Folders-like URL with PHP?

- by Maxime

Hi, ever since I added this htaccess to my website, I noticed a HUGE slowdown, and my error logs are filled with errors such as PHP Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL result resource in page.php on line 79. I've got up to four of these per second. Most of the time it works though. The htaccess consisted of two similar rules: one with two GET vars, another one with only one. RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)\/(.*)$ index.php?var1=$1&var2=$2 [L] Anyway, I just rewrote a PHP script that handles of all the strings and redirects where it should, and my website is now fast again. But is there a way to hide mypage.php?var1=la&var2=lu and still have URLs that look like folders? Thanks for your replies!

Pros and cons of sorting data in DB?

- by Roman

Let's assume I have a table with field of type VARCHAR. And I need to get data from that table sorted alphabetically by that field. What is the best way (for performance): add sort by field to the SQL-query or sort the data when it's already fetched? I'm using Java (with Hibernate), but I can't tell anything about DB engine. It could be any popular relational database (like MySQL or MS Sql Server or Oracle or HSQL DB or any other). The amount of records in table can vary greatly but let's assume there are 5k records.

Datagrid for Symfony?

- by Stick it to THE MAN

I want to use a datagrid in one of my modules (Symfony 1.3, Propel ORM). I have spent a while searching the web, but everything I found expects a direct connection to teh db (mySQL) or is otherwise unsuitable. I found the datagrid plugin (http://symfony.swisscenter.com/datagrid/exemples), but the documentation/examples are in French - and I'm not too keen on learning French just for the sake of using the plugin - besides, if all the users are French speakers, then it will be difficult to get support/help if/when I do hget stuck. So my questions are: Is anyone aware of a good (PHP) datagrid component that I can use with SF? Is anyone out there (English speaker), using the SF datagrid plugin?

Cakephp with OpenID and User Authentication

- by nolandark

I have a table "users" and I want to enable my visitors to login with their openID Account. For this I use the OpenId Component for Cakephp and it works fine (When I login with the Google URL I receive the "successfully authenticated!" notification). But now I'm kind of stuck because I don't know how to go on from there. Do I have to create a User-Entry for every user which has a new entry in the "oid_associations" table (I save all OpenId interaction in the mysql database)? Do I have to authenticate the User after the login (or is the OpenID-component doing that automatically?). Am I completely misunderstanding the concept?

mysqli and field types

- by Mikk

Hi, I'd like to know if there is a simple way to fetch data from mysql tables with "correct" data types? What i mean, if field type is for example INT or SMALLINT is it possible to pass those types directly to PHP as integers? I did some searching and found mysqli_fetch_fields, but for SMALLIT type is 2, for INT 3 and so on. It could be done that way, but it looks rather clumsy workaround. Is there any better way? I'm using PHP and mysqli. Thank you.

What is a good approach for a Data Access Layer?

- by Adil Mughal

Our software is a customized Human Resource Management System (HRMS) using ASP.NET with Oracle as the database and now we are actually moving to make it a product that supports multiple tenants with their own databases. Our options: Use NHibernate to support Multiple databases and use of OO. But we concern related to NHibernate learning curve and any problem we faced. Make a generalized DAL which will continue working with Oracle using stored procedures and use tools to convert it to other databases such as SQL Server or MySql. There is a risk associated with having to support multiple database-dependent versions of a single script. Provide the software as a Service (SaaS) and maintain the way we conduct business. However there can may be clients who do not want or trust the Cloud or other SaaS business models. With this in mind, what's the best Data access layer technique?

How to organise a php based website

- by bsandrabr

I am putting my php /mysql website up and this is my scenario The users are grouped into sites each site with their own unique database. There will be about 40 users per site. the two options I'm trying to decide between are have a central website running the php and directing the users off to their own database using sub domains for each user each with their own php in htdocs I dont even know if 2 is possible/stupid but if it was, would it make any difference to performance as they're all being run by the same server. Any other ideas/ advice much appreciated as I want to organise it the best way from the start

Creating standalone, console (shell) for domain-specific operations

- by mr.b

Say that I have a system service, and I want to offer a low-level maintenance access to it. For that purpose, I'd like to create a standalone, console application that somehow connects to server process and lets user type in commands, allow it to use auto-completion and auto-suggestion on single/double TAB press (just like linux bash shell, mysql cli, cmd.exe, and countless others), allow command line editing capabilities (history, cursor keys to move around text..), etc. Now, it's not that much of a problem to create something like that by rolling my own from scratch, handling user input, scanning pressed keys, and doing correct actions. But, why reinvent the wheel? Is there some library/framework that helps with this kind of problems, just like readline library that offers improved command-line editing capabilities under linux? Of course, this new "shell" would respond only to valid, domain-specific commands, and would suggest valid arguments, options, switches... Any ideas? Thanks!

