Hello,

I am trying to understand how the modular development works, i ve seen some projects that allow CI apps to use modules in order to extend the application, but i am trying to understand how it works.. At the moment it seems like it is all about routing...? am i correct...?

Is there any information that i could get or links that would help me understand how it works...?

Any info would be appreciated...

Thanks...

Greetings all,

I am rather new to Javascript and Ajax, try as I might to hold onto the server side past I am starting to fall to the Dark Side.

What I am attempting to do is write a validation library for a data gathering application, validate as much data on the client side before submission, thus reduce the number of "opps" page loads. Problem is as it got more complicated it stopped working. Here's what I need to do.

1) Once a form is loaded each field will run a validateField() function to validate it's own data for completion and proper format.

2) When the user clicks the submit button the function validateForm() will run and if there are no errors the form will submit itself, otherwise it will return a message that data was not complete ( which should almost, if ever, happen ).

Now, #1 is trickier than it sounds... My intention is to use the class tag to determine the validations that would run on a particular field ( class="required email" etc), thus allowing me to use addClassName to add additional validations for a field on the fly ( e.g. the value of item #1 means that now there must be a value entered for item #5 & #6, I merely addClassName('required') to the respective items ).

Here is the widget I have thusfar:

Hi everyone.

I have a form with custom validation. Basically, it makes sure that the name of a group is unique by looking up the name before trying to insert the record (via "callback_XYZ" feature of CI validation). On FF3, it works fine.. but in IE7, it looks like the form is submitting TWICE (with single form submit "click") b/c the record is added on the DB (i made sure the table is empty) and validation comes back saying that the name is taken.

From this my only guess is that IE7 is somehow submitting twice.
IS there a solution to this? It's making me pull my hair out! :/

Hi,

I started with the Flexigrid and so far it is excellent. I do have a question.

I have a json grid based on a Java servlet and it works great. I am planning to have some dropdowns, textboxes that will have search criteria. How can I send them as some [name, value] parameter to my url?

Tried to get the url to modify and reload, can't see how to go about it.

A simple code example would be a great help!


Thanks,
Kal

Hello all!

Sorry to give a disclaimer right off the bat, but I am still working at getting my feet wet with this CI stuff. So please be patient with me!

I am building an application that will be used to register individuals for a particular event. So far I have the forms built, passing the data to my database, and emailing me the results. What I need to do now is implement a PayPal payment gateway. Ideally the payment would happen prior to sending me the email and posting to the database. I'm sure this will entail IPN...

Can someone please give me some general direction as to how to make this happen?

Thanks in advance.

Jesse

PS - I am fairly active in the ExpressionEngine forums, and hoping that the CI forums will be a positive experience :cheese:

I finally did it, my first CodeIgniter based site, http://www.UnderGroundLyricSearch.com

I want to say thank you to all the people that made posts that contributed to me get this project off the ground. This site is a great resource, and makes CI rock that much harder.

I honestly can't think of writing php code outside of CI now.

I'm having an issue with the autoload.php file not being used when an undefined Controller is given. The same issue has been reported here, but I felt as thought it was better suited for this discussion. Is there a possible workaround for this, or perhaps a way of having a custom controller for our error pages? Thanks.
