我在 CI 视图页面中收到错误,因为为 foreach() 提供的参数无效。这是我的代码:
我的数据库:(彭耶瓦表)
**id_penyewa
nama_penyewa
alamat
no_telp**
(贾米南表)
**id_penyewa
jenis_jaminan
ket_jaminan**
在控制器(penyewa.php)
function Penyewa()
{
parent::Controller();
$this->load->database();
$this->load->model('model_tampil');
}
function tambah()
{
$ck=$this->input->post('id_penyewa');
if($ck!='')
{
$this->model_tampil->insertPenyewa();
}
$this->load->view('tampilpenyewa');
}
function sukses()
{
echo "Data berhasil di input!";
?>
<br />
<a href="<?php echo base_url();?>/index.php/login/input_penyewa">Tambah Data</a>
<br />
<a href="<?php echo base_url();?>/index.php/login/tampil_penyewa">Lihat Data</a>
<?php
}
在模型中(model_tampil.php)
function getPenyewa(){
$this->db->select('*');
$this->db->from('penyewa');
$this->db->join('jaminan','jaminan.id_penyewa = penyewa.id_penyewa');
$q = $this->db->get();
$rows = $q->num_rows();
$q_result = $q->result();
if($rows>0){
foreach($q_result as $row){
$data[] = $row;
}
return $data;
}
}
function insertPenyewa()
{
/*$this->db->trans_start();
$this->db->query('INSERT INTO penyewa VALUES($id_penyewa, $nama_penyewa, $alamat, $no_telp, $jenis_jaminan)');
$table1_id = $this->db->insert_id();
$this->db->query('INSERT INTO jaminan VALUES(id_penyewa,' . $table1_id .',jenis_jaminan)');
$this->db->trans_complete(); */
$this->id_penyewa=$this->input->post('id_penyewa');
$this->nama_penyewa=$this->input->post('nama_penyewa');
$this->alamat=$this->input->post('alamat');
$this->no_telp=$this->input->post('no_telp');
$this->jenis_jaminan=$this->input->post('jenis_jaminan');
$this->db->insert('penyewa',$this);
redirect('penyewa/sukses');
}
在视图中 (tampilPenyewa.php)
<center> <h3>Tabel data Penyewa</h3> <table border="1"> <tr align="center" bgcolor="#33CC99"> <td width="100">ID Penyewa</td> <td width="200">Nama Penyewa</td> <td width="120">Alamat</td> <td width="150">Nomor Telepon</td> <td width="150">Jenis Jaminan</td> <td>Tindakan Lanjut</td> </tr> <?php foreach ($records as $row) : ?> <tr height="35"> <td> <?php echo $row->id_penyewa; ?></td> <td> <?php echo $row->nama_penyewa; ?></td> <td> <?php echo $row->alamat; ?></td> <td> <?php echo $row->no_telp; ?></td> <td> <?php echo $row->ket_jaminan; ?></td> <td></td> </tr> <?php endforeach; ?> </table> <br /> <a href="<?php echo base_url();?>/index.php/login/input_penyewa">Tambah Data</a>
并在视图中(inputpenyewa.php)

好吧,如果我的问题非常非常多,我很抱歉..谢谢你:)
更新:
好的,我已经这样做了,但没有任何结果,我的页面再次错误..
而且,我想再问一次,model_tampil->getPenyewa() 有什么错误吗?
这是脚本:
function getPenyewa(){
$this->db->select('*');
$this->db->from('penyewa');
$this->db->join('jaminan','jaminan.id_penyewa = penyewa.id_penyewa');
$q = $this->db->get();
$rows = $q->num_rows();
$q_result = $q->result();
if($rows>0){
foreach($q_result as $row){
$data[] = $row;
}
return $data;
}
}
我想从 1 页 inputpenyewa.php 将数据输入到我的本地主机中的 2 个表中。
