Print Link

[mitch]

Hallo,

is it possible if you open a site as printversion (website.com/Unternehmen&print), and you click on a link, you stay in the print version? What I mean is thet the &print will be added automatically to all links in printversion.


Thanks in advance.

Hi mitch,

What I mean is thet the &print will be added automatically to all links in printversion.

Basically that is possible--however, adding &print to URLs that are not links to CMSimple pages won't make sense, and may be even wrong. If the latter is not of concern, the solution is rather simple. Just add the following function to cmsimple/userfuncs.php:

Code: Select all

function makePrintLinks($content)
{
    return preg_replace('/<a([^>]+)href="([^"]*)"/', '<a$1href="$2&print"', $content);
}

In cmsimple/cms.php change line 420 (the line number varies between different versions) from:

Code: Select all

    content(), '</body>' . "\n" . '</html>' . "\n";

to:

Code: Select all

    makePrintLinks(content()), '</body>' . "\n" . '</html>' . "\n";

Thanks a lot for your efficient answer. Can some pages be defined to be excluded?

Can some pages be defined to be excluded?

Well, you can split function makePrintLinks() in two parts and treat links to these pages differently:

Code: Select all

function makePrintLink($matches)
{
    $url = $matches[2];
    if (strpos($url, 'http') === 0) {
        // let "external" links alone
    } elseif ($url == '?No_print_view') {
        // let certain links alone
    } else {
        // append "&print" to all others
        $url = $url . '&print';
    }
    return '<a' . $matches[1] . 'href="' . $url . '"';
}

function makePrintLinks($content)
{
    return preg_replace_callback('/<a([^>]+)href="([^"]*)"/', 'makePrintLink', $content);
}

Thaks a lot exactly what I'm searching. I will try that...

I have suggested to implement a general solution for CMSimple_XH 1.6.
