I have to round up all the prices of Opencart. I used the method round() on function calculate () in system / library and it works well.
The problem is in the total that is not based on the prices rounded, but on the real ones. How can I fix this?
This is my code in tax.php:
public function calculate($value, $tax_class_id, $calculate = true) {
if ($tax_class_id && $calculate) {
$amount = $this->getTax($value, $tax_class_id);
return round($value + $amount);
}else{
return round($value);
}
}

Can we reduce the time for TrivialDurationThresholdMilliseconds using miniprofiler tool as this code is not showing any effects written inside global.asax.cs
private void StartProfiler()
{
MiniProfiler.Start();
MiniProfiler.Settings.TrivialDurationThresholdMilliseconds = 0.01M;
}
and calling StartProfiler() method inside Application_BeginRequest
As Burkay mentioned in his comment, the TrivialDurationThresholdMilliseconds setting does not appear to be used; so requests of less than 20ms should be recorded and displayed.
If you want to limit only record requests within a range of times you could implement something like this (typically in the Application_EndRequest method of the global.asax.cs)
if (MiniProfiler.Current != null)
{
decimal minimumMillisecondsToRecord = 0.1m;
decimal maximumMillisecondsToRecord = 5.1m;
var durationOfProfiling = DateTime.Now.ToUniversalTime() - MiniProfiler.Current.Started;
if (durationOfProfiling.Milliseconds >= minimumMillisecondsToRecord
&& durationOfProfiling.Milliseconds <= maximumMillisecondsToRecord)
{
MiniProfiler.Stop(discardResults: false);
}
else
{
MiniProfiler.Stop(discardResults: true);
}
}
A simple version of my document document is the following structure:
doc:
{
"date": "2014-04-16T17:13:00",
"key": "de5cefc56ff51c33351459b88d42ca9f828445c0",
}
I would like to group my document by key, to get the latest date and the number of documents for each key, something like
{ "Last": "2014-04-16T16:00:00", "Count": 10 }
My idea is to to do a map/reduce view and query setting group to true.
This is what I have so far tried. I get the exact count, but not the correct dates.
map
function (doc, meta) {
if(doc.type =="doc")
emit(doc.key, doc.date);
}
reduce
function(key, values, rereduce) {
var result = {
Last: 0,
Count: 0
};
if (rereduce) {
for (var i = 0; i < values.length; i++) {
result.Count += values[i].Count;
result.Last = values[i].Last;
}
} else {
result.Count = values.length;
result.Last = values[0]
}
return result;
}
You're not comparing dates... Couchbase sorts values by key. In your situation it will not sort it by date, so you should do it manually in your reduce function. Probably it will look like:
result.Last = values[i].Last > result.Last ? values[i].Last : result.Last;
and in reduce function it also can be an array, so I don't think that your reduce function always be correct.
Here is an example of my reduce function that filter documents and leave just one that have the newest date. May be it will be helpful or you can try to use it (seems it looks like reduce function that you want, you just need to add count somewhere).
function(k,v,r){
if (r){
if (v.length > 1){
var m = v[0].Date;
var mid = 0;
for (var i=1;i<v.length;i++){
if (v[i].Date > m){
m = v[i].Date;
mid = i;
}
}
return v[mid];
}
else {
return v[0] || v;
}
}
if (v.length > 1){
var m = v[0].Date;
var mid = 0;
for (var i=1;i<v.length;i++){
if (v[i].Date > m){
m = v[i].Date;
mid = i;
}
}
return v[mid];
}
else {
return v[0] || v;
}
}
UPD: Here is an example of what that reduce do:
Input date (values) for that function will look like (I've used just numbers instead of text date to make it shorter):
[{Date:1},{Date:3},{Date:8},{Date:2},{Date:4},{Date:7},{Date:5}]
On the first step rereduce will be false, so we need to find the biggest date in array, and it will return
Object {Date: 8}.
Note, that this function can be called one time, but it can be called on several servers in cluster or on several branches of b-tree inside one couchbase instance.
Then on next step (if there were several machines in cluster or "branches") rereduce will be called and rereduce var will be set to true
Incoming data will be:
[{Date:8},{Date:10},{Date:3}], where {Date:8} came from reduce from one server(or branch), and other dates came from another server(or branch).
