I am trying to add a Google calendar to a website I'm making that the client will be able to update themselves. I found this: http://mikeclaffey.com/google-calendar-into-html/ which has been quite helpful, but I am a bit stuck.
The website I am building is using PHP template and the page contents is contained within the $content variable. Here is the link I'm working on: http://victoriasawyer.com/AmosTheTransparent.
The calendar feed is the top one of the two lists of Tour Dates. I would like the top one to look similar to the bottom one. The same would be ideal but not necessary.
The biggest issue I'm having is with the start date and time. In the title of the event I would like just the date to show (preferably like 10/03/14) not the time. I have figured out how to display just the time separately without issue. Is there some way to change the date format?
The other issue I'm having is the order that the events are appearing. I would like the events to show with the soonest one first in the list and the furthest one last in the list. I added the additional parameters as instructed in the tutorial (orderby=starttime and sortorder=ascending) but they do not display correctly.
The url I am using is: https://www.google.com/calendar/feeds/qmfadhgtq2kmabsi3dlb456v98%40group.calendar.google.com/public/full?orderby=starttime&sortorder=ascending&futureevents=true&alt=json. Is there something I can adjust or add to fix the order?
Any help will be much appreciated (even if you can recommend an alternative. It just needs to be customizable, and so far this seems to be the best option I have found).
You can use PHP's DateTime class like this:
$date = new DateTime('Sun Nov 16 2014 00:30:00 GMT+0000');
echo $date->format('Y-m-d');
You can then use the predefined formats in PHP which are listed here to format it into whatever style you like.
echo $date->format('d/m');
echo $date->format('d/m/Y');

I'm fairly new to PHP, and I'm trying to write a script that solves the following
I have an RSS feed that gets saved to my server every 10 minutes (copied from elsewhere).
There is a problem with the timestamps (pubDate tag) on the RSS feed, they always have the correct date but 00:00:00 GMT as the timestamp (I have no control over this).
Therefor, when I use an autotweeting program to tweet updates from the feed (it checks it every hour or so), it won't - It only tweets the first update of each day as a result.
Therefor, what I'm trying to do to fix it to some degree is to check if the feed has changed, and if it has, change the saved pubDate to the current server time on only the new items.
I'm also kind of confused as to how I can have it check for changes - If I have a corrected version (with fairly accurate timestamps) saved to my server, it will ALWAYS think there are changes, because the timestamps will always be 00:00:00. I'm thinking, check both feeds for items including the full strings such as <guid isPermaLink="true">http://services.runescape.com/m=adventurers-log/a=161/display_player_profile.ws?searchName=A13d&id=-463827091</guid> - Since the id= at the end stays constant, it would only change the <pubDate> of items found to be new.
http://services.runescape.com/m=adventurers-log/a=161/rssfeed?searchName=A13d Here is a feed as an example. If anyone could get me started or point me to some kind of tutorial that might help, I'd really appreciate it. This is over my head, but something I need to learn how to do.
Maybe there is something wrong with your code parsing the timestamp, date format perhaps?
I believe the method of doing full string comparisons(<title> & <description>) between items with the same <guid> is your best bet. Here is some reading about RSS duplicate detection if you are interested.
For a school project we have to build a web app. I'll be creating something where people can keep track of their classes, their homework, and their free time. A planner/calendar. (I'm making it sound really lame here but hey, I'm tired and English isn't my first language ;) )
I'll be working in CodeIgniter for the PHP logic, combined with the usual.. CSS, jQuery, mySQL. PHP is a requirement for the course; I chose to do this in CI because well.. I wanted to learn the framework. We kind of have to show off what we can do at this point of our 'school career'.
Anyway, I would like to ask for some insights regarding a feature I want to implement. At the top of my page, I would like to show a bar which contains the days of the month. Below the day number, I would be showing how many tasks are added on that day by means of some dots. When the user clicks previous or next, I want to show the previous/next month's days. I also want some sort of slider underneath this box which the user can use to slide left and right, and cycle through the days that way. I hope that made sense?
EDIT 2: I want the slider to be dynamic. If the user slides to the previous or next months, or clicks the buttons, I want it to load the days of the previous/next months and show those. Also, say we're at the 26th of a month, the slider would have to show something like 10-31 of this month AND 1-10 of the next month. I suppose I'll also have to change my month indication (not like in the image here) so a user knows when another month starts (I'll show them the name of the month).
