How to Rewrite hardcoded url in yii?
I have made a url as follows,
CHtml::link($visit->health_institute_name, array('hospitals_single', 'id'=>$visit->health_institute_id));
It redireceted to the url as follow,
http://abc.com/hospital?name=yyy&id=14#ad-image-0
I Just want the url to be as follows,
http://abc.com/yyy
ie: i need to remove hospital?name= and &id=14#ad-image-0 from the url...
Can any one help?
In your urlManager rules, add this after all other rules:
'<name>' => 'hospital/view',
assuming view is the action you want to call - replace it with your action name
Then your link as follows:
CHtml::link($visit->health_institute_name, Yii::app()->getBaseUrl(true).'/'.$visit->name);
if you want to make a user friendly and seo-friendly like http://abc.com/hospital/yyy
You can use this:
class CarUrlRule extends CBaseUrlRule
{
public $connectionID = 'db';
public function createUrl($manager,$route,$params,$ampersand)
{
if ($route==='car/index')
{
if (isset($params['manufacturer'], $params['model']))
return $params['manufacturer'] . '/' . $params['model'];
else if (isset($params['manufacturer']))
return $params['manufacturer'];
}
return false; // this rule does not apply
}
public function parseUrl($manager,$request,$pathInfo,$rawPathInfo)
{
if (preg_match('%^(\w+)(/(\w+))?$%', $pathInfo, $matches))
{
// check $matches[1] and $matches[3] to see
// if they match a manufacturer and a model in the database
// If so, set $_GET['manufacturer'] and/or $_GET['model']
// and return 'car/index'
}
return false; // this rule does not apply
}
}

So I have the following action which I am trying to add output caching to:
[OutputCache(CacheProfile = OutputCacheProfileNames.Hours24)]
public ActionResult ContactUs()
{
ContactUsModel model = _modelBuilder.BuildContactUsModel();
if (Request.IsAjaxRequest())
{
return Json(StringFromPartial(partialTemplate, model), JsonRequestBehavior.AllowGet);
}
else
{
return View(model);
}
}
But this seem to cache the first view that is requested - ie either the json OR the normal view.
Is there a way to get the output caching to work for both views, without having to split them out of the same action?
You beat me to the punch in answering your own question, but I thought this code may still be helpful. Since varying by user is such a common scenario, you should probably account for being able to do that and your AJAX vary. This code will allow you vary on any number of custom parameters, by appending to a single string to vary on.
public override string GetVaryByCustomString(System.Web.HttpContext context, string custom)
{
var args = custom.ToLower().Split(';');
var sb = new StringBuilder();
foreach (var arg in args)
{
switch (arg)
{
case "user":
sb.Append(User.Identity.Name);
break;
case "ajax":
if (context.Request.Headers["X-Requested-With"] != null)
{
// "XMLHttpRequest" will be appended if it's an AJAX request
sb.Append(context.Request.Headers["X-Requested-With"]);
}
break;
default:
continue;
}
}
return sb.ToString();
}
Then, you would just do something like the following if you need to vary by multiple custom params.
[OutputCache(CacheProfile = OutputCacheProfileNames.Hours24, VaryByCustom = "User;Ajax")]
Then, if you ever need additional custom vary params, you just keep adding case statements to cover those scenarios.
Thanks to the comments by REDEVI_ for pointing me in the right direction, I have been able to solve this.
I changed my output caching to:
[OutputCache(CacheProfile = OutputCacheProfileNames.Hours24, VaryByCustom = "IsAjax")]
And then in my global.asax file, I added the following override:
public override string GetVaryByCustomString(HttpContext context, string custom)
{
if (context != null)
{
switch (custom)
{
case "IsAjax":
return new HttpRequestWrapper(context.Request).IsAjaxRequest() ? "IsAjax" : "IsNotAjax";
}
}
return base.GetVaryByCustomString(context, custom);
}
I have the following url mapping:
"/Some-Name".toLowerCase() {
controller ="user"
action = "show"
id = "f274b72e1309467e70"
}
Note this is not a duplicate of this: How to make my URL mapping case insensitive? It is a different case.
