我有聯繫表單，它使用Javascript和PHP。Javascript沒有將變量傳遞給PHP與HTML表格
我的問題是，JavaScript沒有將其變量傳遞給PHP腳本。我發現了以下內容：
變量確實在javascript中設置，因爲它通過javascript內部的變量檢查並使用顯示變量的警報。
隨着它到達PHP腳本，變量不再存在。我試圖在PHP腳本中註釋掉這個檢查，然後它成功地發送一封郵件，但除了PHP腳本中的靜態內容之外，郵件是空的。
我已經嘗試過各種不同的方法，包括直接從http.send（）函數傳遞變量。
下面是相關的代碼（這些都是在Web服務器上的所有3個不同的文件）：
HTML：
div class="contact_form">
<h4>Get in touch</h4>
<form method="post">
<input type="text" name="Name" id="name" value="Name" onfocus="this.value = this.value=='Name'?'':this.value;" onblur="this.value = this.value==''?'Name':this.value;" />
<input type="text" name="Email" id="email" value="Email" onfocus="this.value = this.value=='Email'?'':this.value;" onblur="this.value = this.value==''?'Email':this.value;" />
<input type="text" value="Subject (Hosting, Requests, Appeal, Report, etc.)" id="subject" onfocus="this.value = this.value=='Subject (Hosting, Requests, Appeal, Report, etc.)'?'':this.value;" onblur="this.value = this.value==''?'Subject (Hosting, Requests, Appeal, Report, etc.)':this.value;" />
<textarea name="Message" id="body" onfocus="this.value = this.value=='Message'?'':this.value;" onblur="this.value = this.value==''?'Message':this.value;">Message</textarea>
<input type="submit" name="submit" id="submit" value="send" class="submit-button" onClick="return check_values();" />
</form>
<div id="confirmation" style="display:none; position: relative; z-index: 600; font-family: 'Open Sans', sans-serif; font-weight: 300; font-size: 16px; color: #4e4e4e;"></div>
</div> <!-- end .contact_form -->
的Javascript：
var http = createRequestObject();
var areal = Math.random() + "";
var real = areal.substring(2,6);
function createRequestObject() {
var xmlhttp;
try { xmlhttp=new ActiveXObject("Msxml2.XMLHTTP"); }
catch(e) {
try { xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");}
catch(f) { xmlhttp=null; }
}
if(!xmlhttp&&typeof XMLHttpRequest!="undefined") {
xmlhttp=new XMLHttpRequest();
}
return xmlhttp;
}
function sendRequest() {
var rnd = Math.random();
var name = escape(document.getElementById("name").value);
var email = escape(document.getElementById("email").value);
var subject = escape(document.getElementById("subject").value);
var body = escape(document.getElementById("body").value);
try{
http.open('POST','pform.php');
http.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
http.send('name='+name+'&email='+email+'&subject='+subject+'&body='+body+'&rnd='+rnd);
http.onreadystatechange = handleResponse;
}
catch(e){}
finally{}
}
function check_values() {
var valid = '';
var name = document.getElementById("name").value;
var email = document.getElementById("email").value;
var subject = document.getElementById("subject").value;
var body = document.getElementById("body").value;
if(trim(name) == "" ||
trim(email) == "" ||
trim(subject) == "" ||
trim(body) == "") {
alert("Please complete all fields");
} else {
if(isEmail(email)) {
document.getElementById("submit").disabled=true;
document.getElementById("submit").value='Please Wait..';
sendRequest();
} else {
alert("Email appears to be invalid\nPlease check and try again");
document.getElementById("email").focus();
document.getElementById("email").select();
}
}
}
function handleResponse() {
try{
if((http.readyState == 4)&&(http.status == 200)){
var response = http.responseText;
document.getElementById("confirmation").innerHTML = response;
document.getElementById("confirmation").style.display ="";
}
}
catch(e){}
finally{}
}
function isUndefined(a) {
return typeof a == 'undefined';
}
function trim(a) {
return a.replace(/^s*(S*(s+S+)*)s*$/, "$1");
}
function isEmail(a) {
return (a.indexOf(".") > 0) && (a.indexOf("@") > 0);
}
PHP：
<?php
error_reporting(0);
$page_title = "Contact Us Form";
$email_it_to = "[email protected]";
$error_message = "Please complete the form first";
$confirmation = "Thank you, your message has been successfully sent.";
if(!isset($rnd) || !isset($name) || !isset($email) || !isset($subject) || !isset($body)) {
echo $error_message;
die();
}
$email_from = $email;
$email_subject = "Contact Form: ".stripslashes($subject);
$email_message = "Please find below a message submitted by '".stripslashes($name);
$email_message .="' on ".date("d/m/Y")." at ".date("H:i")."\n\n";
$email_message .= stripslashes($body);
$headers = 'From: '.$email_from."\r\n" .
'Reply-To: '.$email_from."\r\n" .
'X-Mailer: PHP/' . phpversion();
mail($email_it_to, $email_subject, $email_message, $headers);
echo "<b>$confirmation</b>";
die();
?>
在PHP腳本中，當您的AJAX調用爲POSTING數據時，您必須從'$ _POST'檢索數據。在你的PHP中，你直接使用你的變量。誰已經初始化他們。？ – MatRt
