多くのチュートリアルを検索して読んでみましたが、ほとんどのチュートリアルはまったく役に立ちません。

誰かが私を実際のチュートリアルに向けて正しい方向に向けたり、私が間違ったことを教えてくれませんか.

私はスペースを削除しようとしましたが、私はそれを行う方法が100％ではありません。

$str = str_replace(" ", "", $str);

すべてのスペースを削除します。

さらに、私の PHP は少し錆びていstripslashesますが、逆のことaddslashesはしません。

したがって、探しているのは「フォームの検証」です。

有効なものの概念を確認しない限り、入力を受け入れたくありません。

検証を確認できるレベルは 2 つあります。1 つはクライアント側 (javascript を使用) で、もう 1 つはサーバー側です。

クライアント側では、jQuery フォーム検証プラグインのようなものを使用できます。

http://docs.jquery.com/Plugins/Validation

サーバー側では、substr_count() 関数を使用できます。

スペースだけの場合は、str_replace を使用します

$string = str_replace(' ', '', $string);

すべての空白には、preg_replace を使用します

$string = preg_replace('/\s+/', '', $string);

str_replace(' ', '', $string) を実行します。これは「ユーザー名」を取得し、ユーザー名を返します。ユーザーに実行させたくない場合を除き、php で実行するのが最も簡単です。次に、javascript を使用します。

function checkform(){
  var username = $('form[name = username]').val()
  var re =  /\s/g;
  if(re.test(username)){
   alert("You can't have a space") 
   return false;
   }
  }

説明するには: まず、ユーザー名の入力値を取得し、それを変数に入れます。次に、ユーザー名をテストして、スペース /s が含まれているかどうかを確認します。スペースがある場合は、警告します。var re は、test メソッドを使用して文字列内のスペースをチェックします。Return False は、フォームの送信を停止します。あなたは次のようになります

<form onsubmit="checkfrom()">

それはそれを説明するのに役立ちますか。記憶で作っているので違うかもしれません。

関数トリムが機能するはずです。:)
