Laravel动态包含带值模板报错，如何正确实现动态引入？

Hey there! I get it—you’re trying to pull in a theme-specific header template dynamically, but that @include('{{ site('theme') }}.header') syntax is throwing errors. Let’s sort this out quickly.

Why Your Original Code Fails #

Blade’s @include directive expects a string representing the template path, not output syntax ({{ }}). Those double handlebars are meant to print values directly to the browser, not pass them as arguments to Blade directives. That’s why even though {{ site('theme') }} outputs test, wrapping it in quotes and handlebars inside @include doesn’t work—it’s treating the whole {{ site('theme') }}.header as a literal string instead of parsing the dynamic value.

The Correct Approaches #

1. Directly Use the Function in @include

You can pass the result of site('theme') directly, concatenate the .header suffix, and Blade will parse it correctly:

@include(site('theme') . '.header')

When site('theme') returns test, this resolves to @include('test.header'), which points to resources/views/test/header.blade.php—exactly what you want.

2. Store the Theme in a Variable (For Clarity)

If you need to reuse the theme value elsewhere in your template, it’s cleaner to store it first:

@php
    $activeTheme = site('theme');
@endphp

@include($activeTheme . '.header')

This way, you avoid repeating the site('theme') call and make your code a bit more readable.

Quick Check to Avoid Other Errors #

Make sure your template file actually exists at the path Blade is looking for! For a theme value of test, the file should be located at:
resources/views/test/header.blade.php
If the path or filename is wrong (case matters on some servers!), you’ll still get an include error even with the correct syntax.
