Question

这是我的观看代码

<?php
Yii::import('common.extensions.chartjs.assets.js.*');
echo $eventdata['event_name']."<br>";
echo $contribution = Event::model()->contribution($eventdata['id'])."<br>";
echo $percentage = ($contribution/$eventdata['funding_goal_amount'])*100;
echo "<br>".Event::model()->dayleft($eventdata['id'])."<br>";
if($invites) {
$sms = 0;
$email = 0;
$totalinvites = count($invites);
foreach ($invites as $key => $data) {
    if($data['type'] == 3) {
        ++$sms;
    }
    if($data['type'] == 1) {
        ++$email;
    }
}

//gets the last 30 days
$d = array();
for($i = 0; $i < 28; $i++) 
$d[] = date("d", strtotime('-'. $i .' days'));
$data=array(
);
$con=0;
foreach ($d as $key => $value) {
    echo($value);
    echo("<br>");
    if($con==1)
    {
        die;
    }

    $data[]=callinvites($value);
}
echo(var_dump($data));
echo "Total invites are $totalinvites <br>";
echo "Invites by sms are $sms <br>";
echo "Invites by email are $email <br>";

}


echo "Google analytic api to come here <br>";
echo Event::model()->peopleContributed($eventdata['id'])."<br>";
if($contributors) {
    foreach ($contributors as $key => $data) {
        echo $data['fname']."<br>";
    }
}
?>

?>

当我调用函数callinvites并说undefined variable : invites in yii view

时，我收到错误消息

虽然我用过这个

echo(var_dump($invites));

这显示了一个大小为20的数组，其中包含数据库中的值，那么为什么会发生错误？

Answer 1

在callinvites功能中尝试更改此行

foreach ($invites as $key => $value) {

到

foreach ($this->invites as $key => $value) {

未定义的变量：在yii视图中邀请
