Okay so I was making a code, the code is given below. Now whenever I click on the submit button, the page loads and nothing happens. The same form is displayed again and no results are displayed as per the code.

My code is:

What may be the issue here? I can't use POST as PHPStorm POST code doesn't work. Any help why the page loads but doesn't echo the result and remains same as it is?

<html>
<head><title>
    Creating a Table!
</title>

<style>
.h1 {text-align: center}
</style>


</head>


<body>

<?php

if(isset($_GET['button_create'])) {

$conn = mysqli_connect("localhost","root","");

if(!conn) {
    die("Connection failed!");
}

mysqli_select_db($conn,"test");

$tablename = $_POST['table_name'];

$row1name = $_POST['row1_name'];
$row1input = $_POST['row1_input'];
$row1length = $_POST['row1_length'];

$row2name = $_POST['row2_name'];
$row2input = $_POST['row2_input'];
$row2length = $_POST['row2_length'];

$row3name = $_POST['row3_name'];
$row3input = $_POST['row3_input'];
$row3length = $_POST['row3_length'];

$sql = "CREATE TABLE $tablename (".
    "$row1name $row1input($row1length),".
    "$row2name $row2input($row2length),".
    "$row3name $row3input($row3length) )";

$retval = mysqli_query($conn,$sql);

if(!$retval) {
    echo("Error. Queries couldn't be done <br />").mysqli_error();
}

echo("Table created successfully! <br />");
echo("Follow the navigation window below now! <br />");

mysqli_close($conn);

}

else {

?>

Hi there,

The problem is in your code (form uses GET and not POST) and has nothing to do with PhpStorm -- you will get the same result in another IDE/editor.

Same on StackOverflow: https://stackoverflow.com/questions/50325888/php-submit-button-doesnt-have-any-effect-phpstorm
