织梦在PHP7.0环境中为文章图片自动添加ALT属性为标题方法,首先修改/include/extend.func.php,里面的把这段代码加进去:
//文章body优化替换
function replaceurl($newurl)
{
global $dsql,$id;
//获取图片附加表imgurls字段内容进行处
$row = $dsql->GetOne("SELECT title FROM dede_archives where id=$id");
//替换图片Alt为文档标题
$newurl=str_ireplace(array('alt=""','alt=\'\'')]'',$newurl);
$newurl=preg_replace("@ [\s,{0]}alt[\s,{0]}=[\"'\s,{0]}[\s\S,{0]}[\"'\s, @isU"," ",$newurl);
$newurl=str_ireplace("[i,","/>",$newurl);
return $newurl;
}
然后在我们需要调用织梦文章内容的地方加上调用代码:
{dede:field.body function='replaceurl(@me)'/}
由于之前在《织梦如何去除img图片中的style width height属性》一文中,实现去高宽属性,既然我们今天用自定义函数实现了替换alt属性,那么也可以把去高宽属性的这个功能加进去,完整代码如下:
//文章body优化替换
function replaceurl($newurl)
{
global $dsql,$id;
//获取图片附加表imgurls字段内容进行处
$row = $dsql->GetOne("SELECT title FROM dede_archives where id=$id");
//去掉img的width和height
$newurl=preg_replace('/style=\"width\:(.*)\"/','',$newurl);
//替换图片Alt为文档标题
$newurl=str_ireplace(array('alt=""','alt=\'\'')]'',$newurl);
$newurl=preg_replace("@ [\s,{0]}alt[\s,{0]}=[\"'\s,{0]}[\s\S,{0]}[\"'\s, @isU"," ",$newurl);
$newurl=str_ireplace("[i,","/>",$newurl);
return $newurl;
