I am trying to get the number of new users for each week using the created_at column. I am trying to use the whereBetweensyntax but it always return 0 even when it is suppose to return otherwise.
{{ DB::table('users')
->whereBetween('created_at', array(date("Y/m/d h:i:s", strtotime('sunday last week')), date("Y/m/d h:i:s", strtotime('saturday this week'))))->count(); }}
Any suggestions?
The query itself should work as written, though you might want to verify that created_at is a column of either timestamp, date, or datetime type. When you created the users table, did you use a migration to create your users table, and if so, did you specify $table->timestamps();? Or did you manually define the created_at column, and perhaps set it to a string?
A couple other (unrelated) suggestions:
• It appears that you're running this query in a view, echoing the count using blade. This logic would be better handled elsewhere, perhaps in your User model, and the result passed to the view by the controller.
• You can simplify your query using PHPs DateTime object, replacing your date(...strtotime...) with date_create(...):
$usersThisWeek = User::whereBetween(
'created_at', array(
date_create('sunday last week'),
date_create('saturday this week')
))->count();

Is there any way to put a manual function inside a query in Laravel.
I've timestamp saved in string in DB. I want to convert timestamp from one timezone to another. All the timestamp is inserted in one time zone, and depending upon my user I fetch the timestamp and convert it into their timezone.
what I want to achieve is something like this..
$query = BlogCategory::select('merchant_id', userTime(added_at))
->where('site_id', $site_id)
->get();
userTime() function takes two parameter, the timestamp and the timezone and converts the timsestamp to time of the user.
I want to use userTime() function before fetching the data. I dont want to fetch the data first and then do foreach and so on.
I know I might be absolutely absurd but is there anything of this sort in Laravel?
Well you can achieved that using collection map
$query = BlogCategory::select('merchant_id', 'added_at')
->where('site_id', $site_id)
->get();
$dateAdded = $query->map(function ($data) {
// try this if error $data['merchant_id']
return array(
'merchant_id' => $data->merchant_id,
'added_at' => $this->userTime($data->added_at)
);
})
dd($dateAdded);
Read Collection documentation here: https://laravel.com/docs/5.8/collections
You should use the selectRaw statement and let your DB do this logic for you if you don't want to loop over the result set.
For example if your underlying database is MySQL you can use the CONVERT_TIMEZONE function and do something like this.
BlogCategory::selectRaw('merchant_id, CONVERT_TZ(added_at, "GMT", "MET") as added_at')
->where('site_id', $site_id)
->get();
I am having a little trouble comparing dates in Laravel, where the date is a specific format.
The field in the database has the date like this d-m-Y(20-04-2018) and I am trying to get a result where this date is greater than the date now using this.
$check= Usersubstitutions::where([
['user_id', '=', $request->user],
['date_to', '>=', date("d-m-Y")]
])->first();
And it never works. I var dumped to see what compares, using a foreach and it says that 20-05-2018 is NOT greater than 04-04-2018.
Convert your column to a date format, such as DATE, and then it will work as intended.
Since your field is a varchar try to cast it first to DATE then compare it with date('d-m-Y') like :
$check= Usersubstitutions::where('user_id', $request->user)
->where(DB::raw("DATE(date_to) >= '".date('d-m-Y')."'"))
->first();
NOTE : It will be better to convert the field type in your database to 'DATE'.
On Laravel 4+ you may use
->whereDate('date_to', '>=', date("d-m-Y")
For more examples, see first message of #3946 and this Laravel Daily article.
but you may also use the ->where() as its more convenient.
Try this:
$dayAfter = (new date()->modify('+1 day')->format('d-m-Y');
->where('date_to', '>=', $dayAfter)
Hope it helps. if not view this qn for further explanations
You seem to be storing a DATE in a varchar field. That's not a good idea. You need to either re-create the table and store date_to as a date using the standard SQL DATE format (and use the format Y-m-d when inserting) or cast the column to a date when selecting:
$check= Usersubstitutions::where([
['user_id', '=', $request->user],
[\DB::raw("STR_TO_DATE(date_to,'%d-%m-%Y')") ', '>=', date("Y-m-d")]
])->first();
Note this will make any indexes useless and will make the query run very very (very) slowly.
Note: STR_TO_TIME is MySQL only but there are equivalents in other DBMSs e.g. in SQL Server it seems to be CONVERT(DATE, date_to, 105)
I have a block of code in which I am passing a Carbon date that looks like this:
2017-08-18 22:53:50.031922
And want to compare it to created_at time stamps of some records. However, it seems that the records are not being filtered out; is the comparison in the where statement valid?
$test = Auth::user()->tests()->with([
'participants.testRecords' => function ($query) use ($latestCapture) {
$query->select('id', 'score', 'test_id', 'participant_id', 'capture_timestamp', 'score', 'created_at');
$query->where('test_records.created_at', '>', $latestCapture);
}])->findOrFail($id)->toArray();
If $latestCapture is instancej Carbon, you should rather use here:
$latestCapture->toDateTimeString()
to make sure you pass valid date string.
There is also one more thing - you should make sure created_at is filled in PHP and not in MySQL (this is default in Laravel) - if it's not you can expect time shifts when you have different time zones in PHP and MySQL
I have a collection called $products, each instance of which has a field created_at. The latter obviously has a format ('Y-m-d H:i:s') in the DB. Now, it's easy to get instances with unique created_at. However, I'd like to retrieve unique year values of created_at in one single expression (that I can write in my view). What I am looking for is:
$products->unique( year value ('Y' ONLY) of 'created_at' )
This expression should evaluate to something like this: ['2012', '2013', '2016'].
Building on the comment that gives you a collection with unique timestamps, you can map out the year and sort with the following code.
$years = $products->unique(function($item){
return $item['created_at']->year;
})->map(function($item){
return $item['created_at']->year;
})->sort()->toArray();
In addition to Tim result
$products = DB::table('products')->get();
$years = $products->unique(function($item){
return $item['created_at']->year;
})->map(function($item){
return $item['created_at']->year;
})->sort()->toArray();
You can use toArray or values() to get the result of collection
Im using Eloquent. But I'm having trouble understanding Eloquent syntax. I have been searching, and trying this cheat sheet: http://cheats.jesse-obrien.ca, but no luck.
How do i perform this SQL query?
SELECT user_id FROM notes WHERE note_id = 1
Thanks!
If you want a single record then use
Note::where('note_id','1')->first(['user_id']);
and for more than one record use
Note::where('note_id','1')->get(['user_id']);
If 'note_id' is the primary key on your model, you can simply use:
Note::find(1)->user_id
Otherwise, you can use any number of syntaxes:
Note::where('note_id', 1)->first()->user_id;
Note::select('user_id')->where('note_id', 1)->first();
Note::whereNoteId(1)->first();
// or get() will give you multiple results if there are multiple
Also note, in any of these examples, you can also just assign the entire object to a variable and just grab the user_id attribute when needed later.
$note = Note::find(1);
// $user_id = $note->user_id;
