I want to add have a form in my Wordpress dashboard that work with ajax but my request response is 400 Bad request
add_action('admin_footer', 'vitrin_admin_ajax');
function vitrin_admin_ajax() {
?>
<script>
(function($) {
$('.vitrin-private-message-form').submit(function(event) {
event.preventDefault();
jQuery.ajax({
url: '<?php echo admin_url('admin-ajax.php'); ?>',
type: 'post',
data: {
action: 'submit_vitrin_pm',
ppmcontent: jQuery('#pmcontent').val(),
ppmusers: jQuery('#pmusers').val(),
},
success: function(data) {
// jQuery('#datafetch').html(data);
alert(data)
}
});
})
})(jQuery);
</script>
<?php
}
?>
I also add:
add_action('wp_ajax_submit_vitrin_pm', 'submit_vitrin_pm');
add_action('wp_ajax_nopriv_submit_vitrin_pm', 'submit_vitrin_pm');
and
function submit_vitrin_pm() {
echo 'ssss';
die();
}
I checked, your ajax response is working, you didn't share your html form, i added a form for check.
add_action('admin_footer', 'vitrin_admin_ajax');
function vitrin_admin_ajax() {
?>
<form action="#" method="POST" class="vitrin-private-message-form">

(function($) {

event.preventDefault();
console.log('working')
jQuery.ajax({

I have written a code by watching some tutorial. What it does is, if one writes a message, it adds it to database without reloading. The problem is it doesnt show me the updated database. It shows the database that was at the time of loading. What function should i add in function() to be able to that. I dont have much knowledge of javascript so if you can add it in the code it will me really helpful. Thanks

Try this snippet, i think the problem is because your form doesn't send the message data to the database.
<div class="footer">
<form class="search_footer" name="sentMessage" id="contactForm" novalidate >
<input id='comment' autocomplete="off" autofocus="autofocus" type="text" name="new_message" placeholder="Type your message here.." required="required" class="textbox">

$(document).ready(function(){
$.ajax({

});
$('form').on('submit', function (e) {
e.preventDefault();
var data = $('#comment').val();
$.ajax({
type: 'POST',

success: function(response) {

jQuery AJAX submit form
(20 answers)
Closed last year.
Can anyone tell me why this bit of code isn't working?
<html>
<head>
<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script>
$(function () {
$('form').bind('submit', function () {
$.ajax({
type: 'post',
url: 'post.php',
data: $('form').serialize(),
success: function () {
alert('form was submitted');
}
});
return false;
});
});
</script>
</head>
<body>
<form>
<input name="time" value="00:00:00.00"><br>
<input name="date" value="0000-00-00"><br>
<input name="submit" type="button" value="Submit">
</form>
</body>
</html>
When I push submit nothing happens. In the receiving php file I'm using $_POST['time'] and $_POST['date'] to put the data in a mysql query but it's just not getting the data. Any suggestions? I'm assuming it's something to do with the submit button but I can't figure it out
The form is submitting after the ajax request.

This page has a simpler example

Here is a nice plugin for jQuery that submits forms via ajax:
http://malsup.com/jquery/form/
its as simple as:
<script src="http://malsup.github.com/jquery.form.js"></script>
<script>
$(document).ready(function() {
$('#myForm').ajaxForm(function() {
alert('form was submitted');
});
});
</script>
It uses the forms action for the post location.
Not that you can't achieve this with your own code but this plugin has worked very nicely for me!
JS Code
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/ libs/jquery/1.3.0/jquery.min.js">
</script>
<script type="text/javascript" >
$(function() {
$(".submit").click(function() {
var time = $("#time").val();
var date = $("#date").val();
var dataString = 'time='+ time + '&date=' + date;
if(time=='' || date=='')
{
$('.success').fadeOut(200).hide();
$('.error').fadeOut(200).show();
}
else
{
$.ajax({
type: "POST",
url: "post.php",
data: dataString,
success: function(){
$('.success').fadeIn(200).show();
$('.error').fadeOut(200).hide();
}
});
}
return false;
});
});
</script>
HTML Form
<form>
<input id="time" value="00:00:00.00"><br>
<input id="date" value="0000-00-00"><br>
<input name="submit" type="button" value="Submit">

