You can use the following code to trim all string input (as you might have arrays in the input)

<pre><code> // trim all input
 Input::merge(array_map(function ($value) {
 if (is_string($value)) {
 return trim($value);
 } else {
 return $value;
 }
 }, Input::all()));
</code></pre>

blocks|key|2447060|text|验证器不需要更改任何输入数据。trim验证器存在于CodeIgniter中，但对我来说，这不是执行Trim的正确位置。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2447061|您可以使用以下方法自动修剪所有输入：|2447062|Input::merge(array_map('trim',+Input::all()));|code-block|syntax|javascript|2447063|现在完成剩下的代码：|2447064|$username+=+Input::get('username');+//+it's+trimed+

It's not job for validator to change any input data. Trim validator exists in CodeIgniter, but as to me this isn't right place to perform trim.

You can automatically trim all input by using using this:

<pre class="lang-php prettyprint-override"><code>Input::merge(array_map('trim', Input::all()));
</code></pre>

Now do the rest of your coding:

<pre class="lang-php prettyprint-override"><code>$username = Input::get('username'); // it's trimed 
// ...
Validator::make(...);
</code></pre>

Due to the documention <a href="https://laravel.com/docs/5.8/requests#input-trimming-and-normalization" rel="noreferrer">laravel HTTP Request</a>
by default laravel trim all the requests data.

<hr>

and <code>Trim</code> the request in validation part is so dirty job.
You could manage this feature like <code>trim</code> or <code>convert empty string to null</code> with the <a href="https://laravel.com/docs/5.8/middleware" rel="noreferrer">middleware</a>

because middleware execute before the validation and you could have clean data in validation

blocks|key|1150346|text|在Laravel5.2或5.3中，您可以使用trim来删除这样的空格|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1150347|$input+=+array_map('trim',+$request->all());|offset|length|style|CODE|1150348|因此，这将删除张贴的所有空格表单输入，验证也会正常工作。|1150349|entityMap^0|0|0|18|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|M|8|@$D|N|E|O|F|G]]|9|@]|A|$]]|$1|H|3|I|5|6|7|P|8|@]|9|@]|A|$]]|$1|J|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|K|$]]

In Laravel 5.2 or 5.3 you can use trim for spaces remove like this

<code>$input = array_map('trim', $request-&gt;all());</code>

so this will remove all space form inputs that posted and validation will work fine

blocks|key|102574|text|您可以在请求文件中使用此方法。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|102575|$input+=+request()->all();

You can use this in your request file.

<pre><code>$input = request()-&gt;all();
$input['url'] = trim($input['url']);
request()-&gt;replace($input);
</code></pre>

You can also create an <code>all()</code> function in your request file to update request parameters:

<pre><code> public function all()
 {
 $all = parent::all(); // $this-&gt;all();
 $all['new_key'] = "new_data";
 $all['old_key'] = "new_data";

 return $all;
 }

I extended the <code>FormRequest</code> class and overrode the <code>prepareForValidation</code> method which is called before validation happens.

<pre><code>// anything I don't want trimmed here
protected $untrimmable = [];

// replace the request with trimmed request here
protected function prepareForValidation()
{
 return $this-&gt;replace($this-&gt;trimData($this-&gt;all()));
}

// recursively trim the fields in the request here
protected function trimData($data,$keyPrefix = '')
{
 $trimmedFields = array_map(function($value,$field) use ($keyPrefix){
 // if the value is an array handle it as
 // a request array and send along the prefix
 if(is_array($value)){
 return $this-&gt;trimData($value,$this-&gt;dotIndex($keyPrefix,$field));
 }

 // if the field is not in the specified fields to be
 // left untrimmed
 if(
 !in_array($this-&gt;dotIndex($keyPrefix,$field),$this-&gt;dontTrim) &amp;&amp; 
 !in_array($this-&gt;dotIndex($keyPrefix,$field), $this-&gt;untrimmable)
 ) {
 return trim((string) $value);
 }

 return $value;

 }, $data,array_keys($data));

 return array_combine(array_keys($data),$trimmedFields);
}
</code></pre>

What it does:

<ol>
<li>Replace request with a new one with trimmed inputs</li>
<li>Set all fields I don't want trimmed in an <code>untrimmable</code> property.</li>
<li>Handles nested inputs with dot notation . </li>
</ol>

I am a beginner in Laravel 5. 

How can I remove whitespaces in validator?? i have read the documentation but there is no validator for trim(remove whitespaces).

 'email' =&gt; 'required|email',
 'address' =&gt; 'required',
 'phones' =&gt; 'required'
 ];
