PHP - Sessions
Hello everyone,
i'm new to php and i'm having hard time with sessions i'm trying to create a php file with a drop down menu and when you select an item from the drop down menu, you could retreve it from another page. for example: a1.php Code: [Select] <?php session_start(); if(isset($_POST['color'])) { $_SESSION['blue']='blue'; $_SESSION['red']='red'; $_SESSION['green']='green'; $_SESSION['orange']='orange'; } ?> <html> <body> <form id="shirt" method="post" action="a2.php"> <p> <select name="Size"> <option value="invalid">Select a size ...</option> <option value="blue">blue</option> <option value="red">red</option> <option value="green">green</option> <option value="orange">orange</option> </select> <br /> <input type="Submit" value="Add" name="Add" /> </p> </form> </body> </html> when the user chooses a color, it adds it to the session and then when the user clicks add, he is redirected to another page named a2.php which shows the color is added. if the user goes back to the original page and adds the same color again it shows that he added the item again: Color: ----------- Quantity: Red ----------- 2 a2.php Code: [Select] <?php session_start(); $item_id = $_GET[id]; $action = $_GET[action]; switch($action) { case "add": $_SESSION['color'][$item_id]++; break; case "remove": $_SESSION['color'][$item_id]--; if($_SESSION['color'][$item_id] == 0) unset($_SESSION['color'][$item_id]); break; case "empty": unset($_SESSION['color']); break; } ?> sorry if my question is not clear, any help is appreciated Thank You, Similar TutorialsI am in the process of opening my web site to the general public. Right now you have to have a username and password to see anything on the site. What I am looking to do is make it so anyone can see most things on the site. There will still be user accounts for things like admins and submitting ideas. What i have now is some links that look at the user rank and only show up if you are higher then a rank. What I need to do is make it so you don't need to log in to see the site but you still need to log in to edit things. Here is my sessions scrip Code: [Select] <?php session_start(); if(!$_SESSION['login']){ $_SESSION['rank']; $_SESSION['loggedinusername'] = $loggedinusername; $_SESSION['loggedinuseremail'] = $loggedinuseremail; header("location:login.php"); } $rank=$_SESSION['rank']; $loggedinusername=$_SESSION['loggedinusername']; $loggedinuseremail=$_SESSION['loggedinuseremail']; ?> How do I edit this so you are free to move around the site even if your not logged in? Thanks Hello everyone, By default when someone comes to my site, it is the unencrypted web page (http://www.mydomain.com). I recently purchased a ssl certificate so when a user logs in, their password is encrypted (Posted to https://mydomain.com). Once the form is posted, the session is set and the header("Location: http://www.mydomain.com"); function is executed to bring them back to the unencrypted version of the site. However, now when a user tries to login, my site seems to drop the session when the location is set to the unencrypted version of the site. How do sites go about using a secure login form and running on the regular version of the site? Thanks! weee Hi, I have an admin area to update users detials etc.. I want this area to be secure so only admins can access it, Currently anyone and everyone can access the page.

When the user posts their form i want the session to be inserted into the database but the session always comes up empty. this is what happens when they upload their file Setting the session and moving the file: session_start(); $_SESSION['attachment'] = "EXAMPLE"; move_uploaded_file($_FILES['Filedata']['tmp_name'], "../attachments/" . time() . $_FILES['Filedata']['name']); and then when they submit their form(textarea) it uploads the contents to the database and the contents of the session aswell. Why is this session always empty? I am new to SESSIONS and have a quick question about them. I want to use sesssions on my site but was wondering if they would work for the follow senario. Say a customer visits my url: http://www.mysite.com/?id=2 Now what i am doing is taking the id out of the URL using sessions and redirecting the user to http://www.mysite.com while my session ($_SESSION['id']) holds the value 2 in it. I have this working great, i believe it just looks better. Now if my customer decides to buy my product via paypal and is directed off my site while he/she is paying for said item on paypal when they return could i still use some of the information that i stored in my session?? I know i could use post and get to pass through paypal but unfortunately i have to use sessions for what i am trying to do. hey i think i may have stored session variables incorrectly Code: [Select] $_SESSION['tel'] = $_GET['Lat']; $_SESSION['Lon'] = $_GET['Lon']; $_SESSION['Lat'] = $_GET['Lat']; is what i used to set the session variables with the data i then enter these into a table and they enter the correct information but two pages down the line i try to access them however i just get undefined variable when i set the variable is equal to the session. Code: [Select] $MyLon = $_SESSION['Lon']; $MyLat = $_SESSION['Lat']; the following is the errorr Quote Notice: Undefined index: Lat in Hey Guys, Me again! Still working on this bloody database! Okay, so I have a site that people can add a record to a database. This record is filled using a form and the form contains an image that can be uploaded. This works fine. Then there's the ability to search a record based on a boolean search which displays a table with the record data and displays a thumbnail of the photo. This also works fine. Then I have a script that (once it's working) will allow you to edit the record. This is where I'm having issues. Here's my process for the form: User searches for the record by using a boolean search Search finds the record and displays a form containing the original values in the database User changes some parts of the original record using the form Form then updates the database with the new values The problem I'm having is with the photo function. If there's no photo attached, I was getting an error saying that the photo field could not be empty. So I used the following process: User searches for the record using edit.php Form is displayed using edit_process.php edit_process.php is posted to update.php that has conditions to check if the file upload field is empty or not If the field is empty, then it requires updatenophoto.php If the field has a new image, it uses updatephoto.php When I submit the form to the update.php script, it does nothing and gives me a blank page. Here's my code for each of the parts (hit the character limit, code in comments): session_save_path("/home/content/q/1/w/q1w2e3r4t5y6u7/html/tmp/"); session_start(); I have this at the head of my index page. I'd like to count how many files are in temp to find out how many users are online. After going to my index page, i checked how many users were online via the script I wrote and it said 1. I refreshed the page and it said 2. It went as high as 10 with each refresh and then I stopped because something isn't right. I checked my temp folder and there are 10 temp files. How can one page visitor start so many unique sessions? Is there a way to prevent this? I'm using the session start command with dual purpose. One, if a user loads the page. Secondly, to check if $_SESSION['active'] exists so I know this is a registered user. How can i limit the amount of sessions started by an unknown user and efficiently count how many files are in the temp directory? I there. I am making a small game, either you or the computer win depending on who's life hit 0 first I am using sessions to hold the health values, however I need a little bit of help. How do I make it actually go down after each move until one hits 0? Here is my script and thanks in advance...

