Now before you burn me at the stake hear me out!
I want some keywords of a product description field to link to other products (kinda like mediawiki links), however at some point I need to make these associations and link the keywords up, so I'll need to do a search on each curly-braced word I find in the description and produce a formatted version of the description to cut down on processing these keyword links every time the description is displayed.
For ease/consistency I am creating all product links with a custom helper, and all I need to do is pass the product row in and the helper products a link for me with any options I specify. The only this is, is that I need to now do this in beforeSave() so I can populate description_formatted.
At the minute, beforeSave() checks for the original description row, then calls a private method in the model which matches each keyword, queries the db for a matching row... that is as far as I've got.
Just like any other MVC, Cake makes big restrictions how to couple your classes. This is needed to keep script kiddies to shoot themselves in the foot. However, there is a niche workaround for cake if you really need to get along: http://book.cakephp.org/view/933/The-App-Class
How I would do this? With the helper I would replace all curly braces words into links and when the user hovers the linked word I would call an Ajax which will get the word description or the link or whatever you need to do. This way you request the description only when it's needed.
If you still insist to use the helper - it's just a class in PHP, so you can include it in your Model, create an object of the class and use it's functions.
The third option is to create your own class and use it both in Model and the Helper.

I have two dynamic url with simillar structure. For example, lets say, Product page and category page.
I have set both pages in
Route::get('/{product}', [UsersController:: class, 'productDetail']);
Route::get('/{category}', [UsersController:: class, 'categoryProducts']);
But when I click on url which suppose to go in category page, it redirect to product page only because of same structure. How I can differentiate both URLs for Laravel without altering their url structure?
I don't think this can be done without modifying the URL pattern at least a little bit.
If you do something like /50?type=category then in the show method you can use the query parameter to determine which table to look at. But you'll have to use the same show method and I don't recommend doing it this way.
I hope someone else will be able to shine some more light on the matter.
this is the best practice for your case to make yourapi Resful
Route::get('/product/{product-id}', [UsersController:: class, 'productDetail']);
Route::get('/product/categories, [UsersController:: class, 'categoryProducts']);
learn more about Restful api here https://restfulapi.net/resource-naming/
This should be done by calling index, update diff() function. You can try by using the below:
Route::get('/category/{slug}', 'site\categorycontroller#show')->name('category.show');
Route::get('/product/{slug}', 'site\productcontroller#show')->name('product.show');
this question might be a bit special. I am using this Joomla 2.5 extensions to give authors the abilty to add Attachments to articles: Joomla Attachments
The extension renders an input field called "description" in a backend form to insert an file description for the provided file. Unfortunately it´s not taking HTML tags which I need. By saving the form it seems a strip_tags() or preg_replace() or something similar cleans the input. I combed through the code of the attachments extension but couldn´t find a place where the input is cleaned or saved.
To hopefully stay in the Question + Answer rule of Stackoverflow:
Is there a class which extensions inherit from the Joomla Core to save form data to a DB-table ( which also could be responsible to clean and validate user input )?
thanks for any idea,
tony
You should see how the field is defined first:
1. Form definition
look into the
administrator/component/yourcomponent/models/forms/somename.xml
there you could find a form definition, if so it will also specify the field type: depending on the type there are several available filters; for example the default textarea will strip html, and you need to set
filter="raw"
in order to enable it. see http://docs.joomla.org/Standard_form_field_and_parameter_types for a list of fields, click and you can find the available format options.
2. model
If the model inherits from JModelAdmin or JModelForm or other JModel* it will automatically handle binding of the forms' data to the database, look for the Save function which should receive the form $data.
3. more
There are at least another dozen possibilities. If the above didn't help, try finding the form: possibly you could find it just by looking at the markup. Once you have the form, check the following fields:
option
task
view
This should help you find the php code that is invoked based on the form:
if view is set, maybe in ./views/someview/view.html.php you could find the saving logic.
if task is set, look for a function with the same name in ./controller.php
if task contains a ".", look for the controller in the ./controllers/ folder.
if option is not the name of your component, your component is sending the data to another component for saving, and most likely set a return-url
A bit of context: I need to cache the homepage of my CakePHP site - apart from one small part, which displays events local to the user based on their IP address.
You can obviously use the <cake:nocache> tag to dictate a part of the page that shouldn't be cached; but you can't surround a controller-set variable with these tags to make it dynamic. Once a page is cached, that's it for the controller action, as far as I know.