Sqlite and Python -- return a dictionary using fetchone()?

- by AndrewO

I'm using sqlite3 in python 2.5. I've created a table that looks like this: create table votes ( bill text, senator_id text, vote text) I'm accessing it with something like this: v_cur.execute("select * from votes") row = v_cur.fetchone() bill = row[0] senator_id = row[1] vote = row[2] What I'd like to be able to do is have fetchone (or some other method) return a dictionary, rather than a list, so that I can refer to the field by name rather than position. For example: bill = row['bill'] senator_id = row['senator_id'] vote = row['vote'] I know you can do this with MySQL, but does anyone know how to do it with SQLite? Thanks!!!

PHP doesn't show any kind of errors

- by iSenne

Hello everybody I have a PHP server at home for development. It is running: Ubuntu 9.10 Apache 2.2.12 PHP 5.3.2-0.dotdeb.1 MySql 5.0.7-dev Currently the settings in the php.ini for displayiong errors are: display_errors = on error_reporting = E_ALL But I do not see any errors in my php script. Also very strange is that phpinfo() shows me this: display_errors Off I checked the php.ini file, and restarted the apache server many times, but with no luck. Does anybody knows how this is possible? edit: When I localy set this: ini_set('display_errors', 'on'); I do receive errors.

Building html tables from query data... faster?

- by Andrew Heath

With my limited experience/knowledge I am using the following structure to generate HTML tables on the fly from MySQL queries: $c = 0; $t = count($results); $table = '<table>'; while ($c < $t) { $table .= "<tr><td>$results[0]</td><td>$results[1]</td> (etc etc) </tr>"; ++$c; } $table .= '</table>'; this works, obviously. But for tables with 300+ rows there is a noticeable delay in pageload while the script builds the table. Currently the maximum results list is only about 1,100 rows, and the wait isn't long, but there's clearly a wait. Are there other methods for outputting an HTML table that are faster than my WHILE loop? (PHP only please...)

how do i supply data to my gwt tree

- by molleman

Hello, So i need to create a tree with tree items for my gwt project. i am using the composite pattern to store all the information i need to be placed within a tree.

Trouble i am having is building my tree based on this pattern. this data is all stored using hibernate in a mysql database How would i be able to implement this as a tree in gwt. Also the tree item that i create would have to reference back to the object so i can rename or move it.

problem with doctrine:build-schema

- by Ying

Hi, im using symfony with doctrine, and Im trying to generate the schema yml file from a db. I get an this error SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'group' at line 1. Failing Query: "DESCRIBE group"I have a table named group in my database, and I suspect that this is screwing it up. Its not access problems as ive checked my db previleges. Any suggestions on what I can do? I have tried the quote-identifier attribute but with no luck : ( Im also struggling to find some good doctrine documentation. i cant seem to find where a list of attributes are, say for a creating a column in the schema.yml file. I tried reaching out to symfony forums but they are not responsive! Any help would be greatly appreciated! Thanks..

asp.net free webcontrol to display matrix reports with column and row grouping, subtotals and totals

- by dev-cu

Hello, I want to develop some kind of reports in Asp.net with x-axis and y-axis being dynamics, allowing grouping by row and column, for example: have products in y-axis and date in x-axis having in body number of sells of a given product in a given date, if date in x-axis are years, i want subtotals for each month for a product (row) and subtotals of sells of all products in date (column) I know there are products available to build reports, but i am using Mysql, so Reporting Service is not an option. It's not necessary for the client build additional reports, i think the simplest solution is having a control to display such information and not using crystal report (which is not free) or something more complex, i want to know if is there an available free control to reach my goal. Well, does anybody know a control or have a different idea, thanks in advance.

Hi gusy, I just installed XAMPP, Apache is running, so is MySQL and Mercury.

