I have an object in my database following a file upload that look like this
a:1:{s:4:"file";a:3:{s:7:"success";b:1;s:8:"file_url";a:2:{i:0;s:75:"http://landlordsplaces.com/wp-content/uploads/2021/01/23192643-threepersons.jpg";i:1;s:103:"http://landlordsplaces.com/wp-content/uploads/2021/01/364223-two-female-stick-figures.jpg";}s:9:"file_path";a:2:{i:0;s:93:"/var/www/vhosts/landlordsplaces.com/httpdocs/wp-content/uploads/2021/01/23192643-threepersons.jpg";i:1;s:121:"/var/www/vhosts/landlordsangel.com/httpdocs/wp-content/uploads/2021/01/364223-two-female-stick-figures.jpg";}}}
I am trying with no success to parse extract the two jpg urls programmatically from the object so i can show the images ont he site. Tried assigning parse(object) but that isnt helping. I just need to get the urls out.
Thank you in anticipation of any general direction
What you're looking at is not a JSON string. It is a serialized PHP object. If this database entry was created by Forminator, you should use the Forminator API to retrieve the needed form entry. The aforementioned link points to the get_entry method, which I suspect is what you're looking for (I have never used Forminator), but in any case, you should look for a method that will return that database entry as a PHP object containing your needed URLs.
In case it is ever of any help to anyone the answer to the question was based on John input. The API has the classes to handle that without needing to understand the data structure.
Forminator_API::initialize();
$form_id = 1449; // ID of a form
$entry_id = 3; // ID of an entry
$entry = Forminator_API::get_entry( $form_id, $entry_id );
$file_url = $entry->meta_data['upload-1']['value']['file']['file_url'];
$file_path = $entry->meta_data['upload-1']['value']['file']['file_path'];
var_dump($entry); //contains paths and urls
Hope someone benefits.

I am currently working on external app using Google Sheets and JSON for data transmission via Fetch API. I decided to mock the scenario (for debugging matters) then simple JSON comes from my external app through prepared Code.gs to be posted on Google sheets. The code snippet I run through Apps-scripts looks like this:
function _doPost(/* e */) {
// const body = e.postData.contents;
const bodyJSON = JSON.parse("{\"coords\" : \"123,456,789,112,113,114,115,116\"}" /* instead of : body */);
const db = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
db.getRange("A1:A10").setValue(bodyJSON.coords).setNumberFormat("#"); // get range, set value, set text format
}
The problem is the result I get: 123,456,789,112,113,000,000,000 As you see, starting from 114 and the later it outputs me 000,... instead. I thought, okay I am gonna explicitly specify format to be returned (saved) as a text format. If the output within the range selected on Google Sheets UI : Format -> Number -> it shows me Text.
However, interesting magic happens, let's say if I would update the body of the JSON to be parsed something like that when the sequence of numbers composed of 2 digits instead of 3 (notice: those are actual part of string, not true numbers, separated by comma!) : "{\"coords\" : \"123,456,789,112,113,114,115,116,17,18\"}" it would not only show response result as expected but also brings back id est fixes the "corrupted" values hidden under the 000,... as so : "{"coords" : "123,456,789,112,113,114,115,116,17,18 "}".
Even Logger.log() returns me initial JSON input as expected. I really have no clue what is going on. I would really appreciate one's correspondence to help solving this issue. Thank you.
You can try directly assigning a JSON formatted string in your bodyJSON variable instead of parsing a set of string using JSON.parse.
Part of your code should look like this:
const bodyJSON = {
"coords" : "123,456,789,112,113,114,115,116"
}
I found simple workaround after all: just added the preceding pair of zeros 0,0,123,... at the very beginning of coords. This prevents so called culprit I defined in my issue. If anyone interested, the external app I am building currently, it's called Hotspot widget : play around with DOM, append a marker which coordinates (coords) being pushed through Apps-script and saved to Google Sheets. I am providing a link with instructions on how to set up one's own copy of the app. It's a decent start-off for learning Vanilla JavaScript basics including simple database approach on the fly. Thank you and good luck!

