PHP - How To 'remember' What's In Checkbox?
I am wondering how to keep a checkbox checked?
I have the folllowing code and it is outputting the correct info, but when i tick checkbox, and then click box "SAVE Days and Recipes Chosen" the checkbox doesn't get set. <?php for($i = 0; $i < $rows; $i++) { ?> <tr> <?php for($j = 0; $j < $columns; $j++) { echo "<TD><font color='8678E9'>" . $data[$i + ($j * $rows)] . "</font></TD>\n"; ?> <td><input type='checkbox' name=$R1 <?php if($R1=="checked"){$R1=="checked"; echo $R1;} elseif($R1=="unchecked"){$R1=="unchecked"; echo $R1;} ?> <td><?php echo"<TD><font color='3923D6'><font size=4>" . $data2[$i + ($j * $rows)] .

I'm trying to create a single page that contains a couple of checkboxes. When the first checkbox is checked I want to set a session. When the second chechbox is checked I want to set a different session. When the page submits ( to itself ) I'd like the checkboxes to reflect if they are checked or not. I can sort of do that part,but I'm having major issues with unsetting the sessions and updating the checkboxes to reflect this. Does anyone have a simple example on how to do this. Many Thanks Hi, I'm creating a remember me feature for my site which obviously sets a cookie and when the visitors loads the site again,he would already be logged in. This is a part of the code which is related : Code: [Select] $login_email = request_var('login_email', ''); $login_password = request_var('login_password', ''); $login_remember = (isset($_POST['remember']) && $_POST['remember'] == 1) ? true: false; setcookie('login_email', $_POST['login_email'], time()+60*60*24*365, '/','localhost',false); setcookie('login_password', md5($_POST['login_password']), time()+60*60*24*365, '/','localhost',false); HTML: Code: [Select] <strong class="normal"><input type="checkbox" name="remember" value="1">Remember</strong> I want to save live data into file. My script fetch the data (one by one) and save it into file by amend method. The live data is not regular and every time it must be checked if the value has been updated or it is still the last value. One way to do so is to read the last line of the file and compare it with the fetched value. But in this case, I need to read the file for every check. Is there a way to remember the last value and compare it with the coming value? to write only new value into the file. hi all, does anyone know the name of the following its a way to make a huge string than can have variables in it. look a bit like this but couldnt remember the right syntax, nor the name so was kinda hard to look on google. ABC>>> some stuff inside ABC; Hey guys not sure what this is called but does anyone have more information on it. Ok when you visit a part of a site or a profile or what ever?? :S:S and you redirect them to login how can u then send them back to where they was when they have logged in? hope someone can help. Okay, this is a head scratcher for me... About 10-15 years ago, there was this framework that seemed to be pretty popular in the LAMP work for quickly building websites. (I think it was written in PHP.) The thing I recall about it was that it you could create your own markup tags to markup up fields using curly brackets { }. I wish I could be more specific but this is all that is coming to mind. Any clues of what I might be thinking about? Hi guys, I wonder if any if you could help me: I have created a login page with "remember me" function... The page will redirect either to Admin Page or User Page depends their 'level'. But when I logged in as Admin and checked the box "remember me" and close all the browser to see IF the "remember me" work. When I open a new browser - and go to the index page - it is okay, I can view the page.... but it redirect me to the USER page NOT Admin page. Does anyone know why this happens? Time to ask a stupid question. I have a remember me cookie being set for my login page but I'm wondering what I need to do so that the next time the user comes back to the login page it already has the checkbox checked and the username in the username field which is the cookie. So I have a registration form setup. When the user submits the form it sets session variables for each of the form fields and then checks the database to see if the username is taken. If the username is taken I have the form fields values to display the value of what the user just submitted. My problem is I have 2 drop down fields: States and Countries I am using the the following for my countries dropdown box and it works to remember the selection the user made, BUT how can I have it remember the option name as well as the option value? IE if the user chooses United States of America and submits the form I want the drop down to display United States of America not US here is the code: <select id="country" name="country" tabindex = "511"> <option value="<?php if(isset($_SESSION['country'])) echo $_SESSION['country']; ?