Python Write Array To Csv File
How using Codeigniter framework save array as file and download it without save on server first? I have two buttons. There is one more function called array_to_csv which put the data stored in the array. Generating CSV file using CodeIgniter Framework.
This isn't a problem as such, more a request for an optimum way of exporting a query from Codeigniter as a downloadable CSV. In CI, I call a simple query (eg select. from members where country=123) from a model in a controller (eg members), along the lines of: $data'membercountriesquery' = $this - Queriesmodel - getmembersbycountry($countryid); This goes off to a view where I display human-readable information on members in a country.
I can easily generate a CSV of this result in the view or controller with $this-dbutil-csvfromresult($membercountriesquery), and display it in the view. I would like to then present the user with a button/hyperlink 'download result as CSV', which will generate a file save dialogue. I've done a fair bit of googling and hunting on SO and there are many possible solutions of varying degrees of complexity. I thought of perhaps adding a controller function, (eg member/createcsv($data)), but couldn't think of a way to pass the CSV $data to it from a page link (that might be another question completely).

Could someone please advise on the simplest and quickest way to create a CSV download link? I'd prefer not, for security reasons, to save the CSV file to server and then create a link to the saved file. It would be especially useful to be able to create a general helper/function which would take any query result and produce downloadable CSV. I am grateful to the CI folk for producing the dbutil and download helpers, and the simplest way of doing this must involve both csvfromresult and forcedownload, but I just can't think at this late hour of a way to combine the two in a view (or whatever):(.

A Comma separated values (CSV) file is a computer data file used for implementing the tried and true organizational tool, the Comma Separated List. The CSV file is used for the digital storage of data structured in a table of lists form, where each associated item (member) in a group is in association with others also separated by the commas of its set. Each line in the CSV file corresponds to a row in the table. Within a line, fields are separated by commas, each field belonging to one table column.
Read more about this file format. There is a handy library available in CodeIgniter framework which is the that will makes reading or parsing CSV formatted data easily. In this article, I try to show you how to use it. But since this library is not included in CodeIgniter package you need to add this to your system/libraries directory. Create a new file in your system/libraries directory named it to csvreader.php. Go and download the code.
