I have a repeater named
resources with 8 fields. The first field is a radio field with three options. Depending on your choice, a subset of the remaining 7 fields are shown. For context, these are resources for a non-profit web site and may include links to internal pages/posts/cpt (via relationship field), external links (text field) or internal documents (file field). On my template, I loop through the rows and need to switch the HTML output (and sub_field() calls) depending on what type of content it is, as indicated by the radio field value.
The radio field, called “resource-type” has these values
internal : Internal Link external : External Resource doc : Document
In my test content I have 4 rows:
This code, outputs what I would expect:
<?php if( have_rows('resources') ): while ( have_rows('resources') ) : the_row(); $type = get_sub_field('resource_type'); echo "<h3>Type: " . $type . " </h3>"; endwhile; endif; ?>
Type: internal Type: external Type: doc Type: internal
But, after reading “The the_row function also returns the row data as an array if you wish to store it as a variable and use it.” on http://www.advancedcustomfields.com/resources/functions/have_rows/#notes I thought that this would output the same thing:
<?php if( have_rows('resources') ): while ( have_rows('resources') ) : the_row(); $row = the_row(); $type = $row['resource_type']; echo "<h3>Type: " . $type . " </h3>"; endwhile; endif; ?>
But it’s only outputting:
Type: external Type: internal
What am I missing?
The issue is that you are using
the_row twice within the loop!
Only use it once per loop like so:
<?php if( have_rows('resources') ): while ( have_rows('resources') ) : $row = the_row(); $type = $row['resource_type']; echo "<h3>Type: " . $type . " </h3>"; endwhile; endif; ?>
Just in case someone stumbles across this in 2017 onwards: it turns out that contrary to what is stated in the docs for get_row() and the_row(), both functions return arrays keyed by field internal names and not field user defined names. So you will get:
Array ( [field_5855ac26cb153] => 'John' [field_5855ac26cb154] => 'Smith' [field_5855ac26cb155] => 31 )
Array ( [name] => 'John' [surname] => 'Smith' [age] => 31 )
…as the docs would have you believe. This makes both functions more or less useless for the end user. It has been raised with support back in September that either both functions should return arrays keyed by field names or the docs should be changed as they are misleading. Neither has been done.
As an update to the previous comment since 5.3.3 of ACF Pro you can pass a
true bool to the_row / get_row i.e.
This will output your keynames as expected and originally explained in previous comments
This is explained in the docs found here: https://www.advancedcustomfields.com/resources/get_row/
