As the question states, how do I copy an ACF field from one post to another? This is what I have so far. Any help would be appreciated.
add_action('save_post', 'dupe-expiration-date');
function dupe-expiration-date()
{
// Gets expiration date from 'Homepage' page
$date_field_data = get_field('sale_expiration_date', 2361);
// Sets expration date on 'Deals' page
update_field('sale_expiration_date', $date_field_data, 34412);
}
Essentially, my code works. I don't know PHP so when I created the function dupe-expiration-date, I didn't know I couldn't use the character '-' to name the function.
Once I corrected that issue, the code worked as intended.

etc every time n value change.
and also i want get n value in page-download.php
please tell me how to do it . i know how to work in php simple but in wordpress its not work
Why just not use, echo $_GET['n'] ?
When you hit this page directly from the URL like below, please change your parameter, because of that I have tried same method few days ago and I can't get the parameter value.
http://example.com/download?from_browser=skype
http://example.com/download?from_browser=firefox
You can get the value like below or as per the reference :
$blah = get_query_var( 'from_browser');
if(isset($blah)) // Your code will be here
Hope this help!!!
So I have a post meta field that has two values, true or false. It is defaulted at false, and it'll automatically change to true when an event occurs.
Anyway, is it possible to create another meta field that records the exact time that this change occurs? If so, how would I go about doing this?
Well without modifying wordpress core or overriding the update_field() function in your theme functions.php you cant get in a smooth way the time when a record has been added to the database.
But what can i advice to you:
1) If your application highly depends on seconds:milliseconds when post_meta has been modified, you should use advanced technique: database transactions.
2) If your application are fine with a small delay between writing up 1st meta and the second just add it with add_post_meta() right below the update_field() performed
p.s If you think that overriding the function with functions.php is the way you prefer just ping me a comment, i'll try to help you with by editing the post.
Cheers!
EDIT
Right after your manipulation with allready_aired field performed
$alreadyAired = get_field('already_aired', $episodeID);
if (get_field('already_aired', $episodeID) == "no") {
update_field('field_28', "yes", $episodeID);
}
you can use add_post_meta($post_id, $meta_key, $meta_value, $unique) function in a way like this:
$alreadyAired = get_field('already_aired', $episodeID);
if (get_field('already_aired', $episodeID) == "no") {
update_field('field_28', "yes", $episodeID);
}
add_post_meta($episodeID, 'NEW_TIMESTAMP_FIELD', time(), true);
Then, you can call this NEW_TIMESTAMP_FIELD and use in a way you like (echo formatted date-string, compare 2 dates, etc.
Please note the 4th parameter of add_post_meta function. This one tell you that this field is unique and considering that app_post_meta does not affect "Update" actions, this bundle wont let this field get modified in the second time.
I am trying to set a custom cookie when a visitor submits a comment, but I can not seem to get this working. Here's what I have in functions.php:
add_action('comment_post', 'ipro_set_comment_cookie');
function ipro_set_comment_cookie($comment) {
setcookie("visitor_name", $comment->comment_author, time()+86400);
setcookie("visitor_email", $comment->comment_author_email, time()+86400);
}
I've also tried changing comment_post to wp_insert_comment- neither have seemed to work. I am working off of WP's action references:
http://codex.wordpress.org/Plugin_API/Action_Reference#Comment.2C_Ping.2C_and_Trackback_Actions
...any ideas?
Check out the Database writes in the Filter Reference
Try something like comment_save_pre
applied to the comment data just prior to updating/editing comment data. Function arguments: comment data array, with indices "comment_post_ID", "comment_author", "comment_author_email", "comment_author_url", "comment_content", "comment_type", and "user_ID".
That way it sets on submit (so it calls after your error handling kicks in)
If I understand your question correctly, this should work:
add_action('comment_save_pre', 'ipro_set_comment_cookie');
function ipro_set_comment_cookie($comment) {
setcookie("visitor_name", $comment->comment_author, time()+86400);
setcookie("visitor_email", $comment->comment_author_email, time()+86400);
}
I have a question about the optional_param function in a form in PHP (version 5.3.14)
After looking over why certain fields were not being saved in a form I have, I realised that this data...
