I have list of months, and now i want to count articles for every month.
I have this :
$data= Articles::get()
->groupBy(function($item) {
return $item->created_at->month;
});
And for now i get data for 11 and 12, but how can i do that so that i can have list of month names and next to them have number of articles for that month?
foreach ($data as $key => $values) {
$data[$key] = $values->count();
}
$data = $clicked->toArray();
This will give you the number of articules by Month and if you want the month name as the key then
group by
$item->created_at->format('M')
instead of your group by condition

I just wanted to extract unique year value from this date type column. But I always get this error "You might need to add explicit type casts".
If there are 2020-06-23, 2020-07-01, 2019-01-02, 2019-02-05 dates, my desired output is to return the unique year values. So the output should be 2020 and 2019 only.Please help. Thank you.
Here is my code:
$year= DB::table('loans')
->select('date_release', DB::raw('YEAR(date_release) as year'))
->groupBy('year')
->get();
The query could be (returns all when there are different dates from different years);
SELECT EXTRACT(YEAR FROM loans.date_release) AS year FROM loans group by year;
The query builder will be
return DB::table('loans')
->select([DB::raw('EXTRACT(YEAR FROM loans.date_release) as year')])
->groupBy('year')
->pluck('year');
it prints following for multiple years
[2018, 2019, 2020]
I think that there are only 2 ways to get what you want
first you need add another column with name year and store data only year and your query will be like this
return DB::table('loans')
->select('year')->distinct('year');
second one is before return you should some algorithm to extract year and return only distinct year it will be like this
$year = DB::table('loans')
->select([DB::raw('YEAR(date_release) as year')])
->groupBy('year')
->value('year');
$distinct_year = array();
foreach($year as $item){
$years = date('Y', strtotime($item->year))
if(!in_array($years, $distinct_year)){
array_push($distinct_year, $years);
}
}
return $distinct_year;
I have an eloquent query that gets the total count records (created_at) of the last 7 days. But the problem is if one of these days have 0 records, this doesn't appear in the final data.
My query:
$data = Data::whereBetween('created_at', [Carbon::now()->subDays(6)->format('Y-m-d')." 00:00:00", Carbon::now()->format('Y-m-d')." 23:59:59"])
->groupBy('date')
->orderBy('date')
->get([
DB::raw('DATE(created_at) as date'),
DB::raw('count(*) as total')
])
->pluck('total', 'date')->toArray();
What I get:
[
"2020-04-14" => 1
"2020-04-16" => 1
"2020-04-18" => 1
"2020-04-19" => 1
]
What I expected:
[
"2020-04-14" => 1
"2020-04-15" => 0
"2020-04-16" => 1
"2020-04-17" => 0
"2020-04-18" => 1
"2020-04-19" => 1
"2020-04-20" => 0
]
Any suggestions?
SOLUTION:
-Based on Gary Houbre's proposal:
$results = Data::whereBetween('created_at', [Carbon::now()->subDays(6)->format('Y-m-d')." 00:00:00", Carbon::now()->format('Y-m-d')." 23:59:59"])
->groupBy('date')
->orderBy('date')
->get([
DB::raw('DATE_FORMAT(created_at, "%Y-%m-%d") as date'),
DB::raw('count(*) as total')
])
->keyBy('date')
->map(function ($item) {
$item->date = Carbon::parse($item->date);
return $item;
});
$period = new DatePeriod(Carbon::now()->subDays(6), CarbonInterval::day(), Carbon::now()->addDay());
$graph = array_map(function ($datePeriod) use ($results) {
$date = $datePeriod->format('Y-m-d');
return $results->has($date) ? $results->get($date)->total : 0;
}, iterator_to_array($period));

Into a same table : How to get the record if Count is zero in Laravel
You need to add an outer join into your request with Eloquent.
My idea is to create a for loop to check the days.
If there is no record on a date then print 0
Loop Iteration:
Catch the first Day (Suppose 14)
Catch the last Day
Then check in every iteration it is greater than one or many
Thus, I hope you will get normally.
We had a similar problem while trying to put back-end data into the chart. Since some of the days were missing it didn't look well. Our solution was;
Create a function like this;
public function generateDates(Date $startDate, Date $endDate, $format = 'Y/m/d'): Collection
{
$dates = collect();
$startDate = $startDate->copy();
for ($date = $startDate; $date->lte($endDate); $date->addDay()) {
$dates->put($date->format($format), 0);
}
return $dates;
}
In your case it's going to be (today and today - six days) and you will union returning collection with your query collection. What it does is; it create a date range from the keys and fill them with zero. When your query collection has some value other than zero - it is going to overwrite it.
