这应该放在页面上PHP脚本的顶部附近，以侦听提交的数据。
<?php
if (isset($_POST[\'user_adresse\'])) {
$userID = get_current_user_id();
$userADRESSE = $_POST[\'user_adresse\'];
update_user_meta($userID , \'user_adresse\' , $userADRESSE ); #\'user_adresse\' should be the name of the meta key
} ?>
表格应该是这样的
<?php $user_adresse = get_user_meta(get_current_user_id(), \'user_adresse\', true ); ?>
<form id="form_livraison" action="#formulaire" method=\'post\'>
<input type=\'text\' name=\'user_adresse\' value="<?php echo $user_adresse;?>" />
<input type=\'submit\' value=\'mettre à jour\' name=\'submit_form\' />
</form>
我还建议为任何前端用户交互在表单中添加nonce。
详细信息可以是found here 第节下Adding a nonce to a form
我没有测试过这段代码，所以请检查是否有拼写错误等！！
