Question

我的网站上有一个表单，其中添加了选择下拉列表。我选择选项，如果我们单击最后一个选项，将打开一个文本框。如果我们选择其他选项，则此文本框将被隐藏。在发送邮件时，如果用户单击其他选项（最后一个选项除外），则邮件正在发送，但也采用该自定义文本框值。仅当我单击最后一个选项时，此值才应发送。否则它将隐藏。怎么做，请帮帮我。这是我的代码

<form action="inc/contact.php" method="POST" class="theme-form-one form-validation" autocomplete="off">

  <input type="text" placeholder="Name *" name="name">
  <input type="text" placeholder="Phone *" name="phone">
  <input type="email" placeholder="Email *" name="email">

    <select id="contact-services" name="services" onchange='CheckServices(this.value);'>

      <option value=""> Services Interested</option>
      <option value="3D Modeling">3D Modeling</option>
      <option value="3D Rendering">3D Rendering</option>
      <option value="3D Animation">3D Animation</option>
      <option value="Custom">Custom Requirement</option>

    </select>

  <input type="text" name="service" id="service" style='display:none;'/>
  <textarea placeholder="Message" name="message"></textarea>
  <button class="theme-button-four btn3">SEND MESSAGE</button>

</form>

这是我的JavaScript

<script type="text/javascript">

function CheckServices(val){

  var element=document.getElementById('service');

  if(val=='Services Interested'||val=='Custom')
  element.style.display='block';
  else  
    element.style.display='none';
  }

</script>

这是我发送邮件的php代码

<?php

$to = "abc@mail.com";
$from = $_REQUEST['email'];
$name = $_REQUEST['name'];
$headers = "From: $from";
$subject = "subject";

$fields = array();
$fields{"name"}    = "Name";
$fields{"email"}    = "Email";
$fields{"phone"}    = "Phone";
$fields{"services"} = "Services";
$fields{"service"}    = "Service";
$fields{"message"}   = "Message";

$body = "Message:\n\n"; foreach($fields as $a => $b){   $body .= sprintf("%20s: %s\n",$b,$_REQUEST[$a]); }

$send = mail($to, $subject, $body, $headers);

Answer 1

onSubmit(){
    if (this.data.selected === 'embargoed') {
        this.data.date = this.date;
    }
}

这可能会对您有所帮助。代码的问题是即使$fields = array(); $fields{"name"} = "Name"; $fields{"email"} = "Email"; $fields{"phone"} = "Phone"; $fields{"services"} = "Services"; if(isset($_POST["service"]) && !empty($_POST["service"])) $fields{"service"} = "Service"; $fields{"message"} = "Message";为空，您也要推送数组。这就是为什么它包含在您的邮件正文中。因此，您只需放置一个service条件以确保if的值不为空

Answer 2

您要执行的操作是检查services文本框中是否包含特定值。如果包含，则我们可以包含它，也可以不包含它。我还整理了一下您的代码。

尝试一下：

$to = "abc@mail.com";
$from = $_POST['email'];
$name = $_POST['name'];
$headers = "From: $from";
$subject = "subject";

if(isset($_POST['services']) && $_POST['services'] != 'Custom'){

unset($_POST['service']);

}

$body = "Message:\n\n";

foreach($_POST as $a => $b){
$body .= sprintf("%20s: %s\n", ucfirst($a), $_POST[$a]);
 }

$send = mail($to, $subject, $body, $headers);

Answer 3

<script type="text/javascript">
   function CheckServices(val){
      var element=document.getElementById('service');
      if(val=='Services Interested'||val=='Custom')
          element.style.display='block';
      else  
       element.style.display='none';
       element.value = ''; // reset element value
     }
</script>

  Check element on php code
  if(!empty($_POST['service']) {
     // post data in mmail
  }

选择一个选项时不发送文本框值
