I would like to add a custom "trending topics" section to my news website at the top of the homepage. An existing example that shows precisely what I am looking for is the Daily Beast homepage.
I would like to do this with custom code or with a plugin, but not as a widget. Does anyone know how I can do this in a flexible way that can easily customize to style and look of my website.
My site is a Spanish language 24/7 news website called Yasta.pr. Thx!
it depends on how you are storing your data in your database but you can try this:
add a div section in the header of your webpage above the menu bar.
then you can dynamically add the most trending topic to it automatically when the page starts by inserting this code inside it:
<div id="*id_name">
$query = "SELECT * FROM *table_name ORDER BY *most_trending_column LIMIT 1";
mysql_select_db(*database_name, *connection);
$result = mysql_query($query) or die(mysql_error());
$data = mysql_fetch_assoc($result);
echo "<h3 id='*id_name'>" . $data['*title_column_name'] . "</h3>";
</div>
dont forget to connect to your database first.

I am using Goose to read the title/text-body of an article from a URL. However, this does not work with a twitter URL, I guess due to the different HTML tag structure. Is there a way to read the tweet text from such a link?
One such example of a tweet (shortened link) is as follows:
https://twitter.com/UniteAlbertans/status/899468829151043584/photo/1
NOTE: I know how to read Tweets through twitter API. However, I am not interested in that. I just want to get the text by parsing the HTML source without all the twitter authentication hassle.
Scrape yourself
Open the url of the tweet, pass to HTML parser of your choice and extract the XPaths you are interested in.
Scraping is discussed in: http://docs.python-guide.org/en/latest/scenarios/scrape/
XPaths can be obtained by right-clicking to element you want, selecting "Inspect", right clicking on the highlighted line in Inspector and selecting "Copy" > "Copy XPath" if the structure of the site is always the same. Otherwise choose properties that define exactly the object you want.
In your case:
//div[contains(#class, 'permalink-tweet-container')]//strong[contains(#class, 'fullname')]/text()
will get you the name of the author and
//div[contains(#class, 'permalink-tweet-container')]//p[contains(#class, 'tweet-text')]//text()
will get you the content of the Tweet.
The full working example:
from lxml import html
import requests
page = requests.get('https://twitter.com/UniteAlbertans/status/899468829151043584')
tree = html.fromstring(page.content)
tree.xpath('//div[contains(#class, "permalink-tweet-container")]//p[contains(#class, "tweet-text")]//text()')
results in:

What I am trying to achieve is to find a way of displaying a wiki page content in a floating iFrame ( and of course keep the styling ) for a tool that I am developing for our employees. Right now the tool I made is using jQuery dialog box to display a specific document / pdf, For compatibility and usability purposes I would really like to upgrade that so it uses a wiki page instead of documents / PDFs.The problem that I am facing is that there is no really direct link to the content of a Sharepoint wiki page instead the only available direct link is the one to the page all together with all the navigation menus, option panel, user panel etc. I want to avoid using javascrip to strip away these elements. Instead I am simply trying to find out if sharepoint 2013 has some more elegant way of providing the content such as: Web service or javascript SP API.
My ideas so far:
REST Url to give the content back? I know for sure it works for lists and libraries but I couldn't find anything in the REST API About wiki page content
SP.js ? Couldn't find anything about that either
Anyways, it could be possible that I have overlooked things, or probably haven't searched hard enough. However, any help is very very welcome. If you don't know about a concrete solution I would be very happy with nice suggestions too :)
If there is nothing out of the box I will have to get to my backup plan of a jQuery solution to get the page and strip off all unnecessary content and keep the styling.
I believe you are on the right track with REST API, in Enterprise Wiki Page the content is stored in PublishingPageContent property.
The following example demonstrates how to retrieve Enterprise Wiki Page content:
var getWikiPageContent = function (webUrl,itemId,result) {
var listTitle = "Pages";
var url = webUrl + "/_api/web/lists/GetByTitle('" + listTitle + "')/items(" + itemId + ")/PublishingPageContent";
$.getJSON(url,function( data ) {
result(data.value);
});
}
Usage
getWikiPageContent('https://contoso.sharepoint.com/',1,function(pageContent){
console.log(pageContent);
});
And something for those of you who like to have more than one different examples:
var inner_content;
var page_title = "home";
$.ajax({
url: "https://mysharepoint.sharepoint.com/MyEnterpriseWikiSite/_api/web/Lists/getbytitle('Pages')/items?$filter=Title eq '" + page_title +"'",
type: "GET",
headers: {
"ACCEPT": "application/json;odata=verbose"
},
success: function (data) {
if (data.d.results[0]) {
inner_content = data.d.results[0].PublishingPageContent;
}
},
error: function(){ //Show Error here }
});
That's what did the job for me.
This example fetches the inner content of an Enterprise wiki page by Title( make sure you are not using the Name of the page, although Title and Name can be given the same string value, they are different fields in sharepoint 2013 )
EDIT: If you are going to give a downvote, at least explain why -.-
Also, read comments if my post is still unclear. I tried to explain it a bit more in the comments but if it is still unclear about what I'm saying, let me know and I will take printscreens and explain using images.