I am searching by start and end date or with a weekday, which kind of works fine however if weekday is equal to 'WE' and today's weekday is equal to 'WE' it still brings back results even when $today date is < than endate.
public function show($id)
{
$weekMap = [
0 => 'SU',
1 => 'MO',
2 => 'TU',
3 => 'WE',
4 => 'TH',
5 => 'FR',
6 => 'SA',
];
$todayWeek = Carbon::now()->dayOfWeek;
$today= Carbon::now();
$weekday = $weekMap[$todayWeek];
$event = Event::with('businesses')
->where('startdate', '<', $today->format('Y-m-d'))
->where('endate', '>', $today->format('Y-m-d'))
->orWhere('weekday', '=', $weekday)
->get();
dd($event);
return view('events.showEvent', compact('event'));
}
If I change orWhere to where, results are all good, however user not always enters a weekday so it can be empty. I want it to work like this:
output everything where startdate < today and where endate > today and if weekday is not empty, output everything where startdate < today, endate > today and weekday = $weekday. I hope that makes sense.
//edit
sample data:
data
So what I want is really search by frequency so it would look like this:
if frequency = daily
compare start and end with today's date.
if frequency = weekly
compare start and end with today's date and weekday.
bring back all results for frequency = daily+weekly
you can use if condition in query like this:
$query = Event::with('businesses')
->where('startdate', '<', $today->format('Y-m-d'))
->where('endate', '>', $today->format('Y-m-d'));
if ($weekday != '') {
$query->where('weekday', $weekday);
}
$event = $query->get();
also
condition if ($weekday != '') check $weekday isset or not you can use
if ( ! is_null($weekday )) instead
So getting a sum()/count() is really easy in Laravel...
but how would I look at the past month, and get the sum of rows every day?
EG...grouped by day that they were created at.
So I want to return a count such as 3, 2, 4, 5
Meaning 3 rows were created on todays date, 2 rows yesterday, 4 rows the day before...etc
How to do this in Laravel easily?
When I use the group by created_at it always just returns 1.
Anybody know how to do it?
Thanks
I've provided the same answer on another post. Shortening it:
$date = new DateTime('tomorrow -1 month');
// lists() does not accept raw queries,
// so you have to specify the SELECT clause
$days = Object::select(array(
DB::raw('DATE(`created_at`) as `date`'),
DB::raw('COUNT(*) as `count`')
))
->where('created_at', '>', $date)
->group_by('date')
->order_by('date', 'DESC')
->lists('count', 'date');
// Notice lists returns an associative array with its second and
// optional param as the key, and the first param as the value
foreach ($days as $date => $count) {
print($date . ' - ' . $count);
}
how to get all products between two dates like last month products, this month products , last week products and this week products etc.
i tried with this:
// current day to start with
$start = mktime(0,0,0,date('m'), date('d'), date('Y'));;
// calculate the first day of last month
$first = date('YYYY-MM-DD',mktime(0,0,0,date('m',$start) - 1,1,date('Y',$start)));
// calculate the last day of last month
$last = date('YYYY-MM-DD',mktime(0, 0, 0, date('m') -1 + 1, 0, date('Y',$start)));
if($filter == "lastmonth"){
$collection = Mage::getModel('catalog/product')->getCollection();
$collection->addAttributeToFilter('updated_at', array('gteq' =>$first));
$collection->addAttributeToFilter('updated_at', array('lteq' => $last));
}
but i am not able to get the result :( any help ?
Modified after Daniel response !
1) First of all you need to change you date formate from 'YYYY-MM-DD' to 'Y-m-d'. This will return a date formate which magento records have.
2) There is a special condition for date as bellow mention with your example.
$collection = Mage::getModel('catalog/product')->getCollection();
$collection->addAttributeToFilter('updated_at', array('gteq' =>$first));
$collection->addAttributeToFilter('updated_at', array('lteq' => $last));
To.
$collection = Mage::getModel('catalog/product')->getCollection();
$collection->addAttributeToFilter('updated_at', array(
'from' => $first,
'to' => $last,
'date' => true,
));
I tried your code and had to swap 'lteq' and 'gteq' to make it work. The $fromdate is the lower number so you are searching for dates greater than that number.
Also you must remember to format the dates as MySQL likes it; date('Y-m-d').
PS. See the comparison operators for a full list
There is one issue with your code:
$collection->addFieldToFilter()
should be:
$collection->addAttributeToFilter()
I know that the question is little bit old but as it is quite well ranked in search engine results, I will correct the date() function that better take as arguments something like : Y-m-d H:i:s.
I hope it will help !
