  • PHP / MYSQL: Sanitizing user input - is this a bad idea?

    - by Greg
    I have one "go" script that fetches any other script requested and this is what I wrote to sanitize user input: foreach ($_REQUEST as $key => $value){ if (get_magic_quotes_gpc()) $_REQUEST[$key] = mysql_real_escape_string(stripslashes($value)); else $_REQUEST[$key] = mysql_real_escape_string($value); } I haven't seen anyone else use this approach. Is there any reason not to? EDIT - amended for to work for arrays: function mysql_escape($thing) { if (is_array($thing)) { $escaped = array(); foreach ($thing as $key => $value) { $escaped[$key] = mysql_escape($value); } return $escaped; } // else if (get_magic_quotes_gpc()) $thing = stripslashes($thing); return mysql_real_escape_string($thing); } foreach ($_REQUEST as $key => $value){ $_REQUEST[$key] = mysql_escape($value); }

  • Is it better to echo javascript in raw format with php, or echo a script include that has been minif

    - by Scarface
    Hey guys quick question, I am currently echoing a lot of javascript that is based conditionally on login status and other variables. I was wondering if it would be better to simply echo the script include like <script type="text/javascript" src="javascript/openlogin.js"></script> that has been run through a minifying program and been gzipped or to echo the full script in raw format. The latter suggestion is messier to me but it reduces http requests while the latter would probably be smaller but take more cpu? Just wondering what some other people think. Thanks in advance for any advice.

  • What risks are there in using extracted PHP superglobals?

    - by Zephiro
    Hola usando estas funciones, que riesgo corro en tener problemas de seguridad, es necesesario usar extract() o hay alguna manera mejor de convertir las variables superglobales (array) en trozos de variables. Good, there is some risk in using the function extract in the superglobal variables as $_POS and $_GET, I work of the following way. There is risk of SQL INJECTION or there is an alternative to extract if ( get_magic_quotes_gpc() ) { $_GET = stripslashes( $_GET ); $_POST =stripslashes( $_POST ); } function vars_globals($value = '') { if (is_array ( $value )) $r = &$value; else parse_str ( $value, $r ); return $r; } $r = vars_globals( $_GET ); extract($r, EXTR_SKIP);

  • Have to login twice. PHP sessions and login troubles with Chrome and Opera.

    - by Robert
    The problem I am encountering is that for my login form I have to login twice for the session to register properly, but only in Chrome (my version is 4.0.249.89) and Opera (my version is 10.10). Here is the stripped down code that I am testing on: Login Page: session_start(); $_SESSION['user_id'] = 8; $_SESSION['user_name'] = 'Jim'; session_write_close(); header('Location: http://www.my-domain-name.com/'); exit(); Home Page: session_start(); if ( isset($_SESSION['user_id']) ) { echo "You are logged in!"; } else { echo "You are NOT logged in!"; } Logout Page: session_start(); session_unset(); session_destroy(); header('Location: http://www.my-domain-name.com/'); exit(); Currently, under a fresh load with no cookies, if I go to my-domain-name.com/login/ it will redirect to the home page and say "You are NOT logged in!" but if I go there again it will say "You are logged in!". Any ideas? Thanks for your help.

  • PHP Arrays: Loop trough array with a lot of conditional statements. Help / Best practices

    - by Jonathan
    Hi, I have a problem I don't know how to get it to work the best way. I need to loop trough an array like the one below. I need to check if the [country] index is equal to a Spanish speaking country (lot of countries) and then get those [title] indexes of the correspondent country and check for duplicates. The original array: Array ( [0] => Array ( [title] => Jeux de pouvoir [country] => France ) [1] => Array ( [title] => Los secretos del poder [country] => Argentina ) [2] => Array ( [title] => Los secretos del poder [country] => Mexico ) [3] => Array ( [title] => El poder secreto [country] => Uruguay ) ) To help you understand, the final result I need to get looks something like this: Array ( [0] => Array ( [title] => Los secretos del poder [country] => Argetnina, Mexico ) [1] => Array ( [title] => El poder secreto [country] => Uruguay ) )

