在woocommerce客户订单页面中执行PHP函数的按钮

我正在尝试制作一个按钮，它将在woocommerce的customers orders页面中执行我的FPDF脚本，以便客户可以根据按钮旁边的特定订单生成pdf

我已经添加了下面的my functions.php文件，为按钮创建了一个新列，并且添加了我希望按钮也执行的函数

我一直想知道如何在myaccount/orders.php文件中添加一个新按钮来执行该功能。在过去的两天里，我花了大部分时间试图找到一个解决方案——因此，任何帮助都将不胜感激

// END ENQUEUE PARENT ACTION

add_filter( 'woocommerce_account_orders_columns', 'add_custom_account_orders_column', 10, 1 );
function add_custom_account_orders_column( $columns ) {
$ordered_columns = array();

// Inserting a new column in a specific location
$ordered_columns['order-number'] = $columns['order-number'];
$ordered_columns['order-date'] = $columns['order-date'];
$ordered_columns['order-status'] = $columns['order-status'];
$ordered_columns['order-total'] = $columns['order-total'];
$ordered_columns['order-actions'] = $columns['order-actions'];
$ordered_columns['order-downloads'] =  __( 'Downloads', 'woocommerce' ); // <== New column

return $ordered_columns;
}

您可以使用按钮传递参数，然后在

init

hook上处理请求

    add_filter( 'woocommerce_account_orders_columns', 'add_custom_account_orders_column', 10, 1 );
    function add_custom_account_orders_column( $columns ) {
    $ordered_columns = array();

    // Inserting a new column in a specific location
    $ordered_columns['order-number'] = $columns['order-number'];
    $ordered_columns['order-date'] = $columns['order-date'];
    $ordered_columns['order-status'] = $columns['order-status'];
    $ordered_columns['order-total'] = $columns['order-total'];
    $ordered_columns['order-actions'] = $columns['order-actions'];
    $ordered_columns['order-downloads'] = __('Downloads', 'woocommerce'); // <== New column

    return $ordered_columns;
    }





function exFDPI () {
if(isset($_POST['order_id_for_pdf'])) {
require_once("/file/directory/FPDF.php");
//

return;
}
else {
return;
}     
}
add_action( 'init', 'exFDPI' );

首先，您缺少新专栏中的内容，下面是如何做到这一点：

步骤1：添加我们的专栏

add_filter('woocommerce_account_orders_columns', 'add_custom_account_orders_column', 10, 1);
function add_custom_account_orders_column($columns)
{
$ordered_columns = array();

// Inserting a new column in a specific location
$ordered_columns['order-number'] = $columns['order-number'];
$ordered_columns['order-date'] = $columns['order-date'];
$ordered_columns['order-status'] = $columns['order-status'];
$ordered_columns['order-total'] = $columns['order-total'];
$ordered_columns['order-actions'] = $columns['order-actions'];
$ordered_columns['order-downloads'] = __('Downloads', 'woocommerce'); // <== New column

return $ordered_columns;
}

//Insert the content into the new column 
function pdf_column_content($order)
{
    ?>



    <form action="<?php echo esc_url(admin_url('admin-post.php')); ?>" method="post">
    <?php wp_nonce_field('pdf_temp');?> //Security Check
        <input type="hidden" name="order_id" value="<?php echo $order->get_order_number() ?>">
        <input type="hidden" name="action" value="pdf_temp">
        <input type="submit" value="Submit">
    </form>


<?php 
}
add_action('woocommerce_my_account_my_orders_column_order-downloads', 'pdf_column_content');

//when the user click submit then we will call our template 
function exFDPI()
{

    $retrieved_nonce = $_REQUEST['_wpnonce']; 
    if (!wp_verify_nonce($retrieved_nonce, 'pdf_temp')) { //if passed the security check proceed 
        wp_die('Failed security check');
    } else {

        $order_id = $_POST['order_id'];
        echo $order_id;
        require_once "/file/directory/FPDF.php";
    }

}

add_action('admin_post_nopriv_pdf_temp', 'exFDPI');
add_action('admin_post_pdf_temp', 'exFDPI');

当然，完整的代码应该进入主题

functions.php

上面测试的代码

非常感谢您的回复！我试着把它放在functions.php中，它用Check更新的答案填充了一个表头。

//Insert the content into the new column 
function pdf_column_content($order)
{
    ?>



    <form action="<?php echo esc_url(admin_url('admin-post.php')); ?>" method="post">
    <?php wp_nonce_field('pdf_temp');?> //Security Check
        <input type="hidden" name="order_id" value="<?php echo $order->get_order_number() ?>">
        <input type="hidden" name="action" value="pdf_temp">
        <input type="submit" value="Submit">
    </form>


<?php 
}
add_action('woocommerce_my_account_my_orders_column_order-downloads', 'pdf_column_content');

//when the user click submit then we will call our template 
function exFDPI()
{

    $retrieved_nonce = $_REQUEST['_wpnonce']; 
    if (!wp_verify_nonce($retrieved_nonce, 'pdf_temp')) { //if passed the security check proceed 
        wp_die('Failed security check');
    } else {

        $order_id = $_POST['order_id'];
        echo $order_id;
        require_once "/file/directory/FPDF.php";
    }

}

add_action('admin_post_nopriv_pdf_temp', 'exFDPI');
add_action('admin_post_pdf_temp', 'exFDPI');
