【问题描述】：
我对 stackoverflow 完全陌生。我正在尝试调整一个现有脚本，其中包含照片和视频的文件夹正在加载并像幻灯片一样显示。
我还想添加加载网页的选项。有什么简单的方法吗？
非常感谢。 这是我的代码：
<?php
include "class.getFiles.php";
$images = new getFiles();
// list of all files in the images folder (includes videos)
$imageArray = $images->getImageArray();
$sortedImages = new sortFiles();
$sortedImages->sortImageArray($imageArray);
// remove files not in the correct time period
$imageArray = $sortedImages->getImageArray();
$randImage = $sortedImages->randomImageNum();
$fileName = $imageArray[$randImage];
$info = new SplFileInfo($fileName);
?>
<!DOCTYPE html>
<html>
<head>
<title>Fiction Slideshow</title>
<link rel="stylesheet" type="text/css" href="main.css">
</head>
<body>
<?php
if($info->getExtension() == "mp4")
{
echo '<video id="vid" class="videoDisplay" autoplay>
<source src="images/'.$fileName.'" type="video/mp4">
Your browser does not support the video tag.
</video>';
echo '<script type="text/javascript">
var vid = document.getElementById("vid");
vid.addEventListener("ended", function(){
window.location.reload();
});
</script>';
}
else
{
echo '<img class="imageDisplay" src="images/'.$fileName.'" />';
echo '<script type="text/javascript">
setTimeout(function(){
window.location.reload();
}, 30000);
</script>';
}
?>
</body>
</html>
这是其他脚本调用的 class.getFiles.php 文件。
<?php
类 getFiles{
protected $dir;
protected $imageArray;
function __construct()
{
$this->get_dir();
$this->get_images();
}
protected function get_dir()
{
$this->dir = getcwd();
}
protected function get_images()
{
if(count(scandir($this->dir."/images")) != 2)
{
$this->imageArray = scandir($this->dir."/images");
}
else
{
die("There are no files in the directory");
}
}
public function getImageArray()
{
return $this->imageArray;
}
}
类排序文件{
protected $sortedImageArray = [];
public function sortImageArray($imageArray)
{
foreach ($imageArray as $imageFile )
{
if($imageFile !== ".." && $imageFile !== ".")
{
$imagePath = $imageFile;
$imageFile = (substr($imageFile, 0, -4));
$BeginningPos = strpos($imageFile, '_');
$beginningDate = (substr($imageFile, 0, $BeginningPos));
$beginningDateformatted = str_replace("-","/", $beginningDate);
$stringToStartTime = strtotime($beginningDateformatted);
$EndingPos = strpos($imageFile, '_', $BeginningPos + strlen('_'));
$EndingPos = $EndingPos + 1;
$EndingDate = (substr($imageFile, $EndingPos));
$EndingDateformatted = str_replace("-","/", $EndingDate);
$stringToEndTime = strtotime($EndingDateformatted);
$time = time();
if($time <= $stringToStartTime && $time >= $stringToEndTime)
{
array_push($this->sortedImageArray, $imagePath);
}
}
}
}
public function getImageArray()
{
if(count($this->sortedImageArray) != 0)
{
return $this->sortedImageArray;
}
else
{
die("There are no files in the time range");
}
}
public function randomImageNum()
{
$imageArrayLength = count($this->sortedImageArray);
$imageRand = rand(0, $imageArrayLength-1);
return $imageRand;
}
}
?>
