Testing to see if a string ends in .gif

[jimmyelewis]

Hey,

I have the following code
[code]
if (mysql_query ($query)) {
    echo 'The tool has been added.';
    } else {
    echo '<p>Could not add the tool because <b>' . mysql_error() . '</b>.  The query was ' .$query . '.</p>';
    }
    mysql_close();
}
// Display form
?>

<form action="index.php" method="post">
<p>Tool Name: <input type="text" name="tool_name" size="40" maxsize="50" /></p>
<p>Tool Icon Name: <input type="text" name="tool_icon" size="40" maxsize="50" /></p>
<p>Tool Link: <input type="text" name="tool_link" size="40" maxsize="150" /></p>
<p>Tool Category:
    <select name="tool_cat">
    <option value="Inventory">Inventory</option>
    <option value="Network Tools">Network Tools</option>
    <option value="Reference">Reference</option>
    <option value="User Account Tools">User Account Tools</option>
    <option value="Web Tools">Web Tools</option>
    </select></p>
<input type="submit" name="submit" value="Add Tool" />
</form>
[/code]

If I wanted to check to see that tool_icon ends with .gif how would I do that and if it doesn't end in .gif where would I echo to the use to please end tool icon name with .gif.

Yes, because it adds the icon name to a mysql database.

if (pregi_match(".gif$", $_POST['tool_icon'])){
$ok=TRUE;
