无法在laravel中提交表单数据

I am using laravel. Below is my form.

<h1>New Comment</h1>
<form method="post">

Comment: <input type="text" size="128" name="comment" value="{{old('body')}}" /></p>

    @if ($errors->has('body'))
    <p class="warning">Comment cannot be empty.</p>
    @endif

    <p><input type="submit" value="Submit" /> <input type="reset" value="Reset" /></p>
    {{ csrf_field() }}
</form>

My Route:

Route::post('/{id}', 'FilmsController@addComment')->name('addComment');

My controller:

public function addComment(Request $request)
{
    $request->validate([
        'body' => 'required',
    ]);

    $entry = new Comment();
    $entry->body = $request->body;
    $entry->save();

    return redirect('/');

My schema includes 'body'... $table->string('body');

I am seeing my warning message when I click submit. The same happens when trying to update as well as add a new comment.

我正在使用laravel。 下面是我的表格。 p> 

 ＆lt; h1＆gt;新评论＆lt; / h1＆gt; 
＆lt; form method =“post”＆gt; 
 
评论：＆lt; input type =  “text”size =“128”name =“comment”value =“{{old（'body'）}}”/＆gt;＆lt; / p＆gt; 
 
 @if（$ errors-＆gt; has（'  body'））
＆lt; p class =“warning”＆gt;评论不能为空。＆lt; / p＆gt; 
 @endif 
 
＆lt; p＆gt;＆lt; input type =“submit”value =“提交 “/＆gt;  ＆lt; input type =“reset”value =“Reset”/＆gt;＆lt; / p＆gt; 
 {{csrf_field（）}} 
＆lt; / form＆gt; 
  code>  pre> 
 
  
我的路线： p> 
 
 


  Route :: post（'/ {id}'，'FilmsController @ addComment'） - ＆gt; name（'addComment'）; 
   code>  pre> 
 
 
我的控制器： p> 
 
 


  public function addComment（Request $ request）
 {
 $ request-＆gt; 验证（[
'body'=＆gt;'required'，
]）; 
 
 $ entry = new Comment（）; 
 $ entry-＆gt; body = $ request-＆gt; body; 
  $ entry-＆gt; save（）; 
 
返回redirect（'/'）; 
  code>  pre> 
 
 
我的架构包括'body'...   $ table-＆gt; string（'body'）;  code>  p> 
 
 
点击提交后，我看到了警告信息。 尝试更新以及添加新评论时也会发生同样的情况。   p>

  • Because the element's name is comment, change this:

    'body' => 'required',

    To:

    'comment' => 'required',

    And this:

    $entry->body = $request->body;

    To:

    $entry->comment = $request->comment;

    Also, add an action to the form, for example:

    <form method="post" action="/add-comment">

    And the route should be:

    Route::post('add-comment', 'FilmsController@addComment')->name('addComment');

  • All you need to do is change the name="comment" to name="body" as you are validating and require the body field which the form doesn't have.

    <input type="text" size="128" name="body" value="{{old('body')}}" />
