当用户注册新帐户时,我正在检查数据库中是否存在电子邮件。当我输入数据库中的电子邮件时,“EmailMessage”不会出现。代码位于:
validateemail.js
function validateemail() {
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
var response = xmlhttp.responseText;
response = response.replace(/^\s+|\s+$/g,'')
if(response == 'error'){
document.getElementById("EmailMessage").innerHTML='This e-mail address is already taken! If you believe this is in error, please email <a href="mailto:support@pumpspy.com">support@pumpspy.com</a>';
document.getElementById("newemail").focus();
document.getElementById("email_notice").style.display="none";
document.getElementById("submit_new_account").disabled =true;
}
else {
document.getElementById("EmailMessage").innerHTML="";
}
}
}
var newemail = document.getElementById("newemail").value;
if(newemail!=""){
xmlhttp.open("GET","Checkemail.php?email="+newemail,true);
xmlhttp.send();
}
else{
document.getElementById("EmailMessage").innerHTML="";
document.getElementById("submit_new_account").disabled =false;
}
}
Checkemail.php
$emailexists = $_GET['email'];
$sql = executeQuery("SELECT email from tbl_Users WHERE email = '$emailexists'");
$i = getNumRows($sql);
if ($i !=0) {
echo "error";
}else {
echo "pass";
}
---
<input type="text" id="newemail" name="newemail" maxlength="60" size="27" onblur="validateemail();"/>
</div>
<div id="EmailMessage" style="color:#F00"></div>
答案 0 :(得分:0)
尝试:$sql = executeQuery("SELECT email from tbl_Users WHERE email = '".$emailexists."'");
另外,请考虑完全更改代码(问题,安全问题)......
