I have a controller function named updateoos(), a model for that function Outofserviceday and a table named outofservicedays. The table has 3 fields - id, userid, outofservicedays.
I want to get the out of service days from today to the last day of month
how to write a function in Outofserviceday model with two arguments today and monthedDday like.
function ($today $monthedDday) { }
In my controller I get the two dates
$today = date("Ymd");
$monthend=date("ymd", strtotime($today));
I edited all my mistakes
Just convert your times to unix timestamp and check the values against your target dates.
Example:
$no_service_days = $this-> Outofserviceday->find('all');
$nsd_array = array();
$end_date = strtotime($monthend); // or strtotime('31-01-12');
foreach ($no_service_days as $key => $day) :
$record_u_time = strtotime($day['Outofserviceday']['outofservicedays']);
if($record_u_time < $end_date){
$nsd_array[] = $day;
}
endforeach;
pr($nsd_array);
This is a loose approach to the technique you should use since your code and naming conventions are honestly pretty confusing.
I don't see a date field in your table so I assume it's outofservicedays and your $monthend=date("ymd", strtotime($today)); doesn't appear to be a date in the future or past.

This is my first post. I am in a trouble in my laravel project
Here is my data table.
I have student Id like 1,2,3. every students have multiple results followed by courses.
I need to arrange them like that
I tried groupby and got this result
Is there any possible way to arrange them according to students.
Thank You
code: controller:
public function notification()
{
$auth_id = Auth::user()->id;
$teacher = Teacher::where('user_id', $auth_id)->first();
$teacher_id = ($teacher->id);
$batch = Batch::where('teacher_id', $teacher_id)->first();
$courses = AssignCourses::with('course')
->where('semester_id', $batch->semester_id)
->get();
$current_semester_results = Result::with(['student', 'course'])
->where('semester_id', $batch->semester_id)
->get()
->groupBy('student.id');
$batch_students = Student::with('result')
->where('semester_id', $batch->semester_id)
->get();
return view('users.teacher.my_batch.notification', compact(['current_semester_results', 'courses', 'batch_students']));
}
Just use the $batch_students and apply any aggregations on your PHP code, it is easier to do it.
$batch_students = Student::with('result')
->where('semester_id', $batch->semester_id)
->get();
$batch_students_grouped = $batch_students->groupBy('result.student_id');
Note: I could not test since I don't have the tables, so you might need to change the student_id nest/access index in the last line of code.
you can print out your $batch_students_grouped->all() and see how you should iterate your data and show it in frontend.
Hi I am trying to get customer _id from different tables Purchase order ,Sale Order and Consignments
Then I am looping through these Ids . Method I am using for this purpose is working perfectly but . I am afraid if there is a lot of data this method may get failed. Here is my method .
$consignmentCustomerIds = Consignment::select('customer_id')->where('is_repeat', 0)->whereDate('created_at','>',date('2021-03-06'))->whereRaw('(is_group = "parent" or is_group is null)')->where('finalize', 0)->where('invoice_id', null)->distinct()->pluck('customer_id')->toArray();
$poCustomerIds = PurchaseOrder::select('customer_id')->whereDate('created_at','>',date('2021-03-06'))->where('invoice_id', null)->distinct()->pluck('customer_id')->toArray();
$soCustomerIds = SaleOrder::select('customer_id')->whereDate('created_at','>',date('2021-03-06'))->where('invoice_id', null)->distinct()->pluck('customer_id')->toArray();
$spCustomerIds = StoragePeriod::select('customer_id')->whereDate('created_at','>',date('2021-03-06'))->where('invoice_id', null)->distinct()->pluck('customer_id')->toArray();
$ids = array_merge($consignmentCustomerIds, $poCustomerIds, $soCustomerIds, $spCustomerIds);
$customers = Customer::whereIn('id', $ids)->get();
foreach ($customers as $customer) {
CreateInvoiceOneByOne::dispatch($customer)->onQueue('invoice');
}
Is there any better way of doing so?
The main thing is to change ->get() to ->cursor() in the iteration:
// $customers = Customer::whereIn('id', $ids)->get();
$customers = Customer::whereIn('id', $ids)->cursor();
The cursor method may be used to significantly reduce your application's memory consumption when iterating through tens of thousands of Eloquent model records.
