Question

我做了这样的搜索，但它没有在文本框中取过值，任何人都可以帮我解决这个问题..谢谢进展........我的模型查询是正确的或任何错误是还有......

如果我输入搜索字词，它会重定向到搜索结果页面但显示空白结果.......并且它说为foreach提供的无效参数（）

如果我打印last_query()，它显示如下......

  SELECT * FROM (`clients`) WHERE  `clientName`  LIKE '%%'

这是我的控制器：

    class Client extends CI_Controller{

        public function __construct(){
            parent::__construct();
            $this->load->model("client_model");
            $this->load->model("interview_model");
            $this->load->model("candidate_model");
            $this->load->model("requirement_model");
        }

    function search()
        {
             $search_term = $this->input->post('search');
             $data['query'] = $this->client_model->search_client($search_term); 
             echo "<pre>"; print_R($this->db->last_query()); exit;
            $data['page_title'] = "Search Results";
            $this->layout->view("client/search",$data);
        }


    }

型号：

    function search_client($search_term)
        {
            $this->db->select('*');
            $this->db->from('clients');
            $this->db->like('clientName',$search_term);

            // Execute the query.
            $query = $this->db->get();

            // Return the results.
           return $query->result_array();
        }

这是index.php（View）中的表单：

<form action="<?php base_url();?>client/search">
                          <input type="text" name="search" id="search" style="width:180px" placeholder="Search here..." />&nbsp;
                          <input type="submit" value="Search" name="submit"  class="btn btn-primary btn-sm"  /></form>

这是search.php（查看）：

    <?php  foreach($query as $client){ ?>

        <tr>
            <td><?php echo $client->clientName;?></td>
            <td><?php echo $client->clientSName; ?></td></td>

            <td>
   <?php } ?>

更改此行：

<form method="POST" action="<?php base_url();?>client/search">

到此：

<form action="<?php echo base_url();?>client/search">

并尝试以下approch：

function search_client($search_term){
    $this->db->select('*');
    $this->db->from('clients');
    $this->db->like('clientName',$search_term);

    // Execute the query.
    $query = $this->db->get();
    if($query->num_rows()>0)
        return $query->result();
    else
        return false;
    }

搜索在codeigniter中不起作用
