Hi,
\nI have a function in functions.php<\/p>\n

function updateHasReadFlag($user) {\n  \/\/ I added support for using this function either with user ID or user object\n  if ( $user && is_int( $user ) ) {\n    $user_id = $user;\n  } else if ( ! empty( $user->ID ) ) {\n    $user_id = $user->ID;\n  } else {\n    return;\n  }\n  return update_user_meta( $user_id, 'GDPR_TERMS_READ', true );\n}<\/code><\/pre>\n
Now I want to call this function on click of the Accept button from the GDPR pop up.<\/p>\n
<form method="post">\n            <?php if ($isshortcode == 1) : ?>\n            <input type="hidden" name="wptp_popup_id" value="<?php echo $termspageid; ?>" \/>\n            <?php endif; ?>\n\t\t\t<div class="tthebutton">\n\t\t\t\t<input class="termsagree" name="wptp_agree" type="submit" value="<?php echo $tagree; ?>" \/>\n\t\t\t    <input class="termsdecline" type="button" onclick="window.location.replace('<?php echo $termsRedirectUrl ?>')" value="<?php echo $tdisagree; ?>" \/>\n\t\t\t<\/div>\n\t\t<\/form><\/code><\/pre>\n
How can I do that?<\/p>\n","protected":false},"template":"","class_list":["post-11694787","topic","type-topic","status-publish","hentry"],"jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic\/11694787","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic"}],"about":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic\/11694787\/revisions"}],"wp:attachment":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/media?parent=11694787"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
