WordPress Blog Comments URL Right Click Popup Check Prevent Default Tutorial

We’re coming back to the previous WordPress administrator Comment moderation section URL Popup Window Checker functionality last talked about with WordPress Blog Comments URL Right Click Popup Check Tutorial.

We were finding before this Javascript code fix …

<?php

setTimeout(function(){
if (document.body.innerHTML.indexOf('Comments</h1>') != -1) {
var als=document.getElementsByTagName('a');
for (var ials=0; ials<als.length; ials++) {
if (('' + als[ials].href).indexOf('http') == 0 && ('' + als[ials].href).replace('wordpress.org','rjmprogramming.com.au').indexOf('rjmprogramming.com.au') == -1) {
als[ials].oncontextmenu=function(evt){ evt.stopPropagation(); evt.preventDefault(); if (woowoo) { if (!woowoo.closed) { !woowoo.close(); woowoo=null; } } woowoo=window.open(evt.target.href, '_blank', 'left=' + eval(-480 + eval('' + screen.width)) + ',top=0,width=500,height=200'); setTimeout(function(){ woowoo.focus(); }, 500); };
als[ials].ontouchend=function(evt){ evt.stopPropagation(); evt.preventDefault(); if (woowoo) { if (!woowoo.closed) { !woowoo.close(); woowoo=null; } } woowoo=window.open(evt.target.href, '_blank', 'left=' + eval(-480 + eval('' + screen.width)) + ',top=0,width=500,height=200'); setTimeout(function(){ woowoo.focus(); }, 500); };
}
}
}
}, 6000);

… in admin-header.php that popup windows were being created but immediately falling behind the main WordPress blog “admin” section Comments section webpage window, annoyingly. Our investigations tracked it down to the right click “default behaviour” forcing the popup window out of view.

Aaaahhhh

… thank you, Sage … preventing that right click menu from appearing, and so not compromising window focus web browser rendering. We do very little WordPress administration on mobile, but just in case, we added an ontouchend event (usually happening at the finish of a gesture) mimicking of the non-mobile right click logic, for good measure.

WordPress Blog Comments URL Right Click Popup Check Tutorial

In the past we have only mildly changed the administration section of our TwentyTen themed WordPress_.org blog (you are currently reading) here at RJM Programming, and some of that involved new WordPress plugins, as you can read a bit about with WordPress Blog Data URI in Post Plugin Tutorial.

We maintain that blog within an “admin” part of the WordPress blog, and any changes we’d put in a “dessert island wish list” usually just absorb and move on, but we thought we’d improve on …


WordPress comment moderation


… by allowing myself (well, thanks awfully, I don’t really know what to say) the chance to …

• on any comments webpage …
• right click on “a” links whose domain is neither wordpress.org nor rjmprogramming.com.au and … in so doing …
• be able to see a small popup window to the top right of the screen

… because, even if we wanted to argue with the great Akismet _{(we use and are very happy with around here)} calling it spam, one of the steps we’d want to investigate would be to rule out a potential “broken link”, and this is a way to check for that.

Now, what we discovered marrying “a wish” with “an action plan” was that …

• in parallel to the TwentyTen non-admin parts being manageable largely via changes to good ol’ header.php … we found …
• the easy approach to changes in the admin parts could be achieved by changes to good new admin-header.php

… with our action plan moving to “deployment” via PHP (writes Javascript) admin-header.php modified code …

<?php

<script type="text/javascript">
document.body.className = document.body.className.replace('no-js','js');

setTimeout(function(){
if (document.body.innerHTML.indexOf('Comments</h1>') != -1) {
var als=document.getElementsByTagName('a');
for (var ials=0; ials<als.length; ials++) {
if (('' + als[ials].href).indexOf('http') == 0 && ('' + als[ials].href).replace('wordpress.org','rjmprogramming.com.au').indexOf('rjmprogramming.com.au') == -1) {
als[ials].oncontextmenu=function(evt){ window.open(evt.target.href, '_blank', 'left=' + eval(-500 + eval('' + screen.width)) + ',top=0,width=500,height=200'); };
}
}
}
}, 6000);
</script>

?>

Pretty straightforward really, and perhaps of interest to some WordPress_.org comment moderators out there!

WordPress Blog Data URI in Post Plugin Tutorial

Today, we’ve got another WordPress plugin to suit the TwentyTen themed blog you are reading, adding onto those described at WordPress Blog Collaborative Annotated Email FormData Post Tutorial.

