private function displayallsurveys() {
$this->load->database();
$sql = "SELECT * from survey";
$query = $this->db->query($sql);
$data = array();
if ($query->num_rows() > 0) {
$data = $query->result_array();
return $data;
} else {
return $data;
}
}
传递给视图
$data = $this->displayallsurveys();
$this->load->view('SurveyPage', $data);
当我在结尾处展示时
<ul class="nav nav-sidebar">
<li class="active"><a href="#">Home</a></li>
<li><a href="#">Add new Survey</a></li>
<?php foreach ($data as $row) {
$SurveyTitle = $row['SurveyTitle'];
$SurveyId = $row['SurveyId'];
echo'<li id=' . $SurveyId . '><a href=' . $SurveyTitle . '>' . $SurveyTitle . '</a><li>';
}
?>
</ul>
我得到未定义的变量$ data
请有人帮忙

如果你想在视图中使用$ data变量,那么你需要将它作为
传递$this->load->view('SurveyPage', array('data' => $data));
否则,使用以下数组键成为变量名称
$this->load->view('SurveyPage', $data);

传递这样的数据
$data['data'] = $this->displayallsurveys();
$this->load->view('SurveyPage', $data);

这样做:
$data['data'] = $this->displayallsurveys();
$this->load->view('SurveyPage', $data);

作为一种做法,建议使用 $ data [] 变量作为要传递给视图的所有变量的容器。您只需要命名每个键。
例:
$ data ['survey'] = $ this-&gt; displayallsurveys();
$ this-&gt; load-&gt; view('SurveyPage',$ data);
然后在视图中:
<ul class="nav nav-sidebar">
<li class="active"><a href="#">Home</a></li>
<li><a href="#">Add new Survey</a></li>
<?php foreach ($survey as $row) {
$SurveyTitle = $row['SurveyTitle'];
$SurveyId = $row['SurveyId'];
echo'<li id=' . $SurveyId . '><a href=' . $SurveyTitle . '>' . $SurveyTitle . '</a><li>';
}
?>
</ul>
注意:
foreach ($survey as $row)
