PHP - Make Session Invisible
Hi,
So, I have two sessions. One's for displaying an array. Is there some kind of function to make a session invisible? Because when I display an error for not filling in, the previous words of the array show up behind the error message. Like this: $error = 'Please enter a word.' Output: Please enter a word.word word word So is there a way to make my Session Invisible (not removing any words from array)? Similar TutorialsHi all . I have a button now when i click the button an mypages is valid can i make that button in the page invisible in postback with php?? I know you can in C# by saying button1.Visible = false; Thanks for input... $result = mysqli_query($con,"SELECT * FROM $_SESSION['datakey']"; Hello all, I've made this for users login, and now I want the user to only be able to see his info so how can I use the $_SESSION['userid'] to search the database for it's value and echo results? here is my code, I want to use the session value instead of get Code: [Select] <? if (isset($_GET['id'])) { $con = mysql_connect("supremecenter14.co.uk","teko_waw","tmisabro77"); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("teko_waw", $con); $result = mysql_query("select * from users where id = '{$_GET['id']}'"); $row = @mysql_fetch_array($result); echo "<table width=98%>"; echo "<tr>"; echo "<td valign=\"top\" width=\"120px\">"; $rowid = $row['id']; echo "<td valign=\"top\">"; echo "<table> <tr> <td valign=\"top\" class=\"searchtitle\"> ".$row['fname'].

Note i have no ability to change phpconfig. Hi, How to create an invisible text in an image. Any idea? Thanks. Hello ive Googled around for ages for a PHP script that Shows the yahoo user statuts .. but the only thing i ve found is this link from yahoo thats saying the Online/Offline statuts http://opi.yahoo.com/online?u= ive heared that theres some way of sending a bot to the id and see if its on invisible .. dos anyone know a way to do it ? I am having trouble resolving an error.

I have tried to replace the header (Location: 'admin.php') with this: echo "<script>document.location.href='admin.php'</script>"; echo "<script>'Content-type: application/octet-stream'</script>"; I've been trying to read up on solutions but haven't been able to get it sorted. If anyone can offer some advice that would be greatly appreciated as im new to php.

Any hints on how i should accomplish this? Code: [Select] session_start(); $_SESSION['ID']=$_GET['ID']; // id from previous page $ID=session_id(); <iframe src="iframepage.php?ID=<?php echo $ID; ?>" style="width:680px; height:200px;" noresize="noresize" frameborder="0" border="0" scrolling="Yes" allowtransparency="true" /> </iframe> I'm making a simple login system with MySQL and PHP (very simple, I'm just starting with PHP). The MySQL portion is done, but I need to ensure only people who are logged in can see certain content. To check if people are logged in, my website checks that they have the $_SESSION['user'] variable set. If it is set, then it lets them continue through the website, if not, it tells them to login. Is that enough security, or can people simply inject a session cookie into their browser to spoof that they are logged in? My idea was to generate a session key cookie when they login (just a random string of letters and numbers) and store that in the database, then on every page, check to make sure their session key is the same thing that's in the database. Is this necessary? It seems expensive. Just curious how other people feel about this. I am working on an application where a lot of info is pulled from MySQL and needed on multiple pages.
Would it make more sense to...
1. Pull all data ONCE and store it in SESSION variables to use on other pages
2. Pull the data from the database on each new page that needs it
I assume the preferred method is #1, but maybe there is some downside to using SESSION variables "too much"?
Side question that's kind of related: As far as URLs, is it preferable to have data stored in them (i.e. domain.com/somepage.php?somedata=something&otherdata=thisdata) or use SESSION variables to store that data so the URLs can stay general/clean (i.e. domain.com/somepage.php)?
Both are probably loaded questions but any possible insight would be appreciated.
Thanks!

