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
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”
app/foldername
"autoload": {
"classmap": [
"app/commands",
"app/controllers",
"app/models",
"app/database/migrations",
"app/database/seeds",
"app/tests/TestCase.php",
"app/Libraries",// we've added classes folder on compose
]
},
And we can update composer by using below comment
composer dump
Now we can use our helper class in our controller
$test = new className();
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();
}
}
compser file
"autoload": {
"classmap": [
"app/commands",
"app/controllers",
"app/models",
"app/database/migrations",
"app/database/seeds",
"app/tests/TestCase.php",
"app/Libraries",// we've added classes folder on Laravel ClassLoader
]
},

Today I want to create a page for sending contact us mail in site,
For that I have to define admin mail id and admin name as a config value and i want to access the same in same in many places,
I had googled for some time , to find out how can i define my constant in laravel and one of my friend (Ranjith) help to do that ,
Here i am writing how we can use a Config values in laravel,
1. If we want to define all our constants in a custom page ,
We can create a page (Here i am calling constants.php )
and inside that we can define like key value pair
return array( 'custome_name' =>'custome_value', )
And we call the values as below
$cvalue = Config::get('filename.custome_name');
Here we will get our custom_value in $cvalue
Let us look an example
<?php
return array(
'admin_email' =>'mail@shabeebk.com',
'admin_name' =>'Admin',
);
?>
Now let us see How we can retrieve the config in your code somewhere
echo Config::get('constants.admin_email');
echo Config::get('constants.admin_name')
Hope it will help some one 🙂
Thank you Ranjith
I made small changes,
thank you Martin Tonev for correcting from variable to config

Today i was trying to install laravel in MAMP , While going through their step on laravel site mentioned i found that i didn installed mycript extension. I had googled for lot of time and lastly i installed .
I am writing this will help some one to install laravel in Mac using MAMP.
Before installing laravel we have to install composer . We can go to https://getcomposer.org/ and we can install from from there or we can follow the following steps step
1. first we have to check curl is enabled . step 2. we can install composer globally as mentioned in their site
curl -sS https://getcomposer.org/installer | php mv composer.phar /usr/local/bin/composer
1.once we installed composer we have to move to htdocs and to our directory from our terminal
cd /directory/folder
2. We can tell composer to download laravel and install by following commands
composer global require "laravel/installer=~1.1"
composer create-project laravel/laravel your-project-name --prefer-dist
And here it will come to as for mycrypt extension .
Mcrypt PHP extension required.
To solve this issue we have to check the php version frist
php -v
3.Now let us have our PHP version, in my case 5.6.2, we can open our .bash_profile script
nano .bash_profile
4. Add our MAMP PHP version after the code already present ,Exit the file and Save it.
export MAMP_PHP=/Applications/MAMP/bin/php/php5.5.10/bin export PATH="$MAMP_PHP:$PATH"
5. Now we can try to install Laravel again That is it!.
composer create-project laravel/laravel your-project-name --prefer-dist
6. We can see Laravel is downloading and installing
Finally it will show like installed. Application key (*******) installed successfully.
Now let us go to browser and check the URL.
That is it!

The jquery scrolltop () method gets the top offset of the first matched element.
Let us have a look,
If we want to know vertical scroll postion of current window we can use,
scroll_leng= $(window).scrollTop();
It will return the vertical scrollbar position of corresponding to window.
like the same we can set the vertical scrollbar position of window into some postion as below
$(window).scrollTop(position);
If we want to know vertical scroll postion of a perticular element window we can use,
scroll_leng= $(selector).scrollTop();
It will return the vertical scrollbar position of particular element.
like the same we can set the vertical scrollbar position of particular element into some postion as below
$(selector).scrollTop(position);
Sometime we have to give animation also , it is simple by using animate function in jquery
$(selector).animate({scrollTop: scroll_value}, delay);
sample demo below:

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.
First we can write Regex as below,
^(((.*\d.*[A-Z].*[!@#$%^&*? ~].*))|(.*[A-Z].*\d.*[!@#$%^&*? ~].*)|(.*[!@#$%^&*? ~].*[A-Z].*\d.*)|(.*[!@#$%^&*? ~].*\d.*[A-Z].*))$
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.
Let us look on the demo
Let us look a jquery demo
You can download from github

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.
$('.integer-allowed').keyup(function () {
this.value = this.value.replace(/[^0-9\.]/g, '');
});
Working demo
Enter value (Numbers only allowed)
Working code
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>

We can remove tracking of git for some file using below comment .
git update-index --assume-unchanged <file full path>
To track the file again we can use below comment
git update-index --no-assume-unchanged <file full path>
Now let us look How we can list all the files who is included in no-assume
We can type below comment in terminal
git ls-files -v
It will list like
H file 1 H file 2 h file 3 h file 4
Here we can see first character as capital or lower for some file.
If the first character is lowercase, it is marked as “assume unchanged”, else it is marked as “assume changed”
We can simply list all the “assume unchanged”files using below comment.
git ls-files -v | egrep -r "^h .*"
it will list only “assume unchanged” file list
Example
h file 3 h file 4
