Sweet Alert to $_POST - mysql

Question

I want to update data using php/mysql but beeing a new programmer in PHP.
I am wondering how I could:
1- Use an application form with Sweet Alert so that in my CRUD when I may click on 'Edit', and instead of being redirected to process replacing it with one easy step?
2- Send data coming from this completed form when I click on a button in the PHP's $_POST superglobal so that I'd be able to test the data and update my database.
Can someone help me please? Here is my code from crud.php:
<?php
session_start(); // on a besoin des variables de session
include_once("inc/inc_header.php");
include_once("inc/inc_nav.php");
include_once('connection.php');
include_once('oldconnection.php');
//include_once('../dist/libs/grocery-crud-1.5.8.1/application/libraries/Grocery_CRUD.php');
//include_once('../dist/libs/grocery-crud-1.5.8.1/application/libraries/image_moo.php');
?>
<?php
if(isset($_GET['oneDeleted']) && $_GET['oneDeleted'] == true && isset($_GET['stopUser']))
{
?>
<h2>
<?php
extract($_GET);
echo $stopUser." a bien ete supprime. ";
?>
</h2>
<?php
}
?>
<?php
// on recupere les donnees d'obis.
$cruder = $con->prepare("SELECT * FROM user");
$cruder->execute();
$abonnes = $cruder->fetchAll(); // on met ses donnees personnelles dans $mesInfos, elles serviront en placeholder.
foreach($abonnes as $abonne)
{
$keepId = $abonne['user_id'];
?>
<?php /*if(isset($_GET['oneDeleted'] && $_GET['oneDeleted'] == true) && isset($_GET['stopuser']))
{ ?>
<h2>
<?php
extract($_GET);
echo $stopUser." a bien ete supprime.";
?>
</h2>
<?php }*/ ?>
