Question

我今天刚刚完成了我的主题，并在主题设置页面中添加了css.php文件，我可以从面板中更改网站颜色。

标题中的

我添加了

<link rel='stylesheet' type='text/css' href="<?php bloginfo('template_directory'); ?>/css/style.php" />

但我想用if else

来使用它例如，

如果安装了主题并且主题设置中没有更改显示 <link rel='stylesheet' type='text/css' href="<?php bloginfo('template_directory'); ?>/css/style.css" /> css文件

但是当主题设置页面中的主题更改时，首先删除第一个css文件并显示

<link rel='stylesheet' type='text/css' href="<?php bloginfo('template_directory'); ?>/css/style.php" />

这可能吗？

Answer 1

您需要做的就是为主题设置保存操作添加一个标志。例如：

1：在你的插件或主题functions.php

中

add_action( 'optionsframework_after_validate', function(){ // this action is not real, you need to change it to your code
    update_option( 'theme-settings-changed', 'changed' );
});

2：在您的主题标题文件

中

$change_check = get_option( 'theme-settings-changed' );
if ( $change_check == 'changed' ) {
?>
    <link rel='stylesheet' type='text/css' href="<?php bloginfo('template_directory'); ?>/css/style.php" />
<?php
} else { 
?>
     <link rel='stylesheet' type='text/css' href="<?php bloginfo('template_directory'); ?>/css/style.css" />
<?php
}

此方法无法保证设置是否“实际”更改，因为它只是检查是否触发了保存按钮而不管设置更改。但是可以肯定的是，当用户更改值时会触发保存按钮。如果这还不够，你可以为此目的添加一个检查逻辑，虽然它会很乏味。
