嗨，我有两个 HTML 表单，当第一个表单提交时，JavaScript 函数提交第二个表单，其中一个表单有效，但第二个表单不起作用，我不确定是表单还是帖子页面可以提供帮助。
第一个表单发送一封电子邮件，这是正确发送电子邮件，将正确的数据发送到正确的电子邮件地址。
第二种形式是上传一个文件，它似乎根本没有做任何事情，现在屏幕上显示错误我已经做了 try catch ，但没有显示任何内容我也查看了日志，但什么也没有显示我是
HTML
<div id="loginborder">
<form id ="upload" enctype="multipart/form-data" action="upload_logo.php" method="POST">
<input name="userfile" type="file" />
<input type="submit" onsubmit="alert()" value="dont press" disabled>
</form>
<div id="login">
<form method="post" action="<?php echo $_SERVER["PHP_SELF"];?>">
<input type="hidden" name="subject" value="Can you create me a Contributors account">
<input type="text" name="first_name" id="first_name" placeholder="Name">
<input type="text" name="company" id="company" placeholder="Company Name">
<input type="checkbox" id="tc" onclick= "checkbox()">
<input type="submit" id="submit" onsubmit="alert()" name="submit" value="Register" disabled>
</form>
</div>
</div>
<?php
}
else
// the user has submitted the form
{
// Check if the "subject" input field is filled out
if (isset($_POST["subject"]))
{
sleep(5);
$subject = $_POST["subject"];
$first = $_POST["first_name"];
$company = $_POST["company"];
$therest = "First name= $first" . "\r\n" . "Company= $company" . "\r\n";
}
echo "$therest <br>";
$first = wordwrap($first, 70);
mail("careersintheclassroom01@gmail.com",$subject,$name,$therest,"subject: $subject\n");
echo "Thank you for sending us feedback";
header( "refresh:5;url=index.php" );
}
?>
</body>
</html>
JavaScript
<script type="text/javascript">
function alert()
{
document.getElementById("upload").submit();
}
function checkbox(){
if (document.getElementById("tc").checked == true)
document.getElementById("submit").disabled = false;
else
document.getElementById("submit").disabled = true;
}
$('input[placeholder],input[placeholder],input[placeholder],input[placeholder],input[placeholder]').placeholder();
</script>
Upload_Logo.php
<html>
<head>
</head>
</html>
<?php
$uploaddir = "./images/";
echo $uploaddir;
mkdir($uploaddir, true);
$uploadfile = $uploaddir . basename($_FILES['userfile']['name']);
echo "<br />";
echo " <b>Your media has been uploaded</b><br /><br /> ";
?>
<?php echo $_SERVER["PHP_SELF"];?>在第二种形式上，调用页面底部的 php，这是正在工作的，它是 upload_logo.php，目前尚未工作，任何帮助将不胜感激
最佳答案
您正尝试一次提交 2 个表单。这是行不通的，因为您的浏览器一次只能定向到 1 个页面，因此您使用 JavaScript 提交上传表单的尝试会被提交的联系表单取消。我建议您将文件输入移动到与联系人字段相同的表单中，并在“用户已提交表单”部分中处理它们。
像这样的事情应该可以解决问题:
<?php
if (!isset($_POST["submit"]))
{
?>
<div id="loginborder">
<div id="login">
<form enctype="multipart/form-data" method="POST">
<input name="userfile" type="file" />
<input type="hidden" name="subject" value="Can you create me a Contributors account">
<input type="text" name="first_name" id="first_name" placeholder="Name">
<input type="text" name="company" id="company" placeholder="Company Name">
<input type="checkbox" id="tc" onclick="checkbox()">
<input type="submit" id="submit" name="submit" value="Register" disabled>
</form>
</div>
</div>
<?php
}
else
// the user has submitted the form
{
// Check if the "subject" input field is filled out
if (!empty($_POST["subject"]))
{
sleep(5);
$subject = $_POST["subject"];
$first = $_POST["first_name"];
$company = $_POST["company"];
$therest = "First name= $first" . "\r\n" . "Company= $company" . "\r\n";
echo "$therest <br>";
$first = wordwrap($first, 70);
mail("careersintheclassroom01@gmail.com",$subject,$name,$therest,"subject: $subject\n");
echo "Thank you for sending us feedback";
header( "refresh:5;url=index.php" );
}
if (isset($_FILES['userfile']['name'])) {
$uploaddir = "./images/";
if (!file_exists($uploaddir)) {
mkdir($uploaddir, true);
}
$uploadfile = $uploaddir . basename($_FILES['userfile']['name']);
move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile);
echo "<br />";
echo " <b>Your media has been uploaded</b><br /><br /> ";
}
}
?>
</body>
