在網(wǎng)上隨便看了一下有很多這類的文章,幾乎每一種方法都有它的可用之處了,下文我整理了我覺得還不錯(cuò)的全站最新文章調(diào)用方案,大家一起參考.

修改 phpcms/modules/content/classes/content_tag.class.php 在最后面的 },上面添加以下代碼:

public function newcontent($data){

  $num = intval($data['limit']) ? intval($data['limit']) : '20';

  // 設(shè)置排序

  switch($data['order']){

  case '1':

  $order = ' `id` ASC ';

  break;

  case '2':

  $order = ' `id` DESC ';

  break;

  case '3':

  $order = ' `inputtime` ASC ';

  break;

  case '4':

  $order = ' `inputtime` DESC ';

  break;

  case '5':

  $order = ' `updatetime` ASC ';

  break;

  case '6':

  $order = ' `updatetime` DESC ';

  break;

  default:

  $order = ' `id` DESC ';

  }

  if($data['catid']){

  $catids = explode(',', $data['catid']);

  foreach($catids as $catid){

  $catid = intval($catid);

  if(emptyempty($catid))continue;

  $this->set_modelid($catid);

  $where = $this->category[$catid]['child'] ? ' `catid` IN ('.$this->category[$catid]['arrchildid'].')' : " `catid` = $catid";

  $datas = $this->db->select($where, '*', $num, $order);

  $data[$catid]['data'] = $datas;

  // 記錄本次的文章數(shù)

  $data['num'][] = count($datas);

  $model_num++;

  }

  }else{

  $models = getcache('model', 'commons');

  foreach($models as $model){

  $this->db->set_model($model['modelid']);

  $datas = $this->db->select('', '*', $num, $order);

  $data[$model['modelid']]['data'] = $datas;

  // 記錄本次的文章數(shù)

  $data['num'][] = count($datas);

  $model_num++;

  }

  }

  if($data){

  // 獲取每個(gè)模型應(yīng)該截取的條數(shù)

  $num = ceil($num/$model_num);

  // 循環(huán)條數(shù)記錄用于找出條數(shù)不滿足的數(shù)量然后進(jìn)行平均

  $w_num = $w_num_t = '';

  foreach($data['num'] as $num_t){

  if($num_t < $num){

  $w_num += $num-$num_t;

  $w_num_t++;

  }

  }

  // 判斷是否有不滿足平均數(shù)的如果有那么就增加平均值

  if($w_num_t){

  $num += ceil($w_num/($model_num-$w_num_t));

  }

  $datas = array();

  foreach($data as $r){

  $r_n = '';

  if(is_array($r['data']))

  foreach($r['data'] as $r_t){

  $datas[] = $r_t;

  if(++$r_n == $num)break;

  } //開源軟件:Vevb.com

  }

  return $datas;

  }else{

  return false;

  }

  }

然后我們?cè)谛枰{(diào)用全站最新的頁面中調(diào)用下面的標(biāo)簽:

{pc:content action=”newcontent” num=15}

<ul >

{loop $data $r}<li><span class=”date”>{date(‘m-d’,$r[inputtime])}</span> <a href=”{$r['url']}” target=”_blank”>{str_cut($r[title],57,”)}</a></li>{/loop}

</ul>

{/pc}

這樣就可以獲取到全站最新的15條數(shù)據(jù),默認(rèn)是調(diào)用20條最新,如果不設(shè)置.

catid:可有可無加了就只調(diào)用指定欄目的信息多個(gè)欄目請(qǐng)使用英文半角的 ,間隔

order:排序參數(shù)值：1-7 具體的含義在代碼里面很容易看明白不祥述

num:調(diào)用數(shù)量不指定默認(rèn)調(diào)用20條

還有一種方案,代碼放置的位置是不一樣的。

V9的模型使用分表儲(chǔ)存,調(diào)用多個(gè)模型下的最新內(nèi)容使用GET來IN catid卻要連表查詢十分麻煩,所以使用下面的辦法即可.

第一步:

phpcms/libs/functions/extention.func.php

里面增加如下代碼:

function news($limit="",$modelid="",$where="")

{

  $db=pc_base::load_model('content_model');

  if((strpos($modelid,",")>=0))

  {

   $modelid=explode(",",$modelid);

   $midarr=$dot='';

   foreach($modelid as $mid)

   {

    $midarr=$midarr.$dot.$mid;

    $dot=',';

   }

   $sq="`modelid` IN ({$midarr})";

  }

  else

  {

   $sq="`modelid`={$modelid}";

  }

  $db->table_name='v9_model';

  $models=$db->select($sq,"tablename");

  $sql='';

  $lianhe='';

  foreach($models as $name)

  {

   $sql=$sql.$lianhe."SELECT id,catid,title,url,inputtime FROM v9_{$name['tablename']}";

   $lianhe=' UNION ALL ';

  }

  $time=time();

  $sql=$sql." ".$where." order by inputtime desc limit  ".$limit;

  $allnews=$db->query($sql);

  while($r = $db->fetch_array($allnews))

  {//開源軟件:Vevb.com

   if($keyfield)

   {

    $key = $r[$keyfield];

    $array[$key] = $r;

   }

   else

   {

    $array[] = $r;

   }

  }

  return $array[0];

}

以上代碼需要注意的是里面表前綴,這里是V9,使用的時(shí)候改成你自己的表前綴,默認(rèn)是V9.

第二步:

調(diào)用的方式為:

<?php $recent=news(“0,8“,”1,12“);?>

{loop $recent $r}

<li><a href=”{$r['url']}” target=”_blank” title=”{$r['title']}”>{str_cut($r[title],54,”)}</a></li>

{/loop}

{/pc}
