Do you own a membership website or forum? Then you must take steps to restrict file uploading permission in WordPress. In fact, all users whether converting HTML CSS to WordPress or acquiring new interfaces must exercise control over the feature. Any website which allows visitors to upload items must have a regulatory system in place. This will prevent people from uploading unnecessary or bulky elements which may harm the interface. Large size items can cause the page loading speed to drop down and have a bad impact on the user experience. In this tutorial, a simple method to restrict the uploading permissions is being provided for WordPress website owners. However, before discussing the process it will be pertinent to know about the file permissions system of the CMS.
Understanding WordPress File Permissions
In WordPress, there are three kinds of permissions that can be granted to three types of users. The first kind of user is called user or owner. It is generally the website owner who is specified in this category. The second type is the group which can be a set of people chosen to perform specific functions. The website owner is usually a part of the group. Finally, the last type of user set is called the world. It comprises of all the visitors to the website.
You can specify three kinds of permissions to all the users:
- Read: Only allowed to view or read a file. No alterations can be made to the file.
- Write: Permitted to modify a file.
iii. Execute: Allowed to execute i.e read, write, modify or delete the file.
Each permission has been assigned specific values which are as follows:
- Read: 4
- Write: 2
iii. Execute: 1
These values are used to compute the permission mode. For instance,
User: r+w+x = 4+2+1 = 7
Group: r = 4+0+0 = 4
World: r = 4+0+0 = 4
This means that the user has rwx (7) permission to read, write, and execute the file. The group and others are only allowed to read the file. Simply taking a look at the string, 744 will help you understand the permission mode.
Permissions vary from one hosting service to another. However, the user account on the website server must be the owner of all files. Files requiring to write access from WordPress must be owned by the user. In case they are owned by a group, the user must be a part of the group. All core files must be writable only by the user account.
