在同一个html页面

Question

我有我在我的页面上使用的表单，以便客户能够向我发送一些消息。一切都好，工作正常。缺少的一件事是每个表单错误和结果（电子邮件类型错误，名字缺失）都显示在新页面上。我希望在同一页面上有通知，结果还有例如“你的消息已被发送”。我在一些页面中看到，如果输入错误的话，表格输入可以是红色的高亮度等等。我读到这可以通过ajax或jquery来完成，但说实话，我不是那么熟悉它。在我的解决方案中我使用bootstrap和php。你能帮我实现吗？在我当前的代码下面。

html（使用bootstrap）：

<form action="send_form_email.php" method="post" class="form-horizontal">
              <div class="form-group">
                <label for="first_name" class="col-lg-2 control-label">First name</label>
                <div class="col-lg-10">
                <input type="text" class="form-control" id="first_name" name="first_name" placeholder="Enter you first name">
                </div>
              </div><!-- End form group -->

               <div class="form-group">
                <label for="last_name" class="col-lg-2 control-label">Last name</label>
                <div class="col-lg-10">
                  <input type="text" class="form-control" id="last_name" name="last_name" placeholder="Enter you last name">
                </div>
              </div><!-- End form group -->

              <div class="form-group">
                <label for="email" class="col-lg-2 control-label">Email</label>
                <div class="col-lg-10">
                  <input type="text" class="form-control" id="email" name="email" placeholder="Enter you Email Address">
                </div>
              </div><!-- End form group -->

              <div class="form-group">
                <label for="telephone" class="col-lg-2 control-label">Telephone</label>
                <div class="col-lg-10">
                  <input type="text" class="form-control" id="telephone" name="telephone" placeholder="Enter you phone number">
                </div>
              </div>

              <div class="form-group">
                <label for="comments" class="col-lg-2 control-label">Any Message</label>
                <div class="col-lg-10">
                  <textarea name="comments" id="comments" name="comments" class="form-control" 
                  cols="20" rows="10" placeholder="Enter your Message"></textarea>
                </div>
              </div> 

              <div class="form-group">
                <div class="col-lg-10 col-lg-offset-2">
                  <button type="submit" class="btn btn-primary">Submit</button>
                </div>
              </div>



            </form>

这是处理电子邮件发送和表单验证的php：

<?php
if(isset($_POST['email'])) 
{

    // CHANGE THE TWO LINES BELOW
    $email_to = "myemail@gmail.com";

    $email_subject = "Nowy formularz od osoby";


    function died($error) {
        // your error code can go here
        echo "We are very sorry, but there were error(s) found with the form you submitted. ";
        echo "These errors appear below.<br /><br />";
        echo $error."<br /><br />";
        echo "Please go back and fix these errorsbr /><br />";
      echo '<input type="button" value="BACK" onclick="history.back();">'; 
        die();
    }

    // validation expected data exists
    if(!isset($_POST['first_name']) ||
        !isset($_POST['last_name']) ||
        !isset($_POST['email']) ||
        !isset($_POST['telephone']) ||
        !isset($_POST['comments'])) {
        died('We are sorry, but there appears to be a problem with the form you submitted.');       
    }

    $first_name = $_POST['first_name']; // required

    $email_from = $_POST['email']; // required

    $error_message = "";
    $email_exp = '/^[A-Za-z0-9._%-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/';
  if(!preg_match($email_exp,$email_from)) {
    $error_message .= The Email Address you entered does not appear to be valid.<br />';
  }
    $string_exp = "/^[A-Za-z .'-]+$/";
  if(!preg_match($string_exp,$first_name)) {
    $error_message .= 'The First Name you entered does not appear to be valid.<br />';
  }
  if(!preg_match($string_exp,$last_name)) {
    $error_message .= 'The Last Name you entered does not appear to be valid.<br />';
  }
  if(strlen($comments) < 2) {
    $error_message .= 'The Comments you entered do not appear to be valid.<br />';
  }
  if(strlen($error_message) > 0) {
    died($error_message);
  }
    $email_message = "Zawartosc wypelnionego formularza\n\n";

    function clean_string($string) {
      $bad = array("content-type","bcc:","to:","cc:","href");
      return str_replace($bad,"",$string);
    }

    $email_message .= "First Name: ".clean_string($first_name)."\n";
    $email_message .= "Last Name: ".clean_string($last_name)."\n";
    $email_message .= "Email: ".clean_string($email_from)."\n";
    $email_message .= "Telephone: ".clean_string($telephone)."\n";
    $email_message .= "Comments: ".clean_string($comments)."\n";


// create email headers
$headers = 'From: '.$email_from."\r\n".
'Reply-To: '.$email_from."\r\n" .
'X-Mailer: PHP/' . phpversion();
if(mail($email_to, $email_subject, $email_message)) {

 echo '<input type="button" value="BACK" onclick="history.back();">'; 
 }else{ 

         echo "Nie wyslano z z powodu nieznanego bledu prosze sprobuj ponownie lub zadzwon do mnie bezposrednio | Form was not send due to unknown reason please go back and try again if it would not help please try to rich me directly on my phone.<br/><br/><br/><br/>";
      echo '<input type="button" value="BACK" onclick="history.back();">'; 

}
}

Answer 1

从

更改

<form action="send_form_email.php" method="post" class="form-horizontal">

要

<form action="" method="post" class="form-horizontal">

然后将您的HTML文件另存为PHP，并将PHP代码添加到表单页面

之前

更新了自定义样式错误消息的PHP代码。

<?php
if(isset($_POST['email'])) 
{

    // CHANGE THE TWO LINES BELOW
    $email_to = "myemail@gmail.com";

    $email_subject = "Nowy formularz od osoby";


    function died($error)
    {
        // your error code can go here
        // Adding bootstrap style class
        echo '<div class="alert alert-warning" role="alert">';
        echo "We are very sorry, but there were error(s) found with the form you submitted. ";
        echo "These errors appear below.<br /><br />";
        echo $error."<br /><br />";
        //Not needed any more
        //echo "Please go back and fix these errorsbr /><br />";
        //echo '<input type="button" value="BACK" onclick="history.back();">';
