在destoon中模块的自定义字段存储在destonn_fields这个表中
自定义字段的前台显示使用的是fields_html这个函数在fields.func.php文件中，这个函数的定义如下，
[code]function fields_html($left = ‘<td class=”tl”>’, $right = ‘<td>’, $values = array(), $fd = array()) {
extract($GLOBALS, EXTR_SKIP);
if($fd) $FD = $fd;
$html = ”;
foreach($FD as $k=>$v) {
if(!$v[‘display’]) continue;
if(!defined(‘DT_ADMIN’) && !$v[‘front’]) continue;
$html .= fields_show($k, $left, $right, $values, $fd);
}
return $html;
} [/code]
这个函数不是使用$left与right这两个变量中包含的html包住我们自定义的字段，这样就显示非常的不和谐，很不好自定义界面，
这个函数中使用的了一个$FD的变量，这个变量是一个全局变量，在用户中心显示编辑界面时，变量的初始公是在my.inc.php中
[code]if (in_array($action, array(‘add’, ‘edit’)))
{
$FD = cache_read(‘fields-‘ . substr($table, strlen($DT_PRE)) . ‘.php’);
if ($FD) require DT_ROOT . ‘/include/fields.func.php’;
isset($post_fields) or $post_fields = array();
$CP = $MOD[‘cat_property’];
if ($CP) require DT_ROOT . ‘/include/property.func.php’;
isset($post_ppt) or $post_ppt = array();
}[/code]
$FD是从缓存中读取的，其中的形式如下，
[code]<?php defined(‘IN_DESTOON’) or exit(‘Access Denied’);
return array(
19 => array(‘itemid’ => ’19’, ‘tb’ => ‘dingzhi_40’, ‘name’ => ‘qidian’, ‘title’ => ‘起点’, ‘note’ => ”, ‘type’ => ‘int’, ‘length’ => ’10’, ‘html’ => ‘area’, ‘default_value’ => ”, ‘option_value’ => ”, ‘width’ => ‘120’, ‘height’ => ’90’, ‘input_limit’ => ”, ‘addition’ => ”, ‘display’ => ‘1’, ‘front’ => ‘1’, ‘listorder’ => ‘0’,),
20 => array(‘itemid’ => ’20’, ‘tb’ => ‘dingzhi_40’, ‘name’ => ‘zhongdian’, ‘title’ => ‘终点’, ‘note’ => ”, ‘type’ => ‘int’, ‘length’ => ’10’, ‘html’ => ‘area’, ‘default_value’ => ”, ‘option_value’ => ”, ‘width’ => ‘120’, ‘height’ => ’90’, ‘input_limit’ => ”, ‘addition’ => ”, ‘display’ => ‘1’, ‘front’ => ‘1’, ‘listorder’ => ‘0’,),
21 => array(‘itemid’ => ’21’, ‘tb’ => ‘dingzhi_40’, ‘name’ => ‘shuojihao’, ‘title’ => ‘手机号’, ‘note’ => ”, ‘type’ => ‘varchar’, ‘length’ => ’15’, ‘html’ => ‘text’, ‘default_value’ => ”, ‘option_value’ => ”, ‘width’ => ‘120’, ‘height’ => ’90’, ‘input_limit’ => ”, ‘addition’ => ‘size=”30″‘, ‘display’ => ‘1’, ‘front’ => ‘1’, ‘listorder’ => ‘0’,),
22 => array(‘itemid’ => ’22’, ‘tb’ => ‘dingzhi_40’, ‘name’ => ‘shixiao’, ‘title’ => ‘时效’, ‘note’ => ”, ‘type’ => ‘varchar’, ‘length’ => ‘255’, ‘html’ => ‘radio’, ‘default_value’ => ”, ‘option_value’ => ‘1|1天内*2|2天内*3|3天内*4|4天内*5|5天内*6|6天内*7|7天内*’, ‘width’ => ‘120’, ‘height’ => ’90’, ‘input_limit’ => ”, ‘addition’ => ”, ‘display’ => ‘1’, ‘front’ => ‘1’, ‘listorder’ => ‘0’,),);
?>[/code]
如果我们需要对字段的显示名称进行更改，那么就需要传入整个array才能达到目的，个人觉得有点麻烦了
个人觉得如果要修改某个字段的相关特性时，只需要传入特定属性就可以了，因此我对函数做了一点改变，因为我只需要改变title就可以，所以没有对这个函数做太大的改动
{php $mycust=array(“qidian”=>”发车起点：”);}
{if $FD}{fields_html3(‘<li><p>–name–：</p><span>–control–</span></li>’,$item, $mycust)}{/if}
[code]function fields_html3($template, $values = array(), $mycust = array()) {
extract($GLOBALS, EXTR_SKIP);
// if($fd) $FD = $fd;这里的本意是用我们自定义的字段来替换从缓存中读取的字段，但是这样的就有点麻烦，
// print_r($FD);
$html = ”;
foreach ($FD as $k => &$v)
{
if (!$v[‘display’]) continue;
if (!defined(‘DT_ADMIN’) && !$v[‘front’]) continue;
$v[“temphtml”] = fields_show2($k, $values );
$title = $v[“title”];
if(isset($mycust[$v[“name”]])) $title = $mycust[$v[‘name’]];
$temp = str_replace(“–name–“, $title,$template);
$temp = str_replace(“–control–“, $v[“temphtml”],$temp);
$html.=$temp.”\r\n”;
}
return $html;
} [/code]
