dedecms获得首字母的方法,并实现文章列表按首字母归类

整理编辑:www.qitehu.com 更新时间:04-18 阅读:

方法一,织梦默认有这个函数,在include/inc/inc_fun_funAdmin.php中.即SpGetPinyin()

但他只能得到全拼,没法得到首字母,用法举例
$pingyin=GetPinyin($row['title'],0,1);
$a=substr(GetPinyin($row['title']),0,1);//得到拼音首字母 <a class="ViewSource" href="http://blog.csdn.net/viqecel/article/details/50087975#" style="font-family: Verdana, Geneva, Arial, Helvetica, sans-serif; font-size: 9px; box-sizing: border-box; color: rgb(202, 12, 22); text-decoration: none; margin: 0px 10px 0px 0px; padding: 1px; outline: none; border: none; display: inline-block; width: 16px; height: 16px; text-indent: -2000px; background-image: url("images/default/ico_plain.gif"); background-attachment: initial; background-color: inherit; background-size: initial; background-origin: initial; background-clip: initial; background-position: 0% 0%; background-repeat: no-repeat;" title="view plain">view plai</a><span class="tracking-ad" data-mod="popu_168" style="color: silver; font-family: Verdana, Geneva, Arial, Helvetica, sans-serif; font-size: 9px; box-sizing: border-box; margin: 0px; padding: 0px;"> <a class="CopyToClipboard" href="http://blog.csdn.net/viqecel/article/details/50087975#" style="box-sizing: border-box; color: rgb(202, 12, 22); text-decoration: none; margin: 0px 10px 0px 0px; padding: 1px; outline: none; border: none; font-size: 9px; display: inline-block; width: 16px; height: 16px; text-indent: -2000px; background-image: url("images/default/ico_copy.gif"); background-attachment: initial; background-color: inherit; background-size: initial; background-origin: initial; background-clip: initial; background-position: 0% 0%; background-repeat: no-repeat;" title="copy">copy</a></span>
方法二,如果你只想得到首字母,不需要全拼,还可以用以下函数得到首字母
if (ord($row['title'])>128) { //汉字开头
 $letter=getfirstchar2($row['title']);
}else if(ord($row['title'])>=48 and ord($row['title'])<=57){ //数字开头
 $letter=iconv_substr($title,0,1,'utf-8');
}else if(ord($row['title'])>=65 and ord($row['title'])<=90){ //大写英文开头
$letter=iconv_substr($row['title'],0,1,'utf-8');
}else if(ord($row['title'])>=97 and ord($row['title'])<=122){ //小写英文开头
 $letter=iconv_substr($row['title'],0,1,'utf-8');
$letter=strtoupper($letter);//字母转换成大写
}
print_r($letter);exit;
 function getfirstchar2($s0){
$s=iconv("UTF-8","gb2312", $s0); 
$asc=ord($s{0})*256+ord($s{1})-65536; 
if($asc>=-20319 and $asc<=-20284)return "A"; 
if($asc>=-20283 and $asc<=-19776)return "B"; 
if($asc>=-19775 and $asc<=-19219)return "C"; 
if($asc>=-19218 and $asc<=-18711)return "D"; 
if($asc>=-18710 and $asc<=-18527)return "E"; 
if($asc>=-18526 and $asc<=-18240)return "F"; 
if($asc>=-18239 and $asc<=-17923)return "G"; 
if($asc>=-17922 and $asc<=-17418)return "H"; 
if($asc>=-17417 and $asc<=-16475)return "J"; 
if($asc>=-16474 and $asc<=-16213)return "K"; 
if($asc>=-16212 and $asc<=-15641)return "L"; 
if($asc>=-15640 and $asc<=-15166)return "M"; 
if($asc>=-15165 and $asc<=-14923)return "N"; 
if($asc>=-14922 and $asc<=-14915)return "O"; 
if($asc>=-14914 and $asc<=-14631)return "P"; 
if($asc>=-14630 and $asc<=-14150)return "Q"; 
if($asc>=-14149 and $asc<=-14091)return "R"; 
if($asc>=-14090 and $asc<=-13319)return "S"; 
if($asc>=-13318 and $asc<=-12839)return "T"; 
if($asc>=-12838 and $asc<=-12557)return "W"; 
if($asc>=-12556 and $asc<=-11848)return "X"; 
if($asc>=-11847 and $asc<=-11056)return "Y"; 
if($asc>=-11055 and $asc<=-10247)return "Z"; 
return false; 
}<a class="ViewSource" href="http://blog.csdn.net/viqecel/article/details/50087975#" se_prerender_url="complete" style="font-family: Verdana, Geneva, Arial, Helvetica, sans-serif; font-size: 9px; box-sizing: border-box; color: rgb(202, 12, 22); text-decoration: none; margin: 0px 10px 0px 0px; padding: 1px; outline: none; border: none; display: inline-block; width: 16px; height: 16px; text-indent: -2000px; background-image: url("images/default/ico_plain.gif"); background-attachment: initial; background-color: inherit; background-size: initial; background-origin: initial; background-clip: initial; background-position: 0% 0%; background-repeat: no-repeat;" title="view plain">view plain</a><span class="tracking-ad" data-mod="popu_168" style="color: silver; font-family: Verdana, Geneva, Arial, Helvetica, sans-serif; font-size: 9px; box-sizing: border-box; margin: 0px; padding: 0px;"> <a class="CopyToClipboard" href="http://blog.csdn.net/viqecel/article/details/50087975#" style="box-sizing: border-box; color: rgb(202, 12, 22); text-decoration: none; margin: 0px 10px 0px 0px; padding: 1px; outline: none; border: none; font-size: 9px; display: inline-block; width: 16px; height: 16px; text-indent: -2000px; background-image: url("images/default/ico_copy.gif"); background-attachment: initial; background-color: inherit; background-size: initial; background-origin: initial; background-clip: initial; background-position: 0% 0%; background-repeat: no-repeat;" title="copy">cop</a></span>

