我有一个主题，我放在一起，允许用户通过单击单选按钮来更改样式。我得到了没有验证回调的功能，但是因为在选项页面中添加了需要验证的文本字段。但现在风格变化的单选按钮不适用于验证（如果我不包含验证代码）。看起来像设置API需要验证一切。在搜索了两天的解决方案后，我找不到任何答案。我试图找出如何验证单选按钮代码或跳过单选按钮上的验证。下面是相关的代码：如何验证WordPress设置API中的单选按钮？
<?php
add_action('admin_init', 'mxs_admin_init');
add_action('admin_menu', 'mxs_admin_add_page');
function mxs_admin_add_page() {
add_theme_page(
'Mixin' Styles Theme Options',
'Mixin' Styles Theme Options',
'manage_options',
'mixinstyles',
'mxs_theme_options_page'
);
}
function mxs_admin_init() {
register_setting(
'mixinstyles_theme_options',
'mixinstyles_theme_options',
'mixinstyles_options_validate'
);
add_settings_section(// Styles section
'mixinstyles_main',
'Mixin' Styles Style Settings',
'mxs_theming_section_text',
'mixinstyles'
);
add_settings_field(
'custom_style_buttons',
'<strong>Color Schemes</strong>',
'mxs_custom_style_buttons',
'mixinstyles',
'mixinstyles_main'
);
...
function mxs_custom_style_buttons() {
$options = get_option('mixinstyles_theme_options');
//var_dump($options); //for debugging
echo "<div class='radiobutton-wrap'> \n";
echo "<div class='radiobutton-padding'> \n <input type='radio' id='default_style' value='default_style' name='mixinstyles_theme_options[custom_style_buttons]'" . checked($options['custom_style_buttons'], 1) .

function mxs_style_switcher() {
global $mixinstyles_theme_options;

switch ($options['custom_style_buttons']) { //opens switch statement

function mixinstyles_options_validate($input) { //opens mixinstyles_options_validate function
$options = get_option('mixinstyles_theme_options');
//for each radio button
//default
$options['default_style'] = $input['default_style'];
if (!isset($input['default_style'])) {
}
//blue orange
$options['blue_orange'] = $input['blue_orange'];
if (!isset($input['blue_orange'])) {
}
//violet yellow
$options['violet_yellow'] = $input['violet_yellow'];
if (!isset($input['violet_yellow'])) {
}
//magenta green
$options['magenta_green'] = $input['magenta_green'];
if (!isset($input['magenta_green'])) {
}
//orange blue
$options['orange_blue'] = $input['orange_blue'];
if (!isset($input['orange_blue'])) {
}
//yellow violet
$options['yellow_violet'] = $input['yellow_violet'];
if (!isset($input['yellow_violet'])) {
}
return $options;
}
?>
我有功能类似的验证了这样写的一个复选框：
//check if checkbox has been checked
$options['remove_blogtitle'] = $input['remove_blogtitle'];
if (!isset($input['remove_blogtitle'])) {
$input['remove_blogtitle'] = null;
}
我和单选按钮尝试这样做，但它不工作。