Here's a picture (don't mind the day numbers being messed up, I was lazy doing that correctly in Photoshop. will fix that tomo):
I've been looking at the jQuery UI sliders. I suppose I'd have to grab the number of days from a database or by using PHP? I guess the cal_days_in_month function could come in handy here. When the user clicks on the arrows or slides left or right, I don't want the page to refresh. Should I go with ajax calls there? I'm not quite sure how to implement this, to be honest. The numbers are also links to a calendar type of view which shows underneath this bar.
Could I possibly use the CI Calendar class for this? Or is it more for full-fledged google calendar-type of calendars? I thought this screencast could perhaps be useful?
If possible, could someone please provide some insights on how to start working on this and which plugins/etc I could perhaps use? I'm not sure where to start, to be honest. I'm sure I can work this out somehow, but I guess it'd be nice to get a kickstart by means of some help here. The main problem I'm seeing is the slider/next/previous thing and loading in the previous/next month's days.
Thanks in advance.
EDIT: I realise some people might say/think 'OMG, why don't you just use the skills you have instead of trying something you have to ask us about!'. Well, this is because I actually want to learn something while doing this project. Keep in mind, I'm not asking for lines of code here, I'm just asking for some insight on where to start and what stuff to use; perhaps little snippets that can help me out. Thanks.
UPDATE:
I got a very basic 'day bar' working. Still without a slider, nor do the previous and next buttons work, but hey.. at least it fills it in dynamically. It shows the 5 days previous to the current day, then this month till the end. Whatever is left to fill in gets filled with days of the next month. Quite basic. However, I do have a couple of questions!
Since someone told me yesterday that I was breaking design patterns by doing some stuff the way I was doing it, I'm extremely paranoid about the way I'm working now and I would really like some feedback from 'CodeIgniter pro's'. To fill in the 'day bar', I created a helper with a couple of methods. (One method to dynamically fill that 'month year' thing you see in the picture, another method init() which loads the list of the days, like I explained before). I loaded this helper in the controller and I'm now using the methods in my view:
<ul>
<?php
init($current_day_of_month, $current_month,
$current_year, $days_in_current_month, $show_history);
?>
</ul>
The helper then echoes my day values in my view. Is this good or bad practice? I kept thinking the wrong way when I wanted to start writing the code for this.. I wanted to have a function somewhere in my controller and then call it from the view, but I read that I shouldn't be doing it like that.. that I had to reverse my logic. I find it hard to wrap my head around the fact that I have to do this by sending arrays of data to my view (from my controller), so I opted for creating the helper. Good? Bad? Any tips, resources I should read, screencasts I should watch? Thanks a bunch.
This seems pretty straight forward to me. I don't really have time to write the whole thing now. but heres what steps I would take.
1) create a model which gets all the tasks for a month, and uses that to create an array of {date}=>{num_tasks} e.g. {'1'=>3,'2'=>1, "3"=>0, ...}. //hint: use a regular SQL count OR just loop thru and tally them.
2) create a controller function to return this array as JSON. Something like this:
public function get_month($month, $year) {
$tasks = $this->task_model->get_each_days_taskcount($month, $year);
$json = json_encode ($tasks);
echo $json;
}
3) write a html page which has a javascript function to call this controller function with AJAX. Something like:
function fill_calendar(month, year) {
$.get('some_controller/get_month/' + month + '/' + year, function(data) {
// parse the JSON then
// do something with the data here like $('#calendar').append();
});
}
4) Load this month with something like this:
$(function() {
var d = new Date();
var tmonth = d.getMonth();
var tyear = d.getFullYear();
fill_calendar(tmonth, tyear); // populate with this month
});
5) make the prev and next buttons work with something like
$('#prev_button').click(function() {
fill_calendar(current_month - 1 , tyear);
// you will probly need to make this calculation smarter than just minus 1
});
The key thing if you want your system to be dynamic is to make the data transmission short. So using Ajax, as icchanobot says, send the request for a specific month. Use get:
'some_controller?m=' + month + '&y=' + year
or even:
'some_controller?next' // or previous
The controller has to get data for the correct month, but not send back the whole month - only the data needed for your display, in a format as tight as possible. You could query how many events run on which days of that month:
SELECT day, count(event)
FROM event_table
WHERE DATE BETWEEN 'yyyy-mm-01' AND 'yyyy-mm-31'
GROUP BY day
ORDER BY day;
query needs adapting to your data structure - use a function to get the day from a complete date, and maybe use indexes so that the query returns the data fast.
