• What would I use to remove escaped html from large sets of data.

  - by Elizabeth Buckwalter

  Our database is filled with articles retrieved from RSS feeds. I was unsure of what data I would be getting, and how much filtering was already setup (WP-O-Matic Wordpress plugin using the SimplePie library). This plugin does some basic encoding before insertion using Wordpress's built in post insert function which also does some filtering. I've figured out most of the filters before insertion, but now I have whacko data that I need to remove. This is an example of whacko data that I have data in one field which the content I want in the front, but this part removed which is at the end: <img src="http://feeds.feedburner.com/~ff/SoundOnTheSound?i=xFxEpT2Add0:xFbIkwGc-fk:V_sGLiPBpWU" border="0"></img> <img src="http://feeds.feedburner.com/~ff/SoundOnTheSound?d=qj6IDK7rITs" border="0"></img> &lt;img src=&quot;http://feeds.feedburner.com/~ff/SoundOnTheSound?i=xFxEpT2Add0:xFbIkwGc-fk:D7DqB2pKExk&quot; Notice how some of the images are escape and some aren't. I believe this has to do with the last part being cut off so as to be unrecognizable as an html tag, which then caused it to be html endcoded. Another field has only this which is now filtered before insertion, but I have to get rid of the others: &lt;img src=&quot;http://farm3.static.flickr.com/2183/2289902369_1d95bcdb85.jpg&quot; alt=&quot;post_img&quot; width=&quot;80&quot; (all examples are on one line, but broken up for readability) Question: What is the best way to work with the above escaped html (or portion of an html tag)? I can do it in Perl, PHP, SQL, Ruby, and even Python. I believe Perl to be the best at text parsing, so that's why I used the Perl tag. And PHP times out on large database operations, so that's pretty much out unless I wanted to do batch processing and what not. PS One of the nice things about using Wordpress's insert post function, is that if you use php's strip_tags function to strip out all html, insert post function will insert <p> at the paragraph points. Let me know if there's anything more that I can answer. Some article that didn't quite answer my questions. (http://stackoverflow.com/questions/2016751/remove-text-from-within-a-database-text-field) (http://stackoverflow.com/questions/462831/regular-expression-to-escape-html-ampersands-while-respecting-cdata)

• Php date() giving the wrong time after parsing

  - by Kirill

  This is confusing as hell, here's the php I'm using: <?php echo date('H:i D j, F',$j->date); ?> This is what it gives me: 01:33 Thu 1, January Which seems fine, until you look at the actual time that is being given ($j-date provides): 2010-06-12 21:12:23 Why is it giving me a January and what am I doing wrong?

• Insert coding query in yii

  - by nerd

  I need to auto insert the next orders_id into an Orders table in a database. orders_id is not the primary Key, and it does not auto-increment I need to query the database, find the last (highest) id value, increment 1, and insert it in Orders table in database. Actually, I have a shipping action which will provide address of shipping of orders. So as soon as the user fills address form and move to payments page, I want to simultaneously fill my Orders table by max(orders_id)+1. I have built relations between Address table and Orders table but my orders Table is not getting populated. Please detail me correct codes to implement it in my controller in Yii

• 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.

• Should I include user_id in multiple tables?

  - by Drarok

  I'm at the planning stages of a multi-user application where each user will only have access their own data. There'll be a few tables that relate to each other, so I could use JOINs to ensure they're accessing only their data, but should I include user_id in each table? Would this be faster? It would certainly make some of the queries easier in the long run. Thanks!

• SQL Query in Ruby: Only select the changes

  - by JJ Liu

  Suppose I have a table (PriceHistory) like this, every time I change anything in the row, I will record the whole row again in the table. id | buy_price | sell_price | change_date 1 | 2 | 2 | 2012-06-22 2 | 3 | 2 | 2012-06-20 3 | 2 | 6 | 2012-06-15 4 | 5 | 5 | 2012-06-15 5 | 5 | 7 | 2012-06-15 6 | 4 | 8 | 2012-06-12 I only care about the change of BuyPrice, Is there a way to just select row 1, 2, 3, & 5? Here is the Ruby code I come up with, but it does not only select the changed rows PriceHistory.select("id, BuyPrice, change_date"). order("change_date DESC") Both Ruby and SQL answers are fine.

• how relate one table to another for future records

  - by Sinan

  I have a games table which holds the data about a game. Then another table which holds the data about news. So far so good. First I thought about creating a junction table for game_news so I could relate news to games. This way works as intended when the game exists. So whenever I insert a news I can relate it to a game using the junction table. However there are cases when there is news about game but the game isn't published and it doesn't exists. So my question would be; is there a way to relate these news to a particular game when the game record is created. What is the best way to do this? Any ideas?

