Question

下面的PHP / AJAX / JS中的foreach是多次显示一组结果，而不是每次显示两次结果。我必须使用foreach来实现我正在寻找的最终结果，但这并不是显示所有信息。

$entries = [];
$entries['id'] = get_the_id();
$entries['fname'] = get_field('fname');
$entries['lname'] = get_field('lname');
$entries['custid'] = get_field('customer_id');
$entries['company'] = get_field('company');
$entries['addr1'] = get_field('address_line_1');
$entries['addr2'] = get_field('address_line_2');
$entries['city'] = get_field('city');
$entries['state'] = get_field('state');
$entries['zip'] = get_field('zip');


<script>
function populateFields() {
    alert('Gathering representatives...');
    $.ajax({
        type: "POST",
        url: "form-shipping.php",
        data: <?php foreach($entries as $entry){?>
            {
                "id": <?php echo $entry['id'];?>,
                "fname": <?php echo $entry['fname'];?>,
                "lname": <?php echo $entry['lname'];?>,
                "custid": <?php echo $entry['custid'];?>,
                "company": <?php echo $entry['company'];?>,
                "addr1": <?php echo $entry['addr1'];?>,
                "addr2": <?php echo $entry['addr2'];?>,
                "city": <?php echo $entry['city'];?>,
                "state": <?php echo $entry['state'];?>,
                "zip": <?php echo $entry['zip'];?>,
            } ;
        <?php } ?>
        dataType: 'text';
        success function (){

        }
    });
    //if option value is equal to $ID, echo fields that match $ID
    ...

我的结果是

<script>
    function populateFields() {
        alert('Gathering representatives...')
        $.ajax({
          type: "POST",
          url: "form-shipping.php",
          data: {

如果您的数组示例准确，则您只创建了一维数组。 foreach期望迭代多维数组。

例如：

$entries[0]['id'] = get_the_id();
$entries[0]['fname'] = get_field('fname');
$entries[1]['id'] = get_the_id();
$entries[1]['fname'] = get_field('fname');
$entries[2]['id'] = get_the_id();
$entries[2]['fname'] = get_field('fname');

等

和/或，如果你正在构建一个多维数组（但没有告诉我们你是为了简洁），那么如果你用$entries = [];开始每个构建，你就可以有效地重置数组回空。
