Question

I’m trying to extract the MAX streamitem_id from the streamdata table but when I change the query from SELECT streamitem_id to SELECT MAX(streamitem_id) it gives me the below error.

How can I rectify this issue?

This is the error I’m getting from Firebug.

 SyntaxError: unterminated string literal
    [Break On This Error]   

    var current_last_status_id="<br />

An below the client side code

<?  $timestamp = "SELECT MAX(streamitem_id) FROM streamdata";
            $chant = mysqli_query($mysqli, $timestamp) or die(mysqli_error($mysqli));
            while ($streamitem_data= mysqli_fetch_array($chant)) {

    ?>
    <script>


    setInterval(function(){
        var current_last_status_id="<?php echo $streamitem_data["streamitem_id"];?>";

           $.ajax({ type: "GET", 
                    url: "streampostinsert.php?current_last_status_id=" + current_last_status_id,  

                    dataType:"json",
                    cache:false,
                    success: function(response){

Try changing the SQL to this

$timestamp = "SELECT MAX(streamitem_id) AS streamitem_id FROM streamdata";

The error you are seeing in firefox is a javascript error, but I think the real error is that PHP is throwing a notice about undefined index streamitem_id in the middle of your javascript.

I believe you need to alias the returned value or you will have something along the lines of..

$streamitem_data['MAX(streamitem_id)']

Which is a nightmare
