Add 1 second in between array items so that created_at in db aren't all the same, Laravel creat-CodePudding

I have a table called event_speakers. In the app, a user can click on a icon and add as many speakers as they want.

I'm using a for loop and then Laravel's createMany method. The problem is that the order of the speakers is coming out wrong when I fetch them from the db, and I can't sort them because the created_at and updated_at columns in the database are all exactly the same.

Is there a way to somehow add a second or a few milliseconds in between each record so that the created_at date and time are not all exactly the same?

Here is my code that successfully inserts the data:

for ($i = 0; $i < $numRecords; $i  ) {
    if ($request->speaker_name_en[$i] != null) {
        $data[] = [
            'photo' => $this->uploadImage($livestream, $client, $request['speaker_image_en'][$i]),
            'name_en' => $request->speaker_name_en[$i],
            'name_fr' => $request->speaker_name_fr[$i],
            'title_en' => $request->speaker_title_en[$i],
            'subtitle_en' => $request->speaker_subtitle_en[$i],
            'description_en' => $request->speaker_description_en[$i],
            'title_fr' => $request->speaker_title_fr[$i],
            'subtitle_fr' => $request->speaker_subtitle_fr[$i],
            'description_fr' => $request->speaker_description_fr[$i],
            'client_id' => $client->id
        ];
    }
}
if (isset($data)) {
    $client->eventspeakers()->createMany($data);
}

Any ideas?

Why not orderBy() a different column? https://laravel.com/docs/9.x/queries#ordering-grouping-limit-and-offset

You could also specify the created_at and add a second each iteration

for ($i = 0; $i < $numRecords; $i  ) {
    if ($request->speaker_name_en[$i] != null) {
        $data[] = [
            'photo' => $this->uploadImage($livestream, $client, $request['speaker_image_en'][$i]),
            'name_en' => $request->speaker_name_en[$i],
            'name_fr' => $request->speaker_name_fr[$i],
            'title_en' => $request->speaker_title_en[$i],
            'subtitle_en' => $request->speaker_subtitle_en[$i],
            'description_en' => $request->speaker_description_en[$i],
            'title_fr' => $request->speaker_title_fr[$i],
            'subtitle_fr' => $request->speaker_subtitle_fr[$i],
            'description_fr' => $request->speaker_description_fr[$i],
            'client_id' => $client->id,
            'created_at' => now()->addSeconds($i),
        ];
    }
}
if (isset($data)) {
    $client->eventspeakers()->createMany($data);
}

When you fetch your speakers data, you can sort them directly by ID instead of created_at
