Laravel undefined variable when trying to pass data to view

Question

I am trying to pass data from my controller to my view, but am getting an undefined variable error. usersID is a column in my MySQL table.

Here is the code in my controller

$arrayWithCount = DB :: table("users_has_activities")
-> where("usersID", "=", 19)
-> pluck("usersID");

$countNumber = sizeof($arrayWithCount);

return view('pages.progress', ['countNumber' => $countNumber]);

I have also tried the following return statement without any success

return view::make('pages.progress') -> with('countNumber', $countNumber);

I have also tried reversing the puck and where clauses without any success, I didn't have high hopes that reversing them would fix the problem but thought I would try it any way. Below is the relevant code in the blade file.

 <?php echo $countNumber; ?>

This is the error I am currently getting

Undefined variable: countNumber

Try to dd($countNumber); before return view clause. What does it show? — Alexey Mezenin

I added a dd($countNumber); statement in my controller before I return the view but I still get the same error. Is there a special place I need to go to where I can see the result of dd($countNumber); ? — ray

Are you sure you're executing right method? Because dd() should display something and stop execution. Double check your routes and controllers. — Alexey Mezenin

You were right I had all the controller code in a method I wasn't calling, so the variable was never passed to the blade file. The method was set up to be called on a button press, after fixing that everything works. Thanks for your help — ray

You code looks fine, if dd() doesn't stop execution of the controller, then another controller is executing. So double check your routes and controllers.

First sizeof should be sizeOf, and is simply an alias for count(). Most people would prefer count over sizeOf as sizeOf (in many languages) would indicate something related to size on disk.

Anywho, being that pluck returns a collection, you have access to count() directly from the collection.

You can probably simply do something like:

$countNumber = $arrayWithCount->count();

Sidenote: Unless there is a particular reason why you are using <?php ?>, in blade, it would be preferred to use {{ and }}.

I tried using count() before but changed it to sizeOf() hoping it would fix the errors it did not. I corrected sizeOf() and also tried using $countNumber = $arrayWithCount->count(); but still get the same error.
