Question

我希望获得与所选照片相对应的所有相关照片.... 这是我的观点页面

<?php foreach($detail as $row){?>                                       
<img class="primary-image" ima="<?php echo base_url();?>images/<?php echo $row->image;?>" src="<?php echo base_url();?>images/<?php echo $row->image;?>" alt="" />                                          
<?php }?>

我的观看页面是这个

<?php foreach($detail as $row){?>
                                    <!-- product start -->
                                    <div class="col-lg-3 col-md-3 col-sm-3">
                                        <div class="two-product">
                                            <!-- single-product start -->
                                            <div class="single-product">
                                            <!--    <span class="sale-text">Sale</span>-->

                                                    <p><?php echo $row->description;?></p>
                                                </div>

                                    </div>
                <?php }?>

我的控制页面看起来像这样......

public function product_details($p_id)
{
    $data['active_mn']='product_details';
    $data['product']=$this->roxmodel->get_product_details($p_id);
    $id = $this->input->post['category_id'];
    $data['detail']=$this->roxmodel->get_related_image($id,4,0);
    var_dump($data['detail']);
    $this->load->view('product_details',$data);
}

我的模型页面看起来像这样

public function get_related_image($id,$limit,$offset)
{
    $this->db->select('*');
    $this->db->from('gallery');
    $this->db->join('category','category.id=gallery.category_id');
    $this->db->where('category_id',$id);
    $this->db->limit($limit,$offset);
    $query = $this->db->get();
    return $query->result();
}

这是我的表库（表名）

id     image                category_id         
93   img1455604030.jpg       10              
94   img1455605183.jpg       11               
95   img1455616291.jpg       11                
96   img1455617201.jpg       10                
97   img1455617299.jpg       10                
98   img1455681918.jpg       13              
99   img1455681957.jpg       12

这是我点击

查看图片的代码

<a href="<?php echo base_url();?>roxcontrol/product_details/<?php echo $row->id; ?>/<?php echo $row->category_id; ?>">

   my category table is this..

    id  category_name   parent_id
    8   men             0
    9   kids            0
    10  T-shirts        8
    11  Shirts          8
    12  Jeans           8
    13  Pants           8
    14  Shorts          8
    15  Tees            9
    16  Shirts          9
    17  Jeans           9
    18  Pants           9
    19  Shorts & Ber    9
    20  Romper          9

我的桌子包含衬衫，T恤，裤子图片及其对应的category_ids是10,11,12当我选择category_id = 10衬衫图片时我想得到所有category_id = 10件衬衫图片下的相关产品和那样

问题是category_id值为null我没有得到category_id值

Answer 1

我想你想在类别table.right中获取特定类别id的所有图像。如果是这样改变你的模型模型

    public function get_related_image($id)
{
    $this->db->select('*');
    $this->db->from('gallery');
    $this->db->join('category','category.id=gallery.category_id');
    $this->db->where('category.id',$id);
    $query = $this->db->get();
    return $query->result();
}

控制器

 public function product_details($p_id)
{
    $data['active_mn']='product_details';
    $data['product']=$this->roxmodel->get_product_details($p_id);
    $data['detail']=$this->roxmodel->get_related_image($p_id);
    var_dump($data['detail']);
    $this->load->view('product_details',$data);
}

查看

<input type="text" name="categoryid">

我们加入了两个table.so类别名称也得到了这个结果

echo $row->category_name;

Answer 2

这是问题...... 改变模型中的条件

From:  $this->db->where('category_id',$id);
To(Change) : $this->db->where('category.id',$id);

立即检查......

Answer 3

你正在限制

$this->db->limit($limit,$offset);

尝试

$this->db->limit($limit);

Answer 4

<a href="<?php echo base_url();?>roxcontrol/product_details/<?php echo $row->id; ?>/<?php echo $row->category_id; ?>">abc</a>

COntroller代码应为此

public function product_details($p_id, $category_id)
{
    $data['active_mn']='product_details';
    $data['product']=$this->roxmodel->get_product_details($p_id);
    $data['detail']=$this->roxmodel->get_related_image($category_id,4,0);
    var_dump($data['detail']);
    $this->load->view('product_details',$data);
}

我想获得与所选图像相对应的所有相关图像
