Php Ajax验证码检查
基本上,我在index.php中有一段ajax代码,它可以工作:Php Ajax验证码检查,php,jquery,ajax,Php,Jquery,Ajax,基本上,我在index.php中有一段ajax代码,它可以工作: $(function() { $("#submitbtn").click(function() { var txt_from = $("#txt_from").val(); var txt_body = $("#txt_body").val(); var captcha_code = $("#captcha_code").val(); var txt_number = $("#txt_numb
$(function() {
$("#submitbtn").click(function() {
var txt_from = $("#txt_from").val();
var txt_body = $("#txt_body").val();
var captcha_code = $("#captcha_code").val();
var txt_number = $("#txt_number").val();
var dataString = 'txt_from=' + txt_from + '&txt_body=' + txt_body + '&captcha_code=' + captcha_code + '&txt_number=' + txt_number;
if (txt_body == '' || txt_number == '' || txt_from == '' || captcha_code == '') {
$('.alertsuccess').fadeOut(200).hide();
$('.alerterror').fadeIn(200).show();
//$('.alert-box').fadeIn(200).show();
} else {
$.ajax({
type: "POST",
url: "sendsms.php",
data: dataString,
success: function() {
$('.alertsuccess').fadeOut(200).hide();
$('.alertsuccess').fadeIn(200).show();
$('.alerterror').fadeOut(200).hide();
document.getElementById('captcha').src = 'securimage/securimage_show.php?' + Math.random();
$('#txt_from').val('');
$('#txt_body').val('');
$('#txt_number').val('');
$('#captcha_code').val('');
}
});
}
return false;
});
});
在我的sendsms.php中
<?php
session_start();
if ($_POST) {
include_once 'securimage/securimage.php';
// header('Location: maintenance.php');
$securimage = new Securimage();
include "smsGateway.php";
include "filter.php";
$smsGateway = new SmsGateway('email@gmail.com', 'pword');
if ($securimage->check($_POST['captcha_code']) == false) {
echo "<script>alert('The security code entered was incorrect. Please go back and try again.');window.location.href='javascript:history.go(-1)';</script>";
exit;
}
$numto = sanitize($_POST['txt_number']);
$num = "+63" . $numto;
$deviceID = 1254;
$number = $num;
$from = $_POST['txt_from'];
$message = $from . ":\n" . sanitize($_POST['txt_body']);
$result = $smsGateway->sendMessageToNumber($number, $message, $deviceID)
}
?>
HTML表单中的
将页面URL或页面名称嵌入到隐藏的输入中
<input type="hidden" name="back" value="index.html" />
PHP
您可以通过在php文件上创建json编码的响应来实现
echo json_encode(数组('status'=>'failed','message'=>'输入的安全代码不正确。请返回并重试')代码>
然后,在ajax成功的情况下,检查它是否返回了成功状态
您的脚本
$(function() {
$("#submitbtn").click(function() {
var txt_from = $("#txt_from").val();
var txt_body = $("#txt_body").val();
var captcha_code = $("#captcha_code").val();
var txt_number = $("#txt_number").val();
var dataString = 'txt_from=' + txt_from + '&txt_body=' + txt_body + '&captcha_code=' + captcha_code + '&txt_number=' + txt_number;
if (txt_body == '' || txt_number == '' || txt_from == '' || captcha_code == '') {
$('.alertsuccess').fadeOut(200).hide();
$('.alerterror').fadeIn(200).show();
//$('.alert-box').fadeIn(200).show();
} else {
$.ajax({
type: "POST",
url: "sendsms.php",
data: dataString,
success: function(response) {
response = $.parseJSON(response);
if (response) {
if (response.status == 'success') {
$('.alertsuccess').fadeOut(200).hide();
$('.alertsuccess').fadeIn(200).show();
$('.alerterror').fadeOut(200).hide();
document.getElementById('captcha').src = 'securimage/securimage_show.php?' + Math.random();
$('#txt_from').val('');
$('#txt_body').val('');
$('#txt_number').val('');
$('#captcha_code').val('');
} else if (response.status == 'failed') {
$("#divToErrorMessage").html(response.message);
}
}
}
});
}
return false;
});
});

您从哪里获得value=“index.html”?谢谢你把它和你的HTML放在一起。如果手动编写HTML,只需在隐藏输入中键入页面名称。如果PHP生成所有页面,您可以使用$\u服务器[“请求URI”]$\u服务器[“脚本文件名”]$\u服务器[“脚本名称”]$\u服务器[“PHP自身”]$\u环境[“请求URI”]Pinoy?再次感谢:)
