[英]how do i get the data from view in codeigniter
我的Codeigniter不好,我還在學習。 所以我需要你們的幫助。
我想從數據庫中獲取ID等於下拉列表按鈕的值的數據。這是我的代碼。
這是我的控制器: controller.php
function getdataload(){
$this->load->view('data',$data);
}
我真的不知道在控制器中放什么。
這是我的觀點: view.php
<html>
<body>
<label for="member">Member</label>
<select class="form-control" id="member" name="member" required onchange="showCustomer(this.value)">
<option selected="" value="">--select--</option>
<?php foreach ($members as $row): ?>
<option value="<?php echo $row->mem_id; ?>"><?php echo ucwords($row->mem_fname.' '.$row->mem_lname) ?></option>
<?php endforeach ?>
</select>
</body>
</html>
<script>
$('#member').on('change',function(){
$.post('<?php echo base_url("transactions/getdataload")?>',
{
mem_id:$(this).val()
}).done(function(res)
{
$('#select_member').text(res);
});
});
</script>
這是從控制器data.php調用的另一個視圖
<?php
$q = intval($_GET['member']);
$con = mysqli_connect('localhost','root','','global89_point');
if (!$con) {
die('Could not connect: ' . mysqli_error($con));
}
mysqli_select_db($con,"global89_point");
$sql="SELECT * FROM loading_service WHERE member='".$q."'";
$result = mysqli_query($con,$sql);
echo "<table>";
echo "<tr>";
echo " <th>";
echo "Member ID";
echo "</th>";
echo "</tr>";
while($row = mysqli_fetch_array($result)) {
echo "<tr>";
echo "<td>" . $row['member'] . "</td>";
echo "</tr>";
}
echo "</table>";
mysqli_close($con);
?>
請幫我這個家伙。
如果不使用模型,並且應該向控制器寫入數據庫邏輯,則應該從控制器調用數據庫庫:
public function result()
{
$this->load->library('database')
$data = array();
$service_list = $this->db->query("SELECT * FROM loading_service WHERE member='".$q."'")->result_array();
$data['service'] = $service_list;
$this->load->view('result', $data);
}
在此result
視圖中,您將獲得$service
數組,並且可以輕松地對此進行迭代。
Our model in CodeIgniter will be placed in application/models/form_model.php
<?php
class Form_model extends Model {
function Formmodel() {
// load the parent constructor
parent::Model();
}
function submit_posted_data() {
// db is initialized in the controller, to interact with the database.
$this->db->insert('loading_service ',$_POST);
}
function get_all_data() {
// again, we use the db to get the data from table ‘form’
$data['result']=$this->db->get('loading_service');
return $data['result'];
}
}
?>
controller
ss Form extends Controller {
function Form(){
// load Controller constructor
parent::Controller();
// load the model we will be using
$this->load->model('form_model');
// load the database and connect to MySQL
$this->load->database();
// load the needed helpers
$this->load->helper(array('loading_service','url'));
}
//Display the posted entries
function index() {
$data['member']='Form Data';
//use the model to get all entries
$data['result'] = $this->form_model->get_all_data();
// load 'forms_view' view
$this->load->view('forms_view',$data);
}
//Process the posted loading_service
function submit() {
//use the model to submit the posted data
$this->form_model->submit_posted_data();
redirect('loading_service');
}
}
?>
you can refer this code..It will helpful for u...