This plugin suits the Content Editor creating the posts in the administration end of the WordPress TwentyTen themed blog, when they desire to add a data URI, rather than an absolute URL or relative URL (which would probably involve an upload). To use data URIs will make your blog posts independent of web server file arrangements, but if you are looking for this to save (web server) diskspace, this might be a mute point. The diskspace could still be used up by the MySql database storing the data URI in its base64 encoding.

What does our PHP plugin call on to do its thangthing?

• plugin actions (similar to other plugins talked about in postings below) …
  1. add_action( ‘admin_notices’, ‘rjmprogramming_Data_URI_Helper’ ); // for Javascript adding HTML to webpage dynamically
  2. add_action( ‘admin_footer’, ‘rjmprogramming_data_uri_helper_css’ ); // for CSS
• File API and its FileReader.readAsDataURL() method to browse for local device files
• highlighted text (within the blog posting, where we rely on TwentyTen “id”s and “className”s to identify user intent) that gets substituted by the data URI if successful … when the user clicks/touches the newly introduced …
• “Data URI Highlighted Text Replacer” a link

And so we have for you today rjmprogramming-data-uri-helper.php PHP source code that goes into this plugin should you want to write your own version for a theme that isn’t the WordPress TwentyTen theme (looking for those TwentyTen “id”s and “className”s as changepoints), and/or view us using it with today’s animated GIF presentation.

WordPress Blog Collaborative Annotated Email FormData Post Tutorial

Yesterday’s WordPress Blog Collaborative Annotated Email User Experience Tutorial helped with practicalities regarding user experience with this WordPress Blog highlighting of text accumulated into the body (as HTML attachment) and subject (as text) of an Annotated Email form of collaborative communication.

The “subject” extension here makes it all the more important to try to look out for long email URLs that will exceed the web server limit here. When too long, that …

• previous GET method of navigation … needs to be converted to a …
• POST method of navigation

… and today we do not write out any discrete HTML form element to do this (when required), but instead resort to the wonderfully powerful combination of …

• Ajax XMLHttpRequest object … as the conduit for …
• FormData object

… to be used by the new dynamic thinking Javascript function as below …


function iftoolongpost(prefixu, restsub, restu) {
var prefixrest=prefixu.replace('&body=', encodeURIComponent(restsub) + '&body=') + restu;
if ((prefixrest).length > 900) {
// dynamic form
var xhr = new XMLHttpRequest();
var form=new FormData();
form.append('to', decodeURIComponent(prefixrest.split('to=')[1].split('&')[0]));
form.append('subject', decodeURIComponent(prefixrest.split('subject=')[1].split('&')[0]));
form.append('body', decodeURIComponent(prefixrest.split('body=')[1].split('&')[0]));
xhr.open('post', '//www.rjmprogramming.com.au/HTMLCSS/emailhtml.php', true);
xhr.send(form);
// end of dynamic form
location.href='#hfloater';
} else {
document.getElementById('aeciframe').src=prefixrest;
}
}


… called in that different calling arrangement as per …


document.getElementById('hfloater').innerHTML+='<b>Annotated Email <a class="hlclass" style="inline-block;cursor:pointer;text-decoration:none;" onclick="iftoolongpost(this.title, encodeURIComponent((this.innerText || this.contentWindow || this.contentDocument)), encodeURIComponent(this.innerHTML.substring(this.innerHTML.indexOf(String.fromCharCode(60)))));" data-href="//www.rjmprogramming.com.au/HTMLCSS/emailhtml.php?to=&subject=Re%3a%20' + encodeURIComponent(document.title.split('|')[0]) + '%20%28' + encodeURIComponent(document.URL) + '%29%0a&body=" title="//www.rjmprogramming.com.au/HTMLCSS/emailhtml.php?to=&subject=Re%3a%20' + encodeURIComponent(document.title.split('|')[0]) + '%20%28%20' + encodeURIComponent(document.URL) + '%20%29%0a&body=" target=aeciframe onmouseover="this.title=emaileeis(this.title);" ontouchstart="this.title=emaileeis(this.title);" id=b_hfloater_annotated_email>' + aec + '</a></b><iframe id=aeciframe name=aeciframe style=display:none; src=#></iframe><br>';

WordPress Blog Collaborative Annotated Email User Experience Tutorial

Did you try yesterday’s WordPress Blog Collaborative Annotated Email Tutorial highlighting of text Annotated Email functionality? If you did, you might have found a “hair trigger” timed user experience. You had a very small amount of time to decide on any amendments “by hand” to your email.

