PHP/HTML/Javascript Sudoku Game Inline HTML Email Emoji Tutorial

PHP/HTML/Javascript Sudoku Game Inline HTML Email Emoji Tutorial

We wanted to add colour (via some linear and conic gradients) and emojis into the aesthetic mix, today, with our Sudoku game web application of yesterday’s PHP/HTML/Javascript Sudoku Game Inline HTML Email Tutorial.

Within web browser webpage there are no worries here, but as far as inline HTML email content goes …

• emojis work for some email clients such as the web browser or iOS mobile app version of Gmail, but not macOS Mail desktop application, for example … and …
• a lot of CSS3 does not translate into an email with inline HTML form and webpage content, and so gradients do not seem to be possible on the platforms we’ve encountered

Here’s some changed CSS styling …

<style>

.bright { border-right: 5px solid blue; }
.bbottom { border-bottom: 5px solid blue; }
td { font-size: 24px; width: 11%; height: 9%; text-align: center; vertical-align: middle; }
select { -webkit-appearance: none; font-size: 24px; padding: 1 1 1 1; border: 1px solid transparent; background-image: conic-gradient(pink, hotpink, lightpink); }
#smode { background-image: conic-gradient(yellow, lightyellow, orange); padding: 3 3 3 3; border-radius: 40px; }
th { text-align: left; vertical-align: top; }
textarea { width: 95%; background-image: linear-gradient(rgba(255,255,0,0.5) 18px, white 8%); }
input { width: 95%; }
button { -webkit-appearance: none; border-radius: 10px; }
body { background-image: linear-gradient(to bottom right, rgb(255,255,255), rgb(224, 255, 255),rgb(175, 238, 238), rgb(173, 216, 230),rgb(135, 206, 235),rgb(135, 206, 250),rgb(0, 191, 255),rgb(30, 144, 255),rgb(100, 149, 237),rgb(123, 104, 238),rgb(65, 105, 225),rgb(0, 0, 255),rgb(0, 0, 205),rgb(0, 0, 139),rgb(0, 0, 128),rgb(25, 25, 112)); }

</style>

PHP/HTML/Javascript Sudoku Game Inline HTML Email Tutorial

There are other forms of collaboration and sharing we can add to PHP/HTML/Javascript Sudoku Game Chat Names Tutorial‘s …

• email (via “a” “mailto” link) … and …
• SMS (via “a” “sms” link) … those being, as of today …
• popup window …
• new tab window
• inline HTML email (via PHP mail) form … gettable toable via 📧 (email &#128231; button calling on Ajax/FormData logic)

… that last option making capable for the user, the possibility of playing Sudoku within the email setting but call on the RJM Programming website to assess their “correct answering” status, completing the circle of communications, here …

… in the changed collaboration and sharing logic for index.php PHP Sudoku game that you should feel free to try and collaborate with below, as well, how we have decoupled the PHP from the (need for the) original HTML (to exist), meaning just having the one PHP code source will run your Sudoku game.

What’s new with inline HTML email form type of HTML with Gmail as the email client, for instance? We couldn’t see that any CSS styling is accepted, but you can use inline CSS styling within your HTML via the definition of style attribute values. And as you might have guessed from that, of course no Javascript is allowed to happen, and you should hide evidence, in your HTML, of intending to try to perform any Javascript.

PHP/HTML/Javascript Sudoku Game Chat Names Tutorial

Am sure there are a lot of users out there who’d prefer being referred to by their name rather than some form of number in their online activities. But we don’t want to be nosy and have an optional paradigm going with assigning names to our online Sudoku game players, else the default and fall through option is to refer to our players via a number basis, based on their IP address and web browser brand.

Involving names onto the chat typing “smarts” of yesterday’s PHP/HTML/Javascript Sudoku Game Chat Typing Tutorial, today, involves some PHP writing out some new Javascript arrays and functions …

Notice how, sometimes above (and elsewhere), looking at a scenario from within the iframe “child”‘s point of view, we can call “parent” Javascript, for example …

//$aswell.=’ parent.document.getElementById(‘ . “‘sudokui'” . ‘).placeholder=parent.document.getElementById(‘ . “‘sudokui'” . ‘).placeholder.replace(‘ . “‘(others typing)’,'(bit before a colon is your name)'” . ‘); ‘;
$aswell.=’ parent.document.getElementById(‘ . “‘sudokui'” . ‘).placeholder=parent.document.getElementById(‘ . “‘sudokui'” . ‘).placeholder.replace(‘ . “/\([^\)]*\)/g,'(bit before a colon is ‘ + ((parent.pargyn().length > 0) ? parent.pargyn() + ‘)’ : ‘your name)’)” . ‘); ‘;

