Swfupfile uploaded with multiple images

 

Not to mention nonsense ,:

Uploaded files are automatically added to the database.

Usage:

Add in the header of the page to be uploaded (CSS, images, and JS should also be copied in)

<Link href = "css.css" rel = "stylesheet" type = "text/CSS"/> <SCRIPT type = "text/JavaScript" src = "swfupload/swfupload. JS "> </SCRIPT> <SCRIPT type =" text/JavaScript "src =" JS/swfupload. queue. JS "> </SCRIPT> <SCRIPT type =" text/JavaScript "src =" JS/fileprogress. JS "> </SCRIPT> <SCRIPT type =" text/JavaScript "src =" JS/filegroupprogress. JS "> </SCRIPT> <SCRIPT type =" text/JavaScript "src =" JS/handlers. JS "> </SCRIPT> <SCRIPT type =" text/JavaScript "> var swfu; window. onload = function () {var settings = {flash_url: "swfupload/swfupload.swf", upload_url: "imgupload. ashx ", // data submission and processing page file_size_limit:" 2 MB ", // size limit file_types :"*. jpg ", // file_types_description:" JPG images ", // JPG file file_upload_limit: 100, limit: 0, custom_settings: {progresstarget:" divprogresscontainer ", progressgrouptarget: "divprogressgroup", // progress object container_css: "progressobj", progress: "iconormal", icowaiting_css: "icowaiting", progress: "icoupload", fname_css: "fle ftt ", state_div_css: "statebarsmalldiv", state_bar_css: "statebar", percent_css: "FTT", href_delete_css: "FTT ", // elements declared starting with "CNT _" */s_cnt_progress: "cnt_progress", s_cnt_span_text: "FLE", s_cnt_progress_statebar: "cnt_progress_statebar ", s_cnt_progress_percent: "cnt_progress_percent", progress: "progress", s_cnt_progress_size: "cnt_progress_size"}, debug: false, // button settings button_image_url: "images/progress", button_width: "65", button_height: "29", button_placeholder_id: "spanbuttonplaceholder", button_text: '<SPAN class = "thefont"> Upload File </span>', button_text_style :". thefont {font-size: 12; color: #0068b7;} ", button_text_left_padding: 12, button_text_top_padding: 3, // The event handler functions are defined in handlers. JS Plugin: filequeued, Handler: filequeueerror, upload_start_handler: uploadstart, Handler: uploadprogress, Handler: uploaderror, Handler: uploadsuccess, Handler: uploadcomplete, Handler: filealodigcomplete }; swfu = new swfupload (settings) ;}; </SCRIPT>

 

Put the following code in the specific place to upload

 

<span id="spanButtonPlaceHolder"></span><div id="divprogresscontainer">  </div> <div id="divprogressGroup"> </div>

 

Add a general processing program (imgupload. ashx) to store uploaded images to the database.

<% @ Webhandler Language = "C #" class = "imgupload" %> using system; using system. collections. generic; using system. web; using system. io; public class imgupload: ihttphandler {public void processrequest (httpcontext context) {If (context. request. cookies ["user"] = NULL) {jiangs_tools.show_msg ("Please log on again");} Try {httppostedfile file; For (INT I = 0; I <context. request. files. count; ++ I) {file = context. request. files [I]; If (file = NULL | file. contentlength = 0 | string. isnullorempty (file. filename) continue; file. saveas (httpcontext. current. server. mappath ("uploadfile/" + path. getfilename (file. filename); // Save the image string newname = sjname () + path. getextension (file. filename); // generate a new name file. move (context. server. mappath ("uploadfile/" + path. getfilename (file. filename), context. server. mappath ("uploadfile/" + newname); // rename jiang_db newdb = new jiang_db (); newdb. open (); newdb. execsql (string. format ("insert into [img] ([name], [img], [member_id]) values ('{0}', '{1 }', '{2}') ", // saved to the database path. getfilenamewithoutextension (file. filename), "/uploadfile/" + newname, context. request. cookies ["user"] ["ID"]); newdb. close (); // file. appendalltext (context. server. mappath ("filename.txt"), file. filename + "new name:" + newname + environment. newline) ;}} catch (exception ex) {context. response. status Code = 500; context. response. write (ex. message); context. response. end ();} finally {context. response. end () ;}} public bool isreusable {get {return false ;}} /// <summary> /// generate a prompt name /// </Summary> /// <returns> </returns> Public String sjname () {string SJ = NULL; SJ = datetime. now. year. tostring () + datetime. now. month. tostring () + datetime. now. day. tostring () + datetime. now. timeofday. hours. tostring () + datetime. now. timeofday. minutes. tostring () + datetime. now. timeofday. milliseconds. tostring (); Return SJ ;}}
