javascript - Ajax send FormData and retrieve multidimensional array -


alright have form select csv file , when hit sales_importer button java call php function , returned multidimensional array later processing. when run following code alert box multidimensional array of values seems in string form. when alert(result[0][0]); [ in alert box.

i have tried changing datatype in ajax call json fails still 200 response browser. suggestions of might going on/how go fixing it?

js

$('body').on('click', '#sales_importer', function() {     $.ajax({         type: 'post',         data: new formdata($('form[id="import_form"]')[0]),         cache: false,         contenttype: false,         processdata: false,          url: admin_url+'clients/import',         success: function(result){                 alert(result);                               }     });  });

php

public function import() {     if ($this->input->is_ajax_request()) {         if (isset($_files['client_file_csv']['name']) && $_files['client_file_csv']['name'] != '') {                         // temp file path             $tmpfilepath = $_files['client_file_csv']['tmp_name'];             // make sure have filepath             if (!empty($tmpfilepath) && $tmpfilepath != '') {                  // setup our new file path                 $newfilepath = temp_folder . $_files['client_file_csv']['name'];                  if (!file_exists(temp_folder)) {                     mkdir(temp_folder, 777);                 }                 if (move_uploaded_file($tmpfilepath, $newfilepath)) {                      $import_result = true;                     $fd            = fopen($newfilepath, 'r');                     $rows          = array();                     while ($row = fgetcsv($fd)) {                         $rows[] = $row;                     }                     $data['total_rows_post'] = count($rows);                     fclose($fd);                                                 echo json_encode($rows);                  }                 unlink($newfilepath);             }         }     } }

if want able use data in javascript, you're going need apply key. in php:

echo json_encode( array('rows' => $rows) );

this allows access rows in jquery ajax success function:

success: function(result){         // rows available result.rows     if( result.rows ){         // result.rows...         console.log( result.rows );         $.each( result.rows, function(i, arr){              console.log( arr );         });     }                      }

remember result.rows going javascript object, you'll need use jquery's each loop through rows , want do. use console view result.rows, , you'll see mean.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

python Tkinter Capturing keyboard events save as one single string -

is possible store keyboard events 1 string? code below stores 1 char , prints it. card reader or bar code reader, contains collection of character/ string not 1 character @ time. goal save char pressed text variable. from tkinter import * root = tk() def key(event): text= event.char text+= event.char print ("pressed", text) def callback(event): frame.focus_set() print ("clicked at", event.x, event.y) frame = frame(root, width=100, height=100) frame.bind("<key>", key) frame.bind("<button-1>", callback) frame.pack() root.mainloop() currently, creating text variable , everytime key() function gets called, , text stores last character typed. you can define text module level variable , , use module level text inside key function - text = '' def key(event): global text text+= event.char print("pressed", text)

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
