Anyone have any suggestions on how to sort records to show those records with uploads first, followed by other records without uploads? I can't use "drag sort" within the CMS.

Is it possible to sort upon // Load records from menu ? Similar to what's shown below?

  // load records from 'menu'
  list($menuRecords, $menuMetaData) = getRecords(array(
    'tableName'   => 'menu',
    'sort'        => 'uploads',
    'loadUploads' => true,
    'allowSearch' => false,
  ));

<?php header('Content-type: text/html; charset=utf-8'); ?>
<?php
  // load viewer library
  $libraryPath = 'cmsb/lib/viewer_functions.php';
  $dirsToCheck = array('/home/directory/html/','','../','../../','../../../');
  foreach ($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 from 'menu'
  list($menuRecords, $menuMetaData) = getRecords(array(
    'tableName'   => 'menu',
    'loadUploads' => true,
    'allowSearch' => false,
  ));

?>

Thanks Zicky

Hi, Zicky.

There may be a more elegant method, but this is what I would do.

// load records WITH a photo
list($menuRecordsPHOTO, $menuMetaData) = getRecords(array(
'tableName' => 'menu',
'loadUploads' => true,
'allowSearch' => false,
));
// load records WITHOUT a photo
list($menuRecordsNOPHOTO, $menuMetaData) = getRecords(array(
'tableName' => 'menu',
'loadUploads' => true,
'allowSearch' => false,
));

<?php foreach ($menuRecordsPHOTO as $record): ?>
<?php if ($record['photo']): ?>
<h1><a href="<?php echo $record['_link'] ?>"><?php echo htmlencode($record['name']) ?></a></h1>
<?php echo $record['content']; ?><br/>
Price: $<?php echo htmlencode($record['price']) ?><br/>
<?php foreach ($record['photo'] as $index => $upload): ?>
<a href="<?php echo $record['_link'] ?>">
<img src="<?php echo htmlencode($upload['thumbUrlPath3']) ?>" alt="<?php echo htmlencode($upload['info1']) ?>" /></a>
<?php endforeach ?>
<hr>
<?php endif; ?>
<?php endforeach ?>

<?php foreach ($menuRecordsNOPHOTO as $record): ?>
<?php if (!$record['photo']): ?>
<h1><a href="<?php echo $record['_link'] ?>"><?php echo htmlencode($record['name']) ?></a></h1>
<?php echo $record['content']; ?><br/>
Price: $<?php echo htmlencode($record['price']) ?><br/>
<hr>
<?php endif; ?>
<?php endforeach ?>

Hope that helps. :)

Hi Zicky,

An easy solution will be using usort() to specify how you want the array to be sorted. You can check the manual here for more information: http://php.net/manual/en/function.usort.php

But basically the code might be something like this:

// sort array
usort($menuRecords, 'sortByUploads');

// sort function
function sortByUploads($prev, $next){
  if(!empty($prev['photo']) && empty($next['photo'])){
    // $prev has higher priority then $next
    return -1;
  }
  else if(empty($prev['photo']) && !empty($next['photo'])){
    // $next has higher priority then $prev
    return 1;
  }
  else{
    // $prev and $next have the same priority
    return 0;
  }
}

Hope this helps and let me know if you have any questions!
