Title: Can’t get data from array Last modified: August 19, 2016 --- # Can’t get data from array * Resolved [Deniska](https://wordpress.org/support/users/deniska/) * (@deniska) * [16 years, 2 months ago](https://wordpress.org/support/topic/cant-get-data-from-array/) * I want to get data from array. This code is working: * ``` add_filter( 'single_template', 'my_template' ); function my_template( $template ) { $catid = array(4,5,6); if ( in_category($catid) ) $template = locate_template( array( 'single-port.php' ) ); return $template; } ``` * but I try to set data like this : * ``` add_filter( 'single_template', 'my_template' ); function my_template( $template ) { $catid = array(get_option('imp_cat')); if ( in_category($catid) ) $template = locate_template( array( 'single-port.php' ) ); return $template; } ``` * Last example doesnt work. Categories ID doesn’t received.What I need to do? Thanks!

I’m put this id’s in my theme options. `imp_cat` thats a options textfield id. In this textfield I put categories ID’s -4,5,6.
