我有输入表格。这个表单的输入非常复杂，因为一个表单被提交到数据库中的三个以上的表。
我想在我的表单中添加上传图片，但我不知道我应该把它放在哪里。< br />
这是 控制器 的输入

$data['np_lain'] = $np_lain;
$this->db->insert('input_pen', $data);
$this->db->trans_complete();
return $this->db->insert_id();
}
我上传的图片的链接应该在$data数组中。
我不知道该怎么办。谁能举个例子？

此脚本会将您的文件上传到目标文件夹mkdir($config['upload_path'], 0777, TRUE);
Param number 3，TRUE将为您递归创建目录。
相应的行将放置数据库的名称和路径
$post_data = array(
'name' => $_FILES["__INPUT__FIELD__NAME"]['name'],
'path' => $hook
);
$this->db->insert('FILES__DB__', $post_data);
通用用法
File_handler模型
<?PHP
if (!defined('BASEPATH'))
exit('No direct script access allowed');
class File_handler extends CI_Model {
private $base_p = "./files/";
private $ext = 'pdf|csv|doc|txt';
private $size = 5000000;
function _push_file($path, $name) {
// make sure it's a file before doing anything!
if (is_file($path)) {
// required for IE
if (ini_get('zlib.output_compression')) {
ini_set('zlib.output_compression', 'Off');
}
// get the file mime type using the file extension
$this->load->helper('file');
$mime = get_mime_by_extension($path);
// Build the headers to push out the file properly.
header('Pragma: public'); // required
header('Expires: 0'); // no cache
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Last-Modified: ' . gmdate('D, d M Y H:i:s', filemtime($path)) . ' GMT');
header('Cache-Control: private', false);
header('Content-Type: ' . $mime); // Add the mime type from Code igniter.
header('Content-Disposition: attachment; filename="' . basename($name) . '"'); // Add the file name
header('Content-Transfer-Encoding: binary');
header('Content-Length: ' . filesize($path)); // provide file size
header('Connection: close');
readfile($path); // push it out
exit();
}
}
public function fsize($s) {
$this->size = $s;
}
public function fext($ext) {
$this->ext = $ext;
}
public function upload_file($field, $subpath) {
if (!empty($_FILES[$field]['name'])) {
$config['upload_path'] = $this->base_p . '' . $subpath;
$config['allowed_types'] = $this->ext;
$config['max_size'] = $this->size; // 5 mb
$config['encrypt_name'] = TRUE;
if (!is_dir($config['upload_path'])) {
mkdir($config['upload_path'], 0777, TRUE);
}
$this->load->library('upload', $config);
if (!$this->upload->do_upload($field)) {
$status = 'error';
$msg = $this->upload->display_errors('', '');
return json_encode(array('result' => 'error', 'msg' => $msg));
die();
} else {
$data = $this->upload->data();
}
return $path = 'files' . $subpath . '/' . $data['file_name'];
}
}
}
在逻辑模型中使用
$this->load->model("File_handler", "fh");
$this->fh->fext("jpg|jpeg|pdf|png");
$hook = $this->fh->upload_file("__INPUT__FIELD__NAME", "__PATH__TO__UPLOAD");
// Errors from File_handler controller
if (isset(json_decode($hook)->result) && json_decode($hook)->result == "error") {
$message = json_decode($hook)->msg;
}
// If we got the path all is ok
if ($hook) {
$post_data = array(
'name' => $_FILES["__INPUT__FIELD__NAME"]['name'],
'path' => $hook
);
$this->db->insert('FILES__DB__', $post_data);
$fid = $this->db->insert_id();
if (!is_numeric($fid)) {
$message = "Error, file not added";
}
}
if (strlen($message) == 0) {
// No errors in the file handler
// get your upload url path with file name from $hook
}else{
echo $message;
}.
在你的情况下：
您需要在数据库中创建一个使用此架构的表
CREATE TABLE `file_uploads` (
`id` bigint(20) NOT NULL,
`name` varchar(100) COLLATE utf8_unicode_ci NOT NULL,
`time_added` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
`path` varchar(200) COLLATE utf8_unicode_ci NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;
--
-- Indexes
--
ALTER TABLE `file_uploads`
ADD PRIMARY KEY (`id`);
--
-- AUTO_INCREMENT
--
ALTER TABLE `file_uploads`
MODIFY `id` bigint(20) NOT NULL AUTO_INCREMENT;COMMIT;
您的模型
function m_submit($data, $datakon, $datakoor, $datalahan, $dataprod, $datavar, $datalok, $datappadi, $datapjagung, $datapked, $dataplain) {
$this->db->trans_start();
$this->db->insert('koor_pen', $datakoor);
$no_koor = $this->db->insert_id();
$this->db->insert('kontak', $datakon);

// If we got the path all is ok

'path' => $hook
);

$message = "Error, file not added";

if (strlen($message) == 0) {

$this->db->trans_complete();

需要注意的事项HTML
您需要将表单enctype =＆＃34; multipart / form-data＆＃34;
<form id="FormId" name="Formname" method="post" enctype="multipart/form-data" accept-charset="utf-8">
输入类型文件
<input type="file" class="form-control" name="foto" id="foto">
jquery ajax处理的代码示例
$.ajax({
url: '<?PHP echo base_url(); ?>CONTROLLER/FUNCTION',
type: "POST",
mimeType: "multipart/form-data",
contentType: false,
dataType: 'json',
cache: false,
processData: false,
data: $form.serialize(),
success: function (data) {
// Your logic
}
});
答案 1 :(得分：0)
首先让我们清除代码
对于提交sevral表单，您可以轻松地在html名称标签中使用用户数组
<input name="datakon[no_kon]" >
<input name="datakon[jab]" >
<input name="datakon[namakon]" >
<input name="datakon[telp]" >
在Controller端，您可以将它们插入数据库中一行
$datakon = $this->input->post('datakon');
$this->db->insert('kontak', $datakon);
$no_kon = $this->db->insert_id();
如果您的数据库表名与输入字段相同，则完成
现在让我们开始上传文件
您不应该上传数据库中的文件。
而不是将文件上传到数据库，您可以将文件升级到目录并保存该目录地址。
要上传文件，您可以使用codeigniter上传库Codeigniter Upload File Documentation
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload('no_kon'))
{
$error = array('error' => $this->upload->display_errors());
$this->load->view('upload_form', $error);
}
else
{
$data = array('upload_data' => $this->upload->data());
$this->load->view('upload_success', $data);
}
