Get array value

Question

I want to get a custom post value from post ID

PHP code :

$custom_field = get_post_meta(2055, the_field('titdesc'));
var_dump($custom_field);`

Output :

array(6) {
  ["_edit_last"]=>
  array(1) {
    [0]=>
    string(1) "1"
  }
  ["_edit_lock"]=>
  array(1) {
    [0]=>
    string(12) "1373450528:1"
  }
  ["_wp_page_template"]=>
  array(1) {
    [0]=>
    string(8) "work.php"
  }
  ["titdesc"]=>
  array(1) {
    [0]=>
    string(34) "and some experience, coffee & fun."
  }
  ["_titdesc"]=>
  array(1) {
    [0]=>
    string(19) "field_51baf57155c20"
  }
  ["dsq_thread_id"]=>
  array(1) {
    [0]=>
    string(0) ""
  }
}

I want ["titdesc"] value but not able to get what to write in PHP to get ["titdesc"]'s value.

Answer 1

I think you messed up a bit. I'm assuming you're using the ACF plugin because you used the_field().

Have you tried only the_field('titdesc'); if you're in the WordPress loop? Those functions already query values stored in your postmeta table. I'm assuming you have a field called titdesc since you're trying to read it using the_field('titdesc').

If you're not in the loop, you must pass the post ID too, like the_field('titdesc', 2055);.

From what I've noticed, ACF uses two rows per custom field. For you it is:

• titdesc => and some experience, coffee & fun.
• _titdesc => field_51baf57155c20

The first pair of values stores the field name titdesc and the field value and some experience, coffee & fun. and the second pair of values is a reference to the field name's unique ID, which is field_51baf57155c20 here.

As a note, get_field() will return a value and the_field() will echo the value.'

If you want to pass the value in a function, you should use get_field() instead. What you got in your var_dump() output is all meta values stored for that particular post ID.

Answer 2

You should use

echo "<pre>";
print_r($array_name); //$custom_field in your case
echo "</pre>";

That generates a more understandable array dump.

Answer:

 echo $custom_field['titdesc'][0];

would do in your case.

or you can directly get a single meta key using

$titdesc = get_post_meta(2055, 'titdesc',true);
echo $titdesc;
