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

Non-JavaScript POST Array Submission from HTML Form

Posting an array of tuples from an HTML form without JavaScript can be a challenge. This question addresses the task of representing a 'User' with an array of 'Trees' within a single form submission.

The provided solution leverages HTML input field naming conventions to organize data into associative arrays within the PHP $_POST superglobal. Here's how it works:

<!-- Example of User Form with array of Trees -->
<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]">

When the form is submitted, PHP automatically parses the input values into the $_POST array in the following 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'
        )
    )
)

This approach provides a structured way to access both the 'User' and 'Tree' data without relying on JavaScript or complex form processing. It accommodates multiple 'Trees' for a single 'User' while maintaining a clean and organized data representation in PHP.
