[FIXED] How to check if a number has a whatsapp account?

Issue

We have configured the WhatsApp cloud API (not as a BSP). We use a messages endpoint to send messages to our customers. But we need to validate if the customer number has a WhatsApp account associated with it.

Is there any endpoint available to check if a number has a WhatsApp account? Kindly Help.

Solution

There is an option in On-premises API using contacts API but there is no option for Cloud API.

Hope they will provide in the future.

[FIXED] What is the wp_postmeta table

Issue

From my understanding, the wp_postmeta extends the schema for wp_post. So basically the standard fields/structure for a post will be found in wp_posts, and if any post(s) needed their own set of fields/attributes etc, they would be defined in wp_postmeta table. So I wanted to know if I'm right about this or not?

thanks.

Solution

You are absolutely right. If there exist some meta box or "own set of fields/attributes" wp_postmeta table will store those field's values.

[FIXED] How to load User Meta?

Issue

Wordpress author.php is not loading the correct information from user meta. It's loading whoever is currently logged in to the blog and not displaying the person who it links to for example:

http://www.website.com/author/username1
http://www.website.com/author/username2

is displaying the same despite been two different users. I've done what is asked, however I'm still confused to why its only loading the currently user meta and not the meta of the username?

This is my author template:

<?php get_header(); ?>  

<div class="author-name">
<?php echo get_the_author_meta('first_name'); ?>
<?php echo get_the_author_meta('last_name'); ?> 
<?php echo get_user_role('user_role'); ?>
</div>

<div class="author-information">
Username: <?php echo get_the_author('user_nicename'); ?>
</div>

<?php get_footer(); ?>  

Solution

You must supply the User ID when using get_the_author_meta() to get a different user than the one in the loop or currently logged in.

Assuming username1 and username2 are actual usernames in the users database table you can get the username from the URL by using the following snippet:

$username_from_url = basename( get_permalink() );

And then:

$user = get_user_by( 'login', $username_from_url );

Now you have the full $user object with ID and everything.

Edit: complete solution

User visits an URL with the following pattern /page/somename where somename corresponds to the user´s user_nicename in the database table users.

<?php
    $username_from_url = basename( get_permalink() );
    $user = get_user_by( 'slug', $username_from_url );

    echo get_the_author_meta( 'first_name', $user->ID );
    echo get_the_author_meta( 'last_name', $user->ID );

    foreach ($user->roles as $role) {
        // You can also use get_role( $role ) to get more data on the role
        echo $role;
    }

    echo __( "Username:" ) . " " . $user->user_nicename;
?>

[FIXED] How do you combine multiple (different) images into a single favicon?

Issue

There are lots of services that will take an image and create every size of web icon out of it by downscaling it to the appropriate resolutions.

However, I have designed two favicons specifically for their resolution (16x16 and 32x32), which means I have two separate, different pngs. I would love to combine these icons into one favicon.ico so I can serve that file properly. Anyone know how one could accomplish this?

Solution

You can use ImageMagick:

# For Ubuntu
sudo apt-get install imagemagick

convert favicon.ico favicon.png

# Now you have several files named favicon-0.png, favicon-1.png...
# Edit them or replace them

# Merge the PNGs into a single ICO
# Of course, list all the PNGs you need to merge
convert favicon-0.png favicon-1.png new_favicon.ico

Icotool (sudo apt-get install icoutils) works in a similar way. Beware, it produces larger ICO when the embedded PNGs are large (which is usually not the case).

Microsoft development tools (think Visual Studio) probably come with ICO edition tools, but I'm not in this stuff.
