I'm trying to write a route for an level N category depth. So an usual category URL would look like this:
http://website/my-category/my-subcategory/my-subcategory-level3/my-subcategory-level4
It has an unknown depth and my route has to match all possible levels. I made a route for this, but I can't get all the params from my controller.
$routeCategory = new Zend_Controller_Router_Route_Regex(
'(([a-z0-9-]+)/?){1,}',
array(
'module' => 'default',
'controller' => 'index',
'action' => 'index'
),
array( 1 => 'path'),
'%s'
);
$router->addRoute('category', $routeCategory);
I can't seem to find a way to send the route matched params to the controller. If you have a better solution, I'm open to suggestions!
I found a solution that I think fits my needs. I'll post it here for people who will end up in the same thing I got into.
Problem:
category/subcategory/subsubcategory/...category/subcategory/../page.htmladmin for example)Solution:
Zend_Controller_Router_Route_Regex as a starting point so I can benefit from the assemble() method)Actual code:
<?php
class App_Controller_Router_Route_Category extends Zend_Controller_Router_Route_Regex
{
public function match($path, $partial = false)
{
if (!$partial) {
$path = trim(urldecode($path), '/');
}
$values = explode('/', $path);
$res = (count($values) > 0) ? 1 : 0;
if ($res === 0) {
return false;
}
/**
* Check if first param is an actual module
* If it's a module, let the default routing take place
*/
$modules = array();
$frontController = Zend_Controller_Front::getInstance();
foreach ($frontController->getControllerDirectory() as $module => $path) {
array_push($modules, $module);
}
if(in_array($values[0], $modules)) {
return false;
}
if ($partial) {
$this->setMatchedPath($values[0]);
}
$myValues = array();
$myValues['cmsCategory'] = array();
// array_filter_key()? Why isn't this in a standard PHP function set yet? :)
foreach ($values as $i => $value) {
if (!is_int($i)) {
unset($values[$i]);
} else {
if(preg_match('/.html/', $value)) {
$myValues['cmsObject'] = $value;
} else {
array_push($myValues['cmsCategory'], $value);
}
}
}
$values = $myValues;
$this->_values = $values;
$values = $this->_getMappedValues($values);
$defaults = $this->_getMappedValues($this->_defaults, false, true);
$return = $values + $defaults;
return $return;
}
public function assemble($data = array(), $reset = false, $encode = false, $partial = false)
{
if ($this->_reverse === null) {
require_once 'Zend/Controller/Router/Exception.php';
throw new Zend_Controller_Router_Exception('Cannot assemble. Reversed route is not specified.');
}
$defaultValuesMapped = $this->_getMappedValues($this->_defaults, true, false);
$matchedValuesMapped = $this->_getMappedValues($this->_values, true, false);
$dataValuesMapped = $this->_getMappedValues($data, true, false);
// handle resets, if so requested (By null value) to do so
if (($resetKeys = array_search(null, $dataValuesMapped, true)) !== false) {
foreach ((array) $resetKeys as $resetKey) {
if (isset($matchedValuesMapped[$resetKey])) {
unset($matchedValuesMapped[$resetKey]);
unset($dataValuesMapped[$resetKey]);
}
}
}
// merge all the data together, first defaults, then values matched, then supplied
$mergedData = $defaultValuesMapped;
$mergedData = $this->_arrayMergeNumericKeys($mergedData, $matchedValuesMapped);
$mergedData = $this->_arrayMergeNumericKeys($mergedData, $dataValuesMapped);
/**
* Default Zend_Controller_Router_Route_Regex foreach insufficient
* I need to urlencode values if I bump into an array
*/
if ($encode) {
foreach ($mergedData as $key => &$value) {
if(is_array($value)) {
foreach($value as $myKey => &$myValue) {
$myValue = urlencode($myValue);
}
} else {
$value = urlencode($value);
}
}
}
ksort($mergedData);
$reverse = array();
for($i = 0; $i < count($mergedData['cmsCategory']); $i++) {
array_push($reverse, "%s");
}
if(!empty($mergedData['cmsObject'])) {
array_push($reverse, "%s");
$mergedData['cmsCategory'][] = $mergedData['cmsObject'];
}
$reverse = implode("/", $reverse);
$return = @vsprintf($reverse, $mergedData['cmsCategory']);
if ($return === false) {
require_once 'Zend/Controller/Router/Exception.php';
throw new Zend_Controller_Router_Exception('Cannot assemble. Too few arguments?');
}
return $return;
}
}
Usage:
Route:
$routeCategory = new App_Controller_Router_Route_Category(
'',
array(
'module' => 'default',
'controller' => 'index',
'action' => 'index'
),
array(),
'%s'
);
$router->addRoute('category', $routeCategory);
URL Helper:
echo "<br>Url: " . $this->_helper->url->url(array(
'module' => 'default',
'controller' => 'index',
'action' => 'index',
'cmsCategory' => array(
'first-category',
'subcategory',
'subsubcategory')
), 'category');
Sample output in controller with getAllParams()
["cmsCategory"]=>
array(3) {
[0]=>
string(15) "first-category"
[1]=>
string(16) "subcategory"
[2]=>
string(17) "subsubcategory"
}
["cmsObject"]=>
string(15) "my-page.html"
["module"]=>
string(7) "default"
["controller"]=>
string(5) "index"
["action"]=>
string(5) "index"
cmsObject is set only when the URL contains something like category/subcategory/subsubcategory/my-page.html
