Php 如何添加数组以查找字段

我只想检索Person.id、Person.displayName和Obk.0.id。前两个是没有问题的,但是当我尝试获取Obk.0.id时,我会得到错误:SQLSTATE[42P01]:未定义的表:7错误:缺少表Obk的
我怎么能得到那样的东西?我想稍后在codion中设置该值,但它会阻止我的工作。在CakePHP 2中,您可以使用
字段选项指定要通过find()
查询返回的字段,如:-
$this->Foo->find('all', [
'fields' => ['Foo.id', 'Foo.name']
]);
这也适用于具有belongsTo
或hasOne
关系的包含模型:-
$this->Foo->find('all', [
'fields' => ['Foo.id', 'Foo.name', 'Bar.name'],
'contain' => ['Bar']
]);
但是,如果包含的模型是hasMany
或HABTM关系,则需要在包含上指定该模型的字段:-
$this->Foo->find('all', [
'fields' => ['Foo.id', 'Foo.name'],
'contain' => [
'Bar' => ['fields' => 'Bar.name']
]
]);
这是因为CakePHP将执行多个SQL查询,因此contain需要为相关模型运行查询的参数。那么您的实际问题是什么?我想你需要说得更清楚一点。你的查找功能如何?你到底需要什么样的结果?在cakephp中使用debug而不是print_r。
