php - Succes messages after form posts on another page -

-

i making succes-message-page when user created.

in matter curious security. if make page @

domain.com/register/success

is there security matters, should aware of? problem is, want following:

/register = form

/register/perform = form has been posted, if error show error messages, if succes redirect

/register/success = page succes message.

but in setup able access /register/success, because can't check if form has been posted or that.

the reason want because want track each visit /register/success goal in google analytics.

is there way can achieve not possible success-message shown if you've not been trying create user?

my own solutions

1) ajax call - if succes javascript-redirect /register/success

2) php header() /register/success if no error on /register/perform

but doesn't fit problem user not being able access page if has not been trying create user.

thanks in advance!

if understand question use sessions flag messages errors warning , notices. snippet error reporting system:

if(!empty($_session['error'])) {  echo<<<message <div id="wrapper_div">     <div id="messagepane">     <span id="message" class="messageflash error">{$_session['error']}     <a href="#close" class="close" onclick="hide('messagepane')">×</a></span>     </div> </div> message;  unset($_session['error']);

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.

erlang - Saving a digraph to mnesia is hindered because of its side-effects -

-
updated the digraph library in erlang implements data type side-effectful. each operation on data type saves new state in ets table -- instead of returning altered version of itself, more common in functional languages. the problem usage perspective, impedes effort store or pass around state in convenient way requiring me first "collect" state before can start juggle around. the closest solution have seen far serializer/deserializer , these have drawback tied current structure of digraphs instead of operating on abstract type -- prevents future proof solution. update pascal pointed out serializer utilizes interface of digraph, , hence eliminates drawback mentioned above. better, albeit still inconvenient, see no better alternative. what recommendation on how store digraphs? should go different data type altogether? thanks. i not sure understand concern. fact digraph stored in ets transparent in user interface, might want chnge either exchange digr...
