Question

我想在提交（搜索框）后保留该值，因此我使用set_value();
我保留了价值但之后我点击了指向下一页的链接（分页），我无法保留该值，因为我没有点击提交按钮，所以如何在不点击提交按钮的情况下保留该值再次？

查看

<?php
    $attr_form= array(
    'class'     => 'form-horizontal',
    'role'      => 'form'           
    );
    echo form_open('dipanddig/search', $attr_form);
    echo '<div class="input-group search-box-width">';
    echo form_input('search', set_value('search'), 'class="form-control search-box-height"');
    echo '<span class="input-group-btn">';
    echo '<button type="submit" class="btn btn-default search-box-height">';
    echo '<span class="glyphicon glyphicon-search">';
    echo '</span>';
    echo '</button>';
    echo '</span>';
    echo form_close();
    echo '</div>';
?>

控制器

    function search(){

        $this->load->library('pagination');

        $data['base_url']   = 'http://localhost:100/dipanddig/dipanddig/search';
        $data['total_rows'] = $this->db->select('name')->like('name', $this->input->post('search'))->get('clothes')->num_rows();
        $data['per_page']   = 1;
        $data['num_links']  = 2;
        $data['records']    = $this->db->select('id,price,name')->like('name', $this->input->post('search'))->get('clothes',$data['per_page'],$this->uri->segment(3));

        $this->pagination->initialize($data);

        $this->load->view('products', $data);   
    }

非常感谢你帮助我。

提交表单后，您必须“记住”查询。使用会话。
内部搜索方法使用会话中的查询值

在搜索表单中添加“清除”按钮

function search()
{
    $this->load->library('pagination');
    // add this
    $this->load->library('session');
    if ($this->input->post('search')) {
        $this->session->set_userdata('search' => $this->input->post('search'));
    }

    $data['base_url']   = 'http://localhost:100/dipanddig/dipanddig/search';
    $data['total_rows'] = $this->db->select('name')->like('name', $this->session->userdata('search'))->get('clothes')->num_rows();
    $data['per_page']   = 1;
    $data['num_links']  = 2;
    $data['records']    = $this->db->select('id,price,name')->like('name', $this->session->userdata('search'))->get('clothes',$data['per_page'],$this->uri->segment(3));

    $this->pagination->initialize($data);
    $this->load->view('products', $data);   
}

HTTP是无状态协议。尽量熟悉惯例。

PS。您还可以从会话中设置表单值以获得更好的用户权限
