js不是wordpress通用，js仅用于7b2pro主题，因使用7b2js函数，其他主题可以更改Ajax，传输token。
提交页面HTML代码：
分类是自动获取网站的链接分类，可以改代码自定义设置。

}提交页面JS代码：
var xutianlinks = new Vue({

}
}).catch(err => {
Qmsg['info'](err.response.data.message, { html: true });
})
}
}
}
},
})后端处理PHP代码：
请将下方代码放入functions.php文件中
<?php
add_action('rest_api_init', function () {
register_rest_route('b2/v1', '/xutian_api_link/', array(
'methods' => 'POST',
'callback' => function ($request) {
$user_id = get_current_user_id();
$xutian_api_link = get_user_meta($user_id, 'xutian_api_link', true);
if (!$user_id) {
return new \WP_Error('b2_login', __('请先登录', 'b2'), array('status' => 403));
} else if ($xutian_api_link) {
return new \WP_Error('xutian_api_link', __('您已提交，请勿重复提交', 'b2'), array('status' => 403));
} else if ($request['link_name'] && $request['link_url'] && $request['link_category']) {
return api_link($request, $user_id);
} else {
return new \WP_Error('user_error', __('请输入必填项', 'b2'), array('status' => 403));
}
},
));
});
function api_link($request, $user_id)
{
$link_url = isset($request['link_url']) ? trim(sanitize_text_field(htmlspecialchars($request['link_url'], ENT_QUOTES))) : '';
$link_name = isset($request['link_name']) ? trim(sanitize_text_field(htmlspecialchars($request['link_name'], ENT_QUOTES))) : '';
$link_image = isset($request['link_image']) ? esc_url($request['link_image']) : '';
$link_category = isset($request['link_category']) ? trim(sanitize_text_field(htmlspecialchars($request['link_category'], ENT_QUOTES))) : '';
$link_description = isset($request['link_description']) ? trim(sanitize_text_field(htmlspecialchars($request['link_description'], ENT_QUOTES))) : '';
$link_notes = isset($request['link_notes']) ? trim(sanitize_text_field(htmlspecialchars($request['link_notes'], ENT_QUOTES))) : '';
if ($user_id and $link_name and $link_url and $link_category and $link_description = $link_name) {
$linkdata = array(
'link_name' => '【待审核】' . $link_name,
'link_url' => $link_url,
'link_image' => $link_image,
'link_category' => $link_category,
'link_notes' => $link_notes,
'link_description' => $link_description,
'link_target' => '_blank',
'link_visible' => 'N'
);
require_once(ABSPATH . 'wp-admin/includes/bookmark.php');
$xutian = wp_insert_link($linkdata);
update_user_meta($user_id, 'xutian_api_link', true);
if ($xutian) {
return array('status' => 200, 'msg' => '提交成功，待审核');
} else {
return new \WP_Error('user_error', __('提交失败，请联系管理员', 'b2'), array('status' => 403));
}
} else {
return new \WP_Error('user_error', __('提交失败，请完善资料', 'b2'), array('status' => 403));
}
}因防止恶意重复提交，代码中写入了
update_user_meta($user_id, ‘xutian_api_link’, true);，get_user_meta($user_id, ‘xutian_api_link’, true);判断，所以用户只能提交一次，删除这个代码就可以无限提交了，或自己改判断提交次数等。
