I want to make custom routing and I did it, I understand that using $route['blog'] = 'Main/blog'; for ie, we can forward this to corresponding controller and that is OK.
Now I want to make it more elegant / dynamic. So my idea is to try something like this:
$ci = & get_instance();
$ci->load->helper('language');
$route[$ci->lang->line('url_About_Me')] = 'Main/about/' . $ci->lang->line('ISO 639-1');
Because URL part of url_About_Me will be dynamically configured and can be any that users wants to be, and still controller function about will stay just as that (that is part of design).
Now this is throwing an error:
Message: Class 'CI_Controller' not found
So, does anyone know how to overcome this? And is there anywhere a diagram or some workflow where I can see what comes first and last in codeigniter from the moment URL is requested by user.
Thanks.

Background
I've inherited an e-commerce website using the usual aspnet's MVC5 / razor / jquery. The goal is gobalizating the website and add a language selector, to support the two main country/language targeting strategies. I've just accomplished the first step, wich is routing the website so it handles domain.com/en/, domain.com/es/, domain.com/es-mx/... Using http://jittuu.com/2014/3/17/AspNet-localization-routing After this, entering the domain with a non-existant locale redirects to the default one. There's a custom IRouteHandler that get's the httprequest, checks the locale and puts it if it needs to:
Public Class LocalizationRedirectRouteHandler
Implements IRouteHandler
Public Function GetHttpHandler(requestContext As RequestContext) As IHttpHandler Implements IRouteHandler.GetHttpHandler
Dim routeValues = requestContext.RouteData.Values
Dim cookieLocale = requestContext.HttpContext.Request.Cookies("locale")
If cookieLocale IsNot Nothing Then
routeValues("culture") = cookieLocale.Value
Return New RedirectHandler(New UrlHelper(requestContext).RouteUrl(routeValues))
End If
Dim uiCulture = CultureInfo.CurrentUICulture
routeValues("culture") = uiCulture.Name
Return New RedirectHandler(New UrlHelper(requestContext).RouteUrl(routeValues))
End Function
End Class
There are thousands of "inline" AJAX calls to routes across the website written without an #Html helper because the project has separate, bundled js files, failing. There are hundreds of routes failing because the project controllers are using attribute routing and it's not specifying locale. For example, a simple link to a product features is failing because the controller has a route specifying
/product/{id}
but the URL looks like
/es-MX/product/{id}
Question:
What's the right way to proceed here?
I was expecting those AJAX and links without locale to be redirected, but they are not.
Should I rewrite all those files so they specify current locale? Is there any other "healthy" way to do this, like extending BaseController and add culture as a route prefix?
Thank you in advance for your time, I'm terribly lost here.
Turns out, this answer by #NightOwl888 is the closest I've found to a solution to the problem I was facing. After including this changes to my project, I have almost everything working out and sporting a wonderful culture prefix on the URL. There's still a few things to work out though:
My default route sports no culture in the URL, wich may be against one of our goals. I can work on that toying (or removing) the defaultCulture constraint.
There are hundreds of windows.location on js files targeting routes without culture. I may be able to work on that via JS global variable storing the culture.
I still need to find a nice way to handle URL localization. Hopefully this project will help me through (also directed there by #NightOwl888).
I am using code Igniter for my PHP project. I want to give provision in my site such that users can create new pages of their own, and access them directly from domain.com/their_page_name.
But, my developers have raised a concern that, 1000's of dynamic links that are presented in the format of domain.com/ is "not good for site's performance". For some 10-15 pages, it is fine. But, beyond that, it would effect the site's performance.
So, they proposed that the URL format should be like www.domain.com/something/page_name (here, 'something' is the controller name, as they mentioned it)
But, I really can't sacrifice my framework nor my requirement.
Is there any way that I can achieve the format of "www.domain.com/page_name" without effecting the site's performance?
Thanks in advance.
No issues on
Www.domain.com\userpagename.
It's not a framework issues. Codeigniter support this type of URL.you can create n no of URL.
Performance will matter how you are handling that particular controller or that particular function.
If may be 10 may be 100 ,work around same way.
You just have to put route accordingly.
$route[default_controller]=userurl;
$route[userurl/(:any)]=userurl yourfunction/$1`;
What it seems you need is dynamic controller, which can be done using Codeigniter's build in function _remap().