What you can usefully surround with the nocache tags are elements and helpers. As such, I've created an element inside these tags, which calls a helper function to access the model and get the appropriate data. To get at the model from the helper I'm using:
$this->Modelname =& ClassRegistry::init("Modelname");
This seems to me, however, to be a kind of iffy way of doing things, both in terms of CakePHP and general MVC principles. So my question is, is this an appropriate way of getting what I want to do done, or should it ring warning bells? Is there a much better way of achieving my objectives that I'm just missing here?
Rather than using a Helper, try to put your code in an element and use requestAction inside of the element.
see this link
http://bakery.cakephp.org/articles/gwoo/2007/04/12/creating-reusable-elements-with-requestaction
This would be a much better approach than trying to use a model in your helper.
Other than breaking all the carefully-laid principles of MVC?
In addition to putting this item into an element, why not fetch it with a trivial bit of ajax?
Put the call in its own controller action, such that the destination URL -> /controller/action (quite convenient!)
Pass the IP back to that action for use in the find call
Set the ajax update callback to target within the element with the results of the call accordingly
No need to muck around calling Models directly from Views, and no need to bog things down with requestAction. :)

I'm making a site using Codeigniter and my URL for a particular product page is like http://www.domain.com/products/display/$category_id/$product_id/$offset
$offset is used for limiting the number of pages shown per page when using the Codeigniter's Pagination library.
How I want to make it such that my URL is something more human friendly, like http://www.domain.com/$category_name/$product_name/$offset ie. http://www.domain.com/weapons/proton-canon/3
Can anyone point me the general approach? I just started learning codeigniter and is working on my first project
You can use what's generally known as a URL slug to achieve this.
Add a new field to your table, called "url_slug" or similar. Now you will need to create a slug for each product, and store it in this field.
CI has a function in the URL helper - url_title($string) which will take a string, and convert it for use in URL's.
For example My product name would become my_product_name.
Now, in your method, you can either - keep the product_id intact, use this as a parameter for your method to show specific products, and use the slug for human friendly links, or you can just use the url_slug to refer to products.
Your URL may look like:
www.domain.com/$category_name/$product_id/my_cool_product/$offset
or it could look like
www.domain.com/$category_name/my_cool_product/$offset
with no ID. the choice is yours, but the url_slug may change - the ID won't. Which may have SEO impacts.
Regardless, your method needs to look something like:
function display_product($product_id, $url_slug, $offset) {
// do what you gotta do...
}
You can then use URL's like the above.
You will need to use URI routing as well, as the example above will attempt to look for a controller called $category_name and a method called my_cool_product, which will of course not exist.
See URI Routing for further info.
I'm using a web application project.
I have a folder in my web root called Users and in the folder I have a page called UserList.aspx
What I want to be able to do is type in Response.Redirect(Users.UserList.URL)
What I reckon I can probably do is create a class that extends Page and add a static property called URL that calls MethodInfo.GetCurrentMethod().ReflectedType (I think this works haven't tested) and then have that convert Users.UserList -> ~/Users/UserList.aspx
The problems with this method that I know of are one I need to go through every page and make it extend the base class and it doesn't work with any pages that contain a '-' character.
The advantages are that if pages are moved around then there aren't any broken links (Resharper gives out when there is a Page with the wrong namespace).
Also then every individual page that takes query string params could have a static method so that if I want to add/remove params I can see what uses those params etc.
Also if I want to call that page I don't have to check the name of the params e.g. UserId userId, Id or id. So that would look something like Users.ViewUser.GetUrl(1) -> ~/Users/ViewUser.aspx?UserId=1
So the question is: Is there a better way of doing this? Or is this a bad idea in principal?
You could just create an extension method for the base Page class that does what you are thinking. That would avoid having to go back and modify the base class for all your pages.
There is a better way. Create a traffic cop that knows about paths. Then if paths change, your data model changes or other stuff you just change that one place. Plus you could have read from a config file and make changes at run time.
Thus your call looks like this:
Repose.Redirect(TrafficCop["Users.UserList"].URL)
or some other way if you don't like the syntax.
The MethodInfo.GetCurrentMethod().ReflectedType doesn't work so I came up with another method of doing this using generics.
Instead of Users.ViewUser.GetUrl() or Users.ViewUser.URL it's GetUrl()
For a page with parameters it's still Users.ViewUser.GetUrl(1), it isn't ideal because they should both have the same way of being called but better than strings I guess.
Going to leave the question open for a while just in case.
edidt: I think I will actually just create another method called GetUrl(String getQuery) because if I have two parameters that are of the same type it doesn't work very well.
further edit: I found out how to do exactly what I want to do.
created a class called BasePage:Page where T : Page
on that are the static methods redirect and geturl
each page inherits from the base page as follows: MyPage:BasePage
Any page can redirect to that page by using the command MyPage.Redirect();