>" selected="<?php if(isset($_SESSION['country'])) echo $_SESSION['country']; ?>"><?php if(isset($_SESSION['country'])) echo $_SESSION['country']; ?></option> <option value="">(please select a country)</option> <option value="AF">Afghanistan</option> <option value="AL">Albania</option>

number with PHP or do I need to make use of MySQL? I want to generate an equation with submit button 1 and echo it out, and then I want the script to calculate the printed out equation with submit button 2. The problem: As soon as I click submit button 2, the numbers change into different random numbers, since the PHP starts scanning from the top of the file again as soon as the second button has been pressed. $gen = $_POST['gen']; $calc = $_POST['calc']; $x1 = random_number (); $x2 = random_number (); $op = random_op (); echo " <form action='' method='POST'> <input type='submit' name='gen' value='Generate' /><br /> <input type='submit' name='calc' value='Calculate' /> </form> "; if ($gen) { echo "$x1 $op $x2 = ? <br /><br />"; } if ($calc) { switch ($op) { case '+' : $row_1 = $x1 + $x2; break; case '-' : $row_1 = $x1 - $x2; break; case '*' : $row_1 = $x1 * $x2; break; case '/' : $row_1 = $x1 / $x2; break; } echo "$x1 $op $x2 = $row_1"; } I could of course insert the generated numbers into the database and fetch it out again, but I was wondering if it's possible to remember the numbers (even when the 2nd submit buttons has been pressed) within PHP as well? thanks. I am about to attempt to write my first php script from scratch after a year or so of copying and adapting code. I am going to do a registration/login in system and thinking ahead, want to make sure that once someone is logged in, this information is passed from page to page (so they do not have to log in again on each page) and I would also like to provide a 'Remember Me' option. I have had a read up and from what I gather, sessions would be better for showing someone is logged in from page to page and cookies would be the only way to implement a 'Remember Me'. Would this be the best way to approach this or is/are there better ways? Thanks in advance Steve I would like to know how to take details of my 'users' table from mysql database and check if that user is logged in using cookies or sessions somehow and have that users username displayed on my site, something like: user logged in as: (username), how is this done? What would you guys need to see in order for you to help me? im guessing the login and register scripts which are below, if you need anymore let me know, thanks. Login script: Code: [Select] <?php if(isset($_POST['submit'])){ //check for submit button click $username = $_POST['myusername']; $password = $_POST['mypassword']; // proceed with rest of code $self = $_SERVER['PHP_SELF']; $referer = $_SERVER['HTTP_REFERER']; #if either form field is empty return to the log-in page if( (!$username ) or (!$password ) ) { header( "Location:$referer" ); exit(); } #connect to mysql $conn = @mysql_connect( "myserver", "username", "password" ) or die( "Could not connect" ); #select database $rs = @mysql_select_db( "removalspacelogin", $conn ) or die ( "Could not select db" ); #create query $sql="select * from users where username = '$username' and upassword = '$password'"; #execute query $rs = mysql_query( $sql, $conn ) or die( mysql_error() ); #get number of rows that match username and password $num = mysql_numrows( $rs ); #if there is a match the log-in is done if( $num != 0 ) { header( "Location:login_success.php" ); } else #or return to: login.php { header( "Location:$referer" ); exit(); } } ?> <?php ini_set("display_errors","ON"); ?> <html> <head><title>Check-login</title></head> <body> <?php echo( $msg ); ?> </body> </html> Register users script: Code: [Select] <?PHP $user_name = "removalspace"; $password = "123"; $database = "removalspacelogin"; $server = "removalspacecom.ipagemysql.com"; $db_handle = mysql_connect($server, $user_name, $password); $db_found = mysql_select_db($database, $db_handle); if ($db_found) { $SQL = "INSERT INTO users (username, upassword, email) VALUES ('" .$username.

