PHP - Php Session Passing Variables
Having some problems with PHP session i currently use cookies to log users in, but i have decided to use php session instead but i can get it to work, it simply dose not pass the variables unless include session id in every single link on my website,
can anyone tell me where i am going wrong these are the session setting from php.in session.use_cookies = 1 session.use_only_cookies = 0 session.name = usersesid session.auto_start = 1 session.cookie_lifetime = 0 session.referer_check = 1 session.cache_expire = 180 session.use_trans_sid = 1 Similar TutorialsHola, I'm trying to create a web form to insert info into my database using session variables. I'm at my wits end at this point. The reset button does its job but when you click submit it doesn't do anything. I'm using the template from the lynda.com essential php web form tutorials. Any help would be appreciated Here is the client-side header code I'm working with, <?php header("Expires: Thu, 17 May 2001 10:17:17 GMT"); // Date in the past header ("Last-Modified: " . gmdate("D, d M Y H:i:s") .

$arVal = array(); require_once("include/session_funcs1.php"); // make sure the seesion vars are initialized... reset ($arVal); while (list ($key, $val) = each ($arVal)) { if (!isset($_SESSION[$key])) $_SESSION[$key] = ""; } if ($_SESSION["eventgenre_sel"] == "") $_SESSION["eventgenre_sel"] = 0; // if the bFlg is true then some validation problems in the data. // namely a blank field or a submission without the feedback page. // just present a general error... $flg = "";

When clicking on them you're redirected to the client record update page. This is how I am linking to taht page now: Code: [Select] <a href="DIST_clientes_update.php?id_cliente=<?php echo $row_clients_RS['id_cliente']; ?>The problem with this is that the client id is appended to the url and so if the user chnges it will be able to access records from a different user...and I dont want that. So I have created a session: Code: [Select] $_SESSION["idCliente"] = $row_clients_RS['id_cliente'];but how do I pass it to the update page without showing in the url? Thanks Hello, we got a site running in to different servers, the other one is a sub domain that will be use as internal pages and the other one is external. As of that I need to pass session to see if a user details.
Is there a another secure way to pass session data to other server without storing on the database?
I have my php pages set up like this: 1. log in with login.php 2. that sends you to main.php 3. in main.php, there are links to page-a.php, page-b.php, page-c.php, etc. when you type in a password at login.php, it passes your input to main.php. the correct password is hardcoded in main.php. if it matches, a session variable is set, which should be able to be used on page-a.php, page-b.php, page-c.php, etc. to verify that whoever accesses those pages has gone through the login process. if the session variable doesn't match (or null) the user is redirected to the login page. also the session variable is checked (recursively) when accessing main.php, just like the other pages. the problem is, it's as if each page starts over. the session variable does not make it beyond the page that sets it. it should be passed on to the next page but it's not. I used an echo statement in page-a.php to verify and rem'd out the rest of the code. no echo because session value is null, page goes on to load the html. without the code rem'd out it redirects the user to login.php. code: LOGIN.PHP <? session_start(); if(isset($_SESSION['aaa'])) unset($_SESSION['aaa']); ?> <html> <head> <title>title</title> </head> <body> <table width="400" align="center" border="0" bordercolor="#000099" bordercolordark="#000066" bordercolorlight="#6666FF"> <tr bgcolor="#B0C4DE"> <td> <form action="main.php" method="POST"> <p align="center"><strong><font size="2" face="Verdana, Arial, Helvetica, sans-serif" color="#FFFFFF"><br> Password</font></strong> <input name="pwfield" type="password" value size="20" maxlength=20> <input type="submit" value="Login"></p> </form> </td></tr></table> </body></html> MAIN.PHP <? if ($_SESSION['aaa']!="abcdef") { $password="twinkies"; if ($_POST["pwfield"]==$password) $_SESSION['aaa']="abcdef"; // successful login else {header("Location: login.php"); exit();} } ?> <html> <head> <title>title</title> </head> <body> <a href="page-a.php">Page A</a> <a href="page-b.php">Page B</a> <a href="page-c.php">Page C</a> </body></html> PAGE-A.PHP <? echo $_SESSION['aaa']; //if ($_SESSION['aaa']!