  • Sanitizing user input that will later be e-mailed - what should I be worried about?

    - by Kevin Burke
    I'm interning for an NGO in India (Seva Mandir, http://sevamandir.org) and trying to fix their broken "subscribe to newsletter" box. Because the staff isn't very sophisticated and our web host isn't great, I decided to send the relevant data to the publications person via mail() instead of storing it in a MySQL database. I know that it's best to treat user input as malicious, and I've searched the SO forums for posts relevant to escaping user data for sending in a mail message. I know the data should be escaped; what should I be worried about and what's the best way to sanitize the input before emailing it? Form flow: 1. User enters email on homepage and clicks Submit 2. User enters name, address, more information on second page (bad usability, I know, but my boss asked me to) and clicks "Submit" 3. Collect the data via $_POST and email it to the publications editor (and possibly send a confirmation to the subscriber). I am going to sanitize the email in step 2 and the other data in step 3. I appreciate your help, Kevin

  • WordPress get_post_count?

    - by Scott B
    I'd like to create a function that retrieves the post count for a given query. I don't want to use get_posts obviously as its way to expensive for this purpose. However, that's exactly what I'm having to use in absense of a get_post_count function. My code is... global $post; $cat=get_cat_ID('mymenu'); $catHidden=get_cat_ID('hidden'); $myrecentposts = get_posts(array('post_not_in' => get_option('sticky_posts'), 'cat' => "-$cat,-$catHidden",'showposts' => $NumberOfPostsToShow)); $myrecentposts2 = get_posts(array('post_not_in' => get_option('sticky_posts'), 'cat' => "-$cat,-$catHidden",'showposts' => -1)); $myrecentpostscount = count($myrecentposts2);

  • Looking for design/architecture suggestions for a simple HTML game.

    - by z-boss
    Imagine that HTML page is a game surface (see picture). User can have n number of boards (blue divs) on his page. Each board can be moved, re-sized, relabeled, created new and removed. Inside each board there are m number of figures (purple divs). Each of these user can move inside the board or to another board, re-size, change color and label, delete, add new. The goal of the game is not important, but let's say it is to rearrange figures in a certain way so that they disappear. But the goal of the programmer is to save the whole game surface in the database for every user of the site, and to load it later when he returns. So, how do I go about data exchange between client and the database? I'll give my idea in one of the answers.

  • Inserting Newline from XML to Database

    - by blackmage
    I am trying to parse this xml document in which a newline is required for certain fields and must be inserted into the database with the newline. But I've been running into problems. 1)First Problem: \n Character The first problem I had was using the \n like below. <javascript>jquery_ui.js\nshadowbox_modal.js\nuser_profile.js\ntablesorter.js</javascript> The problem was in the database the field came out ot be jquery_ui.js\nshadowbox_modal.js\n... and when output into html it was jquery_ui.jsnshadowbox_modal.jsn............... 2) Then I tried actually having newlines in the xml <javascript>jquery_ui.js shadowbox_modal.js user_profile.js tablesorter.js</javascript> The problem was the output become %20%20%20%20%20%20%20%20%20%20shadowbox_modal.js, and so forth. So how can I get a newline to hold from xml when entered into a database and then output with the newline still?

  • Drupal 6 dynamic menu item

    - by djeux
    I need to create a menu item, which changes its title and link if a user has a certain condition, or not. Drupal caches all the menues, so i can't really think of a way to do that. For example, user has a node attached to his profile, menu item is "Create blabla" (link node/add/blabla) User doesn't have the node, menu item is "Create notblablabla" (link node/add/notblabla)

    - by nightingale2k1

I know there are Gavick, it is good ... but I need second options for that 2. thumbnail image for each articles. Joomla has no thumbnail for article modules .. sad :( 3. comment system. should I use Disqus (disqus.com) or using jomcomment. About Disqus, is it good and reliable services ? 4. Tag hierarchy ... any good recommendations ? 5. I hate Joomla Media Manager and Joomla Text Editor (TinyMCE) because I cannot choose directly from media manager (i have to type the full url for images). Any good recommendations ?

  • Are these two functions overkill for sanitization?

    - by jpjp
    function sanitizeString($var) { $var = stripslashes($var); $var = htmlentities($var); $var = strip_tags($var); return $var; } function sanitizeMySQL($var) { $var = mysql_real_escape_string($var); $var = sanitizeString($var); return $var; } I got these two functions from a book and the author says that by using these two, I can be extra safe against XSS(the first function) and sql injections(2nd func). Are all those necessary? Also for sanitizing, I use prepared statements to prevent sql injections. I would use it like this: $variable = sanitizeString($_POST['user_input']); $variable = sanitizeMySQL($_POST['user_input']);