Are these two variables the same? Im makigna simple login system for a sight but i only want them to have to login if they want to go to the shopping cart i have t implement a session_start() on every page before the cart page so the home page products page etc etc and then on the cart page ive a simple function that checks if their logged in if not then it will direct them to the login page if they are they should just continue is this the correct way to do it ? thanx I am trying to create a blog and visitor log, where I should be able to log in as admin and add the item and see the visitor log.

The problem is that if someone decides not to send the form and navigates away from the page, and then decides to email another page, it saves the previous url. How can I have it so that it clears the previous url and uses the new one? Code: [Select] if(!isset($_SESSION['referrer'])){ //get the referrer if ($_SERVER['HTTP_REFERER']){ $referrer = $_SERVER['HTTP_REFERER']; } else{ $referrer = "http://www.mcse-training-classes.com"; } //save it in a session $_SESSION['referrer'] = $referrer; } I haven't used sessions much until now, so this is probably due to my ignorance. I have a page that sets the session variable, and if I print from that page, the session variable (an array) is correct. But when I move to the next page, the same session variable has old, old, wrong data. The $arrAttendeeList is an exploded list from a textarea on a form turned into an array. Example: This page, let's call it page1.php, sets the variable: Code: [Select] <?php $_SESSION['arrAttendeeList'] = $arrAttendeeList; foreach ($_SESSION['arrAttendeeList'] as $temp) { print "$temp <br />"; } exit; ?> Results: Smithers, Waylon Bouvier, Selma Brockman, Kent But the next page, page2.php, when I call the same variable: Code: [Select] <?php foreach ($_SESSION['arrAttendeeList'] as $temp) { print "<br />$temp <br>"; } ?> I get yesterday's data: Smithers, Waylon Bouvier, Selma I've tried setting the session var to null but with the same results. Do I need to kill the session var before setting it to something else? Thanks - Hi Something strange is happening and I can't understand it. A user can access an availability page of accommodation and book ita room, this works fine, and goes from availability to the booking form and back quite well, carrying the room id of the accommdation and room/s selected in a session. If they close the browser down and open the availability page again all the rooms are there as before, but when they select a room and go to the booking form the session of the room id and the rooms selected are empty. If I do a session destroy and open the browser up again everything works fine again. I have tried this in Chrome and Firefox and it seems to work fine Any help would be appreciated hey on my page a list of people get listed by a category u choose if u choose a category and click ok, u are sent to the same page, and i get the category with POST if(isset ($_POST['type'])) { $gameholder = $_POST['game']; $typeholder = $_POST['type']; } this works ... the list of people is 30 members / page when u click on page 2, the post doesnt work anymore, and i get errors, logic ... now i want to get around this with making a session emediatly when the vars get out of POST if(isset ($_POST['type'])) { $gameholder = $_POST['game']; $typeholder = $_POST['type']; $_session['gameholder'] = $gameholder; $_session['typeholder'] = $typeholder; print $_session['gameholder']; } this also works now i want when people click on page 2, the needed vars will come out of the Sessions, and not out of POST so i did this if(!isset ($_POST['type'])) { $gameholder = $_session['gameholder']; $typeholder = $_session['typeholder']; } but this is not working theres nothing in $gameholder also when i move the print session out of the if, it should show when someone clicks page 2 but its not ... any suggestions on this? thanks! |
