6 Best WordPress Code Snippets Plugins for Customization

02Mar 2023 by Moonthemes 2705 Comments

WordPress is an excellent website platform that works great straight out of the box. However, you may sometimes want to add customizations of your own. One way you can modify your WordPress site without installing lots of plugins is to use code snippets. A code snippets plugin is the best way to add code snippets.

Yes, I know that sounds like a contradiction – installing a plugin so you don’t have to use plugins. But one code snippet plugin can replace several other plugins, thus reducing the overall number of plugins required.

What Are Code Snippets?

Code snippets are small segments of code that can be easily integrated into a website or application. They make it possible to add functionality or modify existing features with ease. 

Code snippets play a significant role in the development process, from customizing a site’s appearance to adding new features not included in the default installation.

In WordPress, code snippets can be added using a plugin or editing the theme’s functions.php file. This provides developers with a wide range of options for customizing their sites. Using code snippets, a developer can quickly and easily add new functionality to their site without writing complex code from scratch.

7 Useful Code Snippets Examples

Code snippets can be used in many ways. Here are some examples.

NOTE:

Before making any changes to your website, back it up. Also, I cannot be held responsible if the following code harms your website.

Protect your website from attacks

Add this code to your functions.php file to reject malicious URL requests:

global $user_ID; if($user_ID) 
    if(!current_user_can('administrator'))

If you do not need the search feature on your WordPress site, you can remove it entirely with this code snippet. The custom function nullifies the search feature, including the search bar in your sidebar and menu. This can be helpful if you have a low-spec server and your site does not require searching. To implement this, add the code to the functions.php file.

function fb_filter_query( $query, $error = true ) 
if ( is_search() ) 
$query->is_search = false;
$query->query_vars[s] = false;
$query->query[s] = false;
// to error
if ( $error == true )
$query->is_404 = true;


add_action( 'parse_query', 'fb_filter_query' );
add_filter( 'get_search_form', create_function( '$a', "return null;" ) );

Let contributors upload images

By default, WordPress restricts contributor accounts from uploading images. To allow contributors to upload images without granting additional rights, add the following PHP code snippet to your functions.php file:

if ( current_user_can('contributor') && !current_user_can('upload_files') )
     add_action('admin_init', 'allow_contributor_uploads');      
     function allow_contributor_uploads() 
          $contributor = get_role('contributor');
          $contributor->add_cap('upload_files');

Hide the WordPress admin bar

The WordPress Admin Bar is a useful feature that provides quick access to key functions, such as adding new posts and pages. However, if you don’t need it and want to remove it, you can do so by pasting this code snippet into your functions.php file:

// Remove the admin bar from the front end
add_filter( 'show_admin_bar', '__return_false' );

Display popular posts

It can be useful to display your most popular posts. If any of your readers liked a certain bunch of your posts, new visitors might appreciate seeing them too. To achieve this, add this PHP code to functions.php:

function count_post_visits() 
    if( is_single() ) 
        global $post;
        $views = get_post_meta( $post->ID, 'my_post_viewed', true );
        if( $views == '' ) 
            update_post_meta( $post->ID, 'my_post_viewed', '1' );   
         else 
            $views_no = intval( $views );
            update_post_meta( $post->ID, 'my_post_viewed', ++$views_no );
        
    

add_action( 'wp_head', 'count_post_visits' );

Afterward, you can insert the following code wherever you wish to display the popular posts in your template files:

$popular_posts_args = array(
    'posts_per_page' => 3,
    'meta_key' => 'my_post_viewed',
    'orderby' => 'meta_value_num',
    'order'=> 'DESC'
);
$popular_posts_loop = new WP_Query( $popular_posts_args );
  while( $popular_posts_loop->have_posts() ):
    $popular_posts_loop->the_post();
    // Loop continues
endwhile;
wp_reset_query();

Paginate your website

Good pagination is a useful way for users to browse a website. Instead of using “previous” and “next” links, pagination can be added to your content using a code snippet in the functions.php file of your WordPress theme.

global $wp_query;
$total = $wp_query->max_num_pages;
// only bother with the rest if we have more than 1 page!
if ( $total > 1 ) 
     // get the current page
     if ( !$current_page = get_query_var('paged') )
          $current_page = 1;
     // structure of "format" depends on whether we're using pretty permalinks
     $format = empty( get_option('permalink_structure') ) ? '&page=%#%' : 'page/%#%/';
     echo paginate_links(array(
          'base' => get_pagenum_link(1) . '%_%',
          'format' => $format,
          'current' => $current_page,
          'total' => $total,
          'mid_size' => 4,
          'type' => 'list'
     ));

Create shortcode for PayPal donation

You can use a code snippet to create a shortcode to make it easier for your website’s visitors to donate using the PayPal Donate function. To do this, simply insert the following code in the functions.php file:

function donate_shortcode( $atts, $content = null) 
global $post;extract(shortcode_atts(array(
'account' => 'your-paypal-email-address',
'for' => $post->post_title,
'onHover' => '',
), $atts));
if(empty($content)) $content="Make A Donation";
return '<a href="<https://www.paypal.com/cgi-bin/webscr?cmd=_xclick&business=".$account."&item_name=Donation> for '.$for.'" title="'.$onHover.'">'.$content.'</a>';

add_shortcode('donate', 'donate_shortcode');

Then you can place the [donate] shortcode anywhere on your website, like this: [donate]Your Text[/donate].
