Apologies if this has already been asked.
I am working on a project where I am looking to display locations of a business. This can be either by state, or by city (in a state).
I am trying to work with these two routes:
GET /#state
GET /#city-#state
#state works well, but when I try to navigate to a #city-#state page, I get errors because it is trying to load the #state page, and cannot find the required data.
Looking at base.php, I found that the preg_match_all is matching with \w, so it should be ignoring the hyphen(-), but for some reason isn't.
I need the URLs to be in this structure.
Can someone help me notice what I am missing?
Thanks!
I don't think F3 allows you to use a dash to separate tokens in a url; hence why it's always matching the first token (#state).
The regex used to grab tokens is '/#(\w+)/', it wants a slash character to separate tokens.
I would suggest using /#state and /#city/#state.

first question in a long while! I need to find any and all urls's in a string returned from a facebook page request (I'm requesting the website of a page using the graphi api) and putting the value into an array that I subsequently display in a datatable js table.
Anyhow, I'm having issues as when I build the json data for the datatable, it breaks in some cases:-
http://socialinsightlab.com/datatable_fpages.json
The issue is with the website field having erroneous characters / structure / white space etc in the field.
Anyhow I found the perfect regex to use to find all websites in the field (there can be more than one website listed in the return).
The regex is
(?i)\b((?:[a-z][\w-]+:(?:\/{1,3}|[a-z0-9%])|www\d{0,3}[.]|[a-z0-9.\-]+[.][a-z]{2,4}\/)(?:[^\s()<>]+|\(([^\s()<>]+|(\([^\s()<>]+\)))*\))+(?:\(([^\s()<>]+|(\([^\s()<>]+\)))*\)|[^\s`!()\[\]{};:'".,<>?«»“”‘’]))
When I try and assign it to a php variable as in preg_match_all I can't as it won't accept the regex string into the variable as it has quotes in it I guess.
So my question is how can I extract only the urls found in the website field and then assign them to a variable so i can add them to the datatable.
Here is an example of a call that fails:-
http://socialinsightlab.com/datatable_fpages.json
I need to be able to just return websites and nothing more.
Any ideas?
Thanks

