Question

我有一个包含联系表单的html页面。我还没有使用验证码，但我试图了解为什么这段代码在进入之前没有工作。所以，我的index.html有这样的形式：

<form id="quote-form" action="inc/sendmail.php" method="post">
            <div class="sec-title text-center">
                <h1>Request for Quote</h1>
                <span class="border center"></span>
            </div>
            <div class="row">
                <div class="col-md-12">
                    <input type="text" name="name" value="" placeholder="Your Name*" required="">
                    <input type="email" name="email" value="" placeholder="Your Mail*" required="">
                    <input type="text" name="phone" value="" placeholder="Your Phone*" required="">
                    <select class="selectmenu" name=message>
                        <option selected="selected">Select Service</option>
                        <option value="Need Quote on a product Alpha</option>
                        <option>Other</option>
                    </select>
                    <button class="thm-btn bg-clr1" type="submit">Get a Quote</button>
                </div>  
            </div>    
        </form>

我的sendmail.php有以下代码：

<?php
if(isset($_POST['submit'])){
$name = $_POST['name'];
$email = $_POST['email'];
$message = $_POST['message'];
$phone = $_POST['phone'];
$formcontent="From: $name \n Message: $message \n Email:$email \n Phone:$phone";
$recipient = "testname@gmail.com";
$subject = "Website Contact Form";
$mailheader = "From: $email \r\n";
mail($recipient, $subject, $formcontent, $mailheader) or die("Error!");
echo "Mail Sent. Thank you, we will contact you shortly.";
}
?>

Answer 1

您还可以在提交按钮上添加名称属性。

在你的按钮上添加：

name='submit'

<button name='submit' class="thm-btn bg-clr1" type="submit">Get a Quote</button>

原因是name属性是添加到$_POST数组的内容。出于学习目的，请执行var_dump($_POST);，然后您就会看到结果

Answer 2

根据你上面的评论。

更改

library(dplyr)
library(tidytext)
library(widyr)

df <- data_frame(Id = rep(1:5, each = 2),
                  Text = c("a", "b",
                             "a", "c",
                             "a", "c",
                             "b", "e",
                             "b", "f"))
#define function 
rm_main = function(data)
{
  if(is.data.frame(data)){

    test <- data %>%
      pairwise_count(Text, Id)
  }
  print(data)
  return(list(data))
}

#call function now
rm_main(df)

到

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

试图用PHP发送邮件，错误的代码是什么？
