从表格中删除-通过表格

Question

I have a HTML table that displays all my table entries. Also in the table is a delete button next to every SQL entry.

I want to be able to delete an entry the user selects. I've made the form to Post PHP_Self , and I'm passing in the index $i from the while loop as a reference:

$i = 0;

while($row = mysqli_fetch_array($result)){

    ?>

    <tr>
        <td>
            <? echo $row['uniqueIdentifier']; ?>
        </td>

        <td>
            <form action="<? echo $_SERVER['PHP_SELF']; ?>" method="post">
                <input type='hidden' name='remove_entrie_ID' value='<? echo $i; ?>' />
                <input type='submit' value='Delete' name='remove_entrie'>
            </form>
        </td>

    </tr>

    <?

    $i++;

}

So this is passed to itself, I now want to do a DELETE WHERE 'INDEX OF TABLE' == $i , type thing? I don't even know if this is possible.

if(isset($_POST['remove_entrie'])){

    $index = $_POST['remove_entrie_ID']
    echo "Index: " . $index;

    //mysqli_query($con, "DELETE FROM Users WHERE INDEX = '$index'");
}

I'm basically using the $i to pick out the index of how the table was loaded, and then using that to pick out which row I want to delete. But I have a feeling this can't be done?

I basically want to delete a row the user has selected from the table.

You don't need $i variable. Just make simple modification in your list:

while($row = mysqli_fetch_array($result)){
?>
<tr>
    <td>
        <? echo $row['uniqueIdentifier']; ?>
    </td>

    <td>
        <form action="" method="post">
            <input type="hidden" name="remove_entrie_ID" value="<? echo $row['uniqueIdentifier']; ?>" />
            <input type="submit" value="Delete" name="remove_entrie">
        </form>
    </td>

</tr>

<?

}

It is also good idea to escape specials chars etc in your post variable to avoid sql injection.
