创建空白 PHP Table

Question

完全是新手，正在尝试编辑我的第一个 PHP 代码，非常感谢任何帮助。

我用this plugin to display nutrition labels on my WordPress site. With the creator's permission, I'm trying to update how it displays from standard vertical format to horizontal format.

我想不出如何在 PHP 中创建所需的 4 列 table。我用 Google 搜索了过去几个小时，但我发现的所有内容都是关于调用数据库项目以显示为 table。希望这是超级基本的，我只是没有正确搜索！

这是我从原始插件文件编辑的代码；我已经标记了我想要分栏符的位置。

function nutr_label_generate($id, $width = 22)
{
global $rda, $nutritional_fields;

$label = get_post_meta($id);

$insufficient = []; //holds insufficient vitamins data

if (!$label) {
    return false;
}

// GET VARIABLES
foreach ($nutritional_fields as $name => $value) {
    $$name = $label['_' . $name][0];
}

// BUILD CALORIES IF WE DON'T HAVE ANY
if ($calories == 0) {
    $calories = (($protein + $carbohydrates) * 4) + ($totalfat * 9);
}

// WIDTH THE LABEL
$style = '';
if ($width != 22) {
    $style = " style='width: " . $width . "em; font-size: " . (($width / 22) * .75) . "em;'";
}


/* First Column */


$rtn = "";
$rtn .= "<div class='wp-nutrition-label' id='wp-nutrition-label-$id' " . ($style ? $style : "") . ">\n";

$rtn .= "   <div class='heading'>" . __('Nutrition Facts', 'nutrition-facts-vitamins') . "</div>\n";


$rtn .= "   <div style='font-size: 18px; padding-top: 3px; padding-bottom: 5px'>" . $servings . " " . __('servings per container',
                'nutrition-facts-vitamins') . "</div>\n";

    $rtn .= "   </div>";
}
$rtn .= "<hr />";

$rtn .= "</div> <!-- /wp-nutrition-label -->\n\n";

return $rtn;
}

当然，我也愿意接受任何非table方式来让它看起来像水平格式！

任何help/guidance真诚的感谢。

Answer 1

我认为您可以通过添加

用 div 列包裹每个部分

$rtn .= "<div class='column' style='width:25%;float:left;'>\n";

到开头和

$rtn .= "</div>\n";

到分栏结束。这是一个起点。
