after 1 click : enter image description here

after 2sd click on same item: enter image description here

here code

model

public function get_categories($parent_id) {     return $this->db->select('id,parent_id,category_title_fr,category_title_ar,categorie_trie')                     ->from($this->table_categories)                     ->where('parent_id', $parent_id)                     ->order_by('parent_id')                     ->get()                     ->result(); }  public function get_categorieschild() {     return $this->db->select('id,parent_id,category_title_fr,category_title_ar,categorie_trie')                     ->from($this->table_categories)                     ->where('parent_id','0')                     ->get()                     ->result(); }

controller

    $data['cat_niveau1'] = $this->listeprogram->get_categorieschild();     $this->load->view('templates/ar/template', $data);

view

foreach ($cat_niveau0 $cat0) {     echo '<li><a href="'.base_url().'index.php/program/programme_chaine_ar/'.$cat0->id.             '" class="menu-button menu-drop"><span class="menu-label">'.$cat0->category_title_ar.'</span></a>';     echo '<div class="menu-dropdown menu-dropdown1"><ul class="menu-sub">';     foreach ($cat_niveau1 $cat1) {         if ($cat0->id == $cat1->parent_id) {             echo '<li><a href="'.base_url().'index.php/program/programme_chaine_ar/'.$cat0->id.'/'.$cat1->id.                     '" class="menu-subbutton"><span class="menu-label">'.$cat1->category_title_ar.'</span></a></li>';         }     }     ?>     <?php         echo '</ul></div></li>'; }

first, don't see passing cat_niveau0. then, should either create data both levels in controllers , pass multidimentional associative array, or pass cat_niveau0, in view 

foreach ($cat_niveau0 $cat0) { # $cat1 = # array through model based on cat0  }

note: have strange names models: 1 get_categories should get_categorieschild , viceversa, maybe your're getting little mixed which :)

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...
