Generate XML using sub_fields recursively
-
Hi!
I have the following fields and subfields:
-field_1->value_1 -field_2-> --subfield_1->value_2 --subfield_2->value_3 -field_3->subfield_3->subfield_4->subfield_5->value_4 ... etc.I need to generate XML using names of fields and subfields and values like this:
<field_1>value_1</field_1> <field_2> <subfield_1>value_2</subfield_1> <subfield_2>value_3</subfield_2> </field_2> <field_3> <subfield_3> <subfield_4> <subfield_5> value_4 </subfield_5> </subfield_4> </subfield_3> </field_3>Here is my code:
<?php $args = array( 'post_type' => 'kvartiry', ); $objects = new WP_Query($args); while ($objects -> have_posts()) : $objects -> the_post(); // $objectID = $post->ID; $fields = get_field_objects(); //var_dump( $fields ); if($fields) { foreach($fields as $field_name => $field) { echo '<' . $field['name'] . '>' . PHP_EOL; while(has_sub_field($field['name'])): foreach($field['sub_fields'] as $k => $v) { echo '<' . $v['name']. '>' . get_sub_field($v['name']) . '</' . $v['name']. '>' . PHP_EOL; } endwhile; echo '</' . $field['name'] . '>' . PHP_EOL; } } endwhile; wp_reset_postdata(); ?>Here is the output:
<rooms> </rooms> <floor> </floor> <ololo> <lola>qwerty</lola> <lola>zaq</lola> </ololo> <azaza> <zaza>13777777</zaza> <zaza>44444555</zaza> </azaza> <rooms> </rooms> <floor> </floor> <ololo> <lola>777</lola> </ololo> <azaza> </azaza> <level_1> <level_2>Array</level_2> </level_1> <rooms> </rooms> <floor> </floor> <rooms> </rooms> <floor> </floor>Here is the output with var_dump( $fields ) uncommented:

Hi @bart-gopnik
In this case, you need to create a function to loop through the returned fields and its values. Here’s an example how to do it:
// Create function that will loop through the array function print_array_value($value){ if( is_array($value) ){ foreach( $value as $k => $the_value ){ echo '<' . $k . '>' . PHP_EOL; print_array_value($the_value); echo '</' . $k . '>' . PHP_EOL; } } else { echo $value . PHP_EOL; } } // Loop through the fields here foreach($fields as $field){ echo '<' . $field['name'] . '>' . PHP_EOL; // Check if this is a repeater or not print_array_value($field['value']); echo '</' . $field['name'] . '>' . PHP_EOL; }Because this is more related to PHP than ACF, kindly get in touch with PHP community for more support.
I hope this helps 🙂

Thanks for your code! But unfortunately it produce the following XML:
<rooms> 1 </rooms> <floor> 2 </floor> <azaza> <0> <zaza> 556 </zaza> </0> <1> <zaza> 557 </zaza> </1> </azaza> <ololo> <0> <lola> 558 </lola> </0> </ololo> <level_1> <0> <level_2> <0> <level_3> 559 </level_3> </0> <1> <level_3> 560 </level_3> </1> </level_2> </0> </level_1>instead of:
<rooms> 1 </rooms> <floor> 2 </floor> <azaza> <zaza> 556 </zaza> <zaza> 557 </zaza> </azaza> <ololo> <lola> 558 </lola> </ololo> <level_1> <level_2> <level_3> 559 </level_3> <level_3> 560 </level_3> </level_2> </level_1>What should I do to disable unnecessary
<0>,<1>, etc. tags? -
Hi @bart-gopnik
The easiest way would be checking if the current key is a number or not like this:
// Create function that will loop through the array function print_array_value($value){ if( is_array($value) ){ foreach( $value as $k => $the_value ){ if( is_numeric($k) ){echo '<' . $k . '>' . PHP_EOL;} print_array_value($the_value); if( is_numeric($k) ){echo '</' . $k . '>' . PHP_EOL;} } } else { echo $value . PHP_EOL; } } foreach($fields as $field){ echo '<' . $field['name'] . '>' . PHP_EOL; // Check if this is a repeater or not print_array_value($field['value']); echo '</' . $field['name'] . '>' . PHP_EOL; }I hope this makes sense 🙂

What if need use numeric names for subfileds?
<level_1> <123> <777> 559 </777> <777> 560 </777> </123> </level_1> -
BTW,
is_numeric($k)doesn’t work. Seems it should beis_string($k)or!is_numeric($k). -
Hi @bart-gopnik
The numbers you saw is the index of the repeater row. It’s there to group the rows to avoid confusion while processing it (imagine you have multiple fields in a single row).
If you want to get rid the index numbers and you want to have numbers as the subfield name, then you need another method to do that. Unfortunately, this is more related to PHP instead of ACF. Kindly get in touch with PHP community for further support.
Also, yes, It seems I missed the exclamation point. The correct code is
!is_numeric($k). I’m sorry about that.I hope this makes sense 🙂
