PHP - Php Curl - Multiple Independent Sessions - Need Help!
Here is my dilemma...
I basically have a script which by means of CURL posts to a 3rd party website to perform a login and then makes another post to update a users details based on that login session. Now as my site is getting busy I have multiple users doing the same thing and it seems that on occasion curl is getting confused and updating one users details with a different users information. This is causing real problems. It seems to be that the cookie which is being used by a user after one login is being shared by other users and they end up logging in with the same cookie - confusing the 3rd party system. My code is posted below and I need to use the cookiefile and cookiejar to maintain the php session to allow me to do what I need to do. But it seems like the same cookie is being reused by all users.... Does that make sense? Is there anything I can do to change this? Please advise.... Thanks so much! Below is the code i use to both login and post the user update function hitForm($postURL, $postFields, $referer="", $showerr = FALSE, $ispost = TRUE) { global $islocal, $path_escape; $ch = curl_init(); curl_setopt($ch, CURLOPT_COOKIEJAR, "cookies.txt"); curl_setopt($ch, CURLOPT_COOKIEFILE, "cookies.txt"); curl_setopt($ch, CURLOPT_URL, $postURL); if ($ispost) curl_setopt($ch, CURLOPT_POST, 1); else curl_setopt($ch, CURLOPT_HTTPGET, 1); curl_setopt($ch, CURLOPT_REFERER, $referer); curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.3) Gecko/2008092417 Firefox/3.0.3"); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_POSTFIELDS, $postFields); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE); $ret = curl_exec($ch); if ($error = curl_error($ch)) { if ($showerr) echo 'ERROR: ' . $error; return -1; exit; } $CU_header = curl_getinfo($ch); $CU_header["err"] = curl_errno($ch); $CU_header["errmsg"] = curl_error($ch); curl_close($ch); $returnout = $ret; //for debugging purposes for now we are logging all form posts SaveLog("hitform", "F[".$this->curruserid." - ".$this->currfunc." - ".date("d-m-y h:i:s")."]".$postFields); return $ret; } Similar Tutorialsgood day dear community, i am workin on a Curl loop to fetch multiple pages: i have some examples - and a question: Example: If we want to get information from 3 sites with CURL we can do it like so: $list[1] = "http://www.example1.com"; $list[2] = "ftp://example.com"; $list[3] = "http://www.example2.com"; After creating the list of links we should initialize the cURL multi handle and adding the cURL handles. $curlHandle = curl_multi_init(); for ($i = 1;$i <= 3; $i++) $curl[$i] = addHandle($curlHandle,$list[$i]); Now we should execute the cURL multi handle retrive the content from the sub handles that we added to the cURL multi handle. ExecHandle($curlHandle); for ($i = 1;$i <= 3; $i++) { $text[$i] = curl_multi_getcontent ($curl[$i]); echo $text[$i]; } In the end we should release the handles from the cURL multi handle by calling curl_multi_remove_handle and close the cURL multi handle! If we want to another Fetch of sites with cURL-Multi - since this is the most pretty way to do it! Well I am not sure bout the string concatenation. How to do it - Note I want to fetch several hundred pages: see the some details for this target-server sites - /(I have to create a loop over several hundred sites). * siteone.example/?show_subsite=9009 * siteone.example/?show_subsite=9742 * siteone.example/?show_subsite=9871 .... and so on and so forth Question: How to appy this loop into the array of the curl-multi? <?php /************************************\ * Multi interface in PHP with curl * * Requires PHP 5.0, Apache 2.0 and * * Curl * ************************************* * Writen By Cyborg 19671897 * * Bugfixed by Jeremy Ellman * \***********************************/ $urls = array( "siteone", "sitetwo", "sitethree" ); $mh = curl_multi_init(); foreach ($urls as $i => $url) { $conn[$i]=curl_init($url); curl_setopt($conn[$i],CURLOPT_RETURNTRANSFER,1);//return data as string curl_setopt($conn[$i],CURLOPT_FOLLOWLOCATION,1);//follow redirects curl_setopt($conn[$i],CURLOPT_MAXREDIRS,2);//maximum redirects curl_setopt($conn[$i],CURLOPT_CONNECTTIMEOUT,10);//timeout curl_multi_add_handle ($mh,$conn[$i]); } do { $n=curl_multi_exec($mh,$active); } while ($active); foreach ($urls as $i => $url) { $res[$i]=curl_multi_getcontent($conn[$i]); curl_multi_remove_handle($mh,$conn[$i]); curl_close($conn[$i]); } curl_multi_close($mh); print_r($res); ?