CakePHP Routing With Parameters

Anything you need to know with cakePHP routing can be found here.

Here is an example to illustrate routing with parameters.

/config/routes.php

Router::connect(
    '/:controller/:year/:month/:day',
    array('action' => 'index', 'day' => null),
    array(
        'year' => '[12][0-9]{3}',
        'month' => '(0[1-9]|1[012])',
        'day' => '(0[1-9]|[12][0-9]|3[01])'
    )
);

Parameters can be access like this:

/controllers/controller.php

function index(){
    // params is stored in $this->params
    $year = $this->params['year'];
    $month = $this->params['month'];
    $day = $this->params['day'];
    
    //
}

Increase Performance of Loop with Large Arrays

In PHP, this is how we usually loop through arrays:

<?php
for ($i=0; $i<count($big_array); $i++){
 //
}
?>

Having this approach, program will try to count the $big_array every time it loops and it may cause some performance issues. To make it more efficient, we should code it this way:

<?php
for ($i=0, $n=count($big_array); $i<$n; $i++){
 //
}
?>

It does the counting during initialization only.

How to Route Admin Actions in CakePHP 1.2

This is how to setup the routing:

Router::connect('/admin/:controller/:action/*', array('admin'=>'true','prefix'=>'admin', 'controller'=>'controller', 'action'=>'action'));

Indenting Tree List in Form Input Select using ' ' as spacer

This is the scenario in cakePHP 1.2.

In your controller, you have an action:

function add() {
 ... 
 $categories = $this->Listing->Category->generatetreelist(null, null, null, ' ');
 $this->set(compact('categories','keywords','metros','states'));
}

where ' ' is your spacer.

Your view will have something like this:

...
echo $form->input('Category');
...

The above combination will display a drop down menu with the '&nsbp;' printed as '&nbsp' and not as a space. So how would you do it in cakePHP 1.2?

The key here is in the view file.

instead of the above statement, you should have this:

...
echo $form->input('Category', array('escape' => false));
...

Hope this one helps.
