Question

我在where子句中得到错误未知数组。我知道$项目是一个数组，但我怎么能在where子句中修复这个问题？（我正在使用codeigniter）。

<?php

function rapport_detail_opbrengsten($idKlant) {
    $this->db->from('Project');
    $this->db->join('Opbrengsten', 'Opbrengsten.idProject = Project.idProject');
    if ($idKlant > 0) {
        $this->db->where('idKlant', $idKlant);
    }
    $query = $this->db->get();
    $project = array();
    foreach ($query->result() as $row) {
        $project[] = $row->idProject;
    }
    $test[] = $project;

    $this->db->select('idProject, SUM(Prijs) as total');
    $this->db->from('Opbrengsten');
    $this->db->where_in('idProject', $test);
    $this->db->group_by('idProject');
    $query = $this->db->get();

    if ($query->num_rows() > 0) {
        return $query->result();
    } else {
        return false;
    }
}

?>
