你能帮我写代码吗?我是 php 和 codeigniter 的新手,我正在尝试将我的查询结果放到视图中,但总是发生错误“致命错误:调用非成员函数 row() -object in”,我试图通过客户 ID 搜索客户信息并尝试将结果获取到视图本身

这是查看代码

 <?php echo form_open('home/cari_id');
?>
<table width='34%' align='left'>
    <tr>
        <td width="54%" align="left">ID Pelanggan</td>

        <td width="36%">
            <?php echo form_input('id',set_value('id'));?>
            <?php echo form_error('id');?>
        </td>
        <td width="10%">
            <?php echo form_submit('submit','Cari');?>
        </td>
    </tr>
</table> 

<br /><br />

<table width="68%" align="left">
    <tr>
        <td width="17%" align="left">Nama</td>
        <td>
            <?php   
                $row = $record->row();
                $nama1 = array(
                         'name' => 'nama',
                         'maxlength' => '100',
                         'size' => '50',
                         'style' => 'width:120%');
                echo form_input($nama1,$row->nama);?>
            <?php echo form_error('nama');?>
        </td>
    </tr>
    <tr>
    <td align="left">Alamat</td>
    <td>
        <?php 
            $alamat1 = array(
                        'name' => 'alamat',
                        'rows' => '5',
                        'cols' => '3',
                        'style' => 'width:200%');
            echo form_textarea($alamat1,$row->alamat);?>
        <?php echo form_error('alamat');?>
    </td>
    </tr>
    <tr>
        <td align="left">Golongan</td>
        <td width='29%'>
            <?php 
                $gol1 = array(
                        'name' => 'gol',
                        'maxlength' => '100',
                        'size' => '50',
                        'style' => 'width:40%');
                echo form_input($gol1,$row->golongan);?>
            <?php echo form_error('gol');?>
        </td>
        <td width="10%" align="left">Tarif</td>
        <td width="44%">
            <?php 
                $tarif = array(
                'name' => 'tarif',
                'maxlength' => '100',
                'size' => '50',
                'style' => 'width:30%');
                echo form_input($tarif,$row->tarif);?>
            <?php echo form_error('tarif');?>
        </td>
    </tr>
</table>

这是我的代码控制器

public function cari_id()
{
    $this->auth->restrict();
   // mencegah user mengakses menu yang tidak boleh ia buka
    $this->auth->cek_menu(4);

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

    $this->form_validation->set_rules('id', 'ID Pelanggan', 'trim|required');
    //$this->form_validation->set_rules('nama','Nama','trim'|'required');
    //$this->form_validation->set_rules('alamat','Alamat','trim'|'required');
    //$this->form_validation->set_rules('gol', 'Golongan', 'trim|required');
    //$this->form_validation->set_rules('tarif', 'Tarif', 'trim|required');
    $this->form_validation->set_error_delimiters(' <span style="color:#FF0000">', '</span>');
    $id_pel = $this->input->post('id') ;
    //$data1 = $this->usermodel->get_list_bayar_pel($id_pel);
    //$data=$data1->row();
    $data1 = $this->usermodel->get_list_bayar_pel($id_pel);
    $data['record'] = $query->result_array();
    $this->template->set('title','Input Pembayaran | POS Application');
    $this->template->load('template','admin/input_pembayaran',$data);

}

和型号代码

function get_list_bayar_pel($id)
{
    $this->db->select('b.name as nama, b.address as alamat, c.nm_gol as golongan,d.rate_value as tarif');
    $this->db->from('account_t a, account_nameinfo_t b, golongan_t c, (select rate_value from rate_t a, golongan_t b where a.id_gol = b.id_gol) d');    
    $this->db->where('a.id_account = b.obj_id');
    $this->db->where('a.id_gol = c.id_gol');
    $this->db->where('a.id_account = "'.$id.'"');
    $result = $this->db->get();
    return $result;
    }

谢谢之前

在您的控制器中,您正在获取多行

$data['record'] = $query->result_array();

它应该是

$data['record'] = $query->row();

并在视图中给出 $row = $record; 而不是 $row = $record->row();

根据您的代码,您使用 row() 函数在视图中检索数据,同时它已使用以下方法在控制器中获取:

 $data['record'] = $query->result_array();


只需使用其中之一(在控制器中):

$data['record'] = $query->result_array();

或者

$data['record'] = $query->row();

然后处理视图中的数组

希望能帮助到你 :)


注意:
-我建议您使用 result_array() 将数据检索到数组中

在你的控制器中写这个

$data['record'] = $query->row();

并在视图中删除 php 代码写入

 <?php   

                $nama1 = array(
                         'name' => 'nama',
                         'maxlength' => '100',
                         'size' => '50',
                         'style' => 'width:120%');
                echo form_input($nama1,$record->nama);?>
            <?php echo form_error('nama');?>

在模型中

$result = $this->db->get('tablename')->row();

$record 没有返回单行,它返回一个集合,要么使用 current($record)->row() 要么获取单行。
