Unexpected T_VARIABLE in str_replace

[sheppardzwc]

Hey guys,

Ran into an issue earlier, I have debugged this as far as I can and I can't get why I'm having issues. Mind taking a look at it? I'm trying to replace the postbit template with <if condition="$post['noattachdisplay']"> and apparently I'm not doing something right.

Thanks in advance.

Parse error: syntax error, unexpected T_VARIABLE in /home/www/f/includes/class_postbit.php(304) : eval()'d code on line 108

PHP Code:

<?

// showthread_create_postbit

global $vbulletin;
if($vbulletin->options['hide_attach_enable']) {
    $find_begin = '<!-- attachments -->';
    $find_end = '<!-- / attachments -->';
    $replace_begin = '<!-- attachments -->
    <if condition="$post[' . "'" . 'noattachdisplay' . "'" . '">';
    $replace_end = '        <!-- / attachments -->
        </if>';
    $vbulletin->templatecache['postbit'] = str_replace($find_begin, $replace_begin, $vbulletin->templatecache['postbit']);
    $vbulletin->templatecache['postbit'] = str_replace($find_end, $replace_end, $vbulletin->templatecache['postbit']);
}
