Here's what I have so far. <?php $magicLevel = $_POST['magicLevel']; $playerLevel = $_POST['playerLevel']; $rune = $_POST['rune']; //gets the value "lmm" $maxDamage = 0; switch($rune) { case "lmm": $maxDamage = ($playerLevel*0.2)+($magicLevel*0.81)+4; break; } echo $maxDamage; ?> What I need to round down is this part: ($playerLevel*0.2) Thanks in advance! I need to take a time and convert so it is rounded up or down to the nearest 0 or 5. Code: [Select] function roundMe ($time, $upDown) { if($upDown==1) { //round up } else { //round down } return $x; } echo roundMe("16:22", 1); // returns 16:25 echo roundMe("16:22", 0); // returns 16:20 echo roundMe("16:25", 1); // returns 16:25 echo roundMe("16:59", 1); // returns 17:00 echo roundMe("16:59", 0); // returns 16:55 How can I order this query of zip codes within the radius by nearest?

Let me give Data Again: Quote $html = '<img src="some_source" title="paintball mask Picture" alt="Image for Paintball Mask"> <strong> Best Paintball Mask</strong>'; Find What: Paintball Mask Find in Which Tag: <strong> </strong> Replace it with: <a href="/">Paintball Mask</a> can someone help me with the code? Cheers Natasha Thomas Hi guys I am new here I have had a search around and can't really find out how to do this. Its quite difficult for me to explain and I am really new to PHP / mySQL - just starting out really. I hope to learn from doing small projects like this and seeing how it gets done. So I have a mySQL DB with two different tables - one is called "notesnew" the other is called "users". I have modified a common tutorial on how to make a "to do list" for what I am doing here. Basically users can login and post messages on this list as them self. Each user's post appears as a list item, showing their username, the time they posted the message and the message content. The message content, time and owner of the message is stored in the "notesnew" table. The list of user's, their passwords and their "avatar/profile" image URL location is stored in the "users" table. Now I am having trouble getting each user's avatar image from being output next to each of their posts. The part that is confusing me is being able to match up the username's post with their content that is display - because I am posting the user's name along with their post, based on the logged in "session name" as their username. So basically, all the content being listed is being displayed from the "notesnew" table. I need to somehow figure out what each user's profile image is based on what is stored against their entry in the "users" table. Here is the code I have so far. It is not working properly - it displays all content etc, but displays the avatar / image of the last user that has registered. Can anyone help me out here with some code that works, or pointers to try follow? I know the $finduserprofile part is incorrect in the way it goes through all user's and finds their profileimg, and that the image displayed next to each post is therefore incorrect (as it displays the last member to have registered's avatar, but its just that I don't know how else to do what I am trying to do. Code: [Select] <?php //Connect to the database $connection = mysql_connect('localhost', 'zzzz' , 'zzzzzzz'); $selection = mysql_select_db('zzzzz', $connection); $username = $_COOKIE['ID_my_site']; //Was the form submitted? if($_POST['submit']){ //Map the content that was sent by the form a variable. Not necessary but it keeps things tidy. $content = $_POST['content']; //Insert the content into database $ins = mysql_query("INSERT INTO `notesnew` (content, owner, dp_time) VALUES ('$content', '$username', NOW())"); //Redirect the user back to the members or index page header("Location:index.php"); } /*Doesn't matter if the form has been posted or not, show the latest posts*/ //Find all the notes in the database and order them in a descending order (latest post first). $find = mysql_query("SELECT * FROM `notesnew` ORDER BY id DESC"); $finduserprofile = mysql_query("SELECT * FROM `users` ORDER BY id DESC"); //Setup the un-ordered list echo '<ul>'; while($row = mysql_fetch_array($finduserprofile)) { $imagelocation = $row['profileimg']; //Continue looping through all of them while($row = mysql_fetch_array($find)) { $owner = $row['owner']; //For each one, echo a list item giving a link to the delete page with it's id. echo '<li>' . '<img src ="' . $imagelocation . '">' . $row['owner'] . ' said at ' . $row['dp_time'] . ': ' . $row['content'] . ' <a id="' . $row['id'] . '" href="delete.php?id=' . $row['id'] . '"><img src="delete.png" alt="Delete?" /></a></li>'; } } //End the un-ordered list echo '</ul>'; ?