This image refreshes every three hours, starting with 0 and then 3,6,9,12.....21 in a 24 hour calendar, and are stored for days in advance. The date/time is in the file name. Originally I had written the script to refresh on the hour, and then realized the tri-hourly spacing. This is what I have: Code: [Select] <?php date_default_timezone_set('Etc/GMT-1'); $today = date("YmdH"); $pattern = '/WaveHeight_'.$today.'_mic.png'; $base_url = 'http://www.crh.noaa.gov/images/greatlakes/ndfd/MIC/dynamic2'; print '<a href="http://www.crh.noaa.gov/greatlakes/?c=map&l=lm&p=a"><img src="'.$base_url.$pattern.'" width= "237" hieght= "314" " ></a>'; ?> I am not fluent in php, but I assume I need a "If H=1,4,7,10,13,16,19,22; Then H+2 ; along with If H=2,5,8,11,14,17,20,23; Then H+1" to keep the images relatively current. I just can't quite wrap my head around how to express this. Any help is appreciated. Thank you. please this code is not working,i want when users comment on a page it should refresh this is my code: Code: [Select] <h3>Comments:</h3> <table> <tr class="row-a"> <td class="first"></td> <td><?php include"header.php"; $sql="SELECT post_content,post_by FROM post ORDER BY topicsID"; $result=mysql_query($sql)or die(mysql_error()); while($row=mysql_fetch_array($result)) { echo"<strong>{$row['post_by']}</strong>: {$row['post_content']}"."</br>"; } if(mysql_affected_rows()>0) { header("location:".$_SERVER['PHP_SELF']); } ?></td> </tr> </table> <h3>Post your comments here</h3> <form action='reply.php'method='post'> <textarea name="comment" id="content" style="width:400px;height:50px;background-color:#D0F18F;color:#000000;font:15px/20px cursive;scrollbar-base-color:#638E0D;"></textarea> <br /> Name:<input type="text"name="name"/> <input class="button" type="submit"name="submit"value="submit" /> </p> </form> <br /> [code] Hi!!! i created this code for my chatroom!!

Hi all, Thanks for reading. I'm running a script using jQuery that auto-refreshes a <div> on the index page from an external PHP script to get all the rows in a database and display them on the index page. The script works great - here it is as follows: Code: [Select] <script type="text/javascript"> $(document).ready(function() { $("#responsecontainer").fadeOut("fast").load("getrows.php").fadeIn("slow"); var refreshId = setInterval(function() { $("#responsecontainer").fadeOut("fast").load('getrows.php').fadeIn("slow"); }, 5000); $.ajaxSetup({ cache: false }); }); </script> The getrows.php script I'm working with looks like this: Code: [Select] <?php $rowsQuery = mysql_query("SELECT * FROM Happenings WHERE HappeningDate='$today'"); if (mysql_num_rows($rowsQuery) == 0) { $happeningsToday = "There are no happenings today."; } else { $allHappeningsToday = 1; while ($getHappeningsToday = mysql_fetch_array($rowsQuery)) { $happeningName = stripslashes($getHappeningsToday['HappeningName']); $happeningDate = $getHappeningsToday['HappeningDate']; $happeningDescription = $getHappeningsToday['HappeningDescription']; if ($allHappeningsToday == 1) { $happeningsToday .= " <div class=\"box\"> <p>".$happeningName." | ".$happeningDate." | ".$happeningDescription." </div>"; $allHappeningsToday = 2; } else { $happeningsToday .= " <div class=\"box\"> <p>".$happeningName." | ".$happeningDate." | ".$happeningDescription." </div>"; $allHappeningsToday = 1; } } } echo $happeningsToday; ?> This script works great as well. Currently, the auto-refresh jQuery script as you can see if getting and fading in/out all of the rows. Off of the above getrows.php script, is there a way after I could get only the newly created rows since the last refresh and only fade those in and out while leaving the others already loaded by the auto-refresh script to not fade in/out? Any ideas, thoughts or suggestions would be unbelievably helpful. Thank you very much. will refresh a page every second will cause some crash or error ?? cause when i try this, it sometimes display this error "Warning: mysql_connect() [function.mysql-connect]: Can't connect to MySQL " this is occur when i run it in my local server. I am so worried if this might also happen when i run it online. thanks So basically, My Bulletfactory page is playing up. Every 30 minutes the bulletfactory should produce bullets, it is producing the bullets fine, but only when someone views the page (after 30 minutes is up). If there any kind of PHP refresh for this? Or do i just use normal refresh? Thanks Hello i want make a button in one page for example button.php to refresh other page for example screen.php is there a way to auto refresh the same page youre on after a script runs? hello, i have a page that parses a string from espn and i have a style sheet that makes it refresh every 2 minutes. the thing that is buggin me is that when i load the page it loades with the last cached data so i have to wait 2 minutes for the info to update. is there any way to force the current content on load, and keep my refresh every 2 minutes still? thanks I've been doing some searching, but I can't figure this out, as I don't know enough about JS.

