How to in one method add many views ?

Code:
public function active()

    {

        $this->load->model('survey_model');

        $this->load->library('auth');

        $this->data = array('survey' =>  $this->survey_model->loadPublished($this->auth->getUser()->userId));

        $this->load->library('design');

        $this->design->header('header_logged');

                //one view i need 4

        $this->load->view('/survey/active',$this->data);

        $this->design->footer('footer_logged');

    }

Resetting class variables to defaults

I start my models with..

Code:
&lt;?php

class x_model extends Model {

    // Table name

    var $table = '';

    // Order field name

    var $order_field = array();

    // Limit and offset

    var $limit = NULL;

    var $offset = NULL;

    // Field names in the database table

    var $id = NULL;

    var $name = NULL;

    // etc...

... and then I have a reset() function that looks like this...

Code:
function reset()

    {

        // Ensure all the variables are listed here

        $this->id = NULL;

        $this->name = NULL;

        // etc...

        $this->limit = NULL;

        $this->offset = NULL;

        $this->order_field = array();

    }

Instead of listing out all the variables again with their defaults, is there a shorthand which just sets the variables back to their original values?

Many thanks,

Dan.

	[eluser]meglio[/eluser] Is it possible?

meta() function not documented.

Hi all, I have seen in html_helper that there is a new feature that is not documented, but it is very useful, at least for me, the function is this:

Code:
// ------------------------------------------------------------------------

/**

 * Generates meta tags from an array of key/values

 *

 * @access    public

 * @param    array

 * @return    string

 */

if ( ! function_exists('meta'))

{

    function meta($meta = array(), $newline = "\n")

    {

        $str = '';

        foreach ($meta as $key => $val)

        {

            $str .= '&lt;meta http-equiv="'.$key.'" content="'.$val.'" /&gt;'.$newline;

        }

        return $str;

    }

}

Why not come out in the documentation?

Thanks, and sorry my poor english

Developing models quickly? Any tips...

Posted by: El Forum - 10-21-2008, 04:32 AM - Replies (6)

	[eluser]Daniel H[/eluser] My new projects data model design comprises 66 db tables. Developing models for each table is terrifying me! The thing is every model is practically the same - class variables the same as the field names, and reset(), save(), delete() methods. Does anyone have a neat method for auto-generating their models or should I just get on with it and stop complaining?!

1 error message at the time, custom regexp check on field

Posted by: El Forum - 10-21-2008, 03:41 AM - Replies (4)

[eluser]CrustyDOD[/eluser]
Before i write my own 'addon' to the core, i'm just double checking that i haven't missed this somewhere in the guides and code..

1 error message at the time
Right now as far as i know (just started using CI) you have two options:
- Show ALL error messages at once
- Show error message per field (still shows more then just one error message)

I would like to show only one error message at the time by calling just one function. Is there a functions in the CI core right now that does this?

For example look at youtube sign up. If you miss one field, it shows just one error message for field you missed, and not ALL like CI is doing it right now.

custom regexp check on field
Is there a rule for custom regexp on a field?
Let's say i have drop down with values 1 and 2. I want to check that what someone submitted really is a value 1 or 2, and not 0, 3,4,5,... (faking form in this case).

Does this rule exist in the CI core?

Like i said, i'm just double checking cause i'm new to CI and i really like it.. and don't want to write something that already exist Smile

Using objects without instantiating them by default

Posted by: El Forum - 10-21-2008, 02:47 AM - No Replies

[eluser]mddd[/eluser]
I am building some applications which use lists of items. I want to use a structure where the list itself is represented by an object, and each item is also an object. So I would make a new list with $list = new List; and that would have a property $list->items containing an array of objects, each created by $item = new Item;

My question is, what is the best way to do this in the CI framework. Making 'list' and 'item' models, they would always be loaded if I declare them in a contructor in my controller. So I would have an 'extra' list object and item object 'hanging around'.

What would be the cleanest way to do something like this?
