How is the data saved?
The repeater field saves all it’s data in the wp_postmeta table. If your repeater field is called “gallery” and contains 2 sub fields called “image” and “description”, this would be the database structure of 2 rows of data:
// meta_key meta_value
gallery 2 // number of rows
gallery_0_image 6 // sub field value
gallery_0_description "some text" // sub field value
gallery_1_image 7 // sub field value
gallery_1_description "some text" // sub field value
that means:
try this:
$post->repeater_0_subfield //for first row
$post->repeater_1_subfield //for second row
...
or create a foreach or a while loop: described here
