Building Web Forms In Flash - Access Granted
(Page 2 of 6 )
Obviously, that was a very primitive example, though one that did demonstrate the concept of integrating user-supplied data with a server-side script via a Flash movie. Now, how about a twist?
This next example uses the data entered into a Flash form to query a database and return a list of matches. In order to create the form, create a new Button symbol, in much the same way as you created the one on the previous page. Name the form variable within the symbol "q", and add a copy of the instance to the Flash movie.
Once that's done, add some ActionScript to the symbol instance, referencing the server-side script "search.php" - this time, use POST to send the form variables to the script.
on (keyPress "<Enter>") {
getURL ("search.php", "", "POST");
}
All that's left now is to write the PHP script "search.php".
Here's what mine looks like:
<html>
<head><basefont face="Arial"></head>
<body>
<h2>Search Results</h2>
<ol>
<?
// search.php
// get query term
$query = trim($_POST['q']);
// open connection to database
$connection = mysql_connect("localhost", "user", "pass") or die ("Unable
to connect!");
mysql_select_db("db20139a") or die ("Unable to select database!");
// formulate and execute query
$query = "SELECT * FROM data WHERE tag LIKE '%$query%' OR keyword LIKE
'%$query%'"; $result = mysql_query($query) or die("Error in query: " .
mysql_error());
// get record
while($row = mysql_fetch_object($result))
{
echo "<li>";
echo "<a href=go.php?id=$row->id>$row->tag</a>";
echo "<br>$row->title";
echo "<p>";
}
// clean up
mysql_close($connection);
?>
</ol>
</body>
</html>
Here's what the search box looks like,
and here's a sample results page.