On this, did you notice how we relied on a Javascript prompt window to garner an email address off the user? There is method in this “kludginess”. We wanted the highlighting not to be destroyed by a change of focus. The downside though, is that the whole time you spend answering contributes to any setTimeout based timing we have going before we automatically make the highlighting functionality menu disappear. Today, we control that, waiting an extra 10 seconds or so after that for the user to start entering their own Annotated Email content, should they wish, and the HTML div contenteditable=true is reminded by a new onchange replenishment of the delay that the user is still writing … a bit like with SMSes and those blinking dots telling you the other SMSer is writing something (but not as cute here, looks wise, alas).

Again, into the WordPress (changed PHP rjmprogramming-multi-lookup.php) plugin or header.php the changed (header.php) code involves new Javascript (that dynamically creates HTML) as per …

Some email clients baulk at downloading HTML attachments, so the other change today is to append the wording of the email’s inherent HTML to the email subject, so if an emailee is unlucky in this way, they can still get “second prize” … but no cigar!

WordPress Blog Collaborative Annotated Email Tutorial

Further to WordPress Plugin Primer Tutorial of recent times, we’re adding to that “highlighting of blog text” (dynamic menu) the options …

• Email (that highlighted text) via the email client application via a “mailto:” “a” link
• SMS (that highlighted text) via the email client application via a “sms:” “a” link
• Annotated Email of the highlighted text converted to mark (marked up) text, accumulated onto for the whole WordPress blog session,and emailed off via PHP’s mail function, as an HTML email attachment (downloaded at the emailee end)

… and we think the last of these has good scope for collaborative thoughts and usages. Want to try it out? You’re here, ready. Just highlight some text to get started.

Into the WordPress (changed PHP rjmprogramming-multi-lookup.php) plugin or header.php the changed (header.php) code involves new Javascript (that dynamically creates HTML) as per …

WordPress Plugin Primer Tutorial

Normally we make changes to this TwentyTen themed WordPress blog by changing that theme’s wp-content/themes/twentyten/header.php file. But today we show you how to write the PHP code needed to write a WordPress.org admin login plugin to create a hyperlink to a Wikipedia page regarding any text you have highlighted on your WordPress admin area webpage.

We thank …

• WordPress Codex
• WordPress Codex “Writing a Plugin”
• WordPress Codex “Plugin API”
• Hello Dolly plugin

… and we think you should read …

• Hooks
• Actions
• Filters
• Pluggable Functions
• Plugins directory

For us, with our very simple rjmprogramming-wikipedia-lookup.php plugin, we only needed the one piece of PHP to sit in the current WordPress wp-content/plugins directory, and then immediately be accessible to the WordPress blog admin area’s Plugins -> Activate option …


<?php
/**
* @package Rjmprogramming_Wikipedia_Lookup
* @version 1.6
*/
/*
Plugin Name: Rjmprogramming Wikipedia Lookup
Description: Float a Wikipedia lookup link for highlighted text of an admin webpage.
Author: Robert James Metcalfe
Version: 1.6
Author URI: http://www.rjmprogramming.com.au/
*/

// This creates the Wikipedia lookup hyperlink
function rjmprogramming_wikipedia_lookup() {
$wikipedia_page = "Wikipedia Main Page";
echo '<a target="_blank" title="Wikipedia lookup of ..." onmouseover="var xsel=' .
"''" . '; xsel=window.getSelection().toString(); if (xsel.length == 0) {' .
' xsel=document.selection.createRange().htmlText;' .
' } if (xsel.length != 0) { this.innerHTML=xsel; this.href=' . "'" . '//wikipedia.org/wiki/' .
"'" . ' + xsel.replace(/\ /g,' . "'" . '_' . "'" . '); } " ontouchstart="var xsel=' .
'; xsel=window.getSelection().toString(); if (xsel.length == 0) {' .
' xsel=document.selection.createRange().htmlText; }' .
' if (xsel.length != 0) { this.innerHTML=xsel; this.href=' . "'" . '//wikipedia.org/wiki/' . "'" .
' + xsel.replace(/\ /g,' . "'" . '_' . "'" . '); } " id="rjmprogramming_wikipedia_lookup"' .
' href="//wikipedia.org/wiki/Main_Page">' . $wikipedia_page . '</a>';
}

// Now we set that function up to execute when the admin_notices action is called
add_action( 'admin_notices', 'rjmprogramming_wikipedia_lookup' );

// We need some CSS to position the hyperlink
function rjmprogramming_wikipedia_css() {
// This makes sure that the positioning is also good for right-to-left languages
$x = is_rtl() ? 'left' : 'right';

echo "
<style type='text/css'>
#rjmprogramming_wikipedia_lookup {
float: $x;
padding-$x: 15px;
padding-top: 5px;
margin: 0;
font-size: 11px;
}
</style>
