如何在PHP中更改行的位置？

Question

如何在PHP中更改行的位置？我正在尝试在woocommerce产品描述选项卡中添加自定义文本行。但这是账单的最后一笔。我想要这一页顶端的那行。我该怎么做呢？

我正在使用这个代码。

add_filter( 'the_content', 'customizing_woocommerce_description' );
function customizing_woocommerce_description( $content ) {
    // Only for single product pages (woocommerce)
    if ( is_product() ) {

        // The custom content
        $custom_content = '<p class="custom-content">' . __("This is the last line in the description", "woocommerce").'</p>';

        // Inserting the custom content at the end
        $content .= $custom_content;
    }
    return $content;
}

Answer 1

$content .= $custom_content的意思是$content = $content . $custom_content;

如果我理解正确的话，你可能需要这个：

$content = $custom_content . $content;

So，完整代码：

// Only for single product pages (woocommerce)
if ( is_product() ) {

    // The custom content
    $custom_content = '<p class="custom-content">' . __("This is the last line in the description", "woocommerce").'</p>';

    // Inserting the custom content at the end
    $content = $custom_content . $content;
}
return $content;
