我有一个插件，可以设置每个产品的最小和最大订购量。我想从插件中获取最小数量，并在“添加到购物车”按钮下显示为文本。我已经在代码“////显示最小数量”的末尾添加了函数，但这不起作用。有什么帮助吗？

以下是插件代码：

<?php
add_action(\'add_meta_boxes\', \'wc_mmax_meta_box_create\');
add_action(\'save_post\', \'wc_mmax_save_meta_box\');
function wc_mmax_meta_box_create()
{
    add_meta_box(\'wc_mmax_enable\', __(\'Min Max Quantity\', \'wcmmax\'), \'wc_mmax_meta_box\', \'product\', \'side\');
}

function wc_mmax_meta_box($post)
{
    wp_nonce_field(\'wc_mmax_cst_prd_nonce\', \'wc_mmax_cst_prd_nonce\');

    echo \'<p>\';
    echo \'<label for="_wc_mmax_prd_opt_enable" style="float:left; width:50px;">\' . __(\'Enable\', \'wcmmax\') . \'</label>\';
    echo \'<input type="hidden" name="_wc_mmax_prd_opt_enable" value="0" />\';

    echo \'</p>\';
    echo \'<p>\';
    $max = get_post_meta($post->ID, \'_wc_mmax_max\', true);
    $min = get_post_meta($post->ID, \'_wc_mmax_min\', true);
    echo \'<label for="_wc_mmax_min" style="float:left; width:50px;">\' . __(\'Min Quantity\', \'wcmmax\') . \'</label>\';
    echo \'<input type="number" id="_wc_mmax_min" class="short" name="_wc_mmax_min" value="\' . $min . \'" />\';
