Sometime we have to request files from different host using ajax, and it may create problem because of CORS polices.
CORS means Cross-Origin Resource Sharing (CORS).
Cross domain request will be block by most of the browsers due to same-origin security policy. so we have to enable CORS on our server.we can do this by setting Access-Control-Allow-Origin in a PHP with changing server.
if we need to allow a request from a perticular domain we can restrict as below
In most case, we want to extend our Laravel applications capabilities by adding helper class.
It is not a best practice to insert this classess inside Controller and Model.
so we have to write our classess in separate files and group it by folder
Here let us have a look how we add helper classess in laravel
1. We have app folder on root folder of laravel.There we can create a Libraries folder inside app folder.
2. We can create a class/helper file and we can write a our custom class there, on the top of custom class we have to define namespace our_folder_name;
namespace our_folder_name
for example ,
//here my folder name is Libraries
namespace Libraries;
class className{
//class methodes
}
Now we can go to our controller and on top we can include our helper class
use Libraries\filename as filename;
And we can go to compser, inside autoloder we can add “app/foldername”
All my samples files are given below
Library/className.php
<?php
namespace Libraries;
class className{
//class methodes
function testmesthode(){
return "Hello world";
}
}
testController.php
<?php
use Libraries\className as className;
class testController extends BaseController {
function index(){
$test = new className();
echo $test->testmesthode();
}
}

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry’s standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

Here we are going to write a regular exprestion for Password to check the condition like , password must contain at least one number,one capital letter and one special character.
This will check the string contain at at least one number,one capital letter and one special character,
Here i am going to show examples with Javascript function ,
We can write a function in javascript as below
function validatePassword(str)
{
// patter to match : Atleast one number ,one capital letter, one special charector
var reg = /^(((.*\d.*[A-Z].*[!@#$%^&amp;*? ~].*))|(.*[A-Z].*\d.*[!@#$%^&amp;*? ~].*)|(.*[!@#$%^&amp;*? ~].*[A-Z].*\d.*)|(.*[!@#$%^&amp;*? ~].*\d.*[A-Z].*))$/;
if (reg.test(str)) {
return true;
}
else {
return false;
}
}
and we can pass the string as function argument “str”, It will return if it matches the condition else it will return false.
To allow integer only in text field we can use the following jquery function .
We can write below code inside a document.ready function and give the class “integer-allowed” for the text box we needed.
