Laravel - Extending Model

由 淺唱寂寞╮ 提交于 2020-02-24 11:30:14
问题 I've created a BaseModel class, which extends from Model. It seemed like everything was working fine, but now I've run into a problem when saving. I'm overriding the save() method in this BaseModel. I'd just like to add some attributes to the model before saving. So I do that, then call return parent::save($options); . The method signature is still the same: public function save(array $options = []) . It appears to be grabbing the name of the BaseModel class for the table name when performing

do extended classes inherit static var values (PHP)?

由 坚强是说给别人听的谎言 提交于 2020-01-15 11:19:06
问题 If I have a base class that contains a static var, I then set this static var, and then have a class that extends the base class, will the extended class retain the value of the static var that I have already set in the base class? 回答1: Yes, although they're different variables, the static variables in both classes are in the same reference set. You can break this reference set though, by using reference assignment ( =& ) or by redeclaring it in the extended class: class base { public static

问题 The title explains it pretty well. I'm trying to add a new shipping method (cost-based shipping) by extending the class.

Custom Control in ASP.NET C#

问题 I created a simple custom control that only inherits from the Literal control, and doesn't have any extensions yet, code is empty. Namespace: CustomControls Class name: Literal : System.Web.UI.WebControls.Literal Next thing I do is registering this control in the aspx page as following: <%@ Register TagPrefix="web" Namespace="CustomControls" %> (I read in few tutorials that this is one of the ways to register it, besides web.config etc.) After all, no intellisence for me, and worse- I get a