  • Masspay and MySql

    - by Mike
    Hi, I am testing Paypal's masspay using their 'MassPay NVP example' and I having difficulty trying to amend the code so inputs data from my MySql database. Basically I have user table in MySql which contains email address, status of payment (paid,unpaid) and balance. CREATE TABLE `users` ( `user_id` int(10) unsigned NOT NULL auto_increment, `email` varchar(100) collate latin1_general_ci NOT NULL, `status` enum('unpaid','paid') collate latin1_general_ci NOT NULL default 'unpaid', `balance` int(10) NOT NULL default '0', PRIMARY KEY (`user_id`) ) ENGINE=MyISAM AUTO_INCREMENT=6 DEFAULT CHARSET=latin1 COLLATE=latin1_general_ci Data : 1 [email protected] paid 100 2 [email protected] unpaid 11 3 [email protected] unpaid 20 4 [email protected] unpaid 1 5 [email protected] unpaid 20 6 [email protected] unpaid 15 I then have created a query which selects users with an unpaid balance of $10 and above : $conn = db_connect(); $query=$conn->query("SELECT * from users WHERE balance >='10' AND status = ('unpaid')"); What I would like to is for each record returned from the query for it to populate the code below: Now the code which I believe I need to amend is as follows: for($i = 0; $i < 3; $i++) { $receiverData = array( 'receiverEmail' => "[email protected]", 'amount' => "example_amount",); $receiversArray[$i] = $receiverData; } However I just can't get it to work, I have tried using mysqli_fetch_array and then replaced "[email protected]" with $row['email'] and "example_amount" with row['balance'] in various methods of coding but it doesn't work. Also I need it to loop to however many rows that were retrieved from the query as <3 in the for loop above. So the end result I am looking for is for the $nvpStr string to pass with something like this: $nvpStr = "&EMAILSUBJECT=test&RECEIVERTYPE=EmailAddress&CURRENCYCODE=USD&[email protected]&L_Amt=11&[email protected]&L_Amt=11&[email protected]&L_Amt=20&[email protected]&L_Amt=20&[email protected]&L_Amt=15"; Thanks

  • Regexp: Replace only in specific context

    - by blinry
    In a text, I would like to replace all occurrences of $word by [$word]($word) (to create a link in Markdown), but only if it is not already in a link. Example: [$word homepage](http://w00tw00t.org) should not become [[$word]($word) homepage](http://w00tw00t.org). Thus, I need to check whether $word is somewhere between [ and ] and only replace if it's not the case. Can you think of a preg_replace command for this?

  • Is SPLFileObject atomic?

    - by Jakub Lédl
    I'm wondering whether methods of PHPs SPLFileObject are atomic (e.g. thread-safe) or not? If they aren't, I'll implement my own class, which will use flock(), but is this enough? Is the flock function really thread-safe? What if the collision occurs after I fopen() the file, but before I flock() it?

  • Smarty html_options

    - by SeanJA
    For smarty's html_options function, is there a way to avoid having to do this (other than not using smarty that is)? {if $smarty.post} {html_options name=option_1 optins=$options selected=$smarty.post.option_1} {else} {html_options name=option_1 optins=$options} {/if} I realize that it won't show up in the template, but it seems like a bad practice to leave something that is not defined in the template (it also fills up my error logs with noise about undefined indexes).

  • How to generate Doctrine models/classes that extend a custom record class

    - by Shane O'Grady
    When I use Doctrine to generate classes from Yaml/db each Base class (which includes the table definition) extends the Doctrine_Record class. Since my app uses a master and (multiple) slave db servers I need to be able to make the Base classes extend my custom record class to force writes to go to the master db server (as described here). However if I change the base class manually I lose it again when I regenerate my classes from Yaml/db using Doctrine. I need to find a way of telling Doctrine to extend my own Base class, or find a different solution to a master/slave db setup using Doctrine. Example generated model: abstract class My_Base_User extends Doctrine_Record { However I need it to be automatically generated as: abstract class My_Base_User extends My_Record { I am using Doctrine 1.2.1 in a new Zend Framework 1.9.6 application if it makes any difference.

  • Kohana 3 ORM - grouping where conditions with parentheses

    - by Greelmo
    I'm trying to run a query through the ORM like this: SELECT * from table where (fname like 'string%' or lname like 'string%') AND (fname like 'string2%' or lname like 'string2%'); Here's what i have so far: $results = ORM::factory('profiles'); foreach ($strings as $string) { $result->where('fname', 'like', "$string%"); $result->or_where('lname', 'like', "$string%"); } But this doesn't account for the parentheses. Any ideas?

