Question

I am having problem with $_GET array. More precisely I’m retrieving data from mysql database and writing as output like this;

while ($reg_pins = mysqli_fetch_assoc($r)){
    echo "<tr>";
    echo "<td><span class='tmp_id'>" . $reg_pins['tmp_id'] . ")</span></td>";
    echo "<td>&nbsp;</td>";
    echo "<td><span class='tmp_id'>" . $reg_pins['rights'] . "</span></td>";
    echo "<td>&nbsp;</td>";
    echo "<td><span class='tmp_id'>" . $reg_pins['reg_pin'] . "</span></td>";
    echo "<td>&nbsp;</td>";
    echo "<td><a class='del_a' href='" . $_SERVER['PHP_SELF'] . "?delete=" . $reg_pins['tmp_id'] . "' >Delete&nbsp;Key</a></td>";
    echo "</tr>";
}

(I didn’t write whole connection and other statements what is needed for retrieving data from database)

This is work perfectly, but I want to delete some of this data, so I can not write code to delete it.

I am interested in how I can manipulate with this situation (with $_GET method) to achieve my goal?

I’m not sure I understand your question, but apparently you’re asking how to send information to a php script when the user clicks on a link.

If that’s your question, then you have to use url parameters. They are codified as follows:

http://yoururl.com?param_name=value&param_name2=value2

And so on and so on…
What you’re doing is adding parameters after the “?” and you separate them with the “&” sign. Values can have anything you want (numbers, strings, etc).

On your php script, you catch the values as follows:

$value1 = $_GET['param_name'];
$value2 = $_GET['param_name2'];

Does that help you? Let me know if you have more questions.
