Wordpress the_excerpt显示所有id的相同数据

Question

我有一个Wordpress的购物车插件。它使用the_excerpt来显示产品描述。它适用于除结帐页面之外的所有页面。在结帐页面上，它显示了所有产品的相同说明。它显示的描述始终来自数据库中的第一个产品，即使该产品不在购物车中。我试过很多变化没有修复它。它为产品提供了正确的ID和价格，但只是描述对于al产品来说总是相同的。

 <?php the_excerpt(get_the_ID()); ?>
       <input id="item-<?php echo $item->ID; ?>-price" name="item-<?php echo $item->ID; ?>-price" type="hidden" value="<?php echo intval($price); ?>"/>

在上面的代码中，价格正确，但每个产品的__cercer都相同。

我试过了：

    <?php the_excerpt(get_the_ID()); ?>
    <?php the_excerpt($item->ID); ?>
    <?php the_excerpt(get_the_excerpt); ?>

我还试过if和while但它只是显示了每种产品的所有20个产品说明

这是该页面的所有代码：

     <script>
window.onload = calculate_order(0,0);

function calculate_order(qty_item, qty_type) {
    //qty_type could be add or substract
    total = 0;
    numberofitems = 0;
    if (qty_type == "add"){
        document.getElementById((qty_item+"-qty")).value++;
    }
    if (qty_type == "subtract") {
        if (document.getElementById((qty_item+"-qty")).value > 0) {
           document.getElementById((qty_item+"-qty")).value--;
        }
    }
    //return;
    $('.store-item').each(function(i, obj) {
        price = document.getElementById(($(this).attr("id")+"-price")).value;
        //price = price * 1 ;
        qty = document.getElementById(($(this).attr("id")+"-qty")).value;
        //qty = qty * 1;
        numberofitems = numberofitems + (qty*1);
        total         = total + ((price*1)*(qty*1));
        //alert (numberofitems);
    });
    document.getElementById("total_price").innerHTML = total ;
    document.getElementById("total_qty").value = numberofitems ;
    discount = 100*Math.floor(numberofitems/2);
    document.getElementById("total_discount").innerHTML = discount ;
    document.getElementById("final_price").innerHTML = (total - discount);
    document.getElementById("tot_discount").value = discount ;
    document.getElementById("tot_order").value = (total - discount);
    document.getElementById("tot_price").value = total ;
    if (numberofitems <2) {
        $("#total-price").hide();
        $("#total-discount").hide();
    }
    else {
        $("#total-price").show();
        $("#total-discount").show();
    }
    return;
  }

Answer 1

您无法将参数传递给the_excerpt，它总是在循环中使用＆＃34;帖子＆＃34;同样适用于get_the_excerpt（之前我错了）。通过查看代码，您将遍历每个项目并获取其对应的WP_Post对象。它的摘录应该在$item->post_excerpt

一种可能更简洁的方法是创建一个可以循环的新WP_Query。见http://codex.wordpress.org/The_Loop#Multiple_Loops