A code example is:
public function _remap($method){
if($method != null){
$this->yourFunction($method);
} else {
// handle the error as you like
}
}
public function yourFunction($key){
// your code logic here
}
All this code block goes inside your controller.
Edit: the performance is exactlu the same as going with domain.com/controller/method. What it matters, as stated above, is how you handle the data.
i have create module using module builder , now i am having a field called as book Name
now if i give same book name 2 time t is accepting .
i don't want to use and plug in for checking duplicate value because i want to learn the customization through code .
so i can call ajax and check in data base weather the same book name is exist in db or not but i don't know how controller works in sugar crm . and how to call ajax in sugar crm .
can any one guide me , your help is much appreciated .
If you really want to accomplish this using ajax then I'd recommend an entryPoint as the way to go. This customization will require a couple of simple things. First you'll write a little bit of javascript to perform the actual ajax call. That ajax call will post to the entryPoint you write. The entryPoint will run the query for you and return a response to you in the edit view. So lets get started by writing the entryPoint first.
First, open the file custom/include/MVC/Controller/entry_point_registry.php. If the folder structure and file do not exist yet, go ahead and create them.
Add the following code to the entry_point_registry.php file:
$entry_point_registry['test'] = array('file' => 'custom/test.php', 'auth' => true);
Some quick explanation about that line:
The index value of test can be changed to whatever you like. Perhaps 'unique_book_value' makes more sense in your case. You'll see how this value is used in a minute.
The file value in the array points to where you're gonna put your actual code. You should also give this a more meaningful name. It does NOT need to match the array key mentioned above.
The 'auth' => true part determines whether or not the browser needs to have an active logged in session with SugarCRM or not. In this case (and almost all) I'd suggest keeping this to true.
Now lets look at the code that will go in custom/test.php (or in your case unique_book_name.php):
/* disclaimer: we are not gonna get all crazy with using PDO and parameterized queries at this point,
but be aware that there is potential for sql injection here. The auth => true will help
mitigate that somewhat, but you're never supposed to trust any input, blah blah blah. */
global $db; // load the global sugarcrm database object for your query
$book_name = urldecode($_REQUEST['book_name']); // we are gonna start with $_REQUEST to make this easier to test, but consider changing to $_POST when confirmed working as expected
$book_id = urldecode($_REQUEST['book_id']); // need to make sure this still works as expected when editing an existing record
// the $db->quote is an alias for mysql_real_escape_string() It still does not protect you completely from sql injection, but is better than not using it...
$sql = "SELECT id FROM book_module_table_name WHERE deleted = 0 AND name = '".$db->quote($book_name)."' AND id <> '".$db->quote($book_id)."'";
$res = $db->query($sql);
if ($db->getRowCount($res) > 0) {
echo 'exists';
}
else {
echo 'unique';
}
A note about using direct database queries: There are api methods you can use to accomplish this. (hint: $bean->retrieve_by_string_fields() - check out this article if you wanna go that route: http://developer.sugarcrm.com/2012/03/23/howto-using-the-bean-instead-of-sql-all-the-time/) However, I find the api to be rather slow and ajax should be as fast as possible. If a client asked me to provide this functionality there's a 99% chance I'd use a direct db query. Might use PDO and parameterized query if I'm feeling fancy that day, but it's your call.
Using the above code you should be able to navigate to https://crm.yourdomain.com/index.php?entryPoint=test and run the code we just wrote.
However at this point all you're gonna get is a white screen. If you modify the url to include the entryPoint part and it loads your home page or does NOT go to a white screen there are 3 potential causes:
You put something different for $entry_point_registry['test']. If so change the url to read index.php?entryPoint=whatever_you_put_as_the_array_key
You have sugar in a folder or something on your domain so instead of crm.yourdomain.com it is located somewhere ugly and stupid like yourdomain.com/sugarcrm/ if this is the case just make sure that your are modifying the url such that the actual domain portion is preserved. Okay I'll spell it out for you... https://yourdomain.com/sugarcrm/index.php?entryPoint=test
This is more rare, but for some reason that I cannot figure out apache sometimes needs to be reloaded when adding a new entrypoint. If you have shell access a quick /etc/init.d/apache2 reload should do the trick. If you don't have shell access you may need to open a ticket with your hosting provider (or get a fricking vps where you have some control!!!, c'mon man!)