So we need to do exactly the same on that new values to find the biggest one.
Answering your question from comments: I don't remember why I used same code for reduce and rereduce, because it was long time ago (when couchbase 2.0 was in dev preview). May be couchbase had some bugs or I just tried to understand how rereduce works. But I remember that without that if (r) {..} it not worked at that time.
You can try to place return v; code in different parts of my or your reduce function to see what it returns on each reduce phase. It's better to try once by yourself to understand what actually happens there.
I forget to mention that I have many documents for the same key. In fact for each key I can have many documents( message here):
{
"date": "2014-04-16T17:13:00",
"key": "de5cefc56ff51c33351459b88d42ca9f828445c0",
"message": "message1",
}
{
"date": "2014-04-16T15:22:00",
"key": "de5cefc56ff51c33351459b88d42ca9f828445c0",
"message": "message2",
}
Another way to deal with the problem is to do it in the map function:
function (doc, meta) {
var count = 0;
var last =''
if(doc.type =="doc"){
for (k in doc.message){
count += 1;
last = doc.date> last?doc.date:last;
}
emit(doc.key,{'Count':count,'Last': last});
}
}
I found this simpler and it do the job in my case.
This thread was useful in finding out the next run-time for a scheduled task.
How do I find out the next run time for a Scheduled Task?
But, is there also a way to simply get the next scheduled task due to run?
If I can get the date and name of the next task due to run, I can plug that date into a jQuery countdown timer, which will display a countdown to the next scheduled task, something like:
TaskABC due to run in:
12 03 20
hrs min sec
. This is for an admin interface in case you're wondering how geeky can people get:-)
EDIT
I had the same thought as Bill. But was curious if there was another way.
I poked around and apparently the internal Scheduler class maintains a list of upcoming tasks. The list is private, but you can use the same reflection technique to access it. Interestingly the list also includes system tasks like the mail spooler, session/application trackers, watchers, etecetera. So you must iterate through it until you find a "scheduled task" ie CronTabEntry
Below is a very lightly tested function that seems to do the trick in CF9. (Note, includes the CreateTimeStruct function from http://www.cflib.org).
Rules:
Returns a structure containing the name and time remaining until the next task. If no tasks were found, result.task is an empty string.
Excludes paused tasks
Usage:
result = new TaskUtil().getNextTask();
WriteDump(result);
CFC
component {
public struct function getNextTask() {
// get list of upcoming tasks from factory (UNDOCUMENTED)
local.scheduler = createObject("java", "coldfusion.server.ServiceFactory").getSchedulerService();
local.taskField = local.scheduler.getClass().getDeclaredField("_tasks");
local.taskField.setAccessible( true );
local.taskList = local.taskField.get(local.scheduler);
// taskList contains system jobs too, so we must iterate
// through the tasks to find the next "scheduled task"
local.nextTask = "";
local.tasks = local.taskList.iterator();
while ( local.tasks.hasNext() ) {
local.currTask = local.tasks.next();
local.className = local.currTask.getRunnable().getClass().name;
// exit as soon as we find a scheduled task that is NOT paused
if (local.className eq "coldfusion.scheduling.CronTabEntry"
&& !local.currTask.getRunnable().paused) {
local.nextTask = local.currTask;
break;
}
}
// if we found a task, calculate how many days, hours, etcetera
// until its next run time
local.details = { task="", remaining={} };
if ( isObject(local.nextTask) ) {
local.secondsToGo = (local.nextTask.getWhen() - now().getTime()) / 1000;
local.details.task = local.nextTask.getRunnable().task;
local.details.remaining = createTimeStruct(local.secondsToGo);
local.details.nextDate = dateAdd("s", local.nextTask.getWhen() / 1000
, "January 1 1970 00:00:00" );
}
return local.details;
}

My first thought is to iterate Leigh's getNextRunTime(string taskName) function over the collection of tasks. You can get an array of structs containing the details of all scheduled tasks using taskArray = createobject("java","coldfusion.server.ServiceFactory").getCronService().listAll();
The key in the struct containing the task name is "task". So you can extract all the task names as an array for example, run Leigh's function on each element and determine which one will run next.