More info: https://laravel.com/docs/8.x/eloquent#cursors
IF YOUR RELATIONS ARE SET PROPERLY
I suggest to reduce database query. You can do this by chaning whereHas and orWhereHas within the customer request.
Querying Relationship Existence
$date = date('2021-03-06');
$customers = Customer::whereHas('consignment', function($query) use($date) {
$query->where('is_repeat', 0)->whereDate('created_at','>',$date)->whereRaw('(is_group = "parent" or is_group is null)')->where('finalize', 0)->where('invoice_id', null);
})->orWhereHas('purchase_order', function($query) use($date) {
$query->whereDate('created_at','>',$date)->where('invoice_id', null);
})->orWhereHas('sale_order', function($query) use($date) {
$query->whereDate('created_at','>',$date)->where('invoice_id', null);
})->orWhereHas('storage_period', function($query) use($date) {
$query->whereDate('created_at','>',$date)->where('invoice_id', null);
})->get();
foreach ($customers as $customer) {
CreateInvoiceOneByOne::dispatch($customer)->onQueue('invoice');
}
I set the $date variable before the query, so this way you can manipulate it at one place.
P.S. I am currently assuming the name of the relations.
I want to get the number of rows of a certain table considering a time frame.
I'm using CakePHP 3.7.
Here you can see my code (from the controller class) :
public function nbOfDefense($dateIn, $dateOut){
if($dateIn!=null && $dateFin!=null){
$conditions = array('thesis.date_end BETWEEN ? and ?' => array($dateIn, $dateOut));
$query = $this->Thesis->find('all',
array('conditions'=>$conditions));
die(strval($query->count()));
return $query;
}else{
$query = $this->Thesis->find('all');
die(strval($query->count()));
return $query->count();
}
}
I'm testing my function through my browser using this URL :
http://localhost:8888/thesis/nbOfDefense/2003-02-01/2019-04-13
What I want my function to do, is to, get in parameters two dates :
If those two dates are not null, you get the number of rows that between the two dates considering a date stored in the table you're consulting.
If the dates are null, then you get the total number of rows of the table.
And return an int, which is the number of rows that are between those two dates.
I feel like the problem here is how I handle my condition, because counting the total number of rows works perfectly (the else part of the code).
The error I have right now with this code is the following :
Cannot convert value of type array to string
it's pointing to this line :
die(strval($query->count()));
I guess the count function returns an array (weird because it doesn't when I count all rows without conditions). I also tried this :
die(strval(sizeof($query->count())));
But I get the same error as before (cannot convert array to string)
I must be missing something but I don't know what...
Try:
use Cake\ORM\Query;
use Cake\Database\Expression\QueryExpression;
class MyController extend AppController
{
public function nbOfDefense($dateIn = null, $dateOut = null)
{
$query = $this->Thesis->find();
if ($dateIn && $dateOut) {
$query->where(function (QueryExpression $exp, Query $q) use ($dateIn, $dateOut) {
return $exp->between('date_end', $dateIn, $dateOut);
});
}
$count = $query->count();
$this->set(compact('query', 'count'));
}
// ..
}

I have a product controller and when I'm saving a new product I want to save some records to another related controller to make a record of what categories the product is associated with.
My code I'm using is:
$this->Product->create();
if ($this->Product->save($this->request->data)) {
$newProductId = $this->Product->getInsertID();
//associate products with categories
foreach($categoriesToSave as $key=>$value) {
$saveArray['CategoriesProduct'] = array('category_id'=>$value, 'product_id'=>$newProductId);
$this->Product->CategoriesProduct->create();
$this->Product->CategoriesProduct->save($saveArray);
$this->Product->CategoriesProduct->clear();
}
}
For some reason though, even if $categoriesToSave has 10 items in it, only the very last one is being saved. So it's obviuosly creating only the one new CategoriesProduct item and saving each record over the top of the last instead of create()-ing a new one.
Can anyone explain what I'm doing wrong and how I can make this work?