But I don't know what exactly I can remove, what needs to stay (as far as the js), and where exactly I insert my ad code that is in a <script> tag of its own... but that also has a <noscript> tag as a fallback. While I understand I need to change the refresh from 3 secs, can someone help me take out the example JS code, and tell me where I would put my JS ad code? And do I simply remove the <script tags from my ad code, when inserting it into an area that is already between <script> tags?
Any help on this would be appreciated, thanks!
i have already echoed title and included that file in my php script, a header file.... but now i want to refresh my php script if the comment has been successfully added else remain in the same page....it remains in the same page now with just a msg that the comment is added....but i cant see the comment unless i refresh the page... i get he headers already sent error when i put a header() there as i have included another php file which already echoes title to screen....so what do i do now? i want the comment to be displayed to the user once he clicks on save and not make it tedious for him to refresh....any suggestions?any way around? I have a php page that is maid up of three pieces. header.php main.php footer.php I can't figure out how to refresh the header.php and footer.php without refreshing the main.php. Anyone have an example of how I can do this. Thanks hits i have set up a search form which is linked to dynamic update form on the same page, when you pick an item from listbox in form 1 it will populate form2 (update form) with the data from DB and repeat for all matching records, the update of the form is done by using a checkbox (onclick), all this works fine and DB updates fine. My problem is when i check a checkbox in any of the update forms the data is updated but all the update forms are removed so if i want to update another record i need to enter original search again to get forms to display again i know the problem is because the page is refreshing when onclick is activated and it loses the search value so returns empty form. i know you can use java to stop page refreshing but never used it before and been trying to get it to work with no success, is there any other way to keep page from refreshing After I submit form data how can I force the page to refresh so I can see the changes take effect? I know this is probably a very basic question. I'm having trouble getting my script to refresh the page. If the username, password match it falls into this if statement. Sometimes it works and other times and won't refresh the page automatically. I'm trying to use this line to refresh the page Code: [Select] echo "<meta http-equiv='refresh' content='=2;index.php' />"; Here is the if statement Code: [Select] if(mysql_num_rows($checklogin) == 1) { // store the row returned from query $row = mysql_fetch_array($checklogin); // get email address from row returned $email = $row['EmailAddress']; // store user variables in session array $_SESSION['Username'] = $username; $_SESSION['EmailAddress'] = $email; $_SESSION['LoggedIn'] = 1; // boolean echo "<h1>Success</h1>"; echo "<p>We are now redirecting you to the member area.</p>"; echo "<meta http-equiv='refresh' content='=2;index.php' />"; } here is the entire index.php file Code: [Select] <?php include "base.php";?> <!-- base.php contains session_start() --> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>User Management System (Tom Cameron for NetTuts)</title> <link rel="stylesheet" href="style.css" type="text/css" /> </head> <body> <div id="main"> <?php // check if user is already logged in if(!empty($_SESSION['LoggedIn']) && !empty($_SESSION['Username'])) { ?> <h1>Pitch Shark Member Area</h1> <p>Thanks for logging in!

Basically the code is set for a Factory to produce 750 items every 30 minutes. It does this fine IF AND ONLY IF someone clicks the Factory page. For example, it produces 750 bullets, then I leave the page alone for say 20 minutes, but when I click back, it doesn't have 10 minutes left before the next produce. Instead, It has 30 minutes. So it only produces when someone on the game clicks the page. I have tried the basic html refresh but that doesn't work. Any idea's? Thanks in advance Hi All, I was wondering if there is any way that a PHP page can update itself when a row in a DB is added or updated? I am trying to get a feed up and running and want it to update when a row is updated/inserted. Thanks Matt |