> I look forward to your ideas. I'm am somewhat new to PHP and am trying to set up a website for my cousin's wedding. Her idea is to have the guests sign in with a user/pass that she provides, and once they sign in, they will be taken to a page that has their name on it (i.e. "Mr. and Mrs. So and So, you are invited...). I have come to the conclusion that I will need to make an image for each guest's name (she wants to use a font for their names that nobody will have on their computer) so what I need to know is: How do I link each user name to their own personalized webpage, where the image of their name on the next page will change based on what username is entered? I have been told to use Sessions (which I don't yet have in this code), but I'm clueless as to how to make that work for multiple users. Where do I put the coding, what does the coding look like, etc. Thanks in advance for any help! The php code I have right now is this (i'm sorry it's so long, I just don't want to leave anything out that might be important): Code: [Select] $LOGIN_INFORMATION = array( 'steve' => 'password', 'rick' => 'password', 'tom'=> 'password' ); // request login? true - show login and password boxes, false - password box only define('USE_USERNAME', true); // User will be redirected to this page after logout define('LOGOUT_URL', 'http://www.example.com/'); // time out after NN minutes of inactivity. Set to 0 to not timeout define('TIMEOUT_MINUTES', 0); // This parameter is only useful when TIMEOUT_MINUTES is not zero // true - timeout time from last activity, false - timeout time from login define('TIMEOUT_CHECK_ACTIVITY', true); ################################################################## # SETTINGS END ################################################################## /////////////////////////////////////////////////////// // do not change code below /////////////////////////////////////////////////////// // show usage example if(isset($_GET['help'])) { die('Include following code into every page you would like to protect, at the very beginning (first line):<br><?php include("' . str_replace('\\','\\\\',__FILE__) .

But I want to show a progress bar while downloading file from external server. My existing code shows progress bar but its not effective (ex. if i try to download two media file, one video and another audio, and video size is larger than audio size the audio finishes first and the progress bar shows 100% also suddenly it drops to 50% as the video is still downloading ). I mean it actually shows two progress and I need one. If I could get average percentage value of two progress that would be better. Any suggestion regarding this will be greatly appreciated. <?php

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($_SESSION['color']); break; } ?> sorry if my question is not clear, any help is appreciated Thank You, hi im new to php i am making shopping cart i made a session variable to add products in cart when i run it gives this warning Notice: Undefined index: cart in C:\wamp\www\cart\public\views\layouts\shop.php on line 15 Notice: Undefined index: total_items in C:\wamp\www\cart\public\views\layouts\shop.php on line 16 Notice: Undefined index: total_price in C:\wamp\www\cart\public\views\layouts\shop.php on line 17 but when i click on add to cart it add product price and quanitity kindly help me my shop.php code is <head> <title> Shopping Cart</title> <link href="stylesheets/cool_style.css" media="screen" rel="Stylesheet" type="text/css" /> </head> <body> <h1> products</h1> <div class="cart"> <p><b> Shopping Cart</b></p> print_r($_SESSION['cart']); echo $_SESSION['total_items']; echo number_format($_SESSION['total_price'],2); </div> <hr /> </body> </html> and my index file is where i set session variables are include('db_fns.php'); include("cart_functions.php"); session_start(); if(isset($_SEESION['cart'])) // if change this conditon if(!isset($_SEESION['cart'])) it gives not warning but does not //add products to the cart it does not do anything { $_SESSION['cart']=array(); $_SESSION['total_items']=0; $_SESSION['total_price']=0.00; } $view=empty($_GET['view'])?'index':$_GET['view']; $controller='shop'; switch ($view){ case "index"; $products = find_product(); break; case "add_to_cart"; $id=$_GET['id']; $add_item=add_to_cart($id); $_SESSION['total_items']=total_items($_SESSION['cart']); $_SESSION['total_price']=total_price($_SESSION['cart']); header('Location: index.php'); break; case "update_cart"; break; case "checkout"; break; } if change this conditon if(!isset($_SEESION['cart'])) it gives not warning file run correctly with no warning but does not add products to the cart and does not do anything kindly help me please 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? hello i am makeing a forum and to post a new thread it has to check if the user is logged in, so i log into my website and i go to the post new topic but it says im not logged in here is the new_topic.php and also the login.php new_topic.php <?php session_start();

Are these two variables the same? Hi, is two people or more sitting on the same local network and sharing the same public ip address will have the same session if they browse all of them into the same website or same php script that create session ?
