Accessing Post and Pages Custom Fields

Posted on by sanraul

If you know the ID of post or page you can access the custom fields by using the {meta...} tag:

1
2
3

{meta post_id="23" assign_to="custom_fields"}
 
{dump var="custom_fields"}
{meta post_id="23" assign_to="custom_fields"}

{dump var="custom_fields"}

This should output an array similar to the one below:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
22
23
24
25

array(6) {
  ["success"]=>
  bool(true)
  ["message"]=>
  string(7) "success"
  ["action"]=>
  string(14) "appc_post_meta"
  ["route"]=>
  string(14) "appc.post.meta"
  ["post_id"]=>
  string(3) "513"
  ["data"]=>
  array(5) {
    ["_edit_lock"]=>
    string(13) "1431444730:11"
    ["_edit_last"]=>
    string(2) "11"
    ["_thumbnail_id"]=>
    string(3) "509"
    ["_wp_page_template"]=>
    string(7) "default"
    ["icon"]=>
    string(32) "/resources/img/features-ico2.png"
  }
}
array(6) {
  ["success"]=>
  bool(true)
  ["message"]=>
  string(7) "success"
  ["action"]=>
  string(14) "appc_post_meta"
  ["route"]=>
  string(14) "appc.post.meta"
  ["post_id"]=>
  string(3) "513"
  ["data"]=>
  array(5) {
    ["_edit_lock"]=>
    string(13) "1431444730:11"
    ["_edit_last"]=>
    string(2) "11"
    ["_thumbnail_id"]=>
    string(3) "509"
    ["_wp_page_template"]=>
    string(7) "default"
    ["icon"]=>
    string(32) "/resources/img/features-ico2.png"
  }
}

Here is a complete example that show how to request children pages and their custom fields meta data:

<div id="features">

        <div class="section_header">
            <h3>Features</h3>
        </div> 
        
        {foreach $features_pages.data as $feature}
        {meta post_id="{$feature.ID}" assign_to="meta"}
        {dump var="meta"}
        <div class="row feature">
            <div class="col-sm-6 {if $feature@index%2 == 1}pic-right{/if}">

                <h3>
                    <img src="{$meta.data.icon}" />
                    {$feature.post_title}
                </h3>
                {$feature.post_content_filtered}
            </div>
        </div>
        {/foreach}
    </div>

        {foreach $features_pages.data as $feature}
        {meta post_id="{$feature.ID}" assign_to="meta"}
        {dump var="meta"}
        <div class="row feature">

            </div>
            <div class="col-sm-6 info{if $feature@index%2 == 1}-left{/if}">
                <h3>
                    <img src="{$meta.data.icon}" />
                    {$feature.post_title}
                </h3>
                {$feature.post_content_filtered}
            </div>
        </div>
        {/foreach}
    </div>
</div>
