我想在我的 wordpress 主题选项中设置一些默认值,以便在激活主题时,我可以获得字段的默认值。以下是我的代码,它在主题选项页面中显示默认值,但在保存选项之前我无法获取变量中的默认值。无论如何在保存之前从主题选项中获取默认值?谢谢。
//set default options
$sa_options = array(
'footer_copyright' => '© ' . date('Y') . ' ' . get_bloginfo('name'),
'intro_text' => 'some text',
'featured_cat' => ''
);
//register settings
function sa_register_settings() {
register_setting( 'sa_theme_options', 'sa_options', 'sa_validate_options' );
}
add_action( 'admin_init', 'sa_register_settings' );
//add theme options page
function sa_theme_options() {
add_theme_page( 'Theme Options', 'Theme Options', 'edit_theme_options', 'theme_options', 'sa_theme_options_page' );
}
add_action( 'admin_menu', 'sa_theme_options' );
// Function to generate options page
function sa_theme_options_page() {
global $sa_options;
<?php if ( false !== $_REQUEST['updated'] ) : ?>
<div class="updated fade"><p><?php _e( 'Options saved' ); ?></p></div>
<?php endif; ?>
<form method="post" action="options.php">
<?php $settings = get_option( 'sa_options', $sa_options ); ?>
<?php settings_fields( 'sa_theme_options' ); ?>
<input id="footer_copyright" name="sa_options[footer_copyright]" type="text" value="<?php esc_attr_e($settings['footer_copyright']); ?>" />
