Now, let’s add fields in our settings page to store our Facebook and Twitter profile URLs.

Here’s the code to add input text fields using the Settings API.

input-fields-social

After the admin panel is initialized, we’re registering the sections and fields display callbacks. Here we’re using three important functions:

  1. add_settings_section is used to display the section heading and description.
  2. add_settings_field is used to display the HTML code of the fields.
  3. register_setting is called to automate saving the values of the fields.

 

Here’s what our settings page should now look like.

Uploading a Logo

Here is code to upload a logo in our settings page.

Put this code in the callback function of menu page i.e. theme_option_page_callback()

Again this will only show a submit button.

register-logo

Now Make a functions for the HTML fields.

display uploal field1
display upload field2

The register_setting function takes a third argument which is a callback, this callback is fired before it saves the settings into the database. We can utiliz this callback to handle uploads.

callback-upload

Here’s how our settings page looks now.

Retrieving Settings

A theme needs to retrieve the setting values on the front end. The Settings API internally stores the values using the Options API. Therefore, you can retrieve the values using get_option() function.

It’s quite simple, here’s the code.

retrive-social

Here is the code to display logo in frontend.