This regex is specifically made as a solution to this problem:
(?:https?:\/\/|www)[^"\s]+
Live demo
If you don't want to deal with all this quotes escaping, you can do the following:
Save regex to a file, say, regex.txt.
Read this file into variable and trim: $regex = trim(file_get_contents("regex.txt"));
Use it with preg_match() etc.
I'm working on redirecting people if they type a "not really wrong url".
For example I have a good URL http://www.website.com/category/foo-bar-if-bar-foo/.
This one works so if a user enter to my website with it, I can retrieve the article corresponding.
But if someone enter to my website with a not really wrong url like http://www.website.com/category/foo-bar-foo/ because an another website has referenced a wrong url, I should redirect him to the right one instead of having a 404 status code...
So how should I do this? and Most important, should I do this ?
I actually use Eloquent with Laravel 4.2.
Thank you in advance.
EDIT
I was wrong about stackoverflow, thanks for your comment. It uses the unique ID of a post.
EDIT 2
I Looked at SOUNDEX function in SQL, it's really good if there is a small difference like a character or two missing. But if my url is as broken as my example, it's not working anymore obviously. But thanks it's gonna be usefull.
Just thinking off the top of my head, you could create a SQL table (with Full-Text indexing enabled) containing all your paths (it might already exist).
In the event that a 404 is triggered, hijack that and do a MATCH (Full Text Search) and return the path with the highest scoring MATCH (you can also consider using a score threshold to prevent nonsensical matches).
I'm really a major novice at RegEx and could do with some help.
I have a long string containing lots of URL's and other text, and one of the URL's contains has /find/ in it. ie:
1. http://www.example.com/not/index.html
2. http://www.example.com/sat/index.html
3. http://www.example.com/find/index.html
4. http://www.example.com/rat/mine.html
5. http://www.example.com/mat/find.html
What sort of RegEx would I use to return the URL that is number 3 in that list but not return me number 5 as well? I suppose basically what I'm looking for is a way of returning a whole word that contains a specific set of letters and / in order.
TIA
I would assume you want preg_match("%/find/%",$input); or similar.
EDIT: To get the full line, use:
preg_match("%^.*?/find/.*$%m",$input);
I can suggest you to use RegExr to generate regular expressions.
You can type in a sample list (like the one above) and use a palette to create a RegExp and test it in realtime. The program is available both online and as downloadable Adobe AIR package.
Unfortunately I cannot access their site now, so I'm attaching the AIR package of the downloadable version.
I really recommend you this, since it helped a RegExp newbie like me to design even the most complex patterns.
However, for your question, I think that just
\/find\/
goes well if you want to obtain a yes/no result (i.e. if it contains or not /find/), otherwise to obtain the full line use
.*\/find\/.*
In addition to Kolink's answer, in case you wanted to regex match the whole URI:
This is by no means an exhaustive regex for URIs, but this is a good starting point. I threw in a few options at key points, like .com, .net, and .org. In reality you'll have a fairly hard time matching URIs with regular expressions due to the lack of conformity, but you can come very close
The regex from the above link:
/(https?:\/\/)?(www\.)?([a-zA-Z0-9-_]+)\.(com|org|net)\/(find)\/([a-zA-Z0-9-_]+)\.(html|php|aspx)?/is
Im using php to develop an application, but I am running into some issues with regex...
I found a few sites that explain it, but it is for some reason over my head? can someone please help explain regex arguements?
I uploaded a sample of what I am working on here...
First, click on the "+" button at top right to get to the add content view.
Basically, I need it so when you submit from this form, php will check that the values are formatted correctly.
Domain: this can be .com, .co, .biz, .info, etc... User can enter the prefix, like a url, and php gets rid of it... so the ending strings in the array are just domain.com
domain1.com
somedomain.biz
mydomain.co
Redirect: with this one, php uses the ',' so we are left with the ip, and the domainkey as seperate strings, the ip can be 2-3 numbers per section!, so ###.##.##.###, or even ##.##.##.##, and the domain key is a varchar(not so important)
##.##.##.##, domainkey
###.###.###.###, domainkey
Solution for redirect:
(\d{1,3}\.){3}\d{1,3}
/24's: this is similar to the redirect IP, but the end will always end in '0/24'
##.##.###.0/24
##.##.###.0/24
Names:* This one should be the easiest, it can only be letters, no numbers... any length... *

May I suggest using some software or even website that allows you to test your regex. Such as:
The Regex Coach
Regexpal
RegExr
Expresso
RegexDesigner
etc
It really depends on how strict you want to get with it and how fancy you want to make your regex.
/((\d{1,3}).){3}(\d{1,3})(\/\d{2})?/
I have a website which allows users to submit photos of wildlife. Once uploaded, they can identify the specie on the photo, for example "Polar bear".
This triggers me to get information from Wikipedia about that specie, using that search term:
$query = "http://en.wikipedia.org/w/api.php?action=query&rvprop=content&format=json&titles=" . $query;
$pages = file_get_contents($query);
Such a query returns one of the following:
An array of pageids, which I can then query for that page's content
Nothing, because there simply isn't any match
a REDIRECT result, which allows me to resolve the page with the proper name
The problem I have has to do with casing. For example, the search term "Milky stork", returns nothing, not even a redirect. "Milky Stork" does work. Uppercasing each word in the query is not a solution either, as it could be that some pages are in lowercase, whereas the uppercase query does not work. There's no consistency.
I'm looking for a way to make this more robust. It shouldn't be that a query fails because of wrong casing, which cannot even be predicted on the user's side.
Does anyone know of a solution for this? Other than trying every possible combination of casings?
Note: Some may suggest to use dbpedia instead, but this is no solution for my total needs.
Unfortunatelly, there is no easy solution - read http://www.mediawiki.org/wiki/API:Opensearch#Note_on_case_sensitivity
You can try instead use opensearch to find appropriate casing (if normal query returns nothing usable):
http://en.wikipedia.org/w/api.php?action=opensearch&search=milky+stork&namespace=0&suggest=
will give you
["milky stork",["Milky Stork"]]
I think trying every possible combination is a viable solution. So, your query might look like:
http://en.wikipedia.org/w/api.php?action=query&rvprop=content&format=json&titles=Milky stork|Milky Stork
Note that the first letter is not case-sensitive on Wikipedia.
