模板赋值
除了系统变量和配置参数输出无需赋值外，其他变量如果需要在模板中输出必须首先进行模板赋值操作，绑定数据到模板输出有三种方式：
assign方法
namespace indexappcontroller;
class Index extends hinkController
{
public function index()
{
// 模板变量赋值
$this->assign('name','ThinkPHP');
$this->assign('email','thinkphp@qq.com');
// 或者批量赋值
$this->assign([
'name' => 'ThinkPHP',
'email' => 'thinkphp@qq.com'
]);
// 模板输出
return $this->fetch('index');
}
}
class Index extends hinkController
{
public function index()
{
// 模板变量赋值
$this->assign('name','ThinkPHP');
$this->assign('email','thinkphp@qq.com');
// 或者批量赋值
$this->assign([
'name' => 'ThinkPHP',
'email' => 'thinkphp@qq.com'
]);
// 模板输出
return $this->fetch('index');
}
}
传入参数方法
方法fetch 及 display 均可传入模版变量，例如
namespace appindexcontroller;
class Index extends hinkController
{
public function index()
{
return $this->fetch('index', [
'name' => 'ThinkPHP',
'email' => 'thinkphp@qq.com'
]);
}
}
class Index extends hinkController
{
public function index()
{
return $this->fetch('index', [
'name' => 'ThinkPHP',
'email' => 'thinkphp@qq.com'
]);
}
}
class Index extends hinkController
{
public function index()
{
$content = '{$name}-{$email}';
return $this->display($content, [
'name' => 'ThinkPHP',
'email' => 'thinkphp@qq.com'
]);
}
}
{
public function index()
{
$content = '{$name}-{$email}';
return $this->display($content, [
'name' => 'ThinkPHP',
'email' => 'thinkphp@qq.com'
]);
}
}
对象赋值
class Index extends hinkController
{
public function index()
{
$view = $this->view;
$view->name = 'ThinkPHP';
$view->email = 'thinkphp@qq.com';
// 模板输出
return $view->fetch('index');
}
}
{
public function index()
{
$view = $this->view;
$view->name = 'ThinkPHP';
$view->email = 'thinkphp@qq.com';
// 模板输出
return $view->fetch('index');
}
}
助手函数
如果使用view助手函数渲染输出的话，可以使用下面的方法进行模板变量赋值：
return view('index', [
'name' => 'ThinkPHP',
'email' => 'thinkphp@qq.com'
]);
'name' => 'ThinkPHP',
'email' => 'thinkphp@qq.com'
]);
