I have PAGENAME
For example PAGE: iPad
I need two parameters for this page:
Parameter PRICE: $999
Parameter AVAILABLE: Available, Not available
How can I get there parameters on page?
I would like to be able to get, in addition than {{PAGENAME}}, parameters on the page ?
And where could I store a lot of these parameters?
For example:
iPad1 — $999 — Available
iPad2 — $1999 — Available
iPad3 — $2999 — Not available
iPad4 — $3999 — Available
iPad5 — $2999 — Not available
etc.
How is it edit more comfortable for a lot of parameters?
I work on the Pixel Dungeon Wiki a lot and it has a Data template which can be used to store information about an item.
To use it, copy the template over then create a page called ipad/data.
Then add to ipad/data:
{{Data|{{{1|}}}|{{{2|}}}|{{{3|}}}|{{{4|}}}|{{{$|}}}
| iPad1price = $999
| iPad1available = AVAILABLE
| iPad2price = $1999
| iPad2available = AVAILABLE
...
}}
Then you can access the information on the page with:
iPad1 price is {{:ipad/data||iPad1price}}
The Data template documentation is quite good for more info on this

I am starting to work with Vowpal Wabbit with Python and I am kinda struggling with its lack of documentation.
Do you guys know what modeling it uses as a cost/reward estimation for each arm? Do you know how to retrieve this current estimation?
vw = pyvw.vw("--cb_explore 2 --epsilon 0.2")
input = "2:-20:0.5 | Anna"
vw.learn(initial_input)
input = "1:-10:0.1 | Anna"
vw.learn(initial_input)
vw.predict(" | Anna")
Output would be:
[0.10000000149011612, 0.9000000357627869]
How can I also get the expected value for each arm? Something like
[-10.00, -20.00]
When using _explore you get back a PMF over the given actions. This is true for CB and CB_adf.
However, when using the non-explore version for each of those things differ a bit.
--cb is going to give you the chosen action directly, whereas --cb_adf is going to return the score for each given action.
So in this situation changing to using action dependent features (ADF) should provide the score/estimated cost.
Is it possible to have predefined values on a template? I.e.
{{Infobox Employee
|age = {{{age}}}
|gender = {male,female}
|occupation = {nurse, doctor, caretaker}
}}
So whenever someone uses this template they have to chose either male or female and if neither is chosen nothing shows. Very much like a select in html.
In core MediaWiki, you can make the template output an error or ignore unexpected parameters but cannot prevent the user from entering an invalid value. E.g. you can do something like this in the infobox:
{{#switch:{{{gender}}}
| male = Male
| female = Female
| #default = <span style="color:red">Invalid gender</span>[[Category:Pages with invalid template parameters]]
}}
(This example uses #switch from the ParserFunctions extension. You can do the same thing without ParserFunctions but it requires some complex and awkward template code.)
With the TemplateData extension you can specify allowed values, but it will only affect editors which rely on TemplateData (e.g. VisualEditor); it won't influence what someone can do with the template by plaintext editing.
The Semantic Forms extension can display an actual form for editing the infobox, with select boxes and whatever else you specify.
Folks,
I'd like to have similar set up to the one discussed in this question
Can I use templates to form a set of variables that I can then later include in various points in my wiki pages.
so for example have varables in my single template called MAIN_WEB_URL and MAIN_TEAM_DISTRIBUTION_LIST that I can store in a single template and reference site-wide where needed.
I'd like to avoid a template per variable if possible, but the other question seems to imply this is the only way to do it...
One way to do this would be to create a template called something like Template:Variable. In it, you would use one big {{#switch}} that would contain the variables and their values (this requires the ParserFunctions extension):
{{#switch: {{{1}}}
| MAIN_WEB_URL = some value
| MAIN_TEAM_DISTRIBUTION_LIST = another value
}}
You would then call it like this:
{{variable|MAIN_WEB_URL}}
(BTW, I am not a fan of ALL_CAPS names and I think there is no reason to use them here, but that's up to you.)
I have a table that contains text fields. In those fields I store text. There are around 20 to 50 sentences in each field depending on the row. I am making an auto-complete HTML object with HTML and PHP, and I would like to start typing the beginning of a word and that the database return sentences containing those words (Like Microsoft office 2007/2010 navigation pane).
