[英]how to show files from directory and all subdirectories?
I'm working on my photo gallery when user can upload photos and also choose a category.当用户可以上传照片并选择类别时,我正在处理我的照片库。 My categories are subdirectories in images/
.我的类别是images/
中的子目录。 When user doesn't choose a category then photos are stored in images/
.当用户不选择类别时,照片将存储在images/
中。 I want to display all photos (from all categories and other) in gallery but now I manage to show only these without category.我想在图库中显示所有照片(来自所有类别和其他),但现在我设法只显示这些没有类别的照片。 Can someone help me?有人能帮我吗? Here's fragment of my php code这是我的 php 代码的片段
$fo=opendir("images");
if ($dh = opendir("images")){
$count = 1;
while($file=readdir($fo)){
if($file!="" && $file!="." && $file!=".."){
$image_path = "images/".$file;
if(!is_dir($image_path)){
?>
<div class="gallery">
<a href="<?= $image_path; ?>">
<img src="<?= $image_path; ?>">
I tried to list all subdirectories我试图列出所有子目录
$directories = glob("images" . '/*' , GLOB_ONLYDIR);
but I don't know what to do next但我不知道下一步该怎么做
You should use a RecursiveDirectoryIterator, see https://www.php.net/manual/en/class.recursivedirectoryiterator.php您应该使用 RecursiveDirectoryIterator,请参阅https://www.php.net/manual/en/class.recursivedirectoryiterator.php
You could then do something like:然后,您可以执行以下操作:
$folder = "path to your folder";
$files = new RecursiveIteratorIterator(
new RecursiveDirectoryIterator($folder, RecursiveDirectoryIterator::SKIP_DOTS),
RecursiveIteratorIterator::CHILD_FIRST
);
foreach ($files as $fileinfo) {
// fileinfo is an object, see documentation for info
$path = $fileinfo->getRealPath();
}
