Question

I have a question that I haven’t been able to find the answer/script to. I’m just learning to use PHP. I’m using Perch as a CMS and has been going great so far.

I’ve run into a snag when it comes to adding new pages. Something that I want PHP to do is be able to create a dynamic navigation menu for only that directory.

For example, I have three pages in my ‘about’ directory.

root
/about
/index.php
- page2.php
- page3.php

I want to be able to output a side navigation menu based off only that directory.

Home - Page2 - Page3

And when the client/user creates a new page, it’ll automatically add it to the list. So…

root /about /index.php - page2.php - page3.php - newPage.php

…creates…

Home - Page2 - Page3 - New Page

Can anyone point me into a direction of a script or help me get started?

Thanks!

Answer 1

There are quite a few php functions to iterate through directories. I think the cleanest is using PHP SPL (Standard PHP Library)’s Directory Iterator.

http://www.php.net/manual/en/class.directoryiterator.php

$dir = new DirectoryIterator('about');
foreach ($dir as $fileinfo) {
    if (!$fileinfo->isDot()) {
        // Can make the link here
        echo $fileinfo->getFilename();
    }
}

The advantage is you have a lot of class functions available to you.

If you need more than the filename you can use:

• getPathname()
• getPath()
• getBasename()
• isDir()

And so on… see the docs for all the possibilities.
