Laravel：从 package 扩展子视图中的布局

Question

We have been converting our MVC contents into separate packages from our Laravel app. We still keep our layouts in the actual application, but the problem is that the packages are not able to use the @extends('layouts.mainlayout') directive approach to templating where we can render the sections inside the layout like such: <title>App Name - @yield('title')</title> using the section directives.

Here is a snapshot of the design of the app:

Laravel Application

Main layout aka "master" page of the entire application

 resources/views/layouts/mainlayout.blade.php

Example of a view from the application using mainlayout.blade.php

ex: resources/views/home/index.blade.php

 @extends('layouts.mainlayout')
 @section('title')
     Home 
 @stop

 @section('css') 
    @parent
   <style>
     .#alp{font-size: 12pt;}
   </style>
 @stop

@section('content')
<table id="alp" class="display" style="width:100%">
    <thead>
        <tr>
            <th>Name</th>
            <th>Position</th>
            <th>Office</th>
            <th>Age</th>
            <th>Start date</th>
            <th>Salary</th>
        </tr>
    </thead>
    <tbody>
    </tbody>
</table>
@stop

@section('custom_js')
<script>
$(document).ready(function() {
    var t = $('#alp').DataTable( {
                "responsive": true,
        "scrollX": true,
        "initComplete": function(){
            CTSA.showRecordCount(t);
            CTSA.Flags.initCompleteDt = true;
        },
        "fnDrawCallback":function(){
            if(CTSA.Flags.initCompleteDt)
                CTSA.showRecordCount(t);
        }       
    });
} );
</script>
@stop

NOT WORKING PROPERLY

Example from package using mainlayout.blade.php

ex: packages/testpackage/resources/views/test.blade.php

@extends('layouts.mainlayout.php')

 @section('title')
     Test Page 
 @stop

I can get the package to use the layout, but I cannot get it to use it the way it should be using it via @extends('layouts.mainlayout') . Currently it basically just crams the test.blade.php view into the mainlayout.blade.php layout.

It basically uses the mainlayout.blade.php template like this:

resources/views/layouts/mainlayout.blade.php

@section('content')
 Contents of view test.blade.php get crammed here
@stop

Answer 1

The good news is that your packages have access to the root directory of your laravel application by default!

When you create a package and publish a package in your Laravel Application/Project a fresh copy of the package resides in /vendor/package-name

The ACTUAL published package resides in your Laravel Application/Project in the normal locations just like if it was created from within the Application/Project!

For instance,

Your package's assets ie: css,js,images get published in the app's public folder

Laravel/App infrastructure:

App
   -Http
        -Controllers
                -AppController
                -PackageController 
   -Listeners
   -Console
public
   -assets
         -images
   -css
   -js
   -package-name
         -assets
                -images
         -css
         -js
resources
   -views
         -layouts
                -masterLayout.blade.php
                -partials
         -package-name
                -packageChildView.blade.php 
                -package-partials

As you can see, all of your packages can get to the layouts just fine /resources/views/ ! You can also get to public/ by default.

When taking over a large/unstructured project make sure you do a search on the file in question because you may be in for a surprise to find out that there are multiple copies of a file and the file your working on and in question may be the wrong one!

So in short,

The package will have access to the layouts in the application. When you publish your views they will look in two spots for the layouts/views by default .

Laravel actually registers two locations for your views: the application's resources/views/vendor directory and the directory you specify.

Answer 2

when extend a layout, by default Laravel will use layout from Laravel project project/resources/views/layouts/sample_layout.blade.php

@extend('layouts.sample_layout')

If we want to use package layout, assume your package layout like this

package_name/resources/views/layouts/pk_layout.blade.php

we have to use this

@extend('package_name::layouts.pk_layout')
