//自定义函数调用数据表
function table($table, $field, $id)
{
global $dsql;
$primarys = array();
$table = strpos($table,'#@_') ===false?(strpos($table,'dede_') ===false?'dede_'.$table:str_replace('dede_','dede_',$table)):$table;
$dsql -> Execute("me","SHOW COLUMNS FROM `$table`");
while($r = $dsql->GetArray())
{
if($r['Key'] =='PRI') $primarys[] = $r['Field'];
}
if(!empty($primarys))
{
$primary = $primarys[0];
$result = $dsql -> GetOne("SELECT `$field` FROM `$table` WHERE `$primary`= $id");
}
returnisset($result[$field])?$result[$field]:$result[$field];
}

然后在我们需要调用数据的地方加上调用代码：
