Using PHP variable within ACF repeater field

Question

When using ACF (Advanced Custom Fields) repeater fields, the markup should look like this to initiate the loop.

<? if( have_rows('my-repeating-field) ): ?>
<? endif ?>

However, I would like to make this dynamic, meaning I use another PHP variable as part of the if() code, something like as follows:

<? $variable = get_field('my-variable-field'); ?>

<? if( have_rows("'" . $variable . "-repeating-field" . "'") ): ?>
<? endif ?>

However, this is not working. Is there a way I can do this with ACF/PHP? Seems pretty simple to me?

did you checked $variable has any value or not? you can try $row_field = $variable . '-repeating-field'; and then use var_dump to check if it has corrected value or not. then if it is correct try if(have_rows($row_field)... — Ali Qorbani

Yes it outputs as expected, but still doesn't work. I.e <? $variable . '-repeating-field' = variablevalue-repeating-field ?> — dungey_140

Is "variablevalue-repeating-field" an ACF repeater field name? — suspectus

You're quoting the string in a weird way, so the value will have single quotes in it... have_rows($variable . '-repeating-field') should be enough — ɴᴀᴛᴇ ᴅᴇᴠ

The problem is that you're concatenating the string in a way which would cause the end value being passed to have_rows to have quotes inside of it. You only need to concatenate the value and the end of the string, and that should be enough.

have_rows($variable . '-repeating-field')
