私はJavaScriptを使用したフィールド検証を必要とするphpフォームに取り組んでいますが、私はこれの新しい人なので、phpでそれを使用する方法がわかりません。次のコードでそれをやろうとした方法

<?php

 session_start();
 // include_once('header.php');

?>

<div id="contentarea">

<div style="background-color:#3fa0c1;color:#FFF">
 <h2 style="color:#FFF"> Checkout </h2>
</div>
<br/>  
<h4> Welcome to Checkout. <br/>
Please fill in the fields below to complete your purchase! 
</h4><br/>


<form action=" " method="POST" name="Form" onsubmit="return ValidateForm();"  style="color:#000000; font-size:18px;" 

<?php switch ($_GET["checkoutType"]) {
        case "Guest":   echo 'action="guestCheckout.php"'; break;
        case "Register": echo 'action="registerCheckout.php"'; break;
    }
?>

正常に動作しているように見えますが、アラートボックスを表示する代わりに、各フィールドの検証が完了した後にエラーメッセージを表示する必要があります。

Validation Pluginを使用して、フォームの検証を効果的に管理できます。 http://bassistance.de/jquery-plugins/jquery-plugin-validation/

JavaScript の検証を試してみたい場合はadd div or span with display property none. そしてif error then in that span/div display block and show error in that div/span。たとえば、以下のコードを参照してください。

HTMLで

 <input  style="height:20px; margin-bottom:10px;"  name="name" size="40"/><br/>
<span id="name_error" style="display:none"></span>

JavaScriptで

<script>
function ValidateForm()
{
   var name = document.Form.name;

  if(name.value == ''){
    document.getElementById('name_error').innerHTML = 'Please provide name!';
    document.getElementById('name_error').style.display = 'block';        
    name.focus();
    return false;
  }else{
    document.getElementById('name_error').innerHTML = '';
    document.getElementById('name_error').style.display = 'none';        
  }
 }
</script>

これを試してください。うまくいくことを願っています。ここで、そのフィールドにエラーが存在する場合は、そのスパンにエラーを表示します。それ以外の場合は、何も表示しません。

タク。
