php - Integrating validation with Recaptcha (or required fields)

Question

I have a form below that I want to make certain fields required based on different things.

I want the following fields to be a straight forward required field with a popup alert if they're not filled in:
- Name
- Email
I want the phone field to be required if phone is ticked.
Address to be required if post is ticked.

How can I make the alert's pop up if things are missing but if everything is ok then send the form?

<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">

Okie 给你一个简单的例子：

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
  }
}

您已经在代码中找到了答案：

<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;
}

等等