I am not able to properly launch my site at http://www.enbloc.sg
This is because my programmer is not able to figure out a problem. Any help would be much appreciated.
Visitors vote by clicking on one colour on the traffic light. They are supposed to only have one vote.
The site first checks for cookies and then ip address of voter. If the 2 are identical to a previous visitor, then voting is not allowed. If only one of the 2 are repeated, then voting is permitted.
The idea of having a double restriction is to allow different voters behind a fixed IP to vote. E.g. the employees of a company would not be able to vote since they are likely to be accessing the site via a fixed IP address.
However, currently, visitors are able to click on ALL 3 colours to register 3 votes on their first visit to the site. My coder is not able to resolve this issue and has abandoned me.
I would be most grateful if someone can help. I believe the relevant codes are appended below.
Apologies if my posting is wrongly formatted.
Thanks very much,

}
These changes will help:
var already_voted = false;
function vote_update(ip_address, issue_num, vote_status)
{
if(alread_voted) return;
already_voted = true;
// rest of the code
}
This will make sure that only one vote can be cast during a single visit. The cookies take care of the rest and are already working fine.
I need to replicate the Google Analytics date picker (plus a few new options). Can anyone tell me how to highlight all the cells on a calendar between two dates. My basic JavaScript is OK but I think I'm getting a bit out of my depth.
I'm using JQuery 1.5.1 and JQuery UI 1.8.14.
In needed to replicate Google Analytics date picker as well. I know you were asking just about highlighting cells, but if someone else would prefer complete solution, you can see my answer from another question: jquery google analytics datepicker
Here's a solution using the built-in 'onSelect' event (jsFiddle):
$(document).ready(function() {
'use strict';
var range = {
'start': null,
'stop': null
};
$('#picker').datepicker({
'onSelect': function(dateText, inst) {
var d, ds, i, sel, $this = $(this);
if (range.start === null || range.stop === null) {
if (range.start === null) {
range.start = new Date(dateText);
} else {
range.stop = new Date(dateText);
}
}
if (range.start !== null && range.stop !== null) {
if ($this.find('td').hasClass('selected')) {
//clear selected range
$this.children().removeClass('selected');
range.start = new Date(dateText);
range.stop = null;
//call internal method '_updateDatepicker'.
inst.inline = true;
} else {
//prevent internal method '_updateDatepicker' from being called.
inst.inline = false;
if (range.start > range.stop) {
d = range.stop;
range.stop = range.start;
range.start = d;
}
sel = (range.start.toString() === range.stop.toString()) ? 0 : (new Date(range.stop - range.start)).getDate();
for (i = 0; i <= sel; i += 1) {
ds = (range.start.getMonth() + 1).toString() + '/' + (range.start.getDate() + i).toString() + '/' + (range.start.getFullYear()).toString();
d = new Date(ds);
$this.find('td a').filter(function(index) {
return $(this).text() === d.getDate().toString();
}).parents('td').addClass('selected');
}
}
}
}
});
});
I became desperate and came up with a solution on my own. It wasn't pretty but I'll detail it.
I was able to construct a div that had the text boxes, buttons and the datepicker that looked like the Google Analytics control but I couldn't make the datepicker work properly. Eventually, I came up with the idea of creating a toggle variable that kept track of which date you were selecting (start date or end date). Using that variable in a custom onSelect event handler worked well but I still couldn't figure out how to get the cells between dates to highlight.
It took a while, but I slowly came to the realization that I couldn't do it with the datepicker as it existed out of the box. Once I figured that out, I was able to come up with a solution.
My solution was to add a new event call afterSelect. This is code that would run after all the internal adjustments and formatting were complete. I then wrote a function that, given a cell in the datepicker calendar, would return the date that it represented. I identified the calendar date cells by using jQuery to find all the elements that had the "ui-state-default" class. Once I had the date function and a list of all the calendar cells, I just needed to iterate over all of them and, if the date was in the correct range, add a new class to the parent.
It was extremely tedious but I was able to make it work.
