iw_itereate counter

Satan

I'd like to code an iw_if statement that keeps track of how many iterations of a replicant there are. For example, if this is the first time through the iteration loop, then start a new TR, if it's the second, start a new TD, if it's the third, start a new TD and close the TR, etc.

any thoughts?

thanks

before the iw_iterate put an iw_perl that initializes a counter variable. Inside the iw_iterate use an iw_perl to increment the variable.

Maybe there is a cleaner way.

That sounds pretty clean, actually. Can you point me to a resource for the needed Perl code?

thanks!

If you are not using loose presentation templates you should. Otherwise you should put the opening and closing CDATA things. I don't have time for the Perl and I;m sure someone else could do a better job of this but it might look something like:

<iw_perl><![CDATA[

my ${counter} = 0;

]]></iw_perl>

<iw_iterate [whatever]>
<iw_perl><![CDATA[

my ${html} = "";

if ( some condition on ${counter} )
{
${html} = whatever;
}
elsif ( some other condition on ${counter} )
{
${html} = whatever;
}

iwpt_output( ${html} );

]]</iw_perl>
</iw_iterate>

Hi all, my query is related to the counter problem. I have the following HTML block that I need to iterate::

menu_content = new Array('<a href="http://www.google.com"class=subMenu>google tool bar </a> |<a href="http://www.google.com/search?hl=en&lr=&ie=UTF-8&oe=UTF-8&q=&btnG=Google+Search"class=subMenu>google search </a> |',
'<a href="http://www.abc.com"class=subMenu>ABC Menu Name </a> |<a href="https://www.utlimatix.net"class=subMenu>ABC New Menu </a> |',
'<a href="http://www.indiatimes.com"class=subMenu>indiatimes Cricket </a> |<a href="http://www.email.indiatimes.com"class=subMenu>Indiatimes Email </a> |');

For generating this repititive HTML, i am using the following Presentation template code ::

menu_content = new Array(
]]>
<iw_iterate var='menu_name' list='dcr.MenuHeading'>
<![CDATA[']]>
<iw_perl>
<![CDATA[$m=0;]]>
</iw_perl>
<iw_iterate var='menu_link' list='menu_name.MenuItem'>
<iw_perl>$m++;</iw_perl>
<![CDATA[ <a href="<iw_value name='menu_link.MenuItemURL'/>"]]><![CDATA[class=subMenu>]]><iw_value name='menu_link.MenuItemName'/><![CDATA[ </a> |]]>
</iw_iterate><![CDATA[',]]>
</iw_iterate><![CDATA[);
Now the probs is that using this code, the HTML gets generated, but the ,(comma) in the line (</iw_iterate><![CDATA[',]]>) creates problem due to which I can get the correct output. I do not need that comma in the last iteration. For this I need to know by how much my counter wud iterate before hand, so that I can put the other format in some if condition. Can anybody give some idea on this?
Thanks

Two options I could think of are:

1. You could have one more iterate block inserted before this iterate. I mean, the dummy one will parse through all replicant values and create a counter variable for you.

2.
<iw_perl>
<![CDATA[
my @list = iwpt_dcr_list('dcr.a.b');
my $ctr = scalar(@list);
iwpt_output($ctr);
]]>
</iw_perl>

Ofcourse, replace a and b with your replicant item names. And at the end ctr variable can be used in the main iterate block tha tyou have with iw_if tag.

Hope this helps!

Here's an idea simlar to akshat's:

1) first, use <iw_perl> to get/set the number/list of elements to iterate over. E.g.,

<iw_perl><![CDATA[
my @names = iwpt_dcr_list('dcr.names');
my @list = (0 .. $#names );
]]>
</iw_perl>

2) then iterate over the list, accessing the container/replicant items by index:

<iw_iterate var="index" list='(@list)'>
<iw_value name='dcr.names[$index].firstName'/>
....

just to say that first there is the "iteration" option in the iw_iterate that retain the number of the current iteration

<iw_iterate var="variable" list="dcr.brol" iteration="current_iteration_number">
<iw_value name="current_iteration_number"/>
</iw_iterate>

And for your problem that you you don't want the , in the last iteration you can reverse the display...let me explain...
<iw_iterate var="variable" list="dcr.brol" iteration="current_iteration_number">

<iw_if expr='{$current_iteration_number != 0 }'>
<iw_then>
iwpt_output(',');
</iw_then>
</iw_if>
display what you want here
</iw_iterate>
