Build a PHP theme#
Please see Build a Plugin for more details.
Single theme for WordPress or the whole
themes directory is defined as a PHP class library project (below) which is then referenced by the application. Application can have references to one or more themes.
Theme source files#
Sources of the theme complies with the regular WordPress codex. See Theme Handbook for more details.
Put the theme source files in an empty folder. Name or location of the folder are both not relevant.
Theme project file#
In order to compile the theme, create a project file in the theme folder.
┬ MyWordPressTheme └┬ MyWordPressTheme.msbuildproj <--- ├ readme.txt └ ...
By default, the name of the project file represents the theme's id. Id, or slug id is the identifier of the theme within WordPress. Also it denotates the folder name in which the theme files will be placed within
Project file is an XML file with the following content:
<Project Sdk="PeachPied.WordPress.Build.Plugin/5.9.0-preview14"> <PropertyGroup> <WpContentTarget>themes</WpContentTarget> </PropertyGroup> </Project>
Note the project file specifies a version after the slash, i.e.
"/5.9.3-rc-002". This corresponds to the version of PeachPied.WordPress.* packages which should be identical across all your application.
Build the theme#
In order to build the theme, run
dotnet build command:
The process will build the theme project. Eventual warnings will be outputed. Any error in the code will cause the build to fail.
If the process is run for the first time, it will first download the project Sdk and dependency packages (it means it requires an Internet connection).
Add theme to the application#
Assuming you have ASP.NET Core Application (called app) with WordPress (see quick start). Adding themes to the application is equivalent to adding project references or package references.
Either add project reference to the theme in Visual Studio IDE, or on command line, or edit the application's project file:
<ItemGroup> <ProjectReference Include="../MyWordPressTheme/MyWordPressTheme.msbuildproj" /> </ItemGroup>
Note, the theme is referenced by the application and it still needs to be activated in WordPress dashboard.
Package the theme#
Theme can be packed into a standard NuGet package. Run
dotnet pack command to create NuGet package:
Package (.nupkg) can be pushed into a NuGet feed. It is recommended to push packages to private feeds, or at least pack packages with a unique prefixed package identifier (i.e. MyName.MyWpThemes.MyWordPressTheme).
Add package reference to the application#
Once the theme is packed and available on a NuGet feed, it can be referenced as a package reference. Either add package reference to the theme in Visual Studio IDE, or on command line, or edit the application's project file:
<ItemGroup> <PackageReference Include="MyWordPressTheme" Version="1.0.0" /> </ItemGroup>
