How do I insert data from a form into multiple tables? - php

Question

How do I insert data from a form into multiple tables? This is what I have so far :
<?php
require 'db/connect.php';
$Apple = trim($_POST['Apple']);
$Orange = trim($_POST['Orange']);
$Banana = trim($_POST['Banana']);
if (empty($Apple) && empty($Orange) && empty($Banana)){
$error = "Please pick your fruits";
} else {
$insert = $db->prepare("INSERT INTO fruits (Apple, Orange, Banana) Values (?,?,?)");
$insert->bind_param("sss", $Apple, $Orange, $Banana);
?>
//HTML SECTION
<form action="" method="post">
<table>
<tr>
<td><label for="Apple">Apples :</label></td>
<td><input type="text" id="Apple" name="Apple"></td>
</tr>
<tr>
<td><label for="Orange">Oranges:</label></td>
<td><input type="text" id="Orange" name="Orange"></td>
</tr>
<tr>
<td><label for="Banana">Bananas:</label></td>
<td><input type="text" id="Banana" name="Banana"></td>
</tr>
<td>
<button type="submit" class="create" name="create">CREATE</button>
<a class="btn" href="index.php">BACK</a>
</td>
</tr>
</table>
What I would like to do is this - within the form, have another field (say tomatoes), that when the user clicks "submit", apple / orange / banana goes to the fruits table, and "tomato" goes to the "vegetables" table.
Does anyone know how to achieve this?

Answer 1

Here is what I finally came up with, I made the mistake of misplacing the binding code for "Tomato". One thing that I am still confused about, and am unsure about how to approach, is how I can make it to where when I click on a form field for the below example, it will populate a popup that shows current contents of the database, and allow you to copy contents of that popup(item) to the form field if needed. Another example would be a customers and products table, you make a form field to take a customer and a product, when you click on "product" form field, it populates with all products, and allows you to click on one of the populated products to assign to that customer.
<?php
require 'db/connect.php';
$Apple = trim($_POST['Apple']);
$Orange = trim($_POST['Orange']);
$Banana = trim($_POST['Banana']);
$Tomato= trim($_POST['Tomato']);
if (empty($Apple) && empty($Orange) && empty($Banana) && empty($Tomato)){
$error = "Please pick your fruits";
} else {
$insert = $db->prepare("INSERT INTO fruits (Apple, Orange, Banana) Values (?,?,?)");
$insert->bind_param("sss", $Apple, $Orange, $Banana);
$insert = $db->prepare("INSERT INTO veggies(Tomato) Values (?)");
$insert->bind_param("s", $Tomato);
?>
