อง แต่ฉันประสบปัญหาในการแสดงฟิลด์ TEXT

\nAnswer
วิธีแก้ปัญหา:
ลองสะท้อนค่าระหว่างแท็ก textarea ไม่ใช่ในแอตทริบิวต์ของค่า:
\n<textarea class="form-control" type="textarea" name="minreq" id="minreq" maxlength="6000" rows="5"><?php echo $minreq; ?></textarea>\nAnswer
วิธีแก้ไข:
โปรดลบค่าออกจากพื้นที่ข้อความและเขียนโค้ดดังนี้:
\n//here is the valid code...this will 100% work.\n<textarea class="form-control" type="textarea" name="posdetails" id="posdetails" maxlength="6000" rows="5">\n <?php echo $posdetails; ?>\n</textarea>\n
