Building Web Forms In Flash
Collect user data on your Web site with Flash-based forms.

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:

<head><basefont face="Arial"></head>

<h2>Search Results</h2>

// 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


Here's what the search box looks like,
