The Bat

Using your code, the 'Loading..' text appears and disappears very quickly between showing 'not found', but doesn't show anything while loading the image. Why is this?

Hello, I am just recently getting into Ajax, and I am wondering how to add a loading status to my script. I tried adding: if (xmlhttp.readystate == 3) { document.getElementById('ok').innerHTML = 'Loading...'; } to my ajax.html page in the script below, but it did not show up when ajax.html was loading a big image. Here is my Ajax script and PHP script: ajax.html <script type="text/javascript"> function ajax() { var xmlhttp; if (window.ActiveXObject) { xmlhttp = new ActiveXObject('Microsoft.XMLHTTP'); } else { xmlhttp = new XMLHttpRequest(); } xmlhttp.onreadystatechange = function() { if (xmlhttp.readystate == 3) { document.getElementById('ok').innerHTML = 'Loading...'; } if (xmlhttp.readyState == 4) { document.getElementById('ok').innerHTML = xmlhttp.responseText; } } xmlhttp.open('GET', 'ajax.php?q='+document.myForm.name.value, true); xmlhttp.send(null); } </script> <form name="myForm"> Name: <input type="text" name="name" onkeyup="ajax()" /> </form><p> <div id="ok"></div> ajax.php <?php $userQuery = mysql_query("SELECT username FROM users WHERE username='".$_GET['q']."'"); if ($_GET['q']) { if (mysql_num_rows($userQuery) > 0) { // Trying to show 'Loading...' when loading a big image. echo '<img src="bigimageURL">'; } else { echo '<font color="red">not found.</font>'; } } ?> Thank you for your help!

Take a look at PHP's shuffle() function.

To give you a rough outline of what you can do, first you can create a field in the specified table called 'allow_free_mp3' (or whatever you want) and on myaudio.php, have a form with 'yes' or 'no' options and have that inserted into the field: myaudio.php <form action="myaudio.php" method="post"> Allow free MP3s to be downloaded? <select name="allowfree"> <option value="yes">Yes</option> <option value="no">No</option> </select> <input name="update" type="submit" value="Update" /> </form> <?php if ($_POST['update']) { // Connect to your database. mysql_query('INSERT INTO table_name (allow_free_mp3) VALUES ('.$_POST['allowfree'].')') or die (mysql_error()); } ?> listen.php <?php $allowquery = mysql_query('SELECT allow_free_mp3 FROM table_name /* Specify WHERE options */'); $row = mysql_fetch_array($allowquery); if ($row['allow_free_mp3'] == 'yes') { // Your code when free MP3 downloading is allowed. } else { // Your code when free MP3 downloading is NOT allowed. } ?> It isn't that great, but it's a start. If you want to know about using MySQL with PHP, just searh Google.

Say what? You can, using the 'time()-[specified seconds]' parameter in the setcookie() function.

You could also possibly use $_GET. Link: <a href="yourpage.php?changevar=true">Change the variable!</a> Code on yourpage.php: $i = 1; if ($_GET['changevar'] == true) { $i = 2; // Other actions... }

Is this what you want? - if (eregi("^www\.[a-z0-9_\-]+\.[a-z0-9_\-\.]+$", $url)) { // Code when accepted... } else { // Code when denied... }
