Question

It gives me this error when I try to load the page: Notice: Undefined variable: row in C:\wamp\www\vitamin-k-tracker\testing-form-checkboxes.php on line 3

I figure there’s some error in $_POST[ $row[“id”] ] because it’s so basic.

<?php

if (isset($_POST[  $row["id"]  ]) && !empty($_POST[ $row["id"] ])){
    print_r($_POST);
}

?>



<form action="testing-form-checkboxes.php" method="POST">     
<?php $row["id"]= 'a'; ?>
<input type="checkbox" name="<?php echo $row["id"]; ?>" value="aa" />

<br /><br />
<input type="submit" value="Add Food to my Meal Planner Queue">

</form>

Answer 1

You are looking for $_POST[ $row["id"] ] before you define it. Move <?php $row["id"]= 'a'; ?> to line 1.
