我在控制器功能step2内创建会话curs
。视图的表单操作转到该函数,但会话为空。
控制器步骤2:
public function step2($id=null){
$this->load->library('session');
$this->load->model('model_cursos');
if(!$this->input->post()){
if($id == null){
redirect("Cursos/administrar");
}
$this->session->set_userdata('curs',$id);
var_dump($this->session->userdata('curs'));// is not null
}else{
var_dump($this->session->all_userdata()); // is null
exit;
/*$titol = $_POST['titol'];
$data = $_POST['data'];
$horesT = $_POST['horesT'];
$horesD = $_POST['horesD']; */
//var_dump($titol,$data,$horesD,$horesT);
//$this->model_cursos->afegirDades($id,$titol,$data,$horesT,$horesD);
//$this->model_cursos->crearSessions($id,$data,$horesT,$horesD);
}
$this->load->view('step2');
}
查看步骤2:
<form id="step2" method="post" action="<?php echo site_url('Cursos/step2'); ?>">
<label>Titol</label><br>
<input type="text" name="titol" id="titol"><br><br>
<label>Data inici</label><br>
<input type="date" name="data" id="data"><br><br>
<label>Hores totals</label><br>
<input type="number" name="horesT" id="horesT"><br><br>
<label>Hores diaries</label><br>
<input type="number" name="horesD" id="horesD"><br><br>
<input type='submit' name='next' value='Afegir dades'/>
</form>
</div>
答案 0 :(得分:0)
在此行上:
var_dump($this->session->all_userdata());
您的会话为空是正常的,因为当您直接以“ else”状态通过时,您永远不会在其中插入数据。
如果将这样的行放在'if'条件下:
var_dump($this->session->all_userdata());
var_dump($this->session->userdata('curs'));
您看到userdate('curs')的东西了吗?
