  • How do I keep users from spoofing data through a form?

    - by Jonathan
    I have a site which has been running for some time now that uses a great deal of user input to build the site. Naturally there are dozens of forms on the site. When building the site, I often used hidden form fields to pass data back to the server so that I know which record to update. an example might be: <input type="hidden" name="id" value="132" /> <input type="text" name="total_price" value="15.02" /> When the form is submitted, these values get passed to the server and I update the records based on the data passed (i.e. the price of record 132 would get changed to 15.02). I recently found out that you can change the attributes and values via something as simple as firebug. So...I open firebug and change the id value to "155" and the price value to "0.00" and then submit the form. Viola! I view product number 155 on the site and it now says that it's $0.00. This concerns me. How can I know which record to update without either a query string (easily modified) or a hidden input element passing the id to the server? And if there's no better way (I've seen literally thousands of websites that pass the data this way), then how would I make it so that if a user changes these values, the data on the server side is not executed (or something similar to solve the issue)? I've thought about encrypting the id and then decrypting it on the other side, but that still doesn't protect me from someone changing it and just happening to get something that matches another id in the database. I've also thought about cookies, but I've heard that those can be manipulated as well. Any ideas? This seems like a HUGE security risk to me.

  • Reason to use more cookies than just a session hash for authentication?

    - by dierre
    I usually hang out in a community using vBulletin as its bulletin board. I was looking at what this software saves as cookie in my browser. As you can see it saves 6 cookies. Amongst them, what I consider to be important for authentification are: ngivbsessionhash: hash of the current session ngivbpassword: hash of the password ngivbuserid: user's id Those are my assumptions of course. I don't know for sure if ngilastactivity and ngilastvisit are used for the same reason. My question is: why use all these cookie for authentication? My guess would be that maybe generating a session hash would be to easy so using the hashedpassword and userid adds security but what about cookie spoofing? I'm basically leaving on the client all fundamental informations. What do you think?

  • How to show / debug PEAR::DB errors in webpage?

    - by Markus Ossi
    I am connecting to MySQL database on my webpage and have this copy-pasted code for errors: if(DB::isError($db)) die($db->getMessage()); I have the connection code in an outside file called connection.inc that I include at the beginning of my page before the DOCTYPE and html tags. For debugging purposes, how can I print the database errors on my webpage? I thought I could do something like this: echo 'Could not connect to database. The error was:' . $db->getMessage(); but this returns: Fatal error: Call to undefined method DB_mysql::getMessage()

  • Is there a way to implement an XMPP client or message reciever that can recieve all the messages fro

    - by roberto
    Basically im trying to build a bot that can send a message using one of many accounts out to a user and be able to receive messages to that account it originally used process and do whatever I need it to do. So far I found the JAXL library (http://code.google.com/p/jaxl/) but based on examples it is only able to handle one user at a time. Any suggestions or ideas? thank you in advanced. btw if there is anyway to make the server automatically forward those messages to another program or whatever that works just as well.

  • How to remove characters from a string?

    - by masato-san
    Hi, Below is interview question so you cannot relay on the functions that predefined in libraries. Also my answer below set the element to null but there is another ways to solve the problem. Given string $string = "This is a pen", remove "is" so that return value is "Th a pen" (including whitespece). I've tried (shown below) but returned value is not correct. Thanks in advance! function remove_delimiter_from_string(&$string, $del) { for($i=0; $i<strlen($string); $i++) { for($j=0; $j<strlen($del); $j++) { if($string[$i] == $del[$j]) { $string[$i] = $string[$i+$j]; //this grabs delimiter :( } } } echo $string . "\n"; }

  • what persistence layer (xml or mysql) should i use for this xml data?

    - by fayer
    i wonder how i could store a xml structure in a persistence layer. cause the relational data looks like: <entity id="1000070"> <name>apple</name> <entities> <entity id="7002870"> <name>mac</name> <entities> <entity id="7002907"> <name>leopard</name> <entities> <entity id="7024080"> <name>safari</name> </entity> <entity id="7024701"> <name>finder</name> </entity> </entities> </entity> </entities> </entity> <entity id="7024080"> <name>iphone</name> <entities> <entity id="7024080"> <name>3g</name> </entity> <entity id="7024701"> <name>3gs</name> </entity> </entities> </entity> <entity id="7024080"> <name>ipad</name> </entity> </entities> </entity> as you can see, it has no static structure but a dynamical one. mac got 2 descendant levels while iphone got 1 and ipad got 0. i wonder how i could store this data the best way? what are my options. cause it seems impossible to store it in a mysql database due to this dynamical structure. is the only way to store it as a xml file then? is the speed of getting information (xpath/xquery/simplexml) from a xml file worse or greater than from mysql? what are the pros and cons? do i have other options? is storing information in xml files, suited for a lot of users accessing it at the same time? would be great with feedbacks!! thanks! EDIT: now i noticed that i could use something called xml database to store xml data. could someone shed a light on this issue? cause apparently its not as simple as just store data in a xml file?

