dedecms织梦获得首字母或拼音的方法,并实现文章列表按首字母归类

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  

 

 

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;   

}  

 

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 `dede_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>
