Event Calendar PHP Bookmark Tutorial

Client meets server today, allowing the PHP data storage talents in yesterday’s Event Calendar PHP Tutorial‘s work to meet a “clientside” way to …


Record to Remember via Bookmark


… use the web browser Bookmarks to help you recall an Events in Month report with long entries.

Involving a Bookmark still needs those “get” ? and & arguments, and we allow the PHP to lookup for us the data underscoring an address bar URL such as …

… that mapping being possible, now, making use of a pseudo hashtag arrangement … your Clayton‘s hashtag, if you will!

To start to use a hashtag suits, as your hashtag navigation only makes sense in the “clientside” woooorrrrrllllddd, and even there, really using one only tries to position a webpage where an element with an ID matching the hashtag sits (and we are never going to have this ID element in our work), and in the meantime we’ve passed across from the child PHP to the parent HTML a valuable piece of information helping the link to the Bookmark system be possible. The Javascript codeline (you may have noticed) …


var documentURL=document.URL;


… as stupid and simple looking as it is, is crucial for us. We get child webpage parts (like our PHP) to change document.URL to a far too long in normal circumstances address bar URL the rest of the code feeds off. It’s just that now, that far too long in normal circumstances address bar URL has a #[hashtag] appended such as …


#August__2023_00000__1


… uniquifying a Month, Year Events in Month identifier part with a version of the user’s IP address (so that they only see what is relevant to them).

Address bar URLs such as “https://www.rjmprogramming.com.au/HTMLCSS/events_in_month.php?exactlabel=August__2023_00000__1” are Bookmark_able, and so we allow for similar outcomes with less concern about how much data is being “recorded” and recallable (via that web browser’s Bookmark system).

Also, today, a lot of CSS tweaks, so that the CSS styling now looks like …

Event Calendar PHP Tutorial

Let’s face it. Serverside PHP is just great! It opens up so many opportunities regarding data in your web applications.

As such, onto yesterday’s Event Calendar New Window Tutorial logic we now have a …


Record to Remember


… form submit button (toggling) value to start involving PHP with those longer datasets of Event in Month descriptions, in our most recent project. What do we use as the data conduit? No, not a database. No, not a serverside flat file. No, not clientside window.localStorage nor window.sessionStorage nor HTTP Cookies. We store long Event in Month description data in our new events_in_month.php PHP itself. And this same PHP can populate options in a new dropdown element in the parent to facilitate the recalling of any relevant “Record to Remember” recordings.

The PHP is kind of short, so we will show it below, including one MAMP example of that “self storage” …

Event Calendar New Window Tutorial

Onto yesterday’s Event Calendar Remembered Tutorial‘s “Mystery Dilemma” …

But, there’s an inherent weakness with the design, we’ll go into more into the future.

… well … it’s a perennial for us, regarding how if you stick with clientside thinking, only, web applications, when the amount of data to remember starts adding up, the “get arguments approach” ( ie. use ? and & arguments at the address bar ) is restricted by length restrictions regarding URL lengths.

Rather than jump to PHP serverside ideas just yet, we wanted to show some more ideas, staying with “clientside only thinking”, today, as well as improving the UX (user experience) and small steps forward regarding styling.

Okay then, regarding the idea to remember an Event in Month form, when there is a lot of data, and staying “just clientside”, we’ve coded for a “New Window” idea, albeit not as memorable as the default “Remember in Bookmark” possible for your smaller datasets. However, in saying that, we found that within this new window, with our Google Chrome web browser, we could …

1. bring up Context Menu with a right click or two finger gesture within the popup window webpage content …
2. pick Inspect option …
3. be in Elements tab of your Web Inspector … and …
4. highlight top <html> tag …
5. Context Menu with a right click or two finger gesture …
6. pick Copy -> Copy outerHTML … so that …
7. your Event Calendar for your Events in Month choice is in a text buffer … ready for you to …
8. Paste into a Text Editor that Events in Month webpage to store (perhaps in a MAMP local Apache/PHP/mySql web server environment, where you can further look at and develop your own ideas)

The user is told when the switch to “New Window” compromise becomes active, decided upon by reconstructing the proposed address bar URL regularly and when too long …


function formanalyze() {
var fio=document.getElementsByTagName('form')[0];
var delm='?';
var fioih=fio.innerHTML;
var fions=fioih.split(' name="');
var testurl=documentURL.split('?')[0].split('#')[0];
for (var ijk=1; ijk<fions.length; ijk++) {
testurl+=delm + fions[ijk].split('"')[0] + '=' + encodeURIComponent(document.getElementById(fions[ijk].split('"')[0]).value);
delm='&';
}
setTimeout(formanalyze, 3000);
if (eval('' + testurl.length) >= 750) {
if (document.getElementById('remember')) { document.getElementById('remember').value='New window'; }
if (document.getElementById('rememberme')) { document.getElementById('rememberme').value='New window'; }
if (document.getElementById('remembermoi')) { document.getElementById('remembermoi').value='New window'; }
} else {
if (document.getElementById('remember')) { document.getElementById('remember').value=document.getElementById('remember').value.replace(/^Remember$/g, 'Remember via Bookmark'); }
if (document.getElementById('rememberme')) { document.getElementById('rememberme').value=document.getElementById('rememberme').value.replace(/^Remember$/g, 'Remember via Bookmark'); }
if (document.getElementById('remembermoi')) { document.getElementById('remembermoi').value=document.getElementById('remembermoi').value.replace(/^Remember$/g, 'Remember via Bookmark'); }
}
return eval('' + testurl.length);
}


… the form submit buttons are reworded accordingly.

Another idea from this blog thread’s inspiration …

… we’ve now addressed in today’s “second draft” is allowing for an optional bold Event Day Blurb Title, available to the user via a new dropdown “Bold Title” option.

And, how can we do more with colour, to help the right bits stand out, and be consistent? We thought …

• text shadow means by which the text of Event Calendar can be more impactive …
  
<div style="text-shadow:-1px 1px 1px #ff2d95;" id=eventcalendar></div>

• dropdown element conditional styling …
  
<style>
.dayb {
color: white;
background-color: red;
padding: 5 5 5 5;
}


.dow {
color: purple;
font-style: bold;
}

.selday {
margin-left: 8px;
background-color: rgba(255,0,0,0.7);
display: inline-block;
width: 50px;
}
</style>

  …
  
if (thislabel.substring(0,1) == 'i') {
if (thisval.trim() != '') {
document.getElementById(thislabel.replace('i', 'sel')).style.color='white';
document.getElementById(thislabel.replace('i', 'sel')).style.backgroundColor='red';
}
document.getElementById(thislabel.replace('i', 'opt')).innerText=thisval.replace(/\+/g, ' ').replace(/\ \ \ /g, ' + '); //.replace(/\+$/g, ' ');
document.getElementById(thislabel).value=thisval.replace(/\+$/g, ' ');
} else {
document.getElementById(thislabel).value=thisval.replace(/\+/g, ' ').replace(/\ \ \ /g, ' + ');
}
}

• placeholder on Blurb conditional existence …

Event Calendar Remembered Tutorial

We were inspired by an Event Calendar pamplette we saw the other day …

… to write a new “proof of concept” Events in Month web application, whose content can be recalled via the web browser’s Bookmark methodologies.

We liked the ideas for day of week and/or date of month grouping arrangements we included, being, the way we interpreted it …

• just on this day in this month … default
• on this day of the week throughout the month in question … “…“
• on this day and some others in that month in question … “&” … to start with and further amendments available via contenteditable=true span element
• “Clone” value allows for multiple separated “blurbs” for the one signature day