  • Error 100 When Attempting to post from app to Facebook wall?

    - by IMAPC
    I'm playing around with the Facebook API, and have gotten far enough to get the access token into my app, but when I go to actually send a post to my Facebook wall I get the error message, {"error":{"message":"(#100) You can't post this because it has a blocked link.","type":"OAuthException","code":100}}1 I'm not attempting to send any kind of link, just "Hello, World!" so this seems pretty weird to me :\ Here's my code so far: $content = urlencode("Hello, World!"); $accesstoken = urlencode($row['fbid']); $result = getPageWithPOST("https://graph.facebook.com/me/feed", "access_token=" . $accesstoken . "&message=" . $content); echo $result; where getPageWithPOST is, function getPageWithPOST($url, $posts) { $c = curl_init(); curl_setopt($c, CURLOPT_URL, $url); curl_setopt($c, CURLOPT_POST, true); curl_setopt($c, CURLOPT_POSTFIELDS, $posts); $content = curl_exec ($c); curl_close ($c); return $content; } thanks!

  • How can I concatenate two mp3 files with different bit rates

    - by Scott
    I have FFmpeg installed on my linux web server. When I execute the following code, I have intermittent results. I think I have figured out that the MP3s do not compile when they have different bitrates. exec ('cat '. $pair['source_file'] . ' ' . $pair['translated_word_file'] . '>' . $temp_mp3); I might have found some articles online that reference taking them apart and then bundling them back together at a consistent bitrates. I have confirmed that this won't really work with basic "cat" function and that "sox" can be used IF they have the same sample rate. The issue now becomes "What is the best way to get them to the same sample rate?"

  • In CakePHP, how to leave all prefixes?

    - by Victor Piousbox
    I have a link that goes like this: $this->Html->link('Welcome', array('controller' => 'users', 'action' => 'add')); I suspect it doesn't work (Firefox says the redirect will never complete), so I did this: $this->Html->link('Welcome', array('controller' => 'users', 'action' => 'add', 'my'=>false)); 'my' is a prefix. I also have 'admin', 'ajax', and 'rss'. So now instead of pointing to /users/add or /my/users/add, the link points to /rss/users/add. The link is in a header, in a layout so I don't know which prefix it will be invoked from. I want to go to /users/add, that is, leave all prefixes altogether. How do I do that in CakePHP? I'm using 1.3 version.

  • More elegant way to parse inline variables in strings

    - by Tom
    Currently I have this: function parse_string($string, $variables){ extract($variables); return eval('return "'. addcslashes($string, '"') .'";'); } So I can input this string: 'Hi {$name}, my name is {$own_name}' Together with this array: array('name' => 'John', 'own_name' => 'Tom') And get this back: 'Hi John, my name is Tom'   I've never liked this eval() approach but it works and it's fast (faster than regex at least). Question: Is there a more elegant way to do this (faster than using regex) in PHP5?

  • Recommended/Standard image thumbnails sizes

    - by Rakan
    Hello, Based on my experience in web development, HTML page designs for every website may have different < img tags showing the same image in different sizes. i.e: the website's main page might show the image in 500*500, the listing page might show it in 200*150 and other sections of the website will use different sizes. As you can see the ratios of the images to be displayed to the user are different and therefore will cause a problem in having the image stretched, pixelated and/or other quality problems. How i currently handle this issue is by using a jQuery cropping tool to make the user select the area to crop the thumbnail from. the cropped image is then resized using imagick to fit every position in the page design. However, although i can force the user to crop an image based on a pre-defined ratio, the HTML will still contain image placeholders which require a different ratio for its thumbnail. So for every image, i will have to force the user to crop the uploaded image based on every possible ratio my site requires. I don't think this is a friendly solution, how would you do it? is there a standard/recommended ratio for the web? Thanks

  • Selenium: How to click an HTML button element?

    - by Andrew
    I have button on the page that being used as a link to another page. So when the user clicks the button they are redirected to the right page. I am using the Selenium extension for PHPUnit and I would like to test that the button is correctly redirecting the user. Here is the HTML that I am trying to test: <button onclick="window.location='/sponsor';" value="Continue" type="button" id="sponsorContinue" name="sponsorContinue">Continue</button> I have tried a lot of different approaches to click the button, but I can't seem to get any of them to work: $this->click("//button[@id='sponsorContinue']"); This command executes and does not throw any errors, but the page isn't redirected. It works fine when I manually click the button. What should I do?

This is what I have... <ul> {foreach from=$gallery key=index item=image} <li> <img src="{$image}" alt="" id="panel-{$index++}" /> </li> {/foreach} </ul> It doesn't work. Is the best way to do this to pre-process the array before handing it to Smarty? Is there a way I can do this using Smarty?
