Question

原始代码可让您选择1个事件。每个ID都包含车间名称，地点和时间。

$event_hour_details = TT_DB::getEventHours(array(
                'event_hours_id' => $event_hour_id,
                'user_id' => $user_id,
            ));

$event_hour_details = $workshop_ids[0][0];

$event_hour_details->column_title

我想选择多个活动因此，我在JS中创建了一个数组，并将其转换为字符串。 ID从JS（xxx，xxx，xxx，...）发送到PHP，在那里我将其爆炸成一个数组

$workshop_ids = explode(',', $event_hour_id);


foreach ($workshop_ids as $workshop_id){
  $event_hour_details = TT_DB::getEventHours(array(
    'event_hours_id' => $workshop_id,
    'user_id' => $user_id,
            ));
        }


$event_hour_details = $workshop_ids[0][0];??

$event_hour_details->column_title??

如何显示所有事件标题？抱歉我缺乏知识

哦，我以为TT_DB :: getEventHours（array（））创建了一个数组。

 foreach($workshop_ids as $event_details) { 
$event_data .= "Workshop: " . $event_details . "<br />"; }

请给我讲习班ID。但是使用


foreach($event_hour_details_array as $event_hour_details) { 
echo $event_hour_details->column_title."<br>"; }

由于某种原因，该值返回空吗？

调试代码：

Array
(
    [0] => Array
        (
            [0] => stdClass Object
                (
                    [start] => 09.00
                    [end] => 17.00
                    [description_1] => Je sterker voordoen dan je bent?
                    [description_2] => Vrijdag 18 Oktober
                    [event_title] => Exoskeletons / VR
                    [column_title] => Willemen Construct en Eifage Benelux
                    [booking_count] => 10
                    [available_places] => 150
                    [slots_per_user] => 30
                    [current_user_booking_count] => 0
                    [current_guest_booking_count] => 0
                )

        )

    [1] => Array
        (
            [0] => stdClass Object
                (
                    [start] => 09.00
                    [end] => 17.00
                    [description_1] => tooltip Tectum
                    [description_2] => Vrijdag 18 Oktober
                    [event_title] => ?
                    [column_title] => Tectum
                    [booking_count] => 4
                    [available_places] => 150
                    [slots_per_user] => 30
                    [current_user_booking_count] => 0
                    [current_guest_booking_count] => 0
                )

        )

Answer 1

您应该使用数组。 $array[]表示追加到数组。看来TT_DB::getEventHours返回了一个对象数组。我在以下代码中考虑了这一点。

$workshop_ids = explode(',', $event_hour_id);

$event_hour_details_array = array();
foreach ($workshop_ids as $workshop_id){
    $event_hour_details_array[] = TT_DB::getEventHours(array(
        'event_hours_id' => $workshop_id,
        'user_id' => $user_id,
        ));
}

//for debugging
echo "<pre>".print_r($event_hour_details_array, true)."</pre>";

foreach($event_hour_details_array as $event_hour_details) {
    foreach($event_hour_details as $hours) {
        echo $hours->column_title." ".$hours->start."-".$hours->end."<br>";
    }
}

请尝试这样做，可能会对您有所帮助： $ data = []; foreach（$ workshop_ids为$ workshop_id）{ $ abc [] = array（ 'name_your_column'=> workshop_id 'name_your_column'=> workshop_id ） }

如何从数组中的数组中获取价值？
