Limit the Json response results to top 5 in php

I have a search bar where upon searching i get all the related products, i want to display just top 5 of them
public function getProducts()
{
if (request()->ajax()) {
$search_term = request()->input('term', '');
$location_id = 1;
$check_qty = request()->input('check_qty', false);
$price_group_id = request()->input('price_group', null);
$business_id = request()->session()->get('user.business_id');
$not_for_selling = request()->get('not_for_selling', null);
$price_group_id = request()->input('price_group', '');
$product_types = request()->get('product_types', []);
$search_fields = request()->get('search_fields', ['name', 'sku']);
if (in_array('sku', $search_fields)) {
$search_fields[] = 'sub_sku';
}
$result = $this->productUtil->filterProduct($business_id, $search_term, $location_id, $not_for_selling, $price_group_id, $product_types, $search_fields, $check_qty);
return json_encode($result);
}
}

You can use ->limit(5)->get() to get only 5 product from query
Use orderBy('column_name', 'desc' or 'asc') for sorting the results of the query
You can use laravel standard response json to send back response instead of wrapping inside json_encode
return response()->json($result)

Dynamics CRM 2016 Javascript forEach not supported

So I am trying to write javascript code for a ribbon button in Dynamics CRM 2016 that will grab a phone number from a list of Leads that can be seen in the Active Leads window.
However, when I try to run it, I get an error telling me
As I step into my code (I'm debugging), I see this error
Here is the code I am working with.
function updateSelected(SelectedControlSelectedItemIds, SelectedEntityTypeName) {
// this should iterate through the list
SelectedControlSelectedItemIds.forEach(
function (selected, index) {
//this should get the id and name of the selected lead
getPhoneNumber(selected, SelectedEntityTypeName);
});
}
//I should have the lead ID and Name here, but it is returning null
function getPhoneNumber(id, entityName) {
var query = "telephone1";
Sdk.WebApi.retrieveRecord(id, entityName, query, "",
function (result) {
var telephone1 = result.telephone1;
// I'm trying to capture the number and display it via alert.
alert(telephone1);
},
function (error) {
alert(error);
})
}
Any help is appreciated.

What you have is an javascript error. In js you can only use forEach on an array. SelectedControlSelectedItemIds is an object not an array.
To loop though an object, you can do the following.
for (var key in SelectedControlSelectedItemIds){
if(SelectedControlSelectedItemIds.hasOwnProperty(key)){
getPhoneNumber(SelectedControlSelectedItemIds[key], SelectedEntityTypeName)
}
}

Okay, so I figured it out. I had help, so I refuse to take full credit.
First, I had to download the SDK.WEBAPI.
I then had to add the webAPI to my Javascript Actions in the Ribbon Tool Bench.
Then, I had to create a function to remove the brackets around the
SelectedControlSelectedItemIds
Firstly, I had to use the API WITH the forEach method in order for it to work.
These are the revisions to my code.
function removeBraces(str) {
str = str.replace(/[{}]/g, "");
return str;
}
function updateSelected(SelectedControlSelectedItemIds, SelectedEntityTypeName) {
//alert(SelectedEntityTypeName);
SelectedControlSelectedItemIds.forEach(
function (selected, index) {
getPhoneNumber(removeBraces(selected), SelectedEntityTypeName);
// alert(selected);
});
}
function getPhoneNumber(id, entityName) {
var query = "telephone1";
SDK.WEBAPI.retrieveRecord(id, entityName, query, "",
function (result) {
var telephone1 = result.telephone1;
formatted = telephone1.replace(/[- )(]/g,'');
dialready = "1" + formatted;
withcolon = dialready.replace(/(.{1})/g,"$1:")
number = telephone1;
if (Xrm.Page.context.getUserName() == "Jerry Ryback") {
url = "http://111.222.333.444/cgi-bin/api-send_key";
} else if(Xrm.Page.context.getUserName() == "Frank Jane") {
url = "http://222.333.444.555/cgi-bin/api-send_key";
}
else if( Xrm.Page.context.getUserName() == "Bob Gilfred"){
url = "http://333.444.555.666/cgi-bin/api-send_key";
}
else if( Xrm.Page.context.getUserName() == "Cheryl Bradley"){
url = "http://444.555.666.777/cgi-bin/api-send_key";
}
else if( Xrm.Page.context.getUserName() == "Bill Dunny"){
url = "http://555.666.777.888/cgi-bin/api-send_key";
}
if (url != "") {
var params = "passcode=admin&keys=" + withcolon + "SEND";
var http = new XMLHttpRequest();
http.open("GET", url + "?" + params, true);
http.onreadystatechange = function () {
if (http.readyState == 4 && http.status == 200) {
alert(http.responseText);
}
}
http.send(null);
}
},
function (error) {
// alert(error);
})
}
To elaborate, once I successfully get the number, I remove the parenthesis, dashes and white-space. Then, I add a "1" to the beginning. Finally, I insert colons in between each number. Then, I create an HTTP command and send it to the office phone of whoever is using CRM at the time. The user eval and HTTP message is my code. I'm showing you all of this because it was a great learning experience, and this feature really adds to the functionality.
I hope some of you find this useful.
Thanks for the help.

