First of all you can try check your url.Is it correct or no.For example send anything via ajax and show the response at console log.If it is not working thats mean your url is wrong.

Ajax : one ajax request for another forms

I have 3 contact form in one page (header, page, footer). How i can create one ajax request for all form ? I want when user click each one form send data fron only this form. Just now send from all forms. I used hasClass for determining from which class sending data, but i can't it
HTML:
<form id="contact-form1" method="POST" class="d-flex form">
<input type="text" class="simple-input" id="name" placeholder="Name">
<input type="text" class="simple-input" id="email" placeholder="Email address">
<textarea class="quession-input" id="msg" placeholder="Your question"></textarea>
<div class="checkboks custom-sq">
<input type="checkbox" class="checked-checkbox" name="myCheckboxes[]" id="box1" checked="checked" value="true" />
<label for="box1" class="checkboks-text"><?php echo the_field('checkbox_text', 'option'); ?></label>
</div>
<button type="submit" id="submit" class="danger-btn submit1"><?php echo the_field('btn_send', 'option'); ?></button>
</form>
<form id="contact-form" method="POST" class="d-flex form">
<input type="text" class="simple-input" id="hy_name" placeholder="Name">
<input type="text" class="simple-input" id="hy_email" placeholder="Email address">
<textarea class="quession-input" id="hy_msg" placeholder="Your question"></textarea>
<div class="checkboks custom-sq">
<input type="checkbox" id="box3" class="checked-checkbox" checked="checked" />
<label for="box3" class="checkboks-text"><?php echo the_field('checkbox_text', 'option'); ?></label>
</div>
<button type="submit" id="submit" class="danger-btn hy-submit submit2"><?php echo the_field('btn_send', 'option'); ?></button>
</form>
Ajax:
jQuery('.submit, .hy-submit').on('click', function(e) {
e.preventDefault();
// All data from form
var str = $(this).closest('form').serialize();
// Get current page url
var page_url = window.location.toString();
// Vars
var name = jQuery('#name').val();
var hy_name = jQuery('#hy_name').val();
var email = jQuery('#email').val();
var hy_email = jQuery('#hy_email').val();
var msg = jQuery('#msg').val();
var hy_msg = jQuery('#hy_msg').val();
var subj = jQuery('#subj').val();
var obj=$(this);
if($(obj).hasClass('hy-submit')){
validatehyEmail(hy_email);
if (hy_msg == '' || hy_email == '' || validatehyEmail(jQuery('#hy_email').val()) == false) {
validatehyEmail(hy_email);
validateText(jQuery('#hy_msg'));
validateText(jQuery('#hy_name'));
return false;
}
console.log('submit');
} else if ($(obj).hasClass('submit')) {
validateEmail(email);

validateEmail(email);
validateText(jQuery('#msg'));
validateText(jQuery('#name'));
return false;
}
console.log('submit');
}
// Get checkbox value
var chkElem = document.getElementsByName("myCheckboxes[]");
var choice ="";
for(var i=0; i< chkElem.length; i++)
{
if(chkElem[i].checked)
choice = choice + chkElem[i].value;
}
jQuery.ajax({
type: "post",
url: ajaxactionurl,
data: "action=send_email&" + str + "&myCheckboxes=" + choice + "&url=" + page_url,
success: function (response) {
jQuery('#contact-form input').val('');
jQuery('#contact-form textarea').val('');
jQuery('.submit').text('Done!');
},
error: function (jqXHR, textStatus, errorThrown) {
console.log(textStatus);
}
});
});
PHP:
add_action('wp_ajax_nopriv_send_email', 'send_email');
add_action('wp_ajax_send_email', 'send_email');
function send_email() {
$checkbox = $_POST['myCheckboxes'];
if (isset($checkbox)) {
echo $checkbox;
}
$headers = 'Content-Type: text/html; charset="utf-8"';
$name = $_POST['name'];
$url = $_POST['url'];
$hy_name = $_POST['hy_name'];

