Question

我正在尝试将表单添加到我的wordpress页面，但我现在遇到的问题是，只要页面在我的网页上访问，表单就会向我发送电子邮件。我认为这是因为我已经将php放在头文件中，所以每次加载头都会发送一封电子邮件。如何让它只在实际填写时发送表单提交电子邮件？

HTML

 <form name="infoform" method="post" action="" >

  <br><input type="text" name="ffirstname" placeholder="First Name"/><input type="text" name="lastname" placeholder="Last Name"/>
  <br><br><input type="text" name="address" placeholder="Address"/><input type="text" name="unit" placeholder="Unit"/></br>
  <br><input type="text" name="city" placeholder="City"/><select name="province" >
<option value="ab">AB</option>
  <option value="BC">BC</option> 
  <option value="BC">MB</option>
  <option value="NB">NB</option>
<option value="NL">NL</option>
<option value="NS">NS</option>
<option value="ON">ON</option>
<option value="PE">PE</option>
<option value="QC">QC</option>
<option value="SK">SK</option>
</select><input type="text" name="postal" placeholder="Postal Code"/></br>
<br><input type="text" name="country" placeholder="Country"/></br>
<Br><input type="text" name="email" placeholder="Email"/><input type="number" name="phone" placeholder="Phone#"/></br>
<br> <br><input class="submit" type="submit" value="Next" />

CSS

  <style>

  input[type=text], input[type=number], select[name=province]{ font-family: arial; width:100%;  
  border: 1px solid #E5E5E5; padding: 10px 20px;}
input[name=ffirstname] {width:49%; margin-right:1%; }
input[name=lastname] {width:49%; margin-left:1%; }
input[name=address] {width:65.6667%; margin-right:1%; }
input[name=unit] {width:32.3337%; margin-left:1%; }
input[name=city] {width:49%; margin-right:1%; }
select[name=province] {width:24%; margin-left:1%;}
input[name=postal] {width:24%; margin-left:1%; }
input[name=email] {width:49%; margin-right:1%; }
input[name=phone] {width:49%; margin-left:1%;}

input[class=submit] {

  background-color: #f05a28;
  color: white;
  padding: 8px 20px;
  margin-left: 85%;
  border-radius: 4px;
  border: none; !important;
  outline: none; !important ;
  cursor: pointer;
  box-shadow: none; !important;}

PHP

<?php

$name = $_POST['ffirstname'];
$lastname = $_POST['lastname'];
$address = $_POST['address'];
$unit = $_POST['unit'];
$city = $_POST['city'];
$province = $_POST['province'];
$postal = $_POST['postal'];
$country = $_POST['country'];
$email = $_POST['email'];
$phone = $_POST['phone'];
$formcontent=" From: $name $lastname \n Address: $address 
\n Unit: $unit \n City: $city \n Province: $province \n 
Postal Code: $postal \n Country: $country \n 
Email: $email \n Phone: $phone \n ";
$recipient = "contact@justhired.ca";
$subject = "Contact Form";
$mailheader = "From: $email \r\n";
mail($recipient, $subject, $formcontent, $mailheader) or die("Error!");

?>

Answer 1

您需要检查提交是否已设置且输入是否为空。

旁注：您可以添加其余的POST数组，并为您的<input class="submit" type="submit" value="Next" />命名：

<input class="submit" name="submit" type="submit" value="Next" />

示例：

if(isset($_POST['submit'])) {

if
    (
    !empty($_POST['ffirstname'])
    && 
    !empty($_POST['lastname']) 

    // ... and any other inputs you wish to check for.

    )
{

    $name = $_POST['ffirstname'];
    $lastname = $_POST['lastname'];
    $address = $_POST['address'];
    $unit = $_POST['unit'];
    $city = $_POST['city'];
    $province = $_POST['province'];
    $postal = $_POST['postal'];
    $country = $_POST['country'];
    $email = $_POST['email'];
    $phone = $_POST['phone'];
    $formcontent=" From: $name $lastname \n Address: $address 
    \n Unit: $unit \n City: $city \n Province: $province \n 
    Postal Code: $postal \n Country: $country \n 
    Email: $email \n Phone: $phone \n ";
    $recipient = "contact@justhired.ca";
    $subject = "Contact Form";
    $mailheader = "From: $email \r\n";
    mail($recipient, $subject, $formcontent, $mailheader) or die("Error!");

    }

}

<form name="infoform" method="post" action="" >是您在电子邮件中获取空值的主要原因，因为您在与PHP处理器相同的文件中使用整个代码而不检查是否有任何输入是否空。

<?php
if(isset($_POST['submit'])){
$name = $_POST['ffirstname'];
$lastname = $_POST['lastname'];
$address = $_POST['address'];
$unit = $_POST['unit'];
$city = $_POST['city'];
$province = $_POST['province'];
$postal = $_POST['postal'];
$country = $_POST['country'];
$email = $_POST['email'];
$phone = $_POST['phone'];
$formcontent=" From: $name $lastname \n Address: $address 
\n Unit: $unit \n City: $city \n Province: $province \n 
Postal Code: $postal \n Country: $country \n 
Email: $email \n Phone: $phone \n ";
$recipient = "contact@justhired.ca";
$subject = "Contact Form";
$mailheader = "From: $email \r\n";
mail($recipient, $subject, $formcontent, $mailheader) or die("Error!");
}
?>

根据Fred的建议，您需要检查表单是否已提交并将提交按钮更改为

<input class="submit" type="submit" name="submit" value="Next" />

Answer 3

正在发生的事情是每次页面加载时您的PHP脚本都在运行。您需要在PHP中包含一个条件语句：“单击此按钮时，请执行此操作...”

为了实现这一目标，您需要更新HTML并将name属性添加到提交按钮。我给该属性赋值为'Next'。你总是可以改变它。但是，请确保更改反映在PHP脚本中。

<br> <br><input name="Next" class="submit" type="submit" value="Next" />

然后在PHP脚本中，以下内容将包装整个脚本：

if(isset($_POST['Next'])){
//Your script goes here
}

表单提交在每次访问页面后发送空白信息
