Question

我正在使用foreach（）循环插入多行数据。但是如果它的值是税或折扣，我不想插入特定的行。我该怎么做。

我的代码：

<?php
if(isset($_POST['finalsave']))
{
  foreach ($_POST['descr'] as $key => $descr)
  {
    $dept = mysql_real_escape_string($_POST['category']);
    $idate = mysql_real_escape_string($_POST['idate']);
    $desc1 = mysql_real_escape_string($descr);
    $tags = mysql_real_escape_string($_POST['name'][$key]);
    $location = mysql_real_escape_string($_POST['location'][$key]);
    $war = mysql_real_escape_string($_POST['war'][$key]);
    $qty = mysql_real_escape_string($_POST['qty'][$key]);
    $rate = mysql_real_escape_string($_POST['rate'][$key]);
    $finalamt = mysql_real_escape_string($_POST['finalamt'][$key]);

    $sql2 = ("INSERT INTO `project`.`master_inventory` (`category`, `idate`, `descr`, `name`, `location`,  `war`, `qty`, `rate`, `finalamt`)
      VALUES ('".$dept."','".$idate."','".$desc1."','".$tags."','".$location."','".$war."','".$qty."','".$rate."','".$finalamt."')");
    $sqlins = mysql_query($sql2);
    //echo $sql2;
  }
}
?>

Answer 1

希望这会对你有所帮助。

 foreach ($_POST['descr'] as $key => $descr)
  {
    if(($descr !="tax")||($descr !="discount"))
    {
       //Write your logic here
    }
}

将if条件置于foreach循环中，如下所示：

<?php
if(isset($_POST['finalsave']))
{
  foreach ($_POST['descr'] as $key => $descr) {
  // this you have to do
    if(($descr != 'tax') || ($descr != 'discount'))
    {
      $dept = mysql_real_escape_string($_POST['category']);
      $idate = mysql_real_escape_string($_POST['idate']);
      $desc1 = mysql_real_escape_string($descr);
      $tags = mysql_real_escape_string($_POST['name'][$key]);
      $location = mysql_real_escape_string($_POST['location'][$key]);
      $war = mysql_real_escape_string($_POST['war'][$key]);
      $qty = mysql_real_escape_string($_POST['qty'][$key]);
      $rate = mysql_real_escape_string($_POST['rate'][$key]);
      $finalamt = mysql_real_escape_string($_POST['finalamt'][$key]);

      $sql2 = ("INSERT INTO `project`.`master_inventory` (`category`, `idate`, `descr`, `name`, `location`,  `war`, `qty`, `rate`, `finalamt`)
        VALUES ('".$dept."','".$idate."','".$desc1."','".$tags."','".$location."','".$war."','".$qty."','".$rate."','".$finalamt."')");
      $sqlins = mysql_query($sql2);
        //echo $sql2;
    }
  }
}
?>

在插入查询之前检查值是税还是折扣。

正如您所说，表格中的descr字段包含分配给变量tax的值discount或$desc1

<?php
if(isset($_POST['finalsave']))
{
  foreach ($_POST['descr'] as $key => $descr)
  {
    $dept = mysql_real_escape_string($_POST['category']);
    $idate = mysql_real_escape_string($_POST['idate']);
    //this variable $desc1 will have the value tax or discount
    $desc1 = mysql_real_escape_string($descr);
    $tags = mysql_real_escape_string($_POST['name'][$key]);
    $location = mysql_real_escape_string($_POST['location'][$key]);
    $war = mysql_real_escape_string($_POST['war'][$key]);
    $qty = mysql_real_escape_string($_POST['qty'][$key]);
    $rate = mysql_real_escape_string($_POST['rate'][$key]);
    $finalamt = mysql_real_escape_string($_POST['finalamt'][$key]);
    //inserts only if $desc1 is not tax or discount
    if(($desc1!="tax")||($desc1!="discount")
    {
    $sql2 = ("INSERT INTO `project`.`master_inventory` (`category`, `idate`, `descr`, `name`, `location`,  `war`, `qty`, `rate`, `finalamt`)
          VALUES ('".$dept."','".$idate."','".$desc1."','".$tags."','".$location."','".$war."','".$qty."','".$rate."','".$finalamt."')");
        $sqlins = mysql_query($sql2);
    }
}
}
?>
