I'm developing a report system, and I want to fetch users who did not report for six (6) consecutive months. How do I achieve this?
I've tried the code below but I'm not getting the desired output. There is also a problem. Let's say the date interval is 12 months. How can I determine if there is no report for 6 consecutive months?
$dateStart = '2018-10-31';
$dateEnd = '2019-03-31';
$intervals = Carbon::parse($dateStart)->diffInMonths($dateEnd);
$users = $users->whereDoesntHave('reports', function($query) use($intervals) {
for ($i = 5; $i >= 0; $i--) {
$firstMonth = Carbon::parse($dateEnd)->subMonthsNoOverflow($intervals);
$query->where('date', '>=', $firstMonth->format('Y-m-d'))->where('date', '<=', $dateEnd);
}
});
What I will do is that I will create a loop per month based on the start and end date, then check if he did not have a report for that month. If it doesn't have a report for that month, I will increment a counter, and if that counter reaches 6 counts, exit the loop and the condition was satisfied.
Below is the basic idea:
$dateStart = '2018-10-31';
$dateEnd = '2019-10-31';
$count = 0;
$no_report_for_6_consecutive_months = 0 ;
startloop
$have_report = Model::whereMonth('date_column', $date_of_loop->format('m'))->get();
if($have_report->count()){
$count = 0;
}
else{
$count++;
}
if($count==6){
$no_report_for_6_consecutive_months = 1 ;
break;
}
endloop
You have to find distinct users who report for six (6) consecutive and get difference with all users.
$enddate = 2019-04-15;
$startdate = date("Y-m-d", strtotime("-6 months", strtotime($enddate)));
$users = User::all();
$usersIdArray = $users->pluck("id")->all();
$reportedBy = Report::where('date', '>=', $startdate)
->where('date', '<=', $enddate)
->distinct("user_id")->get();
$reportedByIdArray = $reportedBy ->pluck("id")->all();
$notReportedByIdArray = array_values(array_diff($usersIdArray , $reportedByIdArray));
$notREportedUsers = User::whereIn(id", $notReportedByIdArray)->get();
//its a way but not tested
I have modified the query from this answer
I believe the query can be wrote cleaner. I will let you do this if you want to.
App\User::select('*')
->from(\DB::raw("(select
low.*,
low.`date` as date_start,
high.`date` as date_end,
to_days(high.`date`) - to_days(low.`date`) as day_gap,
period_diff(date_format(high.`date`, '%Y%m'),
date_format(low.`date`, '%Y%m')) as month_gap
from reports low, reports high
where high.`date` =
(select
min(`date`)
from reports
where
`date` > low.`date`
and low.user_id = high.user_id
)
) as d")
)->get();
Now you will get all the users with 4 extra fields: date_start; date_end, day_gap and month_gap
If you want the users with a month gap of 6 months you can do this:
App\User::select('*')
->from(\DB::raw("..."))
->where('month_gap', '>=', 6)
->get();

I want to get 7 latest rows (in order from down to up), for the current week (Sunday to Saturday), for the current logged in user.
To do this, I used this one method:
Carbon::setWeekStartsAt(Carbon::SUNDAY);
Carbon::setWeekEndsAt(Carbon::SATURDAY);
$strikes = UserStrike::where('user_id', $user)->whereBetween('created_at', [Carbon::now()->startOfWeek(), Carbon::now()->endOfWeek()])->latest()->take(7)->get();
$strikes = $strikes->reverse(); //to order the list from DESC to ASC
But the problem with this method is that it doesn't get any missing days.
So if there are data like this for the current week (2020-05-12 is missing):
created_at: 2020-05-10
created_at: 2020-05-11
created_at: 2020-05-13
Then for that one day which is missing, there should be a null in array. Something like this:
$days = ["Sun", "Mon", null, "Wed"];
I'm having hard time to find a way to replace missing day with a null in array.
If anyone here can help me with this problem please leave your comment. Thank you in advance.
