Orchard: Attaching a content part on-demand - orchardcms

I am working on a Forms Module which provides a FormPart. In the edit mode of this Part i've a listing of other ContentParts (those which implement a custom interface IForm). User can then choose one content part from the available list. The edit mode view of choosen Content Part should then be available underneath. If user changes his selection of content part the edit view should also reflect this change and load appropriate content part.
I know i can Weld Content Parts to content types using ContentHandlers but here the request has already been served and in Edit Mode view the user will specify what content part he wants to be welded.
Any suggestions or insights would be highly thankful.

If you look at the IContentDefinitionService in Orchard.ContentTypes there are several methods that you will probably find useful, primarily this one:
void AddPartToType(string partName, string typeName);
Use the source ;)

Kentico 10 - Web Part content change via database

i was trying to understand in the Kentico's database model how can i change the web parts content using a database script.
So, basically i have a website based on Kentico with several articles, and internal hyperlinks in its content. But the problem is that the format of those hyperlinks are actually invalid. And i was looking for a way to build a script and do a bulk-update in order to replace some characters and update those hyperlinks to the valid format.
Any idea how can i build the query to get the content of all web parts used in all published pages.
Thank you
It depends on your web parts and how the content is rendered. There are different ways that web parts render their content:
The web part layout is used for markup
The ASCX file for the web part is used for markup
The web part makes use of a repeater that uses a Transformation to render the markup- The markup is generated in code behind
The last one can be tricky to change depending on the web part and whether you have access to all the code behind, but the others you can change either in code in your solution or within the Administration area itself.
Doing this in SQL would probably require a combination of T-SQL XML support and regular expressions to find what you're looking for. you effectively need to look in the CMS_WebPart and CMS_WebPartLayout tables to find what you're looking for.
However, reading your query, I'm not 100% sure you're talking about web parts, (my apologies if you are) as you talk about links in the article content itself. If these are set using the Editable text web part, then you need to look in the CMS_Document table at the DocumentContent field to find the links to replace. But you then need to look at how to correctly format those links going forward so that you do not need to repeat this process later.
Note:
You need to be really careful when doing this in SQL to make sure that you don't create invalid XML. Things go bad when you do that.
This won't flush your cache, so you'll need to clear your cache manually afterwards.
If you're using out-of-the-box web parts, you should really make a copy of them and use the copy if you're going to modify, this way, you're less likely to have pain in future upgrades.
Typically "content" is not set in a webpart. Webparts are configured to retrieve content from page types. There is an exception to this with specific webparts like Editable Text, Static Text, Static HTML, etc.
The configuration of a webpart is stored at the template level in the cms_pagetemplate table. The configuration for ALL webparts on that page template are stored in the PageTemplateWebParts field. So you'd have to parse through the XML and get the proper webpart and then perform an update on that field. You maybe able to do a regex to find that content and replace it as well.
Not ideal to do this via SQL simply because of version history and it can cause a lot of problems later on. I'd suggest finding out which API calls you can make to perform these updates and write a small program for it.

Adding Duplicate Content Placeholders for Sharepoint 2013

I am working on our intranet that utilizes a custom .master page. One content placeholder that refers to the search functionality of SharePoint is being utilized in the footer ().
In our site mockup, we envisioned two search boxes, one in the top of the site, above the nav and one in the footer. I thought, easy, I just duplicate that content placeholder which brought up a duplication error from Sharepoint.
My question is this: Is there a way to duplicate content placeholders without needing to create a custom placeholder? And if not, is creating a custom placeholder the best way to go about this?
Thank you in advance!
There are many ways to customize this.
Direct master page change
Add (custom) place holder to master page
Use delegate controls (no master page change required)
Delegate controls allow you to create a regular user control (.ascx) and assign it a sequence number so that it becomes attached to an existing master page control. Using delegates could potentially allow you to attach the same user control to two different controls (delegates).
With all the recent "don't change the master page" buzz, it is becoming ever more relevant, although for on-premise scenarios, you can be a bit more eccentric.
Not only you can't duplicate place holders, but you should also be very careful while removing or even adding existing place holders, no matter how irrelevant they may appear to be. Even their original order matters (e.g. PlaceHolderPageTitleInTitleArea, PlaceHolderLeftNavBar).

Drupal how to add a search filter to admin content page

I've never used Drupal before (development or managing content). I was asked to extend the admin content page to have a filter and simply don't know enough to get moving quickly.
Can anyone tell me if adding a search by text filter in the admin content area requires code or is there a CMS feature like adding a node for this task.
If code is required, is there something like a hook for this area? Not sure where to start. I will be investigating on my own but pointers to get me oriented to Drupal would help.
By default Drupal provides search mechanism ready to use. But there are also additional module which can improve search experience. You don't need any coding to use that search. You already have search form block ready to use.
Go to Structure -> Blocks and find block called "Search form". Now all you have to do is to put that block in some region and it will appear on front-end. Of course if it's not already styled by your theme it may be needed to put some extra CSS to make it look nice. There are also some template files which you can override and put some your HTML if you need.
There's also template file for search results page (which of course will work out of box also).
You may also need to create new block region if you want to place your form at some specific place, not covered by any existing region defined by your theme (easy thing to do!).
See https://drupal.stackexchange.com/q/30633/101329, the "Admin Views" module lets you configure the search form as you like.

