I want to let users add a new row in a repeater field.
One row contains an image field and two text fields.

The idea is to have an user generated gallery. The gallery works good so far. As admin i can add images endlessly. Now its time to let users add some images.

i found an article:
http://www.jqui.net/wordpress/acf-upload-image-made-easy/
and a function from the docs:
http://www.advancedcustomfields.com/resources/update_sub_field/

But those approaches just update an existing field. How about adding a new row??

kind regards!

alright. i managed it! i use a function to upload the image to the media list first:
http://goldenapplesdesign.com/2010/07/03/front-end-file-uploads-in-wordpress/

i read the existing rows first and then use the attachment id from the function above:

<form action="<?php the_permalink(); ?>" method="POST" enctype="multipart/form-data">
	<input type="file" name="imageupload"/>
	<input type="hidden" name="userid" value="<?php echo $current_user->ID;?>" />
	<input type="hidden" name="username" value="<?php echo $current_user->display_name;?>" />
	<input type="submit"/>
</form>
<?php
	foreach ($_FILES as $file => $array) {
		$image = insert_attachment($file,$post->ID); //upload image and returns the id
	}
	if( have_rows('galerie') ){
		$gallery = get_field( 'gallery' );
	} else {
		$gallery = array();
	}
	
	// add to existing array
	$gallery[] = array(
		'bild'			=> $image,
		'nutzerid'		=> $_POST["userid"],
		'nutzername'	=> $_POST["username"],
		'freigeben'		=> ""
	);
	// save new array
	update_field("field_53e0e20e2cc16", $gallery, $post->ID);
?>

you can see my acf setup in the attachment. maybe someone has ideas to simply things?!