• PHP: How To Integrate HTML Purifier To Fileter User Submitted Data?

  - by TaG

  I have this script that collects data from users and I wanted to check their data for malicious code like XSS and SQL injections by using HTML Purifier http://htmlpurifier.org/ but how do I add it to my php form submission script?

• How to make a Round Robin? or Is there an easier way other than Round Robin?

  - by candies

  The problem that I face is in what way if there is issue like the example below: Codes 1000, 2000, 3000, 4000, 5000 ID 1, 2, 3 ======================================== This: ID number 1 has codes 1000, 2000, 3000, 4000 ID number 2 has codes 2000, 4000, 3000 ID number 3 has codes 3000, 4000, 5000 ======================================== When all the fields are connected, each ID has found the same codes. From the example above, I want to produce fair result and adjusted to the code that it had before on each ID as below: ======================================== To be: ID number 1 has codes 1000, 2000 (1000 must be on number 1 cause only it has than other) ID number 2 has codes 3000, 4000 ID number 3 has codes 5000 (5000 must be on number 3 cause only it has than other) ======================================== Some say using Round Robin, but I never heard Round Robin before and I don't have idea how to use it, such a blank mind. Is there another easier way like to use PHP may be? I'm lost. Thanks.

• Modifying my website to allow anonymous comments

  - by David

  I write the code for my own website as an educational/fun exercise. Right now part of the website is a blog (like every other site out there :-/) which supports the usual basic blog features, including commenting on posts. But I only have comments enabled for logged-in users; I want to alter the code to allow anonymous comments - that is, I want to allow people to post comments without first creating a user account on my site, although there will still be some sort of authentication involved to prevent spam. Question: what information should I save for anonymous comments? I'm thinking at least display name and email address (for displaying a Gravatar), and probably website URL because I eventually want to accept OpenID as well, but would anything else make sense? Other question: how should I modify the database to store this information? The schema I have for the comment table is currently comment_id smallint(5) // The unique comment ID post_id smallint(5) // The ID of the post the comment was made on user_id smallint(5) // The ID of the user account who made the comment comment_subject varchar(128) comment_date timestamp comment_text text Should I add additional fields for name, email address, etc. to the comment table? (seems like a bad idea) Create a new "anonymous users" table? (and if so, how to keep anonymous user ids from conflicting with regular user ids) Or create fake user accounts for anonymous users in my existing users table? Part of what's making this tricky is that if someone tries to post an anonymous comment using an email address (or OpenID) that's already associated with an account on my site, I'd like to catch that and prompt them to log in.

• How to implement filter system in SQL?

  - by sadvaw

  Right now I am planning to add a filter system to my site. Examples: (ID=apple, COLOR=red, TASTE=sweet, ORIGIN=US) (ID=mango, COLOR=yellow, TASTE=sweet, ORIGIN=MEXICO) (ID=banana, COLOR=yellow, TASTE=bitter-sweet, ORIGIN=US) so now I am interested in doing the following: SELECT ID FROM thisTable WHERE COLOR='yellow' AND TASTE='SWEET' But my problem is I am doing this for multiple categories in my site, and the columns are NOT consistent. (like if the table is for handphones, then it will be BRAND, 3G-ENABLED, PRICE, COLOR, WAVELENGTH, etc) how could I design a general schema that allows this? Right now I am planning on doing: table(ID, KEY, VALUE) This allows arbitary number of columns, but for the query, I am using SELECT ID FROM table WHERE (KEY=X1 AND VALUE=V1) AND (KEY=X2 AND VALUE=V2), .. which returns an empty set. Can someone recommend a good solution to this? Note that the number of columns WILL change regularly

• many-to-many query

  - by kofto4ka

  Hello, guys! I have a problem and I dont know what is better solution. Okay, I have 2 tables: posts(id, title), posts_tags(post_id, tag_id). I have next task: must select posts with tags ids for example 4, 10 and 11. Not exactly, post could have any other tags at the same time. So, how I could do it more optimized? Creating temporary table in each query? Or may be some kind of stored procedure? In the future, user could ask script to select posts with any count of tags (it could be 1 tag only or 10 at the same time) and I must be sure that method that I will choose would be the best method for my problem. Sorry for my english, thx for attention.

• Improving the speed of php

  - by cast01

  I'm currently working on a website in PHP, and I'm wondering what the best practices/methods are to reduce the time requests take. I've build the site in a modular way, so a page would consist of a number of modules, and each of these would need to request information. For example, I have a cart module, that (if a cart is set) will fetch the cart with the id (stored in a session variable) from the database and return its contents. I have another module that lists categories and this needs to fetch the categories from the database. My system is built with models, and each model might also make a request, for example a category model will make a request to get products in that category.

Does the CREATE_TABLE field change automatically for Innodb tables?
