Remove empty values from an array - php

Question

I'm using a php function to create a user listing of entries with pagination. I need to remove entries without name so I tried this code but it doesn't work: entries without name are not removed.
$listing->entries( $order, $eLimit, $eLimStart, true, array('owner' => $userid, 'name' != null), false, $section);
The opposite works well, with this code I get all entries without name:
$listing->entries( $order, $eLimit, $eLimStart, true, array('owner' => $userid, 'name' => null), false, $section);
The name is stored like this in the DB:
- type: varchar(250)
- interclassement: utf8_general_ci
- Null: Yes
- Default: NULL
I'm using PHP Version 5.3.16.
What am I doing wrong please? Thanks a lot.
** EDIT **
The context: Joomla 2.5.9 and SobiPro 1.08. I use SobiPro API to create the listing:
$listing = SPFactory::Controller('listing');
$listing = new SPListingCtrl();
The function entries looks like this
public function entries( $eOrder, $eLimit = null, $eLimStart = null, $count = false, $conditions = array(), $entriesRecursive = false, $pid = -1 )
{
return $this->getEntries( $eOrder, $eLimit, $eLimStart, $count, $conditions, $entriesRecursive, $pid );
}
The function getEntries looks like this:
/**
* #param string $eOrder
* #param int $eLimit
* #param int $eLimStart
* #return array
*/
public function getEntries( $eOrder, $eLimit = null, $eLimStart = null, $count = false, $conditions = array(), $entriesRecursive = false, $pid = 0 )
{
/* var SPDb $db */
$db =& SPFactory::db();
$eClass = SPLoader::loadModel( 'entry' );
$entries = array();
$eDir = 'asc';
$oPrefix = null;
$conditions = is_array( $conditions ) ? $conditions : array();
/* get the ordering and the direction */
if ( strstr( $eOrder, '.' ) ) {
$eOr = explode( '.', $eOrder );
$eOrder = array_shift( $eOr );
$eDir = implode( '.', $eOr );
}
$pid = $pid ? $pid : SPRequest::sid();
/* if sort by name, then sort by the name field */
if ( $eOrder == 'name' ) {
$eOrder = SPFactory::config()->nameField()->get( 'fid' );
}
if ( $entriesRecursive ) {
$pids = $this->_model->getChilds( 'category', true );
if ( is_array( $pids ) ) {
$pids = array_keys( $pids );
}
$pids[ ] = SPRequest::sid();
$conditions[ 'sprl.pid' ] = $pids;
}
else {
$conditions[ 'sprl.pid' ] = $pid;
}
if ( $pid == -1 ) {
unset( $conditions[ 'sprl.pid' ] );
}
/* sort by field */
if ( strstr( $eOrder, 'field_' ) ) {
static $field = null;
$specificMethod = false;
if ( !$field ) {
try {
$db->select( 'fieldType', 'spdb_field', array( 'nid' => $eOrder, 'section' => Sobi::Section() ) );

Answer 1

Instead of looking for non empty entries, perhaps you could do the opposite and look for entries that have something, like so:
$listing->entries( $order, $eLimit, $eLimStart, true, array('owner' => $userid, 'name' => '%'), false, $section);
This is purely a guess, however, as we would need to see the entries function to see how the various parameters are being handled.

Answer 2

SOLVED - Thanks everyone for your help !
$listing->entries( $order, $eLimit, $eLimStart, true, array('owner' => $userid, '!name' => null ), false, -1);
