> I tried with litespeed_buffer_after but it does not work
Could you please explain a bit what or how exactly did you do ?
Here is my code:
add_action( 'template_redirect', function () {
ob_start( function ( $output ) {
$nonces = [];
$output = preg_replace_callback( '#<script.*?\>#', function ( $matches ) use ( &$nonces ) {
$nonce = wp_create_nonce( $matches[0] );
$nonces[] = $nonce;
return str_replace( '<script', "<script nonce='{$nonce}'", $matches[0] );
}, $output );
$output = preg_replace_callback( '#<style.*?\>#', function ( $matches ) use ( &$nonces ) {
$nonce = wp_create_nonce( $matches[0] );
$nonces[] = $nonce;
return str_replace( '<style', "<style nonce='{$nonce}'", $matches[0] );
}, $output );
$nonces_csp = array_reduce( $nonces, function ( $header, $nonce ) {
return "{$header} 'nonce-{$nonce}'";
}, '' );
header( sprintf( "Content-Security-Policy: base-uri 'self' data:; object-src 'none'; script-src https:%s 'strict-dynamic'", $nonces_csp ) );
return $output;
} );
} );
So I tried to do the same with litespeed_buffer_after:
add_action( 'litespeed_buffer_after', function ($content) {…
But it does not work.
Maybe it’s not the way the hook should be used, so I ask you…

the logic looks right , ish
the litespeed_buffer_after is used to modify the html output before send to user
if you just do a simple string replace on some or any text, does it work ? like
function lscwp_test_check( $content ) {
return str_replace( 'something1', 'something2', $content );
}
add_filter( 'litespeed_buffer_after', 'lscwp_test_check', 0);
Test code works perfectly.
But with my code snippet, I just had a blanck empty page. I just removed the ob_start function – now my code works perfectly.
Can be used to have a secured CSP.
Thanks for help!
Yes! It works perfectly. ob_start was ΤHE problem!
