prefix . 'booking_timeslots';   
    $timeslots = $_POST['timeslot'];
       foreach ($timeslots as $time) {
          echo $dd = $time['timeslot'];
       }
}
?>

这是我的完整查询代码。

prefix . 'booking_dates';   //'booking_dates' is a table name which is in the database
    $booking_timeslots = $wpdb->prefix . 'booking_timeslots';   //'booking_timeslots' is a table name which is in the database

    $year = $_POST['year'];
    $month = $_POST['month'];
    $days = $_POST['days'];
    $timeslots = $_POST['timeslot'];

        $data['year'] = $year;      // $data['year'] year is a name of column in database
        $data['month'] = $month;
    foreach ($days as $day) {           // $data['month'] month is a name of column in database
        $data['day'] = $day;            // $data['day'] day is a name of column in database

        $wpdb->insert($booking_dates,$data);
        $last_record_id = $wpdb->insert_id;

        foreach ($timeslots as $timeslot) {
            $data_timeslot['bid'] = $last_record_id;
            $data_timeslot['time'] = $timeslot;
            $wpdb->insert($booking_timeslots,$data_timeslot);
        }
    }
}
?>

当上面的代码执行时，wordpress会给出以下错误。

Illegal string offset 'timeslot' 

有人能帮我解决这个问题吗。

Answer 1

获得illegal string offset 'timeslot' 是因为 $time is不是数组，而是数组 $timeslots中的一个项。您已经检索了使用$timeslots = $_POST['timeslot'];提交的值。

您的代码还包含其他类型错误。以下是更正后的代码：

      3
   
   


prefix . 'booking_timeslots';   
    $timeslots = $_POST['timeslot'];
    // you can use print_r() here 
    print_r( $timeslots );  // to see what is submitted from form

    foreach ($timeslots as $time) {
          echo $time;
    }
}
?>

我希望这能帮到你。
