Smarty 检查数组中的项目是否超过 1

Question

我使用 smarty 来显示不同的代码，我想检查一些短语的数组是否包含超过 1 个项目。

我想创建一个 if 短语，用于检查数组是否只包含 1 个或多个值。像这样，但当然是正确的。

{if $domains|@array < 1}

我怎样才能做到这一点？

代码如下所示：

$domains

Smarty_Variable Object (3)
->value = Array (3)
  0 => Array (17)
    domain => "example1.com"
    regperiod => "1"
    dnsmanagement => "on"
    emailforwarding => ""
    idprotection => ""
    addonsCount => 1
    eppvalue => ""
    fields => Array (0)
    configtoshow => true
    hosting => false
  1 => Array (17)
    domain => "example2.com"
    regperiod => "1"
    dnsmanagement => "on"
    emailforwarding => ""
    idprotection => ""
    addonsCount => 1
    eppvalue => ""
    fields => Array (0)
    configtoshow => true
    hosting => false
  2 => Array (17)
    domain => "example3.com"
    regperiod => "1"
    dnsmanagement => "on"
    emailforwarding => ""
    idprotection => ""
    addonsCount => 1
    eppvalue => ""
    fields => Array (0)
    configtoshow => true
    hosting => false
->nocache = false

您可以使用计数（来自 php 函数 http://php.net/manual/es/function.count.php）：

{if $domains|@count < 1}
