未定义变量: ip_address (视图：
未定义变量: ip_address (视图：
提问于 2015-01-02 12:29:23
我得到了一个未声明的变量错误，但不知道为什么。
我正在尝试实现全文搜索，并有以下代码
在我的控制器里
<?php
class PostsController extends BaseController {
public function postSearch(){
$q = Input::get('query');
$posts = ec2_instance::whereRaw("MATCH(instance_id,instance_type,availability_zone, status_checks,alarm_status, public_dns, key_name ) AGAINST(? IN BOOLEAN MODE)", array($q))->get();
return View::make('ec2_instance', compact('posts'));
$ip_address = public_ip::whereRaw("MATCH(ip_address ) AGAINST(? IN BOOLEAN MODE)",
array($q))->get();
return View::make('ec2_instance', compact('ip_address'));
}
}
?>在我看来
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">

<style>
@import url(//fonts.googleapis.com/css?family=Raleway:700);
body {

text-align:center;

}

position: absolute;

top: 50%;
margin-left: -150px;
margin-top: -100px;
}
a, a:visited {
text-decoration:none;
}
h1 {
font-size: 32px;
margin: 16px 0 0 0;
}
</style><div class="search">
{{ Form::model(null, array('route' => array('search'))) }}
{{ Form::text('query', null, array( 'placeholder' => 'Search query...' )) }}
{{ Form::submit('Search') }}
@foreach($posts as $post)
<li>{{ $post->instance_id }}</li>
<li>{{ $post->instance_type }}</li>
<li>{{ $post->availability_zone }}</li>
<li>{{ $post->status_checks }}</li>
<li> {{ $post->alarm_status }}</li>
<li> {{ $post->public_dns }}</li>
<li>{{ $post->key_name }}</li>
@endforeach
@foreach($ip_address as $pip)
<li>{{ $pip->ip_address }}</li>
@endforeach
{{ Form::close() }}
我只是不能因为我的生活而看到错误

你不能有两个返回语句。
return View::make('ec2_instance', compact('posts'));
$ip_address = public_ip::whereRaw("MATCH(ip_address ) AGAINST(? IN BOOLEAN MODE)",
array($q))->get();
return View::make('ec2_instance', compact('ip_address'));试试这个：
public function postSearch(){
$q = Input::get('query');
$posts = ec2_instance::whereRaw("MATCH(instance_id,instance_type,availability_zone, status_checks,alarm_status, public_dns, key_name ) AGAINST(? IN BOOLEAN MODE)", array($q))->get();
$ip_address = public_ip::whereRaw("MATCH(ip_address ) AGAINST(? IN BOOLEAN MODE)", array($q))->get();
return View::make('ec2_instance', compact('ip_address', 'posts'));

在postSearch方法中
public function postSearch()
{
$q = Input::get('query');
$posts = ec2_instance::whereRaw("MATCH(instance_id,instance_type,availability_zone, status_checks,alarm_status, public_dns, key_name ) AGAINST(? IN BOOLEAN MODE)", array($q))->get();
return View::make('ec2_instance', compact('posts'));
$ip_address = public_ip::whereRaw("MATCH(ip_address ) AGAINST(? IN BOOLEAN MODE)",
array($q))->get();
return View::make('ec2_instance', compact('ip_address'));
}您有两个返回状态
return View::make('ec2_instance', compact('posts'));
///...
return View::make('ec2_instance', compact('ip_address'));第一次返回语句之后的代码从未运行，$ip_address变量从未发送到视图。有点像
public function postSearch()
{
$q = Input::get('query');
$posts = ec2_instance::whereRaw("MATCH(instance_id,instance_type,availability_zone, status_checks,alarm_status, public_dns, key_name ) AGAINST(? IN BOOLEAN MODE)", array($q))->get();
//return View::make('ec2_instance', compact('posts'));
$ip_address = public_ip::whereRaw("MATCH(ip_address ) AGAINST(? IN BOOLEAN MODE)",
array($q))->get();
//return View::make('ec2_instance', compact('ip_address'));
return View::make('ec2_instance', [
'ip_address'=>$ip_address,
'posts'=>$post
]);
}可能是你想要的。