You can take data from DB and then create array by iterating on DateTimeInterval(). I don't know Laravel and Carbon well but it could be something like this:
Carbon::setWeekStartsAt(Carbon::SUNDAY);
Carbon::setWeekEndsAt(Carbon::SATURDAY);
$start = Carbon::now()->startOfWeek();
$end = Carbon::now()->endOfWeek();
$strikes = UserStrike::where('user_id', $user)
->whereBetween(
'created_at',
[$start, $end]
)
->latest()
->take(7)
->get();
$strikes = $strikes->reverse();
$timePeriod = new DatePeriod(
$start,
new DateInterval('P1D'),
$end
);
$days = [];
for ($i = 0; $i < count($timePeriod) $i++) {
$days[$i] = null;
foreach ($strikes as $strike) {
if ($strike->created_at->format('Y-m-d') == $timePeriod[$i]->format('Y-m-d') {
$days[$i] = $strike->created_at->format('Y-m-d');
break;
}
}
}
UseCase: Admin assigns tasks to People. Before we assign them we can see their tasks in a gantt chart. According to the task assign date and deadline, conflict days (overlap days) are generated between tasks.
I wrote this function to get overlapping dates between two dates. But now I need to get non overlapping days between two dates, below is the function I wrote.
$tasks = Assign_review_tasks::where('assigned_to', $employee)
->where('is_active', \Constants::$REVIEW_ACTIVE)
->whereNotNull('permit_id')->get();
$obj['task'] = count($tasks);
// count($tasks));
if (count($tasks) > 0) {
if (count($tasks) > 1) {
$start_one = $tasks[count($tasks) - 1]->start_date;
$end_one = $tasks[count($tasks) - 1]->end_date;
$end_two = $tasks[count($tasks) - 2]->end_date;
$start_two = $tasks[count($tasks) - 2]->start_date;
if ($start_one <= $end_two && $end_one >= $start_two) { //If the dates overlap
$obj['day'] = Carbon::parse(min($end_one, $end_two))->diff(Carbon::parse(max($start_two, $start_one)))->days + 1; //return how many days overlap
} else {
$obj['day'] = 0;
}
// $arr[] = $obj;
} else {
$obj['day'] = 0;
}
} else {
$obj['day'] = 0;
}
$arr[] = $obj;
start_date and end_date are taken from database,
I tried modifying it to,
(Carbon::parse((min($end_one, $end_two))->add(Carbon::parse(max($start_two, $start_one))))->days)->diff(Carbon::parse(min($end_one, $end_two))->diff(Carbon::parse(max($start_two, $start_one)))->days + 1);
But it didn't work, in simple terms this is what I want,
Non conflicting days = (end1-start1 + end2-start2)- Current overlapping days
I'm having trouble translate this expression . Could you help me? Thanks in advance
before trying to reimplement complex stuff I recommend you take a look at enhanced-period for Carbon
composer require cmixin/enhanced-period
CarbonPeriod::diff macro method is what I think you're looking for:
use Carbon\CarbonPeriod;
use Cmixin\EnhancedPeriod;
CarbonPeriod::mixin(EnhancedPeriod::class);
$a = CarbonPeriod::create('2018-01-01', '2018-01-31');
$b = CarbonPeriod::create('2018-02-10', '2018-02-20');
$c = CarbonPeriod::create('2018-02-11', '2018-03-31');
$current = CarbonPeriod::create('2018-01-20', '2018-03-15');
foreach ($current->diff($a, $b, $c) as $period) {
foreach ($period as $day) {
echo $day . "\n";
}
}
This will output all the days that are in $current but not in any of the other periods. (E.g. non-conflicting days)
Heei, I want to show data according to daterange. Specifically data on this day and 6 days to go. Here's my code now.
Controller
$hari = [];
for ($i=0; $i < 6; $i++)
{
$hari[] = date("Y M d") + $i;
}
$booking_room = jadwal_meeting::whereBetween('tanggal', [$hari, $hari + 6])->get();
return view('homepage')->with($booking_room);
Note: 'tanggal' is a field on table.
But I just get error like this
Unsupported operand types
: $booking_room = jadwal_meeting::whereBetween('tanggal', [$hari, $hari + 6])->get();
What's wrong with my code, anyone can help me please :)
Since $hari is an array, you have to use something like this:
$booking_room = jadwal_meeting::whereBetween('tanggal', [$hari[0], $hari[5]])->get();
Or more general:
$booking_room = jadwal_meeting::whereBetween('tanggal', [$hari[0], end($hari)])->get();
Try this code it will help you.