<span class="error" style="display:none"> Please Enter Valid Data</span>

PHP Code
<?php
if($_POST)
{
$date=$_POST['date'];
$time=$_POST['time'];
mysql_query("SQL insert statement.......");
}else { }
?>
Taken From Here
type="button"
should be
type="submit"
In event handling, pass the object of event to the function and then add statement i.e.
event.preventDefault();
This will pass data to webpage without refreshing it.
$(document).ready(function(){
$('#userForm').on('submit', function(e){
e.preventDefault();
//I had an issue that the forms were submitted in geometrical progression after the next submit.
// This solved the problem.
e.stopImmediatePropagation();
// show that something is loading
$('#response').html("<b>Loading data...</b>");
// Call ajax for pass data to other place
$.ajax({
type: 'POST',
url: 'somephpfile.php',
data: $(this).serialize() // getting filed value in serialize form
})
.done(function(data){ // if getting done then call.
// show the response
$('#response').html(data);
})
.fail(function() { // if fail then getting message
// just in case posting your form failed
alert( "Posting failed." );
});
// to prevent refreshing the whole page page
return false;

I simply want to submit my form to the same page with ajax without page refresh. So my below code submits the form but $_POST values are not picked ... Am I submitting it properly. I don't get any error but I think my form is not submitting.
html form
<form action="" id="fixeddonation" name="fixeddonation" method="post">
<input type="hidden" class="donerProject" name="donerProject" value="test">
<input type="hidden" class="donersubProject" id="donersubProject" name="donersubProject" value="general">
<input type="hidden" class="donerLocations" id="donerLocations" name="donerLocations" value="general">
<input type="hidden" class="donationpagetype" name="donationpagetype" value="general">
<input type="hidden" class="projectadded" id="projectadded" name="projectadded" value="1">
<input type="hidden" value="302" id="pageid" name="pageid">
<div class="classsetrepet generalfixshow fullrow row fixed-page">
<div class="col-6 text-right">
<div class="prize">Fixed Amount £</div>
</div>
<div class="col-6">
<input type="text" id="oneoffamt" name="oneoffamt" class="oneoffamt validatenumber">
<span class="amt_error"></span>
</div>
</div>
<br>
<div class="row">
<div class="col-6"></div>
<div class="col-6">
<input type="submit" id="submit_gen_one" class="btn-block" value="submit" name="submit_gen_one">
</div>
</div>
</form>
Ajax code
jQuery('#fixeddonation').on('submit', function (e) {
e.preventDefault();
jQuery.ajax({
type: 'post',
url: 'wp-admin/admin-ajax.php',
data: jQuery('#fixeddonation').serialize(),
success: function (data) {
alert(data);
alert('form was submitted');
jQuery('#collapse2').addClass('in').removeAttr('aria-expanded').removeAttr('style'); jQuery('#collapse1').removeClass('in').removeAttr('aria-expanded').removeAttr('style');
}
});
return false;
});
Add a correct value to the action tag of your form and try this:
<script>
$(document).ready(function() {
var form = $('#fixeddonation');
form.submit(function(ev) {
ev.preventDefault();
var formData = form.serialize();
$.ajax({
method: 'POST',
url: form.attr('action'),
data: formData
}) .done(function(data) {
alert(data);
});
});
}); // end .ready()
</script>
Don't need return false as you already called preventDefault() first thing
First create Template
<?php
/* Template Name: Test */
get_header();
?>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js" type="text/javascript"></script>
<div id="primary" class="content-area">

