iw_iterate

Hi,

Does iw_iterate support a counter?

It would be really usefull if I could include a counter that increments each time the iw_iterate loops.

I've seen some code which includes a iteration attribute: (see below)

When I use {iw_value name='counter'/} it always returns zero for each loop.

Can anyone help? Am I using the right code??

Thanks

Steve

Sorry, code attached below.

<iw_iterate var="xc" list="x.ManyPics" iteration="counter">

RTFM - http://your-server/iw/help/tst/pt/TeamSite__PT__iw_iterate.html

in there you'll see an example using the iteration parameter - and you'll see the syntax used for referencing it within an iw_if expression.

HI,

Thanks for the link, I'm new to Teamsite and did not know of the help files.

I've followed the help page but I am still getting 0's for all iterations. Here is a snipet of code

<iw_iterate var='xc' list='x.ManyPics' iteration='counter'>
<![CDATA[
<script language="javascript">var strCaption{iw_value name="$counter"/}="{iw_value name='xc.Caption'/}";</script>
]]>
</iw_iterate>

I add the $ to the counter in iw_value as per the help page, but its not incrementing still.

Can you help?

Someone else will have to pitch in here - I tend to do most of my PT coding in Perl rather than pseudo-XML - and I don't have time right now to play with this. Sorry.

If you just want the value output into your resulting html/javascript then you could just use something like <iw_value name='current_color'/>. Use <...> instead of {....}.

The second type appear to be the syntax you use only when you are evaluating the values, such as in iw_if tags.

Hope this helps

Cheers

Hi,

Tried changing the ()'s to <>'s but still no joy Smiley Sad

Is there another way I can do this?

What does does 'x' represent in: list='x.ManyPics'

If it's the xml file (dcr) then replace x with dcr: list='dcr.ManyPics'

]]>
<iw_iterate var='xc' list='dcr.ManyPics' iteration='counter'>
<iw_value name="$counter"/>
</iw_iterate>

'x' is a var to the parent iw_iterate. <iw_iterate var="x" list="dcr.text">

The TPL works, it generates the page correctly. The page consists of text and images (thumbnails) and what I would like to do is show the full image in a pop-up window when the image or piece of text is clicked on. I decided to do this with javascript and give each image a unquie ID and name with this line going inside the iw_iterate loop.

<img name="rpic<iw_value name="$counter"/>" src="{iw_value name='xc.Picture'/}" border="0" align="" alt="<iw_value name='xc.Caption'/>" />

LooseCannon

is 'dcr.text.ManyPics' a replicant

Wackie

Yes, Manypics is a replicant

Could you pls post the attachments of DCT and TPL files, I did this kind of stuff and worked fine for me.
Thanks,
KT

Thanks,

See attached file

Pls try with the following attachment. I never changed the DCT, but, did some changes on TPL code( especially on 'counter'). Let me know as soon you test this.

LooseCannon

I think your logic/code that displays the counter value is causing you problems not the logic/code that increments the counter.

I created a dct from your attachment and a simple tpl that display's the counter value. Works fine.

You need to simplify the code and start debugging

Wackie

KTR,
Thanks for the looking at the TPL, I tried it but it did not work, still 0's for each iteration.

LooseCannon,
Could you please attach the TPL you created, si I can compare your TPL and my TPL, hopefully it will show me where the errors are my TPL.

Thanks a lot

Steve

Here is the tpl (if you view source on the attachment from my previous post you will find it as well). I created 3 ManyPics replicants.

<?xml version="1.0" encoding="UTF-8"?>
<![CDATA[
<html>
<body>
]]>
<iw_iterate var="x" list="dcr.text">
<iw_iterate var='xc' list='x.ManyPics' iteration='counter'>
<![CDATA[<p>COUNTER VALUE:<iw_value name="$counter"/></p>]]>
</iw_iterate>
</iw_iterate>
<![CDATA[
</body>
</html>
]]>

As an FYI - your PT's do not have to be well-formed XML - which allows you to get rid of all the CDATA tags and make the PT easier to read - so you can change this:<?xml version="1.0" encoding="UTF-8"?>
<iwpt name="example">
<![CDATA[
<html>
<body>
]]>
<iw_iterate var="x" list="dcr.text">
<iw_iterate var='xc' list='x.ManyPics' iteration='counter'>
<![CDATA[<p>COUNTER VALUE:<iw_value name="$counter"/></p>]]>
</iw_iterate>
</iw_iterate>
<![CDATA[
</body>
</html>
]]>
</iwpt>to this:<iwpt name="example"/>
<html>
<body>
<iw_iterate var="x" list="dcr.text">
<iw_iterate var="xc" list="x.ManyPics" iteration="counter">
<p>COUNTER VALUE: <iw_value name="$counter"/></p>
</iw_iterate>
</iw_iterate>
</body>
</html>
This style of writing PT's has been available since TS 5.0.1 and is officially supported.

Sorry for not replying to you earlier.

Thanks the FYI. Most of the PT's were created a few years ago so they are all formatted as valid XML docs.

I've copied your example and I sill get four 0's being written to the screen.

<iw_iterate var="x" list="dcr.text">
<iw_iterate var="xc" list="x.ManyPics" iteration="counter">
<![CDATA[ Counter= <iw_value name='$counter'/> <br> ]]>
</iw_iterate>
</iw_iterate>

Here is an example from some of my code. This is from a replicant.

<![CDATA[<modelDesc>]]><iw_value name='dcr.modelDesc'/><![CDATA[</modelDesc>]]>

<iw_iterate list='dcr.fileData' var='filedata'>

<iw_perl><![CDATA[
my $fileName = iwpt_dcr_value('dcr.fileData[$count].fileName');
my $fileType = iwpt_dcr_value('dcr.fileData[$count].fileType');
my $fileSize = iwpt_dcr_value('dcr.fileData[$count].fileSize');
my $downloadTime = iwpt_dcr_value('dcr.fileData[$count].downloadTime');
#my $fileDesc = iwpt_dcr_value('dcr.fileData[$count].fileDesc'); # called from below
$count=$count + 1;
]]></iw_perl>

<iw_iterate list='filedata.fileDesc' var='filedesc'>
<![CDATA[<fileDesc>]]><iw_value name='filedesc'/><![CDATA[</fileDesc>]]>
</iw_iterate>

</iw_iterate>

Wackie

Thanks,

I don't know Perl too well but your code did show me an approach I could use with ASP. Here is my code which now shows
Counter 0
Counter 1
Counter 2
Counter 3

Thanks for your help
