เรื่องมีอยู่ว่า ผมได้แก้โคด _form.php ของ research ซึ่งเดิมเป็น textfield จะเปลี่ยนให้เป็น dropDownlist ที่ดึงข้อมูลจาก ตาราง researcher

ซึ่งเมื่อแก้จาก textfield เป็น dropDownlist เกิด error ขึ้น**

โคดที่ผมใช้ครับ

<div>

<?php echo $form->labelEx($model,'idresearcher'); ?>

<?php echo $form->textField($model,'idresearcher'); ?>

<?php echo $form->error($model,'idresearcher'); ?>

</div>

ไม่ทราบว่ากรณีอย่างนี้เกิดเพราะอะไรครับ

** ---------------------error --------------------

มันบอกว่าไม่มี attribute researcher ครับ ดูจาก code ข้างบนจะเห็นว่า attribute คือ idresearcher ครับ เปลี่ยนตรงนี้ครับ

dropDownList($model,'idresearcher',
