Better "Preview" for templates in the CP

This is a very quick hack that enhaces the "Preview" feature in the Template Editor. Currently I find the preview to be useless, I can also see funky colors and odd tables.
With this hack, you will get a slightly better idea of how the template will really look like, because all the {replacement} variables will be replaced with their real value.

If you have Mutt's "Advanced Template Editor" hack installed, please follow the directions in this post:

Thanks Mutt!

In template.php replace:

PHP Code:

function dotemplatejavascript() {

    $buttonextra="
<SCRIPT LANGUAGE=\"JavaScript\">
function displayHTML() {
var inf = document.name.template.value;
win = window.open(\", \", 'popup', 'toolbar = no, status = no, scrollbars=yes'); 


With this:

PHP Code:

function dotemplatejavascript() {
    global $DB_site, $bburl;

    $replacementsetid = 1;    ### Change me to use a different replacement set!

    $vars = $DB_site->query("
        SELECT findword,replaceword FROM replacement
        WHERE replacementsetid IN(-1,'$replacementsetid')
        ORDER BY replacementsetid DESC,replacementid DESC
    ");
    while ($var=$DB_site->fetch_array($vars)) {
        if ($var['findword']!="") {
            if ($var['findword'] == '{images[i][/i]folder}'
                or $var['findword'] == '{titl[i][/i]eimage}'
                or $var['findword'] == '{newthr[i][/i]eadimage}'
                or $var['findword'] == '{closed[i][/i]threadimage}') {
                $var['replaceword'] = $bburl . '/' . $var['replaceword'];
            }
            $varinf .= 'inf = replace(inf,"'.addslashes($var['findword']).'","'.addslashes($var['replaceword']).'");
';
        }
    }

    $buttonextra="
<SCRIPT LANGUAGE=\"JavaScript\">

function replace(string,text,by) {
// Replaces text with by in string
    var strLength = string.length, txtLength = text.length;
    if ((strLength == 0) || (txtLength == 0)) return string;

    var i = string.indexOf(text);
    if ((!i) && (text != string.substring(0,txtLength))) return string;
    if (i == -1) return string;

    var newstr = string.substring(0,i) + by;

    if (i+txtLength < strLength)
        newstr += replace(string.substring(i+txtLength,strLength),text,by);

    return newstr;
}

function displayHTML() {
var inf = document.name.template.value;
$varinf
win = window.open(\", \", 'popup', 'toolbar=no,status=no,scrollbars=yes,width=800,height=600'); 


You can change the $replacementsetid if you want:

	$replacementsetid = 1;	### Change me to use a different replacement set!

Enjoy!

Chen,

I uninstalled the hack and reinstalled it and I get the same javascript errors when I try to use either FIND or PREVIEW. When I uninstalled it, everything went back to working the old way. I can use find and preview now with no errors. Is there any way that I can get this working somehow? It looks like exactly what I need. I'd like to get it working if possible.
