in the template.phtml file there is a line of code which refers to the content, using
getChildHtml('content') ?>
which echos out the content and the containing divs, i wish to access this raw code so i can insert
some custom data but for the life of me cannot find where it is?! i have found the Mage_Page_Block_Html class in the core but cannot see any html that it is throwing out!
Thanks in advance
In the Admin, if you go to System>Config>Advanced>Developer and select your Store View from the Scope Selector (top-left), you can turn on Template and Block hints. That will tell you exactly which PHP Block is generating the code and therefore $this relates to.
Generally, all the basic layout templates are backed by Mage_Core_Block_Template, and all blocks inherit from Mage_Core_Block_Abstract.
Cheers,

As always, I recommend understanding what the entire layout system is doing to understand what's going on.
As to your specific question, $this always refers to the template's Block class. (Every phtml template has a Block class in Magento). Which class this is will depend on what's in your layout XML files. You can always output the class at runtime with something like this
var_dump(get_class($this));
The getChildHtml method is defined on the base abstract block class
app/code/core/Mage/Core/Block/Abstract.php
This method is used by ALL blocks, so be sure you take this into account with your code.
as a side note.. if you ever wondering where a $this is point to you can also use
echo get_class($this)
helped me out quiet a few times

In the root template page.10 is already taken. If I put page.10 into my extension template, I override it. How can I make sure (just putting a large number is not "making sure") that I don't override anything? The root template is very complicated and includes many other templates, so I cannot really tell which numbers are already taken. I just want to use the extension template to append some content.
The safest solution would be not adding anything automatically. Instead you could provide your rendering instruction via lib.* or tt_content.list.* in case it is a registered plugin:
lib.yourContent = USER_INT
lib.yourContent { ... }
Then you only need to document how to add something to the page output, e.g.:
page.11 < lib.yourContent
I know it has been a while since you've asked this question.
You're saying "just putting a large number is not making sure" because you have no idea what content is using which number on the page object.
If you want to be 99,9% sure that a number has not been used, why don't you use the current timestamp as a number on this cObject? That's how the TYPO3 Errorhandler also refers to pages, using the timestamp they wrote it.
The simpliest answer if you can make sure which Page object index is already used for something is you cannot.
It might be set somewhere deeper in extensions, in any condition that meets any expression is defined there.
None of standard built in tools in TYPO3 can predict that and check all combinations of conditions to tell you if such number is set somewhere in some case.
But.
If you are an admin of that page, then the best approach is just to know your template.
Analyse the typoscript and know what numbers in Page object are used for something. Make a tidy consistent template, clean it up, check using Template tools -> Typoscript object browser. You have to know what's going on on your site, the elements in indexes of main Page object are the main and basis things which are shown public.
(Or just guess any random big number and try to search it in whole typoscript using Template tools -> Template Analyzer -> View complete TS listing. Let's be honest, probability that you shoot a big number which is already used is rather low)
I’m new to Crystal (and never really used ruby) so apologies for the ignorance here! I've looked at the ecr docs but can't seem to find an answer there.
I’m looking at using Embedded Crystal for dynamic templates in Kemal. Can I confirm - can templates only render variables that are available in the scope of the call, or can one make method/function calls from within the template itself? I.E. is there any possibility/risk of being able to execute “malicious” crystal code from within a template (in this case malicious refers to I/O or file access etc)?
To take an example from the Kemal docs:
get "/:name" do |env|
name = env.params.url["name"]
render "src/views/hello.ecr"
end
In the view hello.ecr - is name the only item that will be available in the template, or could one call File.delete("./foo")from within the template for example?
A template is compiled into Crystal code, you can write any kind of code in there, like File.delete("./foo"), for example if you write <% File.delete("./foo") %> inside of your template.
If your worry is that name will contain code and that will somehow get executed, then don't worry, that's not going to happen. Dynamic runtime code execution in Crystal is not possible, so there's no way someone will inject malicious code into your templates.
I'm trying to make my own full adder and some other devices as a sub-circuit in "Proteus" and use them several times in a bigger circuit.
The problem is when you copy a sub-circuit you need to rename all of its inner parts, otherwise, the parts with a same name in two sub-circuits would be considered as one, therefore you'd get some errors.
So I'd like to know if there is a way to define a full adder of my own and use it like "74LS183" which is a primitive device, and by primitive I mean it has been defined in the library.
From answer posted here
It's in the Proteus Help file:
SCHEMATIC CAPTURE HELP (F1) -> MULTI-SHEET DESIGNS -> Hierarchical Designs
See the section "Module Components":
Any ordinary component can be made into a module by setting the Attach Hierarchy Module checkbox on the Edit Component dialogue form.
The component's value is taken to be the name for the associated circuit,
and the component's reference serves as the instance name.
after this you can use your new implementation of that component with your new name. for making it available at library see "External Modules" section of proteus help.
The problem with copying is solved in "Proteus 8".not completely but sort of.
I mean you can copy a subcircuit without a need to change it's inner parts, but you must change the subcircuit name and I mean the bigger name above the subcircuit not the little one below it.
so there is no need to define a primitive.
I'm using Sitecore. I want to get the full name/description of a DMS rule in programcode by Sitecore ID, for example: "Where the DayOfWeek has a value that is equal to Tuesday".
Who knows how to do this?
Thanks a lot.
Jordy
I don't know of a simple way, but the class responsible for rendering the rule text is Sitecore.Shell.Applications.Rules.RulesRenderer in Sitecore.Client.dll.
Its constructor accepts the XML from a rules field and you call the Render method, passing in a prepared HtmlTexteWriter. It also has a bunch of fairly self-explanatory private methods like RenderRule, RenderCondition etc.
I'm sure if you decompile that class you can pick out the bits you need.
I am currently in the process of writing a custom DataProvider. Using the Intergrate External Data documentation.
I've managed to show the external data in the Sitecore back end. However whenever I try to view the data in the items I created, I am getting an error
Null ids are not allowed. <br> Parameter name: displayName
There seems to be precious little on the subject on how to create a custom DataProvider on the Sitecore Developer Network.
The example on their website seems to only show how to import a SINGLE item into a static database. However I am simply trying to merge some items into the hierarchy and I can't find any useful documentation.
It seems that one of your methods that should return an ID doesn't. It might be GetChildIds and/or GetParentId.
Nick Wesselman wrote a good article about it gathering all the information including an example on the Marketplace. I think that is your best start. You can read it here.
Turns out I needed to include at the very least, the Fields->Section->Template in the GetParent method. To be on the safe side I included the Fields/Sections/Templates into my implementations of
GetChildIDs
GetItemDefinition
GetParentID
It wasn't obvious that this was the case, since I had in fact implemented the GetTemplates method correctly, and I had expected that should be enough.
