Nested-form is forbidden right? Then how to do this?

Question

I have project similar to this example.

<?php

if (isset($_POST['delete'])) {
  // Delete using id
}

if (isset($_POST['deleteAll'])) {
  // Delete using array name check
}

?>

<form method="POST" action="index.php" onsubmit="return validate()"> // First form
    <?php foreach ($rows as $row) : ?>
        <form method="POST" action="index.php" onsubmit="return validate()> // Second form
            <input type="checkbox" name="check[]" value="<?php $row['id'] ?>" />
            <input type="hidden" name="id" value="<?php $row['id'] ?>" />
            <input type="submit" name="delete" value="Delete" />
        </form>
    <?php endforeach ?>

    <input type="submit" name="deleteAll" value="Delete checked items" />
</form>

onsubmit used to use confirm function in javascript.

I already think about this and only can think to use nested-form.

second form and submit delete used to delete using ID.

first form and submit deleteAll used to delete all checked items.

if I delete second form,

and I click delete the id will be the last index of foreach.

So I will delete the last row, not the row I wanted to delete.

I already thinking and found no clue,

I hope someone here can give a clue.

Don't try to do it that way. You're just making it more complicated. A single form should suffice.

<form method="POST" action="index.php" onsubmit="return validate()">
  <?php foreach ($rows as $row) : ?>
      <input type="checkbox" name="check[]" value="<?php echo $row['id'] ?>" />
      <button name="delete" value="<?php echo $row['id']; ?>">Delete</button><br/>
  <?php endforeach ?>
  <input type="submit" name="deleteAll" value="Delete checked items" />
</form>

PHP

// handle single delete
if(isset($_POST['delete'])) {
  $id = $_POST['delete']; // individual ID
}

// handle mulitple selected checkboxes
if(isset($_POST['deleteAll'])) {
  $ids = $_POST['check'];
}
