How can I get get all Texts form Flexible Contents and nested Repeater of a post in an sting for as post summary?

I have the function below, that works find for all ACF Fields but not for Flexible Content Fields. Some flexible fields have nested repeater fields.

	// function to get the conntent of all custom fileds fron array to one string
  function get_fields_content($include_fields, $fields) {
	 	
	 	
	 	// loop the fields and add all content to one string
		if( $fields ) {
			foreach( $fields as $field_name => $field ):
					$fieldname = $field['name']; // get the cutom field name for the filter
					$fieldvalue = $field['value']; // get the content of the field	
					
					// filter by cutomfield from array and if value has content	
					if ((in_array($fieldname, $include_fields) && ($fieldvalue))) { 
						// add too $all a spache and a line break behind each field and add the html-stripped content from the next field
						if ( !is_array($fieldvalue)) {
							$all = $all . strip_tags($fieldvalue) . ' '; 
						}	
					}
								
			endforeach;					
				
			$all_content =  $all;
		}
	         
    return $all_content;
  }

$fields = get_field_objects(); 
$include_fields = array(
	'field_1',
	'field_2',
	'field_3',
	'field_4',
	'field_5',
);

Hi @bluesky

You can always check the structure of a flexible content like this:

var_dump( get_field('flexible_content_field_name') );

So for a flexible content, you can do it like this:

foreach( $fieldvalue as $row ){
    
    foreach( $row as $k => $column){
        
        if( $k !== 'acf_fc_layout' && !is_array($column) && !is_object($column) ){
            $all .= strip_tags($column) . ' ';
        }
        
    }
    
}

I hope this helps 🙂

Thanks!

But it is actually not perfect, because this includes all sub-content-fields content an not only from field in the include_fields array…

how can I add an
in_array($fieldname, $include_fields)
in your code?

Hi @bluesky

In this case, you need to get the current field name from the column key like this:

foreach( $fieldvalue as $row ){
    
    foreach( $row as $k => $column){
        
        if( $k !== 'acf_fc_layout' && !is_array($column) && !is_object($column) ){

            // get the current field name
            $current_field_name = str_replace($row['acf_fc_layout'].'_', '', $k);

            // check if in array
            if( in_array($current_field_name, $include_fields) ){
                $all .= strip_tags($column) . ' ';
            }
        }
        
    }
    
}

I hope this helps 🙂

Perfect, thanx!

this is mit current “final” function:

	// function to get the conntent of all custom fileds fron array to one string ---------------------------------------------------------------------------------------
  function get_fields_content($include_fields, $fields) {
	 	
	 	
	 	// loop the fields and add all content to one string
		if( $fields ) {

			foreach( $fields as $field_name => $field ):
					$fieldname = $field['name']; // get the cutom field name for the filter
					$fieldvalue = $field['value']; // get the content of the field	
					
					// filter by cutomfield from array and if value has content	
					if ((in_array($fieldname, $include_fields) && ($fieldvalue))) { 
						// add too $content a spache and a line break behind each field and add the html-stripped content from the next field
						if ( !is_array($fieldvalue)) {
							$content .=  strip_tags($fieldvalue) . ' '; 
						}	else {
						
							// for the subfields if acf flexible content layouts ----------------------------
							// https://support.advancedcustomfields.com/forums/topic/get-all-texts-form-flexible-contents-and-nested-repeater/
							foreach( $fieldvalue as $row ){
	    
									foreach( $row as $k => $column){
	        
										if( $k !== 'acf_fc_layout' && !is_array($column) && !is_object($column) ){
	
											// get the current field name
											$current_field_name = str_replace($row['acf_fc_layout'].'_', '', $k);
	
												// check if in array
												if( in_array($current_field_name, $include_fields) ){
													$content .= strip_tags($column) . ' ';
	            							}
											}
	        
			  							}
									}
								// end subfields ----------------------
						}
					}
								
			endforeach;					
		}
	         
    return $content;
  }

  // -------------------------------------------------------------------------

and to get the fields and call the function:

	
$fields = get_field_objects(); 
			$include_fields_content = array('acf_field_1' , 'acf_field_2' , 'acf_field_3);
			$content = get_fields_content($include_fields_content, $fields);
