Dump All Custom Fields

WordPress has a built in function, the_meta(), for outputting all custom fields. But this function is limited in that it doesn't always output all of them. For example, it misses custom fields added by plugins which begin with an _ underscore.

This bit of code uses an alternate function, get_post_custom() which will return all of them, and display all values. Good for debugging.

<h3>All Post Meta</h3>

<?php $getPostCustom=get_post_custom(); // Get all the data ?>

<?php
    foreach($getPostCustom as $name=>$value) {

        echo "<strong>".$name."</strong>"."  =>  ";

        foreach($value as $nameAr=>$valueAr) {
                echo "<br />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;";
                echo $nameAr."  =>  ";
                echo var_dump($valueAr);
        }

        echo "<br /><br />";

    }
?>

  1. Ah just what I’ve been looking for. Easy to customize into what you want like a list pulling out all image URLs.

Posting Code

  • Use Markdown, and it will escape the code for you, like `<div class="cool">`.
  • Use triple-backticks for blocks of code.
    ``` 
    <div>
      <h1>multi-line block of code</h1>
      <span>be cool yo.</span>
    </div>
    ```
  • Otherwise, escape your code, like <code>&lt;div class="cool"&gt;</code>. Markdown is just easier though.
