Codeigniter数组到字符串转换错误

Question

我在使用update_batch发布时收到此错误.我已经看到了其他帖子,但我的行引用是DB_active_rec.php文件,其他人在他们的MC中看到它.该错误不会阻止update_batch发布,它会返回每个$ rb_items的错误.

控制器:

  public function update_rb(){

    $rb_items = array();
        $rb_id=$this->input->post('id', TRUE);
        $rb_brand=$this->input->post('brand', TRUE);
        $rb_tasted=$this->input->post('tasted', TRUE);
        $rb_rating=$this->input->post('rating', TRUE);
        $rb_comment=$this->input->post('comment', TRUE);

        $i=0;
        foreach($rb_id as $id){
            $rb_items[$i] = array(
                'id'=>$id,
                'brand'=>$rb_brand[$i],
                'rating'=>$rb_rating[$i],
                'comment'=>$rb_comment[$i]
                );
                if(empty($rb_tasted)){
                    $rb_items[$i]['tasted']=0;
                } else if
                (in_array($id,$rb_tasted)){
                $rb_items[$i]['tasted']=1;
                } else{
                    $rb_items[$i]['tasted']=0;
                }                   
            $i++;
        }
        $this->model->update_rb($rb_items);
    }

模型:

    public function update_rb($rb_items){
        $this->rb_db->update_batch('rb_selection',$rb_items,'id');
    }

视图:

    <tr>
        <input type="hidden" name="id[]" value="<?php echo $row['id'];?>">
        <input type="hidden" name="brand[]" value="<?php echo $row['brand'];?>">
        <td><?php echo "<p>".$row['brand']."</p>";?></td>
        <td><input type="checkbox" <?php if($row['tasted'] == 1){echo "checked = checked";}?> name="tasted[]" value="<?php echo $row['id'];?>" id="tasted"/></td>
        <td><input type="text" name="rating[]" <?php echo $row['rating'];?>/></td>
        <td><textarea name='comment[]' id='comment' cols="350"><?php echo $row['comment'];?></textarea></td>
    </tr>

有没有人看到这个错误或知道我的代码中缺少什么？谢谢您的帮助!

print_r($rb_items)返回Array ( [0] => Array ( [rb_id] => 192 [brand] => Napa Valley Soda Co [rating] => r0 [comment] => c0 [tasted] => 1 ) [1] => Array ( [rb_id] => 193 [brand] => Natural Brew [rating] => r1 [comment] => c1 [tasted] => 1 ) [2] => Array ( [rb_id] => 194 [brand] => Naturale 90 [rating] => r2 [comment] => c2 [tasted] => 1 ) ) 包含三个品牌的视图.无论错误如何,所有这些都是正确发布的.

Answer 1

我的CI版本存在问题,即2.1.2.在第1407行的DB_active_rec.php文件中,

这个: $not[] = $k.'-'.$v;

应该: $not[] = $k2.'-'.$v2;