三,如何实现文章列表中,按首字母进行归类归档排序?下面是完整代码
 
<div class="container padding-big"style="min-height:200px;">
<p class="text-large">{dede:type }[field:typename/]{/dede:type}</p>
<div class="line-big">
{dede:php} 
$sql = "select arc.id,arc.writer,arc.typeid, arc.title, arc.senddate,tp.sitepath,tp.namerule,tp.typedir from dede_archives  arc  left join `arctype` tp on arc.typeid=tp.id where arc.typeid=2";
 $dsql->SetQuery($sql);
$dsql->Execute();//执行SQL操作
while($row = $dsql->GetArray()){
//print_r($row['title']);exit;
//$pingyin=GetPinyin($row['title'],0,1);
$letter=substr(GetPinyin($row['title']),0,1);//取得拼音首字母
$letter=strtoupper($letter);
$arr[$letter]['writer'][]=$row["writer"];
$arr[$letter]['url'][]=GetFileUrl($row['id'],$row['typeid'],$row['senddate'],$row['title'],0,0,$row['namerule'],$row['typedir'],0, '',0,'',$row['sitepath']);
$arr[$letter]['title'][]=$row["title"];       

ksort($arr);//字母排序
//print_r($arr);exit;
$b=1;
foreach($arr as $k=>$v){
//print_r($v);exit;
echo '<div class="x3"><p class="padding-left bg-eee st">'.strtoupper($k).'</p>';
for ($x=0; $x<count($v['title']); $x++) {
             echo '<a href="'.$v[url][$x].'"><strong>'. $v[title][$x].'</strong></a><br/><hr/>';
        }    
             echo '<br/></div>';// print_r($b%4);
             if($b%3==0){echo '<hr class="space"></hr>';//hr{background:#ddd;color:#ddd;clear:both;float:none;width:100%;height:1px;margin:10px 0;border:none;-moz-box-sizing:content-box;box-sizing:content-box;}hr.space{background:#fff;color:#fff;visibility:hidden;}hr的css,强制换行,防止错位
             }
             $b++;
             }
{/dede:php}
</div>
</div><a class="ViewSource" href="http://blog.csdn.net/viqecel/article/details/50087975#" style="font-family: Verdana, Geneva, Arial, Helvetica, sans-serif; font-size: 9px; box-sizing: border-box; color: rgb(202, 12, 22); text-decoration: none; margin: 0px 10px 0px 0px; padding: 1px; outline: none; border: none; display: inline-block; width: 16px; height: 16px; text-indent: -2000px; background-image: url("images/default/ico_plain.gif"); background-attachment: initial; background-color: inherit; background-size: initial; background-origin: initial; background-clip: initial; background-position: 0% 0%; background-repeat: no-repeat;" title="view plain">view plain</a><span class="tracking-ad" data-mod="popu_168" style="color: silver; font-family: Verdana, Geneva, Arial, Helvetica, sans-serif; font-size: 9px; box-sizing: border-box; margin: 0px; padding: 0px;"> <a class="CopyToClipboard" href="http://blog.csdn.net/viqecel/article/details/50087975#" style="box-sizing: border-box; color: rgb(202, 12, 22); text-decoration: none; margin: 0px 10px 0px 0px; padding: 1px; outline: none; border: none; font-size: 9px; display: inline-block; width: 16px; height: 16px; text-indent: -2000px; background-image: url("images/default/ico_copy.gif"); background-attachment: initial; background-color: inherit; background-size: initial; background-origin: initial; background-clip: initial; background-position: 0% 0%; background-repeat: no-repeat;" title="copy">copy</a></span>
