Question

我有点难过为什么表单数据没有从下面的代码提交到数据库中。我对Laravel 4有点新鲜，我猜测我在代码的某个地方错过了一个电话。当我单击提交时，我重新路由但该条目未添加到数据库中。在指出我缺少的内容时，将不胜感激。非常感谢你。

EntriesController.php

<?php

class EntriesController extends BaseController {

#Handles "GET /" request
public function getIndex()
{
    return View::make('home')->with('entries', Entry::all());
}   

#Handles "POST /" request
public function postIndex()
{
    $entry = array(
        'username' => Input::get('frmName'),
        'email'    => Input::get('frmEmail'),
        'comment'  => Input::get('frmComment')
    );

// save the guestbook entry to the database
Entry::create($entry);

return Redirect::to('/');
}
}

?>

home.blade.php

<html>
<head>
    <title>Laravel 4 Guestbook</title>

<body>
    @foreach ($entries as $entry)
        <p>{{ $entry->comment }}</p>
        <p>Posted on {{ $entry->created_at->format('M jS, Y') }} by 
           <a href="mailto:{{ $entry->email }}">{{ $entry->username}}</a>

    <form action="/" method="post">

            <tr>
                <td>Name</td>
                <td><input type="text" name="frmName" value="" size="30" maxlength="50"></td>
            </tr>

            <tr>

Entry.php

<?php

class Entry扩展了Eloquent {

   /**
     * The database table used by the model.
     *
     * @var string
     */
    protected $table = 'entries';

}

?>

routes.php文件

Route::controller('/', 'EntriesController');

Answer 1

看起来您的表单操作指向错误的位置。＆＃39; /＆＃39;路径是您的getIndex()路线。我相信它应该是：

  <form action="postIndex" method="post">
        <table border="0">
            <tr>
                <td>Name</td>
                <td><input type="text" name="frmName" value="" size="30" maxlength="50"></td>
            </tr>

试试这个：

<强> EntriesController.php

<?php

class EntriesController extends BaseController {


    public function index()
    {

        $entries = Entry::all();

        //->with('entries', Entry::all());
        //in Laravel 4.1, variable pass with 'With' will be process via Session.
        // changed 'with' to 'compact'

        return View::make('home', compact('entries'));
    }   


    public function store()
    {
        $entry = array(
            'username' => Input::get('frmName'),
            'email'    => Input::get('frmEmail'),
            'comment'  => Input::get('frmComment')
        );

        // save the guestbook entry to the database
        Entry::create($entry);

        // Name route `index`
        // resourceful controller create 7 routes for you
        // http://laravel.com/docs/controllers#resource-controllers

        return Redirect::route('index');
    }
}

<强> routes.php文件

Route::resource('/', 'EntriesController');

<强> home.blade.php

<html>
<head>
    <title>Laravel 4 Guestbook</title>
</head>
<body>
    @foreach ($entries as $entry)
        <p>{{ $entry->comment }}</p>
        <p>Posted on {{ $entry->created_at->format('M jS, Y') }} by 
           <a href="mailto:{{ $entry->email }}">{{ $entry->username}}</a>
        </p><hr>
    @endforeach

    {{ Form::open(array('route' => 'store')) }}
        <table border="0">
            <tr>
                <td>Name</td>
                <td><input type="text" name="frmName" value="" size="30" maxlength="50"></td>
            </tr>

            <tr>
                <td>Email</td>
                <td><input type="text" name="frmEmail" value="" size="30" maxlength="100"></td>
            </tr>
            <tr>
                <td>Comment</td>
                <td><input textarea name="frmComment" row="5" cols="30"></textarea></td>
            </tr>

            <tr>
                <td></td>
                <td>
                    <input type="submit" name="submit" value="submit"> 
                    <input type="reset" name="reset" value="reset">
