我有一个使用 jQuery/Ajax/PHP 发送数据的简单表单。PHP 代码在将输入发送到数据库之前验证输入,如果输入无效,则将错误消息返回到响应 div。
它在我的计算机和我自己的服务器上运行良好。但是当我将它上传到客户端的服务器时,它并没有按预期工作。当我从客户端的服务器访问页面时,我注意到以下内容:
仅当所有输入字段都有值时,验证结果才会发送到响应 div。如果任何字段为空,则不会发生任何事情,也不会返回验证消息。
这似乎不是机器问题,因为我使用同一台计算机访问 3 个副本,一个在我的本地主机上,一个在我的服务器上,一个在客户端服务器上。
这是代码;jQuery:
$(document).ready(function() {
$('#signup').click(function() {
var queryString = 'ajax=true';
var txtName = encodeURIComponent($('#txtName').val());
if(txtName.length > 0){
txtName = txtName.replace(/\%/g, '-');
}
var txtEmail = escape($('#txtEmail').val());
var txtPhone = encodeURIComponent($('#txtPhone').val());
if(txtPhone.length > 0){
txtPhone = txtPhone.replace(/\%/g, '-');
}
var txtPhoneCode = encodeURIComponent($('#txtPhoneCode').val());
if(txtPhoneCode.length > 0){
txtPhoneCode = txtPhoneCode.replace(/\%/g, '-');
}
queryString = queryString + '&txtEmail=' + txtEmail;
queryString = queryString + '&txtName=' + txtName;
queryString = queryString + '&txtPhone=' + txtPhone;
queryString = queryString + '&txtPhoneCode=' + txtPhoneCode;
$.ajax({
type: "GET",
url: 'send.php',
data: queryString ,
success: function(msg) {
$('#response').html(msg);
}
});
return false;
});
});
PHP页面:
<?php
if(isset($_GET['ajax']) && ($_GET['ajax'] == 'true')){
$name = trim($_GET['txtName']); // coming from input text
$email = trim($_GET['txtEmail']); // coming from input text
$phone = trim($_GET['txtPhone']); // coming from input text
$phonecode = trim($_GET['txtPhoneCode']); // coming from a select
if(strlen($name) == 0){
echo 'Please enter your name';
}
elseif(strlen($email) == 0){
echo 'Please enter your email';
}
elseif(!preg_match("/^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*$/i", $email)){
echo 'Please enter a valid email';
}
elseif(strlen($phonecode) == 0){
echo 'Please select phone code';
}
elseif(strlen($phone) == 0){
echo 'Please enter your phone';
}
elseif(!preg_match("/^[0-9]*$/i", $phone)){
echo 'Please enter a valid phone';
}
else{
require('config.php');
// send to mysql db
$email = stripslashes($email);
$name = urldecode(str_replace('-', '%', $name));
$phone = urldecode(str_replace('-', '%', $phone));
$phonecode = urldecode(str_replace('-', '%', $phonecode));
$dt = gmdate("Y-m-d H:i:s");
$sql = "insert into subscribers(datecreated, name, email, phone, phonecode) values('$dt', '$name', '$email', '$phone', '$phonecode')";
$result = mysql_query($sql) or die('Error: Failed to save subscription!');
// redirect
echo '<script>setTimeout(function(){ window.location = "thankyou.html#ty"; }, 0);</script>';
}
}
?>
