How to get multiple values through one check box?

I would like to get an array from a checkbox with one [id] and one [date] for each record.

Here is my actual HTML / PHP :

<input type="checkbox" name="collection[][id]" value="<?php echo $row['id']; ?>" />
<input type="hidden" name="collection[][date]" value="<?php echo date(Ymd); ?>" />

I get this :

Array
(
    [0] => Array
        (
            [id] => 544826
        )

    [1] => Array
        (
            [date] => 20170426
        )

    [2] => Array
        (
            [id] => 608555
        )

    [3] => Array
        (
            [date] => 20170426
        )
)

And I would like this :

Array
(
    [0] => Array
        (
            [id] => 544826
            [date] => 20170426
        )

    [1] => Array
        (
            [id] => 608555
            [date] => 20170426
        )
)

Please, how could I proceed ?

you need to give same index i.e key for both id and date while push the value like this 

<input type="checkbox" name="collection[<?php echo $row["id"]; ?>][id]" value="<?php echo $row["id"]; ?>" />
<input type="hidden" name="collection[<?php echo $row["id"]; ?>][date]" value="<?php echo date(Ymd); ?>" />

Just copy paste this code, I have tested it and this will surely help you achieve what you want.

<form>
    <input type="checkbox" name="collection[<?php echo $row["id"]; ?>][id]" value="<?php echo $row["id"]; ?>" />
    <input type="hidden" name="collection[<?php echo $row["id"]; ?>][date]" value="<?php echo date(Ymd); ?>" />
    <input type="checkbox" name="collection[<?php echo $row["id"]; ?>][id]" value="<?php echo $row["id"]; ?>" />
    <input type="hidden" name="collection[<?php echo $row["id"]; ?>][date]" value="<?php echo date(Ymd); ?>" />
    <input type="submit">
</form>

<?php

print_r(array_values($_GET["collection"]));

Output:

  Array
    (
        0 => Array
            (
                [id] => 10
                [date] => 20170426
            )

        1 => Array
            (
                [id] => 20
                [date] => 20170426
            )

    )

Why don't you use the ID as the index of the checkbox? That way you just need to go trough the list. i.e:

<input type="checkbox" name="collection[<?php echo $row['id']; ?>]" value="<?php echo date(Ymd); ?>" />

So that way you'll have the following array in collenction (for the ones ticked): 

$collection = [
'id1' => 'date1',
'id2' => 'date2',
...
]

Simpler and more elegant. Hope this helps

From your comments, it sounds like you have some JavaScript that handles the data before it's submitted. If that's the case, you can add a data attribute to the checkbox. To use your example, you could call it data-valuetwo.

input type="checkbox" value="testuser" data-valuetwo="1">

Then, your JavaScript can use getAttribute to retrieve the value in your data-valuetwo attribute and handle it appropriately. It could look something like this:

var valuetwo = checkbox.getAttribute("data-valuetwo");
