我正在为学校做一个项目,我第一次使用laravel框架。我遇到了一个小问题,我已经卡了好几天,尝试了很多不同的方法 - 没有任何效果。
我构建了一个时间函数,它将接受多个参数,然后检查 db 通过 while 循环,然后将所有结果添加到"全局"数组中,然后另一个函数将测试该全局数组并检查其中的值。
我遇到的问题是我无法让函数正确访问全局数组:
我在网上尝试了很多不同的想法,但无法让类的内部函数访问全局数组 -
有谁知道一个简单的方法怎么做? 谢谢
尝试过(在最顶端 - 在课堂之前,也在班级内部在顶部)
$Global['ScheduleTest'] = array();
global $ScheduleCheck = array();
(inside class ) private $ScheduleCheck = array();
完整代码
:::::::<?php
global $ScheduleCheck = array() ;
class CourseRegistrationController extends BaseController {
public function __construct() {
$this->beforeFilter('csrf', array('on'=>'post'));
}
.....
// Function to test time overlaps
function testTimeOverlap($course ,$regday, $start_time,$end_time)
{
$start_time1 = (substr($start_time, 0, 5)) ;
$end_time1 = (substr($end_time, 0, 5)) ;
$ScheduleArr = makeSchedule();
$reg_days = explode(",",$regday);
foreach ($reg_days as $rday)
{
foreach ($ScheduleArr as $schedule)
{
if((strtolower($rday))==(strtolower($schedule['day'])))
{
$start_time2 = (substr($schedule['stime'], 0, 5)) ;
$end_time2 = (substr($schedule['etime'], 0, 5)) ;
if(testTime($start_time1,$end_time1,$start_time2,$end_time2))
{
array_push($ScheduleCheck, array("course"=>$course,"value"=>"true","day"=>$rday ));
}
else
{
array_push($ScheduleCheck, array("course"=>$course,"value"=>"false","day"=>$rday ));
}
}
else
{
array_push($ScheduleCheck, array("course"=>$course,"value"=>"true","day"=>$rday ));
}
}
}
}
// Another function to go through the global array
function finalTimeTest()
{
testNewTime((strtolower(Input::get('course_id'))),(strtolower(Input::get('lecture_id'))),(strtolower(Input::get('tutorial_id'))),(strtolower(Input::get('lab_id'))));
foreach($ScheduleCheck as $ckTime)
{
if($ckTime['value']=="true")
{
return true;
}
else
{
return ($ckTime['course']." ");
}
}
}
?>
这些"函数"应该定义为类上的方法。
class ScheduleChecker {
protected $scheduleCheck = array();
// Your functions should be placed in here!
public function getScheduleCheck()
{
return $this->scheduleCheck;
}
}
然后,可以从方法内部引用该属性。
public function finalTimeTest()
{
// Using $this to call the testNewTime method.
$this->testNewTime((strtolower(Input::get('course_id'))),(strtolower(Input::get('lecture_id'))),(strtolower(Input::get('tutorial_id'))),(strtolower(Input::get('lab_id'))));
// Using $this to get the scheduleCheck property.
foreach($this->scheduleCheck as $ckTime)
{
if($ckTime['value']=="true")
{
return true;
}
else
{
return ($ckTime['course']." ");
}
}
}
您可能希望将其绑定到 Laravel 的容器(app/start/global.php
):
App::instance('schedule', new ScheduleChecker);
然后,在控制器中获取 $scheduleCheck
属性:
$scheduleCheck = App::make('schedule')->getScheduleCheck();