="abcdef") //header("Location: login.php"); //exit(); ?> <html> <head> <title>title</title> </head> <body> ... I'm building a login page that then redirects to a new page. But it seems the session isn't working. But I don't know much about sessions, so I'm not sure what I might be doing wrong. The login page sets the session with this code: Code: [Select] // Fetch the result - This will tell us whether this user exists $userExists = mysql_fetch_assoc($doQuery); // If user exists log them in if($userExists){ mysql_free_result($doQuery); mysql_close(); // Set the SESSION variables $_SESSION['first_name'] = $userExists['first_name']; $_SESSION['id'] = $userExists['id']; The page that it redirects to is this: Code: [Select] <?php session_start(); if(isset($_SESSION['id'])) { echo "<html><body><p> You are now logged in,{$_SESSION['ID']}.</p>"; } else { echo 'something went wrong'; exit(); } ob_end_flush(); ?> The code below is a form the gets information from a database and post it into the appropriate field. I am having a problem with the while loop. All the variables before the while loop work just great and echo out how they should. But everything after the while loop does not work. I know it has something to do with the while loop because when I take the while loop out everything works as it should. Can anyone please help me with this? <? $id = $_POST["id"]; $therapy = $_POST["therapy"]; db_connect(); $query=mysql_query("select * from student where student_id = $id") or die ("invalid query"); $row=mysql_fetch_array($query); print "<table width='330' border=0 align='center'> <form method='POST' action='table.php'> <td>*First Name:</td> <td>*Last Name:</td> <tr>"; ?> <td width="157"><input size="23" name="first_name" value="<?php echo "$row[first_name]"; ?>" /></td> <td width="138"><input type="text" size="23" name="surname" value="<?php echo "$row[surname]"; ?>" /></td> </tr> <tr> <td>Level:</td> <td>Therapy:</td> </tr> <tr> <td> <select name="program_level"> <option <?php if ($row[program_level]=='1') echo "selected=yes"; ?> value="1">O&A</option> <option <?php if ($row[program_level]=='2') echo "selected=yes"; ?> value="2">Student</option> <option <?php if ($row[program_level]=='3') echo "selected=yes"; ?> value="3">Supervisor</option> <option <?php if ($row[program_level]=='4') echo "selected=yes"; ?> value="4">Manager</option> <option <?php if ($row[program_level]=='5') echo "selected=yes"; ?> value="5">Director</option> <option <?php if ($row[program_level]=='6') echo "selected=yes"; ?> value="6">Graduate</option> </select> </td> <td> <!-- Auto drop down for therapist names--> <? $query2=mysql_query("select * from therapy_info;"); ?> <select name='therapy'> <? while ($row=mysql_fetch_assoc($query2)){ ?> <option value="<? echo "$row[therapy_name]"; ?>"> <? echo "$row[therapy_name]"; } ?> </option> </select> <!-- End Auto drop down for therapist names--> </td> </tr> <tr> <td>Active:<?php echo "$row[active]"; ?></td> </tr> <tr> <td><select name='active' value='$row[active]'> <option <?php if ($row[active]=='1') echo "selected=yes"; ?> value='1'>Active</option> <option <?php if ($row[active]=='0') echo "selected=yes"; ?> value='0'>Inactive</option> </select> </td> </tr> <?php print "<tr> <td><input type='submit' value='Change' name='button' /></td> <input type='hidden' name='id' value='$id' />"; ?> <input type='hidden' name='$hardcode_session' /> <? print "</tr> </form> </table>"; Hi First post here. Long time reader! I'm looking to gauge the general practices of dealing with variables between pages. I'd always pass my variables through the POST. Im normally always doing a post back and processing the data at the top of the page. I never liked the query string as it open to manipulation, but can see its use for a search results page and saving the url. I came from a ASP background and we would only use session variables for holding user login information as the windows server had a habit of restarting the pool and loosing the session. We didn't want this happening, for example, when doing an e-commerce transaction. We always felt the post was the most robust method. Now Im using php and all the great features it has. I was looking to see what the more experience php developers used and am I right sticking to the post method, or is utilising session a more modern way of doing things. I've a few years experience doing web dev, just thought I touch base on a few issues to make sure I'm still heading in the right direction. Thanks for any advice guys! hai everybody....
