There are some values in Post Meta Data stored as a multi dimensional array. I want to update some of their data.
Here is the Post Meta value displayed using <?php the_meta(); ?>
voter: a:1:{s:5:"voter";a:5:
{s:7:"post_id";s:6:"219585";s:8:"voter_id";s:4:"1540";s:8:"voter_ip";s:13:"182.4
8.238.86";s:9:"author_id";s:4:"1540";s:4:"vote";s:1:"1";}},
a:1:{s:5:"voter";a:5:
{s:7:"post_id";s:6:"219585";s:8:"voter_id";s:3:"832";s:8:"voter_ip";s:13:"182.48
.238.86";s:9:"author_id";s:4:"1540";s:4:"vote";s:2:"-1";}},
a:1:{s:5:"voter";a:5:
{s:7:"post_id";s:6:"219585";s:8:"voter_id";s:2:"10";s:8:"voter_ip";s:13:"182.48.
238.86";s:9:"author_id";s:4:"1540";s:4:"vote";s:1:"1";}}
Now I want to update the vote
or voter_ip
where user_id
is 832 or 1540. I tried using update_post_meta()
but its updating everything.
So how to update the post meta of single value stored in multi dimension array?
Update:
array using the-meta()
