I am now familiar with "basic" Typo3 - Usage and templating. Right now, I am stuck though, because I am not familiar with custom extensions etc.
I am looking for a way to represent Objects, that I get via methods of my own php-class from an XML-DB-Interface, in Typo3.
To be more precise :
I have a really complex XML-Interface and a php-class which is complete already, to interact with that interface, making methods available, that are meant to interact with different object-types in the underlying DB.
I now want to create abstract objects with the corresponding attributes in Typo3 to be able to work with them in typo3 (display/create/modify).
Furthermore, it would be helpful to find a way to "link" the functions of my php class to typo3-functions, so I can (perhaps?!) build up some kind of simple report-generator that generates conditional reports of those objects.
Could anybody lead me into the right direction and link (a) HowTo(s) or perhaps even examples that I could modify?
Thanks in advance, Oliver
Check how DBAL extension is coded.

You might want to implement this XML system as your own abstraction system to store your objects and use TYPO3 backend forms to manipulate those.

Just like TImageList contains a collection of images, is there a similar component for generic files?
I know I can embed files as resources, but I'd like the convenience of storing different groups of files in different "TFileList" components, and to be able to retrieve files by name or by their position in the list.
Extra points if such a component allowed some sort of design time preview of the file content (just like TImageList lets you see what each image looks like, at design time).
(I come from Delphi where I wrote my own component to do the above, but before I rewrite and port the property editor and all that to Lazarus, maybe there is already something that is tried and tested...)
Thanks!
You can use pre-defined lazarus TFPGList to specialize list of the type, that you want, for example - UTF8String
But, there's no T<>List as a component, only as object.
So, yes, this feature will be useful and i can implement, if have time,
also, there's a very limited RTTI, which has been updated only a few months ago, so you can access Methods and Properties now, so FP is more systemized, than delphi pascal, but also not so enterprise-developed, which limits it to implementations for common opensource and shareware project problems.
Nevertheless, it is more stable and supported, even my friends can contribute.
I'm working on an Orchard site where I want to document some code - a series of plugins and a set of commands that each plugin can handle.
So I'd like to have a page for each plugin, and a page for each available command, then somehow link the plugins with their supported commands.
On the plugin page, I'd like to have a list of all the commands supported by that plugin.
Conversely, on the page where each command is documented, I'd like to list all the plugins that support it. This seems to be a many-to-many relationship.
I'm happy with creating content types and I guess I'll create a 'Plugin' content type and a 'Command' content type. I expect the solution will somehow involve the use of queries. I'm not really sure how to tie it all together though.
I'm not really sure how to approach this. Has anyone got any suggestions for how to achieve this? Is there a way to do this just by configuration and defining new content types, or do you think I'll need to write code?
You can either use a content picker field configured for multiple items, or you can implement it following this doc topic: http://docs.orchardproject.net/Documentation/Creating-1-n-and-n-n-relations
One option is to us the Mechanics Module, which gives you a way to create relationships between parts either in your data migration or using the admin UI. See the Mechanics Documentation to find out more.
I'm relatively new to Expression Engine, and as I'm learning it I am seeing some stuff missing that WordPress has had for a while. A big one for me is shortcodes, since I will use these to allow CMS users to place more complex content in place with their other content.
I'm not seeing any real equivalent to this in EE, apart from a forthcoming plugin that's in private beta.
As an initial test I'm attempting to fake shortcodes by using delimited strings (e.g. #foo#) in the content field, then using a regex to pull those out and pass them to a function that can retrieve the content out of EE's database.
This brings me to a second question, which is that in looking at EE's API docs, there doesn't appear to be a simple means of retrieving the channel entries programmatically (thinking of something akin to WP's built-in get_posts function).
So my questions are:
a) Can this be done?
b) If so, is my method of approaching it reasonable? Or is there something stupidly obvious I'm missing in my approach?
To reiterate, my main objective here is to have some means of allowing people managing content to drop a code in place in their content that will be replaced with channel content.
Thanks for any advice or help you can give me.
Here's a simple example of the functionality you're looking for.
1) Start by installing Low Replace.
2) Create two Global Variables called gv_hello and gv_goodbye with the values "Hello" and "Goodbye" respectively.
3) Put this text into the body of an entry:
[say_hello]
Nice to see you.
[say_goodbye]
4) Put this into your template, wrapping the Low Replace tag around your body field.
{exp:low_replace
find="[say_hello]|[say_goodbye]"
replace="{gv_hello}|{gv_goodbye}"
multiple="yes"
}
{body}
{/exp:low_replace}
5) It should output this into your browser:
Hello
Nice to see you.
