从输入创建数组？

Question

I wish to store an arbitrary number of answers to a question on a form in a single field (json).

So the inputs may be something like:

Your Jobs:

• job title
• start date
• end date

I know I can call the input <input name="job_title[]"> and these would all be listed as an array under job_title. But is there anyway to have all three inputs listed under a keyed array just by naming the inputs in a specific way, something like:

[jobs => [['job_title' => 'xyz', 'start_date` => 'xyz', 'send_date` => 'xyz'], ....]

Or would I need to build this manually in php with loops?

Answer 1

Do you want to create an array based on the Posted input value? Just use the foreach loop with the $_POST variable like

<?php 
if (isset($_POST)) {
    foreach ($_POST as $key => $value) { // for every post value
        $array[] = array( // we create a array based on the name and the value
            $key => $value
        );
    }
    var_dump($array); // dump the array
}
?>
<form method="POST">
    <input type="text" name="job title" value="xyz">
    <input type="text" name="start date" value="xyz">
    <input type="text" name="send date" value="xyz">
    <!-- any other input -->
    <button type="submit">sd</button>
</form>

The var_dump($array) will give you

array(2) { ["job_title"]=> string(3) "xyz" ["start_date"]=> string(3) "xyz" } array(1) { ["send_date"]=> string(3) "xyz" }

To create JSON from the array just do

echo json_encode($array)