remember search query to use in function

I'm using Angularjs with the dirPagination plugin to connect with an Web API. This seems to work fine. I added a search function, to do a server side search:
$scope.searchChanged = function () {
if ($scope.searchFor.length == 0) {
$scope.calculatedValue = 'e';
} else {
vm.getData(vm.pageno, vm.getSearch($scope.searchFor));
}
}
vm.getSearch = function (query) {
if (query == undefined) {
query = 'tech';
} else {
query = query;
}
return query;
}
See Plnkr for the full code
If I start searching (e.g. sales) the API returns results and the paging is correct, the get request is:
/api/students/?category=sales&begin=1&pageSize=10
But if you want to go to another page number, the get request to the server is:
/api/students/?category=tech&begin=2&pageSize=10
How can the view remember the query 'sales', so that the paging and results are correct?

You are making a common mistake here: You don't need to pass in variable from the view if you are already using a scope variable.
Changing to this would be much less error prone
// change this to var getSearch or function getSearch if you don't need it on the view anymore
vm.getSearch = function () {
var query = vm.searchFor;
// you should only use vm, change ng-model to data.searchFor
if (query == undefined) {
query = 'tech';
}
return query;
}
vm.getData = function () {
vm.users = [];
$http.get("/api/students/?category=" + vm.getSearch() + "&begin=" + vm.pageno + "&pageSize=" + vm.itemsPerPage).success(function (response) {
vm.users = response.data;
vm.total_count = response.total_count;
});
};

Your request id good, you need to optimize the sql query so you can get the right results. it should look something like this:
#begin INT = 0,
#pageSize INT = 10
SELECT *
FROM [TableName]
ORDER BY id
OFFSET (#pageSize * #begin )
ROWS FETCH NEXT #pageSize ROWS ONLY;

How to know all JSON object has been iterated? [duplicate]

