我有一個腳本來上傳文件使用codeigniter,但它仍然使用提交按鈕。我想上傳而不點擊提交。這是我的腳本:如何在沒有提交按鈕的情況下在codeigniter中上傳文件?
控制器/ gallery.php
<?php
class Gallery extends CI_Controller{
public function __construct()
{
parent::__construct();
}
function index(){
$this->load->model('MGallery');
if($this->input->post('upload')){
$this->MGallery->do_upload();
}
$this->load->view('gallery_view');
}
}
?>
型號/ mgallery.php
<?php
class MGallery extends CI_Model{
var $gallery_path;
public function __construct()
{
parent::__construct();
$this->gallery_path = realpath(APPPATH . '../images');
}
function do_upload(){
$config = array(
'allowed_types'=>'jpg|jpeg|gif|png',
'upload_path' => $this->gallery_path,
'max_size' => 2000
);
$this->load->library('upload',$config);
$this->upload->do_upload();
$image_data = $this->upload->data();
$config = array(
'source_image'=> $image_data['full_path'],
'new_image'=>$this->gallery_path . '/thumbs',
'maintain_ration'=>true,
'width'=>160,
'height'=>120
);
$this->load->library('image_lib', $config);
$this->image_lib->resize();
}
}
*意見/ gallery_view.php *
<!DOCTYPE HTML>
<html lang="en-US">
<head>
<title>Gallery With CI</title>
<meta charset="UTF-8">
</head>
<body>
<div id="gallery">
</div>
<div id="upload">
<?php echo form_open_multipart('gallery'); ?>
<?php echo form_upload('userfile');?>
<?php echo form_submit('upload','Upload'); ?>
<?php echo form_close(); ?>
</div>
</body>
如果我想讓它上傳而不提交按鈕,我該怎麼辦?
你會給我更詳細的腳本在每個模型,視圖,控制器? 我已經嘗試上面的解決方案,但我上傳的圖像沒有存儲在目標文件夾中。 對不起,我還是新手.. – dyn
