PHPCMS模板制作笔记

- 阅读剩余部分 -

织梦dedecms中仅channel支持currentstyle属性，实际使用中往往需要channelartlist添加currentstyle，修改如下：
修改include\taglib\channelartlist.lib.php第93行$pv->Fields['typeurl'] = GetOneTypeUrlA($typeids[$i]);新增（其中'ON'为设置的样式类）：

中文等多字节字符串翻转

$str = '字符串反转';

function rev($str, $encoding = 'utf-8'){
    $len = mb_strlen($str, $encoding);
    $result = '';

    for ($i = $len-1; $i>=0; $i--){
        $result.= mb_substr($str,$i,1,$encoding);
    }

    return $result;
}

echo rev($str);

生成圆形头像：

test('2.jpg','1.jpg'); #2原图 1生成图
function test($url,$path='./'){  
    $w = 100;  $h=100; // original size  
    $original_path= $url;  
    $dest_path = $path.uniqid().'.png';  
    $src = imagecreatefromstring(file_get_contents($original_path));  
    $newpic = imagecreatetruecolor($w,$h);  
    imagealphablending($newpic,false);  
    $transparent = imagecolorallocatealpha($newpic, 0, 0, 0, 127);  
    $r=$w/2;  
    for($x=0;$x<$w;$x++)  
        for($y=0;$y<$h;$y++){  
            $c = imagecolorat($src,$x,$y);  
            $_x = $x - $w/2;  
            $_y = $y - $h/2;  
            if((($_x*$_x) + ($_y*$_y)) < ($r*$r)){  
                imagesetpixel($newpic,$x,$y,$c);  
            }else{  
                imagesetpixel($newpic,$x,$y,$transparent);  
            }  
        }  
    imagesavealpha($newpic, true);  
    imagepng($newpic, $dest_path);  
    imagedestroy($newpic);  
    imagedestroy($src);  
   // unlink($url);  
    return $dest_path;

如果当前为2018-01-29则通过echo date("Y-m",strtotime("+1 month"));则会得出3月的错误结果

function GetMonth($sign="1")  
{  
    //得到系统的年月  
    $tmp_date=date("Ym");  
    //切割出年份  
    $tmp_year=substr($tmp_date,0,4);  
    //切割出月份  
    $tmp_mon =substr($tmp_date,4,2);  
    $tmp_nextmonth=mktime(0,0,0,$tmp_mon+1,1,$tmp_year);  
    $tmp_forwardmonth=mktime(0,0,0,$tmp_mon-1,1,$tmp_year);  
    if($sign==0){  
        //得到当前月的下一个月   
        return $fm_next_month=date("Ym",$tmp_nextmonth);          
    }else{  
        //得到当前月的上一个月   
        return $fm_forward_month=date("Ym",$tmp_forwardmonth);           
    }  
}  

echo GetMonth('0');

chrome input required display:none

开机后无win10进入选项，终端：
sudo gedit /etc/default/grub
修改
GRUB DEFAULT=0=>4
更新grub
sudo update-grub
此时在终端即可看到win10字样，重启即可自动进入win10，选择系统即可。

双屏无显示问题需要安装英伟达驱动即可，搜索“附加驱动”即可安装
声音解决：
下载pulseaudio音量控制软件
sudo apt install pavucontrol
终端输入：pavucontrol

配置：HDA NVidia 侧写改为“关”，内置音频“模拟立体声双工”
输出设备 port设置为“模拟耳机”
