PHP/JQUERY:1个查询，N个JSON字符串，多选择循环

php jquery json

PHP/JQUERY:1个查询，N个JSON字符串，多选择循环,php,jquery,json,Php,Jquery,Json,大家早上好。我有一个执行jquery.post的页面，返回到PHP页面，在该页面中对MySQL数据库执行查询，结果以JSON格式返回。根据查询输出，可能返回多个JSON字符串。JSON输出的一个“字段”（AppParentHcyRSYear）应该用于选择multiselect中的所有返回值，但我无法让它工作让我展示一些JSON输出，以及我到目前为止所做的尝试（为了达到这样的目的而缩短）多选（PHP）： addapp\u processajax.php if(isset($_POST['QNU

大家早上好。我有一个执行jquery.post的页面，返回到PHP页面，在该页面中对MySQL数据库执行查询，结果以JSON格式返回。根据查询输出，可能返回多个JSON字符串。JSON输出的一个“字段”（AppParentHcyRSYear）应该用于选择multiselect中的所有返回值，但我无法让它工作

让我展示一些JSON输出，以及我到目前为止所做的尝试（为了达到这样的目的而缩短）

多选（PHP）：

addapp\u processajax.php

if(isset($_POST['QNUM'])) {
    $qnum = $_POST['QNUM'];

    if ($qnum == 1) {
        $getretquery = "SELECT a.parentID, concat(a.parentFName, ' ', a.parentLName) as ParentName, a.parentDOB, a.parentPriPhone from tblParents a";
    } elseif ($qnum == 2) {
        $getretquery = "SELECT a.parentID, concat(a.parentFName, ' ', a.parentLName) as ParentName, b.childID, concat(b.childFName, ' ', b.childLName) as ChildName, a.parentDOB, b.childDOB, a.parentPriPhone from tblParents a, tblChildren b where a.parentID = b.childParentID";
    } elseif ($qnum == 3) {
        $getretquery = "SELECT a.childID, concat(a.childFName, ' ', a.childLName) as ChildName, a.childDOB from tblChildren a";
    }
    $getretqueryresults = $mysqli->query($getretquery);
    while ($row1 = $getretqueryresults->fetch_object()) {
        $rows1[] = $row1;
    }

    $ret1 = json_encode($rows1);
    print json_encode($rows1);
}

结束编辑

JSON输出示例：

代码失败#1：

var-oPHCACYrs=new-Array（）；
对于（i=0；i使用$。每个用于集合上的循环。选中
<select name="appParentHCACYrs[]" id="ParentHCACYrs" multiple="multiple" size="3">
    <option value="1">Year 1</option>
    <option value="2">Year 2</option>
    <option value="3">Year 3</option>
</select>

谢谢！我没有像上面那样做，但是“$.each”的提醒让我朝着正确的方向前进，这正是我所需要的！）
