通过 html table 更新 sql 基础

Question

我有这个 table:

<table id="skuTable" role="grid">
    <thead>
        <th class="skuRow">Orden</th>
         <th class="skuRow">Maquina</th>
        <th>Fecha Fab.</th>
        <th class="skuRow">Norden</th>
        <th>Color</th>
        <th>Cliente</th>
        <th>Metros</th>
        <th>Tiempo</th>
        <th>Fecha Ent.</th>
        <th>Operario</th>
        <th class="skuRow">Editar</th>
    </thead>
    <tbody>

SQL查询：

<?php
$sql = "SELECT DISTINCT  Orden, FFab, N_Orden=Ordenes.OF_N_Orden, Color, Client, Metros, Tiempo, FEnt,Operario
        FROM ((
                Ordenes INNER JOIN VCLIENTE ON VCLIENTE.Clie_codigo = Ordenes.OF_Cod_Cli
            ) INNER JOIN ARTITTEC ON ARTITTEC.Tec_codigo = Ordenes.OF_Cod_Art
        ) 
        INNER JOIN VTiempos ON  VTiempos.Of_n_orden= Ordenes.OF_N_Orden 
            AND Vtiempos.OF_LIN =Ordenes.OF_Lin
        ORDER BY Orden asc, Fecha asc";

$stmt = sqlsrv_query($conn, $sql);
if ($stmt === false) {
    die(print_r(sqlsrv_errors(), true));
}

while ($row = sqlsrv_fetch_array($stmt, SQLSRV_FETCH_ASSOC)){
?>

我连续打印结果，通过函数

确定我要带去POST的3个

在php的末尾，我添加了以下功能，用POST必须发送的3个数据到update41.php来更新数据：

// ----- Edit Row -----

$(document).on("click", "#skuTable .edit", function () {
  var $this = $(this);
  var tds = $this.closest('tr').find('td').filter(function () {
    return $(this).find('.edit').length === 0;
  });
  if ($this.val() === 'Edit') {
    $this.val('Save');
   if($this.id !== '.sku_group') {
        tds.prop('contenteditable', true);
   }
  } else {
    var isValid = true;
    var errors = '';
    $('#myDialogBox').empty();
    var elements = tds;
    if (tds.find('input').length > 0) {
      elements = tds.find('input');
    }
    var dict = {}; 
    elements.each(function (index, element) {
      var type = $(this).attr('class');
      var value = (element.tagName == 'INPUT') ? $(this).val() : $(this).text();
      console.log(type);
      // ----- Switch statement that provides validation for each table cell -----
      switch (type) {
        case "group_id":
              dict["Group_ID"] = value;
          break;
        case "sku_group":
              dict["SKU Group"] = value;
          break;
           case "sku_maquina":
              dict["SKU Maquina"] = value;
          break;
      }
    })
    if (isValid) {
        console.log(dict);
      $this.val('Edit');
      tds.prop('contenteditable', false);
      var request = $.ajax({
          type: "POST",
          url: "update41.php",
          data: dict
        });

        request.done(function (response, textStatus, jqXHR){
          if(JSON.parse(response) == true){
            console.log("row updated");
          } else {
            console.log("row failed to updated");
            console.log(response);
            console.log(textStatus);
            console.log(jqXHR);
          }
        });

        // Callback handler that will be called on failure
        request.fail(function (jqXHR, textStatus, errorThrown){
            // Log the error to the console
            console.log(textStatus);
            console.log(jqXHR);
            console.error(
                "The following error occurred: "+
                textStatus, errorThrown
            );
        });

        // Callback handler that will be called regardless
        // if the request failed or succeeded
        request.always(function () {

        });
    } else {
      alert(errors);
    }
  }
});

</script>

update41.php:

<?php

  $Orden = $_POST['SKU Group'];
  $NOrden = $_POST['Group_ID'];
  $Maquina =$_POST['SKU Maquina'];



  $host="xxxxx"; 
  $dbName="xxxxx"; 
  $dbUser="xxxxx"; 
  $dbPass="xxxxx";

  $pdo = new PDO("sqlsrv:server=".$host.";Database=".$dbName, $dbUser, $dbPass);

  $sql = "UPDATE Ordenes SET OF_OrdenOFs = '$Orden' WHERE OF_N_Orden = '$NOrden'";

  $stmt = $pdo->prepare($sql);
  //$stmt->bindValue('[:SKU Group]', $SKU);
  //$stmt->bindValue(':Group_ID', $Group_ID)  
  $result = $stmt->execute();
  echo json_encode($result);
  if(!$result) {
      echo json_encode(sqlsrv_errors());
  }


   $sql2 = "UPDATE VTiempos SET Maquina = '$Maquina' WHERE Of_n_orden = '$NOrden'";

  $stmt2 = $pdo->prepare($sql2);
  //$stmt->bindValue('[:SKU Group]', $SKU);
  //$stmt->bindValue(':Group_ID', $Group_ID)  
  $result2 = $stmt2->execute();
  echo json_encode($result2);
  if(!$result2) {
      echo json_encode(sqlsrv_errors());
  }

?>

按下保存时控制台中出现以下数据：

sku_group
41prueba.php:459 undefined
41prueba.php:459 sku_maquina
41prueba.php:459 undefined
41prueba.php:459 group_id
2141prueba.php:459 undefined
41prueba.php:474 {SKU Group: "", SKU Maquina: "41", Group_ID: "129236"}

v.handle @ jquery-1.10.2.min.js:5

这里可以看到它从我按下保存以放置控制台示例的行中获取字段：

41prueba.php:474 {SKU Group: "", SKU Maquina: "41", Group_ID: "129236"}

我不明白为什么它不将数据传递给 update41.php

非常感谢，请原谅我的英语

Answer 1

看起来你的 elements 变量是输入的集合，但你的 HTML 可能没有任何输入，除了一个按钮。

此外，如果您想通过 HTML 传递任意数据，标准方法是使用 data- 属性，例如 data-type。通过类似 class 的方式传递它是非常有限的（并且对于阅读代码的任何人来说都不清楚）。

Answer 2

错误是在这部分函数中：

case "group_id":
              dict["Group_ID"] = value;
          break;
        case "sku_group":
              dict["SKU Group"] = value;
          break;
           case "sku_maquina":
              dict["SKU Maquina"] = value;
          break;

SKU Maquina 和 SKU Group 不必分开（无空白 space）。

正确的是（加_）：

case "group_id":
              dict["Group_ID"] = value;
          break;
        case "sku_group":
              dict["SKU_Group"] = value;
          break;
           case "sku_maquina":
              dict["SKU_Maquina"] = value;
          break;

所以在 update41.php 中你必须把它写成相同的:

$NOrden = $_POST['Group_ID'];

$Orden = $_POST['SKU_Group'];

$Maquina =$_POST['SKU_Maquina'];
