重庆网站建设小编为您讲解当PHP版本高于5.5时,织梦DedeCMS无法使用关键词內链,下面是此问题的解决方法。
打开 /include/arc.archives.class.php 找到
$body = @preg_replace_callback("#(^|>)([^<]+)(?=<|$)#sU", "_highlight('\\2', \$karr, \$kaarr, '\\1')", $body);
改成
|
global $cfg_replace_num; |
|
if($cfg_replace_num > 0) |
|
{ |
|
$query = "SELECT char_length(keyword) AS num,aid,keyword,rpurl,rank FROM dede_keywords WHERE rpurl<>'' ORDER BY num DESC"; |
|
$this->dsql->SetQuery($query); |
|
$this->dsql->Execute(); |
|
while($row = $this->dsql->GetArray()) |
|
{ |
|
$key = trim($row['keyword']); |
|
$key_url=trim($row['rpurl']); |
|
$body = str_replace_limit($key, "<a href='$key_url' target='_blank'><u>$key</u></a>", $body, $cfg_replace_num); |
|
} |
|
} |
|
else |
|
{ |
|
$query = "SELECT char_length(keyword) AS num,aid,keyword,rpurl,rank FROM dede_keywords WHERE rpurl<>'' ORDER BY num DESC"; |
|
$this->dsql->SetQuery($query); |
|
$this->dsql->Execute(); |
|
while($row = $this->dsql->GetArray()) |
|
{ |
|
$key = trim($row['keyword']); |
|
$key_url=trim($row['rpurl']); |
|
$body = str_replace($key, "<a href='$key_url' target='_blank'><u>$key</u></a>", $body); |
|
} |
|
} |
继续找到
//高亮专用
在它上面加入
|
//指定替换次数功能 |
|
function str_replace_limit($search, $replace, $subject, $limit) |
|
{ |
|
if(is_array($search)) |
|
{ |
|
foreach($search as $k=>$v) |
|
{ |
|
$search[$k] = '#(?<!>)(?!<)'. preg_quote($search[$k], '#'). '#'; |
|
} |
|
} |
|
else |
|
{ |
|
$search = '#(?<!>)(?!<)'. preg_quote($search, '#'). '#'; |
|
} |
|
return preg_replace($search, $replace, $subject, $limit); |
|
} |
完成