How can I make this URL mapping case insensitive?
Maybe you can try to use custom validator in constraint section. Please note that code below is not tested.
"/$path" {
controller ="user"
action = "show"
id = "f274b72e1309467e70"
constraints {
path((validator: { return it.equalsIgnoreCase("Some-Name") })
}
}
In my website I have the following route defined:
routes.MapRoute(
name: "Specific Product",
url: "product/{id}",
defaults: new { controller = "", action = "Index", id = UrlParameter.Optional }
);
In that way I want customers to be able to add the ID of the product and go to the product page.
SEO advisors have said that it would be better if we could add a description of the product on the URL, like product-name or something. So the URL should look something like:
/product/my-cool-product-name/123
or
/product/my-cool-product-name-123
Of course the description is stored in the db and I cannot do that with a url rewrite (or can I?)
Should I add a redirection on my controller (this would seem to do the job, but it just doesn't feel right)
On a few sites I checked they do respond with a 301 Moved Permanently. Is that really the best approach?
UPDATE
As per Stephen Muecke's comment I checked on what is happening on SO.
The suggested url was my own Manipulate the url using routing and i opened the console to see any redirections. Here is a screenshot:
So, first of all very special thanks to #StephenMuecke for giving the hint for slugs and also the url he suggested.
I would like to post my approach which is a mix of that url and several other articles.
My goal was to be able to have the user enter a url like:
/product/123
and when the page loads to show in the address bar something like:
/product/my-awsome-product-name-123
I checked several web sites that have this behaviour and it seems that a 301 Moved Permanently response is used in all i checked. Even SO as shown in my question uses 301 to add the title of the question. I thought that there would be a different approach that would not need the second round trip....
So the total solution i used in this case was:
I created a SlugRouteHandler class which looks like:
public class SlugRouteHandler : MvcRouteHandler
{
protected override IHttpHandler GetHttpHandler(RequestContext requestContext)
{
var url = requestContext.HttpContext.Request.Path.TrimStart('/');
if (!string.IsNullOrEmpty(url))
{
var slug = (string)requestContext.RouteData.Values["slug"];
int id;
//i care to transform only the urls that have a plain product id. If anything else is in the url i do not mind, it looks ok....
if (Int32.TryParse(slug, out id))
{
//get the product from the db to get the description
var product = dc.Products.Where(x => x.ID == id).FirstOrDefault();
//if the product exists then proceed with the transformation.
//if it does not exist then we could addd proper handling for 404 response here.
if (product != null)
{
//get the description of the product
//SEOFriendly is an extension i have to remove special characters, replace spaces with dashes, turn capital case to lower and a whole bunch of transformations the SEO audit has requested
var description = String.Concat(product.name, "-", id).SEOFriendly();
//transform the url
var newUrl = String.Concat("/product/",description);
return new RedirectHandler(newUrl);
}
}
}
return base.GetHttpHandler(requestContext);
}
}
From the above i need to also create a RedirectHandler class to handle the redirections. This is actually a direct copy from here
public class RedirectHandler : IHttpHandler
{
private string newUrl;
public RedirectHandler(string newUrl)
{
this.newUrl = newUrl;
}
public bool IsReusable
{
get { return true; }
}
public void ProcessRequest(HttpContext httpContext)
{
httpContext.Response.Status = "301 Moved Permanently";
httpContext.Response.StatusCode = 301;
httpContext.Response.AppendHeader("Location", newUrl);
return;
}
}
With this 2 classes i can transform product ids to SEO friendly urls.
In order to use these i need to modify my route to use the SlugRouteHandler class, which leads to :
Call SlugRouteHandler class from the route
routes.MapRoute(
name: "Specific Product",
url: "product/{slug}",
defaults: new { controller = "Product", action = "Index" }
).RouteHandler = new SlugRouteHandler();
Here comes the use of the link #StephenMuecke mentioned in his comment.
