PHP/HTML Add A remove button

Question

I have the code below to retrieve rows from a database where the username column matches the base directory name:

$username =  basename(dirname(__FILE__));
$user         


        

Answer 1

echo "<a href='deletepage.php?id=$someid'>X</a>";

create a page that with _GET['id'] parameter;

And on that page i.e. deletepage.php?id=15

$sql = "DELETE table FROM table WHERE id = ".(int)$_GET['id']

mysql_query($sql);

header("location: previoudpage.php");

Answer 2

You could just add a submit button linking to the same page like

while ($row = mysql_fetch_array($result)) { //loop
  extract($row);
  $html .= "<li><span style=\"font-family: verdana;\"><a href=\"{$link}\" target=\"_blank\">{$link}</a>  <form action=\"{$_SERVER["PHP_SELF"]}\" method=\"post\">
    <input type=\"hidden\" value=\"{link}\" name=\"Delete\" />
    <input type=\"submit\" value=\"Delete\" />
    </form></span> <span style=\"color:white;  font-family: verdana;\">- {$notes}</span></li>";
  }

Then in your page do something like

if (!empty($_POST["delete"])){
     $query = "DELETE FROM links where link = '{$_POST["Delete"]}'";
     mysql_query($query);
}

That's the basic idea of how I would do it
