I have to arrays and I have to find difference values from it.
Here is my Laravel Controller code
$product_list = Operation::where('kvit_id', $kvit->id)->pluck('product_id')->toArray();
$hamkor_products = ListProduct::where('user_id', $newkvit->user_id)->pluck('product_id')->toArray();
$operProductList = array_diff($product_list, $hamkor_products);
dd($product_list, $hamkor_products, $operProductList);
Here is result which I'm getting
What kind of mistake I made? $operProductList is returns []
You must just change the order of parameters in array_diff(), it must be like :
$product_list = Operation::where('kvit_id', $kvit->id)->pluck('product_id')->toArray();
$hamkor_products = ListProduct::where('user_id', $newkvit->user_id)->pluck('product_id')->toArray();
$operProductList = array_diff($hamkor_products, $product_list);
dd($product_list, $hamkor_products, $operProductList);

Here's a problem that is bothering me for a while.
I have a service provider to pass data to all views, everytime the sidebar is rendered. like this:
`
public function boot()
{
$userrole = array (DB::table('users')->where('id','=', Auth::id())->value('role'));
$menucase1 = [3,4,9,10];
$menucase2 = [1,2,3,10];
$menucase3 = [1,3,4,9,10];
$menucase4 = [4,9];
$commondata = compact('userrole','menucase1','menucase2','menucase3','menucase4');
view()->share('commondata', $commondata);
View::composer('sidebar', function ($view) {
$userrole = array (DB::table('users')->where('id','=', Auth::id())->value('role'));
$menucase1 = [3,4,9,10];
$menucase2 = [1,2,3,10];
$menucase3 = [1,3,4,9,10];
$menucase4 = [4,9];
$commondata = compact('userrole','menucase1','menucase2','menucase3','menucase4');
$view->with('commondata', $commondata);
});
}`
Doing a {{ dd($commondata) }} returns the correct values for the menucase arrays, but NULL for the $userrole
If i declare the same $userrole variable in a controller and call the variable in the view, the received data is correct.
Why is this happening?
Thanks in advance
Can't understand what are you actually trying to do.
If you want get user role as array, you can using pluck method:
$userRole = User::where('id', Auth::id())->pluck('role')->toArray();
But for current user you can just get the role
$userRole = [Auth::user()->role];
UPD: you also can do it in view without any sharing
{{ Auth::user()->role }}
If your user has many roles from a different table, and you have the relationship defined, you could do
$userrole = Auth::user()->roles->pluck('name');
//will return all the roles names in an array
//Replace name by the actual column you want from 'roles' table.
Up until now I have been creating var inside the classes I made. e.g.
var backpack:Array = new Array("food", "water");
I want to create objects dynamically now like:
player = {};
player.backpack = ("food", "water"); // not the right syntax
OR
player = {backpack:Array = new Array("food", "water")} // not right either.
Any help? Thanks in advance. I can do this with simple vars like int, but can't find the answer to arrays.
ActionScript's generic object properties don't have any variable type associated with them. You assign them one of the following ways.
Example 1
player = {backpack: new Array("food", "water")};
Example 2
player.backpack = new Array("food", "water");
Example 3
player["backpack"] = new Array("food", "water");
You can use square brackets to define literal arrays. Not only is it shorter, but it's also faster (see this post).
The correct syntax for your two examples are
player = {};
player.backpack = ["food", "water"];
and
player = {backpack: ["food", "water"]};
Also, if you find it easier, you can use it in the first line of code you wrote.
var backpack:Array = ["food", "water"];
Please consider the following documentation:
http://livedocs.adobe.com/coldfusion/8/htmldocs/help.html?content=CFScript_11.html#1161053
I'm studying the description of following code:
<cfscript>
//Set the variables
acceptedApplicants[1] = "Cora Cardozo";
acceptedApplicants[2] = "Betty Bethone";
acceptedApplicants[3] = "Albert Albertson";
rejectedApplicants[1] = "Erma Erp";
rejectedApplicants[2] = "David Dalhousie";
rejectedApplicants[3] = "Franny Farkle";
applicants.accepted=acceptedApplicants;
applicants.rejected=rejectedApplicants;
rejectCode=StructNew();
rejectCode["David Dalhousie"] = "score";
rejectCode["Franny Farkle"] = "too late";
The description says that, "Creates two one-dimensional arrays, one with the accepted applicants and another with the rejected applicants. "
I'm new to ColdFusion and I don't see any array declaration using the array keyword in the above code just like the following doc:
http://livedocs.adobe.com/coldfusion/8/htmldocs/help.html?content=arrayStruct_03.html#1121128
Please explain.