… and …

if ((” . sizeof($relr)) != (” . $vsarrs)) {
$vsarrs=” . sizeof($relr);
$doaloop=false;
for ($iwr=1; $iwr<sizeof($relr); $iwr++) {
$lfld=str_replace(‘+’,’ ‘,urldecode(explode(“\n”, $relr[$iwr])[0]));
if (strpos($lfld, ‘:’) !== false) {
$renamebits.=” parent.mapfromto(‘” . explode(‘;’,$relr[-1 + $iwr])[-1 + sizeof(explode(‘;’,$relr[-1 + $iwr]))] . “‘,'” . explode(‘:’, $lfld)[0] . “‘); “;
}
}
if ($renamebits != ”) { $renamebit.=’ parent.domaps(); ‘; }
echo ‘<html><body onload=” parent.document.getElementById(‘ . “‘vsarrs'” . ‘).value=’ . “‘” . $vsarrs . “‘” . ‘; ‘ . $renamebits . ‘ “></body></html>’;
} else {

Also notice with the changed collaboration and sharing logic for index.php PHP Sudoku game that you should feel free to try and collaborate with below, as well, how we have decoupled the PHP from the (need for the) original HTML (to exist), meaning just having the one PHP code source will run your Sudoku game.

PHP/HTML/Javascript Sudoku Game Chat Typing Tutorial

We’ve seen chat websites and SMS messaging types of apps that indicate to users in communication with each other when another user is typing, so that they have a chance to wait for that correspondence before sending their own next piece of correspondence. And so, onto yesterday’s PHP/HTML/Javascript Sudoku Game Collaboration Notifications Tutorial‘s chat functionality we wanted to try to code for this functionality.

What events on the chat textbox can help?

• onkeydown event can be used to indicate chat typing ahead of …
• onblur event can be used to determine when typing ends and sending of correspondence begins

Today we’ve got an inhouse version of a well known mathematical (but you don’t have to be a mathematician to play) game called Sudoku which you regularly find in the puzzles section of the newspaper, like the KenKen game of HTML/Javascript KenKen Game Primer Tutorial times.

The rules are, for our version …

• there are 81 squares in a 9×9 grid that need to get assigned a counting number from 1 to 9, but some are filled out already to help you
• no row of nine should contain a duplicate counting number
• no column of nine should contain a duplicate counting number
• none of the 9 3×3 squares within that 9×9 grid should contain a duplicate counting number

Simple, when put like that, but can be quite challenging in the solving!

Feel free to try our first draft sudoku.html Suduko game you can try in a new window, or below …

HTML/Javascript KenKen Game Primer Tutorial

KenKen is a well known mathematical game, featuring in the puzzle section of some newspapers. We see it here in Sydney, Australia, in The Sydney Morning Herald newspaper.

Do not know what the paper KenKen puzzle creators use to create their KenKen puzzles, but we do end up with a bit of a trial and error approach (populating the KenKen grid with numbers).

Am sure if you are interested in the methodology you would not have too much trouble seeing what we did by examining the HTML and Javascript code you could call kenken.html

KenKen consists of a grid (ours is 6×6) of numbers (from 1 to 6) not repeated horizontally nor vertically within that grid.

The user solving the KenKen puzzle is not shown those numbers, except the ones caught in a 1×1 “cage” … and these can help you greatly to solve the puzzle, the rest of which is made up of 1×2 and 1×3 “cages” that have a “clue” … for example …

• 12*123456

• 7+123456

• 3-123456

• 2/123456

… which tell you a clue about the numbers you can use dropdowns with which to solve.

There is no surprise with the HTML “grid” being composed of an HTML table element, shadowed by a multi-dimensional array we initialize for our 6×6 grid scenario via …


var mda=[[0,0],[0,0],[0,0],[0,0],[0,0],[0,0],[0,0],[0,0],[0,0],[0,0],[0,0],[0,0],[0,0],[0,0],[0,0],[0,0],[0,0],[0,0]];


in the Javascript.

You’ll see that we made use of the HTML sup tag for a superimposed feel to the clues within some of the grid squares at the start of the “cage”.

Hope you get some HTML and Javascript ideas about games, and have fun playing this mathematical and logic game, today, with our live run.
