    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
    POST TIME:2021-05-24 03:11

    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 view plai copy
    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;   
    }view plain cop

    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>view plain copy