Then the controller returns a string as short as you can make it, of the relevant data sorted in day order:
1=3,15=1,29=2
That would mean "1st=3 events, 15th=1 event, 29=2 events". If you don't want the number of events then "1,15,2" is enough. Empty days aren't transmitted.
the data is received by an ajax event handler on your web page and you parse it by using split, then populate the slider by using a loop.
Your biggest drag, in a very dynamic application, is if it slows down when you repeatedly ask for the next month and the next.
A few tricks:
Update the display while waiting for data; you send your query, and while it is being processed, you can slide the month into view, with the correct number of days, looking disabled so that the user knows immediately that they will get their data, and that it is in progress. Then when the data comes, populate and highlight. It will feel instant though it isn't.
Avoid processing information the user doesn't want anymore. If somebody clicks "next" three times, they want the data for july, not may, june and july. Don't process what you don't display.
Cache data you've already asked, unless you want the system to return dynamically to the server for the latest state of the calendar. You've asked for the data for May and June, but not displayed it; when the user hits "back", don't ask for that data again.
Good luck!
I really don't see the complication about this.......
If you just use the jQuery UI DataPicker and modify the js file so it stores the days in a slider, then put the data in a jQuery UI Slider and you should have almost what you require.
I'm trying to get twitter statuses displaying on my blog, however I cannot get the time each status is created at to display the way in which I desire. Here is how it is being printed now:
Thu Aug 05 12:36:20 +0000 2010
However I would like it to be displayed like this:
54 days ago
How can I manage this with PHP preg_replace?
Also at the moment I am using the twitter API to get the statuses. Is it better to use this method or an RSS feed? I would appreciate if anyone could help me out. Thanks
I would really recommend writing it out to the page as "Aug 5 2010" (or however you want it to appear). That way you only need to write it out once ever, not once per day. But also write as a GMT timestamp in a way that JS can read it but people that have JS turned off cannot see it. Then, once you've got your page displaying things correctly, use a JS script to loop through the tags and replace the dates with the friendly text you want. Example:
<span class="dateToBeReplaced" title="Thu Aug 05 2010 12:36:20 GMT+0000">Aug 05 2010</span>
The JS would look something like this (uses jQuery): http://jsfiddle.net/JxTLt/4/
JS is a little more finicky about date formats than PHP, so you pretty much should stick the the format above. Use strtotime() to handle the formatting and time zone conversion.
You don't need to manually parse the date, it's already in an understandable format. If you run it through strtotime it will return a timestamp that you can work with.
The concept of displaying time as you want is called "fuzzy time", and you can find a really code post on it here.
You won't be able to do this with preg_replace() alone. You need to do some temporal comparisons to create a human readable timestamp. Check out this post. Also keep in mind that Twitter responses will be GMT.
As far as the API vs. RSS, this is really up to you. Both responses have to be parsed. There is arguably more overhead with the API now that Twitter only supports OAuth. Although there are several PHP libraries available. If you only want to display statuses, I'd go with the RSS.
How can I create a calendar in PHP?
Today should be in bold. How could it be coded?
You can try dhtml Calendar, or maybe Yahoo UI's Calendar.
PHP: date should give you everything you need.
Then, format everything in a table.
Firstly, start by capturing your requirements (should it handle month browsing, should it show a week at a time, etc.) - this should let you derive a functional spec of sorts, which should guide you when actually writing the component/page/application
If you mean: "how to show a date picker on your web page from PHP", the answer is to use some default JavaScript library for it. E.g. Dojo or jQuery.
I want to show when the comment last posted in PHP. like 5 minutes ago, 2 days ago, 7 weeks ago. How to do this?
You can find plenty of answers with full solutions in different languages, pseudocode, ideas, etc.. here.
I believe there's an example of PHP too.
You can use timeago, a jQuery plugin, to do it via Javascript. It would yield the same result, update without refreshing, and by doing it client side instead of server side, you are not precluded from caching.
http://timeago.yarp.com/
Otherwise, Annurag has a link with some good PHP solutions.
You can do manual calculation in server, to get the time difference, then translate it into human time format.
Or my preference, do it in browser using javascript. Using this approach, the time in page can be updated without refresing the page.
You can use this jQuery EasyDate library to translate a DOM element into humane time format.
You can also read the comments in this post about Pretty Date by John Resig. It contain the code, and improvement by other.
Store the comment posted in the date DB and show the the same in the front end by comparing with current date and time using php function
