category listings / finding last record

btw,

the category section editor want recommended before for a list of categories and items like a food menu, is this still true in 1.27?

I hope I have been clear and can get some help today. I just need to control where that one little </events> tag goes to finish. I don't know that u r available on the weekends.

Thanks

hmmm... wont that put it after every event? i only need it after all the events for each date, once at the end before the next date...

so it would be a "not equal too" but it probably wont add it for the final date...



I'll experiment again but do you know what I mean? There may be 3 events: <event>event info </event> but notice above in my pseudo code that the </eventS> only goes once after them, before the next date.



I've confused myself but wanted to get that in before you are gone for the day. And I'm on my way to opening day, O's and yankees and will experiment when I get back. :) ... if I can... ;)

Hi Rez

My code will be checking if the current date equals the previous date. If it does, it's still the same day and you don't need a closing </events> tag. If it is a different date, you need that closing tag.

I do agree that it will likely not create the last </events> tag but you can just move that outside of the foreach loop.

It's pretty much working the same way as the code you have for checking the groups.

still can't figure it out :(

i need, "if the current date is a new date, put a </events> at the end of the last <event> in that date only."

1 of my tries results:
<events date="21-10-2010" color="0x99CC00"><event>
<event>
<title> Event 4</title>
<group>another group</group>
<where>somewhere</where>
<when>12pm sharp</when>

<description><![CDATA[Curabitur tempus rutrum purus. Praesent massa quam, tincidunt eu, sollicitudin quis, rutrum nec, tortor. Nulla facilisi. Phasellus euismod metus et lacus. Fusce nisi. Curabitur eu orci vitae augue pulvinar eleifend. Etiam eleifend dictum mauris.]]></description>
</event>

</events> // this is fine, it's after all events (it only worked because there is one event

<events date="11-04-2011" color="0x99CC00"><event>
<event>
<title>Same Day Test Event</title>
<group>test</group>
<where>patio</where>
<when>whenever</when>
<image></image>
<description><![CDATA[test description of an event]]></description>
</event>

</events> //this is not fine, its between two events on the same date


<event>
<title>Another Same Day Test</title>
<group>Test Group</group>
<where>a place</where>
<when>sometime on this day</when>
<image></image>
<description><![CDATA[Test Description again]]></description>
</event>


//this is where the above <events/> should go instead, because it is after the two events for this date.

</xml>




<<?php ?>?xml version="1.0" encoding="utf-8"?>
<xml>
<?php
// list a category name , then all its entries using a variable named group
$old_group = ''; // init blank var.
$prevDate = '';
foreach ($eventsRecords as $record):
$group = $record['date']; // load sub-group value from record.
$curDate = $record['date'];?>
<?php if ($group != $old_group):?>
<events date="<?php echo date("d-m-Y", strtotime($record['date'])) ?>" color="0x99CC00"><event>
<?php endif ?>
<event>
<title><?php echo $record['title'] ?></title>
<group><?php echo $record['group'] ?></group>
<where><?php echo $record['where'] ?></where>
<when><?php echo $record['when'] ?></when>
<image><?php foreach ($record['image'] as $upload): ?><?php if ($upload['isImage']): ?><?php echo $upload['urlPath'] ?><?php endif ?><?php endforeach; ?></image>
<description><![CDATA[<?php echo $record['content'] ?>]]></description>
</event>

<?php $old_group = $group; // retain sub-group name before moving to new record. ?>
<?php if ($prevDate != $curDate):?>
</events>
<?php endif ?>
<?php $prevDate = $curDate; ?>
<?php endforeach ?>

</xml>

Sorry that I'm not getting it Ross. I keep getting the </events> tag after every event, or only once after all the dates, at the bottom. With everything I've tried, it's confusing to me why I would even need to use another variable like $prevDate because i'm already using the date in the group, so i guess I'm just bnot placing things or resetting the variable in the right place.



I can't figure out how to find where the last </event> is with multiple <event> entries on 1 date. If i put the if statement outside of my current conditionals, it only ends up at the bottom of the entire xml, after all dates. :( But it's true, even if there are 30 </event> tags (30 events on one date) the </events> tag only goes after the last </event> on that date. I dont think there is a way to detect the last </event> on a date but there is way to detect a new date of course. The </events> tag goes before a new date, which will place it correctly. (but not before the first date at the top)

But on the last date listed, as you say, there will not be a new date to put it before. I guess I can handle that with a "last item on the list check" or something, but i haven't even got that far. :(

Hi rez

It's definitely possible so we can keep at it if you like. I think we are just missing each other on the setup.

I am curious if there might be another way to do it though. Instead of using the PHP to get those dates figured out, why don't you just let this page display as it is now (with the </events> after each event. Then, maybe there is something you can tweak in the application that receives this xml file so that it handles the dates the way you need.

I don't actually know what you are using this feed with though so I don't know if that will be easier. Let me know what you think. We'll keep at it here if you like :).

Hi Ross. That's a good idea but unfortunately, I dont have the source for this application. Seems so simple in my head to make the tag end up before each new date but since I'm a new to this, it's not happening. Anyway, I'm going to give it another try today if you have an idea or clarification I'm looking forward to your input. Thanks for your help so far.
