The get_sub_field()
function in Advanced Custom Fields (ACF) is used to retrieve the value of a sub field within a repeater field. However, there are certain cases where get_sub_field()
may not work as expected. Here’s a code snippet that can help you troubleshoot and fix the issue:
if( have_rows('repeater_field_name') ) {
while( have_rows('repeater_field_name') ) {
the_row();
// Get the sub field value using get_sub_field()
$sub_field_value = get_sub_field('sub_field_name');
// Check if the sub field value exists
if( $sub_field_value ) {
// Do something with the sub field value
echo $sub_field_value;
}
}
}
In this code snippet, we first check if there are rows available in the repeater field using the have_rows()
function. Then, we loop through each row using the while
loop and call the the_row()
function to set up the row data. Inside the loop, we use get_sub_field()
to retrieve the value of the sub field.
To ensure that get_sub_field()
works correctly, make sure you have the correct names for the repeater field and the sub field. Replace 'repeater_field_name'
with the actual name of your repeater field and 'sub_field_name'
with the actual name of your sub field.
By using this code snippet, you can effectively retrieve and display the values of sub fields within a repeater field using ACF in WordPress.
