뷰페이지 소스도 보여주세요

어떤 변수값이 넘어 오지 않나요?

category_id ?

category_code ?

뷰페이지를 보아야 할거 같은데요...

아직 실력이 모자라서 정확한 답을 드리긴 어렵고

제가 사용한 소스를 보여 드릴께요.

			<?php echo form_open('calendar/index', 'id="schedule" name="schedule"'); ?>

data : formdata,

위와 같이 넘겨주어야 합니다.

'id ' 로 넘겨주면 $_POST['id'] 로 받아야 하지 않을까요?

darkninja님 답변 너무 감사합니다.

아래와 같이 확인하면 이런 문제가 나옵니다.

$('#category').change(function(){ 

var id=$(this).val();

alert(id);  -> category 값만  나오고

---------------------------------------------------------------------------

<select class="form-control" name="category" id="category"> 
<option>카테고리선택</option>
<?php foreach($category as $row):?> 
<?if(!$_GET['category_id']) { ?>
<option value="<?php echo $row->category_id;?>"><?php echo $row->category_name;?> (<?php echo $row->category_code;?>)</option>
<?php } else { ?>
<option value="<?php echo $row->category_id;?>"><?php echo $row->category_name;?> (<?php echo $row->category_code;?>)</option>
<?php } ?>
<?php endforeach;?> 
</select>

<input type="text" id="category_code" name="category_code"  value="<?php echo $row->category_code; ?>">
<input type="text" id="category_name" name="category_name"  value="<?php echo $row->category_name; ?>">

<input type="text" name="subcategory_name" required="required" class="form-control col-md-7 col-xs-12"> 

------------------------------------------------------------------------------------------------------------------------------------------------------------------

var formName = "form_categories1";
var category= $("form[name="+formName+"][category]");
var category_code = $("form[name="+formName+"][category_code]");
var category_name= $("form[name="+formName+"][category_name]");

alert(category_name);

위의 코드가 동작할지는 모르겠지만
이런식으로 input에서 category_code 값을 저장해 두어야 나중에 사용할수 있습니다.
