How Can I Submit an Array from an HTML Form Without JavaScript?

POST an Array from an HTML Form Without JavaScript

This question proposes a challenge of sending an array of tuples from a complex HTML form to simplify server-side processing. The form includes two sections: one for user information and another for a list of trees. The goal is to avoid using JavaScript and support a wider user base.

The solution presented in the answers involves structuring the form inputs as follows:

<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]">

This structure results in the following $_POST array in PHP format:

$_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'
        )
    )
)

By following this approach, the server can access the user and tree data as an array of arrays, facilitating efficient processing without the need for JavaScript.
