POST an Array from an HTML Form without JavaScript

Question:

Can an array of tuples be natively POSTed from an HTML form without using JavaScript? The form consists of two parts: "User" and "Tree," where multiple trees can be associated with each user.

Answer:

Yes, it is possible to POST an array from an HTML form without using JavaScript. Here's how:

HTML Markup:

<input type="text" name="firstname">
<input type="text" name="lastname">
<input type="text" name="email">
<input type="text" name="address">

<input type="text" name="tree[tree1][fruit]">
<input type="text" name="tree[tree1][height]">

<input type="text" name="tree[tree2][fruit]">
<input type="text" name="tree[tree2][height]">

<input type="text" name="tree[tree3][fruit]">
<input type="text" name="tree[tree3][height]">

PHP Processing:

In PHP, the POSTed data will be available in the $_POST array as follows:

$_POST = array(
    'firstname' => 'value',
    'lastname' => 'value',
    'email' => 'value',
    'address' => 'value',
    'tree' => array(
        'tree1' => array(
            'fruit' => 'value',
            'height' => 'value'
        ),
        'tree2' => array(
            'fruit' => 'value',
            'height' => 'value'
        ),
        'tree3' => array(
            'fruit' => 'value',
            'height' => 'value'
        )
    )
)

This structure allows you to easily access the User information and the array of Trees associated with it.
