php - Doctrine QueryBuilder Re-Use Parts -


i want count fields fits conditions , them page page doctrine query builder.

i'm generating query depends filter fields.

first section counting records can calculate pages.

$qb = $em->createquerybuilder();  $qb     ->select('count(m.id)')     ->from('csmediabundle:mediaitem', 'm')     ->where(         $qb->expr()->eq('m.media', $media->getid())     );  $filters = $request->request->get('filter');  if(!empty($filters['size'])) {     foreach($filters['size'] $key => $value) {         if(!empty($value)) {             $qb->andwhere(                 $qb->expr()->eq('m.'.$key, ':'.$key)             )->setparameter($key, $value);         }     } }  if(!empty($filters['sliders'])) {      $qb         ->leftjoin('cssliderbundle:slideritem', 's', 'on', 'm.id = s.media_id')         ->andwhere(             $qb->expr()->in('s.sliders', $filters['sliders'])         ); }  $media_count = $qb->getquery()->getsinglescalarresult();

second section getting records calculated page using same filters, changing select , final parts (getsinglescalarresult getresult)

i wonder if there way change select , result parts not use filters again , again...

yeah, that's functions for:

function filter($qb, $filters) {     if (!empty($filters['size'])) {         foreach($filters['size'] $key => $value) {             if (!empty($value)) {                 $qb->andwhere(                     $qb->expr()->eq('m.'.$key, ':'.$key)                 )->setparameter($key, $value);             }         }     }      if (!empty($filters['sliders'])) {         $qb             ->leftjoin('cssliderbundle:slideritem', 's', 'on', 'm.id = s.media_id')             ->andwhere(                 $qb->expr()->in('s.sliders', $filters['sliders'])             );     }      return $qb; }  $filters = $request->request->get('filter');  // count $qb = $em->createquerybuilder(); $qb     ->select('count(m.id)')     ->from('csmediabundle:mediaitem', 'm')     ->where(         $qb->expr()->eq('m.media', $media->getid())     );  $media_count = filter($qb, $filters)->getquery()->getsinglescalarresult();  // entities $qb = $em->createquerybuilder(); $qb     ->select('m')     ->from('csmediabundle:mediaitem', 'm')     ->where(         $qb->expr()->eq('m.media', $media->getid())     );  $media_entities = filter($qb, $filters)->getquery()->getresult();

another way clone query builder object:

$qb = $em->createquerybuilder(); $qb->from('csmediabundle:mediaitem', 'm')     ->where(         $qb->expr()->eq('m.media', $media->getid())     );  $filters = $request->request->get('filter'); if (!empty($filters['size'])) {     foreach($filters['size'] $key => $value) {         if (!empty($value)) {             $qb->andwhere(                 $qb->expr()->eq('m.'.$key, ':'.$key)             )->setparameter($key, $value);         }     } }  if (!empty($filters['sliders'])) {     $qb         ->leftjoin('cssliderbundle:slideritem', 's', 'on', 'm.id = s.media_id')         ->andwhere(             $qb->expr()->in('s.sliders', $filters['sliders'])         ); }  $qb2 = clone $qb;  $qb->select('count(m.id)') $media_count = $qb->getquery()->getsinglescalarresult();  $qb2->select('m') $media_entities = $qb2->getquery()->getresult();

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod...
