Re: Link to printer-friendly CSS
Okay, i worked it out. You do not even need a plugin for this.
- prepare a stylesheet in TXP and call it print
- add a link to the article:
<p><a href="?print=1" target="_blank">Printerfriendly Version</a></p> - add the following code in the head of your html template
<code><?php $style = “<txp:css />”; // default style
if (isset($_GET[‘print’]) && $_GET[‘print’] == ‘1’) {
$style=”/path/to/textpattern/css.php?n=print”;
}
echo “<link rel=\“stylesheet\” href=\”$style\” type=\“text/css\” media=\“all\” />\n
<link rel=\“stylesheet\” href=\”/path/to/textpattern/css.php?n=print\” type=\“text/css\” media=\“print\” />\n”; ?></code>
Many thanks to trailgirl!

Re: Link to printer-friendly CSS
Hi.
Please, can someone explain me the following code? (it’s the same as above, but I paste it again so it displays right)
<?php $style = "<txp:css />"; // default style
if (isset($_GET['print']) && $_GET['print'] == '1') {
$style="/path/to/textpattern/css.php?n=print";
}
echo "<link rel=\"stylesheet\" href=\"$style\" type=\"text/css\" media=\"all\" />\n
<link rel=\"stylesheet\" href=\"/path/to/textpattern/css.php?n=print\" type=\"text/css\" media=\"print\" />\n"; ?>I don’t get why it sets the $style = <txp:css />, when then, if the conditional is true, the value is replaced, and then, if I’m getting it right, finally will echo a <link /> to the same stylesheet (the same vaule for href, I mean)
If I’m understanding it right, why it isn’t just this:
<?php
if (isset($_GET['print']) && $_GET['print'] == '1') {
echo "<link rel=\"stylesheet\" href=\"/path/to/textpattern/css.php?n=print\" type=\"text/css\" media=\"print\" />\n"
}; ?>Thanks in advance.

Re: Link to printer-friendly CSS
In the meanwhile, Gocom (thanks, Go!) helped me at #textpattern on irc.freenode.net and suggested me this code:
echo (gps('print')) ?
'<link rel="stylesheet" href="'.css(array('n' => 'print')).'" media="all" />' :
'<link rel="stylesheet" href="'.css(array()).'" media="all" />';I haven’t tested it yet but I share it here for two reasons: for others who can also need it, and for having an explanation about this one snippet too.

Re: Link to printer-friendly CSS
echo ((gps('print')) ?
'<link rel="stylesheet" href="'.css(array('n' => 'print')).'" media="all" />'.n :
'<link rel="stylesheet" href="'.css(array()).'" media="all" />'.n).
'<link rel="stylesheet" href="'.css(array('n' => 'print')).'" media="print" />';That is better, but your right, that code you pasted doesn’t even really work. And yeah, you have misunderstood the meaning of it: It should make the page look printable, same as it would be when it is printed, but in the browser. Also, it’s quite pointless to post this thread as this is way old.
And the code you “why it isn’t just this:” is just because that snippets has zero meaning. Nada. Printable stylesheet in conditionals? That is only for printers media="print". So user must click link and then print? Wow, amazing navigation, nope, it was not the idea of the original snippet as I explained.
Isn’t it nice to view page like it would look in A4? Yeah, it is. And that is what it could do. To access the script, use <a href="?print=print-this-page">Print me</a> or something else.

Re: Link to printer-friendly CSS
Thanks again, Gocom.
It took me some minutes to understand that your writing (condition ? true, do this : false, do this) was one of those ways of writing conditionals.
And, finally, this is the code I was looking for:
<txp:php>
echo ((gps('print')) ?
'<link rel="stylesheet" href="<txp:rvm_css n="print" />" media="all" /><!-- true -->'.n :
'<link rel="stylesheet" href="<txp:rvm_css n="print" />" media="print" /><!-- false -->');
</txp:php>Just wanted “print.css” with different media types, because all other stylesheet are linked already above, outside the print conditional.
Also, just to know, could chs_if_urlvar have done the work too, right? If i understand correctly, it is also useful to evalute ?variable=value on URLs.
