打開 wp-includes下的post-template.php

先將代碼加到 post-template.php 第一行

function RndString($body)
{
//最大間隔距離(如果在檢測不到p標(biāo)記的情況下，加入混淆字串的最大間隔距離)
$maxpos = 1024;
//font 的字體顏色
$fontColor = “#FFFFFF”;
//div span p 標(biāo)記的隨機樣式

$st3 = chr(mt_rand(ord(”A”),ord(”Z”))).chr(mt_rand(ord(”a”),ord(”z”))).chr(mt_rand(ord(”a”),ord(”z”))).mt_rand(100,999);
$st4 = chr(mt_rand(ord(”A”),ord(”Z”))).chr(mt_rand(ord(”a”),ord(”z”))).chr(mt_rand(ord(”a”),ord(”z”))).mt_rand(100,999);
$rndstyle[1]["value"] = “.{$st1} { display:none; }”;

//以后內(nèi)容如果你不懂其含義，請不要改動
//—————————————————
$rndstyleValue = $rndstyle[$mdd]["value"];
$rndstyleName = $rndstyle[$mdd]["name"];
$reString = “<style> $rndstyleValue </style> “;
//附機標(biāo)記

}
if(ereg(”#start#”,$v)){ $start = 1; }
}
fclose($fp);
//處理要防采集的字段
$bodylen = strlen($body) - 1;
$prepos = 0;
for($i=0;$i<=$bodylen;$i ){
if($i 2 >= $bodylen || $i<50) $reString .= $body[$i];
else{

if($ntag==”</p” || ($ntag==”<br” && $i-$prepos>$maxpos) ){
$dd = mt_rand(1,4);

$reString .= $rnstr.$body[$i];
$prepos = $i;
}
else $reString .= $body[$i];
}
}
unset($body);
return $reString;
}//函數(shù)結(jié)束

查找

function the_content(

將這段代碼

function the_content($more_link_text = “(more…)”, $stripteaser = 0, $more_file = “”) {
$content = get_the_content($more_link_text, $stripteaser, $more_file);
$content = apply_filters(”the_content”, $content);
$content = str_replace(”]]>”, “]]>”, $content);
echo $content;
}

改成

function the_content($more_link_text = “(more…)”, $stripteaser = 0, $more_file = “”) {
$content = get_the_content($more_link_text, $stripteaser, $more_file);
$content = apply_filters(”the_content”, $content);
$content = str_replace(”]]>”, “]]>”, $content);
$content = RndString($content);
echo $content;
}

注意,就多了行 $content = RndString($content);
