Conditional statement problem (expects parameter)

  • Hi,

    I am using Conditional statement (Checkbox rvalue is an array) function to get two outputs. But if “None” checkbox is ticket I get this error:

    “Warning: in_array() expects parameter 2 to be array, string given in…”

    How can I do an “if empty” check or otherwise write it properly?

    This is my code:

    <?php if( in_array( 'Materialet er tilgængeligt til download', get_field('materiale') ) ) {echo '<a href="' . get_field('download') . '" target="_blank" class="readmore">Download PDF →</a>';}?>
    
    <?php if( in_array( 'Materialet er tilgængeligt som eksternt link', get_field('materiale') ) ) {echo '<a href="' . get_field('link') . '" target="_blank" class="readmore" >Eksternt link →</a>';}?>

    Thanks

  • Hi @cheyens
    I would first test the value of your get_field to see why the error is showing in the first place.

    
    <?php 
    
    echo '<pre>';
    	var_dump(get_field('materiale'));
    echo '</pre>';
    die;
     ?>
    

    What do you get?

  • Hi,

    I get this:

    string(0) ""

  • Looks like there is no value saved for the field.

    This means your in_array function will fail due to the wrong variable type.

    Perhaps you need to also compare the value like so:

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