Edited by Issam, 16 November 2014 - 05:18 PM. Basically I am trying to make a login with sessions but its just not working. Can someone look and see for any errors in what I wrote or snippet suggestions? <?php //Start session session_start(); //Include database connection details require_once('config.php'); //Array to store validation errors $errmsg_arr = array(); //Validation error flag $errflag = false; //Connect to mysql server $link = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD); if(!$link) { die('Failed to connect to server: ' . mysql_error()); } //Select database $db = mysql_select_db(DB_DATABASE); if(!$db) { die("Unable to select database"); } //Function to sanitize values received from the form.

I want a password protected administration section and I want to use sessions on the administration section. When I for example click on add post, I want it to log in and go to page addpost.php where I can enter my text. This is what I've done so far. I would like to know what I have done wrong and how I should do to accomplish what I have mentioned above. <?php session_start(); if(isset($_POST['btnLogin']) || isset($_POST['addpost'])){ $txtUserId = $_REQUEST['txtUserId']; $txtPassword = $_REQUEST['txtPassword']; if (isset($_POST['txtUserId']) && isset($_POST['txtPassword'])) { if ($_POST['txtUserId'] === 'admin' && $_POST['txtPassword'] === 'abc123') { //$_SESSION['basic_is_logged_in'] = true; echo "you are logged in"; } elseif (empty($txtUserId) || empty($txtPassword)) { echo "fill in username and password"; } elseif ($_POST['txtUserId'] != 'admin'){ echo "wrong username"; } elseif ($_POST['txtPassword'] != 'abc123'){ echo "wrong password"; } } } ?> <?php //if (!isset($_SESSION['basic_is_logged_in']) // || $_SESSION['basic_is_logged_in'] !== true) ?> <html> <head> <title>Main User Page</title> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> </head> <body> <form method="post" name="frmLogin" id="frmLogin" action="main.php"> <table width="400" border="1" align="center" cellpadding="2" cellspacing="2"> <tr> <td width="150">User Id</td> <td><input name="txtUserId" type="text" id="txtUserId"></td> </tr> <tr> <td width="150">Password</td> <td><input name="txtPassword" type="password" id="txtPassword"></td> </tr> <tr> <td><input type="submit" name="btnLogin" value="Login"></td> </tr> <tr> <td><input type="submit" name="addpost" value="add post" /></td> </tr> <tr> <td><input type="submit" name="showstat" value="Show visitors log" /></td> </tr> <tr> <td><input type="submit" name="blogg" value="To blog (logout)" /></td> </tr> </table> </form> </body> </html> i have an upload form and a posting form on the same page. when you upload a file it is uploaded to the server. what i am then trying to do is add the name of the file to $_SESSION['attachment'] so i can use it later. 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? Hi, I have been looking at this code for hours and I can't figure out why the product name and quantity aren't transferring from treats.php to checkOut.php. I realize checkOut.php is extremely long but if I could get some help I would really appreciate it. In case you would want the link, it 's http://auntievics.com/treats.php Hi all, If I have a list of session ids, is it possible to use this list to determine which session is no longer active? Seems like it should be do-able but can't find help on it so I'm kinda guessing its not! Thanks for any help, Michael i have two files in php both have the same code and the file is Code: [Select] <?php session_start(); $con = mysql_connect("l","root",""); // here localhost and password will be filled accordingly if (!$con) { die('Connection failu ' . mysql_error()); } mysql_select_db("student",$con); $fetch=mysql_query("SELECT * from student1") or die(mysql_error()); $row = mysql_fetch_array($fetch) or die(mysql_error()); sleep(10); echo "Name: ".$row[0]."</br>"; echo " Age: ".$row[1]."</br>"; echo " Address: ".$row[2]; mysql_close($con); ?> Now i have another file which has the same code as above except there is no sleep function used in it . Now when i run the file which is wothout sleep it displyas results in seconds however the file with sleep function takes it time. Now the problem is if i load the file woth sleep function first then its delayed nature is reflected in another file which is without sleep() i.e now the file without sleep is taking longer time to open. please explain all this and possible solution to this problem the other file is Code: [Select] <?php session_start(); $con = mysql_connect("localhost","root","instablogs"); if (!$con) { die('Connection failu ' . mysql_error()); } mysql_select_db("student",$con); $fetch=mysql_query("SELECT * from student1") or die(mysql_error()); $row = mysql_fetch_array($fetch) or die(mysql_error()); echo "Name: ".$row[0]."</br>"; echo " Age: ".$row[1]."</br>"; echo " Address: ".$row[2]."</br>"; mysql_close($con); ?> 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! 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 |