I need mysql to return those words or sentences as a separate result, so i can manipulate them further.
Example:
--------------------------------------------------------------------
| id | title |content |
--------------------------------------------------------------------
1 | test 1 | PHP is a very nice language and has nice features.
2 | test 2 | Spain is a nice country to visit and has nice language.
3 | test 3 | Perl isn\'t as nice a language as PHP.
I need mysql query to return following as different result:
1,"nice language"
1,"nice features"
2,"nice country"
2,"nice langugage"
3,"nicea a language"
Here is my sql query:
SELECT id, SUBSTR(content,POSITION('nice' IN content),50)
FROM entries
MATCH (title,entry) AGAINST ('nice' WITH QUERY EXPANSION)

OP is actually asking nothing to do with php and javascript - his question concerns doing string manipulation directly within MySQL.
String manipulation isn't really the main focus of a DBMS. When dealing with "words" in a fluid text sense, there's a lot of logic required to determine where the next word boundary is, and you don't want your database doing this really. Plus, any queries written to do this will probably be incredibly difficult to read.
It depends exactly what you are doing, but it's quite likely that a DB only approach will be slower because there will be more function calls: SQL functions are pretty limited.
And for re-usability and best practice, what if you wanted to change your database in the future to say MongoDB? You'd need to re-write the whole damned awkward query.
No, my suggestion would be to pull the whole value using standard MySQL into PHP, throw it into PCRE, very simple regex, job done. It's better to show what you're actually doing in your PHP code as it's more "intention revealing".
At least 33% of a developer's work is picking the right tool for the job. PHP is the right tool in this example.
Original Answer
You have included the tags php and javascript, so I'm guessing (although your question needs more clarification on this) that you obviously want this 'autocomplete' running client-side. So as a result, you have to get your data from server-side to client-side first.
Twitter Bootstrap has something really cool called Typeahead. This uses JavaScript to perform (what I think) you require: the example on that page shows how you can type a country and it'll auto-complete it for you. It looks like this:
How do you get this working? Include the required JavaScript file first, and then write your HTML.
Here's some from the source code of the bootstrap page so you can see how it works:
<input type="text" data-provide="typeahead" data-items="4" data-source='["Alabama","Alaska","Arizona","Arkansas","California"]'>
Can you see how the data-source attribute is the one that gives the typeahead the information you want? You want to connect to MySQL, grab your data, and shove these into the data-source array for the JavaScript to work with, as above.
So, on your page load, you connect to MySQL and you pull all the relevant strings you would like to be "auto-complete-able" from the Database. You then put these as new Data attributes for the typeahead, and that's pretty much it!
--
Edit: There's a fork of twitter bootstrap's typeahead that allows AJAX calls, so you could use this to perform the data retrieval asynchronously (if you can figure it out, I'd recommend this approach).
Is there a way I can create a database from which to pull data into my mediawiki table? Or is there a way to have a database like drupal and place a mediawiki type interface on it?
There is no way to directly do this in stock MediaWiki, although you can fake it up somewhat with templates. For example, you could can a template something like this:
{{#switch:{{{key}}}
| key1 = value1
| key2 = value2
| key3 = value3
...
}}
Template:NUMBEROF/data on the English Wikipedia is an example of this style (with two levels of keys).
Or you can create a set of templates, one for each "record", that each take an "output formatter" template as a parameter and pass that output formatter a named parameter for each column in the record. The Country data templates on the English Wikipedia are an example of this pattern.
Or you could combine the above two styles, with one parameter to select the row (as in the first style) and a second to provide the output formatter (as in the second).
If you don't mind installing extensions, you could use the Labeled Section Transclusion extension to transclude sections of a data page. Or you could install the Semantic MediaWiki extension, which I hear allows all sorts of querying of data from the wiki's pages. Or you could install one of the many Database extensions that may allow you to do what you want. Or you could write your own database extension.
You could also have a look at http://www.mediawiki.org/wiki/Extension:Data_Transfer, which do not require Semantic MediaWiki even though it's written for use with SMW. (If you use SMW there are, as noted in an earlier reply, plenty extensions and built in options.)
