如何從wordpress的主題選項獲取輸入文本？

Question

我只是在我的theme-options.php文件中設置了一個新的輸入文本選項，該文件類似於二十一個主題代碼。

以下是關於輸入的主題options.php代碼的一部分，我正在尋找一種方法來獲取用戶輸入到「事實」文本並在index.php頁面上顯示它的輸入：

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'); 

返回主題名稱默認事實的基礎上，配色方案：

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']; 
} 

呈現事實的設定欄。

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 
} 

消毒和驗證表單輸入：

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); 
} 

器具主題選項爲主題定製：

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'); 

謝謝你給任何人，可以幫助:) 謝謝！我得到它的工作：D

複製代碼並創建一個新的主題選項文件。在文件中的options數組中添加名稱和變量名稱，您很好。

不要忘了這個文件在你的functions.php 鏈接鏈接，它只是添加以下代碼到functions.php

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