PHP：通过php生成的ics文件中的多个事件？

标签： php mysql

我使用php生成ics文件，只要ics文件中只包含一个事件，一切正常。

但是，我试图将多个事件放在同一个ics文件中。

我使用存储在MYSQL中的信息来生成ics文件。

我遇到的问题是，当我运行我的代码时，我没有任何错误，但是没有生成任何ics文件！

这是我的全部代码：

<?php
class ICS {
    var $data;
    var $name;
    function ICS($start,$end,$name,$description,$location) {
        $this->name = $name;
        $this->data = "BEGIN:VCALENDAR\nVERSION:2.0\nMETHOD:PUBLISH\nBEGIN:VEVENT\nDTSTART:".date("Ymd\THis\Z",strtotime($start))."\nDTEND:".date("Ymd\THis\Z",strtotime($end))."\nLOCATION:".$location."\nTRANSP: OPAQUE\nSEQUENCE:0\nUID:\nDTSTAMP:".date("Ymd\THis\Z")."\nSUMMARY:".$name."\nDESCRIPTION:".$description."\nPRIORITY:1\nCLASS:PUBLIC\nBEGIN:VALARM\nTRIGGER:-PT10080M\nACTION:DISPLAY\nDESCRIPTION:Reminder\nEND:VALARM\nEND:VEVENT\nEND:VCALENDAR\n";
    }
    function save() {
        file_put_contents($this->name.".ics",$this->data);
    }
    function show() {
        header("Content-type:text/calendar");
        header('Content-Disposition: attachment; filename="'.$this->name.'.ics"');
        Header('Content-Length: '.strlen($this->data));
        Header('Connection: close');
        echo $this->data;
    }
}
?>


<?php
    $sql = "SELECT * FROM mytable" ; 
    // ------- MAKE SURE PERSON EXISTS IN DATABASE ---------
    $query = mysqli_query($db_conx, $sql);
    $existCount = mysqli_num_rows($query); // count the row nums
    if ($existCount == 1) { // evaluate the count
         while($row = mysqli_fetch_array($query, MYSQLI_ASSOC)){ 
             $id = $row["id"];
             $details = $row["details"];
             $location = $row["location"];
             $start_date = $row["start_date"];
             $end_date = $row["end_date"];
             $title = $row["title"];

             $start0 = str_replace("/","-",$start_date);
             $end0 = str_replace("/","-",$end_date);

            /* $start_date = date("Y-m-d H:i");*/


            $end_date = strtotime($end_date . ' -1 hour');
            $end_date = (date('Y-m-d H:i', $end_date));

            $start_date = strtotime($start_date . ' -1 hour');
            $start_date = (date('Y-m-d H:i', $start_date));


           $event .= new ICS("".$start_date."","".$end_date."","".$title."","".$details."","".$location."");
           $event->show();




         }
    } 
?>

如果我删除这行代码并将其放在我的while循环之外，那么everrything会再次起作用，但它会生成一个只有1个事件的ics文件！

       $event = new ICS("".$start_date."","".$end_date."","".$title."","".$details."","".$location."");
       $event->show();

有人可以就此问题提出建议吗？

提前致谢。

编辑：

我现在已经创建了ics文件，但它不会导入到日历中，当我尝试在日历中添加事件时出现失败错误：

<?php
class ICS {
    var $data;
    var $name;
    function ICS($start,$end,$name,$description,$location) {
        $this->name = $name;
        $this->data = "BEGIN:VCALENDAR\nVERSION:2.0\nMETHOD:PUBLISH\nBEGIN:VEVENT\nDTSTART:".date("Ymd\THis\Z",strtotime($start))."\nDTEND:".date("Ymd\THis\Z",strtotime($end))."\nLOCATION:".$location."\nTRANSP: OPAQUE\nSEQUENCE:0\nUID:\nDTSTAMP:".date("Ymd\THis\Z")."\nSUMMARY:".$name."\nDESCRIPTION:".$description."\nPRIORITY:1\nCLASS:PUBLIC\nBEGIN:VALARM\nTRIGGER:-PT10080M\nACTION:DISPLAY\nDESCRIPTION:Reminder\nEND:VALARM\nEND:VEVENT\nEND:VCALENDAR\n";
    }
    function save() {
        file_put_contents($this->name.".ics",$this->data);
    }
    function show() {


        echo $this->data;
    }
}


header("Content-type:text/calendar");
header('Content-Disposition: attachment; filename="test.ics"');
Header('Content-Length: '.strlen($this->data));
?>
<?php
    $sql = "SELECT * FROM mytable"; 
    // ------- MAKE SURE PERSON EXISTS IN DATABASE ---------
    $query = mysqli_query($db_conx, $sql);
    $existCount = mysqli_num_rows($query); // count the row nums
    if ($existCount == 1) { // evaluate the count
         while($row = mysqli_fetch_array($query, MYSQLI_ASSOC)){ 
             $id = $row["id"];
             $details = $row["details"];
             $location = $row["location"];
             $start_date = $row["start_date"];
             $end_date = $row["end_date"];
             $title = $row["title"];

             $start0 = str_replace("/","-",$start_date);
             $end0 = str_replace("/","-",$end_date);

            /* $start_date = date("Y-m-d H:i");*/


            $end_date = strtotime($end_date . ' -1 hour');
            $end_date = (date('Y-m-d H:i', $end_date));

            $start_date = strtotime($start_date . ' -1 hour');
            $start_date = (date('Y-m-d H:i', $start_date));


