get_field（）返回错误的数据

问题描述：

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.

我正在使用ACF转发器字段，我正在尝试编写一个计算转发器行数的函数。即使转发器中的行数为0或大于0，该函数也会返回1. 有人帮我修复此问题吗？ p>

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

答

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
