我正在使用表单模型绑定,并使用fill()和save()方法更新数据库.
I'm using Form Model Binding as such and updating my DB using the fill() and save() methods.
{{ Form::model($account) }} {{ Form::text('name', null, array('class'=>'class')) }} {{ Form::text('email', null, array('class'=>'class')) }} {{ Form::password('password', array('class'=>'class')) }} {{ Form::password('password_confirmation', array('class'=>'class')) }} {{ Form::close() }}哪个触发了我的editAccount控制器方法:
Which fires my editAccount controller method:
$rules = array( 'name' => array('required'), 'email' => array('required'), 'password' => array('confirmed') ); $validator = Validator::make(Input::all(), $rules); if ($validator->fails()) { // Redirect } // Save to DB $account->fill(Input::all()); $account->save();这可以正常工作,但是如果未提供密码(因为用户不想更新/修改密码),则在数据库中将password字段设置为null.因此,如果表单中提供了新的密码值,我只希望密码字段更新.
Which works fine, but if no password was supplied (because the user doesn't want to update/modify it) then the password field is set to null in the db. So, I only want the password field to update if a new password value is supplied via the form.
我知道我可以执行以下操作:
I know I can do the following:
// Set the fields manually $account->name = Input::get('name'); $account->email = Input::get('email'); // Only update the password field if a value is supplied if (Input::get('password')) { $account->password = Input::get('password'); } $account->save();但是我想知道是否有更清洁的方法来处理此问题?就像Laravel/Eloquent中的UpdateOnlyIfValueExists()方法一样.
However I'm wondering if there is a more cleaner way to handle this? Like an UpdateOnlyIfValueExists() method within Laravel/Eloquent.
推荐答案使用Input::only('foo', 'bar')将仅获取完成请求所需的值-而不使用Input::all().
Using Input::only('foo', 'bar') will grab only the values needed to complete the request - instead of using Input::all().
但是,如果输入中不存在'foo'或'bar',则该键将以null的值存在:
However, if 'foo' or 'bar' doesn't exist within the input, the key will exist with the value of null:
$input = Input::only('foo', 'bar'); var_dump($input); // Outputs array (size=2) 'foo' => null 'bar' => null要以一种干净的方式进行过滤,请过滤任何具有null值的值:
To filter in a clean way, any values with a null value:
$input = array_filter($input, 'strlen');在您的示例中,它将替换为:$account->fill(Input::all());
In your example, this would replace: $account->fill(Input::all());