           $event .= new ICS("".$start_date."","".$end_date."","".$title."","".$details."","".$location."");





         }
    }

$event->show(); 

Header('Connection: close');
?>

第二次编辑：

根据下面给出的答案，我已经将我的代码更改为这样，但这根本不会创建任何ics文件，也没有错误：

<?php
date_default_timezone_set("Europe/London");
class ICS {
    private $event;
    private $name;

    function addEvent($start, $end, $name, $description, $location) {
        $this->name = $name;
        $this->event .= "BEGIN:VEVENT\nDTSTART:".date("Ymd\THis\Z",strtotime($start))."\nDTEND:".date("Ymd\THis\Z",strtotime($end))."\nLOCATION:".$location."\nTRANSP: OPAQUE\nSEQUENCE:0\nUID:\nDTSTAMP:".date("Ymd\THis\Z")."\nSUMMARY:".$name."\nDESCRIPTION:".$description."\nPRIORITY:1\nCLASS:PUBLIC\nBEGIN:VALARM\nTRIGGER:-PT10080M\nACTION:DISPLAY\nDESCRIPTION:Reminder\nEND:VALARM\nEND:VEVENT\n";
    }

    function output() {

        if ($this->event) {
           header("Content-type:text/calendar");
           header('Content-Disposition: attachment; filename="'.$this->name.'.ics"');
           Header('Content-Length: '.strlen($this->event));

           echo "BEGIN:VCALENDAR\nVERSION:2.0\nMETHOD:PUBLISH\n".$this->event."END:VCALENDAR\n";

           Header('Connection: close');
        }
    }
}
?>
<?php
$event = new ICS;

    $sql = "SELECT * FROM mytable"; 
    // ------- MAKE SURE PERSON EXISTS IN DATABASE ---------
    $query = mysqli_query($db_conx, $sql);
    $existCount = mysqli_num_rows($query); // count the row nums
    if ($existCount == 1) { // evaluate the count
         while($row = mysqli_fetch_array($query, MYSQLI_ASSOC)){ 
             $id = $row["id"];
             $details = $row["details"];
             $location = $row["location"];
             $start_date = $row["start_date"];
             $end_date = $row["end_date"];
             $title = $row["title"];

             $start0 = str_replace("/","-",$start_date);
             $end0 = str_replace("/","-",$end_date);

            /* $start_date = date("Y-m-d H:i");*/


            $end_date = strtotime($end_date . ' -1 hour');
            $end_date = (date('Y-m-d H:i', $end_date));

            $start_date = strtotime($start_date . ' -1 hour');
            $start_date = (date('Y-m-d H:i', $start_date));


           $event->addEvent($start_date,$end_date,$title,$details,$location);





         }

    }

    $event->output();

?>

第三次编辑

好吧，看起来我到了某个地方......我已经将我的代码更改为以下内容，当我运行我的php页面时，我得到了test.ics文件，但是当我打开它时，它是空的。它什么都没有！

<?php
class ICS {
    var $data;
    var $name ='test';
    function addEvent($start, $end, $name, $description, $location) {
        $this->name = $name;
        $this->event .= "BEGIN:VEVENT\nDTSTART:".date("Ymd\THis\Z",strtotime($start))."\nDTEND:".date("Ymd\THis\Z",strtotime($end))."\nLOCATION:".$location."\nTRANSP: OPAQUE\nSEQUENCE:0\nUID:\nDTSTAMP:".date("Ymd\THis\Z")."\nSUMMARY:".$name."\nDESCRIPTION:".$description."\nPRIORITY:1\nCLASS:PUBLIC\nBEGIN:VALARM\nTRIGGER:-PT10080M\nACTION:DISPLAY\nDESCRIPTION:Reminder\nEND:VALARM\nEND:VEVENT\n";
    }

    function save() {
        file_put_contents($this->name.".ics",$this->data);
    }
    function show() {
        header("Content-type:text/calendar");
        header('Content-Disposition: attachment; filename=test.ics');
        Header('Content-Length: '.strlen($this->data));

        //echo $this->data;
        echo "BEGIN:VCALENDAR\nVERSION:2.0\nMETHOD:PUBLISH\n".$this->data."END:VCALENDAR\n";

        Header('Connection: close');
    }
}
?>
<?php
$event = new ICS;

    $sql = "SELECT * FROM mytable" ; 
    // ------- MAKE SURE PERSON EXISTS IN DATABASE ---------
    $query = mysqli_query($db_conx, $sql);
    $existCount = mysqli_num_rows($query); // count the row nums
    if ($existCount == 1) { // evaluate the count

         while($row = mysqli_fetch_array($query, MYSQLI_ASSOC)){ 
             $id = $row["id"];
             $details = $row["details"];
             $location = $row["location"];
             $start_date = $row["start_date"];
             $end_date = $row["end_date"];
             $title = $row["title"];

             $start0 = str_replace("/","-",$start_date);
             $end0 = str_replace("/","-",$end_date);

            /* $start_date = date("Y-m-d H:i");*/


            $end_date = strtotime($end_date . ' -1 hour');
            $end_date = (date('Y-m-d H:i', $end_date));

            $start_date = strtotime($start_date . ' -1 hour');
            $start_date = (date('Y-m-d H:i', $start_date));

            $event->addEvent("".$start_date."","".$end_date."","".$title."","".$details."","".$location."");



         }

    } 

 $event->show();


?>
