Storing the last input text whilst using the POST method with PHP -


the idea:

i have been trying create one-way chat system based on predictions user, using pre-set automatic responses through server side.

the problem:

what have far works great, although problem have can't store last user inputted message locally chat flow in messages without using lots of _get's.

with current code:

if (isset($_post['test'])) {     $test = htmlentities($_post['test']);     echo "<span class='you'>".$name."</span>: ".$test;     if (preg_match('~\b(?:about)\b~', $test)) {         echo '<br />'.$about;     } else if (preg_match('~\b(?:projects?|works?)\b~i', $test)) {         echo '<br />'.$projects;     } else if (preg_match('~\b(?:contact|email|inquiry)\b~', $test)) {         echo '<br />'.$contact;     } else {         echo "<br />error!";     } }

for example, if user types projects input, $projects echo's correctly, after if user types about, $about show, previous projects message disappears.

what have tried:

  • i've tried put each if in own isset.
  • thought loop makes new input after every message, although believe not efficient use of php, need find more minimal way.

you use ajax old messages won't disappear on submit.

have <ul> chat messages. when user posts, create <li> message , 1 answer, , keep adding them...

go - Idiomatic way to handle template errors in golang -

say have html/template following: <html> <body> <p>{{somefunc .somedata}}</p> </body> and somefunc returns error. there idiomatic way deal this? if write directly responsewriter , status code 200 has been written before encounter error. var tmpl *template.template func handler(w http.responsewriter, r *http.request) { err := tmpl.execute(w, data) // "<html><body><p>" has been written... // err? } preferably return status code 400 or such, can't see way if use template.execute directly on responsewriter . there i'm missing? since template engine generates output on-the-fly, parts of template preceding somefunc call sent output. , if output not buffered, (along http 200 status) may sent. you can't that. what can perform check before call template.execute() . in trivial case should enough call somefunc() , check return value. if choose path , return value of somefunc() c...
