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

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 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.
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 recently took an interest in retrieving data in R through JSON. Specifically, I want to be able to access data through the IMF. I know virtually nothing about JSON so I will share what I [think I] know so far, and what I have accomplished.
I browsed their web page for JSON, which helped a little bit. It gave me the start point URL. Here is the web page; http://datahelp.imf.org/knowledgebase/articles/667681-using-json-restful-web-service
I managed to download (using the GET() and the fromJSON() functions) some lists, which are really bulky. I know enough about the lists that the "call" was successful, but I cannot for the life of me get actual data. So far, I have been trying to use the rawToChar() function on the "content" data but I am virtually stuck there.
If anything, I managed to create data frames that contain the codes, which I presume would be used somewhere in the JSON link. Here is what I have.
all.imf.data = fromJSON("http://dataservices.imf.org/REST/SDMX_JSON.svc/Dataflow/")
str(all.imf.data)
#all.imf.data$Structure$Dataflows$Dataflow$Name[[2]] #for the catalogue of sources
catalogue1 = cbind(all.imf.data$Structure$Dataflows$Dataflow$KeyFamilyRef,
all.imf.data$Structure$Dataflows$Dataflow$Name[[2]])
catalogue1 = catalogue1[,-2] # catalogue of all the countries
data.structure = fromJSON("http://dataservices.imf.org/REST/SDMX_JSON.svc/DataStructure/IFS")
info1 = data.frame(data.structure$Structure$Concepts$ConceptScheme$Concept[,c(1,4)])
View(data.structure$Structure$CodeLists$CodeList$Description)
str(data.structure$Structure$CodeLists$CodeList$Code)
#Units
units = data.structure$Structure$CodeLists$CodeList$Code[[1]]
#Countries
countries = data.frame(data.structure$Structure$CodeLists$CodeList$Code[[3]])
countries = countries[,-length(countries)]
#Series Codes
codes = data.frame(data.structure$Structure$CodeLists$CodeList$Code[[4]])
codes = codes[,-length(codes)]
# all.imf.data # JSON from the starting point, provided on the website
# catalogue1 # data frame of all the data bases, International Financial Statistics, Government Financial Statistics, etc.
# codes # codes for the specific data sets (GDP, Current Account, etc).
# countries # data frame of all the countries and their ISO codes
# data.structure # large list, with starting URL and endpoint "IFS". Ideally, I want to find some data set somewhere within this data base.
"info1" # looks like parameters for retrieving the data (for instance, dates, units, etc).
# units # data frame that indicates the options for units
I would just like some advice about how to go about retrieving any data, something as simple as GDP (PPP) for a constant year. I have been following an article in R blogs (which retrieved data in the EU's database) but I cannot replicate the procedure for the IMF. I feel like I am close to retrieving something useful but I cannot quite get there. Given that I have data frames that contain the names for the databases, the series and the codes for the series, I think it is just a matter of figuring out how to construct the appropriate URL for getting the data, but I could be wrong.
Provided in the data frame codes are the codes for the data sets I presume. Is there a way to make a call for the data for, let's say, the US for BK_DB_BP6_USD, which is "Balance of Payments, Capital Account, Total, Debit, etc"? How should I go about doing this in the context of R?
I have a CI and jQuery based project. I've got a site searching my db. It consists of a jQueryUI accordion. One section contains input fields for an advanced search and the other section is used to display a html table with results.
The search parameters from the first section are sent to the server using ajax post. This is crunched by the server and either a html styled error message or a html table with results (and later some other stuff such as how many results found, how much time consumed etc.) is returned.
Back on the client jQuery must be able to distinguish between the two. Best would be to be able to transmit another variable 'search_success'. If 'search_success' is false, the error is prepended to section one above the input fields. Otherwise the html block is displayed in section two and jQuery opens section 2.
Right now I'm returning plain html with a 0 or 1 prepended. This first char is chopped off by jQuery and used to distinguish between the two possible results. This is kind of ugly.
After reading this post about sending array using json I thought about addressing this problem in json.
I intended to build something like
echo json_encode(array('search_success' => $search_success, 'html' => $html));
This would alow for nice structuring of the data. Problem now is, my 'html' is not a simple php variable but a view:
<?php
$template = array('table_open' => '<table id="table" data-url="'.base_url().'">');
$this->table->set_template($template);
$this->table->set_heading($table_header);
echo $this->table->generate($table);
?>
This view could also get a lot more complicated. Of course I could abandon the CI MVC and store the whole html in a php string which I could transform to json with the above code. However, this would defeat the purpose of storing the whole html part in a view.
Is there a way to wrap my whole view in json without relinquishing my view architecture?
Or what approach would be more suitable to the problem?
Thanks, singultus
To bring this topic to an end, the answer is simple:
$json['html'] = $this->load->view('myfile', '', true); // 3. param 'true'!
$json['other_stuff'] = $other stuff;
echo json_encode($json);
See here at the very end. This approach allows for a nicely structured response to the server.

I want to be able to parse specific content from a website into a mySQL database. For example, on site http://allrecipes.com/Recipe/Fluffy-Pancakes-2/Detail.aspx I want to parse into my database (which has a table with columns RecipeName, Ingredients 1-10).
So basically my database will contain the name and all the ingredients for that recipe. There is no need to edit the content, simply parse them in as is (i.e. 3/4 cup milk) since i am using character in my database.
How exactly do I go about doing this? I was looking a pre-built parsers and it seems its tough to find one that's easy to use since I am fairly new to programming. Of course, I can manually enter values in but I want to parse them in.
Would it be possible to just parse this content and write a file that has a RecipieName, Ingredient string which I can then parse into my database? Or should I just do it directly into the database? I am unsure as to how to connect a database to a parser also directly, but I might be able to find some information online.
Basically, I am looking for help on how to exactly go about doing this since I am not very well versed in programming and this seems to be a lot more complicated than it might be.
I am using Java as my main language right now, although I can't say I am very good at it. But I should be able to understand the basic concepts.
Any suggestions on what parser to use or how to do this?
Thanks!
This is how I would do it in PHP. This is almost certainly NOT the most efficient way to do it, nor has it been debugged.
function parseHTML($rawHTML){
$startPosition = strpos($rawHTML,'<div class="ingredients"'); //Find the position of the beginning of the ingredients list, return the character number.
$endPosition = strpos($rawHTML,'</div>',$startPosition); //Find the position of the end of the ingredients list, begin searching from the beginning of the list (found in step 1)
$relevantPart = substr($rawHTML,$startPosition,$endPosition); //Isolate the ingredients list
$parsedString = strip_tags($relevantPart); //Strip the HTML tags off of the ingredients list
return $parsedString;
}
Still to be done: You say you have a mySQL database with 10 separate ingredients columns. This code outputs everything as one big string. You would have to change the strip_tags($relevantPart) function to strip_tags($relevantPart,"<li>"). That would let the <li> tags through. Then, you would have to loop through every <li> tag, performing a similar function to this. It shouldn't be too hard, but I don't feel comfortable writing it with no functioning PHP server.