> this is my first post so I hope someone can help find a solution to this problem. I created this website in wordpress www.porthopehealthcentre.com It displayed correct in firefox but not ie. There was an extra closing </div> tag in my header php. I deleted this and now it displays correct in ie but not firefox. Can I somehow link to two different header files one for ie and one for firefox? if so how do I do this? Or is there an easier solution to this. I would really appreciate someones help as this is the final thing that needs adjusting to finish the job. Hi, Im building a management web application that can contain sensitive information for people, allow for cheques to be printed, amoung other things. Im wondering what are some extra security features that could be added as some users may not want to have the web application available outside their business. I would preffer doing this without having to run the server locatlly on thier machine. i was thinking something like only allowing certain ip address's to access the sites login. Anyone have any other/better ideas? For some reason this only allows one SQL to be added... // SQL Connection $username="monstert_admin"; $password="admin"; $database="monstert_admin"; $connection = mysql_connect("localhost", $username, $password) or die("Connection Failure to Database"); // Select Database mysql_select_db($database, $connection) or die ($database . "No Database" . $username); //Select everything from the the table $MyQuery = "SELECT * FROM photos"; $retrieve = mysql_query($MyQuery) or die(mysql_error()); if(mysql_num_rows($retrieve) != 0): $row = mysql_fetch_assoc($retrieve); else: echo ''; endif; if(isset($_POST['Submit']) && !$errors) { $url = $newname; include('img.php'); $image = new SimpleImage(); $image->load($url); $image->resize(500,315); $image->save($newname); mysql_query("INSERT INTO photos (url) VALUES ('$url')"); echo "File Uploaded Successfully as <i> "; echo $newname; echo "</i>"; } What would the issue be? I only have two columns - ID and url Thanks in advance! I have a form that has this: Code: [Select] <input type="text" name="notes_date" size="10" value="<?php echo date("m/d/Y");?>" /> I enter into the database after processing the variable like this: Code: [Select] $notes_date=date ("Y-m-d H:i:s", strtotime($_POST['notes_date'])); However, it gets stored at 2012-03-15 00:00:00 How do I fix this so that the current time gets stored instead of 00:00:00? So I ran into the most bizarre problem ever on my live server. For some odd reason something, somewhere is adding an extra character after every " mark I have. Now I am using zend framework but this can not be an issue involving them since everything works perfectly on my localhost. I am using 1and1 to host my application but for the love of me I can not narrow this down any more. Ex of my problem, I type this into my text box: "This is a sentence" and it proceeds to saving this: \"This is a sentence\" Something is happening right after I submit my form because if I add the code directly in my database, it displays everything fine. Has any one ever ran into this problem before? I hope that subject made sense! I have a page where I want to generate page-specific keywords automatically. Actually I have some general keywords stored in a text file and then I add the page-specific ones after those. The problem is, however, solely caused by the keywords I pull from my text file. A "1" is added to my list of keywords. Consider a news page like so: news.php // ... <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta name="keywords" content="<?php require('php/generateKeywordList.php'); ?