php - Select after insert doesn't return the inserted row -


background information: work on application (professional, not personal) manage files. ui web based , low-level file managing functions java based.

each file , directory referred 'node' in app , has row in table store inode, name, parent id, etc...

the problem: when action adding node or renaming example, java function called update database in relation real file system.

i have problem when copy node (everything works when add, rename, delete, ... node if same exact java function called copy) ==> file copied, java function called (in case sql insert of new file infos) , select in php node id of copied file.

just after insert can see row in phpmyadmin select in php doesn't return it.

what i've tried: it's not timing (i've put 20 seconds sleep test , have time see row in pma) , caches disabled in codeigniter (and i've put various dumps in codeigniter code confirm). tried pdo driver of codeigniter , result same. , i've tried delete of conditions in clause (and clause altogether too) , again, same result.

the thing works open new connection db , redo query in code below:

public function getidfornode($name, $parentid) {     $id = 0;     $name = self::cleanname($name);     $parentid = intval($parentid);     if (empty($name)) {         log::error("\$name can't empty.");     } else if ($parentid < 0) {         log::error("\$parentid can't < 0.");     } else {         $db = appdatabase::getinstance();         $sql = "select node_id                 nodes                 inode_id > 0                     , parentnode_id = ?                     , record_label = binary ?                     , record_deleted null";         $result = $db->query($sql, [$parentid, $name])->row_array();         ///////////////////////////////////////////////////////////////////         if (empty($result)) {             $db2 = new mysqli(db_host, db_user, db_pass, db_name);             $result2 = $db2->query("                 select node_id                 nodes                 inode_id > 0                     , parentnode_id = ".$parentid."                     , record_label = binary '".$db2->escape_string($name)."'                     , record_deleted null             ");             $result = $result2->fetch_assoc();             $result2->free();             $db2->close();         }         ///////////////////////////////////////////////////////////////////         $id = (!empty($result) && !empty($result['node_id'])) ? intval($result['node_id']) : 0;     }     return $id; }

vue.js - Create hooks for automated testing -

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...
