Hi, I'm trying to add another Checkbox, that calls the php func mark_as_unread. But can't get it work properly.
(function ($) {
$(function () {
// If the "I've Read This Container" is on this page, let's setup the event handler
if(1 === $('#ive-read-this-container').length) {
// We use the change attribute so that the event handler fires
// whenever the checkbox or its associated label is clicked.
$('input[name="ive-read-this"]').change(function (evt) {
alert("markiere als gelesen.");
// We can retrieve the ID of this post from the <article>'s ID. This will be required
// so that we can mark that the user has read this particular post and we can hide it.
var sArticleId, iPostId;
// Get the article ID and split it - the second index is always the post ID in twentyeleven
sArticleId = $("article").attr('id');
iPostId = parseInt(sArticleId.split('-')[1]);
// Initial the request to mark this this particular post as read
$.post(ajaxurl, {
action: 'mark_as_read',
post_id: iPostId
}, function (response) {
console.log(response);
// If the server returns '1', then we can mark this post as read, so we'll hide the checkbox
// container. Next time the user browses the index, this post won't appear
if (1 === parseInt(response)) {
$('#ive-read-this-container').slideUp('fast');
// Otherwise, let's alert the user that there was a problem. In a larger environment, we'd
// want to handle this more gracefully.
} else {
alert("There was an error marking this post as read. Please try again.");
} // end if/else
});
});
// We use the change attribute so that the event handler fires
// whenever the checkbox or its associated label is clicked.
$('input[name="unread"]').change(function (evt) {
alert("markiere als ungelesen.");
// We can retrieve the ID of this post from the <article>'s ID. This will be required
// so that we can mark that the user has read this particular post and we can hide it.
var sArticleId, iPostId;
// Get the article ID and split it - the second index is always the post ID in twentyeleven
sArticleId = $("article").attr('id');
iPostId = parseInt(sArticleId.split('-')[1]);
// Initial the request to mark this this particular post as unread
$.post(ajaxurl, {
action: 'mark_as_unread',
post_id: iPostId
}, function (response) {
console.log(response);

// container. Next time the user browses the index, this post won't appear

} else {
alert("There was an error marking this post as unread. Please try again.");
} // end if/else
});
});
} // end if
});
}(jQuery));
public function mark_as_unread() {
// First, we need to make sure the post ID parameter has been set and that's it's a numeric value
if( isset( $_POST['post_id'] ) && is_numeric( $_POST['post_id'] ) ) {
// If we fail to update the user meta, respond with -1; otherwise, respond with 1.
echo false == update_user_meta( wp_get_current_user()->ID, $_POST['post_id'], 'ive_unread_this' ) ? "-1" : "1";
} // end if
die();
} // end mark_as_unread
