Tareq Hasan Hi. I have a field as POST TITLE. I'd like to save another hidden field with same data entered in POST TITLE field, without action by the user. When user is publish its post, simply reading POST TITLE value and save the same value with hidden meta key. Is this possible?

I saw this doc before, but I can’t use it.
You missed some information just like:
– In which files I need to put the code?

You can put this code in your themes functions.php.

First of all, thank you for support.

But, in this tutorial, you explain basic usage. How can I read value from another field of the same form?

Imagine that I put another field with date and I need to save another field with same entered date but with another format.
Could you extend the tutorial with some examples?

Here’s another example of reading a value from another field and updating another 🙂

As you are getting post id, you can get post title based on the post id and update to another meta_key.

Ok, it seems difficult but I’ll try today.

How can I do the same with a date field, changing date format in a second field?

The link above exactly gives an example how to do that!

The snippet you send me is about Woocommerce product, so code is displaying _price meta.

I can understand the example, but I need more information about how to retrieve another meta data, just like post title, and a lot of no-programmer user need this too…

I can’t find much information in tutorial.

function hereTheNameOfYourFunchtion( $post_id ) {
    $titleTheUserPutsIn = get_post_meta( $post_id, 'post_title', true );
    update_post_meta( $post_id, 'yourCustomField', $titleTheUserPutsIn );
add_action( 'wpuf_add_post_after_insert', 'hereTheNameOfYourFunchtion' );
add_action( 'wpuf_edit_post_after_update', 'hereTheNameOfYourFunchtion' );

I think this will work.

DenisCGN, I put your function but I get a blank key.
My custom field is created, but is blank.

I’m using the function with a hidden input field. Maybe this is the error?

I publish my code, because a lot of ways, but my custom field is saved blank:
function render_posttitle( $form_id, $post_id, $form_settings ) {
$value = get_post_meta( $post_id, ‘post_title’, true );
update_post_meta( $post_id, ‘meta_posttitle’, $value );
<div class="wpuf-fields">
<input type="hidden" name="my_posttitle" value="<?php echo esc_attr( $value ); ?>">
add_action( ‘hook_render_posttitle’, ‘render_posttitle’, 10, 3 );

/* Write meta key */
function get_posttitle( $post_id ) {
if ( isset( $_POST[‘my_posttitle’] ) ) {
update_post_meta( $post_id, ‘meta_posttitle’, $_POST[‘my_posttitle’] );

add_action( ‘wpuf_add_post_after_insert’, ‘get_posttitle’ );
add_action( ‘wpuf_edit_post_after_update’, ‘get_posttitle’ );

The code save always a blank key.

Sorry, here is the code:

Always a get a blank key.

Definitively it doesn’t work.
Sorry, I’m trying all possibile combinations, I get always a blank key.

The post title in WordPress is not a meta field. So you can’t get the post title via get_post_meta(), use get_post_field() for retrieving the post title.

Sorry, but I can’t make this code to work!
Why so difficult?

See latest version of my code here:

How is wrong?
