    what you will need to be thinking about is caching. I would suggest having a method of finding out when the tables were last updated, maybe an auto field in mysql with a timestamp. You will then query the data and store it, somehow, that's for you to decide what's best. Next time you run the same query, check the timestamp, if no updates since query was last run then use the cached results. If I were you i'd look at creating the array as you suggest, then serialize it, http://php.net/manual/en/function.serialize.php If you need more help with anything then don't hesitate to ask as I'm a team leader on a project that is estimated to have over 1 million active users within the next 6 months and so I've had to become an expert on stuff like this, scalability, very quickly.

    short answer, no, not if you're wanting to display ALL topics on 1 page. however, I would suggest getting rid of the cache file and paginating instead, that way you wont have a cache file that's hours otu of date, you'll have a constantly up to date connection to your DB.

    change to <body> <table width="70%" align="center"> <tr> <td> <h1>My Web Page</h1> </td> </tr> </table> <table width='70%' align="center"> <tr> <td width="13%" valign="top" align="left"> <b> <a href="index1.php?page=home">Home</a><br> <a href="index1.php?page=tutorials">Tutorials</a> </b> </td> <td width="87%" align="left"> <?php if(isset($_GET["page"])) { $page = $_GET["page"]; include($page.".php"); } else { include("home.php"); } ?> </td> </tr> </table> </body>

    Well if you're setting visible to yes then you will get that error as you've spelt it wrong.... You've spelt it as visbile... Change your code to: <?php require_once("includes/connection.php"); ?> <?php require_once("includes/functions.php"); ?> <?php find_selected_page(); ?> <?php include("includes/header.php"); ?> <table id="structure"> <tr> <td id="navigation"> <?php echo navigation($sel_subject, $sel_page); ?> </td> <td id="page"> <h2>Add Subject</h2> <form action="create_subject.php" method="post"> <p>Subject name: <input type="text" name="menu_name" value="" id="menu_name" /> </p> <p>postion: <select name="position"> <?php $subject_set = get_all_subjects(); $subject_count = mysql_num_rows($subject_set); //$subject_count + 1 because we are adding a subject for($count=1; $count <= $subject_count+1; $count++) { echo "<option value=\"{$count}\">{$count}</option>"; } ?> </select> </p> <p>Visible: <input type="radio" name="visible" value="0" /> No <input type="radio" name="visible" value="1" /> Yes </p> <input type="submit" value="Add subject" /> </form> <br /> <a href="content.php">Cancel</a> </td> </tr> </table> <?php require("includes/footer.php"); ?>

    no, no if it is across servers as the unserialized object MUST have direct access to the classes it was derived from.
  6. GKWelding
    Sorry, I should expand on ym first point, to have access to the methods again you need to un-serialize the object!
  7. GKWelding
    As long as the unserialized object still has access to the class it was derived from you will have access to the methods associated with that object. The point of serialisation is, in the context I've used it in before, for caching large objects that do not change much over time. Please be aware however, that de-serialization is very slow. Check out the article below for some interesting stuff with objects and serialization. http://www.devshed.com/c/a/PHP/The-Basics-of-Serializing-Objects-in-PHP/1/

    do print_r on all 4 variables within the IF statement, make sure they are what you are expecting. if not then that's your problem.
  9. GKWelding
    ok, now change the following section to: $username = trim($array[0]); //user-name $password = trim($array[1]); //password print_r($username); print_r($password); and check that matches what you're typing in to login.
  10. GKWelding
    ok, do me a favour, change to the following: $fp = fopen("registrationinfo/info.txt","a+"); $fileData = fread($fp,filesize("registrationinfo/info.txt")); print_r($fileData); fclose($fp); You will get the headers error again but ignore that and paste the printed data to this thread.
  11. GKWelding
    however, the headers error is because you're trying to modify header info after an error has been output to the screen. fix the error and the headers error will go.
  12. GKWelding
    dammit, my fauly, fclose($file); should be fclose($fp); and read the post stickied at the top of this form for headers already sent.

    if it is database driven and you want to search for info in the database then try this article. http://onlamp.com/pub/a/php/2002/10/24/simplesearchengine.html?page=1
  14. GKWelding
    more details on your website needed. is it database driven? what are you lookign to search for?
  15. GKWelding
    Try the following. <script type="text/javascript"> function requestforbreak(id,name) { requestbreak(id,name); empid=id; interval = window.setInterval("checkforbreaks();",1000); } function requestbreak(id,name){ http.open('get', '../../queuecenter/include/requestBreak.php?empID='+id+'&agentName='+name); http.onreadystatechange = function(){ if(http.readyState == 4){ var response = http.responseText; document.getElementById('breakreqmsg').innerHTML = ' ' +response+ ''; } } http.send(null); } function checkforbreaks(){ http.open('get', '../../queuecenter/include/breakPending.php?empID='+empid); http.onreadystatechange = function(){ if(http.readyState == 4){ var response = http.responseText; if(response == 'false'){ window.clearInterval(interval); document.getElementById('breakreqmsg').innerHTML ='Done'; } document.getElementById('breakreqmsg').innerHTML = ' ' +response+ ''; } } http.send(null); } </script>

    Honestly, you can put the JS wherever you like when you're incluyding it in that way (which is also the way I include it in my CI applications), there is no right or wrong way of including jQuery into CI. however, I'm not quite sure what your problem is, are you getting an incorrect value back after the calculation?
  17. GKWelding
    also, can I point out that because you're using a file with the extension .txt if somebody gueses the location and name of this file then they will be able to see all of your usernames/password in their browser in plain text, not very secure at all. you'll need a htaccess file in the same directory with the following in it (Google htaccess): IndexIgnore *.txt

    $fp = fopen("registrationinfo/info.txt","a+"); $fileData = fread($fp,filesize("registrationinfo/info.txt")); fclose($file); $array = explode(':', $fileData); mode a means wrtie only, a+ means read/write.

    You'll want to use the PHP cURL library... http://uk2.php.net/manual/en/ref.curl.php You'll need to use the curl_setopt (http://uk2.php.net/manual/en/function.curl-setopt.php) function after curl_init to allow it to use cookie sessions.

    no separate form needed, just follow the work around and you'll see.

    Ross, With regards to point 1, both the first two points are perfectly acceptable. However, for ease and the fact it's much more flexible, I would bypass the controller and call the model directly returning an array of data to do what you like with. Secondly, I would go down the route of processing ajax requests differently, as if you process them the same then you'll be loading the framework every time when you really don't need to. I hope some of this helps.
  23. GKWelding
    to be honest I'd recommend using jQuery to achieve this! It would be as simple as: var filename = jQuery('#image1').val(); jQuery.post('imagedelete.php', { filename: filename }); You imagedelete.php file would need to be looking for $_POST['filename'], but this is easily changeable...

    see if this sheds some light on it... http://www.phpfreaks.com/forums/index.php/topic,271957.0.html

    you cannot uppload files via AJAX, sorry, you have to do a little work around using an iframe. linked below. http://geekswithblogs.net/rashid/archive/2007/08/01/Create-An-Ajax-Style-File-Upload.aspx
