I'm retrieving an array of my users' friends' ids using open graph api.
$friends = $facebook->api('/me/friends?limit=2000');
$friendsList = array();
foreach ($friends as $key=>$value)
{
foreach ($value as $fkey=>$fvalue) {
$friendsList[] = $fvalue[id];
}
}
The problem I have is that no matter what I put in the limit, I only receive a max of 500 friend id values for users that have more than 500 friends. I have been reading up on limits and pagination in Facebook Developers information with no luck.
Any ideas on what I need to do to retrieve all user's friend ID's? Why does the last value in the array show as "h"? All other values are id's.
THANKS!!!
Why does the last value in the array show as "h"?
Because you are doing a loop in a loop.
In the outer loop, you iterate over the two properties of the actual API response – data and paging.
And then, in the inner loop, you go through each of the arrays these properties point to. That’s a lot of results in the form of name and id; and then the second time the inner loop goes through the array that the paging property points to, and that has only one property that has the name/key next and the value https://graph.facebook.com/…
Now, since you are trying index-based access on the first value with $fvalue[id], since $fvalue contains actually the text literal https://graph.facebook.com/…, and there is no contant named id declared, PHP first interprets that as if "id" was ment, and then converts this string value to integer 0 for index-based access on $fvalue. And that gets you – since PHP also allows access to bytes (not characters) in a string variable index-based – the first byte, whose ASCII representation is the character h …
So, what you want to do is loop actually just once, but directly over the contents of $friends['data'].
If you just need facebook id then you should try with just id field, it should return all the friends id. with this I remember my app has handled a user with 1500 friends.
$friends = $facebook->api('/me/friends?fields=id');

I have an html form which sends a hidden field and a radio button with the same name.
This allows people to submit the form without picking from the list (but records a zero answer).
When the user does select a radio button, the form posts BOTH the hidden value and the selected value.
I'd like to write a perl function to convert the POST data to a hash. The following works for standard text boxes etc.
#!/usr/bin/perl
use CGI qw(:standard);
sub GetForm{
%form;
foreach my $p (param()) {
$form{$p} = param($p);
}
return %form;
}
However when faced with two form inputs with the same name it just returns the first one (ie the hidden one)
I can see that the inputs are included in the POST header as an array but I don't know how to process them.
I'm working with legacy code so I can't change the form unfortunately!
Is there a way to do this?

That's an odd approach. It would be easier to leave the hidden input out and treat the absence of the data as a zero answer.
However, if you want to stick to your approach, read the documentation for the CGI module.
Specifically, the documentation for param:
When calling param() If the parameter is multivalued (e.g. from multiple selections in a scrolling list), you can ask to receive an array. Otherwise the method will return the first value.
Thus:
$form{$p} = [ param($p) ];
However, you do seem to be reinventing the wheel. There is a built-in method to get a hash of all paramaters:
$form = $CGI->new->Vars
That said, the documentation also says:
CGI.pm is no longer considered good practice for developing web applications, including quick prototyping and small web scripts. There are far better, cleaner, quicker, easier, safer, more scalable, more extensible, more modern alternatives available at this point in time. These will be documented with CGI::Alternatives.
So you should migrate away from this anyway.
Replace
$form{$p} = param($p); # Value of first field named $p
with
$form{$p} = ( multi_param($p) )[-1]; # Value of last field named $p
or
$form{$p} = ( grep length, multi_param($p) )[-1]; # Value of last field named $p
# that has a non-blank value
In jasper I have to print a collection without knowing in advance the keys, because they are programmatic and can change over time. Let me do an example of this list:
formData[0]={addictions=1, workout=0, allergies=1, selfSufficiency=0}
formData[1]={gastricNose=1, weightChange=1, diet=XXXX}
[...]
formData[12]={dailyAmount=12, latestDate={type=date, value=1542582000000}, ostomy=1, ostomyType=AA, ostomyBag=BB}
How can I print a list of all these keys/values so that they get all listed properly like this? I can already print these objects raw in a list but they obviously look pretty much like the example I wrote above, while instead I need jasper to cycle through each of the elements by itself and retrieve the keys and the value for each element.
This is what I'm trying to print:
addictions: 1
workout: 0
[...]
gastricNose: 1
weightChange: 1
[...]
dailyAmount: 12
latestDate: 18/11/2018
[...]
In all posts I've looked into I'm required to know at least the name of the keys, but in my case I can't. And I cannot modify the data source structure either (for instance formatting the collection to be {key:"addictions",value:"1"} can't do that).
Thanks for your hints
I have an ABAP program that sends emails. A sent email is stored in SOOD table. After sending an email I would like to get some ID of the email to be able to check its status later (in SOST table). I have seen more functions/methods to send email (e.g. cl_bcs/send, SO_NEW_DOCUMENT_SEND_API1), but none of them returns any ID. Is there a reliable way to get it?
Function module SO_NEW_DOCUMENT_SEND_API1 create and export a new OBJECT_ID for every new message sent, As you can see in here -
This NEW_OBJECT_ID stored at BCST_SR table in SCOM_KEY field. From BCST_SR table you've to get DOC_OID, using DOC_OID you can get details from SOOD table. (Reference field in SOOD is - IF_DOC_BCS ) Then use the Object number OBJNO to get the details from SOST table.
