增加值而不是使用WordPress更新user

增加值而不是使用WordPress更新user_meta(Increase value instead of updating user_meta with WordPress)

所以，我使用以下代码来允许人们将步兵或车辆添加到他们的个人资料中

function after_submission($form) { $user = wp_get_current_user(); $user_id = $user->ID; $infantry = $form[1]; $vehicle = $form[2]; update_user_meta( $user_id, 'infantry', $infantry); update_user_meta( $user_id, 'vehicle', $vehicle);

我的问题是步兵和车辆正在更新，而不是增加。

有什么建议么？

So, I'm using the following code to allow people to add infantry or vehicle to their profile

function after_submission($form) { $user = wp_get_current_user(); $user_id = $user->ID; $infantry = $form[1]; $vehicle = $form[2]; update_user_meta( $user_id, 'infantry', $infantry); update_user_meta( $user_id, 'vehicle', $vehicle);

My problem is that infantry & vehicle is getting updated, rather than increased.

Any suggestions?

试试这样：

$user = wp_get_current_user(); $user_id = $user->ID; $infantry = $form[1]; $vehicle = $form[2]; $oldInfantry = get_user_meta( $user_id, 'infantry', true); $oldVehicle = get_user_meta( $user_id, 'vehicle', true); update_user_meta( $user_id, 'infantry', $infantry+$oldInfantry); update_user_meta( $user_id, 'vehicle', $vehicle+$oldVehicle);

try like this:

$user = wp_get_current_user(); $user_id = $user->ID; $infantry = $form[1]; $vehicle = $form[2]; $oldInfantry = get_user_meta( $user_id, 'infantry', true); $oldVehicle = get_user_meta( $user_id, 'vehicle', true); update_user_meta( $user_id, 'infantry', $infantry+$oldInfantry); update_user_meta( $user_id, 'vehicle', $vehicle+$oldVehicle);
