Question

For use with SQL query.

Is it possible to pass an OR through GET?

variable=value OR othervalue

Or is it just easier to define multiple variables and then make the SQL filter from the multiple variables.

Answer 1

You should pass your GET parameters like so:

script.php?variable[]=happy&variable[]=sad

In your script, these will be stored in $_GET[variable] as an array:

Array
(
    [0] => happy
    [1] => sad
)

You can then bind the parameters and send your statement (haven’t tested):

<?php
$link = mysqli_connect('localhost', 'my_user', 'my_password', 'world');

/* check connection */
if (!$link) {
    printf("Connect failed: %s\n", mysqli_connect_error());
    exit();
}

$type = '';

$query = 'SELECT column FROM bubbles WHERE variable IN (';

for($i = 0; $i < count($_GET[variable]); $i++) {
   $query .= '?';
   $type .= 's';
   if($i+1 < count($_GET[variable])) $query .= ', ';
}

$query .= ')';

$stmt = mysqli_prepare($link, $query);

call_user_func_array('mysqli_stmt_bind_param', array_merge(array($stmt, $type), $_GET[variable])); 

/* execute prepared statement */
mysqli_stmt_execute($stmt);

/* close connection */
mysqli_close($link);
?>
