我知道有几个类似的帖子，但他们没有给我我需要的答案。所以，我正在使用 Phinx 并尝试添加外键，但出现以下错误：

General error: 1215 Cannot add foreign key constraint

这是带有外键的 php 文件：

<?php

use Phinx\Migration\AbstractMigration;

class CustomQuotes extends AbstractMigration
{
    /**
     * Change Method.
     *
     * Write your reversible migrations using this method.
     *
     * More information on writing migrations is available here:
     * http://docs.phinx.org/en/latest/migrations.html#the-abstractmigration-class
     *
     * The following commands can be used in this method and Phinx will
     * automatically reverse them when rolling back:
     *
     *    createTable
     *    renameTable
     *    addColumn
     *    renameColumn
     *    addIndex
     *    addForeignKey
     *
     * Remember to call "create()" or "update()" and NOT "save()" when working
     * with the Table class.
     */
    public function change()
    {
        $table = $this->table('custom_quotes', ['id' => false, 'primary_key' => ['custom_quote_id']]);
        $table->addColumn('custom_quote_id', 'biginteger', ['identity' =>true, 'signed' => false])
        ->addColumn('account_id', 'biginteger', ['limit' => 20, 'null' => true])
        ->addColumn('quote_type_id', 'integer', ['limit' => 11, 'null' => true])
        ->addColumn('quote', 'string', ['limit' => 500, 'null' => true])
        ->addColumn('selected', 'integer', ['limit' => 4, 'null' => true, 'default' => 1])
        ->addForeignKey('account_id', 'accounts', 'account_id', array('delete'=> 'NO_ACTION', 'update'=> 'NO_ACTION'))
        ->addForeignKey('quote_type_id', 'quote_types', 'quote_type_id', array('delete'=> 'NO_ACTION', 'update'=> 'NO_ACTION'))
        ->create();
    }
}

我试图从中获取 id 的两个表是在上表之前创建的。这是另外两个表：

报价类型表 

use Phinx\Migration\AbstractMigration;

class CustomQuotes extends AbstractMigration

     */
    public function change()
    {
        $table = $this->table('custom_quotes', ['id' => false, 'primary_key' => ['custom_quote_id']]);
        $table->addColumn('custom_quote_id', 'biginteger', ['identity' =>true, 'signed' => false])
        ->addColumn('account_id', 'biginteger', ['limit' => 20, 'null' => true])
        ->addColumn('quote_type_id', 'integer', ['limit' => 11, 'null' => true])
        ->addColumn('quote', 'string', ['limit' => 500, 'null' => true])
        ->addColumn('selected', 'integer', ['limit' => 4, 'null' => true, 'default' => 1])
        ->addForeignKey('account_id', 'accounts', 'account_id', array('delete'=> 'NO_ACTION', 'update'=> 'NO_ACTION'))
        ->addForeignKey('quote_type_id', 'quote_types', 'quote_type_id', array('delete'=> 'NO_ACTION', 'update'=> 'NO_ACTION'))
        ->create();
    }
}

        $table->addColumn('account_id', 'biginteger', ['identity' =>true, 'signed' => false])

所以我想通了。结果我不得不在 custom_quotes 表中使我的 account_id 和 quote_type_id 无符号，因为我在 accounts 和 quote_type 表中使它们无符号。现在说得通了。这是解决方案：

<?php

use Phinx\Migration\AbstractMigration;

class CustomQuotes extends AbstractMigration
{
    /**
     * Change Method.
     *
     * Write your reversible migrations using this method.
     *
     * More information on writing migrations is available here:
     * http://docs.phinx.org/en/latest/migrations.html#the-abstractmigration-class
     *
     * The following commands can be used in this method and Phinx will
     * automatically reverse them when rolling back:
     *
     *    createTable
     *    renameTable
     *    addColumn
     *    renameColumn
     *    addIndex
     *    addForeignKey
     *
     * Remember to call "create()" or "update()" and NOT "save()" when working
     * with the Table class.
     */
    public function change()
    {
        $table = $this->table('custom_quotes', ['id' => false, 'primary_key' => ['custom_quote_id']]);
        $table->addColumn('custom_quote_id', 'biginteger', ['identity' =>true, 'signed' => false])
        ->addColumn('account_id', 'biginteger', ['limit' => 20, 'null' => true, "signed" => false])
        ->addColumn('quote_type_id', 'integer', ['limit' => 11, 'null' => true, "signed" => false])
        ->addColumn('quote', 'string', ['limit' => 500, 'null' => true])
        ->addColumn('selected', 'integer', ['limit' => 4, 'null' => true, 'default' => 1])
        ->addForeignKey('account_id', 'accounts', 'account_id', array('delete'=> 'NO_ACTION', 'update'=> 'NO_ACTION'))
        ->addForeignKey('quote_type_id', 'quote_types', 'quote_type_id', array('delete'=> 'NO_ACTION', 'update'=> 'NO_ACTION'))
        ->create();
    }
}
