Missing Parameter: _

Yii 2.0 General Discussions

I upgraded to php 8.2 and when using FullCalendar, I get a 400 Bad request message and the debug shows a Missing Parameter: _

yii\web\BadRequestHttpException: Missing required parameters: _ in C:\xampp\htdocs\atmtest\vendor\yiisoft\yii2\web\Controller.php:194

Here is the link to the question on Stack overflow with more details.

You call this Yii2 action:

public function 
actionJsoncalendar($start=NULL,$end=NULL,$_=NULL,$wphid)
    {

from JS, passing only one parameter (wphid)

Did this work before? Which PHP version?

I guess the relevant Yii2 core code is:

    public function bindActionParams($action, $params)
    {
       ...
       ...
        foreach ($method->getParameters() as $param) {
            $name = $param->getName();
            if (array_key_exists($name, $params)) {
                ...
            } elseif (
                ...
            } elseif ($param->isDefaultValueAvailable()) {
                $args[] = $actionParams[$name] = $param->getDefaultValue();
            } else {
                $missing[] = $name;
            }
        }

        if (!empty($missing)) {
            throw new BadRequestHttpException(
                Yii::t('yii', 'Missing required parameters: {params}', ['params' => implode(', ', $missing)])
            );
        }

This worked on PHP 7.4 before. There was no other changes to the code.

I would try if this works:

public function 
actionJsoncalendar($wphid, $start=NULL,$end=NULL,$_=NULL)
    {

Worth a try.
I don’t know how Reflection will handle the parameters.

From php.net (perhaps less relevant):

As of PHP 8.0.0, declaring mandatory arguments after optional arguments is deprecated.
and

As of PHP 8.0.0, named arguments can be used to skip over multiple optional parameters.

Thank you, this stopped the 400 error.
I did not realize the $_ is a optional argument.
I didn’t write this code, just trying to debug it.

I am just trying to fix “Trying to access array offset on value of type bool” now.

$approvedtill = Yii::$app->db->createCommand(‘select wph_enddate FROM wpheader where wph_id = (SELECT max(wph_id) FROM wpheader where wph_empid = :empid and wph_status > 0)’, $params)
->queryOne();

$times = Planner::find()->joinWith([‘task’,‘header’])->where([‘pl_empid’ => $empid])->all();

foreach ($times AS $time){
$data[] = array(
‘id’ => $time->pl_id,
‘title’ => $time->pl_title,
‘start’ => date(‘Y-m-d H:i:s’,strtotime($time->pl_start)),
‘end’ => date(‘Y-m-d H:i:s’,strtotime($time->pl_end)),
‘color’ => ($time->pl_title == ‘Lunch’) ? ‘#378006’ : ($time->task->task_priority == ‘Urgent’ ? ‘#a60a0d’ : ($time->task->task_priority == ‘High’ ? ‘#ad3a05’ : ($time->task->task_priority == ‘Medium’ ? ‘#610861’ : ($time->task->task_priority == ‘Low’ ? ‘#086118’ : ‘#05a321’)))),
‘editable’ => ($time->pl_start > $approvedtill[‘wph_enddate’]) ? true : false,
);

    }

I guess you have to test for false first.

Thank for the help.
Any further debugging will be done in the future.
I used this piece of code

if(!$approvedtill){
$approvedtill = date(“Y-m-d”);}
