hashtag

I am pretty sure there should be a way to search for hashtags using Full-Text index in MyISAM table. Default setup would do the following: textfield hashtag #hashtag #two #hashtag #hashtag SELECT * FROM table WHERE MATCH(textfield) AGAINST ('#hashtag') > | hashtag | > | #hashtag | > | #two #hashtag #hashtag | While it should return only 2nd and 3rd rows instead. It looks like hashtag is treated as a word delimiter, so it is "removed" before the search begins. What should I do to enable indexing and searching for terms containing # as part of the word? As documented under Fine-Tuning MySQL Full

I want to replace hash tags in string with the same hash tag but after adding link to it Example: $text = "any word here related to #English must #be replaced." I want to replace each hashtag with #English ---> <a href="bla bla">#English</a> #be ---> <a href="bla bla">#be</a> So the output should be like that: $text = "any word here related to <a href="bla bla">#English</a> must <a href="bla bla">#be</a> replaced." $input_lines="any word here related to #English must #be replaced."; preg_replace("/(#\w+)/", "<a href='bla bla'>$1</a>", $input_lines); DEMO OUTPUT : any word here related to <a

I am having a really hard time figuring out a regular expression (in C#) to validate hashtags. \w simply isn't enough as special characters are missing (ä, ö, ø, æ, å for starters, but also a lot of other foreign characters. I need to support ALL hashtags there is. Mainly from Twitter, but in the future also from other providers. My best shot (so far) is: ^#[a-zA-Z_0-9\u00C0-\u02AF]+$ (C# regex) I cannot find any decent documentation from Twitter or anyone else about this, so: Does anyone know of any documentation I have missed? OR does anyone know which unicode ranges I should include as

I'm trying to use AngularJS $anchorScroll with $location.hash . However, when I set the hash, AngularJS adds a forward slash, / after it. For example, the url is: http://localhost:13060/Dashboard . When I don't include the AngularJS library, I can click the link, #contact , and go to http://localhost:13060/Dashboard#contact . But when I include AngularJS and click the link, it goes to http://localhost:13060/Dashboard#/contact preventing $anchorScroll from working. Edit $anchorScroll not working The starting URL is http://localhost:13060/Category . When I add a category, it should go to http:/

When I visit my_site.com/page.php#something , the scroll position is the one of the element carrying this particular hashtag rather than the top of the page. Executing window.scrollTo(0, 0); doesn't change this fact. What can then? EDIT: also tried accepted answer from How to disable anchor "jump" when loading a page? . Doesn't seem to work anymore. What you have to do is store the hashtag for later use and then delete it so that the browser doesn't have anything to scroll to. It is important that you do not put that part of the code in the $() or $(window).load() functions as it would be to

In developing an iOS app containing a twitter client, I must allow for user generated hashtags (which may be created elsewhere within the app, not just in the tweet body). I would like to ensure any such hashtags are valid for twitter, so I would like to error check the entered value for invalid characters. Bear in mind that users may be from non-English speaking countries. I am aware of the usual limitations, such as not beginning a hashtag with a number, and no special punctuation characters, but I was wondering if there is a known list of all additional characters that are technically

database design question here. Say we had a webapp or something that uses hashtags for 20-40 word notes. What is the best way to store a user's hashtags. For instance, if a user entered. "I like to have #lunch at #sizzler" we would store the sentence as text and we could store the hashtags as JSON, a comma separated list or some other mechanism. Its also worth pointing out that the tags need to be searchable, such as how many people have been hash tagging lunch, etc. Advise on the matter would be great, I always get a bit stumped when it comes to storing variable sized inputs in mysql. There

I need to get some pictures which have a specific hashtag using PHP ? Any help will be awesome, or hint ? Anirudh Ramanathan There is the instagram public API's tags section that can help you do this. Here's another example I wrote a while ago: <?php // Get class for Instagram // More examples here: https://github.com/cosenary/Instagram-PHP-API require_once 'instagram.class.php'; // Initialize class with client_id // Register at http://instagram.com/developer/ and replace client_id with your own $instagram = new Instagram('CLIENT_ID_HERE'); // Set keyword for #hashtag $tag = 'KEYWORD HERE'; //
