我目前編碼的網站的一部分，允許用戶上傳圖像，然後選擇該圖像的區域進行裁剪。我想要它，以便該圖像上傳時用戶不必提交表單，所以我使用一個名爲swfupload的工具，我設法獲取圖像上傳，但是我無法獲得swfupload來創建縮略圖，甚至無法讀取我的縮略圖方法。codeigniter圖像上傳和調整大小 - swfupload
下面是我的代碼，
PHP
public function upload()
{
$config['upload_path'] = "./media/uploads/users";
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '1000';
$config['max_width'] = '1024';
$config['max_height'] = '768';
$config['encrypt_name'] = TRUE;
$this->load->library('upload', $config);
if (! $this->upload->do_upload('Filedata'))
{
$error = array('error' => $this->upload->display_errors());
//die(print_r($error));
}
else
{
$this->file = $this->upload->data();
echo $this->file['file_name'];
}
}
public function thumbnail()
{
//lets just try and get thumbnail() talking to swfupload
echo 1;
}
SWFUpload的JS
window.onload = function() {
swfu = new SWFUpload({
// Backend Settings
upload_url: "http://lcl.moovjob.com/index.php/admin/users/upload",
post_params: {"PHPSESSID": "<?php echo $this->session->userdata('session_id'); ?>" },
// File Upload Settings
file_size_limit : "5 MB", // 5MB
file_types : "*.jpg",
file_types_description : "JPG Images",
file_upload_limit : "0",
// Event Handler Settings - these functions as defined in Handlers.js
// The handlers are not part of SWFUpload but are part of my website and control how
// my website reacts to the SWFUpload events.
file_queue_error_handler : fileQueueError,
file_dialog_complete_handler : fileDialogComplete,
upload_progress_handler : uploadProgress,
upload_error_handler : uploadError,
upload_success_handler : uploadSuccess,
upload_complete_handler : uploadComplete,
// Button Settings
button_image_url : "images/SmallSpyGlassWithTransperancy_17x18.png",
button_placeholder_id : "spanButtonPlaceholder",
button_width: 180,
button_height: 18,
button_text : '<span class="button">Select Images <span class="buttonSmall">(2 MB Max)</span></span>',
button_text_style : '.button { font-family: Helvetica, Arial, sans-serif; font-size: 12pt; } .buttonSmall { font-size: 10pt; }',
button_text_top_padding: 0,
button_text_left_padding: 18,
button_window_mode: SWFUpload.WINDOW_MODE.TRANSPARENT,
button_cursor: SWFUpload.CURSOR.HAND,
// Flash Settings
flash_url : "/media/flash/swfupload.swf",
custom_settings : {
upload_target : "divFileProgressContainer"
},
// Debug Settings
debug: true
});
};
我的處理程序JS，尤其是上傳成功的方法，
function uploadSuccess(file, serverData) {
try {
var progress = new FileProgress(file, this.customSettings.upload_target);
if (serverData.substring(0, 7) === "FILEID:") {
addImage("http://local.test.com/index.php/admin/users/thumbnail");
progress.setStatus("Thumbnail Created.");
progress.toggleCancel(false);
} else {
addImage("images/error.gif");
progress.setStatus("Error.");
progress.toggleCancel(false);
alert(serverData);
}
} catch (ex) {
this.debug(ex);
}
}
什麼時我爲此而做所有我想要的圖像都是上傳的，然後返回1，所以我知道swfupload正在與我的控制器通話。我回來的是上傳成功或錯誤。
