Cocos2dx demo for uploading simple files to the php server

Recently I just finished writing a simple test program that uploads data from the client to the php server. The code can be copied and run directly. before reading the code, it is best to spend some time learning about php and libcurl, it won't take too long. Because I am not very familiar with php when I create a form, all the libcurl

I have just finished writing a cocos2dx file and uploaded it from the client to php.ServerOfSimpleTest Program, code can be copied and run directly

Before reading the code, it is best to take some time to learn about php and libcurl. It does not take too long because I am not very familiar with php, it took me a while to solve a problem when I pieced the form using libcurl. The code below isSimpleThe demo code is a bit rough, but it has little impact on everyone's understanding.

I use Apache in XAMMPServer, Put the php script in the \ xampp \ htdocs \ directory, and create upload in the current directoryFileFolder used to store the uploadedFile

1:

ReceiveFile. php

 File*/$ Type = array ("rar", "zip", "txt", "c", "JPG");/* obtain the uploadFileInformation * // $ upfile = & $ HTTP_POST_FILES ['file']; $ upfile = $ _ FILES ["file"]; echo "Upload :". $ _ FILES ["file"] ["name"]."
"; Echo" Type: ". $ _ FILES [" file "] [" type "]."
& Quot; echo & quot; Size: & quot;. ($ _ FILES [& quot; file & quot;] [& quot; size & quot;]/1024). & quot; Kb
"; Echo" Temp file: ". $ _ FILES [" file "] [" tmp_name "]."
";/* GetFileExtension name function */function fileext ($ filename) {return substr (strrchr ($ filename ,'. '), 1);} // echo "Temp file :". fileext ($ upfile ['name']."
";/* Determine the uploadFileType */if (! In_array (strtolower (fileext ($ upfile ['name']), $ type) {$ text = implode (",", $ type); echo "sorry, you can only upload the following typesFile: ", $ Text ,"
";} Else {/* settingsFileName: "date _FileName "*/$ dest = $ dest_dir. '/'. date (" ymdHis ")." _ ". $ upfile ['name'];/* Move uploadFileTo specifiedFileFolder */$ state = move_uploaded_file ($ upfile ['tmp _ name'], $ dest); if ($ state) {print ("FileUploaded successfully!
"); Print ("FileName: ". $ dest ."
"); Print (" uploadedFileSize: ". (round ($ upfile ['SIZE']/, 2)." KB
");} Else {/* handle error messages */switch ($ upfile ['error']) {case 1: die (" UploadFileThe size exceeds the limit of php. ini: upload_max_filesize.
"); Case 2: die (" UploadFileThe size exceeds the MAX_FILE_SIZE limit.
"); Case 3: die ("FileOnly partially uploaded
"); Case 4: die (" NoFileUploaded
"); Case 5: die (" cannot find temporaryFileClip
"); Case 6: die ("FileWrite failed
") ;}}?>

Upload.html form:

You can directly run upload.html, such as http: // 127.0.0.1/WD/upload.html.

The page appears. Select the correspondingFileUpload will prompt

Note: The php page will have a size limit of more than 1 MB.

Next, we need to use the libcurl libraryImplementationUpload.html form,ImplementationUpload function

The above code isSimpleThe demo code is quite rough, but it should not affect everyone's understanding. There is still a lot of room for optimization in the code. You can optimize and expand the space. We hope you can complete it together!
