Undefined variable : invites in yii view - php

Question

This is my view code
<?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>";
}
}
?>

?>
I get an error when I call the function callinvites and says undefined variable : invites in yii view
Although I used this
echo(var_dump($invites));
this shows an array of size 20 having values from the database, so why is the error happening?

Answer 1

In your callinvites function try changing this line
foreach ($invites as $key => $value) {
to
foreach ($this->invites as $key => $value) {
