I started writing some boring introduction but I’ll just skip to the point.
Zend Framework’s built in URL view helper Zend_View_Helper_Url
is discarding the query string of the URL, thus breaking some links.
Example: If I’m on a page like:
http://project/foo/bar/?param1=value1
and in the bar.phtml I use the Url helper like this:
<?php
<?= $this->url(array('param2' => 'value2')); ?>
I expect this:
http://project/foo/bar/param2/value2/?param1=value1
or something similar to this. This would be just perfect:
http://project/foo/bar/param1/value1/param2/value2
But no, it gives:
http://project/foo/bar/param2/value2/
After working on several workarounds, currently this is the best one I can think of take the link that is created by the built-in Url helper and add the query string on that link:
<?php
// Usage:
// <?= $this->myUrl($this->url(array('param2' => 'value2'))); ?>
// Output:
// http://project/controller/action/param2/value2/?param1=value1
class Zend_View_Helper_MyUrl
{
public function myUrl(&$url, &$toAdd = array())
{
$requestUri = Zend_Controller_Front::getInstance()->getRequest()->getRequestUri();
$query = parse_url($requestUri, PHP_URL_QUERY);
if($query == '')
{
return $url;
}
else if(empty($toAdd))
{
return $url . '/?' . $query;
}
else
{
$toAdd = (array)$toAdd;
$query = explode("&", $query);
$add = '/?';
foreach($toAdd as $addPart)
{
foreach($query as $queryPart)
{
if(strpos($queryPart, $addPart) !== False)
{
$add .= '&' . $queryPart;
}
}
}
return $url . $add;
}
}
}
The second parameter, $toAdd
, should be an array of parameters that we want to add to the URL. Say, if I have a query string like:
?param1=value1&someotherparam=anditsvalue
but want only to add the param1=value1
to the URL, I would pass param1 as the second parameter. Not passing anything as the second parameter will result in adding the complete query string to the URL.
This is an ugly hack to make ugly links work, but it works. Thoughts?
Cheers!