Edited by galvin, 04 November 2014 - 10:30 AM. Evening! I've been iffing and ahhing over this and well im not too sure, hence the post. Code: [Select] // Redirects if there is no session id selected and echos the error on the previous page if(!isset($_GET['get']) || ($_GET['getget'])){ header("Location: #.php?error"); } So it should simply check if get is set if it isnt then see if getget is set? If not redirect and show the error. Now ive tried it and even when get/getget is set it still redirects, probably something silly. Care to share anyone? Harry. Okay so my news script is set to view only 10 pieces of news. But I want it so that it starts a new page once I have more than 10 pieces of news. Code: [Select] <?php require("functions.php"); include("dbconnect.php"); session_start(); head1(); body1(); new_temp(); sotw(); navbar(); $start = 0; $display = 10; $query = "SELECT * FROM news ORDER BY id DESC LIMIT $start, $display"; $result = mysql_query( $query ); if ($result) { while( $row = @mysql_fetch_array( $result, MYSQL_ASSOC ) ) { news_box( $row['news'], $row['title'], $row['user'], $row['date'], $row['id'] ); } mysql_free_result($result); } else { news_box( 'Could not retrieve news entries!', 'Error', 'Error', 'Error'); } footer(); mysql_close($link); ?> I tried a few things but they failed....miserably. Hi there, As the question says i tried several things but i can't work it out and my knowledge about php isn't that well. $looponce = 1; foreach ($this->info as $k => $v) { if ( (($k == 'subject') && ($v['required'])) && (!$this->settings['customSubject'])) { for ($i = 0; $i <= 0; $i++) { $output[] = $this->display_errors('error_system_subject'); } } if ( (($k == 'name') && (!$v['required'])) || ((!array_key_exists("name", $this->info)) && ($looponce == 1)) ) { $output[] = $this->display_errors('error_system_name'); $looponce++; } } That is my loop that i check things in. What i'm more interested in is the name if statement. If currently checks for a name key in an array(below) and makes sure that it is set to required. If it's not set to required, print out a system error and die()'s. I'm looking for ways to remove the need for program errors and just change them to what is needed to run. What i know how to do is, get into the inner array, what i don't know is how to edit the data and put it back exactly as it was given to me. The inner array data can be put back in any order, but the outer array must be in exact order as it was given. above code $this->info = $formdata; $formdata = array( 'name' => array('name'=>"Full Name", 'required'=>false, 'type'=>'text'), # This needs to be required=>true, but i can't trust the user, which is why i have the error. 'telephone' => array('name'=>"Telephone", 'required'=>false, 'type'=>'phone'), ); Any help is greatly appreciated, also am i doing the foreach loop in the code above in an efficient manner or is there another way? I am producing a php script which will include some AJAX in the resultant web page, which will send some data to another php script for processing. If I create a php session in my original script, will the same session be accessed by the second script being run by the AJAX or will it create a new session? Hi People, I am on a deadline and finding that my code does not work in php5 and I have to change it to work. Just wonder if anyone can spot the obvious within my code. This all worked in php4 but now I have to rewrite it. Basically its a little order system. <? include("inc/connect.php"); // Continue start session. // We need to first check to see if an item with the SID and cat and product_code exists in the database, // if it does then we need to update that item, if not then we need to add the item // clean out any malicious data foreach ($_REQUEST as $k => $v) { $_REQUEST[$k] = (get_magic_quotes_gpc() ? strip_tags($v) : strip_tags(addslashes($v))); } session_start(); { $sql = "SELECT * FROM orders WHERE sid = '$PHPSESSID' AND product_id = '$product_id' "; $sql_result = mysql_query($sql); if (mysql_num_rows($sql_result) ==0) { # setup SQL statement $SQL = " INSERT INTO orders (sid,product_id,product_title,qty,standard_price,deluxe_price) VALUES ('$PHPSESSID','$product_id','$product_title','$qty','$standard_price','$deluxe_price')"; #execute SQL statement $result = mysql_db_query( azflowers,"$SQL",$connection ); # check for error if (!$result) { echo("ERROR: " . mysql_error() . "\n$SQL\n"); } } else { # setup SQL statement $SQL = " UPDATE orders SET qty = qty +1 WHERE sid = '$PHPSESSID' AND product_id = '$product_id' "; #execute SQL statement $result = mysql_db_query( azflowers,"$SQL",$connection ); # check for error if (!$result) { echo("ERROR: " . mysql_error() . "\n$SQL\n"); } } header("Location: http://www.site.com/site/cart.php?sid=$PHPSESSID"); exit; } ?> I'm trying to make my own shopping cart for the first time and having a problem getting products to add to it. All I get is "No product in cart.". Its nothing special now, I'm just trying to reach the first stepping stone of adding something successfully to the session. index.html Code: [Select] <?php session_start(); ?> <?php $cart = $_SESSION['cart']; if (!$cart) { echo "No product in cart."; } if ($cart) { foreach ($id) { echo $id; } } ?> <A href="index.html?action=add&id=1">Add to cart</A> What have I done wrong and what am I suppose to do? |
