Codeigniter搜索与分页错误

您好我的CI搜索有问题。在第一页中,结果显示正常,但在第二页上显示1064 SQL错误。

您的SQL语法有错误;查看与您的MySQL服务器版本对应的手册,以便在第1行'AND cpt_echip.cpt_echip_nr_inventar LIKE'%%'LIMIT 10,10'附近使用正确的语法

以下是代码(使用的函数):

MODEL:

function search($start, $limit){
        $match = $this->input->post('search');
        $tip_echip = $this->input->post('cpt_tip_echip_nume');
        $q = $this->db->query("SELECT * FROM (cpt_echip)LEFT OUTER JOIN cpt_utl ON cpt_utl.cpt_utl_marca = cpt_echip.cpt_utl_marca WHERE cpt_echip.cpt_tip_echip_id = $tip_echip AND cpt_echip.cpt_echip_nr_inventar LIKE '%$match%' LIMIT $start , $limit");


        $rezultat = $q->result();

        return $rezultat;
    }

function num_filter(){
        $tip_echip = $this->input->post('cpt_tip_echip_nume');
        $this->db->where('cpt_tip_echip_id', $tip_echip);
        $q = $this->db->get('cpt_echip');
        $number = $q->num_rows();

        return $number;
    }

控制器:

function search(){

        $data = $this->helpdesk_model->general();

        $start_row = $this->uri->segment(3);
        $per_page = 10;

        if(trim($start_row) == ""){
            $start_row = 0;
        }

        $config['base_url'] = base_url() . '/index.php/helpdesk/search/';

        $config['total_rows'] = $this->helpdesk_model->num_filter();
        $config['per_page'] = $per_page;
        $config['num_links'] = 10;
        $config['first_link'] = 'Prima pagina';
        $config['last_link'] = 'Ultima pagina';

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

        $data['pagini'] = $this->pagination->create_links();
        $data['query'] = $this->helpdesk_model->search($start_row, $per_page);

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

查看:

<table border="1">
            <tr>
                <th>Nr. Inventar</th>
                <th>Nume</th>
                <th>Utilizator</th>
            </tr>
            <?php foreach($query as $row): ?>
            <tr>
                <td><?php echo anchor('helpdesk/detalii_echipament/'.$row->cpt_echip_nr_inventar, $row->cpt_echip_nr_inventar, array('data-fancybox-type'=>'iframe', 'class'=>'fancybox')); ?></td>
                <td><?php echo $row->cpt_echip_nume; ?></td>
                <td><?php echo $row->cpt_utl_nume; ?></td>
            </tr>
            <?php endforeach; ?>
        </table>
        <?php echo $pagini; ?>

没有搜索和过滤器,分页工作正常。

这意味着$ _POST数组为空。使用指向第二页的链接导航时,不会发布任何内容。您可以通过网址传递搜索数据或在首次提交时存储在会话中并使用它。

只需使用print_r($ _ POST)查看$ _POST数组是什么。
