I just want to know if it is possible to execute a PHP post request with ajax by click on a form submit button that does not have any text input. Say i have a form

```
<form action="connecting.php" id="connect" method="post" enctype="multipart/form-data">
  <input type="submit" name="userconnect" id="userconnect" value="connect">
</form>

```

And i want to execute this block of php code on submit button

**connecting.php**

```
<?php
require_once ("db.php");
$db = new MyDB();

session_start();

    if (isset($_POST['userconnect']))
    {
        $my_id = htmlspecialchars($_SESSION['log_id'], ENT_QUOTES, 'UTF-8');
        $user_id = (int) htmlspecialchars($_SESSION['userid'], ENT_QUOTES, 'UTF-8');
        $rand_num = rand();

        $hsql =<<<EOF
    SELECT COUNT(hash) as count FROM connect WHERE (user_one = '$my_id' AND user_two = '$user_id') OR (user_two = '$my_id' AND user_one = '$user_id');
EOF;

        $hret = $db->querySingle($hsql);

        if ($hret == 1)
        {
            echo "<script>alert('You are already connected to this user')</script>";
        }
        else
        {

            $usql = $db->prepare("INSERT INTO connect (user_one, user_two, hash) VALUES (:my_id, :user_id, :rand_num)");
            $usql->bindValue(':my_id', $my_id, SQLITE3_INTEGER);
            $usql->bindValue(':user_id', $user_id, SQLITE3_INTEGER);
            $usql->bindValue(':rand_num', $rand_num, SQLITE3_TEXT);

            $uret = $usql->execute();

            if (!$uret)
            {
                echo "Error connecting";
            }
            else
            {
                echo "Connection Sucessful";
            }
        }
    }

```

This is the ajax request i am trying to use

```
$("#connect").submit(function(e) {
e.preventDefault();
$.ajax({
    type: "POST",
    url: "connecting.php",
    data: $(this).serializeArray(), //the data is an issue cause of no text input in for 
    dataType: "json", 
    success: function(response) {
        console.log(response);
    },
    error: function(response) {
    }
});
});

```

This doesn't work because there is no data in the form for ajax to send but all data are in the PHP file. How do i execute the php file with ajax. Is there any way?
