How to add google fonts to wordpress

  • Find right font

Access google fonts @ https://fonts.google.com/. You can browse or search to find the required font at this website.

  • Select the customisation as per your requirements.

Lets suppose you selected a font called “Crimson Text”. Click on “select this font” and it will open following window. please select the customisation required.

This will create a url, copy this url

 

  • Enqueueing google fonts in wordpress

Use the url copied in previous step and copy in into functions file with following code.

As you can see in below code, multiple fonts can be copied as below. In below function “Poppins” and “Crimson” is copied

function startwordpress_google_fonts() {
wp_register_style('Poppins', 'https://fonts.googleapis.com/css?family=Poppins:300,400,500,600,700');
wp_enqueue_style( 'Poppins');
wp_register_style('Crimson', 'https://fonts.googleapis.com/css?family=Crimson+Text:400,400i,600,600i,700');
wp_enqueue_style( 'Crimson'); 
}

add_action('wp_print_styles', 'startwordpress_google_fonts');

 

And you are all set. You can use this font in your world press CSS with the name that you have provided while registering this font. Normally you the same name while registering the font name to avoid the confusion.

Getting started with laravel with Ubuntu 16.04

Laravel is a flexible and lightweight open source PHP framework with Model-View Controller (MVC) design pattern. Laravel makes application development very fast and you can make highly scalable application development using Laravel.

Before installing Laravel you need to install composer

Install composer
php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"  
php -r "if (hash_file('SHA384', 'composer-setup.php') === '544e09ee996cdf60ece3804abc52599c22b1f40f4323403c44d44fdfdd586475ca9813a858088ffbc1f233e9b180f061') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"  
php composer-setup.php  
php -r "unlink('composer-setup.php');"  

This will install it locally. Now move it to path folder

$mv composer.phar /usr/local/bin/composer
Install Laravel

You can download Laravel using composer as below.

$ composer global require "laravel/installer=~1.1"

Once installation is completed you can create a new app using following command.

$laravel new firstapp

While creating an app, I got following error.

$laravel new firstapp

To get rid of this error, you need to install php7.0. You can install it using following command.

$sudo apt-get install php7.0-zip 

Once php7.0 is installed, previous error got resolved but I got another error

To get ride of latest errors, you can install following two packages.

$sudo apt-get install php-mbstring 
$sudo apt-get install php-xml

After installation of above two packages I got another errors.

Getting started with PHP

Your PHP code goes inside the

<?php  
code here  
?>

To display text in HTML output page

echo "this is output";  

Make sure to end your line of PHP code with a semicolon

;
String Manipulations
<?php  
$name = "Luke Perry";
echo strlen($name); // 10  
echo substr($name, 0, 3); // Luk  
echo strtoupper($name); // LUKE PERRY  
echo strpos($name, "e Perry"); // 3  
// concatenation
echo "hello" . "user";  
?>
Variables

All variable names in PHP start with a dollar sign

$temp
Comment

comment is started with either of following code

//

or

#
Operators
> Greater than
< Less than  
<= Less than or equal to  
>= Greater than or equal to
== Equal to
!= Not equal to
Conditional Sentence
    if ( 2 > 10) {
        echo " ok";
        }
    else if ( 2 == 33 ) {
        echo "ccc";
        }
    else if ( 3 == 34) {
        echo "this is 3";
    }
    else {
        echo "nothing mathcn";
        }
switch
    switch (2) {
        case 0:
            echo 'The value is 0';
            break;
        case 1:
            echo 'The value is 1';
            break;
        case 2:
            echo 'The value is 2';
            break;
        default:
            echo "The value isn't 0, 1 or 2";
    }

Using or clause with switch

    switch ($i) {
        case 0:
            echo '$i is 0.';
            break;
        case 1:
        case 2:
        case 3:
        case 4:
        case 5:
            echo '$i is somewhere between 1 and 5.';
            break;
        case 6:
        case 7:
            echo '$i is either 6 or 7.';
            break;
        default:
            echo "I don't know how much $i is.";
    }
Working with Array

defining array and adding new element

      <?php
        // Add your array elements after
        // "Beans" and before the final ")"
        $array = array("Egg", "Tomato", "Beans" );        
      ?>
<?php  
$states = array();
$array = array_push($states, "Montana");
$array = array_push($states, "North Carolina");
$array = array_push($states, "California");
echo $array; // returns 3  
var_dump($states);  
?>

Pushing multiple elements together

<?php  
$states = array(); // target array
$array = array_push($states, 
"Montana", 
"North Carolina", 
"California");
echo $array; // returns 3  
var_dump($games);  
?>

Print array

<?php  
echo $tens[2];  
echo $tens{2};  
?>

Modify and delete array element

$languages[1] = "green";
unset($array[2]);  
unset($array);  
Loop
        foreach($languages as $lang) {
          print "<p>$lang</p>";
        }

another example

      <?php
        // Echoes the first five even numbers
        for ($i = 2; $i < 11; $i = $i + 2) {
          echo $i;
        }
      ?>
