User Meta stuff

Question

Ok I am trying to make a page the list user meta.

http://pastebin.com/rw1t7Mgp

The part I am stuck on is

$our_children = get_user_meta ($user_id,"our_children");

it is a meta field with an array in it.

a:1:{i:0;a:2:{s:4:"Name";s:6:"Elisha";s:3:"Age";s:2:"13";}}

How do I display the data in that array?

//foreach ( $our_children as $children ) { echo '<tr><td>'. $our_children-> Name .'</td><<td>'. $our_children-> Age .'</td></tr>'; //}

Doesn't seem to work?

Answer 1

You have a few PHP issues preventing output-

1. it appears your foreach is commented out with //.
2. you do foreach( $our_children as $children ), but then you use $our_children instead of $children inside the foreach.
3. $children->Age is for accessing an object's property, but what you have here is an array, so it should be $children['Age']

-

foreach ( $our_children as $children ) {
    echo '<tr><td>'. $children['Name'] .'</td><td>'. $children['Age'] .'</td></tr>';
}

WordPress stores arrays in the database as serialized data. Once you have retrieved it, you can use php's unserialize if you're sure of the format or WordPress's maybe_unserialize.

Note that in your example you're expecting an object, that won't always be the case, it depends on how the data was stored originally.