Also you can refer t-code SBWP to check your mail status.
For class CL_BCS, you can check the send_request object's method doc_wrapper_id. This will return the sood structer.
Two other answers gave me together valuable clues to get it done (+1). But both missed some accuracy and code snippets, so I sum it all up in my answer.
using cl_bcs
DATA gr_send_request TYPE REF TO cl_bcs.
DATA emailid LIKE soodk.
gr_send_request = cl_bcs=>create_persistent( ).
" ...
CALL METHOD gr_send_request->send(EXPORTING i_with_error_screen = 'X'
RECEIVING result = gv_sent_to_all ).
IF gv_sent_to_all = 'X'.
emailid = gr_send_request->send_request->doc_wrapper_id( ).
ENDIF.
SOODK (not sood) is structure containing three components (OBJTP, OBJYR, OBJNO) which are together the key in SOOD table.
using SO_NEW_DOCUMENT_SEND_API1
DATA LT_OBJECTID TYPE SOFOLENTI1-OBJECT_ID.
CALL FUNCTION 'SO_NEW_DOCUMENT_SEND_API1'
EXPORTING
DOCUMENT_DATA = LT_MAILSUBJECT
DOCUMENT_TYPE = 'HTM'
IMPORTING
new_object_id = lt_objectid
" ...
lt_objectid (SOFOLENTI1-OBJECT_ID) is char(17), that contains concatenated SOODK structure OBJTP+OBJYR+OBJNO. When divided to parts, it can be used to lookup a record in SOODK table. (I didn't find it in BCST_SR-SCOM_KEY, but it was not necessary.)
I am using facebook graph api to search the keywords, like as follows
https://graph.facebook.com/search?q='test'&limit=60&access_token=(myAccessToken)
Which works fine and returns the data correctly.
But I want to search with multiple keywords (Eg . I need the post which contains the words 'test' or 'date')
I tried in the following way, which is working but returns the array which contains the words test and date. It doesn't return the results of individual words.
https://graph.facebook.com/search?q=test|date&limit=60&access_token=
(myAccessToken)
Is it possible to implement graph api search with multiple keywords in "OR" condition?
If so explain how?
I know that is one year later but did you manage to find a solution? I've tried with different methods, like putting " | " character, but nothing works. I'm wondering to give it a try to batch request, passing on each query each keyword that I'm interested in and loop later through the responses to filter repeated results.
You can use FQL. For example if you have two different artists pages and you want to get information about both:
$fql = 'SELECT name,fan_count,page_id,hometown,record_label from page WHERE name="Rihanna" OR name="Jay z" LIMIT 2';
$ret_obj = $facebook->api(array('method' => 'fql.query','query' => $fql));
foreach( $ret_obj as $var)
{
var_dump($var);
}
This code will return you an array that has the required information about both artists.
I've research this topic extensibly and I'm asking as a last resort before assuming that there is no wildcard for what I want to do.
I need to pull up all the text input elements from the document and add it to an array. However, I only want to add the input elements that have an id.
I know you can use the \S* wildcard when using an id selector such as $(#\S*), however I can't use this because I need to filter the results by text type only as well, so I searching by attribute.
I currently have this:
values_inputs = $("input[type='text'][id^='a']");
This works how I want it to but it brings back only the text input elements that start with an 'a'. I want to get all the text input elements with an 'id' of anything.
I can't use:
values_inputs = $("input[type='text'][id^='']"); //or
values_inputs = $("input[type='text'][id^='*']"); //or
values_inputs = $("input[type='text'][id^='\\S*']"); //or
values_inputs = $("input[type='text'][id^=\\S*]");
//I either get no values returned or a syntax error for these
I guess I'm just looking for the equivalent of * in SQL for JQuery attribute selectors.
Is there no such thing, or am I just approaching this problem the wrong way?
Actually, it's quite simple:
var values_inputs = $("input[type=text][id]");
Your logic is a bit ambiguous. I believe you don't want elements with any id, but rather elements where id does not equal an empty string. Use this.
values_inputs = $("input[type='text']")
.filter(function() {
return this.id != '';
});
Try changing your selector to:
$("input[type='text'][id]")
I figured out another way to use wild cards very simply. This helped me a lot so I thought I'd share it.
You can use attribute wildcards in the selectors in the following way to emulate the use of '*'. Let's say you have dynamically generated form in which elements are created with the same naming convention except for dynamically changing digits representing the index:
id='part_x_name' //where x represents a digit
If you want to retrieve only the text input ones that have certain parts of the id name and element type you can do the following:
var inputs = $("input[type='text'][id^='part_'][id$='_name']");
and voila, it will retrieve all the text input elements that have "part_" in the beginning of the id string and "_name" at the end of the string. If you have something like
id='part_x_name_y' // again x and y representing digits
you could do:
var inputs = $("input[type='text'][id^='part_'][id*='_name_']"); //the *= operator means that it will retrieve this part of the string from anywhere where it appears in the string.
Depending on what the names of other id's are it may start to get a little trickier if other element id's have similar naming conventions in your document. You may have to get a little more creative in specifying your wildcards. In most common cases this will be enough to get what you need.
