Question

我在代码点火器中进行多次搜索，列表显示三个选择框专业化，区域，成功全部列出的地方

为MyModel

public  function get_quick_list($locat,$distct,$sepcli)  
{  
    $this->db->select('*');    
        $this->db->from('tbl_doctor');  
        $this->db->join("tbl_specialisation", "tbl_specialisation.spec_id = tbl_doctor.spec_id",'left');

        $this->db->where("(district LIKE '$distct' AND place LIKE '$locat' AND spec_specialise LIKE '$sepcli')");

    $query=$this->db->get()->result_array(); 

 var_dump($query);die();
          return $query;
}

我的控制器

public function get_quick_search() 
{
        $sepcli= $this->input->post('spec');
        $distct= $this->input->post('dist');
        $locat= $this->input->post('locat');
         $data['list'] = $this->Doctor_model->search_listing();
        $data['quck_search'] = $this->search_model->get_quick_list($sepcli,$distct,$locat);
        $data['get_specs'] = $this->specialisation_model->get_specialisation();
        $this->load->helper(array('form', 'url'));
        $this->load->view('customer/header');
        $this->load->view('customer/side_view',$data);
        $this->load->view('customer/quick_search',$data);
        $this->load->view('customer/footer');
}

在您的模型中，您的代码应为

public  function get_quick_list($locat,$distct,$sepcli)  
{  
    $this->db->select('*');    
        $this->db->from('tbl_doctor');  
        $this->db->join("tbl_specialisation", "tbl_specialisation.spec_id = tbl_doctor.spec_id",'left');

        $this->db->where("(district LIKE '%".$distct."%' AND place LIKE '%".$locat."%' AND spec_specialise LIKE '%".$sepcli."%')");

    $query=$this->db->get()->result_array(); 

 var_dump($query);die();
          return $query;
}

让我们解释％通配符在SQL LIKE条件下的工作原理。请记住，％通配符匹配任何长度的任何字符串（包括零长度）。
