[Typo3] building teaser using only TypoScript

[Krystian Szymukowicz]

hi all

i want to do some kind of teaser using only TS.

I got following structure

Page1
|____Subpage 1
|____Subpage 2
|____Subpage 3
|____Subpage 4

Every Subpage has 4 tt_content elements
1. header1
2. header2
3. image
4. table

What I want to do is to show at Page1 following content in the table:

<table>

<tr><td> header2 of subpage1 </td></tr>
<tr><td> image of subpage1   </td></tr>

<tr><td> header2 of subpage2 </td></tr>
<tr><td> image of subpage2   </td></tr>

<tr><td> header2 of subpage3 </td></tr>
<tr><td> image of subpage3   </td></tr>

<tr><td> header2 of subpage4 </td></tr>
<tr><td> image of subpage4   </td></tr>

</table>

I have spend 2 days digging into TS and finally done something like that:



lib.a = CONTENT
lib.a {
   table= pages
   select {
		 #pid of Page1
     pidInList = 3
     selectFields = uid
     orderBy = title
   }

   renderObj = CONTENT
   renderObj {
     table = tt_content
     select {
       pidInList.field = uid
       where = sys_language_uid = 0
		#get only "header2" and "image"
       begin =1
       max = 2
       orderBy = sorting
     }
     renderObj = COA
     renderObj {
		#try to remember header value to use it later
       5 = LOAD_REGISTER
       5.my_header.cObject = TEXT
       5.my_header.cObject.data =  field:header
       5.my_header.cObject.if.isTrue.field = header

       10 = COA
       10.wrap = <table width="250">|</table>
       10 {
         if {
			#dont do table if its content/render loop
			#with "header" tt_content
           isFalse.field = header
         }

         10 = TEXT
         10.value=<tr><td width="250">

         20 = TEXT
         20.wrap = <a href="|">
         20.typolink.parameter.field = pid
         20.typolink.returnLast=url

         25 = IMAGE
         25.file.import = uploads/pics/
         25.file.import.field = image
         25.file.width = 100

         30 = TEXT
         30.value=</a></td></tr>

         40 = TEXT
         40.wrap = <tr><td>|</td></tr>
		#try to use remembered header value here - DOES NOT WORK
         40.data = register:my_header

       }
     }
   }
}



Well - it almost work :) all images are displayed but I can't figure out 
how to display header together with images and I must ask you to help me 
here :)



The code I think is bad here is:

      5 = LOAD_REGISTER
      5.my_header.cObject = TEXT
      5.my_header.cObject.data =  field:header
      5.my_header.cObject.if.isTrue.field = header

Here in the first loop of content/render when I have "header" tt_content 
I am trying to remember header value (sorry if it is funny but this is 
how I imagine it works).

Then in the second loop of content/render when I have "image" tt_content 
I want to use this value from first loop but IT DOES NOT work :(

    40 = TEXT
    40.wrap = <tr><td>|</td></tr>
    40.data = register:my_header

I know that in the second loop register will be done again but I hope 
that line

5.my_header.cObject.if.isTrue.field = header

can be understand as following condition "if header is empty do not do 
anything with register:my_header" so I hope the previous value of 
register:my_header is remembered. Maybe I am wrong here.


I am quite sure it can not be the right way of doing teaser with 
TypoScript as it would be complicated if I would like to use more 
tt_content.

Could you be so kind to share your knowledge and show me the right 
direction of doing such teaser?

I know there are some extention but I would like to do it with TS only 
as it is more flexible solution.

thank you very much
