Question

我是Web编程的新手，尤其是在Codeigniter上。现在，我正在寻找如何从视图向控制器传递/提交数组。

视图中我的HTML脚本的这一部分：

<tr class="rowdim"> <!-- ROW 1 -->
<td><input type="text"  id="bookid1" name="book_id[]" /></td>
<td><input type="text"  id="qty1" name="qty[]" /></td>
<td><input type="text"  id="uom1" name="uom_id[]" /></td>
</tr>

<tr class="rowdim"> <!-- ROW 2 -->
<td><input type="text"  id="bookid2" name="book_id[]" /></td>
<td><input type="text"  id="qty2" name="qty[]" /></td>
<td><input type="text"  id="uom2" name="uom_id[]" /></td>
</tr>

<tr class="rowdim"> <!-- ROW 3 -->
<td><input type="text"  id="bookid3" name="book_id[]" /></td>
<td><input type="text"  id="qty3" name="qty[]" /></td>
<td><input type="text"  id="uom3" name="uom_id[]" /></td>
</tr>

我的ajax：

var det_book = document.getElementsByName("book_id[]");
var det_qty = document.getElementsByName("qty[]");
var det_uom = document.getElementsByName("uom_id[]");
var vdata = {det_book:det_book,det_qty:det_qty,det_uom:det_uom}
$.ajax({
    type:"POST",
    url:"<?php echo base_url(); ?>trans/StockIn/saveData",
    data:vdata,
    success:function(returnmsg){
        if (returnmsg=='""'){
             window.alert(msg);
         } else {
             window.alert(returnmsg);
         }
});

控制器：

 $det_book=$_POST["det_book"];
 $det_qty=$_POST["det_qty"];
 $det_uom=$_POST["det_uom"];
 $details = array();
 $index=0;
 foreach ($det_book as $baris){
 array_push($details,array(
    'book_id'=>$baris,
    'quantity'=>$det_qty[$index],
    'uom_id'=>$det_uom[$index]
));
$index++; }
$error="";
if (!$this->db->insert_batch('trx_inbound_detail',$details))
{
    $error = $this->db->error();
}

任何遗漏或我的代码有问题吗？已经在社区中搜索，但仍然没有运气。如果您还建议其他方式，请赞赏。谢谢

是的，您错过了一些东西。名称为namespace Test { public partial class Test : System.Web.UI.Page { SqlConnection con = new SqlConnection(ConfigurationSettings.AppSettings["constr"].ToString()); DataTable dt = new DataTable(); DataSet ds = new DataSet(); protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { GetDegreeName(); } } public void GetDegreeName() { try { objlog.Action = "SelectDegree"; objlog.StrName = "Sp_records"; dt = SchoolMarksheet_DataLayer.GetData(objlog); drpdegreelist.DataSource = dt; drpdegreelist.Items.Clear(); drpdegreelist.DataTextField = "Degree_Name"; drpdegreelist.DataBind(); drpdegreelist.Items.Insert(0, new ListItem("---Select Degree--- ", "0")); } catch (Exception ex) { } } public void bscitclasswise() { try { objlog.Action = "DisplayRecords"; objlog.StrName = "Sp_records"; objlog.Degree_Id = drpdegreelist.SelectedIndex; dt = SchoolMarksheet_DataLayer.GetData(objlog); if (dt.Rows.Count > 0) { Gridview.DataSource = dt; Gridview.DataBind(); ds.Tables.Add(dt); } } catch (Exception ex) { } } protected void btnprint_Click(object sender, EventArgs e) { // for viewing crystal report on button click try { CrystalDecisions.CrystalReports.Engine.ReportDocument rd = new CrystalDecisions.CrystalReports.Engine.ReportDocument(); rd.FileName = Server.MapPath("~/Report.rpt"); rd.SetDataSource(dt); CrystalReportViewer1.ReportSource= rd; CrystalReportViewer1.DataBind(); } catch(Exception ex) { } } } }的元素不存在。另外，您有三个具有相同名称的输入。检查this link，了解如何通过ajax传递数组。

Your first mistake is get the textbox value in multiple fields:

    var det_book = $('input[name^=book_id]').map(function(idx, elem) {
        return $(elem).val();
    }).get();

    var det_qty = $('input[name^=qty]').map(function(idx, elem) {
        return $(elem).val();
    }).get();

    var det_uom = $('input[name^=uom_id]').map(function(idx, elem) {
        return $(elem).val();
    }).get();

在php中，您没有在foreach中提及索引：

    foreach ($det_book as $index => $baris) {
         array_push($details,array(
            'book_id'=>$baris,
            'quantity'=>$det_qty[$index],
            'uom_id'=>$det_uom[$index]
        ));
    }

    print_r($details);
    exit();

使用Ajax（Codeigniter）从视图向控制器提交数组
