Question

DEFINE ('PAGES', '/pages/');
$directory_pages = new DirectoryIterator(PAGES); //ERROR LINE
foreach ($directory_pages as $files) {
    if ($files_pages->isFile()) {
        $file_name_page = $files_pages->getFilename();
        $my_page_content = file_get_contents(PAGES. $file_name_page);
    }
}

This code is located in a plugin, where the “pages” folder that I’m trying to access is inside the plugin itself.

So the script is myplugin.php and it resides in the folder “myplugin”, which has a subfolder, “pages”.

I’m trying to load the files in the “pages” directory, but my path reference is throwing an error. Do I need to use ABSPATH here instead?

Or perhaps a dynamic method to get the current directory relative to root of WordPress?

Answer 1

The manual says:

Throws an UnexpectedValueException if the path cannot be opened.

Basically, if /pages is not a valid directory, then it won’t work. To be relative to the current working directory you would use pages without the leading slash.

I’m not familiar with WordPress, but if it supplies a valid base constant prefix to use, then I would prepend that to the path you are using.
