Wordpress - Custom Fields and Meta Data

Given the code snippet:

$value = get_post_meta(10, 'price', true);
echo $value;

What will be the output if the custom field 'price' for post ID 10 is set to '25.99'?

AError: Undefined variable

BArray

CNULL

D25.99

Step-by-Step Solution

Solution:

Step 1: Understand get_post_meta() with single=true
When the third parameter is true, get_post_meta() returns a single value as a string, not an array.
Step 2: Check the stored value for 'price'
The custom field 'price' for post ID 10 is '25.99', so echoing $value outputs '25.99'.
Final Answer:
25.99 -> Option D
Quick Check:
Single meta value output = 25.99 [OK]

Quick Trick: Use true to get single value, not array [OK]