"')"; $result = mysql_query($SQL); header( 'Location: http://www.removalspace.com/index.php' ); exit(); } else { print "Database NOT Found "; mysql_close($db_handle); } ?> Hi everyone, On my website i have a drop down box on the account information page that has a list of countries. In the example below, im using the php to do 2 things, 1: if the user changes the country and clicks submit but an error is found on the page, rather than revert back to the original country it stays as the newly selected one. 2: if the user does not change the country, the country from the database is simple displayed. As you can see below it is taking up quite a bit of code. I was wondering if anybody has any ideas how i can make this smaller? <select name="country"> <option value="select" selected>Select...</option> <option value="Afganistan" <?php if ($submit) { if ($country == "Afganistan"){ echo "selected";}} else {if ($row['country'] == "Afganistan") {echo "selected";}} ?>>Afghanistan</option> <option value="Albania" <?php if ($submit) {if ($country == "Albania"){echo "selected";}} else {if ($row['country'] == "Albania") {echo "selected";}} ?>>Albania</option> <option value="Algeria" <?php if ($submit) {if ($country == "Algeria"){echo "selected";}} else {if ($row['country'] == "Algeria") {echo "selected";}} ?>>Algeria</option> <option value="American Samoa" <?php if ($submit) {if ($country == "American Samoa"){echo "selected";}} else {if ($row['country'] == "American Samoa") {echo "selected";}} ?>>American Samoa</option> <option value="Andorra"<?php if ($submit) {if ($country == "Andorra"){echo "selected";}} else {if ($row['country'] == "Andorra") {echo "selected";}} ?>>Andorra</option> <option value="Angola"<?php if ($submit) {if ($country == "Angola"){echo "selected";}} else {if ($row['country'] == "Angola") {echo "selected";}} ?>>Angola</option> Thanks I am working on a site that is going to have hundreds of polls that people can vote on. Once any user creates a new poll (vote: Hayden Panettiere vs. Kristen Bell as an example) I want to have the database remember what member voted on what, for each poll. So user 1 voted Hayden, user 327 voted Kristen.. etc.. I expect up to 500 users to vote on each topic, but a new column to store each username that voted seems insane. I was thinking arrays, but am not sure if that would work. I don't think that a new table per poll would be very efficient either, it would be like 500++ tables on one database. To explain better, my username is Paradox and I vote for Kristen Bell. When I look at this database I want to see: ID Title Option1 Option2 People who voted option 1(27 people) People who voted option 2(783 people) 1 Heroes 27 783 {Blah, Blah, Blah} {Paradox, Blah, Blah} Is an array a good way to go about this? Because I also want to be able to expand the array to notify each member they voted with the winning or losing team once the poll expires. Hi there got a bit of a logic question here. I have been looking at doing a remember username and password for a persons login form. You'd need to set this as a cookie right? But when doing so would you place it just as the user has entered the form, or when the user has actually successfully logged in, I know mostly this 1st question would be up to me, but what would you do in your own opinion? On a second note to that, I have been going on this logic, just to try and work it out for myself but it keeps coming out with the encrypted password, is there a much better tutorial than going off my own assumptions? Here's the logic: Code: [Select] <?php session_name('jeremysmith_remember_login'); session_start(); ini_set('display_errors', true); // see whats in the cookies overall! print_r($_COOKIE); // now do logic on the form example: if(!array_key_exists('login', $_POST)) { $message = 'User has not logged in yet, please login below:'; require 'form.php'; } else { if(strlen(trim($_POST['username'])) > 0 && strlen(trim($_POST['password'])) > 0) { // now save them to a cookie maybe? mysql_connect('localhost', '******', '*****') or die (mysql_error()); mysql_select_db('test') or die (mysql_error()); $username = mysql_real_escape_string($_POST['username']); $password = mysql_real_escape_string($_POST['password']); $sql = sprintf("SELECT * FROM users WHERE username LIKE '$username' AND password LIKE sha1('$password')"); $result = mysql_query($sql) or die (mysql_error()); if($result) { if(mysql_num_rows($result) === 1) { $_SESSION['logged_in'] = true; // this will be our only check for now though! if(IsSet($_POST['remember_login'])) { // but don't remember if they have not logged in, what would be the point in that? setcookie("username", $_POST['username']); setcookie("password", $_POST['password']); header('location: success.php'); } } } else { die(mysql_error()); } } else { $username = trim($_POST['username']); $error = 'You did not enter all the fields required to login, please try again'; require 'auth_form.php'; } } I am just a bit confused, any guidance is massively appreciated, Jeremy. I'm an experienced programmer with several languages (COBOL, REXX, Java, Javascript, etc.) under my belt over many years but I know very little about PHP. I dabbled in it a bit a year or two back and got it to do what I wanted to do but I'm not sure how to do what I currently need.
