[If you want to add any feature in your site, then keep backup file of themes of site]
WordPress Short Feature:
15 WordPress feature, definitely work for New Comers.
#1. Visitor Count Systems/ Feature:
Generally, many people use Post-Views plugin to know how many visitors have read our post, there are some small work for which it is better not to use the plugin.
For this, today we will do WordPress blog / system of counting post view of the site, writing some code line.
Steps: At first go to wp-admin option and then go to appearance menu and then go to editor option and then go to
functions.php
From template files.
Select that file.
Now write this code in below.
function getPostViews($postID){
$count_key = 'post_views_count';
$count = get_post_meta($postID, $count_key, true);
if($count==''){
delete_post_meta($postID, $count_key);
add_post_meta($postID, $count_key, '0');
return "0 View";
}
return $count.' Views';
}
function setPostViews($postID) {
$count_key = 'post_views_count';
$count = get_post_meta($postID, $count_key, true);
if($count==''){
$count = 0;
delete_post_meta($postID, $count_key);
add_post_meta($postID, $count_key, '0');
}else{
$count++;
update_post_meta($postID, $count_key, $count);
}
}
[Remember, you will write surely after <?php and before ?>Â
Step2: Now open
single.php
From the template file and write code in below.
1 <?php setPostViews(get_the_ID()); ?>
Step3: Now you want to show post view counter in which location, write code in below there.
1 <?php echo getPostViews(get_the_ID()); ?>
[Generally, many people use post beside title, date so, you have to set surely in
single.php
]
#2. In which way you will give permission to upload photo of WordPress blog/contributors of site.
At first, open
functions.php
Of themes in any editor.
Notepad/notepad++ or WordPress are in the dashboard.
Write code in below.
<?php
//allow contributor to add photos
if ( current_user_can('contributor') && !current_user_can('upload_files') ) {
add_action('admin_init', 'allow_contributor_uploads');
function allow_contributor_uploads() {

You can do this.