$message .= (!empty($email)) ? '<p><strong>User Email</strong> : '. $email .'</p>' : '';
$message .= (!empty($msg)) ? '<p><strong>User Message</strong> : '.$msg .'</p>' : '';
$message .= (!empty($checkbox)) ? '<p><strong>Checkboxs</strong> : '.$checkbox .'</p>' : '';
$message .= (!empty($url)) ? '<p><strong>Url:</strong> : '.$url .'</p>' : '';
$message .= (!empty($hy_name)) ? '<p><strong>User Name</strong> : '.$hy_name .'</p>' : '';
$message .= (!empty($hy_email)) ? '<p><strong>User Email</strong> : '.$hy_email .'</p>' : '';
$message .= (!empty($hy_msg)) ? '<p><strong>User Message</strong> : '.$hy_msg .'</p>' : '';
$message .= '</body></html>';
echo mail($to, $subject, $message, $headers);
return $msg;
die();
}

Use form id attribute and use preventDefault method to prevent the forms from submitting.
$('#form-id').preventDefault();

how to make a update in MySQL using checkbox

I would like to know how a multiple update in MySQL with checkbox because I'm not getting the id attribute checkbox someone could help me?
HTML code
<form method="post" action="../sys/fav.php">
<input type="hidden" id="id_photo" name="id" value="">
<div class="col-md-12">
<p align="right"><button class="btn btn-primary" id="final" name="final">Send</button></p>
</div>
<?php
require "../sys/connect.php";
$email = $_GET['email'];
$sql = mysqli_query($mysqli, "SELECT * FROM gallery WHERE email ='$email'");
while($row = mysqli_fetch_array($sql)){
$id = $row['id'];
$name = $row['nome_galeria'];
$emailcontact = $row['email_contact'];
$pass = $row['pass'];
$email = $row['email'];
$img = $row['img'];
print"<div class=\"col-lg-3 col-md-4 col-sm-6 col-xs-12\">
<input type=\"hidden\" name=\"contact\" value=\"$emailcontact\">
<input type=\"hidden\" name=\"login\" value=\"$email\">
<input type=\"hidden\" name=\"pass\" value=\"$pass\">
<input type=\"hidden\" name=\"name\" value=\"$name\">
<div class=\"hovereffect\">
<img id=\"he\" class=\"img-responsive\" src=\"../images/images/gallery/big/$img\" alt=\"$name\">
<div class=\"overlay\">
<div class=\"btn-group\" data-toggle=\"buttons\">
<label class=\"btn btn-primary cke\">
<input type=\"checkbox\" name=\"ck[]\" class=\"ck\" value=\"not\" id=\"ck_$id\"><i class=\"fa fa-heart\"></i>
</label>
</div>
</div>
</div>
</div>";
}
mysqli_close($mysqli)
?>
</form>
PHP Code
require "conexao.php";
if(isset($_POST['final'])){
$id = $_POST['id'];
foreach($_POST['ck'] as $ck){
$check = $ck;
$sql = mysqli_query($mysqli,"UPDATE gallery SET fav = '$check' WHERE id = '$id'")or die(mysqli_error($mysqli));
}
if($sql)
echo "Success!";
else
echo "Fail!";
}
Code Js to get the id of the checkbox
$("#final").click(function(){
var str = "";
var boxes = $(".ck");
for(var i = 0; i< boxes.length; i++){
if(boxes[i].checked == true){
var tmp = boxes[i].id.split("_");
str+=(i ? "," : "")+tmp[1];
}
}
document.getElementById('id_fotos').value=str;
});

You can get values of checkbox using below code and pass through ajax
var ckArray = new Array();
$.each($('input[name="ck[]"]:checked'),
function(index, ele){
ckArray.push($(ele).val());
});

