【问题描述】：
这是我的 Json 数组。我想检索子数组，我需要在项目部分下显示所有发票详细信息。请检查随附的屏幕截图。在屏幕截图中，您只能看到仅显示给所有其他项目的最后一张发票详细信息。最后一张发票编号 1005 显示给所有人。如何根据项目详细信息显示发票详细信息？
当子行为空时，项目详细信息（父）也不显示。我正在获取 projectinvoicesection: [] Array 0。我需要显示项目详细信息，但在发票部分找不到记录。但现在数组为零。
[{
"parent": {
"project_ID": "1",
"project_title": "Network and Telephone Points",
"particulars": "Test Description",
"project_amount": "10000.00",
"type": "One Time",
},
"child": [{
"invoice_No": "1002",

我已经尝试过以下代码：
for (var i = 0; i < new_data.projectinvoicesection.length; i++) {
var sl = i + 1;
//alert(t6)
var t1 = new_data.projectinvoicesection[i]['parent'].project_amount;
//alert(t1)
var t2 = new_data.projectinvoicesection[i]['parent'].particulars;
var t3 = new_data.projectinvoicesection[i]['parent'].project_ID;
var t4 = new_data.projectinvoicesection[i]['parent'].project_title;
var t5 = new_data.projectinvoicesection[i]['parent'].type;
var t56 = new_data.projectinvoicesection[i]['parent'].period_type;
var object = new_data.projectinvoicesection[i]['child'];
var tr = "<tr data-toggle='collapse' data-target='#demo" + t3 + "' style='background-color: #337ab7;color: white;' class='accordion-toggle'><td>" + sl + "</td><td>" + t4 + "</td><td>" + t1 + "</td><td style='white-space: nowrap;'>" + t5 + " " + t56 + "</td><td><button class='open-button-project-edit btn' data-toggle='modal' data-backdrop='static' data-keyboard='false' data-target='#exampleModal_2' onclick='openForm3(" + t3 + ")' style='color: #fff;background-color: #398439;border-color: #255625;'>EDIT</button></td></tr><tr><td colspan='6' class='hiddenRow'><div class='accordian-bodyproj collapse' id='demo" + t3 + "'> <table id='tableinvoice_proj' class='tableinvoice_proj' style='border-collapse:collapse;'><thead><tr><th>Invoice Date</th><th>Invoice Number</th><th>Invoice Amount</th><th>Received Amount</th><th>Generate Receipt</th></tr></thead><tbody></tbody></table>";
$("#tableproject").append(tr);
$("#tableproject").append('</div></td></tr>');
}
for (var property in object) {
//alert(object[property].invoice_No);
var t6 = format(object[property].invoice_Date);
var t7 = object[property].invoice_No;
var t8 = object[property].invoice_amount;
var t9 = object[property].received_Amt;
var t10 = object[property].proje_ID; //invoice table's project id
var trtoggle = "<tr><td>" + t6 + "</td><td>" + t7 + "</td><td>" + t8 + "</td><td class=''>" + t9 + "</td><td class=''><input type='checkbox' name='myTextEditBox' value='checked' /> checkbox</td></tr>";
$(".tableinvoice_proj").append(trtoggle);
}
PHP 模式：
public function list_all_projects_invoice($data) //project section display with ALL Category
{
$array_store = array();
foreach($this->one_allcategory($data) as $row) {
$child = $this->many_allcategory($row['project_ID']);
if($child) {
$return = array_merge(array("parent" => $row), array("child" =>$child));
array_push($array_store, $return);
}
}
return $array_store;
}
public function one_allcategory($data) {
$query = $this->db->select("*")
->where("comp_ID", $data)
->get("project_details")
->result_array();
return $query;
}
public function many_allcategory($id) {
$query = $this->db->select('invoice_No,received_Amt,invoice_amount,proje_ID,invoice_Date')
->where("proje_ID", $id)
->get("invoice_details")
->result_array();
return $query;
}

我更新了我的答案，我展示了如何检查项目信息的空白

提示：
one_allcategory更专业地写成：public function one_allcategory(int $compId): array { return $this->get_where("project_details", ["comp_ID", $compId])->result_array(); }也就是说，您的脚本正在迭代模型方法调用（这意味着对数据库的迭代之旅——这是一个禁忌。您应该创建一个单一的模型方法，该方法只使用一个使用连接的 sql 查询访问数据库。该结果集应该转换为您确切想要的数组结构并传递回控制器以传递给视图。跨度>