Goodbye
Obviously, this is a really simple example. You can put full blown HTML into your global variable. For example, we've used that to render a complex, interactive graphic that isn't editable but can be easily dropped into a page by any editor.
Unfortunately, due to parse order issues, EE tags won't work inside Global Variables. If you need EE tags in your short code output, you'll need to use Low Variables addon instead of Global Variables.
Continued from the comment:
Do you have examples of the kind of shortcodes you want to support/include? Because i have doubts if controlling the page-layout from a text-field or wysiwyg-field is the way to go.
If you want editors to be able to adjust layout or show/hide extra parts on the page, giving them access to some extra fields in the channel, is (imo) much more manageable and future-proof. For instance some selectfields, a relationship (or playa) field, or a matrix, to let them choose which parts to include/exclude on a page, or which entry from another channel to pull content from.
As said in the comment: i totally understand if you want to replace some #foo# tags with images or data from another field (see other answers: nsm-transplant, low_replace). But, giving an editor access to shortcodes and picking them out, is like writing a template-engine to generate ee-template code for the ee-template-engine.
Using some custom fields to let editors pick and choose parts to embed is, i think, much more manageable.
That being said, you could make a plugin to parse the shortcodes from a textareas content, and then program a lot, to fetch data from other modules you want to support. For channel entries you could build out of the channel data library by objectiveHTML. https://github.com/objectivehtml/Channel-Data
I hear you, I too miss shortcodes from WP -- though the reason they work so easily there is the ubiquity of the_content(). With the great flexibility of EE comes fewer blanket solutions.
I'd suggest looking at NSM Transplant. It should fit the bill for you.
There is also a plugin called Shortcode, which you can find here at
Devot-ee
A quote from the page:
Shortcode aims to allow for more dynamic use of content by authors and
editors, allowing for injection of reusable bits of content or even
whole pieces of functionality into any field in EE
I'm building an iPhone app that, among other things, allows the user to take and store photographs associated with locations. I am currently using the ALAssetLibrary to allow the photographs to be stored in Photos and be accessible outside the app (on a computer for instance via the built-in mechanisms). There is not a lot of technical content out there for working with the ALAssetLibrary but from what there is I have managed to cobble together a working version of this. I have had to resort to storing a dictionary of photo URLS in my app and manually detecting if the photo still exists when displaying lists of them because there does not seem to be a way to add custom metadata to an ALAsset.
What I would really like to do is add two custom metadata fields to each asset to provide it with a title and a custom id value that I can use to filter on when enumerating the asset library.
As a secondary task, I'd like the user to be able to update the title metadata.
Can it be done? At this point, I really don't think it can because the API really doesn't seem to provide the necessary methods to get/set custom metadata. I'm hoping against all odds that there is some other aspect to the AssetLibrary framework that I have not yet discovered.
At a minimum, if someone can authoritatively say "NO" then at least others might find this breadcrumb on their own trail of hope and change tack more quickly!
And, having 0 reputation I can't tag it with AssetLibrary :( wow, this day is just going downhill. FML
I've been looking over the documentation and I dont think it is possible to tack on additional fields to the ALAsset object, well you can create your own object or extend theirs but that wont help you when your pulling back assets because you'll need to init yours and populate it then.
Look I know this falls short of a really good answer but I had to try.
The ALAsset class documentation describes a property - customMetadata. This is documented to be an NSDictionary of whatever custom tags you want. Currently, however, it is not implemented in the class (I've raised a bug on Apple's developer site to bring the issue up).
I want to add a calendar control to a page that already includes Prototype and Scriptaculous. Not happy with any of the Prototype ones I could find, I'm considring using the YUI Calendar widget.
I this likely to cause any problems?
We have worked hard to make sure that YUI is safe to use with any other library. We namespace everything, as HermanD says, under only one required global (YAHOO) and one optional one (YAHOO_config). We don't modify native objects. And even though Protoype does modify native prototypes, we code defensively so that this doesn't break YUI functionality.
If you find any bugs in using the two together, please let us know.
Regards,
Eric
YUI Team
By default everything in YUI is within the YAHOO namespace, so as long as you sensibly apply namespaces to anything you use from YUI, I would have thought you should be ok.
See: http://developer.yahoo.com/yui/yahoo/
I successfully used the YUI tab control in an app I was already using Prototype and Scriptaculous in and had no problem. The weight of all that is a bit much though if you're looking at a publicly available app. I wouldn't care so much about an internal app, say for a company, but you might want to think about how much JavaScript you're making end users download and the number of separate files they're having to download for the page.
