Hello!

Okay, so here I found CI's db caching mechanisim, which essentially caches queries/results into file system
http://ellislab.com/codeigniter/user-gui...ching.html

And here, is info on MySQL's query cache mechanism, which caches queries/results into memory
http://dev.mysql.com/doc/refman/5.0/en/query-cache.html


Big Broad Questions
Which one is better?
Are they the same functionally?
Which is better for performance in single server environment?
MySQL's query cache can't cache SELECTS with RAND() for example, can CI's DB query cache?

Any other thing good to know? Thanks!

Hi,
Just started using CI - very nice
A totally default installation gives a warning of:

A PHP Error was encountered
Severity: Warning
Message: preg_match() expects parameter 2 to be string, array given
Filename: helpers/url_helper.php
Line Number: 93

when using the scaffolding.
Tracking back through the code I see the 'view' model in scaffolding uses :

<?php echo anchor(array($base_uri, 'edit', $row->$primary), $scaff_edit); ?>

Would it be useful to add 2 lines of code into the anchor() function in the URI helper as follows:

function anchor($uri = '', $title = '', $attributes = '')
{
if (is_array($uri))
$uri=implode('',$uri); // --EDIT-- :- or perhaps I meant implode on '/' ! I think I probably did
.... existing code ...
}

This would stop the warning message. I don't know if this would affect the code in ways I haven't thought about though !

Here's an example: http://citastic.com/multi-dimensional%20post%20data.mov

and here's the code..just replace your version, and everything works the way it's outlined in the user_guide: http://jtaby.com:82/svn_portal/trunk/sys...dation.php

Please let me know what you think, and if you find any bugs...enjoy!

I have created an application with all usual stuff like user login/logout and sessions.

I want to know , What is the best way to store the misc. user data ? , like

last logins , their fav page on website , bookmarks etc. without dealing too much with mysql. ( i dont want to create a table and/or field for every new thing i want to store).

first idea is to get a huge array storing all the data ,serialzie it and store it in text fields. but then, i need to retrieve the whole data , for even a simple small amount of data,that i needed to look for.

I want to know , what everybody else is doing ? , what is ideal thing from performance point of view ?


tell me if i haven't make myself clear.

Hi there. I'm a new user to both PHP and CI. I've gone through the tutorials and a couple of other CI tutorials that I've found.

So, I get stuck on all the forms tutorial for the dumbest reason. For some reason I cannot get a submit button to work. I get everything to display, I can fill things in, but when I click submit, nothing happens.

Hi!

I am building some kind of social networking website right now and I am having this dilema:

my urls look like this:

domain.com/browse/state/city/username

each username has a form on their page so people can send them message... i'm trying to set simple validations on each of the profile's pages...

Hey, I am just needing a bit of help with .htaccess/mod_rewrite and wanted to know how do I configure my webserver/.htaccess file so that instead of showing /index.php/mypage it will skip the index.php so your url would be http://yourpage.com/codeigniter/mypage.

Thanks in advance.

Hello, I'm very new to CI and quite new to MySQL, so I have no idea where this might be coming from. I did a search and found a few similar errors, but nothing that explained how I might fix it.

Basically, I wanted to use scaffolding to insert a few entries into my feeds table. I got this error:

I have a default controller set to products.

and i have this code for pagination:

I am converting a CMS I wrote to CI and am struggling a bit with how to implement the pre-existing language files I have for it.

Right the language files use a variable $lang_whatever for the various language words/phrases. It seems to work ok if I do a require(/path/to/language/file) within the function within the controller, but this would be very tedious to do throughout every controller and function. In addition, I am wanting the CMS to allow a default site language as well as allowing each user to select their language (which is stored in the database). So I'm not sure simply setting the $config['language'] and having the users upload to /system/application/lang/ is quite what I want to do. I am hoping to keep the CMS-specific language files as close to root level as possible.

I have searched through a lot of pages here and looked through the wiki trying to find an answer and I'm totally stumped. If someone could tell me how to do this or point me in the direction of the answer I would be forever grateful.

Thanks so much
