[英]Set and use session data from a custom table redirecting to cart
我正在编写自定义 woocomerce 插件我有一个页面上的项目列表,当我在会话数组中按下它时,每个项目都有自己的添加按钮如下所示,单击添加按钮后,我不知道如何重定向到其他页面。 //项目列表页面:当有人点击添加按钮时,我想重定向到购物车页面。
<?php
function register_session(){
if(!session_id()) session_start();
}
add_action('init','register_session');
?>
<table border="1">
<tr>
<th>Item_ID</th>
<th>Item Description</th>
<th>Packing Size</th>
<th>Cart</th>
</tr>
<?php
$result1 = $wpdb->get_results ( "SELECT * FROM wp_orderlist where
category_id = $cat ");
foreach ( $result1 as $print1 ) {
echo '<tr>';
echo '<td>'. $print1->item_id.'</td>';
echo '<td>'. $print1->Item_Description.'</td>';
echo '<td>'. $print1->Packing.'</td>';
echo '<td> <form method="post"> <input type="submit" name="add"
href="$print1->item_id" value="ADD"></form> </td>';
echo '</tr>';
}
echo '</tr> ';
?>
</table>
</div>
<?php }
if (isset($_POST['add']))
{
$cart = array (
'oid' => $print1->item_id,
'des' => $print1->Item_Description,
'pack' => $print1->Packing
);
$_SESSION['cart'][] = $cart;
print_r($_SESSION['cart']);
}
?>
//I place this code on cart page to show data in array just for testing
//I am getting empty array.
<?php
$cart = ! empty( $_SESSION['cart'] ) ? $_SESSION['cart'] : false;
$_SESSION['cart'][] = $cart;
print_r($_SESSION['cart']);
exit;
?>
// I want automatic redirection to cart and want to show session
// data in one row table.
您的代码并不是真正可测试的,因为wp_orderlist
是一个自定义表并且$cat
未在您的代码中定义。 因此,我尝试使用模拟假数据,并在两个函数中设置了一些代码:
wp_orderlist
自定义表中获取必要的数据显示:您的页面代码将是:
<div> <?php // Missing opening div tag
?>
<table border="1">
<tr>
<th><?php _e("Item id","woocommerce"); ?></th>
<th><?php _e("Item Description","woocommerce"); ?></th>
<th><?php _e("Packing Size","woocommerce"); ?></th>
<th><?php _e("Action","woocommerce"); ?></th>
</tr>
<?php
foreach ( get_packing( $cat ) as $result ) : ?>
<tr>
<td><?php echo $result->item_id; ?></td>
<td><?php echo $result->Item_Description; ?></td>
<td><?php echo $result->Packing; ?></td>
<td> <a class="button alt" href="?cat=<?php echo $cat . '&packid=' . $result->item_id; ?>"><?php _e("Add","woocommerce"); ?></a></td>
</tr>
<?php endforeach; ?>
</table>
</div>
功能:(代码位于您的活动子主题(或活动主题)的 function.php 文件中:
// Utility function to get the data from "wp_orderlist" table
function get_packing( $cat, $id = '' ){
global $wpdb;
if( empty($id) ) {
// Get the results from the "category_id"
return $wpdb->get_results( "SELECT * FROM $wpdb->orderlist WHERE category_id = '$cat'");
} else {
// Get the row from the "category_id" and the "item_id"
return $wpdb->get_row( "SELECT * FROM $wpdb->orderlist WHERE category_id = '$cat' and item_id = '$id'");
}
}
// Set the chosen packing option data in session and redirect to cart page
add_action('template_redirect', 'grab_packing_option');
function grab_packing_option(){
if(session_id() == '' )
session_start();
if( isset( $_GET['cat'] ) && isset( $_GET['packid'] ) && ! isset($_SESSION['packing_option']) ){
$result = get_packing( $_GET['cat'], $_GET['packid'] );
// Set the chosen packing option data in session and redirect to cart page
if( $result->item_id == $_GET['packid'] && ! is_cart() ) {
$_SESSION['packing_option'] = $result; // Set data in session
wp_redirect( wc_get_cart_url() ); // Redirect to cart page
exit();
}
}
}
测试并使用一些模拟的假数据库表数据。