I have created a model like so
class Post(models.Model):
title_of_post = models.CharField(max_length=100)
actual_post = models.TextField()
and I put this model in the admin interface and enabled the admin interface. Now, when I go to 127.0.0.1/admin/ and sign in, I can add this model. The posts created in the Post model can be seen on the homepage (127.0.0.1) so say my "title_of_post" is "title" and my "actual_post" is "the actual post", if I go to 127.0.0.1 I can see both the title and actual post on the homepage. The problem is, when I am in the admin interface and in the actual_post text box / TextField section, suppose I write this.
Something.
else
It would not recognize that I pushed the enter key after the period. I tried
Something. <br>
else
but that also didn't work. It does not go on a new line after the period. Is there any way to go to the next line when inputting information from the text box / TextField in the django admin interface? Is there any way to put headers from the admin interface, not from the template? Essentially, I want to be able to create this html from the admin interface.
<h1>Something.</h1> <br>
else
in order to show html inside a property, you need to place like this in your template:
{{ post.actual_post|safe }}
the safe template filter its good for not escaping html tags inside your template.
And this will print as:
Something
else
intead of:
Something <br /> else
Sitecore 6.6 Update 4
We're using CustomItemGenerator 1.0 and I was using this to help build a primary navigation menu for a site. This worked as expected and everything was rendered properly.
My problem is when I attempt to edit the menu via Page Editor; I don't even see the menu.
I use a repeater and repeat over a list of links to include in the nav. Due to the way the HTML was created, each LI element needs to have its own, specific ID ("Nav Id" Field in Sitecore) that ties into the CSS. Code inside of my repeater's ItemDataBound event:
// Cast the item using CustomItemGenerator-generated class
GenericContentPageItem navItem = (GenericContentPageItem)e.Item.DataItem;
liMenuItem.ID = navItem.NavId.Rendered; // I tried "navItem.NavId" by itself as well
So while this renders properly in the browser, it doesn't when I'm in Page Editor:
<li id="<input id='fld_B72EB6696DCF41A49671972D5EA5DEB8_2163B90C08AB4A18970A7F3ECE79DCFC_en_1_f71bd37d18d146c19e222e89fcffe278_3' class='scFieldValue' name='fld_B72EB6696DCF41A49671972D5EA5DEB8_2163B90C08AB4A18970A7F3ECE79DCFC_en_1_f71bd37d18d146c19e222e89fcffe278_3' type='hidden' value=" Home?="">
... instead of it rendering like this:
<li id="Home">...</li>
Now, that having been said, I can change my code to not use the CustomItemGenerator and it works fine in the browser and Page Editor as follows:
GenericContentPageItem navItem = (GenericContentPageItem)e.Item.DataItem;
Item nav = Sitecore.Context.Database.GetItem(navItem.ID);
liMenuItem.ID = nav.Fields["Nav Id"].ToString();
I would like to avoid having to hardcode field names in my code, which is why I am using CustomItemGenerator. Is there something that I'm doing wrong with my code that it doesn't want to work in Page Editor?
Thanks!
If you need the actual value out of the field regardless of if you are in the page editor or not, you want to use the Raw property:
liMenuItem.ID = navItem.NavId.Raw;
I'm building a website where the users to essentially "mark" things from another site -- e.g. they browse a third party's catalog, and once they hit an item they like, they somehow indicate to my site about that specific item (e.g. via the url). My initial thought was to have an iframe, a "mark" button on my own site in a little bar at the top, and the third party site in the iframe -- however, I found that it's impossible to get the url of an iframe if the user navigates away from the inital url. Is there any alternative to doing this?
You can retrieve html from another site, modify it and show to your user. Sure, you should have a grant from site owner and update your modifier for any html layout update. And you will need to resolve somehow all links from the page, including css, js and so on.
Iframe is not an option, you can't control the page in a frame in any way. That's security policy for all browsers.
(I know I'm a bit late but may be someone find it useful)
I had the same problem. I came to conclusion that only way to do that is creating proxy in PHP. And that's what I did (contents of "proxy.php" file):
<?php
$proxy = 'http://yoursite.com/proxy.php';
$host = parse_url($_GET['url'], PHP_URL_HOST);
$dir = $_SERVER[DOCUMENT_ROOT].'/cache_proxy/'.$host;
if(!is_dir($dir))
mkdir($dir);
$filepath = $dir.'/'.md5($_GET['url']);
if(is_file($filepath)){
include($filepath);
}else{
$page = file_get_contents($_GET['url']);
$page = preg_replace('/(a href)=[\'\"](http.*)[\'\"]/', '$1="'.$proxy.'?url=$2"', $page);
$page = preg_replace('/(a href)=[\'"][^http](.*)[\'"]/', '$1="'.$proxy.'?url=http://'.$host.'/$2"', $page);
$page = preg_replace('/(href|src)=[\'"][^http+](.*)[\'"]/', '$1="http://'.$host.'/$2"', $page);
file_put_contents($filepath, $page);
echo $page;
}?>
Now you can insert iframe with src="http://yoursite.com/proxy.html?url=http://othersite.com"