  • Magento Set Grid to Filter Automatically by Current Day using Existing Datetime Column in Grid

    - by Tegan Snyder
    In Magento I'm creating a custom module and would love to be able to filter automatically by the datetime column so that the intial grid listing shows only entities related to "todays" date. Here is my datetime column: $this->addColumn('ts', array( 'header' => $hlp->__('Activated'), 'align' => 'left', 'index' => 'ts', 'type' => 'datetime', 'width' => '160px', )); I'm think there should be a way for me to just add a filter to the collection like so: $now = Mage::getModel('core/date')->timestamp(time()); $dateTime = date('m/d/y h:i:s', $now); $collection = Mage::getModel('mymodule/items')->getCollection() ->addFieldToFilter('ts', $dateTime); But this doesn't work? Am I using the wrong filter? My "ts" field in the database is a "datetime" field, but the default magento "From: " - "To:" date range selectors don't use hours, minutes, seconds. Any ideas? Thanks, Tegan

  • Counting multiple entries in a MySQL database?

    - by Aaron
    Hi all, I'm trying to count multiple entries in a MySQL database, I know how to use COUNT(), but the exact syntax I want to get the results I need eludes me. The problem: Table structure: ID, CODE, AUTHOR, COUNTRY, TIMESTAMP. Code, Author and Country overlap many times in the table. I am trying to discover if there is one simple query that can be ran to return (using WHERE clause on COUNTRY) the author field, the code field, and then a final field that counts the number of times the CODE was present in the query result. So, theoretically I could end up with an array like: array('author', 'code', 'codeAppearsNTimes'); Authors also have varying codes associated with them, so I don't want the results merged. I suppose the end result would be: 'This author is associated with this code this many times'. Is this possible with MySQL? Thanks in advance.

  • HTTP vs FTP upload

    - by Richard Knop
    I am building a large website where members will be allowed to upload content (images, videos) up to 20MB of size (maybe a little less like 15MB, we haven't settled on a final upload limit yet but it will be somewhere between 10-25MB). My question is, should I go with HTTP or FTP upload in this case. Bear in mind that 80-90% of uploads will be smaller size like cca 1-3MB but from time to time some members will also want to upload large files (10MB+). Is HTTP uploading reliable enough for such large files or should I go with FTP? Is there a noticeable speed difference between HTTP and FTP while uploading files? I am asking because I'm using Zend Framework which already has HTTP adapter for file uploads, in case I choose FTP I would have to write my own adapter for it. Thanks!

  • Zend Sessions problem with IE8

    - by Emil
    I'm running a Zend Framework powered website and it seems to have serious problems with sessions. I have a 5 step process where I save the form data in the session between the steps and then save it into the database on the last step. When we built the site sometimes the session just went away and forced us to restart. Now it seems to work again but recently we discovered an issue with Internet Explorer 8. It fails between step 2 - 3 and forgets the session. It works fine in IE6, IE7, FF, Chrome, Safari and even in my mobile web browser (SE P1). We're storing our sessions in the database and if I deactivate the session db handler it works. What's the difference between using the database and not using it for sessions? Do I loose something if I switch back? Bootstrap: /* Start session */ $saveHandler = new Zend_Session_SaveHandler_DbTable(array( 'name' => 'sessions', 'primary' => 'id', 'modifiedColumn' => 'modified', 'dataColumn' => 'data', 'lifetimeColumn' => 'lifetime' )); Zend_Session::rememberMe((int) $config->session->lifetime); $saveHandler->setLifetime((int) $config->session->lifetime) ->setOverrideLifetime(true); Zend_Session::setSaveHandler($saveHandler); Zend_Session::start(); and in my step controller $session = new Zend_Session_Namespace('wizard'); Then I'm just working with $session saving data in a stdClass in $session.

  • How to automatically read in calculated values with PHPExcel?

    - by Edward Tanguay
    I have the following Excel file: I read it in by looping over every cell and getting the value with getCell(...)->getValue(): $highestColumnAsLetters = $this->objPHPExcel->setActiveSheetIndex(0)->getHighestColumn(); //e.g. 'AK' $highestRowNumber = $this->objPHPExcel->setActiveSheetIndex(0)->getHighestRow(); $highestColumnAsLetters++; for ($row = 1; $row < $highestRowNumber + 1; $row++) { $dataset = array(); for ($columnAsLetters = 'A'; $columnAsLetters != $highestColumnAsLetters; $columnAsLetters++) { $dataset[] = $this->objPHPExcel->setActiveSheetIndex(0)->getCell($columnAsLetters.$row)->getValue(); if ($row == 1) { $this->column_names[] = $columnAsLetters; } } $this->datasets[] = $dataset; } However, although it reads in the data fine, it reads in the calculations literally: I understand from discussions like this one that I can use getCalculatedValue() for calculated cells. The problem is that in the Excel sheets I am importing, I do not know beforehand which cells are calculated and which are not. Is there a way for me to read in the value of a cell in a way that automatically gets the value if it has a simple value and gets the result of the calculation if it is a calculation? Answer: It turns out that getCalculatedValue() works for all cells, makes me wonder why this isn't the default for getValue() since I would think one would usually want the value of the calculations instead of the equations themselves, in any case this works: ...->getCell($columnAsLetters.$row)->getCalculatedValue();
