如何在zend字面内逃避事物？

Question

我正在创建一个高级搜索,并想通过将它们添加到一个数组来循环我的查询:

private $searchFields = [
    'as_first_name'                  => 'users.first_name like "%VALUE%"',
    'as_last_name'                   => 'users.last_name like "%VALUE%"',
    'as_payment_history_invoice_num' => 'users.user_id = (SELECT user_id from payment_history where payment_history.invoice_number = "VALUE" LIMIT 1)',
    'as_building_num'                => 'property_units.building_number like "%VALUE%"',
    'as_residents_email'             => 'users.email like "%VALUE%"',
    'as_property_name'               => 'property.name like "%VALUE%"',
    'as_phone_num'                   => 'REPLACE(REPLACE(REPLACE(REPLACE(users.phone, " ", ""), "(", ""), ")", ""), "-", "") = "VALUE"',
    'as_unit_num'                    => 'property_units.unit_number = "VALUE"',
    'as_account_status'              => 'user_status.status_name = "VALUE"'
];

所以在搜索我做的事情...

if (array_key_exists($key, $this->searchFields)) {

    $form->get($key)->setValue($val);
    $where->NEST->literal(str_replace('VALUE', urldecode($val), $this->searchFields[$key]))->UNNEST;
}

但问题是我没有逃避任何事情.不好.我怎样才能使用相同的结构,但也可以逃避.

Literal谓词是针对没有占位符的情况.你应该使用Expression谓词.

private $searchFields = [
    'as_first_name'                  => 'users.first_name like "?"',
    'as_last_name'                   => 'users.last_name like "?"',
    'as_payment_history_invoice_num' => 'users.user_id = (SELECT user_id from payment_history where payment_history.invoice_number = "?" LIMIT 1)',
    'as_building_num'                => 'property_units.building_number like "?"',
    'as_residents_email'             => 'users.email like "?"',
    'as_property_name'               => 'property.name like "?"',
    'as_phone_num'                   => 'REPLACE(REPLACE(REPLACE(REPLACE(users.phone, " ", ""), "(", ""), ")", ""), "-", "") = "?"',
    'as_unit_num'                    => 'property_units.unit_number = "?"',
    'as_account_status'              => 'user_status.status_name = "?"'
];

zend-form值应该已经被解码,因此不需要urldecode

if (array_key_exists($key, $this->searchFields)) {

    $form->get($key)->setValue($val);
    $where->NEST->expression($this->searchFields[$key], $val)->UNNEST;
}

我很长一段时间没有使用zend-db,请确保检查此代码实际上是否产生了您需要的查询.
