Hi, I cannot for the life of me figure this out, maybe someone can help.
Using MODX a form takes user criteria to create a filter and return a list of documents. The form is one text field and a few checkboxes. If both text field and checkbox data is posted, the function works fine; if just the checkbox data is posted the function works fine; but if just the text field data is posted, modx gives me the following error:
Error: implode() [function.implode]: Invalid arguments passed.
I've tested this outside of modx with flat files and it all works fine leading me to assume a bug exists within modx. But I'm not convinced. Here's my code:
<?php
$order = array('price ASC'); //default sort order
if(!empty($_POST['tour_finder_duration'])){ //duration submitted
$days = htmlentities($_POST['tour_finder_duration']); //clean up post
array_unshift($order,"duration DESC"); //add duration sort before default
$filter[] = 'duration,'.$days.',4'; //add duration to filter[] (field,criterion,mode)
$criteria[] = 'Number of days: <strong>'.$days.'</strong>'; //displayed
on results page
}
if(!empty($_POST['tour_finder_dests'])){ //destination/s submitted
$dests = $_POST['tour_finder_dests'];
foreach($dests as $value){ //iterate through dests array
$filter[] = 'searchDests,'.htmlentities($value).',7'; //add dests to filter[]
$params['docid'] = $value;
$params['field'] = 'pagetitle';
$pagetitle = $modx->runSnippet('GetField',$params);
$dests_array[] = '<a href="[~'.$value.'~]" title="Read more about '.$pagetitle.'" class="tourdestlink">'.$pagetitle.'</a>';
}
$dests_array = implode(', ',$dests_array);
$criteria[] = 'Destinations: '.$dests_array; //displayed
on results page
}
if(is_array($filter)){
$filter = implode('|',$filter);//pipe-separated string
}
if(is_array($order)){
$order = implode(',',$order);//comma-separated string
}
if(is_array($criteria)){
$criteria = implode('<br />',$criteria);
}
echo '<br />Order: '.$order.'<br /> Filter: '.$filter.'<br /> Criteria: '.$criteria;
//next: extract docs using $filter and $order, display user's criteria using $criteria...
?>
The echo statement is displayed above the MODX error message and the $filter array is correctly imploded.
Any help will save my computer from flying out the window.
Thanks
