Question

我有一个简单的php联系表单，我从网络教程中获得。它昨天工作，但今天不会工作。我喜欢一些帮助，因为我不知道php。

PHP：

<?php
//If the form is submitted
if(isset($_POST['submit'])) {

  //Check to make sure that the name field is not empty
  if(trim($_POST['contactname']) == '') {
    $hasError = true;
  } else {
    $name = trim($_POST['contactname']);
  }


  //Check to make sure that the subject field is not empty
  if(trim($_POST['subject']) == '') {
    $hasError = true;
  } else {
    $subject = trim($_POST['subject']);
  }

  //Check to make sure sure that a valid email address is submitted
  if(trim($_POST['email']) == '')  {
    $hasError = true;
  } else if (!filter_var( trim($_POST['email'], FILTER_VALIDATE_EMAIL ))) {
    $hasError = true;
  } else {
    $email = trim($_POST['email']);
  }

  //Check to make sure comments were entered
  if(trim($_POST['message']) == '') {
    $hasError = true;
  } else {
    if(function_exists('stripslashes')) {
      $comments = stripslashes(trim($_POST['message']));
    } else {
      $comments = trim($_POST['message']);
    }
  }

  //If there is no error, send the email
  if(!isset($hasError)) {
    $emailTo = 'person@domain.com'; // Put your own email address here
    $body = "Name: $name \n\nEmail: $email \n\nSubject: $subject \n\nComments:\n $comments";
    $headers = 'From: My Site <'.$emailTo.'>' . "\r\n" . 'Reply-To: ' . $email;

    mail($emailTo, $subject, $body, $headers);
    $emailSent = true;
  }
}
?>

HTML：

<form role="form" method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>" id="contactform">
                <?php if(isset($hasError)) { //If errors are found ?>
                  <p class="alert alert-danger">Please check if you've filled all the fields with valid information and try again. Thank you.</p>
                <?php } ?>

                <?php if(isset($emailSent) && $emailSent == true) { //If email is sent ?>
                  <div class="alert alert-success">
                    <p><strong>Message Successfully Sent!</strong></p>
                    <p>Thank you for using our contact form, <strong><?php echo $name;?></strong>! Your email was successfully sent and we&rsquo;ll be in touch with you soon.</p>
                  </div>
                <?php } ?>

                <div class="form-group">
                  <label for="name">Your Name<span class="help-required">*</span></label>
                  <input type="text" name="contactname" id="contactname" value="" class="form-control required" role="input" aria-required="true" />
                </div>

                <div class="form-group">
                  <label for="email">Your Email<span class="help-required">*</span></label>
                  <input type="text" name="email" id="email" value="" class="form-control required email" role="input" aria-required="true" />
                </div>

                <div class="form-group">
                  <label for="subject">Subject<span class="help-required">*</span></label>
                  <input type="text" name="email" id="subject" class="form-control required" role="input" aria-required="true">
                </div>

                <div class="form-group">
                  <label for="message">Message<span class="help-required">*</span></label>
                  <textarea rows="8" name="message" id="message" class="form-control required" role="textbox" aria-required="true"></textarea>
                </div>

                <div class="actions">
                  <input type="submit" value="Send Your Message" name="submit" id="submitButton" class="btn btn-grey" title="Click here to submit your message!" />
                  <input type="reset" value="Clear Form" class="btn btn-grey pull-right" title="Remove all the data from the form." />
                </div>
            </form>

它挂起了验证。不知道为什么。

Answer 1

$ _ POST [＆＃34; subject]未在您的表单中定义。您的SUBJECT字段称为EMAIL：

变化：

<div class="form-group">
  <label for="subject">Subject<span class="help-required">*</span></label>
  <input type="text" name="email" id="subject" class="form-control required" role="input" aria-required="true">
</div>

使用：

<div class="form-group">
  <label for="subject">Subject<span class="help-required">*</span></label>
  <input type="text" name="subject" id="subject" class="form-control required" role="input" aria-required="true">
</div>

PHP联系表格不会提交