<fieldset>
<label><i class="fa fa-file-text-o"></i> Register Form</label>
<input type="text" name="firstname" placeholder="Username" id="firstname">
<p id="firstname-error" style="display:none">Firstname Must Be Enter</p>
<input type="email" name="email" placeholder="Email address" id="email">
<p id="email-error" style="display:none">Email Must Be Enter</p>
<input type="submit" class="button" id="test" value="Register" >
</fieldset>
</form>
<script type="text/javascript">
jQuery('#test').on('click',function(e){
e.preventDefault();
var firstname = jQuery('#firstname').val();
var email = jQuery('#email').val();
if (firstname == "") {
jQuery('#firstname-error').show();
return false;
} else {
jQuery('#firstname-error').hide();
}
if (email == "") { jQuery('#email-error').show(); return false; }
else { jQuery('#email-error').hide(); }
jQuery.ajax({
type:"POST",
url:"<?php echo admin_url('admin-ajax.php'); ?>",
data: {
action: "test",
firstname : firstname,
email : email
},
success: function(results){
console.log(results);
jQuery('.register-message').text(results).show();
},
error: function(results) {
}
});
});
</script>
</main><!-- #main -->
</div><!-- #primary -->
after that create a function (function.php in wordpress)
add_action('wp_ajax_test', 'test', 0);
add_action('wp_ajax_nopriv_test', 'test');
function test() {
$firstname = stripcslashes($_POST['firstname']);
$email = stripcslashes($_POST['email']);
global $wpdb;
$q = $wpdb->prepare("SELECT * FROM wp_test WHERE email='".$email."' ");
$res = $wpdb->get_results($q);
if(count($res)>0)
{
echo "Email Allready Register ";
}
else
{
$user_data = array(
'firstname' => $firstname,
'email' => $email
);
$tablename = $wpdb->prefix.'test'; // if use wordpress
$user_id= $wpdb->insert( $tablename,$user_data );
echo 'we have Created an account for you';
die;
}
}
I have got this in my index.php
if (isset($_POST['PostSubm'])) {
$file=$_FILES['ImageTi'];
$file_name=$file['name'];
$file_tmp=$file['tmp_name'];
$file_size=$file['size'];
$file_error=$file['error'];
$file_extension=explode('.', $file_name);
$file_extension=strtolower(end($file_extension));
$allowed=array('jpg','png');
if (in_array($file_extension, $allowed)) {
if ($file_error===0) {
if ($file_size<=2097152) {
$file_new_name=generateRandomString(15).rand(0,100).'.'.$file_extension;
$_SESSION['file_new_name']=$file_new_name;
$file_destination='../uploads/'.$file_new_name;
if (!move_uploaded_file($file_tmp,$file_destination)) {
echo "<p class='filerror'>Error</p>";
exit();
}
}
}
}
}
And this HTML
<form method="post" class="Postshf" enctype="multipart/form-data">
<input type="file" name="ImageTi" id="PhotoPost">
<textarea name="Text" placeholder="Your text here" maxlength="400" class="descrp"></textarea>
<input type="submit" name="PostSubm" class="PostSub" value="Post">
</form>
And i have also got this in my jquery.js
$(".Postshf").submit(function(){
var descrp=$(".descrp").val();
var s=$(".sasa").text();
$.ajax({
type: "GET",
url: '../files/connect.php',
data: "Namess="+names+"&Left="+left+"&top="+top+"&d="+descrp+"&r="+s,

{
alert(data);
}
});
});
So my goal is to move file that was uploaded to "ImageTi" and at the same time insert the name of that file to database.But i am having no luck
I am trying to post data and receive response using jQuery Ajax Post and I am not sure why my code is not working.
<script>
$(document).ready(function(){
$('#login').click(function(){
$.ajax({
type: 'POST',
url: 'http://code.com/backend/test3',
dataType: 'json',
data: {"username":"akllkkj","password":"kljjkjkl"},
cache: false,
success: function(data){
console.log(data.stack);
console.log(data.key);
},
error:function(){
alert("failure");
}
});
return false;
});
});
</script>
<form autocomplete="off" class="ui fluid form segment" method="post">
<div class="ui fluid form segment">
<div class="two fields">
<div class="field">
<label>Email/Username</label>
<input placeholder="Email/Username" name="username" id="username" type="text">
</div>
<div class="field">
<label>Password</label>
<input placeholder="Password" name="password" id="password" type="password">
</div>
</div>
<input type="button" class="ui fluid submit button" name="dosubmit" value="Submit" id="login" />
</div>
</form>
And my test3 page contains:
<?php
if(isset($_POST['username']) && isset($_POST['password'])) {
$arr = array(
'stack'=>'overflow',
'key'=>'value'
);
echo json_encode($arr);
}
?>
This has worked for me:
$('#form').submit(function (event) {
event.preventDefault();
var data = $('#form').serialize();
$.ajax({
type: 'post',
dataType: 'json',
data: data
}).done(function (resp) {
console.log(resp);
});
});
And on the php side of things, you may need something like this:
header('Content-Type: application/json');
echo json_encode($arr);
Try this. It will work.
<script type="text/javascript">
$(document).ready(function(){
$('#login').click(function(){
$.ajax({
type: 'POST',
url: 'http://code.com/backend/test3.php',
dataType: 'json',
data: {"username":"akllkkj","password":"kljjkjkl"},
async: true,
success: function(data){
var obj = jQuery.parseJSON(data);
if(obj)
{
for(i=0;i<obj.length;i++) {
console.log(obj[i].stack);
console.log(obj[i].key);
}
} else {
console.log("Empty Result");
}
},
error:function(){
alert("failure");
}
});
});
});
<script>
And you test3.php script will be:
<?php
$arr=array();
if(isset($_POST['username']) && isset($_POST['password'])) {
$arr[] = array(
'stack'=>'overflow',
'key'=>'value'
);
}
echo json_encode($arr);
?>
