i am sorry that i confuse you.My question is;1) does the .undefined is like the prebuild object's property? for example, the .length property of String of object.2) .initDone: what does it means ? 3) what the following code does?var BBCode = function(){ window.undefined = window.undefined; this.initDone = false; } 4) what the following code does? and what does the ._target means?BBCode.prototype.init = function(t){ if(this.initDone)return false; if(t == undefined)return false; this._target = t? document.getElementById(t) : t; this.initDone = true; return true; } 5) what does the following code do?BBCode.prototype.noForm = function(){ return this._target == undefined; }

Could you annalysis the reason to me?And also if you are free, could you help me to solve the refresh problem by useing the session varible to pass the cid value, i am keen to know how to do that. Thanks.

I am almost there now, haha. i added the redirect code to the end of edit3.php as following, they work. <?echo"<meta http-equiv='Refresh' content='1; URL=index.php'>";?> or <?phpecho "<meta http-equiv=\"refresh\" content=\"1;URL=http://www.businessfind101.com/\">";?> But the problem for me, it work in funny way.after i edit the form from edit2.php, and then it gos to the edit3.php, the funny thing is here, it automatically go back to the index.php by itself. that is not good way to back, i need it back to index.php when i press the back from the top button of bar.and also i find another strange thing as well. After i redirect back to index.php from the edit3.php by automatically (althoght i don't like it), i will find another refersh problem as well when i click on the back from the index.php.and the masage as following;Warning: Page has Expired The page you requested was created using information you submitted in a form. This page is no longer available. As a security precaution, Internet Explorer does not automatically resubmit your information for you. To resubmit your information and view this Web page, click the Refresh button. and the top of the address bar has : http://www.businessfind101.com/edit2.phpCould you tell me how solve these problem?

Hi justsomeguy;You are right, there is not value in the edit2.php after i redict back to edit2.php from edit3.php. Becaue the value get from edit.php, but now i don't excute the edit.php to let it pass value to edit2.php. This is why i has the refresh problem. Thanks a lot, you give me a very good analysis, i understand it now.What i am doing for the code? I want to let the user update their data by themself, and save it back to database. and i do that by the following step as what you said from last thread.1) ask the user name by a formbut here, i will pass the user cid to eddit2.php by attached the cid value to a textbox as well, for later use.2) base on the user name, i will select the user data out of database, then diplay on a screen to let the user edit their detail, after finish that, i will save the update data to database.and also i will receied the cid value which it is from edit.ph, and put it into the session varible for edit3.php use.3) in the edit3.php, according the cid value which from edit.pho, and processing it from edit2.php, i will update the user's data. then redirect back to previous page.The above is all i want to do.But you are right, that doesn't make sence to redirect back to edit2.php, because it is just a submit form, nothing else.so i will redirect to another page.but after i added the redirect code on, it give me some massage as following;Warning: Cannot modify header information - headers already sent by (output started at /home/biznisfi/public_html/edit3.php:6) in /home/biznisfi/public_html/edit3.php on line 43the code i added as following; this is edit3.php<?session_start();?><? $con = mysql_connect("localhost", "biznisfi_xbl","1968rich");if (! $con){die('Could not connect: ' . mysql_error());} mysql_select_db("biznisfi_xbl", $con);if(isset($_SESSION['Cid']))$cid=$_SESSION['Cid'];$arrtopic = $_REQUEST['topic'];if(is_array($arrtopic)){foreach($arrtopic as $value) $sql = "update Customer2 set Topic='$value' where Cid= '$cid'";mysql_query($sql);}$arrdes=$_POST['des'];if(is_array($arrdes)){foreach($arrdes as $value)$sql = "update Customer2 set Des='$value' where Cid='$cid'";mysql_query($sql);}unset($_SESSION['Cid']);?><?phpheader("Location: index.php");?> even i change the redirtect to www.ebay.com, it does not help. Could you tell what's problem here, Thanksand the index.php like the following, it just use to link to the edit.php, etc, nothing else, not value problem in here. <html><head><style type="text/css"></style></head><body> <center> <a href='tologin.php'>login</a> <a href='index.php'> Search </a> <a href='submit.php'>submit your words</a> <a href='eUserName.php'>Delete your words</a> <a href='eUserE.php'> Edit your words </a> <a href='oTopic.php'> OverView Topic </a> </center> <center> <form name="input" class="id1" action="st1.php" method="get"> Search: <input type="text" name="SText"> <input type="submit" value="Submit"> </form> </center></body></html>