>" /> </head> // ... And then generateKeywordList.php // I have omitted the part with the page-specific keywords, because it is not what causes the problem (commented it all out) set_include_path('/mypath/'); $str = require_once('includes/websiteKeywords.txt'); echo $str; // For some reason, the number 1 is added at the end of this string websiteKeywords.txt (it doesn't matter what I put in there) Code: [Select] these, are, my, keywords, for, my, website In my meta tag, the above would be displayed as: Code: [Select] these, are, my, keywords, for, my, website1 I then tried to make a simple php page like this $keywords = require('includes/websiteKeywords.txt'); echo $keywords; ... and it worked. At the moment I have absolutely no idea where the number 1 comes from. So, basically if I include the keywords directly from the text file into my meta tag, it displays fine. If I make a simple php page where I echo out the keywords from the text file, it displays fine. But if I include my php script, which echos the keywords, into my meta tag, the number 1 is added at the end of the string. Am I completely missing something here or is this extremely strange? Thanks for any help! The script below used to work fine but the HTTP_REFERER was unreliable so i added a re-direct if the HTTP_REFERER was unavailable and now nothing is being added to the MySQL BD, the script runs ok ie it sends the user back to where they come from, any ideas what could be wrong? <?php require("../include/mysqldb.php"); $uinwish = $_GET['uinwish']; $wishrefer = $_SERVER['HTTP_REFERER']; $wishdate = mktime(0, 0, 0, date("m"), date("d")+3, date("Y")); $rand_wish_cookie = $_COOKIE["wishtracking"]; $con = mysql_connect("$dbhost","$dbuser","$dbpass"); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("$dbame", $con); //DB Stuff start code below //check if the uin and cookie have already been stored together. $sql = "select * from Wish_list_guest where usercookie='$rand_wish_cookie' and uinwish='$uinwish'"; $result = mysql_query($sql); $row = mysql_fetch_row($result); if (mysql_num_rows($result)!= 1) { $issetvar = "1"; if (!isset ($wishrefer)){ $host = $_SERVER['HTTP_HOST']; $extra = 'profile.php?uin='; header("Location: http://$host/$extra$uinwish"); exit; } if (isset ($wishrefer)){ header("Location: $wishrefer"); exit; } } if ($issetvar = 1) { mysql_query("INSERT INTO Wish_list_guest (usercookie, date_delete, uinwish, referwish) VALUES ('$rand_wish_cookie', '$wishdate', '$uinwish', '$wishrefer')"); mysql_close($con); if (!isset ($wishrefer)){ $host = $_SERVER['HTTP_HOST']; $extra = 'profile.php?uin='; header("Location: http://$host/$extra$uinwish"); exit; } if (isset ($wishrefer)){ header("Location: $wishrefer"); exit; } } ?> I have a membership site that a user creates a username and password at registration. The user logs in and all that works. The usersname is located in the database under users. Each page is protected and you must login to access it. Here is the code for that
checkLogin('2');
$getuser = getUserRecords($_SESSION['user_id']);
If the user login is correct they have access to the page. This all works fine as I said. On this page is a form that gets filled out. All the data except the username is added to the database for the contents of this form. I need to have the username added to the database to track who the data belongs to. Here is the code I have for this, can some tell me where I messed up.
The line under the the code <body> pulls the username and the echo command prints the username on the page. I repeated this code under the
if ($_SERVER['REQUEST_METHOD'] == "POST") code and it also prints the username.
<?php
// this is processed when the form is submitted
// back on to this page (POST METHOD)
if ($_SERVER['REQUEST_METHOD'] == "POST")
{ $usernow = $getuser[0]['username'];
$userid = $usernow;
echo "$userid";
# escape data and set variables
$userid = addslashes($_POST["userid"]);
$date = addslashes($_POST["date"]);
$temperature = addslashes($_POST["temperature"]);
$ph = addslashes($_POST["ph"]);
$ammonia = addslashes($_POST["ammonia"]);
$nitrite = addslashes($_POST["nitrite"]);
$nitrate = addslashes($_POST["nitrate"]);
$phosphate = addslashes($_POST["phosphate"]);
$gh = addslashes($_POST["gh"]);
$kh = addslashes($_POST["kh"]);

$sql .= " (id, userid, date, temperature, ph, ammonia, nitrite, nitrate, phosphate, gh, kh, iron, potassium, notes) VALUES ";
$sql .= " ('', '$userid', '$date', '$temperature', '$ph', '$ammonia', '$nitrite', '$nitrate', '$phosphate', '$gh', '$kh', '$iron', '$potassium', '$notes') ";
