export_patterns:csv_export

Due to run-time restrictions, an export must be sequentially callable.
For this purpose, a start URL must be provided. The next URL to be called is indicated by Location-Header (HTTP location).1)
This redirection is followed until a Location-Header is no longer returned.


Parameters

For the incremental export, certain parameters of the Export-URL are supplied.

  • start
    • Determines the first item (offset) to be exported.
  • limit
    • Determines the interval size / number of items to be exported.
  • shopkey
    • Determines the corresponding FINDOLOGIC service for the items to be exported.
    • A separate FINDOLOGIC service is required for each language and subshop.
  • language
    • Determines the language of the items to be exported.

Response

Possible outputs in the body of the script may include:


While the export is still running

SUCCESS: Unfinished: The export is not complete yet; forwarding will occur to the next call.


When the export is completed

SUCCESS: Finished: The export has been correctly completed.

FILE: <PATH_OF_THE_CSV>/<NAME_OF_THE_CSV_FILE>: Output of the path and file name (without domain).


In the case of an error during the export

ERROR, <error message>: An error has been found.


CSV file

The item data is being exported to a CSV file according to a corresponding format
The file name has to be put out after the export (see example below).


Directory

The CSV file has to be created in the usual directory for exports, that is defined in the shop system or (if not available) in the export path, which is set in the shop-backend.


Name

The name of the CSV has to be comprised as follows:

findologic_<shopid>_<language code>.csv

If there is no subshop function in the shop system, i.e. if only a main shop is being used, the default value for the shopid is 0.


Examples

The main shop is being exported in german language:

http://www.mein-shop.de/export/findologic_0_de.csv

A subshop with ID 2 is being exported in English:

http://www.mein-shop.de/export/findologic_2_en.csv

Process


  1. Start
    • The export URL is called by FINDOLOGIC with the parameters described above.
      • Call: http://www.example.com/findologic_export.php?start=0&limit=100&language=de&shopkey=ABCDABCDABCDABCDABCDABCDABCDABCD
  2. Initialisation
    • The CSV file is emptied or created again with the corresponding file names.
  3. Export
    • The number of items to be exported corresponds to the value of the limit parameter.
    • The index of the first item to be exported corresponds to the value of the start parameter (0-based).
    • The items are exported to the CSV-file.
  4. Response
    • A forward to the next item interval is returned.
    • HTTP/1.1 302 Found
      Location: http://www.mein-shop.de/findologic_export.php?start=100&limit=100&language=de&shopkey=ABCDABCDABCDABCDABCDABCDABCDABCD
      ...
      
      SUCCESS: Unfinished
    • The value of the start parameter is the respective value of the last start parameter plus the value of the limit parameter.
    • The value of the limit parameter remains the same.
  5. Repetition from Item 3
  6. Completion
    • If the last item has been exported, the relevant status message is put out:
    • HTTP/1.1 200 OK
      ...
      
      SUCCESS: Finished
      FILE: <PFAD_ZUR_CSV>/<CSV_DATEINAME>
  7. Download
    • The CSV just created is imported by FINDOLOGIC.
    • The product indexing is started by FINDOLOGIC.

Example


  1. Start: http://www.example.com/findologic_export.php?start=0&limit=1000&language=de&shopkey=ABCDABCDABCDABCDABCDABCDABCDABCD
  2. Response:
    HTTP/1.1 302 Found
    Location: http://www.example.com/findologic_export.php?start=1000&limit=1000&language=de&shopkey=ABCDABCDABCDABCDABCDABCDABCDABCD
    ...
    
    SUCCESS: Unfinished
  3. Call: http://www.example.com/findologic_export.php?start=1000&limit=1000&language=de&shopkey=ABCDABCDABCDABCDABCDABCDABCDABCD
  4. Response:
    HTTP/1.1 200 OK
    ...
    
    SUCCESS: Finished
    FILE: findologic_1_de.csv
  5. Export successfully completed, CSV download

Other


.htaccess protection

The export script can also be in a .htaccess-protected area. For this purpose, you can store a user name and password in the FINDOLOGIC customer account under Settings → Import/Export → Export Settings.


Load-Balancing

If you use load-balancing in your infrastructure, please ensure, that export calls are always forwarded to the same host or to a host that is outside the cluster. Otherwise the export cannot be completely generated.


1)
This start URL can be entered in the FINDOLOGIC customer account in the export URL field under “Settings” –> “Import/Export” –> “Export”.