How to integrate a "shortcode" feature in Sharepoint wikis

I would like to "customize" my sharepoint wiki by doing something very simple.
I would like to be able to run a regex on wiki pages looking for [math] and [\math] tags, then take the expression written in the middle (assume this value is stored in a variable x) and replace the whole block by
"<img src='http://latex.codecogs.com/gif.latex?" + x +"'/>"
So for example, the shortcode [math]a^2+b^2=c^2[\math] should end up being displayed as an image as follows (thanks to this online tool):
I have never developed anything in sharepoint, and I've been using it for a week.
Can anybody tell me how I should proceed to add such a feature (if it's possible)?
You can use existing solution like ShortPoint.
Sure - this is simmply done via two methods - 1) You could modify the page directly using SharePoint designer - fly in the code where you want it, 2) The better way - add your code to text file, upload the text file to a document library then use the Content Editor web part, drop it on the page, point it (through the properties) to the text file.
Note: The Content Editor part will allow you to modify the background HTML/Script, however, it has a nasty habit of overriding your code and I've had it actually duplicate itself (adding repeat scripts). Using the Text file eliminiates that issue.
If i understand you correctly, I don't think that the content editor web part is the solution you are looking for. I believe you are wanting to implement a shortcodes solution such as that found in WordPress, correct? In that case, the issue becomes a bit more complex. To really get any kind of custom code that would execute at the necessary stages, you would need a custom solution either implementing additional functionality in the existing rich text editor, or roll your own custom rich text editor.
At that point, you would have complete control over how the content is parsed and interpreted, so you could have both server-side and client side processing. You could make use of templating engines like mustache or handlebars.
To do this, you would need to write your own Custom field type, inherit from SPFieldMultiLineText, override the property FieldRenderingControl, and return your custom control. That way you have the option of implementing it in several different places (custom pege fields in a page layout, custom webparts, custom lists, etc.) and you still get the benefits you want from the out-of-the-box control.

SharePoint SPContext.List in a custom application page

I have a custom SharePoint application page deployed to the _layouts folder. It's a custom "new form" for a custom content type. During my interactions with this page, I will need to add an item to my list. When the page first loads, I can use SPContext.Current.List to see the current list I'm working with. But after I fill in my form and the form posts back onto itself and IsPostBack is true, then SPContext.Current.List is null so I can't find the list that I need to add my stuff into.
Is this expected?
How should I retain some info about my context list across the postback? Should I just populate some asp:hidden control with my list's guid and then just pull it back from that on the postback? That seems safe, I guess.
FWIW, this is the MOSS 2007 Standard version.
Generally speaking I try and copy whatever approach the product group has taken when looking to add functionality of my own. In this case they add their own edit/view/add pages via the list definition itself.
I built a solution that also needed its own custom "New" form, not open source unfortunately, though if you are interested you can download it, its called "Tagged Links" (Social Bookmarking for SharePoint) and you can find some links on my blog.
To give you a few hints and tips, the following should set you off in the right direction:
Created a new list definition.
Created a new Content Type In the content type you can define your own "FormTemplates" that references a Rendering Template which determine what gets displayed in the "Middle" bit of those forms.
Copied the standard Rendering Template, but then made the changes to it that I
needed.
Wrapped it all up in a solution, and deployed.
My Rendering Template actually included an overridden "Save" Button where I did a lot of the extra work I needed to do during the save.
Anyway, it is a little too much work in my opinion but, I think, it most closely matches the standard approach taken by the product developers. Let me know if you need more detail and I will see if I can put together a step-by-step blog post, but hopefully this gets you off on the right direction.
I would be surprised if you could do something in a _Layouts file that you can't do in a forms template. You have pretty much the same technologies at your disposal.
Looking at the way SharePoint works with ListItems and Layouts pages (for example "Manage Permissions" on a list item), I can see that they pass some variables in via querystrings:
?obj={76113B3A-FABA-4389-BC85-4BB2CC5AB423},6,LISTITEM&List={76113B3A-FABA-4389-BC85-4BB2CC5AB423}
Perhaps they grab the context back each time programmatically using these values.
I'm not using a custom "new form", so this might not apply. I added an event receiver to my custom content type and then do my custom code in the ItemAdded or ItemAdding events. This code fires when the event is added to a list. You can use the event receiver properties to get to the parent List, Web, and Site.
I'd like to think my issue is "special" here, since I am using a custom form. I chose to use a custom form rather than a custom FormTemplate simply because I'm doing a lot of stuff that's not very SharePoint list-like (making ajax calls to get info from a third-party app then generating some dynamic form elements based on that ajax result, then subsequent processing of that data on postback). I thought it'd be a nightmare to try this within the usual custom rendering template mechanism.
I also don't think I can supply the custom form declarations in the list definition itself, because I have multiple content types associated with this list, and each content type has its own custom form (the other type is thankfully much simpler).
Actually, my simple way of keeping the list guid in my hidden field was a very low impact way to address this specific problem. My main concern is that I'm not sure why the SPContext just loses all its usefulness when I postback here, which makes me think I'm doing something wrong.