1. can any one let me know how to pass a variable from view to controller in CodeIgniter...
2. if possible send me a complete login application...developed by using CodeIgniter....
Thanks & Regards,
Shankaar.
I normally don't work with PHP or rather I'm learning as I go..and this is pretty much my last barrier between completing this project. Anyway here are my two files: http://pastebin.com/aThU3akC - file i want to grab values from and pass to the file below http://pastebin.com/kTYHr99p - file that is suppose to display the values in $transmessage Basically I need the variables defined in the first file to be passed and usable in the second and I'm not sure why I can't Hello all, So I've picked up a PHP book in an attempt to learn it. The issue I'm having is preventing me from getting any further. They have me creating a simple order form, but the data is not passing from the HTML page to the PHP Processing file. I know there are other ways of doing this that I'm unaware of, but this code is verbatam to what we are isntructed to type within the book itself. Here is the code orderform.html: Code: [Select] <html> <body> <form action="processorder.php" method="post"> <table border="0"> <tr bgcolor="#cccccc"> <td width="150">Item</td> <td width="15">Quantity</td> </tr> <tr> <td>Tires</td> <td align="center"><input type="text" name="tireqty" size="3" maxlength="3"></td> </tr> <tr> <td>Oil</td> <td align="center"><input type="text" name="oilqty" size="3" maxlength="3"></td> </tr> <tr> <td>Spark Plugs</td> <td align="center"><input type="text" name="sparkqty" size="3" maxlength="3"></td> </tr> <tr> <td>How did you find Bob's?</td> <td><select name="find"> <option value = "a">I'm a regular customer</option> <option value = "b">TV advertising</option> <option value = "c">Phone directory</option> <option value = "d">Word of mouth</option> </select> </td> </tr> <tr> <td colspan="2" align="center"><input type="submit" value="Submit Order"></td> </tr> </table> </form> </body> </html> processorder.php: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Bobs Auto Parts - Order Results</title> </head> <body> <h1>Bobs Auto Parts</h1> <h2>Order Results</h2> <?php $tireqty = $_post['tireqty']; $oilqty = $_post['oilqty']; $sparkqty = $_post['sparkqty']; echo "<p>Order Processed at "; echo date('H:i, jS F Y'); echo "</p>"; echo '<p>Your order is as follows: </p>'; echo $tireqty.' tires<br />'; echo $oilqty.' bottles of oil<br />'; echo $sparkqty.' spark plugs<br />'; $totalqty = 0; $totalamount = 0.00; define('TIREPRICE', 100); define('OILPRICE', 10); define('SPARKPRICE', 4); ?> </body> </html> For some reason the values on the processing form dont show up.

The writers website isnt any help.... Regards, sapper6fd I'm creating this URL to pass variables to use from one Page to another:
http://eg10basketbal...Borgman&team=16
My WP site is seeing the first variable but not the second. After some searching I've found this suggestion, but it's not working for me:
function add_query_vars_filter( $vars ) {
$vars[] = "nameFull";
$vars[] = "team";
return $vars;

I tried putting this in the wp-includes/functions.php file of the, but ended up with a fatal error. I have since added it to my theme's functions.php file. There isn't an error, but it doesn't yield recognition of my second variable.
Hi, I'm trying to pass a variable into a URL and apparently I'm doing it wrong this code is OK Code: [Select] $id = $3; echo '<a href="newPage.php?id=3"></a> If I use Code: [Select] $id = $_GET['id']; echo $id; on the newPage.php, I echo 3 whereas, if I do Code: [Select] $id = $3; echo '<a href="newPage.php?id="'.$id.'"></a> when echo out on the newPage.php it prints out nothing also, in current url look like this: Code: [Select] www.site.com/newPage.php?id= What am I doing wrong? Many thanks I'm a newbie here and to php and Javascript. So hello all. I am trying to get a portion of a file name passed from one file (first.php) which displays a MySql table. One of the fields is a link that is supposed to open a popup window (second.php) and begin playing a mp3 file with the flash media player. I have everything (almost) working. The table displays as it should, the link is fine. However, I can not get the popup to open with the dimensions I asked for. It opens in a full size new window. And the mp3 will not play. I get the message from the player "we are unable to connect...etc etc". The file name shows up in the status bar and in the URL window. In the file first.php, the table displays, the links appear to be active. when clicked the new window opens, the file names carry over but I can not get the file to play. The player loads (in file second.php) but I get the message from the player "we are unable to connect...etc etc". I suspect it is in the syntax. I have tried so many combinations I can't list them here and so far I have been unable to find anything on google, etc to answer this. After almost three days I have resorted to here. This may not even be the right place for me. Javascript may be my best bet for all I know. Can someone please look over what I have and at least point me in the right direction? Any help is greatly appreciated as this is my first attempt at a website.

