使用jquery / ajax / php提交表单，无需刷新页面。 无法获得电子邮件的表单价值

问题描述：

I'm looking to submit a single form input for a tracking number using jquery/php so that the page doesn't refresh. I am able to submit the form and have the email sent to me but can't figure out what to put in $email_body so it actually emails me the form info. The email will send blank (So I assume email is in the PHP code). Please see below for HTML/JS/PHP:

HTML:

    <form id="track-form" accept-charset="UTF-8" action="" size="30" class="form-inline" method="POST">
      <input class="focus" name="tracking" id="tracking" placeholder="tracking code" value="" type="text"/>
      <input class="btn btn-default btn-track" name="submit" type="submit" value="Send" />  
      <img id="success" style="display:none" src="img/check.png" />
      <br>    
      <label class="error" for="tracking" id="track-error">You must enter your tracking code!</label>  
    </form>

JS:

$(document).ready(function() { 
  $('.error').hide(); 
  $("#track-form").on('submit', function(e) {  


$('.error').hide();
  var track = $("input#tracking").val();
    if (track == "") {
        $("label#track-error").show();
        $("input#tracking").focus();
        return false;
    };   

$.ajax({
  url:'sendtrack.php',
  data:$(this).serialize(),
  type:'POST',
  success:function(data){
    console.log(data);
    $("#success").fadeIn(300); //=== Show Success Message== 
   },
});

e.preventDefault(); 

 });
});

PHP (WHERE THE PROBLEM IS):

<?php

$track = $_POST['tracking'];

$email_from = 'info@website.com';
$email_subject = "New Tracking Info";
$email_body = "Tracking Number: $track".


$to = "email@gmail.com";
$headers = "From: $email_from 
";

//Send the email!
mail($to,$email_subject,$email_body,$headers);

?>

If I leave $email_body as is I get a "500 Server Error". If I leave it blank I get an email with just "email@gmail.com" in it, no tracking number.

Thanks in advance for your help!

我希望使用jquery / php为跟踪号提交单个表单输入，以便页面不会 刷新。 我能够提交表单并将电子邮件发送给我，但无法弄清楚要放在$ email_body中的内容，所以它实际上会通过电子邮件向我发送表单信息。 电子邮件将发送空白（因此我假设电子邮件在PHP代码中）。 请参阅下面的HTML / JS / PHP： p>

HTML： p> 

 ＆lt; form id =“track-form”accept-charset  =“UTF-8”action =“”size =“30”class =“form-inline”method =“POST”＆gt; 
＆lt; input class =“focus”name =“tracking”id =“tracking”占位符 =“跟踪代码”value =“”type =“text”/＆gt; 
＆lt;输入类=“btn btn-default btn-track”name =“submit”type =“submit”value =“发送”/＆gt  ;  
＆lt; img id =“success”style =“display：none”src =“img / check.png”/＆gt; 
＆lt; br＆gt;  
＆lt; label class =“error”for =“tracking”id =“track-error”＆gt;您必须输入跟踪代码！＆lt; / label＆gt;  
＆lt; / form＆gt; 
  code>  pre> 
 
 
 JS： p> 
 
 


  $（document）.ready（function（）  {
 $（'。error'）。hide（）; 
 $（“＃track-form”）。on（'submit'，function（e）{
 
 
 $（'。error'  ）.hide（）; 
 var track = $（“input＃tracking”）。val（）; 
 if（track ==“”）{
 $（“label＃track-error”）。show（  ）; 
 $（“input＃tracking”）。focus（）; 
 return false; 
}; 
 
 $ .ajax（{
 url：'sendtrack.php'，
 data：$  （this）.serialize（），
 type：'POST'，
 success：function（data）{
 console.log（data）; 
 $（“＃success”）。fadeIn（300）; /  / ===显示成功消息== 
}，
}）; 
 
e.preventDefault（）; 
 
}}; 
}）; 
  code>  pre> \  n 
 
 PHP（问题出在哪里）： p> 
 
 


 ＆lt;？php 
 
 $ track = $ _POST ['tracking']; 
 \  n $ email_from ='info@website.com'; 
 $ email_subject =“新跟踪信息”; 
 $ email_body =“跟踪号码：$ track”。
 
 
 $ n =“email @ gmail。  com“; 
 $ headers =”From：$ email_from 
 
“; 
 
 //发送电子邮件！
mail（$ to，$ email_subject，$ email_body，$ headers）; 
 
？  ＆GT; 
 代码>  PRE>  
 
 
如果我保留$ email_body，我会收到“500 Server Error”。 如果我留空，我会收到一封电子邮件，其中只有“email@gmail.com”，没有跟踪号。 p> 
 
 


提前感谢您的帮助！ p>

Change this line:

$email_body = "Tracking Number: $track".

to:

$email_body = "Tracking Number: $track";

The closing semi-colon was missing. You had a dot in its place.

You can also try:

$email_body = "Tracking Number: " . $track . "
";

NOTE: Using/adding headers as below, will reduce the chance of being mistaken for SPAM.

For example:

$headers = 'From: webmaster@example.com' . "
" .
'Reply-To: webmaster@example.com' . "
" .
'X-Mailer: PHP/' . phpversion();

Therefore your new headers would read as:

$headers = 'From: $email_from' . "
" .
'Reply-To: webmaster@example.com' . "
" .
'X-Mailer: PHP/' . phpversion();

As per the mail() function on PHP.net http://php.net/manual/en/function.mail.php

your don't have a semicolon in the end

$email_body = "Tracking Number: $track".
