How to select tables from MySQL Database in php? - php

Question

I am trying to create a form in PHP with MySQL involved.
The theme of this form, form.php, is all about drinks. There are thirteen tables -each table named after type of drink (Belgian beer, wine, soda, rum, ...) that all include only three columns: Id of the drink(PRIVATE KEY AUTO_INCREMENT), the name of the drink and the price (in char). The rest of the columns in other tables are the same, the values are different.
I want to create a dropdown that allows you to select tables from MySQL to add/delete data to the columns within the selected table.
Some names of tables, columns and form elements are named in Dutch.

These are the things I do know:
1)Php code to add data to database
<?php
if ( ! empty($_POST))
{
$mysqli = new mysqli('localhost','root','','welkom');
if ($mysqli ->connect_error)
{
die('connect error: '. $mysqli->connect_errno . ': ' . $mysqli->connect_error);
}
$sql = "INSERT INTO abdijbieren (naam, prijs) VALUES ('{$mysqli->real_escape_string($_POST['naam'])}','{$mysqli->real_escape_string($_POST['prijs'])}')";
$insert = $mysqli->query($sql);
if ($insert)
{
echo "Success! Row ID: {$mysqli->insert_id}";
}
else
{
die("Error: {$mysqli->errno} : {$mysqli->error}");
}
$mysqli->close();
}?>
2)Form
<form method="post" action="check.php"> <!--check.php is not made yet but when that happens it should be used to automatically update the selected table and auto-return to form.php -->
<input name="naam" type="text" placeholder="naam drank/snack" required><br>
<input name="prijs" type="text" placeholder="prijs" required><br>
<input type="submit" value="Submit form">
</form>
All I can do with it is to add data to one certain column.
If you know how I can solve this, you are my hero.

Answer 1

You can select table names like this:
SHOW TABLES FROM <your_database>
Also to select columns from a table:
SHOW COLUMNS FROM <your_table>
