hyperlink - Open ad clicking anywhere in wordpress -


i have wordpress site , i'm using script

onclick="<?php if(!isset($_cookie['visited'])){echo"window.open('http://link', '_blank')"; setcookie("visited", "1", time()+3600*24); header("refresh:0");} ?>"

in body line. means i'm using

<body <?php body_class(); ?> onclick="<?php if(!isset($_cookie['visited'])){echo"window.open('http://link', '_blank')"; setcookie("visited", "1", time()+3600*24); header("refresh:0");} ?>">

on header.php file of theme.

but opens link in every click. want open 1 time until refresh page or open new page. how can it. please help. in advance.

greetings.

like setcookie function reference says:

cookies must sent before output script

first solution

you add @ top oh header.php:

<?php $onclick = ''; if(!isset($_cookie['visited'])) {     setcookie('visited', '1', time()+3600*24, cookiepath, cookie_domain);     $onclick = 'onclick="window.open(\'http://link\', \'_blank\')"'; } ?>

update: i've added constants cookiepath , cookie_domain explained here.

and body tag:

<body <?php body_class(); ?> <?php echo $onclick; ?>>

better solution

the prior solution doesn't ensure cookie set before output sent (there characters in 1 of template files before get_header() called, or plugin add something).

instead should add action wordpress hook called before output (like init).

so try adding functions.php file:

add_action('init', 'set_visited_cookie'); function set_visited_cookie() {     if (!isset($_cookie['visited'])) {         setcookie('visited', '1', strtotime('+1 day'), cookiepath, cookie_domain);     } }

as body tag:

<body <?php body_class(); ?> <?php if(!isset($_cookie['visited'])): ?> onclick="window.open('http://link', '_blank')" <?php endif; ?>>

bash - Performing variable substitution in a string -

i have string contains use of variable, , i'd substitute variable's value string. right best have is #!/bin/bash foo='$name; echo bar' name="the name" expanded="$(eval echo "$foo")" echo "$expanded" which has obvious defects: prints the name bar while i'd print the name; echo bar instead of eval can bash's regex matching bash's string replacement: foo='$name; echo bar' name="the name" [[ "$foo" =~ \$([[:alnum:]]+) ]] && s="${!bash_rematch[1]}" && expanded="${foo/\$${bash_rematch[1]}/$s}" echo "$expanded" name; echo bar
