looping in a loop?

Hi petejdg,

Here's some code that I used to list types of exhibitions and the year that they occurred in for a resume list page.

The 'category' field is a pull down list field that get it's values from a multi-record database (advanced option) called 'resume_categories' with one field called 'category'. Take the field option values from the record number (num) and the field option labels from the 'category' field.

:label is pseudo field code to display the text in the category field and not the record number.

You can see the result here

Hope it gives you some ideas.

Best,

Jerry Kornbluth

<table align="left" border="0" cellpadding="0">
<?php $old_group = ''; // init blank var.
$old_year = ''; // init blank var.
foreach ($resumeRecords as $record): ?>
<?php $category = $record['category:label']; ?>
<?php $group = strtoupper($record['category']); // load sub-group value from record. ?>
<?php $year = $record['year']; // load year value from record. ?>
<tr>
<td align="left" >
<?PHP if ($group != $old_group) {echo "<div class='subheading' ><br />$category</div><br />";}?>

<?php

if (!preg_match("/^http:\/\//i", $record['url'])) {
$record['url'] = "http://" . $record['url']; }

?>

<table width="100%" cellpadding="1" border="0">
<tr>
<td class="text" width="9%" align="left" valign="top"><?php if ($year != $old_year) {echo "$year";}?></td>
<td class="text" width="2% "align="right"valign="top">&bull;&nbsp;</td>
<td class=" text" align="left" valign="top"> <?php $entry = $record['entry']; ?> <?php echo $entry; ?><br />
<a class="special" href="<?php echo $record['url'] ?>" target="_blank"><span class="text"><u><?php echo $record['link_text'] ?></u></span></a>
</td>
</tr>
</table>

</td>
</tr>
<?PHP $old_group = $group; // retain sub-group name before moving to new record. ?>
<?PHP $old_year = $year; // retain sub-group name before moving to new record. ?>
<?php endforeach; ?>
</table> </td></tr>
</table>

Thanks for the help. I really don't exactly know what I am doing but played around with it tonight and thought I had it working but for some reason it looks like it is limiting two longer months to just 10 items?????

My code now:

<?php header('Content-type: text/html; charset=utf-8'); ?>
<?php


// load viewer library
$libraryPath = 'cmsAdmin/lib/viewer_functions.php';
$dirsToCheck = array('C:/inetpub/wwwroot/','','../','../../','../../../');
foreach ($dirsToCheck as $dir) { if (@include_once("$dir$libraryPath")) { break; }}
if (!function_exists('getRecords')) { die("Couldn't load viewer library, check filepath in sourcecode."); }

// load records
list($trade_showsRecords, $trade_showsMetaData) = getRecords(array(
'tableName' => 'trade_shows',
'orderBy' => 'year',
));

?>
------------------------------------------
<?php $old_group = ''; // init blank var.
$old_month = ''; // init blank var.
foreach ($trade_showsRecords as $record): ?>
<?php $group = $record['year']; // load sub-group value from record. ?>
<?php $month = $record['month']; // load year value from record. ?>

<?php if ($group != $old_group) {echo "<div class='subheading'><br />$group</div><br />";}?>


<?php if ($month != $old_month) {echo "<div class='subheading2'><br />$month</div>";}?>
<table width="720" cellpadding="0" border="0">
<tr>
<td width="270" align="left" valign="top"><?php if ($record['link']): ?><a href="<?php echo $record['link'] ?>"target="_blank"> <?php echo $record['title'] ?></a><?php else: ?><?php echo $record['title'] ?><?php endif ?> </td>
<td width="230" align="left" valign="top"><?php echo $record['location'] ?></td>
<td width="180" align="left" valign="top"><?php echo $record['date'] ?></td>
</tr>
</table>

<?PHP $old_group = $group; // retain sub-group name before moving to new record. ?>
<?PHP $old_month = $month; // retain sub-group name before moving to new record. ?>
<?php endforeach; ?>

Hi,

I took a look at your output and January and February are repeated twice.

Here is another approach where we first organize all of our records into a multi-dimensional array, organized by year and then month, before we output them. We the output our data using 3 nested loops. Nested loops can be expensive, but the code is a little cleaner and may work a little better for you.

Give this a try:

<?php header('Content-type: text/html; charset=utf-8'); ?>
<?php


// load viewer library
$libraryPath = 'cmsAdmin/lib/viewer_functions.php';
$dirsToCheck = array('C:/inetpub/wwwroot/','','../','../../','../../../');
foreach ($dirsToCheck as $dir) { if (@include_once("$dir$libraryPath")) { break; }}
if (!function_exists('getRecords')) { die("Couldn't load viewer library, check filepath in sourcecode."); }

// load records
list($trade_showsRecords, $trade_showsMetaData) = getRecords(array(
'tableName' => 'trade_shows',
'orderBy' => 'year',
'allowSearch' => false,
));

$yearMonthToRecords = array();

foreach ($trade_showsRecords as $record) {
$year = trim($record['year']);
$month = trim($record['month']);

// initialize array
if (!array_key_exists($year, $yearMonthToRecords)) {
$yearMonthToRecords[$year] = array();
}

if (!array_key_exists($month, $yearMonthToRecords[$year])) {
$yearMonthToRecords[$year][$month] = array();
}

$yearMonthToRecords[$year][$month][] = $record;

}

?>
------------------------------------------

<?php foreach ($yearMonthToRecords as $year => $monthsToRecords): ?>
<div class='subheading'><br /><?php echo $year; ?></div><br />

<?php foreach ($monthsToRecords as $month => $records): ?>
<div class='subheading2'><br /><?php echo $month; ?></div>
<table width="720" cellpadding="0" border="0">

<?php foreach ($records as $record): ?>
<tr>
<td width="270" align="left" valign="top"><?php if ($record['link']): ?><a href="<?php echo $record['link'] ?>"target="_blank"> <?php echo $record['title'] ?></a><?php else: ?><?php echo $record['title'] ?><?php endif ?> </td>
<td width="230" align="left" valign="top"><?php echo $record['location'] ?></td>
<td width="180" align="left" valign="top"><?php echo $record['date'] ?></td>
</tr>
<?php endforeach ?>

</table>
<?php endforeach ?>

<?php endforeach; ?>

Hope this helps

Wow. Brilliant! Works awesome... thank you!

Jason, this is working good, but how can I have the records sorted by the drag sort order? Since some of the tradeshows span multiple days, etc. I need to be able to choose the order they appear for the day. I don't see how it is ordering them currently but would like to do the drag sort order.

Hi,

Currently, your records are being sorted by year, this is to ensure that the years are output in a reasonable order (ie, 2011 before 2012). If you want to revert to dragSortOrder you can try removing the orderBy option altogether:

// load records
list($trade_showsRecords, $trade_showsMetaData) = getRecords(array(
'tableName' => 'trade_shows',
'orderBy' => 'year',
'allowSearch' => false,
));

How well this will work will depend on the order of all your records since the code is re-arranging the records by year/month.

Hope this helps

Is there a way leave it sorty by year and month but then allow for a drag sort order for just the tradeshow records? Or is my only option to just delete the sort by year like you stated?
