How to add custom logo in wordpress theme

The WordPress theme customizer is famous for being able to change your theme colors in real time, but did you know it can handle almost any type of theme option?
You can add layout options, image uploaders, text fields, and lots more. The possibilities are endless!
There is almost no need for theme options pages anymore. I personally like the idea of having no theme options page, and limiting everything to the theme customizer.
I’m going to show you how to add a custom logo uploader to your theme customizer, then display it in place of the site title and tagline.

Create the logo uploader setting

This may be review for some of you, but I’ll go over my basic setup for using the theme customizer. In my custom theme folder most of the code is going into /inc/customizer.php, and then we will include that file via functions.php. You could put all the code into functions.php and it will work, but it’s nice to keep functions.php uncluttered.
First, we create our function to register the new settings. I’ve prefixed my function name with m1, but you can use whatever you want:

function m1_customize_register( $wp_customize ) {

    // All the code in this tutorial goes here

}

add_action( 'customize_register', 'm1_customize_register' );

Inside our function we need to register a setting. This saves the logo url in the database so we can use it in our theme.

function m1_customize_register( $wp_customize ) {

    $wp_customize->add_setting( 'm1_logo' ); // Add setting for logo uploader

}

add_action( 'customize_register', 'm1_customize_register' );

Next, we add the uploader and assign it to a section. You could create a new section, but I think it goes nicely with the title and tagline. If you are using a different name for your setting, make sure you change all instances of m1_logo to something else.

function m1_customize_register( $wp_customize ) {

    $wp_customize->add_setting( 'm1_logo' ); // Add setting for logo uploader

         

    // Add control for logo uploader (actual uploader)

    $wp_customize->add_control( new WP_Customize_Image_Control( $wp_customize, 'm1_logo', array(

        'label'    => __( 'Upload Logo (replaces text)', 'm1' ),

        'section'  => 'title_tagline',

        'settings' => 'm1_logo',

    ) ) );

}

add_action( 'customize_register', 'm1_customize_register' );

That’s it for the code in customizer.php. To make sure our theme uses this file, simply add this one line of code in functions.php:

require get_template_directory() . '/inc/customizer.php';

That’s it! We kept our functions.php file clean as a whistle.
Next we need to display our logo.

Displaying the logo

We are going to work in our theme’s header.php file to display the logo. If there is no logo, we’ll just display the site title and description.
To get the logo url from our theme customizer, you use this code:

get_theme_mod( 'm1_logo' )

You can store that in a variable if you want, or echo it out as is. Since we are only using this value once in our theme, we don’t need to store it in a variable.
Wherever your site title is displayed in header.php, you’ll want to replace it with this code:

<?php if ( get_theme_mod( 'm1_logo' ) ) : ?>

    <a href="<?php echo esc_url( home_url( '/' ) ); ?>" id="site-logo" title="<?php echo esc_attr( get_bloginfo( 'name', 'display' ) ); ?>" rel="home">

        <img src="<?php echo get_theme_mod( 'm1_logo' ); ?>" alt="<?php echo esc_attr( get_bloginfo( 'name', 'display' ) ); ?>">

    </a>

    <?php else : ?>

               

    <hgroup>

        <h1 class="site-title"><a href="<?php echo esc_url( home_url( '/' ) ); ?>" title="<?php echo esc_attr( get_bloginfo( 'name', 'display' ) ); ?>" rel="home"><?php bloginfo( 'name' ); ?></a></h1>

        <p class="site-description"><?php bloginfo( 'description' ); ?></p>

    </hgroup>

               

<?php endif; ?>

So let’s talk through that chunk of code. First, we create an if statement that says, “if a theme logo has been uploaded, display this logo code. Otherwise, display the site title and site description.”
The logo is linked to the homepage, it has some alt text, blah blah blah. The important part is this:

src="<?php echo get_theme_mod( 'm1_logo' ); ?>"

Make sure to tell the user a recommended logo size, otherwise they can upload a huge file that doesn’t fit quite right. You might also want to give the container around the logo a constrained width, so it will fit no matter what.

How to disable admin bar in wordpress

Set the display status of the Toolbar for the front side of your website (you cannot turn off the toolbar on the WordPress dashboard).
Placing the above line of code in theme's function.php file will prevent the Toolbar from rendering on the front end of your site.
You can also determine for which users the admin bar is shown. For example the following lines will only display the admin bar for users with administrative privileges.

if ( ! current_user_can( 'manage_options' ) ) {
    show_admin_bar( false );
}

With newer version of WordPress you may need to use the following which 
will leave the Toolbar available in the Dashboard but hide it on all 
front facing pages. 

add_filter('show_admin_bar', '__return_false'); 

how to disable comments in wordpress

Settings >> Discussion >> uncheck "Allow people to post comments on new articles"
This applies to new posts that you will publish from now on. To disallow comments from already publish posts:
Posts >> select them all and "Edit" under bulk actions and hit apply >> choose "do not allow" next to comments and hit update posts. and other way

The topic title talks about "pages". Assuming that you want to continue have discussion on your blog posts but turn it off only from "pages, you'll have to remove the code snippet "<?php comments_template(); ?>" from the page.php of your theme, as mercime advised.

