Question

I’m new to PHP, so please pardon me for anything stupid.

I’m creating a phonebook (as my first PHP project) with the ability to delete an entry from the database.
Here’s my code:

<?php for ($i = 0; $i < count($entries); $i++) { ?>
    <tr <?php echo ($i % 2) ? "class='alt'" : ""; ?>>
        <td><?php echo "0" . $entries[$i]["id"] . "."; ?></td>
        <td><?php echo $entries[$i]["name"]; ?></td>
        <td><?php echo "+92" . $entries[$i]["number"]; ?></td>
        <td>
            <form action="delete.php" method="post">
                <input type="submit" value="Delete" id="delete">
            </form>
        </td>
     </tr>
<?php } ?>

Question: How do I “POST” the ID ($entires[i$]["id"]) to delete.php?

Answer 1

You can use a hidden input to post the id.

<input type="hidden" value="1" name="id"/>

Just put the form around your <table /> and add the hidden input to the <td /> that already contains the id.

<form action="delete.php" method="post">
<?php for ($i = 0; $i < count($entries); $i++) { ?>
    <tr <?php echo ($i % 2) ? "class='alt'" : ""; ?>>
        <td><?php echo "0" . $entries[$i]["id"] . "."; ?>
            <input type="hidden" name="id" value="<?php echo $entries[$i]["id"];?>" />
        </td>
        <td><?php echo $entries[$i]["name"]; ?></td>
        <td><?php echo "+92" . $entries[$i]["number"]; ?></td>
        <td>
           <input type="submit" value="Delete" id="delete">
        </td>
     </tr>
<?php } ?>
</form>
