codeigniter将多个图像添加到单个产品并插入数据库

标签： php mysql image codeigniter upload

我想将多个图像添加到单个产品中，并将所有图片名称插入数据库。现在我只能将一个图像上传并存储到数据库中，但仍然无法找到上传多个图像的方法。

我不确定在哪里放置循环以及循环应包含的内容。

以下是我插入单张图片的代码：

控制器：

public function coba(){

            $uploadPath = realpath('./assets/images/test/');

        chmod($uploadPath, 0777);

        $nama_array = array();
        $count = count($_FILES["gambar"]["size"]);

        foreach($_FILES as $k=>$v)

            for($i = 0; $i <= $count-1; $i++) {
                $nama = $v["name"][$i];

                $config["upload_path"] = $uploadPath;
                $config["allowed_types"] = "jpg|png|jpeg";
                $config["overwrite"] = true;
                $config["remove_spaces"] = true;
                $config["max_size"] = 600;
                $config["max_width"] = 800;
                $config["max_height"] = 600;

                $this->load->library("upload", $config);

                $this->upload->do_upload("gambar[$i]");
                $image_data = $this->upload->data();
                $nama_array[] = $image_data["file_name"];
                echo $nama . "<br>";
            }

        $names = implode(",", $nama_array);
        print_r($nama_array);
        echo "<br>" . $count . "<br>";
        echo "sukses";

    }

观点：

<html>
<head>

</head>

<body>

                            <?php 
                                echo form_open_multipart("admin/coba");

                                echo "<p>";
                                echo form_upload("gambar");
                                echo "</p>";

                                echo form_submit("formSubmit", "Insert Product"); 

                            ?>
</body>
</html>

带调整大小的库：

        $CI->load->library('upload', $config);

        $CI->upload->initialize($config);

        $no = count($new_file['name'])-1; 

        $file= $_FILES;

        for ($i=0; $i <= $no ; $i++)
        {
            //echo $file['files']['name'][$i]; exit;
            $_FILES['files']['name']=$file['files']['name'][$i];

            if ($CI->upload->do_upload('files'))
            {
                $other_images = $CI->upload->data();
                $othimage[] = $other_images['file_name'];

使用以下代码作为示例

public function add() {
    $this->load->library(array('form_validation', 'myupload'));
   //print_r($_FILES);exit;
    if ($this->input->post('btnSubmit') == 'Submit') {

        $this->form_validation->set_rules('title', 'Title', 'required|trim');
        $this->form_validation->set_rules('content', 'Content', 'required|trim');


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

            $insertData = array(
                'title' => $this->input->post("title"),
                'content' => $this->input->post("content"),
            );
            if ($portfolioId = $this->portfolio_model->add($insertData)) {
                if (isset($_FILES) && $image = $this->myupload->uploadFile($_FILES, 'portfolio')) {


                    if (isset($image['error']) && $image['error']) {
                        echo $image['error'];
                        echo "Click <a href='" . base_url() . "admin/portfolio'>here</a> to go back";
                        exit;
                    } else {
                        foreach ($image as $img) {
                            $portfolioImage[] = array(
                                'images' => $img,
                                'portfolio_id' => $portfolioId
                            );
                        }
                    }
                }

                if ($portfolioId = $this->portfolio_model->add_images($portfolioImage)) {
                    $this->session->set_flashdata("success", "Portfolio added successfully");
                } else {
                    $this->session->set_flashdata("error_message", "Portfolio was not added!!");
                    $this->session->set_flashdata('data', $this->input->post());
                }
            } else {
                $this->session->set_flashdata("error_message", "Portfolio was not added!!");
                $this->session->set_flashdata('data', $this->input->post());
            }
        } else {

            $this->session->set_flashdata('error_message', validation_errors());
        }
        redirect("admin/portfolio");
    }
}

并创建一个名为Myupload.php的库并粘贴到代码下面 更新图片调整大小的代码

我的型号代码

public function add($insertData) {
        if ($this->db->insert('portfolio', $insertData))
            return $this->db->insert_id(); //give last insert id
    }


    public function add_images($insertData) {
        if ($this->db->insert_batch('portfolio_image', $insertData)) {
            return TRUE;
        }
    }

答案 2 :(得分：0)

我已经用自己的方法破解了这个，但代码非常混乱，我甚至很难理解代码工作后，需要学习更多更简单有效的代码，

这是我的代码：

控制器：

$this->load->library("myupload", "form_validation");
        $this->load->model("testModel");
        $barangImage = array();
        $hitung = 0;

        if($this->input->post("formSubmit")) {
            $this->form_validation->set_rules("nama", "Nama", "required|trim");

            if($this->form_validation->run()) {
                $insertData = array(
                    "nama" => $this->input->post("nama")
                );
                if($id = $this->testModel->add($insertData)) {

                    print_r($id);
                    $barangImage = array(
                            "barangid" => $id["id"]
                    );

                    if(isset($_FILES) && $image = $this->myupload->uploadFile($_FILES)) {

                        if(isset($image["error"]) && $image["error"]) {
                            echo $image["error"];
                        }else {
                            foreach($image as $img) {
                                ++$hitung;
                                $barangImage[] = array(
                                        "gambar" => $img,
                                        "barangid" => $id
                                );

                            }
                            print_r($barangImage);
                        }
                    }

                    if($id = $this->testModel->add_images($barangImage, $hitung)) {
                        echo "SUCCESS !!!";
                    }else {
                        echo "FAIL INSERT IMAGES!!!";
                    }
                }else {
                    echo "FAIL INSERT DATA NAMA";
                }
            }else {
                echo "FAIL VALIDASI RUN";
            }
        }

型号：

public function add($newData){
        $this->db->insert("cobabarang", $newData);

        $nama = $newData["nama"];
        $id = $this->db->query("SELECT id FROM cobabarang WHERE nama = \"$nama\"");

        return $id->row_array();
        //return $this->db->insert_id();
    }

    public function add_images($newImage, $banyakData) {
        $id;
        $gambar = null;
        //$this->db->insert("cobagambar", $newImage);
        if(count($newImage) != 1) {
            $id = $newImage[0]["barangid"]["id"];
            $gambar = null;

            for($i = 0; $i < $banyakData; $i++){
                if($banyakData-$i == 1) {
                    $gambar .= $newImage[$i]["gambar"];
                }else {
                    $gambar .= $newImage[$i]["gambar"] . ",";
                }
            }
        }else {
            $id = $newImage["barangid"];
        }

        //$gambar = $newImage[1]["gambar"];

        $this->db->query("INSERT INTO cobagambar(barangid, gambar) VALUES($id, \"$gambar\")");
    }