With a lot of help from people in this site, I managed to get some Json data from an amazon page. The data, for example, looks like this.
https://jsoneditoronline.org/?id=9ea92643044f4ac88bcc3e76d98425fc
First I have a list of strings which is converted to a string.
script = response.xpath('//script/text()').extract()
#For example, I need the variationValues data
variationValues = re.findall(r'variationValues\" : ({.*?})', ' '.join(script))[0]
Then, in my code, I have this (not a great name, will be changed later)
variationValuesJson = json.loads(variationValues)
variationValuesJson is in fact a dictionary, so doing something like this
variationValues["size_name"][3]
Should return "5.5 M US"
My issue is that, when running the program, I get the string indices must be integers error. Anyone knows whats wrong?
Note: I have tried using 'size_name' instead of "size_name", same error
variationValues["size_name"][3] #this is the raw string which you have converted to variationValuesjson
I think this is not what you actually want.
Your code should be this.
variationValuesJson['size_name'][3] #use variationValuesjson ;)
I am working on page which is going to present 20 products. I would like to avoid using any db(page is going to be simple) so I am thinking about storing products' data in [globals] array. Case is that each product description is quite long between 500 and 1000 words and it is formatted which makes this very complicated. I am wondering if is possible to use similiar to nowdoc from php method to manage such long texts in free-fat-framework frane(http://www.php.net/manual/en/language.types.string.php#language.types.string.syntax.nowdoc)
Do you have any other idea to store long text in arrays in 3f?
Thanks in advance
Macrin
The user guide has an example of a very long string:
[globals]
str="this is a \
very long \
string"
Me, I would keep each product's description (with any other info, like photo url or price) in a seperate text file in a dedicated directory (let's say products). Then in index.php or any other route handler I would scan this directory and load the descriptions:
$productsDir = dir(__DIR__ . '/products');
$productsInfo = [];
foreach (new DirectoryIterator($productsDir) as $fileInfo) {
if($fileInfo->isDot()) continue;
$productsInfo[] = file_get_contents($fileinfo->getPathname());
}
var_dump($productsInfo);
You can use the JIG database and its data mapper.
https://fatfreeframework.com/3.6/jig-mapper
It can store your product items in plain .json files and you also get some basic CRUD and search functionality. You can also hook in Cortex later, if you ever want to upgrade to a real DB.
I want to encrypt a URL variable so that the user can't see or modify the information when it is passed in jsp.
This is an example URL:
localhost/somewebpage/name.jsp?id=1234&tname=Employee_March_2013
Here I want to encrypt or encode the parameters id and tname.
Could someone please help me write a short script that encodes / encrypts and then decrypts the parameters
EDIT:
I am sending this url as a attachment in email... when receiver clicks on this link their payslip information will displayed on the web page'
The best way to encode / decode in Base64 without using any third party libraries, you can use Using sun.misc.BASE64Encoder / sun.misc.BASE64Decoder.
try this snippet
String id="1234";
byte[] bytesEncoded = Base64.encodeBase64(id.getBytes());//encoding part
String encoded_id=new String(bytesEncoded);
String id1=request.getParameter("id");
byte[] valueDecoded= Base64.decodeBase64(id1);//decoding part
String decoded_id=new String(valueDecoded);
Send 'encoded_id' as a url parameter instead of passing 'id'
Your question became solvable the moment we knew that you are 'sending this url as attachment in email... when receiver click on this link their payslip is confirmed'
That means there are 3 options: encrypting, hashing and using random string(s).
In this case I recommend the random strings (or hashing) instead of encrypting. The reason is 2-fold:
You are not sending out potentially private data (for google gmail to read, for example)
random string(s) (or hashing) is simpler, shorter and safer (for this case).
Assuming you have a database containing your user-data, then you'd generate a unique random string (or hash) for that specific user/transaction. Then you store this data (you could hash it again internally) together with or linked to your user-data.
Now you only send out the link with the random string(s)/hash that is uniquely linked to the user-data.
Have a look on SO for https://stackoverflow.com/search?q=[jsp]+hash
and please, for the love of [enter deity here], be sure you read Wikipedia about 'salt' etc.!!
You do not want to make mistakes with user-payments!
Now, make a choice, set it up and return with questions should you get stuck!
EDIT:
In fact.. instead of hashing, a completely 'random' (fixed length) unique string(s) is sufficient! Better yet: or two random strings, for a two-factor check: one string for identification, one for authentication.
URLEncoder.encode(Encryption.encrypt(parameters), "UTF-8")
Always use POST method.
