php - MySQLi Connection Issue -


i having trouble getting mysqli connect , respond properly. should relaying connection error time unable connect database, doesn't, when enter invalid details in attempt force connection error.

$emailaddress = $_post['emailaddress']; $password = $_post['password']; if ($emailaddress&&$password)     {         $db = new mysqli('loalhost','rot','','fitesshouse');         if($db->connect_errno > 0)           {             die('unable connect database [' . $db->connect_error . ']');         }     }

edit: let me more clear. trying mysqli return connection error because connection fails. i'm not trying fix connection. when hit "submit" takes me blank page, means die statement not working.

fixed , have error:

notice: undefined index: emailaddress in /applications/xampp/xamppfiles/htdocs/fitnesshouse/login.php on line 5

this line of code should display error , stop script:

$db = new mysqli('loalhost','rot','','fitesshouse')     or die('unable connect database [' . $db->connect_error . ']');

you can use trigger_error instead of die:

$db = new mysqli('loalhost','rot','','fitesshouse'); if($db->connect_errno)     trigger_error('unable connect database [' . $db->connect_error . ']', e_user_error);

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...
