Question

我有以下代码根据所选位置加载网站中的数据，更改ajax被激活并在控制器中获取值，从控制器到模型并进入sql的where子句，sql的结果未显示在网站上。但总是进入模型

的其他循环

查看：

$(document).on('change','#delvloc',function(e){
      e.preventDefault();  // stops the jump when an anchor clicked.
      var title = this.value; // anchors do have text not values.

      $.ajax({
        url: 'index.php?route=product/category/newfunc',
        data: {'title': title}, // change this to send js object
        type: "get",
        success: function(data){
           //document.write(data); just do not use document.write
           console.log(data);
        }
      });
   });

控制器：

public function newfunc(){               
           $data = array(
                    'title' => $this->request->get['title']                 
                        );  
                    $this->load->model('catalog/product');      
              $this->model_catalog_product->getProducts($data);         


    }

型号：

    public function getProducts($data = array()) {
    $sql="SELECT p.product_id,p.city, (SELECT AVG(rating) AS total FROM monster_review r1 WHERE r1.product_id = p.product_id AND r1.status = '1' GROUP BY r1.product_id) AS rating, (SELECT price FROM monster_product_discount pd2 WHERE pd2.product_id = p.product_id AND pd2.customer_group_id = '1' AND pd2.quantity = '1' AND ((pd2.date_start = '0000-00-00' OR pd2.date_start < NOW()) AND (pd2.date_end = '0000-00-00' OR pd2.date_end > NOW())) ORDER BY pd2.priority ASC, pd2.price ASC LIMIT 1) AS discount, (SELECT price FROM monster_product_special ps WHERE ps.product_id = p.product_id AND ps.customer_group_id = '1' AND ((ps.date_start = '0000-00-00' OR ps.date_start < NOW()) AND (ps.date_end = '0000-00-00' OR ps.date_end > NOW())) ORDER BY ps.priority ASC, ps.price ASC LIMIT 1) AS special FROM monster_product p LEFT JOIN monster_product_description pd ON (p.product_id = pd.product_id) LEFT JOIN monster_product_to_store p2s ON (p.product_id = p2s.product_id) WHERE pd.language_id = '1' AND p.status = '1' AND p.date_available <= NOW() AND p2s.store_id = '0'"
    if (!empty($data['title'])) {
                $sql .= " and p.city='". $data['title'].  "' GROUP BY p.product_id";            
            }
    else{$sql .= " and p.city='Pune' GROUP BY p.product_id";}

}

我的HTML：

交货地点：

            <select name="delvloc" id="delvloc" style="width: 100px;" ">
                        <?php foreach ($city as $user_group) { ?>
                        <?php if ($user_group['city'] == $user_group_id) { ?>
                        <option value="<?php echo $user_group['user_group_id']; ?>" selected="selected"><?php echo $user_group['city']; ?></option>
                        <?php } else { ?>
                        <option value="<?php echo $user_group['city']; ?>"><?php echo $user_group['city']; ?></option>
                        <?php } ?>
                        <?php } ?>
                </select>
                </li>

在模型中

function getProducts($data) {
    $sql="SELECT p.product_id,p.city, (SELECT AVG(rating) AS total FROM monster_review r1 WHERE r1.product_id = p.product_id AND r1.status = '1' GROUP BY r1.product_id) AS rating, (SELECT price FROM monster_product_discount pd2 WHERE pd2.product_id = p.product_id AND pd2.customer_group_id = '1' AND pd2.quantity = '1' AND ((pd2.date_start = '0000-00-00' OR pd2.date_start < NOW()) AND (pd2.date_end = '0000-00-00' OR pd2.date_end > NOW())) ORDER BY pd2.priority ASC, pd2.price ASC LIMIT 1) AS discount, (SELECT price FROM monster_product_special ps WHERE ps.product_id = p.product_id AND ps.customer_group_id = '1' AND ((ps.date_start = '0000-00-00' OR ps.date_start < NOW()) AND (ps.date_end = '0000-00-00' OR ps.date_end > NOW())) ORDER BY ps.priority ASC, ps.price ASC LIMIT 1) AS special FROM monster_product p LEFT JOIN monster_product_description pd ON (p.product_id = pd.product_id) LEFT JOIN monster_product_to_store p2s ON (p.product_id = p2s.product_id) WHERE pd.language_id = '1' AND p.status = '1' AND p.date_available <= NOW() AND p2s.store_id = '0'"; # Mssing ; here
    if (!empty($data['title'])) 
    {
        $sql .= " and p.city='". $data['title'].  "' GROUP BY p.product_id";            
    }
    else{
        $sql .= " and p.city='Pune' GROUP BY p.product_id";
    }

    $query = $this->db->query($sql);
    $result = $query->result_array();
    return $result;
}

在控制器中

function newfunc()
{  

    $data = array(
        'title' => $this->request->get['title']                 
    );  

    $this->load->model('catalog/product');      
    $result = $this->model_catalog_product->getProducts($data);  

    $response['data'] = '';

    if (empty($result)) 
    {
        $response['data'] = false;
    } 
    else {
       $response['data'] = $result;
    }
    echo json_encode($response);
}
