Submiting a Form without Refreshing the page with jQuery and Ajax Not updating MySQL database.
- by HEEEEEEELP
I'm a newbie to JQuery and have a problem, when I click submit button on the form everything says registration was successful but my MYSQL database was not updated everything worked fine until I tried to add the JQuery to the picture.
Can someone help me fix this problem so my database is updated?
Thanks
Here is the JQuery code.
$(function() {
$(".save-button").click(function() {
var address = $("#address").val();
var address_two = $("#address_two").val();
var city_town = $("#city_town").val();
var state_province = $("#state_province").val();
var zipcode = $("#zipcode").val();
var country = $("#country").val();
var email = $("#email").val();
var dataString = 'address='+ address + '&address_two=' + address_two + '&city_town=' + city_town + '&state_province=' + state_province + '&zipcode=' + zipcode + '&country=' + country + '$email=' + email;
if(address=='' || address_two=='' || city_town=='' || state_province=='' || zipcode=='' || country=='' || email=='') {
$('.success').fadeOut(200).hide();
$('.error').fadeOut(200).show();
}
else
{
$.ajax({
type: "POST",
url: "http://localhost/New%20Project/home/index.php",
data: dataString,
success: function(){
$('.success').fadeIn(200).show();
$('.error').fadeOut(200).hide();
}
});
}
return false;
});
});
Here is the PHP code.
if (isset($_POST['contact_info_submitted'])) { // Handle the form.
// Query member data from the database and ready it for display
$mysqli = mysqli_connect("localhost", "root", "", "sitename");
$dbc = mysqli_query($mysqli,"SELECT users.*, contact_info.*
FROM users
INNER JOIN contact_info ON contact_info.user_id = users.user_id
WHERE users.user_id=3");
$user_id = mysqli_real_escape_string($mysqli, htmlentities('3'));
$address = mysqli_real_escape_string($mysqli, htmlentities($_POST['address']));
$address_two = mysqli_real_escape_string($mysqli, htmlentities($_POST['address_two']));
$city_town = mysqli_real_escape_string($mysqli, htmlentities($_POST['city_town']));
$state_province = mysqli_real_escape_string($mysqli, htmlentities($_POST['state_province']));
$zipcode = mysqli_real_escape_string($mysqli, htmlentities($_POST['zipcode']));
$country = mysqli_real_escape_string($mysqli, htmlentities($_POST['country']));
$email = mysqli_real_escape_string($mysqli, strip_tags($_POST['email']));
//If the table is not found add it to the database
if (mysqli_num_rows($dbc) == 0) {
$mysqli = mysqli_connect("localhost", "root", "", "sitename");
$dbc = mysqli_query($mysqli,"INSERT INTO contact_info (user_id, address, address_two, city_town, state_province, zipcode, country, email)
VALUES ('$user_id', '$address', '$address_two', '$city_town', '$state_province', '$zipcode', '$country', '$email')");
}
//If the table is in the database update each field when needed
if ($dbc == TRUE) {
$dbc = mysqli_query($mysqli,"UPDATE contact_info
SET address = '$address', address_two = '$address_two', city_town = '$city_town', state_province = '$state_province', zipcode = '$zipcode', country = '$country', email = '$email'
WHERE user_id = '$user_id'");
}
if (!$dbc) {
// There was an error...do something about it here...
print mysqli_error($mysqli);
return;
}
}
Here is the XHTML code.