  • setting default value of superglobal

    - by Prasoon Saurav
    I have been working on a Timesheet Management website. I have my home page as index.php //index.php <?php session_start(); if($_SESSION['logged']=='set') { $x=$_SESSION['username']; echo '<div align="right">'; echo 'Welcome ' .$x.'<br/>'; echo'<a href="logout.php" class="links">&nbsp;<b><u>Logout</u></b></a>' ; } else if($_SESSION['logged']='unset') { echo'<form id="searchform" method="post" action="processing.php"> <div> <div align="right"> Username&nbsp;<input type="text" name="username" id="s" size="15" value="" /> &nbsp;Password&nbsp;<input type="password" name="pass" id="s" size="15" value="" /> <input type="submit" name="submit" value="submit" /> </div> <br /> </div> </form> '; } ?> The problem I am facing is that during the first run of this script I get an error Notice: Undefined index: logged in C:\wamp\www\ps\index.php but after refreshing the page the error vanishes. How can I correct this problem? logged is a variable which helps determine whether the user is logged in or not. When the user is logged in $_SESSION['logged'] is set, otherwise unset. I want the default value of $_SESSION['logged'] to be unset prior to the execution of the script. How can I solve this problem?

  • How to remove one instance of one string in PHP?

    - by Jane
    I have a open source editor on the cms that I am making that automatically inserts a <br /> tag at the beginning of the post it submits to the database. This makes validation a pain, since even though there is no real text being submitted, the form still accepts the break tag as input and prevents the "Please enter some text" error from showing. So I tried to remove the opening break tag by filtering my input like this: substr($_POST['content'], 6); This works as long as the user doesn't press the backspace a couple of times which removes the break tag in which case the first 8 characters of the post gets removed even if they are not a break tag. So how can I remove the first 6 characters of the input ONLY if those first 6 characters are composed of the break tag. Also I don't want to remove all break tags, only the one at the very beginning of the post.

  • PHP / Zend Framework: Force prepend table name to column name in result array?

    - by Brian Lacy
    I am using Zend_Db_Select currently to retrieve hierarchical data from several joined tables. I need to be able to convert this easily into an array. Short of using a switch statement and listing out all the columns individually in order to sort the data, my thought was that if I could get the table names auto-prepended to the keys in the result array, that would solve my problem. So considering the following (assembled) SQL: SELECT user.*, contact.* FROM user INNER JOIN contact ON contact.user_id = user.user_id I would normally get a result array like this: [username] => 'bob', [contact_id] => 5, [user_id] => 2, [firstname] => 'bob', [lastname] => 'larsen' But instead I want this: [user.user_id] => 2, [user.username] => 'bob', [contact.contact_id] => 5, [contact.firstname] => 'bob', [contact.lastname] => 'larsen' Does anyone have an idea how to achieve this? Thanks!

  • PHP, what is the better choice for removing a known string?

    - by Brook Julias
    I am looking to search for and replace a known string from within another string. Should I use str_replace() or ereg_replace()? The string to be replaced would be something similar to [+qStr+], [+bqID+], or [+aID+] and it would be being searched for in a code chunk similar to this: <li> [+qStr+] <ol class="mcAlpha"> <li><input type="radio" name="[+bqID+]" id="[+bqID+]_[+aID+]" value="[+aID+]" /><label for="[+bqID+]_[+aID+]">[+aStr+]</label></li> </ol> </li> I would be replacing the strings with the results from a MySQL query, and be performing this action or similar up to 200 times at a time. Which function str_replace() or ereg_replace() would be the easiest and/or quickest method to take.

  • php - Can I integrate functions with same content, different names?

    - by Gal
    I have a couple of functions inside a class that essentially do the same thing: public function fn_a(){ return __FUNCTION__; } public function fn_b(){ return __FUNCTION__; } public function fn_c(){ return __FUNCTION__; } I need those functions to remain in their current names so I intentionally did not do: public function fn_($letter){ return __FUNCTION__.$letter; } I was hoping for some sort of way to minify the verboseness of code here, since they all do the same. The ultimate situation would be something like this: public functions fn_a, fn_b, fn_c() { return __FUNCTION__; } Another solution, if applicable, might be doing something like Class's "extends": fn_b, fn_c extend fn_a? What do you think guys?
