我有一个由 jquery 调用的控制器函数:
function get_sku_prices(){
$this->load->model('Sales_model');
if (isset($_GET['term'])){
$q = strtolower($_GET['term']);
$this->Sales_model->get_sku_price($q);
}
}
模型 get_sku_price 为:
function get_sku_price($q){
$this->db->select('price');
$this->db->where('sku', $q);
$query = $this->db->get('products');
if($query->num_rows > 0){
foreach ($query->result_array() as $row){
$row_set[] = htmlentities(stripslashes($row['price'])); //build an array
}
$this->output->set_content_type('application/json')->set_output(json_encode($row_set));
}
}
我想要的是将上述查询的结果(本质上是select price from products where sku=36113
)返回到我的视图表单上的输入变量“价格”。
我的视图语法是:
<html>
<head>
<title>
Capture blank Order

我的模型查询是否正确?帖子是否正确传递给他的模型?我怎样才能验证这一点?
再次感谢。