It searches my MySQL database for the name of a given item within a theme: $relative = 'http://www.domain.com/wp-content/'; $url1= $relative . 'themes/arjuna-x/itemspec.php?type='; $url2='&item='; <a class="entry-thumbnails-link" href="<?php echo $url1.'Themes'.$url2.$rowThemes['Theme']; ?>"> The output is as follows: http://www.domain.com/wp-content/themes/arjuna-x/itemspec.php?type=Themes&item=(insert variable here) All is good up to this point. My problem however, is that some items (in this case: theme names) have apostrophes in them. For example: April Fool's. This results in breaking my php code. How can I get php to call these variables with apostrophes so that they don't break my php? Alright, So i want to pass a session from www.mysite.com to mobile.mysite.com And i'm doing so by calling this on the top of every page on each site: <?php session_set_cookie_params(360000, "/",".mysite.com"); session_start(); print_r($_SESSION); ?> yet, the session data that is set on one subdomain is NOT printed on the other subdomain. I've even tried destroying the sessions several times to start over. But it won't work. What could be up? Thanks I have a script that was written and tested on another server, but now when I transferred it to the live server, session values are not being passed. I made a couple test pages to check and confirmed that the only issue is the session variables. Here is the test I performed. Please tell me what I'm missing: page1.php <? session_start(); $_SESSION['var1'] = 'testing'; print_r($_SESSION); ?> Returns: Array ( [var1] => testing ) page2.php <? session_start(); print_r($_SESSION); ?> Returns: Array () Hi All, I am using the uploadify script available at http://uploadify.com/ Now I can get the file uploads working fine with the script below: Code: [Select] <?php session_start(); ?> <link href="/uploadify/uploadify.css" rel="stylesheet" type="text/css" /> <script type="text/javascript" src="/uploadify/jquery-1.3.2.min.js"></script> <script type="text/javascript" src="/uploadify/swfobject.js"></script> <script type="text/javascript" src="/uploadify/jquery.uploadify.v2.1.0.min.js"></script> <input id="fileInput" name="fileInput" type="file" /> <script type="text/javascript">// <![CDATA[ $(document).ready(function() { $('#fileInput').uploadify({ 'uploader' : '/uploadify/uploadify.swf', 'script' : '/uploadify/uploadify.php', 'cancelImg' : '/uploadify/cancel.png', 'auto' : true, 'folder' : '<?php echo $_SESSION['filepath']."/downloads/"; ?>', 'multi' : true }); }); // ]]></script> The problem that I am having is that I also store the mysql connection details in session vars (they change depending on who logs in). I have tried a number of ways of "passing" these session vars to the uploadify.php file which does the grunt work of the uploading, but I can never seem to access them. I obviously dont want to pass them to the uploadify.php script through the js because that will show my credentials in the source code. So, the question is, how can I access these session vars in the called file. I assume its a combination of session_write_end() and session_start() but I havent got the right combination yet. I have some function or method. Is there a better design patter to implement this?
function myFunction($a=null,$b=null,$c=null,$d=null,$e=null,$f=null,$g=null,$h=null)
{
//Do a bunch of stuff
}
Maybe the second function?
function myNewFunction($data=array())
{
$data=array_merge(array('a'=>null,'b'=>null,'c'=>null,'d'=>null,'e'=>null,'f'=>null,'g'=>null,'h'=>null),$array);
//Do a bunch of stuff
}
Please provide decision making factors why you would use one approach over the other.
