我在通过jQuery validate plugin上传图片时遇到了麻烦。我认为它不会将文件发送到我的PHP脚本，因为它没有通过此检查：
if ($_FILES['profielfoto']['size'] > 1) {
现在我对AJAX和这个插件知之甚少，所以我的问题是，如果有人可以查看我的代码并且可能发现错误或其他什么。
使用Javascript：
$(document).ready(function(){
$("#registreer-formulier").validate({
rules: {
email: {
required: true,
email: true
},
voornaam: {
required: true,
minlength: 3
},
achternaam: {
required: true,
minlength: 3
},
telefoon: {
required: true,
number: true
},
profielfoto: {
required: true,
extension: 'jpg|jpeg|png'
}
},
messages: {
email: 'U moet een email opgeven',
voornaam: 'U moet een voornaam opgeven.',
achternaam: 'U moet een achternaam opgeven.',
telefoon: 'U moet een telefoonnumer opgeven.',
profielfoto: 'U moet een profielfoto uploaden.',
},
submitHandler: submitForm
});
function submitForm() {
var data = $('#registreer-formulier').serialize();
$.ajax ({
type: 'POST',
url: 'assets/php/registreren.php',
data: data,
beforeSend: function() {
$('#error').fadeOut();
$('#btn-submit').html('Bezig met versturen...');
},
success: function (data) {
if (data == '1') {
$('#errordiv').fadeIn(1000, function() {
$('#errordiv').html('<p>Email adres is al in gebruik</p>');
$('#btn-submit').html('Registreren');
});
} else if (data == 'geregistreerd'){
$('#errordiv').fadeIn(1000, function() {
$('#errordiv').html('<p> registreren is gelukt!</p>');
$('#btn-submit').hide();
})
}
}
});
return false;
}
});
PHP：
<?php
require_once 'config.php';
if ($_POST) {
$email = trim($_POST['email']);
$voornaam = trim($_POST['voornaam']);
$achternaam = trim($_POST['achternaam']);
$telefoon = trim($_POST['telefoon']);
$profielfoto = trim($_POST['profielfoto']);
$allergie1 = trim($_POST['allergie1']);
$allergie2 = trim($_POST['allergie2']);
$allergie3 = trim($_POST['allergie3']);
$allergie4 = trim($_POST['allergie4']);
$objCheck = $objDatabaseRegistreren->prepare('SELECT email FROM leden WHERE email = :email');
$objCheck->bindParam(':email', $email);
$objCheck->execute();
$count = $objCheck->rowCount();
if ($count == 0) {
if ($_FILES['profielfoto']['size'] > 1) {
$imgName = $_FILES['profielfoto']['name'];
$imgTmpName = $_FILES['profielfoto']['tmp_name'];
$imgExtension = explode($imgName, '.');
$imgExtension = end($imgName);
$random = rand(1, 10000);
$imgNewName = $random . '_' . $voornaam . '_' . $achternaam . '.' . $imgExtension;
$leden->registreren($email, $voornaam, $achternaam, $telefoon, $imgNewName, $allergie1, $allergie2, $allergie3, $allergie4);
move_uploaded_file($imgTmpName, '../images/profielfotos/' . $imgNewName);
echo 'geregistreerd';
}
} else {
echo '1';
}
}
?>

答案 0 :(得分：1)
尝试FormData
data: new FormData($('#registreer-formulier')[0]),
processData: false
而不是
data = $('#registreer-formulier').serialize();