A bit of context: I have designed a website where the user can choose between various page styles; each style invokes different CSS to give them a different visual experience of the site. They can select the style they want via View/Style in Internet Exploder and View/Page Style in Firefox but that preference is only remembered as long as they're on that page. As soon as they move to another page on the site, they have to choose the alternate style again or live with the default style. I want them to be able to select that preference ONCE, the store it in a cookie specifically for them, then keep using that style every time they visit the site. (Naturally, I want them to be able to change the style and then remember the new style as well.) There will be many visitors and each will want that same capability. I currently don't require any login to the site. (I'm toying with password-protecting some of the site down the road but that's not a factor in this page style thing that I'm talking about here.
Now, my questions.
I've found a variety of short articles describing how to use setCookie() to create the cookie (and delete it later) and getCookie() or the newer echo $_COOKIE["name"] to determine the cookie value. However, I am NOT seeing anything that says where I put the code to set and/or read the code within my web pages. I would really appreciate an explanation of that! I expect to write short fragments of php code to do those jobs which I will then imbed within my web pages via SSI (Server Side Includes). Is that reasonable or is there a better way?
Also:
1. When the user clicks on the desired Style in the View/Style menu, how do I detect what choice they made?
2. Should the name of the cookie be something like "pageStyle" or should it be something that uniquely identifies the user so that the right cookie is retrieved when the come back? If the latter, what value should I use and how should I obtain it? I assume that something unique about the user obtained from their headers is far better than displaying a dialog and asking them for some unique identifier.
I'd rather stay away from Javascript in any of this functionality since I can't rely on it being turned on.
One quick aside while I'm here. Does anyone know how to change the page style if visitors use Google Chrome or Opera? I can't even FIND options for changing the page style in my copies of those two browsers and both are current versions. Do they not support differing page styles at all or do they just hide the technique to choose the style very effectively?

I am trying to make a login which works perfectly until I try and add remember me functionality into the User class. The situation: The script is fetching data from the database and printing it out with a while loop, at the same time the rows are being broken up into pages with pagination. The problem: I'm using if and elseif statements for a sorting and ordering functionality. When I now choose a certain category to print out ONLY the chosen category, then the pagination will still be intact. But as soon as I click forward on the pagination navigation links, a page refresh (reload) will happen and the query will default to it's default setting which is category = ALL (and not anymore that specific category I chose earlier). My question: Is there any way to make the script remember the last pressed submit condition? Meaning that if I choose a certain category which should be printed, then the chosen category still remains chosen even if I click the pagination links which cause a page reload? Here's a small script excerpt, to help picture the example: $select_category is taken with $_REQUEST from a drop down menu. // ALL but NO OTHER if (($select_category == 'All') || (!isset($select_category)) && (!isset($most_liked))) { $query = "SELECT * FROM con, user WHERE con.user_id = user.user_id ORDER BY contributed_date DESC"; pagination_start ($dbc, $query); $offset = $pag_array[0]; $rows_per_page = $pag_array[1]; $query = $query . " LIMIT $offset, $rows_per_page"; knuffix_list ($query, $dbc); pagination_end ($pag_array); // CATEGORY but NOT most_liked } elseif (isset($select_category) && !isset($most_liked)) { $query = "SELECT * FROM con, user WHERE con.user_id = user.user_id AND category = '$select_category' ORDER BY contributed_date DESC"; pagination_start ($dbc, $query); $offset = $pag_array[0]; $rows_per_page = $pag_array[1]; $query = $query . " LIMIT $offset, $rows_per_page"; knuffix_list ($query, $dbc); pagination_end ($pag_array); This problem happens in both IE9 and Chrome 13.0.782.112 m on Windows If I close the browser down, my session data is gone on browser restart, if however I just close the tab leaving other tabs say with BBC news and restart my app in a new tab, both browsers remember the old session data. Since the intended user could do this at any time before completing a transaction, I don't actually get a chance to destroy the session this only happens if they complete payment for their order via.. Code: [Select] session_destroy(); $conn->commit(); $conn->autocommit(TRUE); In an attempt to clean up I tried various combinations at the top of the start page "index.php".. Code: [Select] session_start(); // $_SESSION = array(); session_destroy($_SESSION['cart']); session_destroy($_SESSION['address']); // $_SESSION['cart'] = array(); // $_SESSION['address'] = array(); // session_destroy(); Can anyone please shed any light on this behaviour difference?
