Previous WordPress User Font Families Primer Tutorial as shown below, yesterday …

In the world of client/server programming it is surprising that PHP (on the server side) and Javascript (on the client side) can so often both be approaches to solving a problem. But maybe it shouldn’t be so surprising, since they both share the mutual “HTML” friend in the middle.

Our WordPress changes today reflect that client/server teamwork, with the access both PHP and Javascript have to cookies coming in handy at different stages of our CSS styling modifications to our WordPress blog (here). The modifications centre around offering the user the ability to choose their own font families to use when viewing this blog. Should the user go down that route of specifying their own font families for any/all of …

  • blog title
  • post title
  • post contents (or “innards”)

… this change is stored in cookies and will remain in place (for 6 months that is) as the default font setting for that web browser accessing this WordPress blog from then on, until the user picks another font family or leaves the blog to pick its own default font family.

And what is the mechanism for the user to control that? Web browser URLs will do it, or some All Post menu submenus we’ve written for the purpose.

So what are the two ways for the client/server Javascript/PHP cookie access to work?

… well, this was good in theory, but its “backdoor” approach to WordPress development (to see some good information here please read this) didn’t take into account the way WordPress manipulates client cookies, and controls them in scenarios where users are logged in, which we don’t want to demand here … so … lowering expectations a bit … what we have is functionality that can allow for user defined CSS styling within a web browser session, but not between sessions. The way we end up “not using cookies” so much anymore, is to fix the HTML a links on the page (via function appendtoa(thisiid, thisv) of code below) to have, via PHP $_GET[] parameters, for the functionality to flow through for as long as the user is in a session using the blog, and defining their own CSS “looks” via the “All Posts” submenu options.

And so, below, we add in new functionality for the user to control the blog’s Header Section’s Border look, and you’ll see these two approaches in action in two separate sections of the WordPress Blog’s PHP header.php (usual file to make changes to) as below (where we moved the timing of this functionality to being the last thing done at the document.body onload event

  • PHP can access $_SERVER variable $_SERVER[‘HTTP_COOKIE’] and PHP is really useful here to change the CSS styling in the web page header as the server mechanism getting in ahead of the Javascript client (though this Javascript may have been able to work it manipulating DOM document.head … but this is not our preferred method if PHP is there, and because it is a WordPress blog, PHP is there (so use it) … alas, the PHP $_SERVER[‘HTTP_COOKIE’] (as might be expected) is not useful for client cookie detection, so added function lookAtCookies() to Javascript above as an alternative client method not using document.header but, rather, appending into document.body <style> blah blah blah </style> information to get the job done) (bold changes below)

Again the mechanism for the user to control this themselves is 4 submenus off the All Posts menu. Blog New Pages like below (for example of 3 “Pick Your Own Blog Header Section Border”) will do it (and show the idea) …


<p id='rjmwp_masthead_border'>Please feel free to enter a Border (CSS Styling (eg. 2px solid green)) to use for the Blog Header Section (nothing uses default and you get a preview as you tab out of the text box): <br><input id='rjmwp_masthead-border' type='text' value='' onblur=' change_ff(this, this.value); ' title='//www.rjmprogramming.com.au/ITblog/?rjmwp_masthead-border=' onfocus=" this.value=cookieAVal('rjmwp_masthead-border');"></input> <input type='button' onclick=" location.href=document.getElementById('rjmwp_masthead-border').title; " value='Show Blog This Way with this Web Browser Session Until a Revisit Here'></input></p>

You can try it yourself by accessing the All Posts menu to see for yourself. Again, we hope some ideas spring from all this for you, and remember that HTML inspector tools like Firefox’s Firebug are invaluable for helping with the examination of that “middle” HTML to tweak on what might be right and what might be wrong with your programming.

  • PHP can access $_SERVER variable $_SERVER[‘HTTP_COOKIE’] and PHP is really useful here to change the CSS styling in the web page header as the server mechanism getting in ahead of the Javascript client (though this Javascript may have been able to work it manipulating DOM document.head … but this is not our preferred method if PHP is there, and because it is a WordPress blog, PHP is there (so use it) … alas, the PHP $_SERVER[‘HTTP_COOKIE’] (as might be expected) is not useful for client cookie detection, so added function lookAtCookies() to Javascript above as an alternative client method not using document.header but, rather, appending into document.body <style> blah blah blah </style> information to get the job done) (bold changes below)

And so we come to the mechanism for the user to control this themselves, as 3 submenus off the All Posts menu. Blog New Pages like below (for example of 3 “Pick Your Own Post Contents Font”) will do it (and show the idea) …


<p id='rjmwp_base_font_family'>Please feel free to enter a Font Family to use for the Post Contents (nothing uses default and you get a preview as you tab out of the text box): <br><input id='rjmwp_base_font-family' type='text' value='' onblur=' change_ff(this, this.value); ' title='//www.rjmprogramming.com.au/ITblog/?rjmwp_base_font-family=' onfocus=" this.value=cookieAVal('rjmwp_base_font-family');"></input> <input type='button' onclick=" location.href=document.getElementById('rjmwp_base_font-family').title; " value='Show Blog This Way with this Web Browser Until a Revisit Here'></input></p>

You can try it yourself by accessing the All Posts menu you see above. We hope some ideas spring from all this for you, and remember that HTML inspector tools like Firefox’s Firebug are invaluable for helping with the examination of that “middle” HTML to tweak on what might be right and what might be wrong with your programming.

One Response to WordPress User Header Section Border Primer Tutorial

  1. Take photos says:

    My partner is trying to keep me off the online world as she believes I devote far too much
    time on it. Even so, I do take pleasure in stuffing my brain with as much
    knowledge as I get my hands on. I also always like to spend some time to thank people when they have taken the time to
    help me, and that’s why I’m commenting now.
    Thank you for this useful content.
