no response when form is sent - php

Question

I am trying to crewate a form fro listing databases on mysql, select one from the radio list and create a table with required parameters but it acts like it isn't even submitting. I see the url change but my code isn't running at all.
This is the form data:
SELECT DATABASE TO WORK WITH
<form action = "createtable.php" action = "post">
<?php
$query = "SHOW DATABASES";
$result = mysql_query($query, $connect);
if(!$result){echo mysql_error(); var_dump($result);
var_dump($connect); var_dump($query);}
while ($row = mysql_fetch_array($result))
{echo '<input type = "radio" name = "db"/>' . $row[0] . "<br>";}
?>
<input type = "text" name = "text" />
<input type = "submit" name = "submit" value = "submit" />
</form>
and the code to execute is:
<?php
if(isset($_POST['submit'])){
echo 'submit done';
$db = $_POST['db'];
$query = "USE $db";
$result = mysql_query($query, $connect);
if(!$result){echo 'no' . mysql_error();}
echo 'working';
$table = 'rio';
$id = 'id';
$idtype = 'int';
$idno = '11';
$staffmenu = 'staffmenu';
$stafftype = 'varchar';
$staffno = '255';
$null = 'NOT NULL';
$ai = 'auto_increment';
$key = 'id';
$query ="CREATE TABLE staff
($id $idtype($idno) $null $ai,
$staffmenu $stafftype($staffno) $null,
subj varchar(255) NOT NULL,
PRIMARY KEY ($key))";
var_dump($query);
$result2 = mysql_query($query, $connect);
if(!$result2){echo mysql_error();}
//session_destroy();
}
?>
i tried to use a different variable to trigger the code asides submit but that didn't work either. Any help will be appreciated. I am also aware of the deprecation of mysql, but i'm not totally sure how to migrate to mysqli so please bear with me.

Answer 1

To post your form you need method = "post" instead of action = "post"
<form action = "createtable.php" method = "post">
instead of
<form action = "createtable.php" action = "post">
Also, You need to add the value in your radio input as well,
echo '<input type = "radio" name = "db" value="'.$row[0].'" />' . $row[0] . "<br>";

Answer 2

Change your form's method type to post
you haven't mentioned your form's submission type