We need to find a way to map the new SEO friendly url to our actual controller. My controller accepts an integer id but the url will provide a string.
We need to create an Action filter to handle the new param passed before calling the controller
public class SlugToIdAttribute : ActionFilterAttribute
{
public override void OnActionExecuting(ActionExecutingContext filterContext)
{
var slug = filterContext.RouteData.Values["slug"] as string;
if (slug != null)
{
//my transformed url will always end in '-1234' so i split the param on '-' and get the last portion of it. That is my id.
//if an id is not supplied, meaning the param is not ending in a number i will just continue and let something else handle the error
int id;
Int32.TryParse(slug.Split('-').Last(), out id);
if (id != 0)
{
//the controller expects an id and here we will provide it
filterContext.ActionParameters["id"] = id;
}
}
base.OnActionExecuting(filterContext);
}
}
Now what happens is that the controller will be able to accept a non numeric id which ends in a number and provide its view without modifying the content of the controller. We will only need to add the filter attribute on the controller as shown in the next step.
I really do not care if the product name is actually the product name. You could try fetching the following urls:
\product\123
\product\product-name-123
\product\another-product-123
\product\john-doe-123
and you would still get the product with id 123, though the urls are different.
Next step is to let the controller know that it has to use a special filer
[SlugToId]
public ActionResult Index(int id)
{
}
i have mapping like this:
#URLMapping(id = "edituser", pattern = "/edituser/#{ id: userBean.userId}", viewId = "/faces/pages/users/editUser.xhtml")
and i want to redirect to it from an action method, so i tried the following:
return "pretty:edituser/" + userObj.getId();
but it didn't work, it reloads current page, please advise, thanks.
In your case something like this should work:
return "/faces/pages/users/editUser.xhtml?faces-redirect=true&id=" + userObj.getId();
Another option would be to obtain the UserBean, set the id property and then return pretty:editust. Something like this:
public class Whatever {
#Inject
private UserBean userBean;
public String action() {
// do something
userBean.setUserUd( someId );
return "pretty:edituser";
}
}
I want to give admin the option to change the URL identifier of MyCustomModule from backend.
E.g.: www.mydomain.com/identifier
What I did is the following:
In etc/system.xml
<identifier translate="label">
<label>SELF URL Identifier</label>
<frontend_type>text</frontend_type>
**<backend_model>press/config_identifier</backend_model>** // edited after answer
<sort_order>1</sort_order>
<show_in_default>1</show_in_default>
<show_in_website>1</show_in_website>
<show_in_store>1</show_in_store>
<comment>(eg: domain.com/identifier)</comment>
</identifier>
In helper/data.php
public function getUrl($identifier = null)
{
if (is_null($identifier)) {
$url = Mage::getUrl('').self::getListIdentifier();
} else {
//$url = Mage::getUrl(self::getListIdentifier()).$identifier;
**$url = Mage::getUrl(self::getListIdentifier(), array('identifier' => $identifier,'_use_rewrites'=>true)); //edited
}**
return $url;
}
after that i created a model file identifier.php :
class FME_Press_Model_Config_Identifier extends Mage_Core_Model_Config_Data
{
protected function _afterSave()
{
if ($this->isValueChanged()) {
$path = $this->getValue();
// for each $store and $id combination...
Mage::getModel('core/url_rewrite')
->loadByIdPath('press/'.$store.'/'.$identifier)
->setRequestPath($path.'/'.$identifier)
->save();
}
}
}
in config.xml i wrote this:
<events>
<controller_front_init_routers>
<observers>
<press>
<type>singleton</type>
<class>FME_Pres_Controller_Router</class>
<method>initControllerRouters</method>
</press>
</observers>
</controller_front_init_routers>
</events>
and also this is present in my file, m not sure whether it is relevant :
<adminhtml>
<args>
<modules>
<FME_Press_Override before="Mage_Adminhtml">FME_Press_Override_Admin</FME_Press_Override>
</modules>
</args>
</adminhtml>
NOTE: I had been told to make some changes in Controller/Router.php but I don't know what changes to make.
