How best to talk about Google Fonts?

Chairman, have we still got a quorum? Chairman?!

Well, we really like to explain some topics by launching into it and applying it, so we came at this “applying it” from two angles …

  1. proof of concept … just call me “A Cute”
  2. temporary CSS option for the blog you are reading … my name is “Ob Tuse”

This useful “application of Google Fonts” template webpage, if you will … thanks … inspired me to write the test_gf.php‘s proof of concept shown below …

… where, if you glean some good Google Font Family names visiting this webpage, where a lot of the online world’s geniuses with fonts have gathered to assemble this online repository of font “goodies” free for us all to access … thanks, heaps!

To see it in action with actual webpages we extend the logic of WordPress Temporary User CSS Primer Tutorial‘s menu driven blog webpage code to allow your temporarily applied CSS amount to the name of one of those Google Font Family names, to which we extend the thinking to the two step application of the functionality that goes (to good ol’ header.php of the WordPress TwentyTen theme … as per usual) …

  1. call the Google Font with <head> and </head> as per the additional (PHP code snippet change) …

    if (isset($_GET['cssextra'])) {
    if ($_GET['cssextra'] != '' && strpos(urldecode($_GET['cssextra']), "{") === false) {
    echo "\n<link href='//fonts.googleapis.com/css?family=" . str_replace('+',' ',urldecode($_GET['cssextra'])) . "' rel='stylesheet'>\n";
    }
    if ($_GET['ourcss'] != '' && strpos(urldecode($_GET['ourcss']), "{") === false) {
    echo "\n<link href='//fonts.googleapis.com/css?family=" . str_replace('+',' ',urldecode($_GET['ourcss'])) . "' rel='stylesheet'>\n";
    }
    }
    ?>
    <style>
  2. change code checking for web address (PHP $_GET[]) arguments and/or PHP $_SESSION variables changed as per (PHP code snippet change) …

    if (isset($_SESSION['ourcss'])) {
    echo str_replace('<' . 'style>','',str_replace('<' . '/style>','',$_SESSION['ourcss']));
    } else if (file_exists("localcss_" . my_t_d_server_remote_addr() . ".yzy")) {
    $lcss = str_replace('<' . 'style>','',str_replace('<' . '/style>','',file_get_contents(("localcss_" . my_t_d_server_remote_addr() . ".yzy"))));
    $_SESSION['ourcss'] = $lcss;
    echo $lcss;
    unlink("localcss_" . my_t_d_server_remote_addr() . ".yzy");
    } else if (isset($_GET['cssask'])) {
    } else if (isset($_GET['ourcss'])) {
    if ($_GET['ourcss'] != '' && strpos(urldecode($_GET['ourcss']), "{") === false) {
    $_SESSION['ourcss'] = str_replace('<' . 'style>','',str_replace('<' . '/style>','', ' body { font-family:' . str_replace('+',' ',urldecode($_GET['ourcss'])) . '; }' ));
    echo $_SESSION['ourcss'];
    } else {
    $_SESSION['ourcss'] = str_replace('<' . 'style>','',str_replace('<' . '/style>','',urldecode($_GET['ourcss'])));
    echo $_SESSION['ourcss'];
    }
    } else if (isset($_GET['cssextra'])) {
    if ($_GET['cssextra'] != '' && strpos(urldecode($_GET['cssextra']), "{") === false) {
    $_SESSION['ourcss'] = str_replace('<' . 'style>','',str_replace('<' . '/style>','', ' body { font-family:' . str_replace('+',' ',urldecode($_GET['cssextra'])) . '; }' ));
    echo $_SESSION['ourcss'];
    } else {
    $_SESSION['ourcss'] = str_replace('<' . 'style>','',str_replace('<' . '/style>','',urldecode($_GET['cssextra'])));
    echo $_SESSION['ourcss'];
    }
    } else if (strpos($_SERVER['QUERY_STRING'],'cssextra=')) {
    $sbits=explode("cssextra=", str_replace('#','&',$_SERVER['QUERY_STRING']) . '&');
    $ssbits=explode("&",$sbits[1]);
    if ($ssbits[0] != '' && strpos(urldecode($ssbits[0]), "{") === false) {
    $_SESSION['ourcss'] = str_replace('<' . 'style>','',str_replace('<' . '/style>','', ' body { font-family:' . str_replace('+',' ',urldecode($ssbits[0])) . '; }' ));
    echo $_SESSION['ourcss'];
    } else {
    $_SESSION['ourcss'] = str_replace('<' . 'style>','',str_replace('<' . '/style>','',urldecode($ssbits[0])));
    echo $_SESSION['ourcss'];
    }
    } else if (strpos($_SERVER['QUERY_STRING'],'ourcss=')) {
    $sbits=explode("ourcss=", str_replace('#','&',$_SERVER['QUERY_STRING']) . '&');
    $ssbits=explode("&",$sbits[1]);
    if ($ssbits[0] != '' && strpos(urldecode($ssbits[0]), "{") === false) {
    $_SESSION['ourcss'] = str_replace('<' . 'style>','',str_replace('<' . '/style>','', ' body { font-family:' . str_replace('+',' ',urldecode($ssbits[0])) . '; }' ));
    echo $_SESSION['ourcss'];
    } else {
    $_SESSION['ourcss'] = str_replace('<' . 'style>','',str_replace('<' . '/style>','',urldecode($ssbits[0])));
    echo $_SESSION['ourcss'];
    }
    }

