所以我需要创建一个电子邮件表单，我的文件名目前是test12.php，即使我没有按下提交按钮，也会执行将表单通过电子邮件发送到我的收件箱的脚本！这是我的代码：
<?php
if(isset($_POST['email'])) {
// EDIT THE 2 LINES BELOW AS REQUIRED
$email_to = "you@yourdomain.com";
$email_subject = "Your email subject line";
function died($error) {
// your error code can go here
echo "We are very sorry, but there were error(s) found with the form you submitted. ";
echo "These errors appear below.<br /><br />";
echo $error."<br /><br />";
echo "Please go back and fix these errors.<br /><br />";
die();
}
// validation expected data exists
if(!isset($_POST['first_name']) ||
!isset($_POST['last_name']) ||
!isset($_POST['email']) ||
!isset($_POST['telephone']) ||
!isset($_POST['comments'])) {
died('We are sorry, but there appears to be a problem with the form you submitted.');
}
$first_name = $_POST['first_name']; // required
$last_name = $_POST['last_name']; // required
$email_from = $_POST['email']; // required
$telephone = $_POST['telephone']; // not required
$comments = $_POST['comments']; // required
$error_message = "";
$email_exp = '/^[A-Za-z0-9._%-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/';
if(!preg_match($email_exp,$email_from)) {
$error_message .= 'The Email Address you entered does not appear to be valid.<br />';
}
$string_exp = "/^[A-Za-z .'-]+$/";
if(!preg_match($string_exp,$first_name)) {
$error_message .= 'The First Name you entered does not appear to be valid.<br />';
}
if(!preg_match($string_exp,$last_name)) {
$error_message .= 'The Last Name you entered does not appear to be valid.<br />';
}
if(strlen($comments) < 2) {
$error_message .= 'The Comments you entered do not appear to be valid.<br />';
}
if(strlen($error_message) > 0) {
died($error_message);
}
$email_message = "Form details below.\n\n";
function clean_string($string) {
$bad = array("content-type","bcc:","to:","cc:","href");
return str_replace($bad,"",$string);
}
$email_message .= "First Name: ".clean_string($first_name)."\n";
$email_message .= "Last Name: ".clean_string($last_name)."\n";
$email_message .= "Email: ".clean_string($email_from)."\n";
$email_message .= "Telephone: ".clean_string($telephone)."\n";
$email_message .= "Comments: ".clean_string($comments)."\n";
// create email headers
$headers = 'From: '.$email_from."\r\n".
'Reply-To: '.$email_from."\r\n" .
'X-Mailer: PHP/' . phpversion();
@mail($email_to, $email_subject, $email_message, $headers);
if (!isset($_POST['Submit'])) {
}
?>
<form name="contactform" method="post" action="test12.php" target="success" id="CmForm">
<tr>
<td valign="top">
<input class="text-area w-input" type="text" name="first_name" maxlength="50" size="30" placeholder="Enter your first name" required="required">
</td>
</tr>
<tr>
<td valign="top">
<input class="text-area w-input" type="text" name="last_name" maxlength="50" size="30" placeholder="Enter your last name" required="required">
</td>
</tr>
<tr>
<td valign="top">
<input class="text-area w-input" type="text" name="email" maxlength="80" size="30" placeholder="Enter your email adress" required="required">
</td>
</tr>
<tr>
<td valign="top">
<input class="text-area w-input" type="text" name="telephone" maxlength="30" size="30" placeholder="Enter your subject" required="required">
</td>
</tr>
<tr>
<td valign="top">
<textarea class="text-area w-input" name="comments" maxlength="5000" cols="25" rows="6" placeholder="Write message" required="required"></textarea>
</td>
</tr>
<tr>
<input class="submit-button w-button" data-wait="Please wait..." type="submit" value="Submit" onclick='$("#success").show()' onclick='$("#CmForm").hide()'>
</td>
</tr>
</form>
<?php
}
else {
// form engine
echo "<div>Thank you! Your submission has been received!</div>";
}
?>
此外，我希望它在我点击提交后显示谢谢消息，并使表单本身消失！而且我怎么能让文本框变小？他们目前是巨大的！
答案 0 :(得分：0)
您的提交按钮未正确命名，因此检查失败。更像这样：
<input class="submit-button w-button" data-wait="Please wait..." type="submit" name="Submit" value="Submit" onclick='$("#success").show()' onclick='$("#CmForm").hide()'>
您也可能希望以表格提交代码在此情况的else情况下的方式移动检查if (!isset($_POST['Submit'])) {，否则您将始终收到“死亡”错误消息。
使用css设置textareas的宽度。
<style>
.text-area{width: 300px;}
</style>
重组的代码如下所示;但是在处理导致“死亡（）”的错误时仍有改进的余地;功能。
if (!isset($_POST['Submit'])) {
?>
<form name="contactform" method="post" action="test12.php" target="success" id="CmForm">
<tr>
<td valign="top">
<input class="text-area w-input" type="text" name="first_name" maxlength="50" size="30" placeholder="Enter your first name" required="required">
</td>
</tr>
<tr>
<td valign="top">
<input class="text-area w-input" type="text" name="last_name" maxlength="50" size="30" placeholder="Enter your last name" required="required">
</td>
</tr>
<tr>
<td valign="top">
<input class="text-area w-input" type="text" name="email" maxlength="80" size="30" placeholder="Enter your email adress" required="required">
</td>
</tr>
<tr>
<td valign="top">
<input class="text-area w-input" type="text" name="telephone" maxlength="30" size="30" placeholder="Enter your subject" required="required">
</td>
</tr>
<tr>
<td valign="top">
<textarea class="text-area w-input" name="comments" maxlength="5000" cols="25" rows="6" placeholder="Write message" required="required"></textarea>
</td>
</tr>
<tr>
<input class="submit-button w-button" data-wait="Please wait..." type="submit" name="Submit" value="Submit" onclick='$("#success").show()' onclick='$("#CmForm").hide()'>
</td>
</tr>
</form>
<?php
} else {
// EDIT THE 2 LINES BELOW AS REQUIRED
$email_to = "you@yourdomain.com";
$email_subject = "Your email subject line";

对代码的进一步改进是：不要在“死亡”中死亡，而是使用提交中的预填充字段显示表单。
