php - Catchable fatal error: Object of class mysqli_result could not be converted to string in registration -


i have created registration form , using following code in order display loginid created when form completed. following code results in "catchable fatal error: object of class mysqli_result not converted string in". i'm not sure why doing this.

$result = mysqli_query($con, "select loginid user name='$namefromform' , password='$pwd'");  echo $result;

i have tried using

$sql = mysqli_query($con, "select loginid user name='$namefromform' , password='$pwd' '$login'"); $result = mysqli_query($con, $sql); echo $result->fetch_object()->$login;

to fix problem suggested in regards above error although results in errors "warning: mysqli_query() [function.mysqli-query]: empty query in"

and

"fatal error: call member function fetch_object() on non-object in "

in regards 2 new lines. i'm not sure i'm going wrong this, data trying recieve auto increment primary key if has impact. i'm not concerned security of doesn't need secure, work.

thanks

try this, 

 $result = mysqli_query($con, "select loginid login user name='$namefromform' , password='$pwd'");      $row = mysqli_fetch_array($result);     echo $row['login'];

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

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