The way I would do it would be like this:
//Add a counter
$c = 0
foreach($categoriesToSave as $key=>$value) {
$saveArray[$c]['CategoriesProduct']['category_id'] = $value;
$saveArray[$c]['CategoriesProduct']['product_id'] = $newProductId;
$c++;
}
$this->Product->CategoriesProduct->saveMany($saveArray);
I don't think that is the only way to do it but that should work just fine.
Good luck!
In my CakePHP forms_controller I have:
var $uses=array('Form','Field');
// ...
$this->set('retrived',$this->Field->find("all",array('conditions'=>array('Field.formname'=>$formname,))));
and in the view:
<?php foreach ($retrived as $r): ?>
<?php echo $r['Field']['fieldname']; ?><br>
<?php endforeach; ?>
I'm not getting the answer for it
Actually my table fields wil be like:
fieldname
formname
type
value
More details from my forms_controller:
function views()
{
if (!empty($this->params['form']))
{
$this->set('fieldctr',$this->params['form']['formfieldctr']);
$fieldctr=$this->params['form']['formfieldctr'];
if(!empty($this->params['form']['formnameelements']))
{
$this->set('formname',$this->params['form']['formnameelements']);//formname
$this->Form->saveField('name',$this->params['form']['formnameelements']);
}
else
{
$this->set('formname','MyForm');//formname
$this->Form->saveField('name','MyForm');
}
$this->Form->saveField('body',$this->params['form']['formelements']);//inserts into database
$ret = $this->Form->query("Select id from forms order by id DESC LIMIT 1");
$newid=$ret[0]['forms']['id'];echo $newid;
$upd=$this->Form->query("update forms set ctr=$fieldctr where id= $newid");
$formname=$this->params['form']['formnameelements'];
$n="$formname";
$array = $this->params['form']['formfieldnameelements'];
$comma_separated = explode(",", $array);
for($i=0;$i<$fieldctr;$i++)
{
echo $comma_separated[$i];
echo " ";
$n="$comma_separated[$i]";
//insert the fields of each form to the table fields
$this->data['Field']['fieldname'] = $comma_separated[$i];
$this->data['Field']['formname'] = $formname;
$this->Field->saveAll($this->data);
}
The above method is where I'm inserting the formname in my forms table.
And inserting that formname with their fieldsname in the fields table:
function formupdate()
{
$this->set('fieldctr',$this->params['form']['formfieldctr']);
$fieldctr=$this->params['form']['formfieldctr'];
$this->set('formname',$this->params['form']['formnameelements']);//formname
$formname=$this->params['form']['formnameelements'];
$ret = $this->Field->query("SELECT fieldname FROM fields WHERE fields.formname = "."'$formname'"."order by id ASC");
for($q=0;$q<$fieldctr;$q++)
{
$fieldname[$q]=$ret[$q]['fields']['fieldname'];
}
$this->set('retrived',$this->Field->find("all",array('conditions'=>array('Field.formname'=>$formname))));
$array = $this->params['form']['formfieldvalueelements'];
$comma_separated = explode(",", $array);
for($i=0;$i<$fieldctr;$i++)
{
echo $comma_separated[$i];
echo " ";
$n="$comma_separated[$i]";
echo $fieldname[$i];
$this->Field->updateAll(array('Field.value' => "'$comma_separated[$i]'"),array('Field.fieldname' => $fieldname[$i],'Field.formname'=>$formname));
}
$this->set('retrived',$this->Field->find("all",array('conditions'=>array('Field.formname'=>$formname,))));
} // end of function formupdate
In the above formupdate method I'm inserting the values of the corresponding values of that fields in the fields table... All the values are inserted correctly - but in my formupdate.ctp view:
Nothing is displayed in my view... eventhough the content is there in the table..
Please resolve my problem
By the names of your models, I think it's safe to conclude that you're trying to ouput some HTML. Since the question isn't really complete (where is the code?), we can't tell what's wrong with it.
A wild guess would be that something is being stripped there or ignored by your browser.
Aruna,
Please post the code you're using! It's possible that the error is something small, but without knowing what you're doing, it's impossible to help more than dr. Lecter did.
When you say that the fields table is updated correctly, do you mean that you can safely invoke the Model::save() method? Are you then calling Model::read() or Model::find() in the controller, then using the returned values from that to set a variable that can be accessed in the view?
