Yii CJSON MODEL null 

1 $criteria = new CDbCriteria();
2 $criteria->select = "`id`,`name`";
3 $criteria->addInCondition('id', array(1,2,3,4,5));
4 $criteria->order = 'id desc';
5 $student = MODELNAME::model()->findAll($criteria);
6 echo CJSON::encode($student);

 

 

这个东西传出来的json
有好多null的字段

 

解决办法

 1 $rows=array();
 2 foreach($student as $i=>$user) {
 3 $rows[$i]=array_filter($user->attributes);
 4 }
 5 echo CJSON::encode($rows);
 6 
 7  
 8 
 9 array_filter:
10 
11 <?php
12 
13 $entry = array(
14              0 => 'foo',
15              1 => false,
16              2 => -1,
17              3 => null,
18              4 => ''
19           );
20 
21 print_r(array_filter($entry));
22 ?>
23 
24 以上例程会输出：
25 
26 Array
27 (
28     [0] => foo
29     [2] => -1
30 )
