Question

How do I use a variable entered in a text box to be the search for the TinySong api? I tried using some variables but to no avail. Here is what I tried:

<?php
if(isset($_POST['submit'])) {
 echo ' ',  htmlspecialchars($_POST['something']);
}
?>

<?php


require_once 'tinysong.php';

$api_key = 'MY API KEY';

$query = '$something ';


$tinysong = new Tinysong($api_key);


$result = $tinysong
            ->search($query)
            ->execute();


echo "<pre>";
print_r($result);
echo "</pre>";
?>

I don’t understand why the text box’s value isn’t being queried. What do i have to change for it to work?? Thank You

You have no variable $something. You have $_POST['something'], but unless register_globals is on (which it shouldn’t be), you never populated $something. You therefore have nothing to query.

$query = $_POST['something'];

Incidentally, you’ve also used single quotes here, which won’t cause the variable to be interpolated. Double quotes are needed for interpolation:

// This would have needed double quotes if it wasn't incorrect anyway...
$query = '$something ';

$query = "$something ";