If you want I can add that code also?
Now, what else should I do?
I feel changing the application's router is entirely the wrong approach to take. It is messy and can be easily broken if another module overrode it for a similar purpose. The clean way is with URL rewrites.
You want it to be alterable so you cannot use a fixed XML based rewrite. Instead let's look at the built in rewrite system.
First in your module's etc/config.xml file set up a normal controller.
<frontend>
<routers>
<MyCustomModule>
<use>standard</use>
<args>
<module>Example_MyCustomModule</module>
<frontName>customlist</frontName>
</args>
</MyCustomModule>
</routers>
</frontend>
Here the front name used is customlist, that will always work and shouldn't conflict with any other front name, the rewritten name shall be in addition to this. Now whenever you generate an URL (perhaps in a helper function) you do so to this apparently fixed front name.
$url = Mage::getUrl('customlist', array(
'id' => $id, // 'id' will get used in the "target path" later
'_use_rewrites' => true
));
Note that the variable identifier ($id) is passed to the getUrl function rather than simply appending to it's result. If the function returns an URL with a query (&) or fragment (#) the identifier could have been appended to the wrong part.
The next step is to create rewrite records for every possible combination of identifier and store. You probably have a finite number of lists so this is possible, perhaps identifiers are particular to stores so only need to be defined once each. Either loop through all your lists in an installer script or have each list create rewrites when it is saved.
$path = Mage::getStoreConfig('custom/config/identifier', $storeId);
// Change 'custom/config/identifier' to match the path used in system.xml
$rewrite = Mage::getModel('core/url_rewrite')
->loadByIdPath('customlist/'.$store.'/'.$id);
if ($rewrite->getId()) {
// A rewrite already exists, you might want to skip creating another
continue;
}
Mage::getModel('core/url_rewrite')
->setStoreId($storeId)
->setIsSystem(true) // set to false to allow admin to edit directly
->setOptions('RP') // Redirect Permanent 301
->setIdPath('customlist/'$storeId.'/'.$id) // should never change
->setTargetPath('customlist/index/index/id/'.$id) // what gets used
->setRequestPath($path.'/'.$id) // the path used in the browser
->save();
So now if the admin sets the URL path to be "foo/bar" and requests the page "www.mydomain.com/foo/bar/3" it will be rewritten to "customlist/index/index/id/3" and the method Example_MyCustomModule_IndexController::indexAction() will be called. The file containing that will of course be app/code/local/Example/MyCustomModule/controllers/IndexController.php and the 3 value is retrieved there:
public function indexAction()
{
$id = $this->getRequest()->getParam('id'); // 'id' was specified in getUrl()
// use $id here...
}
It should work by now but what if a list is removed? The rewrites need to be updated for each store. Models have a _beforeDelete method, override it for your list objects.
protected function _beforeDelete()
{
Mage::getModel('core/url_rewrite')
->loadByIdPath('customlist/'.$storeId.'/'.$this->getId())
->delete();
return parent::_beforeDelete();
}
Similarly they need to be updated to match changes in configuration.
etc/system.xml
<identifier translate="label">
<label>SELF URL Identifier</label>
<frontend_type>text</frontend_type>
<backend_model>myCustomModule/config_identifier</backend_model>
...
</identifier>
Model/Config/Identifier.php
class Example_MyCustomModule_Model_Config_Identifier
extends Mage_Core_Model_Config_Data
{
protected function _afterSave()
{
if ($this->isValueChanged()) {
$path = $this->getValue();
// for each $store and $id combination...
Mage::getModel('core/url_rewrite')
->loadByIdPath('customlist/'.$store.'/'.$id)
->setRequestPath($path.'/'.$id)
->save();
}
}
}
