How to execute php code selected from a database

adaykin

I have a base url variable that is defining the root url of my site. (I am using CodeIngiter)

The way I normally do URL's on my site is:

<a href='<?php echo URL?>linkhere.php'>Link</a>

But when I pull the same code pasted above from a database, the php code does not get evaluated.

Aside from using eval, how can I achieve the same thing that I am doing on my pages?

From your description, I'm assuming what you store in the db is something like

id		url
1		<?php echo someurl?>

Why not just

id		url
1		someurl

<a href='<?php echo $row['url']; ?>

URL is a constant that gets defined in my config file, all it is is the base url, e.g. http://google.com instead of http://google.com/afterthebaseurl.

So the base url is really just the domain.

I still don't get the point of storing php code in the db.

define('URL', 'http://domain.topdomain');

// ...

<a href="<?php echo URL . $row['url']; ?>"
[/php

the code is stored in the database because in the cms part of the application the user is entering in url's, and the content will change so it needs to be dynamic.

Exactly what are you saying? Exactly what is stored in the db. Exactly what is entered by the user?

This is my last guess... In the db, you actually store

<?php echo $url ?>

And then somewhere before you retrieve and display that data, you take user input and assign it to $url.

It still makes no sense to me. What are you trying to achieve?

its not suggested to allow php codes from user inputs!

eval() in php could do that.
