get_field（）返回错误的数据

Question

I am using ACF repeater fields and I am trying to write a function which counts the number of rows of the repeater. The function returns 1 even if the number of rows in a repeater are 0 or more than 0. Can someone help me to fix this ?

$rows = get_field('sub_seminars');
$row_count = count($rows);
echo count($row_count);

A var_dump also returns int(1) even if the number of rows in a repeater are 0 or more than 0.

Answer 1

Let's have a look at your code:

$rows = get_field('sub_seminars');
$row_count = count($rows);  //returning some digit
echo count($row_count);  //counting the returned digit

You are double counting the returned count and that is why it is returning 1. Try this:

$rows = get_field('sub_seminars');
$row_count = count($rows);     //will return a digit
echo $row_count;  //echo the count
