我想在“主题选项”上创建自定义表单
基本上，我已经构建了：
/* == THEME OPTIONS == */
// This tells WordPress to call the function named "setup_theme_admin_menus"
// when it\'s time to create the menu pages.
add_action("admin_menu", "setup_theme_admin_menus");
function setup_theme_admin_menus() {
add_submenu_page(\'themes.php\',
\'Generate Coupons\', \'Generate Coupons\', \'manage_options\',
\'generate-coupons-elements\', \'theme_generate_coupons_settings\');
}
function theme_generate_coupons_settings() {
?>
<div class="wrap">
<?php screen_icon(\'themes\'); ?> <h2>Generate Coupons</h2>
<form method="POST" action="">
<table class="form-table">
<tr valign="top">
<th scope="row">
<label for="coupon">
Number of coupons:
</label>
</th>
<td>
<input type="text" name="coupon" size="25" />
</td>
</tr>
<tr valign="top">
<th scope="row">
<label for="discount">
Amount of discount:
</label>
</th>
<td>
<input type="text" name="discount" size="25" />
</td>
</tr>
</table>
<p>
<input type="submit" value="Generate" class="button-primary"/>
</p>
</form>
</div>
<?php
}
/* == END OF THEME OPTIONS == */
在我的仪表板上显示字段表单的代码。
我在WooCommerce文档中看到：
$coupon_code = \'UNIQUECODE\'; // Code
$amount = \'10\'; // Amount
$discount_type = \'fixed_cart\'; // Type: fixed_cart, percent, fixed_product, percent_product
$coupon = array(
\'post_title\' => $coupon_code,
\'post_content\' => \'\',
\'post_status\' => \'publish\',
\'post_author\' => 1,
\'post_type\' => \'shop_coupon\'
);
$new_coupon_id = wp_insert_post( $coupon );
// Add meta
update_post_meta( $new_coupon_id, \'discount_type\', $discount_type );
update_post_meta( $new_coupon_id, \'coupon_amount\', $amount );
update_post_meta( $new_coupon_id, \'individual_use\', \'no\' );
update_post_meta( $new_coupon_id, \'product_ids\', \'\' );
update_post_meta( $new_coupon_id, \'exclude_product_ids\', \'\' );
update_post_meta( $new_coupon_id, \'usage_limit\', \'\' );
update_post_meta( $new_coupon_id, \'expiry_date\', \'\' );
update_post_meta( $new_coupon_id, \'apply_before_tax\', \'yes\' );
update_post_meta( $new_coupon_id, \'free_shipping\', \'no\' );
我的问题是，如何让我的第一个代码运行第二个代码并捕获从该代码发送的变量？我知道第二个代码只生成1张优惠券，但稍后我可以根据表单发送的“优惠券”编号循环它。
我希望你能在这件事上帮助我。
非常感谢。

经过多次尝试和错误，我终于找到了答案。
如果有人想知道这是如何工作的，我将完整的代码放在这里：
/* == THEME OPTIONS == */
add_action("admin_menu", "setup_theme_admin_menus");
function setup_theme_admin_menus() {
add_submenu_page(\'themes.php\',
\'Generate Coupons\', \'Generate Coupons\', \'manage_options\',
\'generate-coupons-elements\', \'theme_generate_coupons_settings\');
}
function theme_generate_coupons_settings() {
?>
<div class="wrap">
<?php screen_icon(\'themes\'); ?> <h2>Generate Coupons</h2>
<form method="POST" action="">
<table class="form-table">
<tr valign="top">
<th scope="row">
<label for="coupon">
Number of coupons:
</label>
</th>
<td>
<input type="text" name="coupon" size="25" />
</td>
</tr>
<tr valign="top">
<th scope="row">
<label for="discount">
Amount of discount:
</label>
</th>
<td>
<input type="text" name="discount" size="25" />
</td>
</tr>
</table>
<p>
<input type="hidden" name="update_settings" value="Y" />
<input type="submit" value="Generate" class="button-primary"/>
</p>
</form>
</div>
<?php
if (isset($_POST["update_settings"])) {
$coupon = esc_attr($_POST["coupon"]);
$discount = esc_attr($_POST["discount"]);
$coupon_code = \'UNIQUECODES\'; // Code
$amount = $discount; // Amount
$discount_type = \'fixed_cart\'; // Type: fixed_cart, percent, fixed_product, percent_product
$coupon = array(
\'post_title\' => $coupon_code,
\'post_content\' => \'\',
\'post_status\' => \'publish\',
\'post_author\' => 1,
\'post_type\' => \'shop_coupon\'
);
$new_coupon_id = wp_insert_post( $coupon );
// Add meta
update_post_meta( $new_coupon_id, \'discount_type\', $discount_type );
update_post_meta( $new_coupon_id, \'coupon_amount\', $amount );
update_post_meta( $new_coupon_id, \'individual_use\', \'no\' );
update_post_meta( $new_coupon_id, \'product_ids\', \'\' );
update_post_meta( $new_coupon_id, \'exclude_product_ids\', \'\' );
update_post_meta( $new_coupon_id, \'usage_limit\', \'1\' );
update_post_meta( $new_coupon_id, \'usage_limit_per_user\', \'1\' );
update_post_meta( $new_coupon_id, \'expiry_date\', \'\' );
update_post_meta( $new_coupon_id, \'apply_before_tax\', \'yes\' );
update_post_meta( $new_coupon_id, \'free_shipping\', \'no\' );
?>
<div id="message" class="updated">Coupon generated!</div>
<?php
}
}
/* == END OF THEME OPTIONS == */
