Backend php code

<? Php // upload $ upsize here to determine the size of the uploaded file $ uppath = "/attached/"; // File Upload path // convert the root directory path if (strpos ($ uppath, "/") = 0) {$ I = 0; $ thpath = $ _ SERVER ["SCRIPT_NAME"]; $ thpath = substr ($ thpath, 1, strlen ($ thpath); while (strripos ($ thpath ,"/")! = False) {$ thpath = substr ($ thpath, strpos ($ thpath, "/") + 1, strlen ($ thpath )); $ I = ++ $ I;} $ pp = ""; for ($ j = 0; $ j <$ I; ++ $ j) {$ pp. = ".. /";}$ uppaths = $ pp. substr ($ uppath, 1, strlen ($ thpath);} $ filename = date ("y-m-d"); if (is_dir ($ uppaths. $ filename )! = TRUE) mkdir ($ uppaths. $ filename, 0777); $ f = $ _ FILES ['pic ']; if ($ f ["type"]! = "Image/gif" & $ f ["type"]! = "Image/pjpeg" & $ f ["type"]! = "Image/jpeg" & $ f ["type"]! = "Image/x-png") {echo "<script> alert ('only images can be uploaded '); window. close () </script> "; return false;} // obtain the file extension $ temp_arr = explode (". ", $ f [" name "]); $ file_ext = array_pop ($ temp_arr); $ file_ext = trim ($ file_ext); $ file_ext = strtolower ($ file_ext ); // new file name $ new_file_name = md5 (date ("YmdHis ")). '. '. $ file_ext; echo $ dest = $ uppaths. $ filename. "/". date ("ymdhis "). "_". $ new_file_name; // set the file name to the date plus the file name to avoid repeated upload directory e Cho $ dest1 = $ uppath. $ filename. "/". date ("ymdhis "). "_". $ new_file_name; // set the file name to the date plus the file name to avoid duplication. $ r = move_uploaded_file ($ f ['tmp _ name'], $ dest);?>
