php - post rating for an individual item in a list using codeigniter -

-

i’m having heck of time figuring out how post rating individual item in list of items,

this code let’s me rate multiple items, not single items:

for($i=0;$i<2;$i++){     $doc_item_id = $_post['item_id0'][$i];     $doc_rating  = $_post['document_rating'][$i];      $it_rt = array(         'item_id' => $doc_item_id,         'rating'  => $doc_rating,     );       $this->purchases_model->update_document($it_rt); }

whereas code let’s me rate first item (or last item depending on put "break;"):

foreach($_post['item_id0'] $doc_item_id){       foreach($_post['document_rating'] $doc_rating){     }     break; } $it_rt = array(       'item_id' => $doc_item_id,     'rating'  => $doc_rating, ); $this->purchases_model->update_document($it_rt);

any thoughts on how correct either of these such user rate individual item of choosing appreciated,

if user supposed choose item rate (instead of rating items @ same time), should allow him (showing 1 item, let him select 1 using radio buttons...), , should able, php side, retrieve index of item modify.

finally, in order modify 1 item, code should (php side, have update html form well)

$i = $_post['item_index']; // here i'm supposing have added radio buttons                            // named 'item_index' allow user choose item rate  $doc_item_id = $_post['item_id0'][$i]; $doc_rating = $_post['document_rating'][$i] ;  $it_rt = array(         'item_id'=> $doc_item_id,       'rating' => $doc_rating,       );  $this->purchases_model->update_document($it_rt);

in fact original code without for loop.

php - What is the difference between $_SERVER['PATH_INFO'] and $_SERVER['ORIG_PATH_INFO']? -

-
what’s difference between $_server['path_info'] , $_server['orig_path_info'] ? how use them? when run print_r($_server) , path_info , orig_path_info not present in array. why not? how can enable them? i have read php manual on them, still don’t understand them. the path_info variable present if invoke php script this: http://www.example.com/phpinfo.php/hello_there it's /hello_there part after .php script. if don't invoke url that, there won't $_server["path_info"] environment variable. the porig_ prefix uncommon. path_info standard cgi-environment variable, , should never prefixed. did read that? (there issues around php3/php4 if invoked php interpreter via cgi-bin/ - hardly has such setups today.) for reference: http://www.ietf.org/rfc/rfc3875

i'm attempting recode old c++ program in fortran make use of lapack (i'm aware c++ have lapack++, i'm having lot of trouble installing it, gave up). i didn't have problems compilation, when had variables declared real . when started coding section of program required lapack, found parameters passed dsyev need double precision . tried change double precision (including changing hard coded numbers double precision counterparts, i.e. 0.0 -> 0.0d0) when try compile, following error of functions , subroutines i've written: error: return type mismatch of function <function> @ (1) (real(4)/real(8)) i'm not sure coming from, in program has been changed double precision. for example, i've declared following: double precision :: alpha(3),d(3),zeta1,zeta2 double precision :: a1(3),a2(3),d1(3),d2(3) double precision :: pi pi = 3.14159265359d0 alpha = (/0.109818d0, 0.405771d0, 2.22766d0/) d = (/0.444635d0, 0.535328d0, 0.154329d0 /) 10 i=1,3 ...

queue - mq_receive: message too long -

-
i implementing communication between 2 processes using queue. problem when call function mq_receive, error: message long. i have done following: struct mq_attr attr; long size = attr.mq_msgsize; .... // initializing queue "/gateway" int rc = mq_receive(gateway, buffer, size, &prio); if print size value, size=1, while when print same size program (got same mechanism), not long integer ( -1217186280 )... how can solve error?....so while size = 1, believe it's right "message long" why 1? p.s. have tried put : int rc = mq_receive(gateway, buffer, sizeof(buffer), &prio); but no result. it seems need read docs more carefully. when call mq_receive should pass size of destination buffer. this size must greater mq_msgsize attribute of queue . in addition, seems have error in queue attributes initialisation makes proper mq_receive call impossible. here standard message queue session: fill mq_attr struct ( doc ): struct mq_a...
