保存/重置主题选项页面时，如何获取备用样式表加载到wp_head中（） _WordPress开发

我希望我可以在如何将两个不同的嵌入式样式表加载到head标签(wp_head操作钩)中获得帮助, 这取决于用户是否在主题选项页面中单击保存或重置。
现在的设置方式, 仅保存在数组开头指定的选项(用户键入的选项), 而不保存其他样式表。现在, 我有一个名为test1()和test2()的占位符函数代替了将要加载到wp_head中的实际样式表。下面是我的代码。测试功能下方注释掉的部分是我试图使此功能正常工作的部分。

< ?php // add the admin options page $themename = "Cool Orange"; $shortname = "co"; $options = array ( array ( "name" => "Main Settings", "type" => "title" ), array ( "type" => "open" ), array ( "name" => "Upload logo to the Media Library:", "id" => $shortname."_logo_label", "std" => "", "type" => "label" ), array ( "name" => "Logo location:", "desc" => "In this section, you can replace the standard blog title heading with a custom logo. The logo cannot be wider than 960 pixels.", "id" => $shortname."_logo_url", "std" => "", "type" => "text" ), array ( "name" => "Logo width:", "desc" => "Enter logo width in pixels, for example < strong> 800px< /strong> ", "id" => $shortname."_logo_width", "std" => "", "type" => "text" ), array ( "name" => "Logo height:", "desc" => "Enter logo height in pixels, for example < strong> 90px< /strong> ", "id" => $shortname."_logo_height", "std" => "", "type" => "text" ), array( "type" => "close" )); function mytheme_add_admin() { global $themename, $shortname, $options; if ( $_GET['page'] == basename(__FILE__) ) { if ( 'save' == $_REQUEST['action'] ) { foreach($options as $value) { update_option( $value['id'], $_REQUEST[ $value['id'] ] ); } foreach ($options as $value) { if( isset( $_REQUEST[ $value['id'] ] ) ) { update_option( $value['id'], $_REQUEST[ $value['id'] ]); } else { delete_option( $value['id'] ); } } header("Location: themes.php?page=functions.php& saved=true"); die; } else if( 'reset' == $_REQUEST['action'] ) { foreach ($options as $value) { delete_option( $value['id'] ); } header("Location: themes.php?page=functions.php& reset=true"); die; } } add_theme_page($themename." Options", "".$themename." Options", 'edit_themes', basename(__FILE__), 'mytheme_admin'); }function mytheme_admin() { global $themename, $shortname, $options; if ( $_REQUEST['saved'] ) echo '< div id="message" class="updated fade"> < p> < strong> '.$themename.' settings saved.< /strong> < /p> < /div> '; if ( $_REQUEST['reset'] ) echo '< div id="message" class="updated fade"> < p> < strong> '.$themename.' settings reset.< /strong> < /p> < /div> '; ?> < div class="wrap"> < h2> < ?php echo $themename; ?> Theme Options< /h2> < form method="post"> < h3> How to upload a logo to replace the heading< /h3> < div style="background-color: #FFFFFF; border: 1px solid #BBBBBB; padding: 30px; "> < ul style="list-style: disc; "> < li> Upload the image from your computer to the Media Library using the < strong> Upload image< /strong> button below< /li> < li> Go to the < strong> Media< /strong> button at the left to acces the Media Library.

我也乐于接受其他替代方法。
#1经过仅两天的反复试验, 看来我找到了解决方案, 或更确切地说, 是解决此问题的方法。我遵循了有关如何从主题选项页面内切换样式表的教程。该教程称为” 将样式切换器添加到WordPress主题” 。在本教程中, 作者从选择下拉菜单切换外部样式表。在我的代码中, 我将外部样式表换成了嵌入式样式表。就我上面的问题而言, 这将是test1和test2函数。
代码示例为：
【保存/重置主题选项页面时，如何获取备用样式表加载到wp_head中（）】在顶部添加一个新数组

array ( "name" => "Restore CSS", "desc" => "Restore the original heading text", "id" => $shortname."_restore_css", "type" => "select", "options" => array ("select an option", "test2"), "std" => "Logo CSS" ),

然后添加一个新功能, 在本例中为css_switcher

function css_switcher() { //opens css_switcher functionglobal $options; foreach ($options as $value) { if (get_settings( $value['id'] ) === FALSE) { $$value['id'] = $value['std']; } else { $$value['id'] = get_settings( $value['id'] ); } }?> < !-- logo stylesheet goes outside of switch statement --> < ?php switch ($co_restore_css) {//opens switch statement case "select an option": //nothing goes between this closing php tag and // next opening php tag, to make select an option do nothing ?> < ?php break; case "Restore CSS": ?> < !-- restore stylesheet goes inside of switch statement --> < ?php break; }//closes switch statement}//closes css_switcher_functionadd_action('wp_head', 'css_switcher'); ?>

这对我有用。
