文件上传的opencart代码

Question

我是Opencart新手，真的很厉害

我只想在数据库中插入一张图片，但无法上传。这是我所做的。

模板：

<div class="col-sm-10">
    <img src="" name="image" id="image" style="width: 26%;height: 100px;" >
    <input type="file" 
           name="photo" 
           value="<?php echo $photo; ?>" 
           placeholder="<?php echo $entry_photo; ?>" 
           id="photo" 
           onChange="PreviewImages();"/>
    <?php if ($error_photo) { ?>
    <div class="text-danger"><?php echo $error_photo; ?></div>
    <?php } ?>
</div>

控制器：

if (is_uploaded_file($this->request->files['photo']['tmp_name'])) {
    $handle = fopen($this->request->files['photo']['tmp_name'], "r");

    // If we know there is only a 10 chars PIN per line 
    // it is better to lower the expected line length 
    // to lower the memory consumption...
    while (($pins = fgetcsv($handle, 50, ",")) !== false) { 
        $data['photo'][] = $pins; // there is only one PIN per line
    }
    fclose($handle);
} else {
    $data['photo'] = array();
}

型号：

$this->db->query("
    INSERT INTO " . DB_PREFIX . "customer 
    SET customer_group_id = '" . (int)$customer_group_id . "', 
        store_id = '" . (int)$this->config->get('config_store_id') . "', 
        firstname = '" . $this->db->escape($data['firstname']) . "', 
        lastname = '" . $this->db->escape($data['lastname']) . "',
        photo = '" . $this->db->escape($data['photo']) . "',
        date = '" . $this->db->escape($data['date']) . "',
        email = '" . $this->db->escape($data['email']) . "',
        telephone = '" . $this->db->escape($data['telephone']) . "',
        fax = '" . $this->db->escape($data['fax']) . "',
        custom_field = '" . $this->db->escape(isset($data['custom_field']['account']) ? serialize($data['custom_field']['account']) : '') . "',
        salt = '" . $this->db->escape($salt = substr(md5(uniqid(rand(), true)), 0, 9)) . "',
        password = '" . $this->db->escape(sha1($salt . sha1($salt . sha1($data['password'])))) . "',
        newsletter = '" . (isset($data['newsletter']) ? (int)$data['newsletter'] : 0) . "',
        ip = '" . $this->db->escape($this->request->server['REMOTE_ADDR']) . "',
        status = '1',
        approved = '" . (int)!$customer_group_info['approval'] . "',
        date_added = NOW()
");
$customer_id = $this->db->getLastId();

您没有提到您要在哪个页面上传，但不要忘记在上传时在表单中添加 enctype="multipart/form-data"。

if (is_uploaded_file($this->request->files['photo']['tmp_name'])) {
$handle = fopen($this->request->files['photo']['tmp_name'], "r");

// If we know there is only a 10 chars PIN per line 
// it is better to lower the expected line length 
// to lower the memory consumption...
while (($pins = fgetcsv($handle, 50, ",")) !== false) { 
    $data['photo'][] = $pins; // there is only one PIN per line
}
fclose($handle);
} else {
$data['photo'] = array();
}

请用以下代码替换上面的代码：

$data['photo'] = '';
$uploads_dir = 'image/data/'; // set you upload path here
if (is_uploaded_file($this->request->files['photo']['tmp_name'])) {

    move_uploaded_file($this->request->files['photo']['tmp_name'],$uploads_dir.$this->request->files['photo']['name']);
  $data['photo'] = $this->request->files['photo']['name'];
}

来自

$json['code'] = $this->model_tool_upload->addUpload($filename, $file);

到
