将验证与Recaptcha（或必填字段）集成

标签： php html forms recaptcha required

我在下面有一个表格，我希望根据不同的内容制作某些字段。

  1. 我希望以下字段是一个直接的必填字段，如果没有填写则会显示弹出提示：

    • 名称
    • 电子邮件

  2. 如果勾选手机，我想要手机字段。

  3. 如果勾选了帖子，则需要提供地址。

    4. 如果缺少某些内容但是如果一切正常，我如何弹出警报？然后发送表单？

    <div id="contactform">
 <script type="text/javascript">
 var RecaptchaOptions = {
    theme : 'white'
 };
 </script>
 <form class="form" method="POST" action="<?php the_permalink(); ?>" onsubmit="return validateCaptcha()">
<input type="hidden" name="valid" value="0" />

    <table border="0" style="float:left;" width="490">

您已在代码中找到答案：

<script type="text/javascript">
function validateCaptcha()
{
    if ($('input[name="valid"]')) return true;
    if ($('input[name="recaptcha_response_field"]').val() == "")
    {
        alert("Please complete the CAPTCHA field.");
        return false
    }

在此之后添加您自己的需求：

if ( phone == 'what it needs to be' )
{

  if( email == 'asdasd' ) {
      // all is good
  } else {
    alert( 'need email too' );
  }
  return true;
}
else 
{
  alert('Blah blah wrong phone');
  return false;
}

给你一个快速的例子：

表格

<html>
  <body>
    <form action="#" method="POST">
      <input id="email" type="text" value="" />
        <a id="submit" href="#">Submit Form</a>
    </form>
  </body>
</html>

Jquery部分：

$(document).ready(function(){
  $('a#submit').click(function(event){
      event.preventDefault();
      validateEmail();
  })
});

function validateEmail(){
  //declarations
  rule = /^[a-zA-Z0-9._-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,4}$/;

  //check
  if ($('input#email').val() === '' || !rule.test($('input#email').val())){
      alert ('That is not a Valid Email Address !');
      return false;
  } else {
      alert('validation passed! Submit the form !');
      //submit the form action here
  }
}
