• wordpress 添加 显示磁盘剩余空间百分比的插件


    wp-content/plugins 文件夹下

    我取的文件名是: folder-sizes-dashboard-widget.php

    在仪表盘 可以看到 Folder Sizes 标题的Box

    <?php

    通过PHP显示 磁盘剩余空间

    步骤1 - PHP代码

    替换需要统计的路径calc_root_path的值

     $calc_root_path = '/home/vagrant';
     /* get disk space free (in bytes) */
     $df = disk_free_space($calc_root_path);
     /* and get disk space total (in bytes)  */
     $dt = disk_total_space($calc_root_path);
     /* now we calculate the disk space used (in bytes) */
     $du = $dt - $df;
     /* percentage of disk used - this will be used to also set the width % of the progress bar */
     $dp = sprintf('%.2f',($du / $dt) * 100);
    
    /* and we formate the size from bytes to MB, GB, etc. */
    $df = my_custom_format_size($df);
    $du = my_custom_format_size($du);
    $dt = my_custom_format_size($dt);
    

    步骤2 - css 样式

    这是进度条的样式,你可以将这个样式代码,放入到你要存放的web路径中,让 步骤1 的php代码可以引入到这个css样式

    <style type='text/css'>
    
    .progress {
            border: 2px solid #5E96E4;
            height: 32px;
             540px;
            margin: 30px auto;
    }
    .progress .prgbar {
            background: #A7C6FF;
            position: relative;
            height: 32px;
            z-index: 999;
    }
    .progress .prgtext {
            color: #286692;
            text-align: center;
            font-size: 13px;
            padding: 9px 0 0;
             540px;
            position: absolute;
            z-index: 1000;
    }
    .progress .prginfo {
            margin: 3px 0;
    }
    
    </style>
    

    步骤3 HTML 代码

    你可以选择将这短代码放入到web 目录的一个php文件中。这个HTML代码能够放入到步骤1创建的php文件或者是独立分开的文件。

    <div class='progress'>
            <div class='prgtext'><?php echo $dp; ?>% Disk Used</div>
            <div class='prgbar'></div>
            <div class='prginfo'>
                    <span style='float: left;'><?php echo "$du of $dt used"; ?></span>
                    <span style='float: right;'><?php echo "$df of $dt free"; ?></span>
                    <span style='clear: both;'></span>
            </div>
    </div>
