几封联系方式的电子邮件

Question

我正在尝试创建一个联系表单，可以根据用户选择的操作将邮件发送到不同的电子邮件。

这是我的代码：

    <?php
if($_POST)
{  

   if(isset($_POST['ort1'])) { 
    $to="a@mail.com";   
    }
  else {
    $to="b@mail.com";       
    }   



    //check if its an ajax request, exit if not
    if(!isset($_SERVER['HTTP_X_REQUESTED_WITH']) AND strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) != 'xmlhttprequest') {

        $output = json_encode(array( //create JSON data
            'type'=>'error', 
            'text' => 'Sorry Request must be Ajax POST'
        ));
        die($output); //exit script outputting json data
    } 

    //Sanitize input data using PHP filter_var().
    $r_name      = filter_var($_POST["r_name"], FILTER_SANITIZE_STRING);
    $r_email     = filter_var($_POST["r_email"], FILTER_SANITIZE_EMAIL);
    $ort1      = filter_var($_POST["ort1"], FILTER_SANITIZE_STRING);
    $ort2      = filter_var($_POST["ort2"], FILTER_SANITIZE_STRING);

    //additional php validation
    if(strlen($r_name)<4){ // If length is less than 4 it will output JSON error.
        $output = json_encode(array('type'=>'error', 'text' => 'Name is too short or empty!'));
        die($output);
    }
    if(!filter_var($r_email, FILTER_VALIDATE_EMAIL)){ //email validation
        $output = json_encode(array('type'=>'error', 'text' => 'Please enter a valid email!'));
        die($output);
    }

    //email body
    $message_body = $r_name."\r\nEmail : ".$r_email;

    //proceed with PHP email.
    $subject = 'From: The president' .
    $headers = 'From: '.$r_name.'' . "\r\n" .
    'Reply-To: '.$r_email.'' . "\r\n" .
    'X-Mailer: PHP/' . phpversion();


    $send_mail = mail($to, $subject, $headers, $message_body);  

    if(!$send_mail)
    {
        //If mail couldn't be sent output error. Check your PHP email configuration (if it ever happens)
        $output = json_encode(array('type'=>'error', 'text' => 'Could not send mail! Please check your PHP mail configuration.'));
        die($output);
    }else{
        $output = json_encode(array('type'=>'message', 'text' => 'Hi '.$r_name .' Thank you for your email'));
        die($output);
    }
}
?>

Html：

<div class="form-style" id="contact_form">
<div class="form-style-heading">Please Contact Us</div>
<div id="contact_results"></div>
<div id="contact_body">
    <label><span>Name <span class="required">*</span></span>
        <input type="text" name="name" id="name" required="true" class="input-field"/>
    </label>
    <label><span>Email <span class="required">*</span></span>
        <input type="email" name="email" required="true" class="input-field"/>
    </label>
    <label>
    <span>Norr</span><input type="checkbox" name="ort1">
    <span>Söder</span><input type="checkbox" name="ort2">
    </label>
    <label>
        <span>&nbsp;</span><input type="submit" id="submit_btn" value="Submit" />
    </label>
</div>

jQuery的：

$(document).ready(function() {
$("#submit_btn").click(function() { 

    var proceed = true;
    //simple validation at client's end
    //loop through each field and we simply change border color to red for invalid fields       
    $("#contact_form input[required=true], #contact_form textarea[required=true]").each(function(){
        $(this).css('border-color',''); 
        if(!$.trim($(this).val())){ //if this field is empty 
            $(this).css('border-color','red'); //change border color to red   
            proceed = false; //set do not proceed flag
        }
        //check invalid email
        var email_reg = /^([\w-\.]+@([\w-]+\.)+[\w-]{2,4})?$/; 
        if($(this).attr("type")=="email" && !email_reg.test($.trim($(this).val()))){
            $(this).css('border-color','red'); //change border color to red   
            proceed = false; //set do not proceed flag              
        }   
    });

    if(proceed) //everything looks good! proceed...
    {
        //get input field values data to be sent to server
        post_data = {
            'r_name'     : $('input[name=name]').val(), 
            'r_email'    : $('input[name=email]').val(), 
            'ort1'       : $('input[name=ort1]').val(),
            'ort2'       : $('input[name=ort2]').val()

        };

        //Ajax post data to server
        $.post('process.php', post_data, function(response){  
            if(response.type == 'error'){ //load json data from server and output message     
                output = '<div class="error">'+response.text+'</div>';
            }else{
                output = '<div class="success">'+response.text+'</div>';
                //reset values in all input fields
                $("#contact_form  input[required=true], #contact_form textarea[required=true]").val(''); 
                $("#contact_form #contact_body").slideUp(); //hide form after success
            }
            $("#contact_form #contact_results").hide().html(output).slideDown();
        }, 'json');
    }
});

//reset previously set border colors and hide all message on .keyup()
$("#contact_form  input[required=true], #contact_form textarea[required=true]").keyup(function() { 
    $(this).css('border-color',''); 
    $("#result").slideUp();
});

}）;

正如你所看到我在开始时做了一个if循环但不幸的是它总是发送到a@mail.com。我一直试图找到另一种解决方案，但我无法理解为什么这个解决方案不起作用。
