Question

我正在尝试上传包含汽车品牌，年份，租赁和付款数据的图片以及图片上传。我的图像路径也插入到数据库中，但我仍然无法想象如何将两者结合起来。我得到error Array to string conversion并且没有输入我的数据和图片上传。

汽车表：

car_make | car_model | car_year | car_lease | car_payment | imgpath
acura    | G37 Sedan |   2009   |  48       |   350       |  assets/images/acura_1.jpg

控制器：

public function car_validation_do_upload() {

        $this->load->library('form_validation');


        $this->form_validation->set_rules('car_make', 'Car Make', 'required');
        $this->form_validation->set_rules('car_model', 'Car Model', 'required');
        $this->form_validation->set_rules('car_year', 'Car Year', 'required');
        $this->form_validation->set_rules('car_lease', 'Car Lease', 'required');
        $this->form_validation->set_rules('car_payment', 'Car Payment', 'required');

        if($this->form_validation->run() == TRUE) {

            $config['upload_path'] = './assets/images/';
            $config['allowed_types'] = 'gif|jpeg|jpg|png';
            $this->load->library('upload', $config);




            $newRow = array("car_make" => $this->input->post('car_make'),
                        "car_model" => $this->input->post('car_model'),
                        "car_year" => $this->input->post('car_year'),
                        "car_lease" => $this->input->post('car_lease'),
                        "car_payment" => $this->input->post('car_payment'));

            $data = array('upload' => $this->upload->data());

            $result = array_merge($newRow, $data);

        $this->load->model("model_users");

        $this->model_users->insert1($result);   
        $this->session->set_flashdata('message', 'car inserted into database!');
        redirect('main/insertCar');


    }


    else {
    $this->load->view('insert_car');
    }


    }


Model:
public function insert1($data) {

        $this->db->insert("cars", $data);
        }

View
<?php 

    //echo form_open('main/car_validation_insert');
    echo form_open_multipart('main/car_validation_do_upload');  
        echo validation_errors();

        if($this->session->flashdata('message')){
  echo $this->session->flashdata('message');
  }
    ?>

    <table width="504" style="margin-left:15px;">

改变这个：

$data = array('upload' => $this->upload->data());

$result = array_merge($newRow, $data);

对此：

  if ($this->upload->do_upload()){
    $image_data = $this->upload->data();
    //this will create a new key with the name upload in your newRow
    //so theres no need to use the function array_merge
    $newRow['imgpath'] ='assets/images/'.$image_data['file_name'];
}
else{
    //do something here
    echo 'error uploading image'
}

$ image_data变量将包含有关您上传图片的信息

 Array
(
    [file_name]    => mypic.jpg
    [file_type]    => image/jpeg
    [file_path]    => /path/to/your/upload/
    [full_path]    => /path/to/your/upload/jpg.jpg
    [raw_name]     => mypic
    [orig_name]    => mypic.jpg
    [client_name]  => mypic.jpg
    [file_ext]     => .jpg
    [file_size]    => 22.2
    [is_image]     => 1
    [image_width]  => 800
    [image_height] => 600
    [image_type]   => jpeg
    [image_size_str] => width="800" height="200"
)
