Print Meta Data In Woocomerce Rest Api

Question

I am new to woocomerce Rest API. I am accessing all data from wordpress. Now i want to print the meta data. Api return me data in this json :-

[meta_data] => Array
                (
                    [0] => Array
                        (
                            [id] => 53380
                            [key] => slide_template
                            [value] => default
                        )

                    [1] => Array
                        (
                            [id] => 53381
                            [key] => payment_details
                            [value] => no data found
                        )

                    [2] => Array
                        (
                            [id] => 53382
                            [key] => wf_invoice_number
                            [value] => CNC04216
                        )
              )

After decoding of json i want to print this meta data. I am trying to print like this

<?php  echo $std[$k]['meta_data'][2]->wf_invoice_number; ?>

But may be its not a std Class object... How can i echo the meta data values.

I'm a little unclear what your problem is exactly - it seems that you have the values and the keys mixed up

The data from the question can be represented with this PHP snippet

$data=array(
    'meta_data'=>array(
        array('id'=>53380,'key'=>'slide_template','value'=>'default'),
        array('id'=>53381,'key'=>'payment_details','value'=>'no data found'),
        array('id'=>53382,'key'=>'wf_invoice_number','value'=>'CNC04216'),
    )
);

To show details from all parts yo can iterate through the top level array like this and access the items within using standard array notation.

foreach( $data['meta_data'] as $arr ){
    printf(
        '<pre>
            id: %s
            key: %s
            value: %s
        </pre>',
        $arr['id'],
        $arr['key'],
        $arr['value']
    );
}

This will output:

<pre>
    id: 53380
    key: slide_template
    value: default
</pre>
<pre>
    id: 53381
    key: payment_details
    value: no data found
</pre>
<pre>
    id: 53382
    key: wf_invoice_number
    value: CNC04216
</pre>

To access a specific record by index ( using the quoted index of 2 for instance )

#specific row
echo $data['meta_data'][2]['key']; // outputs: wf_invoice_number

To show the keys from a particular record, again at index 2:

#keys
printf('<pre>%s</pre>',print_r( array_keys( $data['meta_data'][2] ), true ) );

To show the corresponding values at the same index:

#values
printf('<pre>%s</pre>',print_r( array_values( $data['meta_data'][2] ), true ) );
