我在这里有意见
<?php echo form_open('c_kategorimaterial/tambah'); ?>
<table>
<tr>
<td>Kode Kategori Material / Jasa</td> //primary key of table
<td><?php $inkode=array('name' => 'kkmj', 'disabled' => 'disabled', 'value' => $nextval, 'class' => 'GUI'); echo form_input($inkode) ?></td>
<td class="error"> <?php echo form_error('kkmj'); ?></td>
//i make the form_input disabled, because the value is
//auto generated from the last ID of table in database
</tr>
<tr>
<td>Nama Material / Jasa</td>
<td><?php $innama=array('name' => 'nmj', 'class' => 'GUI'); echo form_input($innama) ?></td>
<td class="error"> <?php echo form_error('nmj'); ?></td>
</tr>
<tr>
<td></td>
<td><?php $intambah=array('name' =>'login','class' =>'button','value' => 'Tambah'); echo form_submit($intambah); echo nbs(); $inreset=array('name' =>'reset','class' =>'button','value' => 'Hapus'); echo form_reset($inreset); ?></td>
</tr>
<?php echo form_close(); ?>
并将值传递给控制器
function tambah()
{
$id = $this->input->post('kkmj');
$nama = $this->input->post('nmj');
$this->form_validation->set_rules('nmj','Nama','trim|required|min_length[2]|max_length[20]|xss_clean');
if($this->form_validation->run() == false)
{
$lastval = $this->m_admin->getlastval('KKMJ','ms_kategori_material','kode_kategori_material_jasa');
$data['nextval'] = $this->m_admin->gencode('KKMJ',3,$lastval);
$data['title'] = 'QB Tambah Kategori Material';
$this->load->view('head',$data);
$this->load->view('content/add_kategori_material',$data);
}
else
{
echo 'id adalah '.$id.' namanya adalah '.$nama; //$id is not printed
}
}
然后我用“水”填充第二个字段并单击按钮。我的页面显示带有文本的空白屏幕id adalah namanya adalah water
身份证怎么不打印?我该如何解决这个问题?
