How to update mysql table with array of data - Laravel - laravel

Question

I am trying to update multiple rows using this code:
$data = [];
foreach ($projectFieldOptions as $mapping) {
$data[] = [
'import_field_slug' => $mapping['value'],
'internal_field_slug' => $mapping['text'],
'custom_field' => $mapping['custom'],
'import' => 1,
'date_upd' => $now,
];
}
$update_feed_mappings = DB::table($db_name . '.feed_mappings')
->where('id_project', $token)
->where('id_feed', $id_feed)
->update($data);
But I got this error:
SQLSTATE[42S22]: Column not found: 1054 Unknown column '0' in 'field list' (SQL: update `shibbir_DB1`.`feed_mappings` set `0` = {\"import_field_slug\":\"date\",..........
Would you tell me how can I fix it?

Answer 1

update only works for a single row and each key must correspond to a column in your sql table. You can't use if with a multi-dimensional array.
You should move your update inside your loop to fix the issue.
foreach ($projectFieldOptions as $mapping) {
$data = [
'import_field_slug' => $mapping['value'],
'internal_field_slug' => $mapping['text'],
'custom_field' => $mapping['custom'],
'import' => 1,
'date_upd' => $now,
];
DB::table($db_name . '.feed_mappings')
->where('id_project', $token)
->where('id_feed', $id_feed)
->update($data);
}

Consider the code below please
$data = [];
$projectFieldOptions =
$data[] = [
'import_field_slug' => 1,
'internal_field_slug' => 1,
'custom_field' => 1,
'import' => 1,
'date_upd' => 1,
];
$data[] = [
'import_field_slug' => 2,
'internal_field_slug' => 2,
'custom_field' => 2,
'import' => 2,
'date_upd' => 2,
];
var_dump($data);
The output will be
array(2) {
[0]=>
array(5) {
["import_field_slug"]=>
int(1)
["internal_field_slug"]=>
int(1)
["custom_field"]=>
int(1)
["import"]=>
int(1)
["date_upd"]=>
int(1)
}
[1]=>
array(5) {
["import_field_slug"]=>
int(2)
["internal_field_slug"]=>
int(2)
["custom_field"]=>
int(2)
["import"]=>
int(2)
["date_upd"]=>
int(2)
}
}
So your update translates into something like that
update(['0' => array(...))
But update method needs something like that
update(['import_field_slug' => 1,...])
Conclusion: please update each record one by one inside your loop