This question already has answers here:
Wait until all jQuery Ajax requests are done?
(22 answers)
Closed 7 years ago.
I m working on phonegap product using jquery and jquery mobile, the scenario is, when user is logging in for first time, we sync all the data and after done we forward user to another view. The items are retrieved in json format from server. Here are the portion of my code. I have called the webservice and the response is returned as JSON objects in response variable.
$(response.data.module.registration).each(function(k,v){
//insert into app's sqlite database
});
$(response.data.module.attendance).each(function(k,v){
//insert into app's sqlite database
});
$(response.data.items.grocery).each(function(k,v){
//insert into app's sqlite database
});
//and so on. There could be many rows in each loop above.
My question is how to know all rows has been inserted from the loop so that I can forward user to restricted area.
more precisely, how to know all JSON object has been iterated successfully?
What i tried is put counter in each loop and check if sum of all the counters is equal to total items we are iterating. But this didn't work the sum of all the counters are readily available before all items are inserted.
EDIT
Here is my helper function that inserts record into sqlite db. This didn't work, user was logged in before all data are inserted. Can you tell me where I went wrong
var sqlhelper = {
insertJSONData:function(tablename,data,callback){
var dfrd = $.Deferred();
var fields=sqlhelper.separateFieldData(data,"field");
var dataval=sqlhelper.separateFieldData(data,"value");
sqlhelper.db.transaction(function(tx) {
var sqlquery='INSERT INTO '+tablename+' ('+fields+') values('+dataval+')';
console.log(sqlquery);
tx.executeSql(sqlquery,[],function(tx,result){
dfrd.resolve(result);
console.log('Success');
},sqlhelper.errorCB);
if(callback!=undefined){
callback();
}
});
return dfrd.promise();
}
}
And here is the code that fetches server response
function defObj1()
{
if(typeof response.data.module.registration!="undefined"){
$(response.data.module.registration).each(function(i,e){
var data = {
'reg_id': e.reg_id,
'reg_name': e.reg_name,
'reg_desc': e.reg_desc,
'reg_status': e.reg_status
};
sqlhelper.insertJSONData('tbl_registration',data);
}); // end of each loop
}
}
function defObj2()
{
if(typeof response.data.items.grocery!="undefined"){
$(response.data.items.grocery).each(function(i,e){
var data = {
'grocery_id': e.grocery_id,
'item_name': e.item_name,
'item_qty': e.item_qty,
'item_unit_price': e.item_unit_price
};
sqlhelper.insertJSONData('tbl_grocery',data);
}); // end of each loop
}
}
$.when(defObj1() ,defObj2()).done(function(a1,a2){
//sync complete so login user
doLogin();
})
Thanks

try this. (Edited)
var isValid = true, i = 0, sum, callback = function () {
//if all inserting is successfully it is called
};
...
$(response.data.module.registration).each(function (k, v) {
//insert into app's sqlite database
var data = {
'reg_id': e.reg_id,
'reg_name': e.reg_name,
'reg_desc': e.reg_desc,
'reg_status': e.reg_status
};
sqlhelper.insertJSONData('tbl_registration', data, function (data) {
if (!data) {
isValid = false;
sum++;
}
i++;//onSuccess function
checkLast(i);//call this lastly method or each
}, function () {
i++;//onError function
});
});
...
//other codes is identical logic
...
function checkLast(i) {
if (i == sum) {
callback();
}
}
...
I have added successCallbak and errorCallback to your sqlhelper
var sqlhelper = {
insertJSONData: function (tablename, data, successCallbak, errorCallback) {
var dfrd = $.Deferred();
var fields = sqlhelper.separateFieldData(data, "field");
var dataval = sqlhelper.separateFieldData(data, "value");
sqlhelper.db.transaction(function (tx) {
var sqlquery = 'INSERT INTO ' + tablename + ' (' + fields + ') values(' + dataval + ')';
console.log(sqlquery);
tx.executeSql(sqlquery, [], function (tx, result) {
dfrd.resolve(result);
if (successCallback) {
successCallback(result);
}
console.log('Success');
}, sqlhelper.errorCB);
if (errorCallback) {
errorCallback();
}
});
return dfrd.promise();
}
}

Access js array in another js file

I fill my array in the checklistRequest.js and I want to access it in my Termine_1s.html file which contains js code. I can access it but when I want to iterate through it, it gives me only single digits instead of the strings.
How can I solve this?
checklistRequest.js
//Calls the checkbox values
function alertFunction()
{
//Retrieve the object from storage
var retrievedObject = localStorage.getItem('checkboxArray');
console.log('retrievedObject: ', JSON.parse(retrievedObject));
return retrievedObject;
}
Termine_1s.html
//Checks if title was checked already
var checklistRequest = alertFunction();
var titleAccepted = true;
for (var a = 0; a < checklistRequest.length; a++)//Iterates through whole array
{
if(title != checklistRequest[i] && titleAccepted == true)//Stops if false
{
titleAccepted = true;
}
else
{
titleAccepted = false;
}
}

you need to parse the object at some point.
Try:
return JSON.parse(retrievedObject);
