laravel 5.3 querybuilder db insère en utilisant l'itération du tableau comme colonne - php, tableaux, laravel-5.3

Je suis nouveau à Laravel et je suis au mieux un amateur avec PHP, mais j'essaie d'apprendre. C’est ma première question, car j’ai généralement réussi à trouver une réponse à ma question.

C’est probablement quelque chose de simple que je «néglige». Je soumets un formulaire pouvant contenir jusqu’à 2 lignes d’une vue à un contrôleur. Je crée un tableau à partir des données, comme dans mon contrôleur:

    foreach($candidates_member_id as $key => $value)
{
$arrData[] = array(
"member_user_id"        => $member_user_id[$key],
"candidates_member_id"  => $candidates_member_id[$key],
"candidates_district"   => $candidates_district[$key],
"candidate_name"        => $candidate_name[$key],
"created_at"            => $created_at[$key],
"updated_at"            => $updated_at[$key]
);
}

Si je print_r ($ arrData) sur la vue associée, j'obtiens les résultats suivants:

Array
(
[0] => Array
(
[member_user_id] => 1
[candidates_member_id] => 12345
[candidates_district] => 6
[candidate_name] => Doe, John
[created_at] => 2016-09-03 15:07:14
[updated_at] => 2016-09-03 15:07:14
)

[1] => Array
(
[member_user_id] => 1
[candidates_member_id] => 54321
[candidates_district] => 6
[candidate_name] => Doe, Jane
[created_at] => 2016-09-03 15:07:15
[updated_at] => 2016-09-03 15:07:15
)
)

Cependant, lorsque j'ajoute DB, insérez-le dans la boucle foreach ci-dessus:

DB::table("primary_votes")->insert(
["member_user_id" => $member_user_id,
"candidates_member_id" => $candidates_member_id,
"candidates_district" => $candidates_district,
"created_at" => $created_at,
"updated_at" => $updated_at]
);

Je reçois l'erreur suivante:

SQLSTATE [42S22]: Colonne introuvable: 1054 Colonne inconnue "0" dans "liste de champs" (SQL: insérer dans primary_votes (0, 1) valeurs (1, 1), (12345, 54321), (6, 6), (2016-09-03 15:07:14, 2016-09-03 15:07:15), (2016-09-03 15:07:14, 2016-09-03 15:07:15)) dans la ligne Connection.php 761 at Connection-> runQueryCallback ("insérer dans primary_votes (0, 1) valeurs (?, ?), (?, ?), (?, ?), (?, ?), (?, ?)

Donc, pour une raison quelconque, je ne peux pas comprendre, il essaie d’utiliser la clé "row" du tableau comme nom de colonne. Pourquoi interprète-t-elle la clé de ligne individuelle comme une colonne dans la base de données? Merci d’avance.

Réponses:

Votre code devrait ressembler à:

foreach($candidates_member_id as $key => $value)
{
$arrData = array(
"member_user_id"        => $member_user_id[$key],
"candidates_member_id"  => $candidates_member_id[$key],
"candidates_district"   => $candidates_district[$key],
"candidate_name"        => $candidate_name[$key],
"created_at"            => $created_at[$key],
"updated_at"            => $updated_at[$key]
);
DB::table("primary_votes")->insert($arrData);
}

La raison de l'erreur mysql est que $ member_user_id, $ candidats_member_id sont des tableaux et non des valeurs scalaires. Vous ne pouvez pas insérer de tableau dans mysql.
