I am trying to get an associative aray from a form input, which works ok. But i dont want the new value to duplicate if the key already exist in the array. Here is how my $_POST function looks:
<?php // top of page
if ( isset( $_POST['drw_inventory'] ) && wp_verify_nonce($_POST['drw_inventory'],'update_drw_postmeta') )
{
//if nonce check succeeds.
global $post;
$postid = $post->ID;
$data = $_POST['wpd_function_rating'];
$currentusr = wp_get_current_user();
//Get the Existing user ratings of this post
$ls_up_votes = (get_post_meta($postid, 'wpd_rating', TRUE ));
//if the current user already rated, unset the rating
foreach($ls_up_votes as $arr) {
foreach($arr as $key => $value) {
if (array_key_exists($currentusr->user_login, $arr)) {
unset($arr[$key]);
}
}
}
//Add post meta 'wpd_rating' with this structure:
$ls_up_votes[] = array($currentusr->user_login => $data);
update_post_meta($postid,'wpd_rating',$ls_up_votes);
}
?>
The Form
<form method="post" action="">
<?php wp_nonce_field('update_drw_postmeta','drw_inventory'); ?>
<label>This is label</label>
<input type='text' name='wpd_function_rating' value='' />
<input type='submit' value='save' />
</form>
This is how my array looks(you can see the duplicate user inputs, I want the array value to be updated on the existing username key):
Array (
[0] => Array ( [user1] => 33 )
[1] => Array ( [user1] => 44 )
[2] => Array ( [user2] => 34 )
[2] => Array ( [user2] => 31 )
)
Any help would be appreciated.
foreach ( $ls_up_votes as $k => $v ) {
foreach ( $v as $k2 => $v2 ) {
if ( array_key_exists($currentusr->user_login, $v) ) {
unset($ls_up_votes[$k][$k2]);
}
}
}
