【问题描述】:
我正在运行 PHP 版本 5.2.11
当我运行下面的函数时:
function get_dirs($path = '.') {
$dirs = array();
foreach (new DirectoryIterator($path) as $file) { // This is line 462.
if ($file->isDir() && !$file->isDot()) {
$dirs[] = $file->getFilename();
}
}
return $dirs;
}
我得到这个错误:
Fatal error: Uncaught exception 'RuntimeException' with message 'DirectoryIterator::__construct(/home/test/test.com/wp-content/themes/mytheme/images) [<a href='directoryiterator.--construct'>directoryiterator.--construct</a>]: failed to open dir: No such file or directory' in /home/test/test.com/testing123/wp-content/themes/mytheme/functions.php:462 Stack trace: #0 /home/test/test.com/testing123/wp-content/themes/mytheme/functions.php(462): DirectoryIterator->__construct('/home/test/wie...') #1 /home/test/test.com/testing123/wp-content/themes/mytheme/functions.php(31): get_dirs('/home/test/wie...') #2 /home/test/test.com/testing123/wp-settings.php(717): include('/home/test/wie...') #3 /home/test/test.com/testing123/wp-config.php(76): require_once('/home/test/wie...') #4 /home/test/test.com/testing123/wp-load.php(30): require_once('/home/test/wie...') #5 /home/test/test.com/testing123 in /home/test/test.com/testing123/wp-content/themes/mytheme/functions.php on line 462
更新:我发现这里的问题是主题安装在主 URL 之外的虚拟目录下。我的脚本期望主题安装在主根 url 之外。
例如本案例中的主题安装在:http://www.example.com/testing123/wp-content/themes/mytheme
但是,我期待这个:http://www.example.com/wp-content/themes/mytheme
还有……
我的路径功能失败,因为它没有考虑到它可以安装在虚拟目录下。
我如何在提供此功能时考虑这种情况?
$mydir = get_dirs("$_SERVER[DOCUMENT_ROOT]/wp-content/themes/mytheme/images");
function get_dirs ($path = '.') {
$dirs = array();
foreach (new DirectoryIterator($path) as $file) {
if ($file->isDir() && !$file->isDot()) {
$dirs[] = $file->getFilename();
}
}
return $dirs;
}
【问题讨论】:
-
如果显示无法打开您的图像目录,您认为错误是在编码中吗?
-
呃……好像找不到目录,实例化DirectoryIterator没问题。
