Cakephp URL Slugs Question

my urls are like

example.com/deals/by_city/glasgow

I have an action "by_city" in a cities_controller that needs to grab the "glasgow" part of url and do stuff how can i do this with cakephp? I only want to know how to grab this part of the url and store it in variable.

All help appreciated :)

Thanks Dave

Cities Controller

function city_changer($CitySlug = null) {
        $active = $this->City->find('first', array('conditions' => array('City.slug' => $CitySlug)));
        $cities = $this->City->find('all', array('order' => array('City.name', 'City.name ASC')));

        $this->set(compact('active', 'cities'));
    }

City changer.ctp

<h2>Daily Deals from <?php echo $active['City']['name'];?></h2>
<form>
    <select name="file" size="1" onchange="loadPage(this.form.elements[0])" target="_parent._top" onmouseclick="this.focus()">

<?php foreach($cities as $city) {?>        
        <option value="/new_avc/deals/by_city/<?ph开发者_运维知识库p echo $city['City']['slug'];?>"><?php echo $city['City']['name'];?></option>
<?php }?> 

    </select>
</form>

default.ctp

<div id="header_wrapper">
    <div id="navigation">
        <div id="logo">
            <h1>Amazing Voucher Codes</h1>
        </div>
        <div id="city_nav">
            <?php echo $this->requestAction('/cities/city_changer/'.$city['City']['slug'], array('return'));?>
        </div>

As there is no database linked to default.ctp having problem getting the slug to pass to the controller :)

Assuming no custom router rules intervene, the third parameter in the URL (after controller/action) is the first parameter passed to the action.

class CitiesController extends AppController {
    function by_city( $cityName ) {
        // $cityName == 'glascow'
    }
}

You should just be able to add a $cityname parameter to the by_city method in the deals controller: this will automatically receive the city name (glasgow from the url above).
