Feeds Documentation for importing data programatically [closed]

Question

Team,

I need a help.

I was surfing internet, but couldn't get a luck to get a working example/documentation to import data programmatically and store into our custom tables.

I'm using Drupal 9 version and feeds module, and for importing data related to users, content type, feeds modules help me a lot. But we have some custom tables as well, and stuck here to import. I have followed below link, but have stuck in coding part to get & store the values in custom table.

https://www.drupal.org/docs/contributed-modules/feeds/creating-a-custom-feeds-workflow

And, everywhere, I'm getting the links for import using front-end, but not via programatically.

https://www.specbee.com/blogs/how-import-external-feeds-your-drupal-9-website-feeds-module

https://metadrop.net/en/articles/import-your-content-feeds-drupal

I have asked some of my known Drupalers, and in my circle, we are not having a handy documentation or code example for importing data and storing in custom table. My friends recommended some other contrib modules for this case, but I would like to know if I can achieve this using Feeds.

I just need to import some data using csv file and store it in custom tables. Please do share if any working code example is there with anybody or any links over internet you have seen which I missed, please do share, kindly help.

Thanks in advance.

I will assume a scenario where you just need to import some simple data from a csv file into Drupal. No multi value fields, no reference fields (including image fields), etc. Such scenario would require a much complicated script.

The solution I’m suggesting (bellow) assumes that you have drush installed and you are willing to run a php script under drush.

Something like the following might work:

<?php

// php -d memory_limit=-1 vendor/bin/drush php:script import_nodes.php

// general options
$csv_file_name = '/the/path/to/file.csv';
$type = 'some_type';

// get csv
$items_to_import = get_array_from_csv ($csv_file_name);

// start import
foreach ($items_to_import as $item) {

        // set title
        $title = $item['title'];

        // create node
        $node = \Drupal::entityTypeManager()
                    ->getStorage('node')
                    ->create([
                        'type' => $type,
                        'title' => $title,
                    ]);

        // set field_foo
        $field_foo = $item['field_foo'];
        $node->set('field_foo', $field_foo);

        // set field_bar
        $field_bar = $item['field_bar'];
        $node->set('field_bar', $field_bar);

        $node->save();
        unset ($node);

}

function get_array_from_csv ($filePath) {

    $dataArray = [];

    $rows = array_map ('str_getcsv', file ($filePath));
    $header = array_shift ($rows);

    foreach($rows as $row) {

        $dataArray[] = array_combine ($header, $row);

    }

    return $dataArray;

}

Run it (from your site directory) with the command:

php vendor/bin/drush php:script import_nodes.php

Or (if on low allocated memory for php) with the command:

php -d memory_limit=-1 vendor/bin/drush php:script import_nodes.php