… which you can access or try for yourself from this blog’s “All Posts” menu submenu option “Temporary User CSS” entering into the textarea the Google Font Family name of interest (all on its lonesome) before clicking the form submit button lower down to make it happen. We hope this is of interest, quorum!

WordPress Temporary User CSS Primer Tutorial

CSS is, perhaps, best learnt with a varied palette to work with, to see how an effect you want to create both …

  1. works itself, as the concept you want to see … and …
  2. interacts with a wide variety of other cascading styling settings, in terms of its robustness, and hierarchy of usefulness … in other words, your CSS positioning may be very important regarding its workings

Today we introduce some functionality that allows you to use this blog, with its default styling as your palette as an experimental tool, perhaps, for your CSS testing.

In these terms we try to have your own CSS be last in the order of CSS interpreted by the web browser, but it is really up to you to see for yourself what you need to do to make things happen.

This change involved … you probably guessed it … tweaking WordPress TwentyTen theme’s good ol’ header.php … in two parts …


<head>

// Lots of other Javascript and CSS work
// ...

<style>

// Lots of other CSS work
// ...


if (isset($_SESSION['ourcss'])) {
echo str_replace('<' . 'style>','',str_replace('<' . '/style>','',$_SESSION['ourcss']));
} else if (file_exists("localcss_" . my_t_d_server_remote_addr() . ".yzy")) {
$lcss = str_replace('<' . 'style>','',str_replace('<' . '/style>','',file_get_contents(("localcss_" . my_t_d_server_remote_addr() . ".yzy"))));
$_SESSION['ourcss'] = $lcss;
echo $lcss;
unlink("localcss_" . my_t_d_server_remote_addr() . ".yzy");
} else if (isset($_GET['cssask'])) {
} else if (isset($_GET['ourcss'])) {
$_SESSION['ourcss'] = str_replace('<' . 'style>','',str_replace('<' . '/style>','',urldecode($_GET['ourcss'])));
echo $_SESSION['ourcss'];
} else if (isset($_GET['cssextra'])) {
$_SESSION['ourcss'] = str_replace('<' . 'style>','',str_replace('<' . '/style>','',urldecode($_GET['cssextra'])));
echo $_SESSION['ourcss'];
} else if (strpos($_SERVER['QUERY_STRING'],'cssextra=')) {
$sbits=explode("cssextra=", str_replace('#','&',$_SERVER['QUERY_STRING']) . '&');
$ssbits=explode("&",$sbits[1]);
$_SESSION['ourcss'] = str_replace('<' . 'style>','',str_replace('<' . '/style>','',urldecode($ssbits[0])));
echo $_SESSION['ourcss'];
} else if (strpos($_SERVER['QUERY_STRING'],'ourcss=')) {
$sbits=explode("ourcss=", str_replace('#','&',$_SERVER['QUERY_STRING']) . '&');
$ssbits=explode("&",$sbits[1]);
$_SESSION['ourcss'] = str_replace('<' . 'style>','',str_replace('<' . '/style>','',urldecode($ssbits[0])));
echo $_SESSION['ourcss'];
}

</style>

… and …


function cookie_fonts() {

// Lots of other Javascript Cookie based work helping with control of some user styling settings discussed at ...
// https://www.rjmprogramming.com.au/ITblog/wordpress-user-body-background-primer-tutorial/
// ...


<?php
if (isset($_SESSION['ourcss'])) {
echo "\n" . ' appendtoa("cssextra", "" + encodeURIComponent("' . $_SESSION['ourcss'] . '")); ' . "\n";
}
?>

}
// ...
// and then lots more down to (unchanged) end of head section and document.body onload (where cookie_fonts() is the last onload functionality) as per ...
// ...
</script>
</head>
<body onload=" setTimeout(initpostedoncc, 3000); sdescih(); widgetcon(); precc(); courseCookies(); cookie_fonts(); " <?php body_class(); ?>>

So if you want to try your own CSS try this live run link, and see, below, some other suggestions (which simulate what the All Posts -> Temporary User CSS submenu does), that, if you click, and you want to reset use this reset link here.
