Question

我在控制器中有这样的功能。我需要将$data1['hasil1']的结果插入tampilInduk。

public function sikap(){
    $person=$this->session->userdata('idperson');
    $data1['hasil1']=$this->M_Guru->tampilNik($person);

    $data2['hasil2']=$this->M_Guru->tampilInduk($data1);
    $this->load->view('sidebarGuru');
    $this->load->view('navbarGuru');
    $this->load->view('kompetensiSikap',$data1+$data2);
}

我有这样的模型代码

public function tampilInduk($data1){
        $this->db->select('induk');
        $this->db->from('kelas b');
        $this->db->join('siswa_kelas c','c.namakelas= b.namakelas','c.thnakademik=b.thnakademik','c.kdtingkat=b.kdtingkat','right');
        $this->db->where('nik',$data1);
        $data = $this->db->get(); //mengambil seluruh data
        return $data->result();
    }

public function tampilNik($person){
        $this->db->select('nik');
        $this->db->from('guru');
        $this->db->where('idperson',$person);
        $data=$this->db->get();
        return $data->row()->nik;
    }

但是错误提示该变量需要首先转换为字符串。您能帮助我如何将数组转换为字符串吗？

Answer 1

这应该有效：

public function sikap(){
    $person=$this->session->userdata('idperson');
    $data1['hasil1']=$this->M_Guru->tampilNik($person);

    $data2['hasil2']=$this->M_Guru->tampilInduk($data1['hasil1']);
    $this->load->view('sidebarGuru');
    $this->load->view('navbarGuru');
    $this->load->view('kompetensiSikap',$data1+$data2);
}


   public function tampilInduk($nik){
        $this->db->select('induk');
        $this->db->from('kelas b');
        $this->db->join('siswa_kelas c','c.namakelas= b.namakelas','c.thnakademik=b.thnakademik','c.kdtingkat=b.kdtingkat','right');
        $this->db->where('nik',$nik);
        $data = $this->db->get(); //mengambil seluruh data
        return $data->result();
    }

public function tampilNik($person){
        $this->db->select('nik');
        $this->db->from('guru');
        $this->db->where('idperson',$person);
        $data=$this->db->get();
        return $data->row()->nik;
    }

Answer 2

您可以使用$this->db->where('nik',$data1['hasil1']);代替$this->db->where('nik',$data1);

Answer 3

您可以尝试解决此问题的方法：

public function tampilInduk($data1) {
        $this->db->select('induk');
        $this->db->from('kelas b');
        $this->db->join('siswa_kelas c', 'c.namakelas= b.namakelas', 'c.thnakademik=b.thnakademik', 'c.kdtingkat=b.kdtingkat', 'right');
        $this->db->like('nik',$data1['hasil1']);
        $data = $this->db->get(); //mengambil seluruh data
        return $data->result();
    }

我希望它会有所帮助。
