无法在laravel中提交表单数据

Question

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.

Answer 1

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');