$checkdata = optional_param('items', array(), PARAM_INT)
Only saves up to 996 places (items) from the form (they are select items and there are many)....
Is this a setting or a something I can change? or alternatively something wrong from my end?
Thanks in advance
Solution : A moodle function (platform i am working with)
Thanks Pekka
this function is a moodle function. It gets a parameter from the current page URL.
For an example url:
http://moodle.dev/course/view.php?id=2&items=4
(this is chosen totally arbitrary)
Using this code:
$checkdata = optional_param('items', array(), PARAM_INT)
Will save the "items" value (here it's 4) in $checkdata. If items does not exist in the url it will do $checkdata = array()
I'd like to use a custom post type archive as a site's front page, so that
http://the_site.com/
is a custom post type archive displayed according to my archive-{post-type}.php file.
Ideally I would like to alter the query using is_front_page() in my functions.php file. I tried the following, with a page called "Home" as my front page:
add_filter('pre_get_posts', 'my_get_posts');
function my_get_posts($query){
global $wp_the_query;
if(is_front_page()&&$wp_the_query===$query){
$query->set('post_type','album');
$query->set('posts_per_page',-1);
}
return $query;
}
but the front page is returning the content of "Home" and seems to be ignoring the custom query.
What am I doing wrong? Is there a better way, in general, of going about this?
Note: I did post this in WordPress Answers but that community is comparatively tiny.
Posting the final solution as an answer (Isaac placed it as a comment) just for anyone still looking.
Isaac was on the right track with adding a filter via functions.php. What he did wrong was call is_front_page(), which doesn't work yet because we're in pre_get_posts and the query hasn't been executed yet.
We do have the current page ID however. So we can still solve this, by looking into the WordPress option register for an option called page_on_front, which returns the ID of the page the user set as frontpage.
(For an overview of all WordPress options, just visit <yourwordpressinstallation>/wp-admin/options.php in your browser.)
Which makes for the following solution as suggested by Ijaas:
add_action("pre_get_posts", "custom_front_page");
function custom_front_page($wp_query) {
// Compare queried page ID to front page ID.
if(!is_admin() && $wp_query->get("page_id") == get_option("page_on_front")) {
// Set custom parameters (values based on Isaacs question).
$wp_query->set("post_type", "album");
$wp_query->set("posts_per_page", -1);
// WP_Query shouldn't actually fetch the page in our case.
$wp_query->set("page_id", "");
}
}
You might have to alter a few conditional tags to make sure all plugins still work, depending on how heavily the query gets altered.
Hope this helps someone.
Update: as noted below, add !is_admin() to the if-statement to make sure the function only runs on the frontend. If you only want this action to run for the initial query, you could also add the main query check $wp_query->is_main_query().
In response to Robberts solution:
answered May 6 '13 at 12:04
adding && !isAdmin() to the if function other wise it replaces the post type query for all admin pages as well.
Just in case anyone has issues with this.
edit:
also adding && $wp_query->is_main_query() to the if statement stops it affecting widgets and the menu
so total code I have
if($wp_query->get("page_id") == get_option("page_on_front") && !isAdmin() && $wp_query->is_main_query()) {}
In order to get that query to work, you're going to have to add that code to a page template, create a page, set your template as the template for the page you just created, and then set that page as the home page in Settings => Reading in the admin area.
By the way, the is_front_page() function only returns true if you're on a page that's been set as the home page from the admin menu.
The other option would be to modify index.php, but if you did that, is_front_page() would always return false. In that case, you'd want to use is_home() instead.
I hope that helps.
Isaac, you are correct, I didn't thoroughly read your question and I made the assumption that you were looking to do this the "easy" way.
Anyway, I put your code on my test site and, indeed, it didn't work. I looked at my SQL log and it turns out that your code produces this in the query wp_posts.post_status = 'private'.
So, I tried adding the line $query->set('post_status', 'public'); to your function, and it worked just fine.
In summary, try this:
add_filter('pre_get_posts', 'my_get_posts');
function my_get_posts($query){
global $wp_the_query;
if(is_front_page()&&$wp_the_query===$query){
$query->set('post_type','album');
$query->set('posts_per_page',-1);
$query->set('post_status', 'public');
}
return $query;
}
