Question

我正在使用php函数创建带分页的条目的用户列表。我需要删除没有名称的条目，所以我尝试了这段代码，但它不起作用：没有删除没有名字的条目。

$listing->entries( $order, $eLimit, $eLimStart, true, array('owner' => $userid, 'name' != null), false, $section);

相反的效果很好，使用此代码我得到的所有条目都没有名称：

$listing->entries( $order, $eLimit, $eLimStart, true, array('owner' => $userid, 'name' => null), false, $section);

名称在DB中存储如下：

- type: varchar(250)
- interclassement: utf8_general_ci
- Null: Yes
- Default: NULL

我正在使用PHP版本5.3.16。

我做错了什么？非常感谢。

** 编辑 * * 上下文：Joomla 2.5.9和SobiPro 1.08。我使用SobiPro API创建列表：

$listing = SPFactory::Controller('listing');
$listing = new SPListingCtrl();

功能条目如下所示

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 );
}

函数getEntries看起来像这样：

/**
 * @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 ) {

Answer 1

不是寻找非空条目，也许你可以做相反的事情并寻找具有某些东西的条目，如下：

$listing->entries( $order, $eLimit, $eLimStart, true, array('owner' => $userid, 'name' => '%'), false, $section);

然而，这纯粹是一种猜测，因为我们需要查看entries函数来查看各种参数的处理方式。

已解决 - 感谢大家的帮助！

$ listing-＆gt;条目（$ order，$ eLimit，$ eLimStart，true，array（'owner'=＆gt; $ userid，'！name'=＆gt; null），false，-1）;

从数组中删除空值
