WordPress: update_option, don't update empty options?

Hey Guys,

I am storing the entire $_POST array in my options panel, but it stores the empty fields too (dynamically generated). How do I filter out the empty value and not include them?

This doesn’t work

<?php foreach($_POST['eirepanel_inline_ads_options_name'] as                                         $post_eirepanel_inline_ads_options_name):
if(empty($post_eirepanel_inline_ads_options_name)): 
echo 'empty';
else: 
update_option('eirepanel_inline_ads_options', $_POST);
$eirepanel_inline_ads_options = get_option('eirepanel_inline_ads_options');
endif; 
endforeach;
?>

if(trim($post_eirepanel_inline_ads_options_name)==""):
echo "empty";

This is how I do it

Thanks for the reply mate but I am storing the POST array so your solution would not work

You should loop though the $_POST array and create a new array with the only values you need… make a print_r($_POST); to see how many things that you don’t need are in it.

I guess ‘empty’ will not work. Did you try ‘isset’ instead? If not working, comparing it with an empty string ( if( $_POST[ ‘var_name’ ] != ’’ ) ) should work.

@RedHenry,

It is not easy to give you the best direction if we can’t see the full code, we don’t know how you write your form elements…

If you are familiar with debugging, you can try ParkerAndKent’s suggestion, print_r($_POST); will output all arrays that will help you analyze your problem. you can also try to use print_r($_POST[‘eirepanel_inline_ads_options_name’]) and we can see the stored value…

you can also send your full code to me through my Profile page and i would love to check it