Still not working? Did you notice the "s" in https? Try http instead and buy a fricking $9 ssl cert, geez man!
Okay moving on. Let's test out the entryPoint a bit. Add a record to the book module. Let's add the book "War of Art" (no, not Art of War, although you should give that a read too).
Now in the url add this: index.php?entryPoint=test&book_name=Art%20of%20War
Oh gawd that url encoding is hideous right! Don't worry about it.
You should hopefully get an ugly white screen with the text "exists". If you do let's make sure it also works the other way. Add a 2 to the book name in the url and hopefully it will now say "unique".
Quick note: if you're using Sugar you're probably also using mysql which is case insensitive when searching on strings. If you really need case sensitivity check out this SO article:
How can I make SQL case sensitive string comparison on MySQL?
Okay so now we have our entryPoint working and we can move on to the fun part of making everything all ajaxical. There are a couple ways to go about this, but rather than going the most basic route I'm gonna show you what I've found to be the most reliable route.
You probably will need to create the following file: custom/modules/CUSTOM_BOOK_MODULE/views/view.edit.php (I hope by now I don't need to point out changing that path to use your module name...
Assuming this file did not exist and we are starting from scratch here is what it will need to look like:
if(!defined('sugarEntry') || !sugarEntry) die('Not A Valid Entry Point');
class CUSTOM_BOOK_MODULEViewEdit extends ViewEdit
{
public function display()
{
// make sure it works in the subpanel too
$this->useForSubpanel = true;
// make the name value available in the tpl file
$this->ss->assign('name_value', $this->bean->name);
// load the parsed contents of the tpl into this var
$name_input_code = $this->ss->fetch('custom/modules/CUSTOM_BOOK_MODULE/tpls/unique_book_checker.tpl.js');
// pass the parsed contents down into the editviewdefs
$this->ss->assign('custom_name_code', $name_input_code);
// definitely need to call the parent method
parent::display();
}
}
Things are looking good. Now we gotta write the code in this file: custom/modules/CUSTOM_BOOK_MODULE/tpls/unique_book_checker.tpl.js
First a couple of assumptions:
We're going to expect that this is Sugar 6.5+ and jquery is already available. If you're on an earlier version you'll need to manually include jquery.
We're going to put the event listener on the name field. If the book name value that you want to check is actually a different field name then simply adjust that in the javascript below.
Here is the code for custom/modules/CUSTOM_BOOK_MODULE/unique_book_checker.tpl.js:
<input type="text" name="name" id="name" maxlength="255" value="{$name_value}" />
<span id="book_unique_result"></span>
{literal}
<script type="text/javascript">
$(document).ready(function() {
$('#name').blur(function(){
$('#book_unique_result').html('<strong> checking name...</strong>');
$.post('index.php?entryPoint=test', {book_name: $('#name').val(), book_id: $('[name="record"]').val()}, function(data){
if (data == 'exists') {
removeFromValidate('EditView', 'name');
addToValidate('EditView', 'name', 'float', true, 'Book Name Must be Unique.');
$('#book_unique_result').html('<strong style="color:red;"> ✗</strong>');
}
else if (data == 'unique') {
removeFromValidate('EditView', 'name');
addToValidate('EditView', 'name', '', true, 'Name Required');
$('#book_unique_result').html('<strong style="color:green;"> ✓</strong>');
}
else {
// uh oh! maybe you have php display errors on?
}
});
});
});
</script>
{/literal}
Another Note: When the code detects that the name already exists we get a little hacky and use Sugar's built in validation stuff to prevent the record from saving. Basically, we are saying that if the name already exists then the name value MUST be a float. I figured this is pretty unlikely and will do the trick. However if you have a book named 3.14 or something like that and you try to create a duplicate this code will NOT prevent the save. It will tell you that a duplicate was found, but it will not prevent the save.
Phew! Okay last two steps and they are easy.
First, open the file: custom/modules/CUSTOM_BOOK_MODULE/metadata/editviewdefs.php.
