is correct code htaccess setting header noindex nofollow rewritecond %{query_string} (^|&)cart? [nc] rewriterule .* - [e=my_set_header:1] header set x-robots-tag "noindex, nofollow" env=my_set_header so following url cannot indexed search engines. http://www.mysite.com/cart?qty=1&id_product=8&token=7775324f4cd8c884155af53ca90e44ad&add actually moz analytics crawling these types of url in <a href="http://www.mysite.com/cart?qty=1&id_product=8&token=7775324f4cd8c884155af53ca90e44ad&add">add cart</a> as duplicate page content. dont know why these url add cart url , these nothing content. also need suggestion online tutorial on playing htaccess . thanks. /cart isn't query_string request uri. can use rule instead: rewritecond %{query_string} .+ rewriterule ^cart/?$ - [e=my_set_header:1]

i have given date: 2013-12-20 this issue date of product product expiries in 6 months date of issue. expiration date not stored want check given issue date if expiring in next month of now(). so guess add 6 months issue date , check + interval of 1 month if expiring? here tried: select * `products` date_add(`issue_date`,interval 6 month) < date(now() + interval 1 month) order `issue_date` asc what i'm doing wrong? select * products now() <= date_add(issue_date, interval 7 month) && now() >= date_add(issue_date, interval 6 month) order issue_date asc; the first item has returned has due date today (so issue date + 6 months = today); than due date tomorrow (so issue date + 6 months + 1 day = today); ... than due date 1 month today(so issue date + 6 months + 1 month = issue date + 7 months = today)

i know following undefined because trying read , write value of variable in same expression, is int a=5; a=a++; but if why following code snippet not undefined int a=5; a=a+1; as here trying modify value of a , write @ same time. also explain why standard not curing or removing undefined behavior , in spite of fact know undefined? long story short, can find every defined behavior in standard. not mentioned there defined - undefined. intuitive explanation example: a=a++; you want modify variable a 2 times in single statement. 1) a= //first time 2) a++ //second time if here: a=a+1; you modify variable once: a= // (a+1) - doesn't change value of why don't standard define a=a++ behavior? one of possible reasons is: compiler can perform optimizations. more cases define in standard, less freedom compiler has optimize code. because different architectures can have different increasing instructions implementations, compiler wouldn't use...

i need value of array in model compare value.how can it? code in model: function get_order(){ $this->db->select('order'); $this->db->order_by('order','desc'); $this->db->limit(1); $query=$this->db->get('section'); i need last order record $query.i tried code not show . echo $query['order']; thanks help try this, function get_order() { $result = $this->db->select('order'); ->order_by('order','desc'); ->limit(1) ->get('section') ->row(); return $result->order; } this function return order . hope helps :)

in request_irq() register interrupt handlers, why use flag irqf_sample_random , entropy pool? the entropy pool collects randomness /dev/random , /dev/urandom devices. in outdated kernels, have used irqf_sample_random tell kernel times @ device generates interrupts unpredictable. since kernel version 3.6, kernel handles interrupt randomness automatically, , flag no longer exists.
