每天更新一个插件的表单

Question

我需要在wordpress后端每天保存一次选项页(经典的"保存更改)。有什么办法吗?我拿了一个插件，我修改了它，从外部网站获得黄金价格。现在的问题是，我必须每天保存一次新的价格，我想安排"提交"。行动。

代码如下:

function woocommerce_gold_price_fields() {
$karats          = get_option( 'woocommerce_gold_price_options' );
$currency_pos    = get_option( 'woocommerce_currency_pos' );
$currency_symbol = get_woocommerce_currency_symbol();
?>
<table class="form-table widefat">
<thead>
<tr valign="top">
<th scope="col" style="padding-left: 1em;"><?php esc_html_e( 'Karats', 'woocommerce-gold-price' )?></th>
<th scope="col"><?php esc_html_e( 'Price', 'woocommerce-gold-price' ) ?></td>
<th scope="col"><?php esc_html_e( 'Weight Unit', 'woocommerce-gold-price' ) ?></td>
</tr>
</thead>


<?php 
$json = file_get_contents('https://data-asg.goldprice.org/dbXRates/EUR');
$decoded = json_decode($json);
$item = $decoded->items;
$date = $decoded->date;
$karats['24k'] = ($item[0]->xauPrice * 32.1507466);
//echo $karats['24k'];

$karats['22k'] = ($karats['24k'] * 0.9166);
$karats['20k'] = ($karats['24k'] * 0.833);
$karats['18k'] = ($karats['24k'] * 0.75);
$karats['14k'] = ($karats['24k'] * 0.583);/**/

您可以使用日程安排每天自动执行一次任务

// Schedule Cron Job Event
if ( ! wp_next_scheduled( 'register_price_gold_hook' ) ) {
wp_schedule_event( time(), 'twicedaily', 'register_price_gold_hook' );
}
add_action('register_price_gold_hook', 'register_price_gold');
function register_price_gold() {
// Update your Option Value with Gold Price
};