How to turn off wordpress update notification

For all the WordPress users, it is really annoying when WordPress update notice is displayed on the dashboard if there are any upgrade available for the installed WordPress version as shown in the figure below. The notice will not clear until the WordPress is upgraded to latest version. Similarly the update notice for installed plugins & themes is displayed on the WordPress dashboard, plugins & themes pages. Actually it is good to know that updates are available but administrators who maintain multiple installations of WordPress on behalf of other people (eg. clients) may not want theme update notifications to be shown to the users of these installations, then disabling such notifications becomes necessary. In this article, I will show how to disable update notifications for core WordPress as well as for plugins and themes.

1. To Disable Update WordPress nag :

Insert the following code to the functions.php file of your active theme. It will remove the WordPress update nag e.g. WordPress 3.9.1 is available! Please update now, from the all users dashboard, admin dashboard & from Updates page as well.

add_action('after_setup_theme','remove_core_updates');
function remove_core_updates()
{
 if(! current_user_can('update_core')){return;}
 add_action('init', create_function('$a',"remove_action( 'init', 'wp_version_check' );"),2);
 add_filter('pre_option_update_core','__return_null');
 add_filter('pre_site_transient_update_core','__return_null');
}

2. To Disable Plugin Update Notifications :

Insert the following code to the functions.php file of your active theme. It will remove the update notifications of all the installed plugins.

remove_action('load-update-core.php','wp_update_plugins');
add_filter('pre_site_transient_update_plugins','__return_null');

3. To Disable all the Nags & Notifications :

Insert the following code the functions.php file of your active theme. This code disables all the updates notifications regarding plugins, themes & WordPress completely.

function remove_core_updates(){
global $wp_version;return(object) array('last_checked'=> time(),'version_checked'=> $wp_version,);
}
add_filter('pre_site_transient_update_core','remove_core_updates');
add_filter('pre_site_transient_update_plugins','remove_core_updates');
add_filter('pre_site_transient_update_themes','remove_core_updates');

Apart form these codes there are some WordPress plugins available to Disable WordPress Update Notifications & Nags :
If you install & activate these plugins, you will have to keep yourself updated with the latest version of your active WordPress, plugins & themes so that your blog or website wont be susceptible to security vulnerabilities or performance issues. Just deactivate the plugin for short period of time & update yourself.

how to change woocommerce language?

WooCommerce comes localization ready out of the box – all that’s needed is your translation, if the plugin does not come bundled with one for your language.
There are several methods to create a translation, most of which are outlined in the WordPress Codex. However, we find the easiest method is to use a plugin called Loco Translate. More advanced users can use PoEdit. Both methods are covered in this doc.

Before you begin 

WooCommerce includes a language file (.po or .pot file) which contains all of the English text. You can find this language file inside the plugin folder in woocommerce/i18n/languages/.

Set up WordPress

WordPress needs to be told which language it should run under.

1. Go to: Dashboard > Settings > General and change the Site language.

Once this has been done, the shop will be displayed in your locale if the language file exists. Otherwise you need to create the language files (process explained below).

WooCommerce 2.2+ Language Packs 

From version 2.2, WooCommerce includes a language pack downloader. PO and MO files will no longer be bundled with the plugin – they will be downloadable from your dashboard if you have the WPLANG constant set, or from a git repository if you wish to grab them manually. A notice will be displayed within your administration:

Update WooCommerce 2.2+ Translation Packs

If for some reason the translation packs install fails, you can force the download in WooCommerce > System Status > Tools > Force Translation Upgrade:

Force Translation Upgrade (WooCommerce > System Status > Tools)

PO and MO files are copied in wp-content/languages/woocommerce/

How to re-order the product tabs?

Change it as you want it and add to the functions.php, but here is a snippet to put the reviews first, description second and additional info third:

add_filter( 'woocommerce_product_tabs', 'woo_reorder_tabs', 98 );


function woo_reorder_tabs( $tabs ) {


 


 


$tabs['reviews']['priority'] = 5; // Reviews first


$tabs['description']['priority'] = 10; // Description second


$tabs['additional_information']['priority'] = 15; // Additional information third


 


 


return $tabs;


}
