Question

I’ve been struggling with 2 problems when creating a CMS where I want to implement friendly urls, using PHP5 and MySQL 5.

The basic database structure is as follows:

-------------------------------
| ID    | PageName | ParentID |
-------------------------------
| 1 | Page1        | 0        |
| 2 | Page2        | 0        |
| 3 | SubPage1     | 1        |
| 4 | SubSubPage1  | 3        |
-------------------------------

I then want to generate urls like the following:

Page with ID=1 will have URL: /Page1
Page with ID=3 will have URL: /Page1/SubPage1
Page with ID=4 will have URL: /Page1/SubPage1/SubSubPage1

When visiting the page I have a .htaccess rule to dispatch the url to a querystring like: ?page=/Page1/SubPage1 etc

How can I query the database to compare the URL with the database entries?

Answer 1

Say your route is /Page1/SubPage1/SubSubPage1, your query would be:

SELECT p1.id
    FROM pages AS p1, pages AS p2, pages AS p3
    WHERE p1.PageName = 'SubSubPage1' AND p1.parentID = p2.ID AND
          p2.PageName = 'SubPage1' AND p2.parentID = p3.ID AND
          p3.PageName = 'Page1'