$from = '2018-04-12';
$to = date('Y-m-d', strtotime($from. ' + 6 days'));
$reservations = Reservation::whereBetween('tanggal', [$from, $to])
->get();
Thanks,
I have a database table
TABLE subject_loads
id (int)
subject_name (varchar)
time_start (time)
time_end (time)
time_diff (decimal)
When I save it on database, it will first check whether the time is not conflicting from the other time already inputed. If it's okay, then compute the time_start and time_end to give me a difference between the two.
Example, 7:30 AM - 8:30 AM is already in database, when i input 8:00 AM - 9:00 AM it will say "conflicting with the other time". Only I can input before 7:30 AM or after 8:30 AM that doesn't overlap from 7:30 AM - 8:30 AM.
Can someone help on how to do this?
First you need to check if overlapping values (compared to new value) already exist. You will do that with:
$query = $this->db->get_where('subject_loads', array('time_start >= ' => $time_start, 'time_end <= ' => $time_end));
if((int)$query->num_rows() > 0)
{
//similar values exist
}
else
{
//you are free to insert values
}
Second part of issue:
$hm1 = "2:12 AM";
$hm2 = "4:41 PM";
$e = conv($hm2) - conv($hm1);
echo $e;
function conv($time)
{
$expl_time = explode(' ', $time);
$t = explode(":", $expl_time[0]);
if ($expl_time[1] == 'PM' || $expl_time[1] == 'pm')
{
$t[0] += 12;
}
return ($t[0] + round($t[1]/60, 1, PHP_ROUND_HALF_UP));
}
I'm building a booking form for a moving business that uses a calendar combined with a start and end time. I built the timepicker with Formidable Pro, and it allows me to check "unique" on time fields which automatically removes them on the selected date. However it doesn't automatically remove the times from within the range between start and end times (ie: if someone chooses to rent a truck from 1am-3am I need 1am,2am,and 3am to be removed from future options but right now it only removes 1am and 3am) . I need to write ajax to remove the in-between times from the options. I'm not sure where to begin. This is the current ajax_time_ options function. Any push in the right direction would be appreciated.
function ajax_time_options(){
global $frmpro_settings, $frmdb, $wpdb;
//posted vars = $time_field, $date_field, $step, $start, $end, $date, $clock
extract($_POST);
$time_key = str_replace('field_', '', $time_field);
$date_key = str_replace('field_', '', $date_field);
if (!preg_match('/^\d{4}-\d{2}-\d{2}$/', trim($date)))
$date = FrmProAppHelper::convert_date($date, $frmpro_settings->date_format, 'Y-m-d');
$date_entries = FrmEntryMeta::getEntryIds("fi.field_key='$date_key' and meta_value='$date'");
$opts = array('' => '');
$time = strtotime($start);
$end = strtotime($end);
$step = explode(':', $step);
$step = (isset($step[1])) ? ($step[0] * 3600 + $step[1] * 60) : ($step[0] * 60);
$format = ($clock) ? 'H:i' : 'h:i A';
while($time <= $end){
$opts[date($format, $time)] = date($format, $time);
$time += $step;
}
if($date_entries and !empty($date_entries)){
$used_times = $wpdb->get_col("SELECT meta_value FROM $frmdb->entry_metas it LEFT JOIN $frmdb->fields fi ON (it.field_id = fi.id) WHERE fi.field_key='$time_key' and it.item_id in (". implode(',', $date_entries).")");
if($used_times and !empty($used_times)){
$number_allowed = apply_filters('frm_allowed_time_count', 1, $time_key, $date_key);
$count = array();
foreach($used_times as $used){
if(!isset($opts[$used]))
continue;
if(!isset($count[$used]))
$count[$used] = 0;
$count[$used]++;
if((int)$count[$used] >= $number_allowed)
unset($opts[$used]);
}
unset($count);
}
}
echo json_encode($opts);
die();
