I'm trying to validate if a username is already taking or not. This onchange of an input field. I already got other checks but they don't work anymore since I added the ajax call. I'm new to ajax and javascript so the error can be there.
the html form:
<form action="test" method="post"> <input id="username" type="text" placeholder="Gebruikersnaam" name="username" required onchange="checkUserName()"> <br> <input id="email" type="text" placeholder="Email" name="email" required onchange="validateEmail()"> <br> <input id="pass1" type="password" placeholder="Type wachtwoord" name="password1" required> <br> <input id="pass2" type="password" placeholder="Bevestig wachtwoord" name="password2" required onchange="passwordCheck()"> <br> <select name="typeAccount"> <option value="bedrijf">Bedrijf</option> <option value="recruiter">Recruiter</option> <option value="werkzoekende">Talent zoekt job</option> </select> <p id="demo1"> </P> <p id="demo2"> </P> <button type="submit">Scrijf mij in!</button> </form>
the javascript that I use:
<script src="jquery.js">
function passwordCheck(){
var password1 = document.getElementById('pass1').value;
var password2 = document.getElementById('pass2').value;
if(password1 !== password2){
document.getElementById("pass1").style.borderColor = "#ff3333";
document.getElementById("pass2").style.borderColor = "#ff3333";
}else{
document.getElementById("pass1").style.borderColor = "#1aff1a";
document.getElementById("pass2").style.borderColor = "#1aff1a";
}
}
function validate(email){
var re = /^(([^<>()[\]\\.,;:\s@\"]+(\.[^<>()[\]\\.,;:\s@\"]+)*)|(\".+\"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/;
return re.test(email);
}
function validateEmail(){
var email = document.getElementById('email').value;
if(validate(email)){
document.getElementById("email").style.borderColor = "#1aff1a";
}else{
document.getElementById("email").style.borderColor = "#ff3333";
}
}
function checkUserName(){
var username = document.getElementById('username').value;
if(username === ""){
document.getElementById("username").style.borderColor = "#ff3333";
}else{
$.ajax({
url: "userCheck.php",
data: { action : username },
succes: function(result){
if(result === 1){
document.getElementById("username").style.borderColor = "#1aff1a";
}else{
document.getElementById("username").style.borderColor = "#ff3333";
}
}
});
}
}
</script>
The php script I use this is in a different file:
<?php
include("connect.php");
$connect = new Connect();
$username = mysql_real_escape_string($_POST['username']);
$result = mysql_query('select username from usermaindata where username = "'. $username .'"');
if(mysql_num_rows($result)>0){
echo 0;
}else{
echo 1;
}
?>
The script and the html form is in the same html-file and the php is in a seperate PHP-file. I just want to check if the name is already in the database or not.
I assume your database connection is perfect.
$username = mysql_real_escape_string($_POST['username']);
change above code to
$username = mysqli_real_escape_string($db_connection,$_REQUEST['action']);
because in your ajax you're doing like
$.ajax({
url: "userCheck.php",
data: { action : username },
succes: function(result){
if(result === 1){
document.getElementById("username").style.borderColor = "#1aff1a";
}else{
document.getElementById("username").style.borderColor = "#ff3333";
}
}
});
You have not specified request type and you're fetching value using $_POST
with different variable name username
which is actually value You should use $_REQUEST['action']
And make sure you've added jquery.js
file in your html.
