我使用CodeIgniter 2.2.
原文链接：https://www.f2er.com/php/139423.html每次访问页面时,我必须更新数据库1.代码工作,但它每次增加2.
示例：如果总视图= 2,一旦页面被单击,总视图应为3,但数据库中的值为4.
我确信我在控制器中只调用一次add_one_to_view_image模型.
调节器
function view(){
$view_id = $this->uri->segment(3);
if($view_id){
$this->property->add_one_to_view_image($view_id);
$prop['prop_detail'] = $this->property->get_single_property_for_view($view_id);
$prop['prop_imgs'] = $this->property->get_single_property_images($view_id);
$prop['amenities'] = $this->property->get_single_property_amenities($view_id);
$prop['latest'] = $this->home->get_latest_properties();
$size = sizeof($prop['latest']);
for($k=0; $k< $size; $k++){
$Image_name = $this->property->get_property_first_image($prop['latest'][$k]->property_id);
if($Image_name){
$prop['latest'][$k]->image=$Image_name[0]->name;
}else {
$prop['latest'][$k]->image="";
}
}
$this->load->view('property_view',$prop);
}
}
模型
function add_one_to_view_image($id){
echo "We in add one to views";
$this->db->where('property_id',$id);
$this->db->set('views','views+1',FALSE);
$this->db->update('property_views');
}
我在模型中添加了一个echo语句.它只打印一次..
