Php 多多拉威尔
我有三张桌子Php 多多拉威尔,php,laravel,laravel-4,eloquent,Php,Laravel,Laravel 4,Eloquent,我有三张桌子 职位 类别 职类职位 我想在我的category_post表中添加category_id和post_id，以创建包含类别的帖子。我有类别的复选框 主要主题是，我想创建多个类别的职位。所以我想在category_post表中添加category_id和post_id 拉威尔有可能吗 我看过很多教程，现在我累了。请帮帮我 请参阅下面的代码 我的迁移表： <?php use Illuminate\Database\Migrations\Migration; use Illumi
<?php
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
class CreateCategoriesTable extends Migration {
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('categories', function(Blueprint $table) {
$table->increments('id');
$table->string('name');
$table->string('category_slug');
$table->timestamps();
});
}
public function up()
{
Schema::create('posts', function(Blueprint $table) {
$table->increments('id');
$table->string('title');
$table->string('slug');
$table->string('meta');
$table->text('body');
$table->string('image');
$table->timestamps();
});
}
public function up()
{
Schema::create('category_post', function(Blueprint $table) {
$table->increments('id');
$table->integer('category_id')->unsigned()->index();
$table->foreign('category_id')->references('id')->on('categories')->onDelete('cascade');
$table->integer('post_id')->unsigned()->index();
$table->foreign('post_id')->references('id')->on('posts')->onDelete('cascade');
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::drop('categories');
}
public function down()
{
Schema::drop('posts');
}
public function down()
{
Schema::drop('category_post');
}
}
首先，您需要一个类别ID数组：
// view
@foreach ($categories as $category)
{{ Form::checkbox('categories[]', $category->id, $post->categories->contains($category->id)) }}
{{ Form::label($category->name) }}
@endforeach
如果在编辑时使用模型绑定，则将类别[]
重命名为其他名称以避免字段名冲突
然后，您需要将帖子与这些类别同步：
// posts controller @store
... // validate everything, categories too
$categories = Input::get('categories');
$post = Post::create($data);
$post->categories()->sync($categories);
return Redirect::route('admin.posts.index');
标记为正确答案，如果它让其他人知道。你好deczo，现在我可以创建帖子。但是当我试图编辑这篇文章时，类别没有被选中。但这是需要的。如何从透视表中设置复选框类别的值？这意味着，我想显示我在帖子中选择的类别。请帮助我。请检查我的编辑-3rd参数，以便Form:：checkbox（）
将完成此工作。如果给定的类别在文章的类别集合中，它将检查该字段。谢谢回答。我加了这个。但当我试图编辑文章时，只能选中第一个复选框。其他人不。。怎么办。？请1检查我的编辑，应该有contains
nothas
方法，2确保类别
字段名中没有冲突
