Question

在我的小WP项目中，我有一个表单（wp作业管理器）中的标题字段，我需要被禁用但我也想自动插入一个数字，所以当表单被POST时，数字将是保存为标题名称。我想用占位符做某种方式，但我找不到方法。

'job_title' => array(
    'label'       => __( 'Job Title', 'wp-job-manager' ),
    'type'        => 'text',
    'required'    => false,
    'placeholder' => '',
    'priority'    => 1
),

或者第二个选项，如果有任何脚本可以自动分配POST ID或数字来清空标题？

非常感谢，如果有人可以提供帮助的话。我工作了几个小时，找不到工作的解决方案，因为我是一个php初学者。

使用表单的In file included from /Volumes/second/nvi/github/blockchain_db/src/Impl/mongo/src/mongo_db_api.cpp:3: /Volumes/second/nvi/github/blockchain_db/src/Impl/mongo/src/mongo_db_api_utils.hpp:47:46: error: no viable conversion from 'typename std::enable_if<!util::is_functor<const finalize_type &, void (single_context)>::value, key_context<closed_context> >::type' (aka 'bsoncxx::v_noabi::builder::stream::key_context<bsoncxx::v_noabi::builder::stream::closed_context>') to 'bsoncxx::document::view_or_value' (aka 'view_or_value<document::view, document::value>') auto cursor = db["ctlblocks"].find_one(document{} << filter << finalize); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /usr/local/include/bsoncxx/v_noabi/bsoncxx/view_or_value.hpp:60:20: note: candidate constructor not viable: no known conversion from 'typename std::enable_if<!util::is_functor<const finalize_type &, void (single_context)>::value, key_context<closed_context> >::type' (aka 'bsoncxx::v_noabi::builder::stream::key_context<bsoncxx::v_noabi::builder::stream::closed_context>') to 'bsoncxx::v_noabi::document::view' for 1st argument BSONCXX_INLINE view_or_value(View view) : _view{view} { ^ /usr/local/include/bsoncxx/v_noabi/bsoncxx/view_or_value.hpp:69:20: note: candidate constructor not viable: no known conversion from 'typename std::enable_if<!util::is_functor<const finalize_type &, void (single_context)>::value, key_context<closed_context> >::type' (aka 'bsoncxx::v_noabi::builder::stream::key_context<bsoncxx::v_noabi::builder::stream::closed_context>') to 'bsoncxx::v_noabi::document::value &&' for 1st argument BSONCXX_INLINE view_or_value(Value&& value) : _value(std::move(value)), _view(*_value) { ^ /usr/local/include/bsoncxx/v_noabi/bsoncxx/view_or_value.hpp:75:20: note: candidate constructor not viable: no known conversion from 'typename std::enable_if<!util::is_functor<const finalize_type &, void (single_context)>::value, key_context<closed_context> >::type' (aka 'bsoncxx::v_noabi::builder::stream::key_context<bsoncxx::v_noabi::builder::stream::closed_context>') to 'const bsoncxx::v_noabi::view_or_value<bsoncxx::v_noabi::document::view, bsoncxx::v_noabi::document::value> &' for 1st argument BSONCXX_INLINE view_or_value(const view_or_value& other) ^ /usr/local/include/bsoncxx/v_noabi/bsoncxx/view_or_value.hpp:93:20: note: candidate constructor not viable: no known conversion from 'typename std::enable_if<!util::is_functor<const finalize_type &, void (single_context)>::value, key_context<closed_context> >::type' (aka 'bsoncxx::v_noabi::builder::stream::key_context<bsoncxx::v_noabi::builder::stream::closed_context>') to 'bsoncxx::v_noabi::view_or_value<bsoncxx::v_noabi::document::view, bsoncxx::v_noabi::document::value> &&' for 1st argument BSONCXX_INLINE view_or_value(view_or_value&& other) noexcept属性分配号码。您可以在onsubmit属性中添加javascript函数/代码。
