Ok I am trying to make a page the list user meta.
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?
You have a few PHP issues preventing output-
//.foreach( $our_children as $children ), but then you use $our_children instead of $children inside the foreach.$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>';
}
$children was an object, the space in $children-> Age and $children-> Name would cause issues.
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.
get_user_meta itself uses maybe_unserialize, if you're getting serialized data back from that function there's something wrong.
