str_replace problem

[emath]

thats looks very helpful though it still not what i need .

i want to change the <div> tag to <div id="thread_active_users">

actually,

the code in the SHOWTHREAD template is :

			<div>
				<p>

and i want to change it with :

                        <!-- Refresh Button -->
							<vb:if condition="$vbulletin->options[\'active_users_onoff\']">
							<button onclick="showUsers()" type="button" style="float:left;"> {vb:rawphrase refresh_button} </button>
							</vb:if>
				<div id="thread_active_users">
				<p>

so i can use what u did and do something like that :

PHP Code:

$find = '<div>' . "\n" . '                <p>';
$replace = "                        <!-- Refresh Button -->\n";
if ($vbulletin->options['active_users_onoff'])
   $replace .= '<button onclick="showUsers()" type="button" style="float:left;"> ' . htmlspecialchars_uni($vbphrase['refresh_button']) . '</button>' . '<div id="thread_active_users">' . "\n" . '                <p>';
// $replace .= $find;
$vbulletin->templatecache['SHOWTHREAD'] = str_replace($find, $replace, $vbulletin->templatecache['SHOWTHREAD']); 


though this on the hook showthread_complete doesnt work.

how can i find the right text to find? the compiled version of SHOWTHREAD doesnt help at all...

this is the right part of it i think, but it tells me nothing :

' . vB_Template_Runtime::parsePhrase("users_browsing_this_thread") . '

' . vB_Template_Runtime::parsePhrase("users_currently_browsing_x_y_z", '' . $totalonline . '', '' . $numberregistered . '', '' . $numberguest . '') . '
