Right now I have the following array inside each of my controllers but now I decided that I want to include some more variables in the array which means that I have to edit each controller .

Do you know a way that I can put this array in a file or something and include it inside each controller?

Apologies in advance for my newbie question - totally new to CodeIgniter.

In most Object-Oriented frameworks that use the MVC pattern, data validation is handled by the MODEL classes. That seems to be the logical division, as the model should be aware of what is, and isn't, permissible in its variables. A view, or a controller, would only be able to do very basic validation - ie., "is this an email address", "is this a number", etc. - but by the very definition on OO, it will be the model class that will be responsible for doing the ultimate check on the data, and making sure that it can be stored in the database. Even if we consider database operations alone - ie., referential integrity checks, etc. - there is a lot of validation that can only (and should only) be performed by the model. If the model *will* have to perform *some* data validation, then it does not seem to make much sense to put any data validation in a control class, and even less in a view class, as these then would have to be aware of the internal functioning and requirements of the model - and that breaks encapsulation, and makes it meaningless to have an OO framework in the first place.

Indeed, so far, every OO framework I've used instructs programmers to place data validation functions within the model classes.

It seems to me, however, from the information in the User Guide, and from several postings in this forum, that CodeIgniter assumes that data validation for my models should be performed by my CONTROLLER classes - using the Form Validation class. Am I wrong?

Is there an easy way to implement the data validation functions - already available in the Form Validation class - in my models?

Hi all,

After having implemented Zend_ACL in my codeigniter application, I am looking to serialize the ACL object and cache it to cut down on the various overheads that can create as it gets bigger.

My question is, is there any benefit in using the Zend_Cache libraries to do this, over just using the PHP serialize function and using CodeIgniter's file helper to store it in a file. I can then use the CI file helpers to pull it out of the file and unserialize it.

Thanks for the help.

Hello,

I'm curious how I would setup my server to use dynamic subdomains. I have full access to http.conf, and the entire server. I want to acheive the effect of WordPress MU, if you know how that works.

The site I'm creating allows people to create blog-like sites under my parent domain, so it would be http://sample.mydomain.com/. The domain would then route to a URL such as:

I am trying to use readfile (or CI read_file) to load an image from the server and output it to the browser. What is really strange is that if I watch my logs I see two requests happening right after each other every time it runs.

This is what I am running:

// Shows the image, but two requests show up in system logs
header('Content-type: '.$file['mime']);
readfile($load_path);

// Outputs binary data to browser
$this->output->set_header('Content-type: '.$file['mime']);
readfile($load_path);

// Doesn't work
$this->output->set_header('Content-type: '.$file['mime']);
return read_file($load_path);

Any idea what might be going on?

Hello,
Can someone share a regex that properly handles grabbing a http link from a string of text?
What I have below works, but not in all circumstances, i.e. link has ),>,:, etc on the end. So I would love to know people's experiences with this and how they solved it.

Thanks!

Using CodeIgniter, I am building constants within a function for a navigation image. For some reason what works in one function does not work in another.

I have defined two constants: one for a logo image to display in a banner and one for a navigation image to display just below the banner.

Is it possible to resize AND crop with the same request?

I am passing in these configuration values:

[width] => 200
[height] => 200
[x_axis] => -150
[y_axis] => 0


I am calculating the x axis myself given the size of the image, and the size I would like to output. The intention is that it would resize the image to fit the size I specify and crop off the ends that hang off. That way I can resize to an exact dimension an not have empty space.

Does not seem to work thou.

I am trying to get the force_download function to work with AJAX, or even just with direct headers and I am unable to get it to work. The force_download works fine without using AJAX request.

Does anyone have any advice on how to go about using AJAX for a forced download? I have seen a couple topics but am unable to get anything working, thanks!
