[英]blueimp jQuery File Upload PHP MySQL database integration third textfield
[英]jquery file upload php database blueimp
我正在使用此插件,我一直在尋找有關它的大量信息,並希望對我有所幫助。 1)當傳遞超過5000個文件時,不再生成jsone。關於此,我正在嘗試通過數據庫ID進行調用,但仍然無法獲取例如fotos.php? Id = 1,並且僅生成該查詢的json。2)Update更新數據庫中已存在的數據
這是我的php文件,位於/server/php/index.php
class CustomUploadHandler extends UploadHandler {
protected function initialize() {
$this->db = new mysqli(
$this->options['db_host'],
$this->options['db_user'],
$this->options['db_pass'],
$this->options['db_name']
);
parent::initialize();
$this->db->close();
}
protected function handle_form_data($file, $index) {
$file->title = @$_REQUEST['title'][$index];
$file->description = @$_REQUEST['description'][$index];
$file->padre = @$_REQUEST['padre'][$index];
}
protected function handle_file_upload($uploaded_file, $name, $size, $type, $error,
$index = null, $content_range = null) {
$file = parent::handle_file_upload(
$uploaded_file, $name, $size, $type, $error, $index, $content_range
);
if (empty($file->error)) {
$sql = 'INSERT INTO `'.$this->options['db_table']
.'` (`ruta_adjunto`, `id_documento`, `tipo_adjunto`, `nombre_adjunto`, `descripcion_adjunto`)'
.' VALUES (?, ?, ?, ?, ?)';
$query = $this->db->prepare($sql);
$query->bind_param(
'sisss',
$file->name,
$file->padre, //id_documento luego ver como traer el id
$file->type,
$file->title,
$file->description
);
$query->execute();
//echo json_encode($query->error);
$file->id_adjunto = $this->db->insert_id;
}
return $file;
}
protected function set_additional_file_properties($file) {
parent::set_additional_file_properties($file);
if ($_SERVER['REQUEST_METHOD'] === 'GET') {
$sql = 'SELECT `id_adjunto`, `id_documento`, `ruta_adjunto`, `nombre_adjunto`, `descripcion_adjunto` FROM `'
.$this->options['db_table'].'` WHERE `ruta_adjunto`=?';
$query = $this->db->prepare($sql);
$query->bind_param('s', $file->name);
$query->execute();
$query->bind_result(
$id_adjunto,
$id_documento,
$titulo_documento,
$descripcion_documento
);
while ($query->fetch()) {
$file->id = $id_adjunto;
//$file->type = $type;
$file->padre = $id_documento;
$file->title = $titulo_documento;
$file->description = $descripcion_documento;
}
}
}
public function delete($print_response = true) {
$response = parent::delete(false);
foreach ($response as $name => $deleted) {
if ($deleted) {
$sql = 'DELETE FROM `'
.$this->options['db_table'].'` WHERE `ruta_adjunto`=?';
$query = $this->db->prepare($sql);
$query->bind_param('s', $name);
$query->execute();
}
}
return $this->generate_response($response, $print_response);
}
}
$ upload_handler =新的CustomUploadHandler($ options);
所以我在文件upload.html中
{% for (var i=0, file; file=o.files[i]; i++) { %}
<tr class="template-upload fade">
<td>
<span class="preview"></span>
</td>
<td>
<label class="title">
<span>Nombre:</span><br>
<input name="title[]" class="form-control">
</label>
</td>
<td>
<label class="description">
<span>Descripcion:</span><br>
<input name="description[]" class="form-control">
</label>
<input name="padre[]" value="<?php echo $_GET['id'];?>" class="form-control">
</td>
<td>
<p class="name">{%=file.name%}</p>
<strong class="error text-danger"></strong>
</td>
<td>
<p class="size">Procesando...</p>
<div class="progress progress-striped active" role="progressbar" aria-valuemin="0" aria-valuemax="100" aria-valuenow="0"><div class="progress-bar progress-bar-success" style="width:0%;"></div></div>
</td>
<td>
{% if (!i && !o.options.autoUpload) { %}
<button class="btn btn-primary start" disabled>
<i class="glyphicon glyphicon-upload"></i>
<span>Comenzar</span>
</button>
{% } %}
{% if (!i) { %}
<button class="btn btn-warning cancel">
<i class="glyphicon glyphicon-ban-circle"></i>
<span>Cancelar</span>
</button>
{% } %}
</td>
</tr>
{%}%}
這里一些參考
雖然我認為這不是最佳解決方案,但請使用文件服務器/php/UploadHandler.php的user_dirs
在這條線上像這樣
'user_dirs' => true,
在upload.html文件中
session_start(); $_SESSION['father'] = $_GET['id'];
並在/server/php/index.php中
protected function get_user_id() {
@session_start();
foreach( $_SESSION as $key=>$father ) {
$username = $father;
}
return $username;
#return session_id();
}
它的作用是將ID作為會話傳遞,從而查看分配的文件夾。
當我有一個將所有文件放在一起的文件夾時,制作一個小腳本,該腳本將生成一個帶有文件ID號的文件夾
<?php
require_once('../inc/conexion.php');
$ db = db :: getInstance();
$ res = $ db-> query(“ SELECT * FROM adjuntos LIMIT 2000”);
$ ruta ='../admin/server/php/files/';
while($ reg = $ res-> fetch_array()){
if(file_exists($ruta.$reg['id_documento'])){
$origen = '../pdfs/'.$reg['ruta_adjunto'];
$destino = $ruta.$reg['id_documento'].'/'.$reg['ruta_adjunto'];
if(!copy($origen, $destino)){
echo 'error al copiar el archivo del id: '.$reg['id_documento'];
}
}else{
$carpeta = $ruta.$reg['id_documento'];
if(!mkdir($carpeta, 0777, true)){
echo 'Error al crear la CARPETA CON ID: '.$reg['id_documento'];
}else{
$origen = '../pdfs/'.$reg['ruta_adjunto'];
$destino = $ruta.$reg['id_documento'].'/'.$reg['ruta_adjunto'];
if(!copy($origen, $destino)){
echo 'error al copiar el archivo del id: '.$reg['id_documento'];
}
}
}
}?>