You need to initialize your acceptedApplicants and rejectedApplicants arrays
There should be
acceptedApplicants = [];
rejectedApplicants= [];
somewhere above in the code. Like Peter said, if this is in a function make sure you var those variables.
I use socket.io version 0.8.4
I have boiled down my problem to the following. I have data looking like this:
data.prop1 = [];
data.prop1.push("man");
data.prop2 = [];
data.prop2["hey"] = "man";
I send the data from the server to the client this way:
socket.emit("data", data);
On the client side I receive the data this way:
socket.on("data", function(data){ console.log(data); });
The weird thing is:
data.prop1 = [];
data.prop1.push("man"); // This data exists in the client side data object
data.prop2 = [];
data.prop2["hey"] = "man"; // This data does not exist.
data.prop2 is just an empty array on the client side.
Is there a known bug in json serializing arrays on the form in prop2?
Thankyou in advance
EDIT:
Problem solved using this workaround:
data.prop1 = [];
data.prop1.push("man");
data.prop2 = {}; // <= Object instead of array
data.prop2["hey"] = "man";
ECMA-262 about JSON.stringify:
The representation of arrays includes only the elements between zero and array.length – 1 inclusive. Named properties are excluded from the stringification.
Arrays are supposed to have numerical property names. So when the data.prop2 is transformed to JSON (which socket.io sends the data in, I imagine), it doesn't get the 'hey' property. If you want to use non-numerical property names, you should use objects instead of arrays:
data.prop1 = [];
data.prop1.push("man");
data.prop2 = {}; // Notice we're creating an object, not an array.
data.prop2["hey"] = "man"; // Alternatively: data.prop2.hey = "man"
Unfortunately, Javascript doesn't really work like that.
Check out this article, about half way down. It explains the problem where you try to set data.prop2["hey"] = "man";
I'm curious, is there another way to convert a struct into an array in Coldfusion without looping over it? I know it can be done this way if we use a for in loop:
local.array = [];
for (local.value in local.struct)
{
arrayAppend(local.array, local.value);
}
Does StructKeyArray suit your requirements?
Description
Finds the keys in a ColdFusion
structure.
If you are trying to maintain order in your structure you could always use a Java LinkedHashMap like so:
cfmlLinkedMap = createObject("Java", "java.util.LinkedHashMap").init();
cfmlLinkedMap["a"] = "Apple";
cfmlLinkedMap["b"] = "Banana";
cfmlLinkedMap["c"] = "Carrot";
for(key in cfmlLinkedMap){
writedump(cfmlLinkedMap[key]);
}
You could also do the same thing in a more "java" way not sure why you'd want to but its always an option:
//no need to init
linkedMap = createObject("Java", "java.util.LinkedHashMap");
//java way
linkedMap.put("d","Dragonfruit");
linkedMap.put("e","Eggplant");
linkedMap.put("f","Fig");
//loop through values
iterator = linkedMap.entrySet().iterator();
while(iterator.hasNext()){
writedump(iterator.next().value);
}
//or
//loop through keys
iterator = linkedMap.keySet().iterator();
while(iterator.hasNext()){
writedump(linkedMap.get(iterator.next()));
}
Just remember that the keys are case SeNsItIvE!
In Coldfusion 10 or Railo 4, if you want an array of values (instead of keys), you can use the Underscore.cfc library like so:
_ = new Underscore();// instantiate the library
valueArray = _.toArray({first: 'one', second: 'two'});// returns: ['one','two']
Note: Coldfusion structures are unordered, so you are not guaranteed to have any specific order for the values in the resulting array.
(Disclaimer: I wrote Underscore.cfc)
