theme-options.php ファイルに新しい入力テキスト オプションを設定しました。これは、2011 のテーマ コードに似ています。
入力に関する私の theme-options.php コードの一部を次に示します。ユーザーが「事実」テキストに入力した入力を取得し、それを index.php ページに表示する方法を探しています。
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' );
配色に基づいて、テーマ名のデフォルトの事実を返します。
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'];
}
Facts 設定フィールドをレンダリングします。
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
}

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 );
}
テーマ オプションをテーマ カスタマイザーに実装します。
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' );
助けてくれる人に感謝します:)ありがとう!私はそれを働かせました:D
