n00bz question

Hey all

New to CodeIgniter. I have what I think is a pretty simple question (and presumably has a pretty simple answer).

Let's say I have a page that displays comments. Underneath the comments I have a link that says, 'Add a comment.' When that link is clicked, I want to show the comment form (duh!).

If I were writing PHP from scratch, I could add a query string to the link like so:

Code:

<a href="foo.php?add_comment=yes">add a comment!</a>

I could then read that value using $_GET or $_REQUEST. How can I set that link to be CI friendly so I can use the uri class?

CodeIgniter doesn't use $_GET what you have instead is a controller that handles a certain type of page. for example :

http://yourdomain.com/controller/method/variable

in your controller you will have a method

function method(variable) {
}

hope this helps, if not, then I would recommend doing the build a blog in 15 minutes tutorial

Yep, that video tutorial is great for getting your head around the idea of how the URI's work. You don't really have to deal with ?function=dothis

Yep I watched over the tutorial. I think my question is more about the view file. My view file contains both the form and the comments, but I only want to display the comment form when the user clicks the 'Add a comment' link. I realize this could easily be done with JavaScript, but I am simply experimenting with CI to get my head around how it works.

[eluser]indocoder[/eluser]
if you using the global "view" file , use the IF ELSE statement inside the view for each method but I really not recommend this as a good solution for a beginner.

[eluser]NateL[/eluser]
OH! Sorry..

For that, I don't think you would need PHP at all. just jQuery.

Perfect tutorial for you:

Ah yes, but as I mentioned I was trying to set it up without javascript - that I know I could do easily I just wanted to test out how to do stuff with CI.

Here is what the full page would look like, we'll call it index.php:

Code:

<ol>
    <li>
        First Comment
    </li>
    <li>
        Second Comment
    </li>
</ol>

<p><a href="index.php?add_comment=yes">Add a comment</a></p>

&lt;?php if (isset($_REQUEST['add_comment']) && $_REQUEST['add_comment'] == 'yes') : ?&gt;
    
    &lt;form action="#" method="post" accept-charset="utf-8"&gt;
        &lt;input type="text" name="email" value="" id="email" /&gt;
        &lt;textarea name="comment" rows="8" cols="40"&gt;&lt;/textarea>
        <p>&lt;input type="submit" value="Continue &rarr;" /&gt;&lt;/p>
    &lt;/form&gt;

&lt;?php endif; ?&gt;

I suppose I could create two separate views, but that seems wasteful. I think I need to pass in variable via the controller, yes?
