如何从 wordpress 的主题选项中获取输入文本？

Question

我刚刚在我的theme-options.php文件中设置了一个新的输入文本选项，类似于二十一主题代码。

以下是关于输入的部分我的 theme-options.php 代码，我正在寻找一种方法来获取用户输入到“事实”文本中的输入并将其显示在 index.php 页面上：

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' );

根据配色方案返回主题名称的默认事实：

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'];
}

呈现 Facts 设置字段。

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
}

清理和验证表单输入：

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 );
}

在主题定制器中实现主题选项：

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' );

感谢任何可以提供帮助的人 :) 谢谢！我得到了它的工作：D

复制代码并创建一个新的主题选项文件。在文件中的 options 数组中添加名称和 variable_name 即可。

不要忘记在你的functions.php中链接这个文件 要链接它，只需在您的 functions.php 中添加以下代码

require( dirname( __FILE__ ) . '/inc/your_file_name.php' );
