php - 捐赠名单 - 代码问题？代码有问题

问题描述

当人们在页面中多次捐款时，它只显示他们最近的捐款，而不是他们的总捐款（在捐款列表中）。例如，如果我现在捐 5 美元，以后再捐 10 美元，它只会显示 10 美元而不是 5 美元。这是网站：gesher-jds.org/giving-tuesday

我如何解决它？

<div class="donors_info">
    <div class="totalenteries"></div>
    <?php
        $valueid = 2727;
        //Get donors based on forms IDs (can be single or multiple forms)
        if(function_exists('give_get_payments')) {
            $args = array(
                'give_forms' => $valueid,
                'number' => -1,
            );
            $donations = give_get_payments( $args );

            echo "<table id='dtab'>";
            echo "<thead>";
            echo "<th align='center'>" . 'Name' . "</th>";
            echo "<th align='center'>" . 'Amount' . "</th>";
            echo "</thead>";
            echo "<tbody>";
            $donors = array();
            foreach($donations as $donation) {                              
                //Now get donor information from this donation ("customer" aka "donor")
                $customer_id = give_get_payment_customer_id( $donation->ID );
                $customers    = new Give_Customer( $customer_id );

                $nameis = $customers->name;
                if (in_array($nameis, $donors)) {} else {   
                    $amt = get_post_meta($donation->ID,'_give_payment_total',true) + 0;         
                    echo "<tr class='select'>";
                    echo "<td align='left'>" . $nameis . "</td>";
                    echo "<td align='center'>" . $purchaseis = "$" . $amt . "</td>";
                    echo "</tr>";
                    $donors[] = $nameis;
                }
            }
            echo "</tbody>";
            echo "</table>";
        }
    ?>
</div>

解决方案

$amt = get_post_meta($donation->ID,'_give_payment_total',true)

“true”仅返回指定元键的第一个值，“false”将为您提供元值数组。您可以使用 foreach 迭代返回的数组。

https://developer.wordpress.org/reference/functions/get_post_meta/

编辑：

是的，您需要将其更改为 false，然后您将获得一组值。现在你只得到一个值。

然后迭代数组：

$amt = get_post_meta($donation->ID,'_give_payment_total',false);
foreach ($amt as as $key => $value) { 
    echo "<tr class='select'>";
    echo "<td align='left'>" . $nameis . "</td>";
    echo "<td align='center'>" . $purchaseis = "$" . $value . "</td>";
    echo "</tr>";
}

代码未经检查，但这是要走的路。关于foreach的一些信息：

编辑 2：如果您想在一行中显示所有捐款：

<div class="donors_info">
<div class="totalenteries"></div>
<?php
    $valueid = 2727;
    //Get donors based on forms IDs (can be single or multiple forms)
    if(function_exists('give_get_payments')) {
        $args = array(
            'give_forms' => $valueid,
            'number' => -1,
        );
        $donations = give_get_payments( $args );

        echo "<table id='dtab'>";
        echo "<thead>";
        echo "<th align='center'>" . 'Name' . "</th>";
        echo "<th align='center'>" . 'Amount' . "</th>";
        echo "</thead>";
        echo "<tbody>";
        $donors = array();
        $dtmp=array(); //tmp array
        foreach($donations as $donation) {
            //Now get donor information from this donation ("customer" aka "donor")
            $customer_id = give_get_payment_customer_id( $donation->ID );
            $customers  = new Give_Customer( $customer_id );
            $nameis = $customers->name;

            $amt = get_post_meta($donation->ID,'_give_payment_total',false);
            $donationAll = 0;
            foreach ($amt as $key => $value) { 
                $donationAll = $donationAll + $value;
            }
            //Write a tmp array with name as key and donation as value
            if(array_key_exists($nameis,$dtmp)) {
                //name already exists -> add donation value
                $dtmp[$nameis] = $dtmp[$nameis] + $donationAll;
            } else {
                //name is not in the array -> new array: key name -> donation
                $dtmp[$nameis] = $donationAll;
            }

            $donors[] = $nameis;
        }

        foreach ($dtmp as $key => $value) {
            //iterate the tmp array
            echo "<tr class='select'>";
            echo "<td align='left'>" . $key . "</td>";
            echo "<td align='center'>" . $purchaseis = "$" . $value . "</td>";
            echo "</tr>";
        }

        echo "</tbody>";
        echo "</table>";
    }   
?>
</div>
