How to get input text from theme options on wordpress? - php

Question

I just set up a new input text option into my theme-options.php file, which is similar to the twenty eleven theme code.
Here are parts of my theme-options.php code in regards to the input, I'm looking for a way to get the input that users enter into the 'fact' text and show it on the index.php page:
function themename_theme_options_init() {
register_setting(
'themename_options', // Options group, see settings_fields() call in themename_theme_options_render_page()
'themename_theme_options', // Database option, see themename_get_theme_options()
'themename_theme_options_validate' // The sanitization callback, see themename_theme_options_validate()
);
// Register our settings field group
add_settings_section(
'general', // Unique identifier for the settings section
'', // Section title (we don't want one)
'__return_false', // Section callback (we don't want anything)
'theme_options' // Menu slug, used to uniquely identify the page; see themename_theme_options_add_page()
);
// Register our individual settings fields
add_settings_field( 'facts', __( 'Facts', 'themename' ), 'themename_settings_field_facts', 'theme_options', 'general' );
add_settings_field( 'link_color', __( 'Link Color', 'themename' ), 'themename_settings_field_link_color', 'theme_options', 'general' );
}
add_action( 'admin_init', 'themename_theme_options_init' );
Returns the default facts for Theme Name, based on color scheme:
function themename_get_default_facts( $color_scheme = null ) {
if ( null === $color_scheme ) {
$options = themename_get_theme_options();
$color_scheme = $options['color_scheme'];
}
$color_schemes = themename_color_schemes();
if ( ! isset( $color_schemes[ $color_scheme ] ) )
return false;
return $color_schemes[ $color_scheme ]['default_facts'];
}
Renders the Facts setting field.
function themename_settings_field_facts() {
$options = themename_get_theme_options();
?>
<input type="text" name="themename_theme_options[facts]" id="facts" value="<?php echo esc_attr( $options['facts'] ); ?>" />
<br />
<span><?php printf( __( 'Default facts: %s', 'themename' ), '<span id="default-facts">' . themename_get_default_facts ( $options['color_scheme'] ) . '</span>' ); ?></span>
<?php
}
Sanitize and validate form input:
function themename_theme_options_validate( $input ) {
$output = $defaults = themename_get_default_theme_options();
// Color scheme must be in our array of color scheme options
if ( isset( $input['color_scheme'] ) && array_key_exists( $input['color_scheme'], themename_color_schemes() ) )
$output['color_scheme'] = $input['color_scheme'];
// Facts must be characters.
if ( isset( $input['facts'] ) )
$output['facts'] = '' . ( ltrim( $input['facts'], '' ) );
// Our defaults for the link color may have changed, based on the color scheme.
$output['link_color'] = $defaults['link_color'] = themename_get_default_link_color( $output['color_scheme'] );
// Link color must be 3 or 6 hexadecimal characters
if ( isset( $input['link_color'] ) && preg_match( '/^#?([a-f0-9]{3}){1,2}$/i', $input['link_color'] ) )
$output['link_color'] = '#' . strtolower( ltrim( $input['link_color'], '#' ) );
return apply_filters( 'themename_theme_options_validate', $output, $input, $defaults );
}
Implements theme options into Theme Customizer:
function themename_customize_register( $wp_customize ) {
$wp_customize->get_setting( 'blogname' )->transport = 'postMessage';
$wp_customize->get_setting( 'blogdescription' )->transport = 'postMessage';
$options = themename_get_theme_options();
$defaults = themename_get_default_theme_options();
$wp_customize->add_setting( 'themename_theme_options[facts]', array(
'default' => themename_get_default_facts( $options['color_scheme'] ),
'type' => 'option',
'sanitize_callback' => 'sanitize_text_field',
'capability' => 'edit_theme_options',
) );
}
add_action( 'customize_register', 'themename_customize_register' );
Thank you to anyone that can help :)
Thanks! I got it working :D

copy the code and create a new theme options file. Add the name and the variable_name in the options array in the file and you are good to go.
Don't forget to link this file in your functions.php
To link it just add the following code in your functions.php
require( dirname( __FILE__ ) . '/inc/your_file_name.php' );
