Comma-separated array values

I’m not advanced with PHP and am having problems setting up array values to display with comma-separation instead of list items as in the documentation.

This is what I have:

$values = get_field('fieldname');
	if($values)			
	{ foreach($values as $value)
		{
		echo  $value ;
		}
	}

I’ve tried explode but am having trouble getting it to work. Thanks for any assistance.

Can you provide a sample of the get_field('fieldname'); data? Here’s a quick debug snippet to see what the field holds:

echo '<pre>'.print_r(get_field('fieldname'), true).'</pre>';

If you already have a comma-separated value and want to convert it to an array, try this little snippet out:

$values = explode(',', get_field('fieldname'));
if( count($values)){
    foreach($values as $value){
        echo trim($value);
    }
}

This snippet should work with a text string that looks something like one,two, three four, five-, six and should output this: onetwothreefourfivesix.

However, I have a feeling that you already have an array as provided by get_field('fieldname'), so if that’s the case then you don’t need to explode at all, just loop with a foreach() and output with something like echo $value.', ';. A snippet like this might look like:

$values = get_field('fieldname&#039);
if( count($values)){
    foreach($values as $k=>$value){
        if($k) echo ', ';
        echo $value;
    }
}

In this example, $k is a counter that lets us know what item number we are currently working with. During the first loop, $k will be 0 so no comma will be printed.

This worked great! This is what I used:

$values = get_field('myfieldname');
if( count($values)){
    foreach($values as $k=>$value){
        if($k) echo ', ';
        echo $value;
    }
}
