Depending on the information in your database, your object output will look similar to the following:. One of the many benefits of using an OOP approach with RBAC is that it allows you to separate code logic and validation from object specific tasks.
For example, you could add the following methods to your Role class to help manage role specific operations such as inserting new roles, deleting roles and so on:. Roles on the other hand can be easily created, modified or deleted via an administration interface. The more roles and permissions you have the more difficult things will be to manage; keeping the lists minimal is important, but sometimes the contrary is unavoidable.
I can only advise that you use your best judgement and try not to get carried away. You now have an understanding of role based access control and how to implement roles and permissions into an existing application. One of the easiest safety measures to put in place, yet one that makes a world of difference is to set PHP file permissions.
Overlooking PHP file permissions can lead to serious vulnerabilities that can lead to hack or a data breach! Read on to find out what they are and how you can set them.
As the name suggests, PHP file permissions are a guide for a file with respect to who can do what to it. Setting up file permissions not only ensures that unauthorized users are kept at bay, but that all loopholes where your site can be accessed are closed. This makes your website less vulnerable to predators who are waiting for an opportunity to steal your data.
Permissions follow octal numbering. That means, digits in PHP file permissions can take values from , where each digit has a significance or meaning. Here is a table of permission values:. These permissions are allotted to the owner, to groups, and to everyone else, from left to right. Here are some common permissions to set up and what they mean:. While developing a software or a website, the file permissions usually go unchanged from the default settings.
The fopen function not only opens an existing file, it can also create a new file for you with certain permissions, which are set by default if left unspecified. PHP also offers some other functions like checking and changing file permissions. Here are a few simple steps that can save you time, money, and resources by blocking out any malicious users who can take advantage of your unmodified file permissions:. Map existing file users to the level of access they require and provide them with permissions accordingly.
And there you have it. Simple and straight forward. No real frills, though. As it sits now the user is redirected to a page that just tells then simply that they need to be a logged in user. There are a hundred ways to modify this to make it more convenient on the user. Hopefully this gives you some ideas on what can be done to help legitimate users get to your content while keeping the rif-raff from poaching it.
While the approach may still be valid, it is likely there are key differences in newer versions of the software invovled that prevent the code below from working. These next two lines will already exist in your. This file not only delete file record from DB table but also delete file from directory as well.
