Discuz!开发之网站后台表单生成函数showsetting()详情

Discuz!为了界面统一，专门封装了一个表单生成函数showsetting()，使用改函数几乎可以生成任意web表单，本文就来介绍一下这个函数的用法：

定义文件：\source\function\function_admincp.php

函数定义：

function showsetting($setname, $varname, $value, $type = 'radio', $disabled = '', $hidden = 0, $comment = '', $extra = '', $setid = '', $nofaq = false) {global $_G;$s = "\n";$check = array();$noborder = false;if(substr($disabled, 0, 8) == 'noborder') {$disabled = trim(substr($disabled, 8));$noborder = 'class="noborder" ';}$check['disabled'] = $disabled ?

参数说明：

$setname - 指定输出标题，如:setting_basic_bbname, 自动匹配描述文字为：setting_basic_bbname_comment，comment形式文字可以在./source/language/lang_admincp.php语言包中添加

$varname - 指定表单的name值，如settingnew[bbname]

$value - 指定表单默认值\变量

$type - 表单样式

radio单选

text文本、password密码、number数字

file上传文件

filetext 上传文件或在线文件切换型表单

textarea 多行文本

select 选择框

mradio 高级单选模式

mcheckbox 高级多选模式

binmcheckbox 二进制数值多选模式

mselect 高级选择框模式

color 颜色选择

calendar 日期选择

multiply多表单型，daterange时间范围

其他未在上述样式中出现的$type均独立输出

$disabled - 是否不可修改

$hidden - 是否隐藏

$comment - 强制描述文字

$extra - 表单扩展属性

$setid - 用于拼接表单外层Div的id

使用方法举例：

//以文本形式输出表单(站点名称 text)：showsetting('setting_basic_bbname', 'settingnew[bbname]', $setting['bbname'], 'text');//以单选形式输出表单(显示授权信息链接 radio)：showsetting('setting_basic_boardlicensed', 'settingnew[boardlicensed]', $setting['boardlicensed'], 'radio');//以多行文本形式输出表单(网站第三方统计代码 textarea)：showsetting('setting_basic_stat', 'settingnew[statcode]', $setting['statcode'], 'textarea');//以高级单选形式输出表单(新用户注册验证 mradio)showsetting('setting_access_register_verify', array('settingnew[regverify]', array(array(0, $lang['none'], array('regverifyext' => 'none')),array(1, $lang['setting_access_register_verify_email'], array('regverifyext' => '')),array(2, $lang['setting_access_register_verify_manual'], array('regverifyext' => '')))), $setting['regverify'], 'mradio');//以高级多选形式输出表单('允许新用户注册 mcheckbox)showsetting('setting_access_register_status', array('settingnew[regstatus]', array(array('open', $lang['setting_access_register_open']),array('invite', $lang['setting_access_register_invite'], 'showinvite'),$_G['setting']['connect']['allow'] ? array('connect', $lang['setting_access_register_connect'], 'showconnect') : array(),)), $regstatus, 'mcheckbox');
