PHP: return value of user selected array -


please excuse if duplicate or similar post, have searched on here , not figure out answer question based on previous posts...

i know may noob question (im trying desperately teach myself php please bear me!)

i have custom concrete5 block building (using jordanlev's awesome designer content).

here code: 

<?php  if ($field_3_select_value == 1): ?> <!-- enter markup here field "heading placement left or right?" : choice "head-left" -->  <?php  endif; ?>  <?php  if ($field_3_select_value == 2): ?> <!-- enter markup here field "heading placement left or right?" : choice "head-right" --> <?php  endif; ?>  <?php  if ($field_4_select_value == 1): ?> <!-- enter markup here field "heading placement - top middle bottom" : choice "top" --> <?php  endif; ?>  <?php  if ($field_4_select_value == 2): ?> <!-- enter markup here field "heading placement - top middle bottom" : choice "middle" --> <?php  endif; ?>  <?php  if ($field_4_select_value == 3): ?> <!-- enter markup here field "heading placement - top middle bottom" : choice "bottom" --> <?php  endif; ?>  <div class="span 7 head <?php echo $field_3_select_value->$value; ?> <?php echo $field_4_select_value->$value; ?>">  <?php  if (!empty($field_6_textbox_text)): ?> <h2><?php  echo htmlentities($field_6_textbox_text, ent_quotes, app_charset); ?></h2> <?php  endif; ?>  <?php  if (!empty($field_7_textbox_text)): ?> <h2><?php  echo htmlentities($field_7_textbox_text, ent_quotes, app_charset); ?></h2> <?php  endif; ?>  <?php  if (!empty($field_8_textbox_text)): ?>     <h2><?php  echo htmlentities($field_8_textbox_text, ent_quotes, app_charset); ?></h2> <?php  endif; ?>

what im trying achieve value of $field_3_select_value & $field_4_select_value appear content of array in class of div.

next have 3 text boxes inserted (if filled in user) styled according classes on div above.

is possible? need build 'foreach' loop , if so, can point me in right direction? prefer learn how rather me, , direction , of course constructive criticism appreciated!

thanks in advance :)

you can use switch:

<?php     switch ($field_3_select_value):         case 1: $class3 = 'head-left'; break;         case 2: $class3 = 'head-right'; break;         default: $class3 = '';     endswitch;      switch ($field_4_select_value):         case 1: $class4 = 'top'; break;         case 2: $class4 = 'middle'; break;         case 3: $class4 = 'bottom'; break;         default: $class4 = '';     endswitch; ?> <div class="span 7 head <?php echo $class3; ?> <?php echo $class4; ?>">

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...
