# 页面内容
|
||
|
||
`laravel-admin`的布局可参考后台首页的布局文件[HomeController.php](https://github.com/z-song/laravel-admin/blob/master/src/Console/stubs/HomeController.stub)的`index()`方法。
|
||
|
||
`Encore\Admin\Layout\Content`类用来实现内容区的布局。`Content::body($content)`方法用来添加页面内容：
|
||
|
||
一个简单的后台页面代码如下：
|
||
|
||
```php
|
||
public function index()
|
||
{
|
||
return Admin::content(function (Content $content) {
|
||
|
||
// 选填
|
||
$content->header('填写页面头标题');
|
||
|
||
// 选填
|
||
$content->description('填写页面描述小标题');
|
||
|
||
// 添加面包屑导航 since v1.5.7
|
||
$content->breadcrumb(
|
||
['text' => '首页', 'url' => '/admin'],
|
||
['text' => '用户管理', 'url' => '/admin/users'],
|
||
['text' => '编辑用户']
|
||
);
|
||
|
||
// 填充页面body部分，这里可以填入任何可被渲染的对象
|
||
$content->body('hello world');
|
||
});
|
||
}
|
||
|
||
```
|
||
|
||
其中`$content->body();`方法可以接受任何可字符串化的对象作为参数，可以是字符串、数字、包含了`__toString`方法的对象，实现了`Renderable`、`Htmlable`接口的对象，包括laravel的视图。
|
||
|
||
|
||
## 布局
|
||
|
||
`laravel-admin`的布局使用bootstrap的栅格系统，每行的长度是12，下面是几个简单的示例：
|
||
|
||
添加一行内容:
|
||
|
||
```php
|
||
$content->row('hello')
|
||
|
||
---------------------------------
|
||
|hello |
|
||
| |
|
||
| |
|
||
| |
|
||
| |
|
||
| |
|
||
---------------------------------
|
||
|
||
```
|
||
|
||
行内添加多列：
|
||
|
||
```php
|
||
$content->row(function(Row $row) {
|
||
$row->column(4, 'foo');
|
||
$row->column(4, 'bar');
|
||
$row->column(4, 'baz');
|
||
});
|
||
----------------------------------
|
||
|foo |bar |baz |
|
||
| | | |
|
||
| | | |
|
||
| | | |
|
||
| | | |
|
||
| | | |
|
||
----------------------------------
|
||
|
||
|
||
$content->row(function(Row $row) {
|
||
$row->column(4, 'foo');
|
||
$row->column(8, 'bar');
|
||
});
|
||
----------------------------------
|
||
|foo |bar |
|
||
| | |
|
||
| | |
|
||
| | |
|
||
| | |
|
||
| | |
|
||
----------------------------------
|
||
|
||
```
|
||
|
||
列中添加行：
|
||
|
||
```php
|
||
$content->row(function (Row $row) {
|
||
|
||
$row->column(4, 'xxx');
|
||
|
||
$row->column(8, function (Column $column) {
|
||
$column->row('111');
|
||
$column->row('222');
|
||
$column->row('333');
|
||
});
|
||
});
|
||
----------------------------------
|
||
|xxx |111 |
|
||
| |---------------------|
|
||
| |222 |
|
||
| |---------------------|
|
||
| |333 |
|
||
| | |
|
||
----------------------------------
|
||
|
||
|
||
```
|
||
|
||
|
||
列中添加行, 行内再添加列：
|
||
|
||
```php
|
||
$content->row(function (Row $row) {
|
||
|
||
$row->column(4, 'xxx');
|
||
|
||
$row->column(8, function (Column $column) {
|
||
$column->row('111');
|
||
$column->row('222');
|
||
$column->row(function(Row $row) {
|
||
$row->column(6, '444');
|
||
$row->column(6, '555');
|
||
});
|
||
});
|
||
});
|
||
----------------------------------
|
||
|xxx |111 |
|
||
| |---------------------|
|
||
| |222 |
|
||
| |---------------------|
|
||
| |444 |555 |
|
||
| | | |
|
||
----------------------------------
|
||
```
