Title: Retrieve values from an array Last modified: August 20, 2016 --- # Retrieve values from an array * Resolved [kevin heath](https://wordpress.org/support/users/ypraise/) * (@ypraise) * [13 years, 9 months ago](https://wordpress.org/support/topic/retrieve-values-from-an-array/) * Hi, * I’ve spent 2 days going crazy trying to retrieve a couple of vlaues from an array so I can display a google map. * I may end up re-wrting the way that users submit the form but if someone can offer a bit of advice first then it will be ideal. * The co-ordinates are sotred in an array called markers I know that the co-ordinates are being stored because when I run the following code; * ``` $custom_fields = get_post_custom_values('twitcher'); $my_custom_field = $custom_fields; foreach ( $my_custom_field as $key => $value ) echo "Retrieve co-ordinates - " . $key . " => " . $value . "
"; ``` * I get all the correct values printed out as such: * > Retrieve co-ordinates – 0 => a:9:{s:5:”title”;s:2:”zx”;s:4:”date”;s:10:”27/ > 08/2012″;s:4:”body”;s:3:”xxz”;s:7:”markers”;a:1:{i:0;a:2:{i:0;s:7:”51.6317″; > i:1;s:7:”-3.0378″;}}s:4:”zoom”;s:1:”7″;s:10:”image_file”;s:19:”twitcher_image_file”; > s:8:”category”;s:3:”268″;s:4:”name * What I need to do is pull out those marker co-ordinates so I can send them to the google api. * anyone help? * thanks Kevin Viewing 5 replies - 1 through 5 (of 5 total) * Moderator [keesiemeijer](https://wordpress.org/support/users/keesiemeijer/) * (@keesiemeijer) * [13 years, 9 months ago](https://wordpress.org/support/topic/retrieve-values-from-an-array/#post-3001112) * You are trying to get the “markers” value from a [serialized array](http://php.net/manual/en/function.serialize.php)( which is a string). * try it with this [untested]: * ``` foreach ( $my_custom_field as $key => $value ) { // WordPress function to unserialize (make it an array if it's a serialized array) $serialized = maybe_unserialize( $value ); if(is_array($serialized) && isset($serialized['markers'])) { // do stuff for your markers array echo '
';
             print_r($markers);
             echo '
'; } } ``` * [http://codex.wordpress.org/Function_Reference/maybe_unserialize](http://codex.wordpress.org/Function_Reference/maybe_unserialize) * Thread Starter [kevin heath](https://wordpress.org/support/users/ypraise/) * (@ypraise) * [13 years, 9 months ago](https://wordpress.org/support/topic/retrieve-values-from-an-array/#post-3001175) * Hi keesiemeijer thanks for the suggestion. It looks like another new wordpress function to learn about 😉 * It’s partially worked and did solve on of the problems I want to solve. * The problem is the the markers in an array within an array. Though with a bit of changes to your code I’ve been able to pull in the zoom level from the serialized data and pass it to the google api. * The code I used was * ``` $custom_fields = get_post_custom_values('twitcher'); $my_custom_field = $custom_fields; foreach ( $my_custom_field as $key =>$value){ $serialized = maybe_unserialize( $value ); if(is_array($serialized) && isset($serialized['zoom'])) { echo "Retrieve co-ordinates - " . $serialized['zoom'] . "
"; } } ``` * I was able to pass the zoom to the google maps api with: * ``` var myOptions = { zoom: , } ``` * I’m not quite sure how to pull out a serialized array within a serialized array. * thanks Kevin * Thread Starter [kevin heath](https://wordpress.org/support/users/ypraise/) * (@ypraise) * [13 years, 9 months ago](https://wordpress.org/support/topic/retrieve-values-from-an-array/#post-3001177) * Hi * I should just say that if I put in markers instead of zoom then I only get back the word ARRAY * Kevin * Thread Starter [kevin heath](https://wordpress.org/support/users/ypraise/) * (@ypraise) * [13 years, 9 months ago](https://wordpress.org/support/topic/retrieve-values-from-an-array/#post-3001179) * Hi * Thanks I’ve got it sorted on how to retrieve the values. Thanks keesiemeijer * ``` $custom_fields = get_post_custom_values('twitcher'); $my_custom_field = $custom_fields; foreach ( $my_custom_field as $key =>$value){ $serialized = maybe_unserialize( $value ); if(is_array($serialized) && isset($serialized['zoom'])) { echo "Retrieve zoom - " . $serialized['zoom'] .
