I was wondering how can I grab the value from a hidden field using PHP?.
Here is the hidden field.
<input type="hidden" name="delete" value="' . $row['delete_id'] . '" />
I understand this is a subjective question, so I apologize if it needs to be closed, but I feel like it comes up often enough for me to wonder if there is a general preference for one form over the other.
Obviously, the best answer is "refactor the code so you don't need to test for falsehood" but sometimes there's no easy way to do so and the "else" branch is simply to continue processing. So when you must have an "if not false" construct, which is the preferred standard:
The not operator
if(!value)
Or the test for false
if(value == false)
Hi,
I'm currently integrating facebook into my current app and I've succeeded in retrieving the access_token using the following code:
url="#{url}?#{client_id}&#{client_secret}&#{code}&#{redirect_uri}&type=client_cred"
agent = Mechanize.new
page = agent.get(url)
The page object above has a body which contains text something along the lines of
access_token=XXXXX
I just want to pull out the access_token value. I can get the entire string simply by writing:
page.body
But I was wondering is there a way to get the access_token value without resorting to regular expressions etc?
Thanks.
In the C++ Standard Library, std::string has a public member function capacity() which returns the size of the internal allocated storage, a value greater than or equal to the number of characters in the string (according to here). What can this value be used for? Does it have something to do with custom allocators?
this is my view code
<%=collection_check_boxes(nil, :admin_ids, Admin.all, :id, :name )%>
but when i try get the value in the controller i get always an empty value if the user doesnt check any item
and the length is always more than zero
when i write this code
arr = params[:admin_ids] ||= []
puts arr.length
ther arr.length is 1 even if the user doesnt select any of the items
how can i get an array of selected items only with no empty values
Does psycopg2 have a function for escaping the value of a LIKE operand for Postgres?
For example I may want to match strings that start with the string "20% of all", so I want to write something like this:
sql = '... WHERE ... LIKE %(myvalue)s'
cursor.fetchall(sql, { 'myvalue': escape_sql_like('20% of all') + '%' }
Is there an existing escape_sql_like function that I could plug in here?

The Microsoft.SqlServer.Management.Smo.SqlDataType enum has a value for the timestamp type but not rowversion. I'm looking for an updated version of the assembly or an alternate enum type that supports it.
The existing enum has a value for Timestamp, but according to the rowversion documentation, timestamp is "deprecated and will be removed in a future version". I prefer to avoid using deprecated things :)

Is it possible to get a value from the external CSS of a page if the element that the style refers to has not been generated yet? (the element is to be generated dynamically).
The jQuery method I've seen is $('element').css('property','value');, but this relies on element being on the page. Is there a way of finding out what the property is set to within the CSS rather than the computed style of an element?
I have a on a form of mine. I´m trying to reset the value (the value typed by the user) of this field on a certain event. However, I seem unable to access it both with .val() and .html().