Thanks! R

How to deal with 'bad' decision forced on you regarding basic software for your product

- by raticulin

Here is my situation, our product used to support several of the major databases. Now management has decided to move all products to MaxDB (aka SapDB previously), and even if we keep supporting some of the previous dbs, all new installations are on MaxDB. I am sure MaxDB is a great db and can support huge SAP installations. But from the point of view of a software developper, its a nightmare. Every time you need to do something not trivial (write an stored procedure, some fancy trigger...) and you google for some info, you get like 0.1% of the hits you would with things like MySql, PostgreSql or MSSql. Mailing lists are nearly non existant. SAP does support it commercially but it is not clear wether we'll buy support. And the decision cannot be rolled back. The product works with MaxDB, but with lots of inefficiency on development and a lot of frustration, is there something one could do?

PHPIniDir broken under windows 7?

- by bobbyb

I had a server running on a windows xp machine using apache2 with php and mysql. I've recently upgraded to windows 7 and have been having trouble getting it to work. Apache works fine and php works, but I can't seem to get it to work with a php.ini file. When I set PHPIniDir to a directory with a php.ini file, the Apache service does NOT start. When I set PHPIniDir to a directory with NO php.ini file, the Apache service does start. When I leave out PHPIniDir, the Apache service does not start. Has anyone found a fix for this problem? Thanks! EDIT: PHPIniDir "C:\Windows" #works (no php.ini file) PHPIniDir "C:\Program Files (x86)\php\" #does not work (contains php.ini file) i enable at most one at any given time.

What some good PHP jobs?

- by ggfan

I am no professional PHP coder or anything, in fact I am fairly new. I can develop sites but nothing too crazy or fancy with PHP,Mysql,CSS,HTML,javascript. Up to now, all I have been doing is practice coding from books and websites. I am now looking for a 'real-life' experience. Besides going to a company and getting an interview, are there any other options in which I can get paid to code? I have posted some ads on craiglists but that's about it. And because this is my first time going to the 'real-word' and can make mistakes, am I liable if...a site I made for someone gets hacked and that person losses information?

Facelets charset problem

- by Vladimir

Hi! In my earlier post there was a problem with JSF charset handling, but also the other part of the problem was MySQL connection parameters for inserting data into db. The problem was solved. But, I migrated the same application from JSP to facelets and the same problem happened again. Characters from input fields are replaced when inserting to database (c is replaced with Ä), but data inserted into db from sql scripts with proper charset are displayed correctly. I'm still using registered filter and page templates are used with head meta tag as following: <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-2"> If I insert into h:form tag the following attribute: acceptcharset="iso-8859-2" I get correct characters in Firefox, but not in IE7. Is there anything else I should do to make it work? Thanks in advance.

What XSS/CSRF attacks (if any) to be aware of when allowing video embeds?

- by fireeyedboy

I've been assigned a project for a website where users will be allowed to upload video's (using a YouTube API) but more importantly (for me) they will also be allowed to submit video embed codes (from numerous video sites, YouTube, Vimeo, etc. etc.). Having no experience with allowing users to embed video: How can I best protect against cross site scripting and/or cross site request forgery attacks specifically for video embedding? What are some of the common pitfalls to watch for? At a minumum I would think to strip all tags except <object> and <embed>. But I have a feeling this will not be enough, will it? If it is of importance, the environment will be: PHP/Zend Framework MySQL Bonuspoints: Is there a common minimum golden rule/code template for video embed codes that are valid across all video sites that I could use to filter the input?

A PHP object server for business logic

- by Matthieu

I wonder if such a thing is possible or even exist : In the MVC pattern, I would like to have the Model part to be persistant in memory, instead of reloading my instances at each execution. So I want only the Controller and View part to be executed. Is there any solution of server that would provide PHP objects (just like a Mysql server provides data records), and that keeps these objects in memory ? A problem would be also : how to have a constructed query to get objects ? Maybe PHP Linq ?

Whats the best solution for a database used in conjunction with Maps in Android?

- by Andrew

Could someone please point me in the right direction. My project involves a database where users enter their address and other info from my website. This database is then referenced in my android application to show the locations of these addresses in my database. I have yet to start and just came up with this idea. My question is, what would be the best method to create a database easily modified through my website (mySQL, php, etc), and also easily referenced easily through Android and the Google Maps API? I need some ideas on the languages I will need to use to create this database and website so I can go buy the necessary books to start reading up. Thanks so much
