Question

我有一个网站，我需要按性别添加搜索选项。

如果用户点击男性性别选项，则必须显示数据库及其相关信息中的所有男性。

同样适用于女性性别选择。

我有代码，但它无法正常工作。

这是代码

我做模特时

$this->db->where('gender');

它给了我输出但是当我使用

时

$this->db->where('gender'='male');

它显示了我的空白页

控制器

        function searchmale()
        {
            if($this->session->userdata('is_logged_in') == true)
            {
                $this->load->view('searchmalegender');
            }
            else
                $this->index();
        }

        function searchmaleconfirm()
        {
            if($this->session->userdata('is_logged_in') == true)
            {

                $data['freemembers'] = $this->freemember_model->searchmale();
            //  $data['domesticmembers'] = $this->domesticmember_model->searchmale();
                //$data['overseasmembers'] = $this->overseasmember_model->search($search);
                //$data['messages'] = $this->messageboard_model->getallmessages();

                $sessiondata = array();
                $sessiondata = $this->session->all_userdata();
                $this->load->view('maleresult',$data);

            }
            else
                $this->index();

Model.php

    function searchmale(){
    $this->db->from('free_members');        
            $this->db->where('gender'= 'male');
            //$this->db->order_by("id", "asc");
            //if ($rows > 0) {
            //  $this->db->limit($rows, $limit_from);
            //}
            $query = $this->db->get();      
            $query_result = $query->result();
            return $query_result;
        }

Answer 1

你应该解决这个问题：

 $this->db->where('gender','male');

Answer 2

希望这有助于：）

试试这段代码：

$this->db->where('gender', 'male');

或

$this->db->where('gender =', 'male');

您可以参考此文档https://www.codeigniter.com/userguide3/database/query_builder.html

Answer 3

在Model.php中，将WHERE子句更改为以下任何一项：

$this->db->where('gender = male');

OR

$this->db->where('gender = ',  'male');

OR

$this->db->where('gender', 'male');

OR

$this->db->where(array('gender', 'male') );