And even in POST method, user can see the id and can change it in browser console network tab.So that, user can see other's email attachment since you mentioned in your comment like that.
So, try to set id in jsp session and get the id in the java servlet code.
it is really good practice.
Let's say you want to construct an Iterator that spits out File objects. What type of data do you usually provide to the constructor of such an Iterator?
an array of pre-constructed File objects, or
simply raw data (multidimensional array for instance), and let the Iterator create File objects on the fly when Iterated through?
Edit:
Although my question was actually ment to be as general a possible, it seems my example is a bit to broad to tackle general, so I'll elaborate a bit more. The File objects I'm talking about are actually file references from a database. See these two tables:
folder
| id | folderId | name |
------------------------------------
| 1 | null | downloads |
file
| id | folderId | name |
------------------------------------
| 1 | 1 | instructions.pdf |
They reference actual folders and files on a filesystem.
Now, I created a FileManager object. This will be able to return a listing of folders and files. For instance:
FileManager::listFiles( Folder $folder );
... would return an Iterator of File objects (or, come to think of it, rather FileReference objects) from the database.
So what my question boils down to is:
If the FileManager object constructs the Iterator in listFiles() would you do something like this (pseudo code):
listFiles( Folder $folder )
{
// let's assume the following returns an multidimensional array of rows
$filesData = $db->fetch( $sqlForFetchingFilesFromFolder );
// let the Iterator take care of constructing the FileReference objects with each iteration
return FileIterator( $filesData );
}
or (pseudo code):
listFiles( Folder $folder )
{
// let's assume the following returns an multidimensional array of rows
$filesData = $db->fetch( $sqlForFetchingFilesFromFolder );
$files = array();
for each( $filesData as $fileData )
{
$files.push ( new FileReference( $fileData ) );
}
// provide the Iterator with precomposed FileReference objects
return FileIterator( $files );
}
Hope this clarifies things a bit.
What is your "File" object meant to be? An open handle to a file, or a representation of a file system path which can be opened in turn?
It would generally be a bad idea to open all the files at once - after all, part of the point of using an iterator is that you only access one object at a time. Your iterator could yield one open file at a time, and let the caller take responsibility for closing it, although again that might be slightly odd to use.
Your requirements aren't clear, to be honest - in my experience, most iterators which yield a series of files use something like Directory.GetFiles(pattern) - you don't pass them the raw data at all, you pass them something which they can use to find the data for you.
It's not obvious what you're trying to get at - it feels like you're trying to ask a general question, but you haven't provided enough information to let us advise you. It's like asking, "Do I want to use a string or an integer?" without giving any context.
EDIT: I would probably push all of that logic into FileIterator, personally. Otherwise it's hard to see what value it's really providing. In a language like C# or Python you wouldn't need a separate class in the first place - you'd just use a generator of some description. In that sense this question isn't language agnostic :(
What exactly is your iterator supposed to do? Write data to files? Create them?
An iterator is a pattern for iterating through data, which means providing sequential data in a uniformous way, not mutating them.
I find the question to be unclear.
Are we talking Iterator or Factory?
To me an Iterator is operating on a pre-existing collection of things and allows the caller to work on each thing in turn.
When you say "Spits Out" do you mean allows the client to work with one file from a pre-existing set of files or do you mean that you are iterating some data and intend to store that data in files you are generting. If we are geneating, then we've got a File factory.
My guess is that you are intending to process some files in a file sytstem. I think that your Iterator is akin to a Directory, it can give you the next file it knows about. So I construct the "Driectory" by passing enough data to allow it to know which files you mean (could be just an OS path, could be some kind of "find" enxpression, a list of ftp-like references, etc.) and expect it to give me the next File as I iterate.
----updated following question clarification
I think that the key question here is when the individual files should be opened. The Iterator itself will reasonably return a File object corresponding to an open file handle, the caller can then just work with the file. But iternally should the iterator be working against a list of pre-opened files or a list of file references, the files being opened as the iterator next() is used.
I think we should do the latter, because there is overhead in having an open file, hence we should open the files only when we need them.
That leads to one other point: who closes the file? We can't afford to keep them all open. Perhaps the iterator should close each file as next() is called. This implies that that the iterator itself needs a close() method to allow tidy up of the currently open file. Alterntaivelywe need to explictily document that closing is the client's responsibility.