Contact form - submit button not working

I'm following this extensive article (with sources) to make a contact form on a website. However, I need a slightly more complex form, with more fields and also a radio buttons group.
I simply added to the process.php and scripts.js files the additional fields I needed. Amongst the many errors I could get, the submit button simply doesn't work at all. I click on it and nothing happens. I'm a newbie in PHP and JS, so I don't know a proper way how to debug and understand where the problem is. Could you help me find it?
Here's my code:
EDIT:
This part actually doesn't work, because I get an empty field in the string yielded. Any idea? These are the non-required fields:
// ASCENSORI CONDOMINIO
if (empty($_POST["ascensoriCondominio"])) {
$ascensoriCondominio = "Valore non specificato";
} else {
$ascensoriCondominio = $_POST["ascensoriCondominio"];
}
// SCALE CONDOMINIO
if (empty($_POST["scaleCondominio"])) {
$scaleCondominio = "Valore non specificato";
} else {
$scaleCondominio = $_POST["scaleCondominio"];
}
// RISCALDAMENTO CONDOMINIO
if (empty($_POST["riscaldamento"])) {
$riscaldamento = "Valore non specificato";
} else {
$riscaldamento = $_POST["riscaldamento"];
}

Your form action is php/process.php and your ajax call is php/process.php. When you click the submit button the JS event for the form is triggered but doesn't render an alternate page and override the form action of the html. I'd suggest simplifying the steps of the interaction of the components to understand them better before trying to master the complexity of what you have here.

I reproduced your code in localhost and all works fine if delete the validator() function:
$("#condominiForm").on("submit", function (event) {
Without that, the jquery still prevents to submit blank inputs and when all filled, the ajax call is executed, all the fields sended and all works fine.
You can see this on: https://www.dropbox.com/s/eqc3vzxpwb0jmgj/test.png?dl=0
Try removing that part. Hope it helps to you!
UPDATE
Also, for sending the mail, add this part for sending better emails:
$reply = "your#mail.com";
$headers = "From: " . strip_tags($Subject) . "\r\n";
$headers .= "Reply-To: ". strip_tags($reply) . "\r\n";
$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n";
Now you can use html tags:
$Body = '<html><body>';
$Body .= '<your actual code with html tags>';
$Body .= '</body></html>';
UPDATE 2
You forgot to set a value for radio inputs:
<input .... value='0'> or <input ... value='Si'>

$("#condominiForm").onclick(function (event) {
you should use on click event to run your all j query code its good of your project because some time on submit is not working

Hiding/showing an element

I got this function that show and hide a container by clicking on a button "+show more" or "- Hide" depending on the current action. However it's not working. Any insight on why?
echo ' <br>
<img src="../img/back.png" /><br>
<button type="button" onclick="show_hide("pinfocontainer","hidepinfo");" class="sidebutton" id="hidepinfo">+ Show more</button>
<div class="hide" id="pinfocontainer">
<div class="editform">
<h1>Personal Info </h1>
<br>
<form action="" method="post">
<span></span>';
$sql = "SHOW COLUMNS FROM candidates";
$result = mysqli_query($con,$sql);
while($row = mysqli_fetch_array($result)){
$sql2 = "SELECT ".$row['Field']." FROM candidates WHERE ID='".$_GET["cid"]."'";
$result2 = mysqli_query($con,$sql2);
echo '<label class="editlabel"> '.$row['Field'].' : </label>';
while($row2 = mysqli_fetch_array($result2)){
echo '<input class="editinput" id="'.$row['Field'].'" name="'.$row['Field'].'" value="'.$row2[$row['Field']].'" type="text">';
}
echo '<br>';
}
echo '<input name="submit" type="submit" value=" Update " style="width:105%;">
<span></span>
</form>
</div>
</div>
<div style="display:inline-block;padding-left:15px;padding-right:15px;"> </div>
Function:
function show_hide(id, id2) {
var e = document.getElementById(id);
if(e.style.display == 'inline-block') {
e.style.display = 'none';
document.getElementById(id2).innerHTML = "+ Show More";
}
else {
e.style.display = 'inline-block';
document.getElementById(id2).innerHTML = "- Hide";
}
}

onclick="show_hide("pinfocontainer","hidepinfo");"
You close the attribute with the 2th " so change the " to '
onclick="show_hide('pinfocontainer','hidepinfo');"
You may escape the ' because you echo it
echo 'onclick="show_hide(\'pinfocontainer\',\'hidepinfo\');"';
