提交按钮在表单和 PHP 中不起作用

Submit button not working within form and PHP

本文关键字：PHP 不起作用 表单 按钮 提交      更新时间：2023-09-26

我对提交按钮有问题：它只是不起作用。它似乎适用于我以前的表格。我也在使用Spry验证。这是一个带有PHP的简单HTML。我看不出我的错误在哪里（我刚刚开始学习PHP）。我已经在论坛和互联网上查看了一下，但我找不到问题的答案。我正在尝试通过电子邮件将基本表单发送给我，其中包含在同一表单中上传文件的选项。问题来自表单格式还是 PHP 文件？以下是我的代码：这是位于<body><div id="content">...</div></body>中的 HTML 表单 

<p><form action="upload.php" name="form1" id="form1" method="post"    enctype="multipart/form-data">

这是外部PHP（上传.php）文件，其括号类型与以前的HTML（相同的CSS和HTML正文）相同：

<?php
$allowedExts = array("pdf", "doc");
$temp = explode(".", $_FILES["file"]["name"]);
$extension = end($temp);
if ((($_FILES["file"]["type"] == "application/pdf")
|| ($_FILES["file"]["type"] == "aaplication/doc"))
&& ($_FILES["file"]["size"] < 20000)
&& in_array($extension, $allowedExts))
  {
  if ($_FILES["file"]["error"] > 0)
    {
    echo "Return Code: " . $_FILES["file"]["error"] . "<br>";
    }
  else
    {
    echo "Upload: " . $_FILES["file"]["name"] . "<br>";
    echo "Type: " . $_FILES["file"]["type"] . "<br>";
    echo "Size: " . ($_FILES["file"]["size"] / 1024) . " kB<br>";
    echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br>";
    if (file_exists("upload/" . $_FILES["file"]["name"]))
      {
      echo $_FILES["file"]["name"] . " already exists. ";
      }
    else
      {
      move_uploaded_file($_FILES["file"]["tmp_name"],
      "upload/" . $_FILES["file"]["name"]);
      echo "Stored in: " . "upload/" . $_FILES["file"]["name"];
      }
    }
  }
else
  {
  echo "Invalid file";
  }

$firstname=$_POST['firstname'];
$lastname=$_POST['lastname'];
$title=$_POST['title'];
$address=$_POST['address'];
$postal=$_POST['postal'];
$city=$_POST['city'];
$phone=$_POST['phone'];
$email=$_POST['email'];
$comments=$_POST['comments'];
$province=$_POST['province'];

$date=gmdate("M d Y");

print"<p><b>$date</b></p>";
print"<p>Thank you $firstname $lastname! We will get back to you.</p>";

$to="someuser@gmail.com";
$subject="Candidate Resume";
$body="Date:$date 'n Subject:$subject 'n First Name:$firstname 'n Last Name:$lastname 'n Title:$title 'n Address:$address 'n City:$city 'n Province:$province 'n Postal Code:$postal 'n Telephone:$phone 'n Email:$email 'n Additional Information:$comments 'n'n";
mail($to,$subject,$body);
?>

您的脚本可以工作，只需将 if 语句中的文件大小值增加到可容纳这些类型的文件的值即可。（$_FILES["文件"]["大小"] <500000）

你只允许 19k。

检查服务器上的PHP错误日志，看看是否可以获得有关其失败原因的一些信息。在调试一些不起作用的代码时，这多次帮助了我。
