Question

我创建了一个联系表单，允许上传3个文件。目前，文件大小和文件类型没有限制。我希望能够做到以下几点：

将文件类型限制为“png，gif，jpg，jpeg，bmp”
将文件大小限制为5mb

我目前正在使用PHPMailer通过SMTP发送联系表单。

我的contact_mail.php内容：

<?php
require('phpmailer/class.phpmailer.php');

$mail = new PHPMailer();
$mail->IsSMTP();
$mail->SMTPDebug = 0;
$mail->SMTPAuth = FALSE;
$mail->Port     = 25;  
$mail->Host     = "###HIDDEN###";
$mail->Mailer   = "smtp";
$mail->SetFrom($_POST["userEmail"], $_POST["userName"]);
$mail->AddReplyTo($_POST["userEmail"], $_POST["userName"]);
$mail->AddAddress("###HIDDEN###");  
$mail->Subject = $_POST["subject"];
$mail->WordWrap   = 80;
$mail->Body='Name:  '.$_POST['userName'].'<br />
Telephone:  '.$_POST['telephone'].'<br />
Nationality:  '.$_POST['nationality'].'<br />
Age:  '.$_POST['age'].'<br />
Height:  '.$_POST['height'].'<br/>
Favourites:  '.$_POST['age'].'<br />
Bio:  '.$_POST['content'];

if(is_array($_FILES)) {
$mail->AddAttachment($_FILES['attachmentFile']    ['tmp_name'],$_FILES['attachmentFile']['name']); 
$mail->AddAttachment($_FILES['attachmentFile2']['tmp_name'],$_FILES['attachmentFile2']['name']); 
$mail->AddAttachment($_FILES['attachmentFile3']['tmp_name'],$_FILES['attachmentFile3']['name']); 
}

$mail->IsHTML(true);

if(!$mail->Send()) {
echo "<p class='error'>Problem in Sending Mail.</p>";
} else {
echo "<p class='success'>Contact Mail Sent.</p>";
}   
?>

表格内容：

<div class="col-xs-12 col-sm-4 labelPanel">
<label>Portfolio Images</label><br/>
<input type="file" name="attachmentFile" id="attachmentFile" class="inputField">
<input type="file" name="attachmentFile2" id="attachmentFile" class="inputField">
<input type="file" name="attachmentFile3" id="attachmentFile" class="inputField">
</div>

PHP代码＆amp;验证：

<script type="text/javascript">
$(document).ready(function (e){
$("#frmContact").on('submit',(function(e){
e.preventDefault();
$('#loader-icon').show();
var valid;  
valid = validateContact();
if(valid) {
    $.ajax({
    url: "contact_mail.php",
    type: "POST",
    data:  new FormData(this),
    contentType: false,
    cache: false,
    processData:false,
    success: function(data){
    $("#mail-status").html(data);
    $('#loader-icon').hide();
    },
    error: function(){}             

    });
}
}));

function validateContact() {
var valid = true;   
$(".inputField").css('background-color','');
$(".info").html('');

if(!$("#userName").val()) {
    $("#userName-info").html("(required)");
    $("#userName").css('background-color','#FFFFDF');
    valid = false;
}
if(!$("#telephone").val()) {
    $("#telephone-info").html("(required)");
    $("#telephone").css('background-color','#FFFFDF');
    valid = false;
}
if(!$("#nationality").val()) {
    $("#nationality-info").html("(required)");
    $("#nationality").css('background-color','#FFFFDF');
    valid = false;
}
if(!$("#age").val()) {
    $("#age-info").html("(required)");
    $("#age").css('background-color','#FFFFDF');
    valid = false;
}
if(!$("#height").val()) {
    $("#height-info").html("(required)");
    $("#height").css('background-color','#FFFFDF');
    valid = false;
}
if(!$("#favourites").val()) {
    $("#favourites-info").html("(required)");
    $("#favourites").css('background-color','#FFFFDF');
    valid = false;
}
if(!$("#userEmail").val()) {
    $("#userEmail-info").html("(required)");
    $("#userEmail").css('background-color','#FFFFDF');
    valid = false;
}
if(!$("#userEmail").val().match(/^([\w-\.]+@([\w-]+\.)+[\w-]{2,4})?$/)) {
    $("#userEmail-info").html("(invalid)");
    $("#userEmail").css('background-color','#FFFFDF');
    valid = false;
}
if(!$("#subject").val()) {
    $("#subject-info").html("(required)");
    $("#subject").css('background-color','#FFFFDF');
    valid = false;
}
if(!$("#content").val()) {
    $("#content-info").html("(required)");
    $("#content").css('background-color','#FFFFDF');
    valid = false;
}

return valid;
}

});
</script>

我对PHP很陌生，所以我按照在线教程创建了联系表单 - 不幸的是，在图片上传验证时，我有点卡住了。
