Problem with Array (expects parameter 2 to be array)

[Cheyens]

Hi,

This works as long one or both Checkboxes are checked:

<?php if( in_array( 'Red', get_field('materiale') ) ) {echo '<a href="' . get_field('download') . '" target="_blank" class="readmore">Red →</a>';}?> <?php if( in_array( 'Blue', get_field('materiale') ) ) {echo '<a href="' . get_field('link') . '" target="_blank" class="readmore" >Blue →</a>';}?>

But if "NONE" are checked I get this error:
Warning: in_array() expects parameter 2 to be array, string given in

How do I write this up properly?

Thanks

Maybe this needs further explanation:

I'm using Advanced Custom Fields Plugin with WordPress and this:

/*
* Conditional statement (Checkbox rvalue is an array)
*/

if( in_array( 'red', get_field('field_name') ) )
{
    //...
}

But how do I make two if( in_array without getting the "Problem with Array (expects parameter 2 to be array) error if none of the two checkboxes where ticked? How can it be "empty" without creating an error.

Sorry...

It *looks* like get_field can return an array or a string depending on the field type. You might try short circuiting your if

$ret = get_field('field_name');

if(is_array($ret) && in_array('red', $ret))
   // if path taken
else
   // else path taken

Hi,

I've managed to solve it like this:

<?php 
if( get_field('materiale') )
{
	if( in_array( 'Red', get_field('materiale') ) )
	{
		echo '<a href="' . get_field('download') . '" target="_blank" class="readmore">Red →</a>';
	}
}
?>