Next, find the section that provides the metadata for the name field and add this customCode attribute so that it looks like this:
array (
'name' => 'name',
'customCode' => '{$custom_name_code}',
),
Finally, you'll need to do a quick repair and rebuild for the metadata changes to take effect. Go to Admin > Repair > Quick Repair & Rebuild.
Boom! You should be good to go!
I want to create location pages in my codeigniter site. So I have one contrller named locations and index method. So all the requests http://mysite.com/location_name should be landed to http://mysite.com/index.php/locations/index. And all other should work as it is like http://mysite.com/login should be landed to http://mysite.com/index.php/home/login. Contact us http://mysite.com/contact-us should be landed to http://mysite.com/index.php/home/contact.
I tried to achieve this by writing following line route rule (route.php):
$route['(:any)'] = 'locations'; //location name can be anything around the world
So locations are working fine, but http://mysite.com/login and http://mysite.com/contact-us are not working, they redirecting continuously in infinite loop.
Please suggest the solution. Thank.
The routes are applied from top to bottom, so you need to have your more specific rules listed first, then your more generic rules last:
$route['login'] = 'home/login';
$route['contact-us'] = 'home/contact';
$route['(:any)'] = 'location/index';
I see that you mentioned you've tried changing the order of rules in your route file. So If you have done this and it's not working - you have something else going on.
I would check these things:
.htaccess file (if you're using it)
controllers that are causing the infinite loop (any redirections in there, _remap method, etc. )
Is there a way (via routing) in CodeIgniter to change:
example.com/category/4 to example.com/category/foo-bar
where Foo Bar is the name of category 4 in the database?
Access from the SEO-friendly URL should be allowed, but access via the integer should cause a 404 error.
This should also work dynamically, where any integer is automatically converted to a URL-safe version of its corresponding category name.
I've seen a few solutions that use 'slugs'... is there a decent alternative?
Thanks.
I've only been working with CodeIgniter for the past couple of months in my spare time, so I'm still learning, but I'll take a shot at this (be gentle):
There is a url_title() function in the URL Helper (which will need loaded, of course) that will change Foo Bar to foo-bar.
$name = 'Foo Bar';
$seo_name = url_title($name, TRUE);
// Produces: foo-bar
http://codeigniter.com/user_guide/helpers/url_helper.html
The URL helper strips illegal characters and throws in the hyphens by default (underscores, by parameter) and the TRUE parameter will lowercase everything.
To solve your problem, I suppose you could either do a foreach statement in your routes.php file or pass the url_title() value to the URL, rather than the ID, and modify your code to match the url_title() value with its category name in the DB.
Afaik the link between 4 and "foo-bar" has to be stored in the DB, so you'll have to run some queries. This is usually not done via routing in CI. Also routing just points a URL to a controller and function and has little to do with url rewriting.
Why don't you want to use slugs?
You could try storing the search engine friendly route in the database using this method or this one.
I wouldn't recommend throwing a 404. Use the canonical link tag in the instead if your worried about Google indexing both http://googlewebmastercentral.blogspot.com/2009/02/specify-your-canonical.html.
But if you really want to I guess you could write a function that is called during the pre_controller hook http://codeigniter.com/user_guide/general/hooks.html that checks to see if the URL has an integer as the second segment then call the show_404() method. Perhaps a better solution when writing this function would be to redirect to the SEO friendly version.
Is there a way (via routing) in CodeIgniter to change:
example.com/category/4 to example.com/category/foo-bar
where Foo Bar is the name of category 4 in the database?
Yes.
Using CI 3,
http://www.codeigniter.com/user_guide/general/routing.html
Use Callbacks, PHP >= 5.3
$route['products/([a-zA-Z]+)/edit/(\d+)'] = function ($product_type, $id)
{
return 'catalog/product_edit/' . strtolower($product_type) . '/' . $id;
};
You can route to call a function to extract the name of the category.
Hope I answered your question and can help more people to like codeigniter as I believe it's speedy and light.
Slugs usage is important to make web application more secure which i think is important.
A better recommendation will be to use route to give you a better solution.
$route['(:any)/method/(:num)'] = 'Class/method';
or
$route['(:any)/method/(:num)'] = 'Class/method/$1';
$route['(:any)/gallery/(:num)'] = 'Class/gallery/$1';
