更新時(shí)間:2018-09-28 來(lái)源:黑馬程序員技術(shù)社區(qū) 瀏覽量:
dedecms其實(shí)在架構(gòu)方面沒什么問題,但是估計(jì)里面有些功能是新手做的吧,有很多待完善的地方,比如分頁(yè)功能,從代碼可以直接看出當(dāng)時(shí)的負(fù)責(zé)人有敷衍了事的心里。
dede的分頁(yè)如果有兩個(gè)頁(yè)碼顯示的話,無(wú)法顯示出總的文章數(shù),舉個(gè)例子:
在普通文章模型下面,列表的分頁(yè)是這樣的:
但是在獨(dú)立模型中就成了這樣了
最后面的共*頁(yè)*條的信息不見了,相信遇到這個(gè)問題的同學(xué)首先想到的是自己哪里用錯(cuò)了,其實(shí)不是,dede獨(dú)立模型這里的代碼是偷工減料了的。處理獨(dú)立模型列表的代碼在arc.sglistview.class.php中,我們比較下同樣負(fù)責(zé)顯示分頁(yè)的代碼段,獨(dú)立模型和普通模型中有什么區(qū)別:

仔細(xì)觀察 普通模型中在28行左右的位置多了句$maininfo = "<li><span class=\"pageinfo\">共 <strong>{$totalpage}</strong>頁(yè)<strong>".$this->TotalResult."</strong>條</span></li>\r\n";而在獨(dú)立模型中則沒有。
而且在最后,普通模型中將$maininfo的值加入了$plist字符串中。(更細(xì)節(jié)的地方是普通模型還判斷了標(biāo)簽中是否有info屬性來(lái)決定是否加入:
if(preg_match('/info/i', $listitem)) $plist .= $maininfo;
)獨(dú)立模型中這些都省了。
要將獨(dú)立模型修改過(guò)來(lái)很簡(jiǎn)單,不過(guò)“普通模型還判斷了標(biāo)簽中是否有info屬性來(lái)決定是否加入”這點(diǎn)我就不去實(shí)現(xiàn)了,這里不判斷直接再任何情況下都加入maininfo:
