Question

我希望这是小事。经过几个小时的梳理并尝试各种各样的变化后，我决定让专业人士对它进行破解。我有一个页面设置来轻松管理数据库。基本上只是更新一行或删除它。对于每一行，我都有一个用于更新行的复选框，要删除的复选框，来自数据库的三列信息，然后是带有下拉框的两列以更改值。问题是，无论我从下拉列表中选择什么值，它总是发布相同的值。使用print_r（$ _ POST）我可以看到它实际上返回了错误的值。不用多说，代码：

这是我页面的顶部（表单帖子）：

    if(isset($_POST['checkbox'])){
    $product = $_POST['product_choice'];
    $status = $_POST['status_choice'];
    $checkbox = $_POST['checkbox'];
    if(isset($_POST['update'])){
    $update = $_POST["update"];
    }
    $id = "('" . implode( "','", $checkbox ) . "');" ;
    $sql="UPDATE test_orders SET product='$product',status = '$status' WHERE ordNum IN $id" ;
    $result = mysql_query($sql) or die(mysql_error());
      }

形式：

<table width="400" border="0" cellspacing="1" cellpadding="0">
<tr>
<td><form name="frmactive" method="post" action="">
<table width="400" border="0" cellpadding="3" cellspacing="1">

<!--BUTTONS--> 

<tr>  
<td colspan="6"><input name="update" type="submit" id="update" value="Upate" />
<input name="delete" type="submit" id="delete" value="Delete" /></td>
</tr>


<tr>

<td colspan="5"><strong>Update multiple rows in mysql with checkbox</strong> </td>

这是print_r（$ _ POST）的结果;无论我在下拉菜单中选择什么选项。 [product_choice]和[status_choice]始终相同。

Array ( [update] => Upate [checkbox] => Array ( [0] => 113 ) [product_choice] => Extensive Retouch [status_choice] => Order Received )

感谢您的帮助。

Answer 1

问题是你在一个带有静态名称的循环中有一个选择

<select name="product_choice" id="product" style="font-size:10px;">

因此，您将拥有一堆具有相同名称的选择框，因此它们将相互覆盖，并且只有页面上的最后一个框才是正确的。您可以为它们指定一个唯一的名称，也可以将其作为数组。

这与您的状态相同

<select name="status_choice" id="status" style="font-size:10px;">

所以做一些像

这样的事情

<select name="status_choice[<?=$rows['id']?>]>

然后得到结果..

foreach($_POST['product_choice'] as $key => $product)
{
    $status = $_POST['status_choice'][$key];
    $sql = sprintf('UPDATE test_orders SET product = "%s", status="%s" WHERE ordNum = %s', 
        mysql_real_escape_string($product), mysql_real_escape_string($_POST['status_choice'][$key]), mysql_real_escape_string($_POST['checkbox'][$key]));
    $result = mysql_query($sql) or die(mysql_error());     
}

然后将您的复选框名称更改为checkbox[<?=$rows['product']?>]

打开foreach循环：

foreach($_POST as $key => $value) {
    if(!is_array($value)) {
        $_POST[$key] = mysql_real_escape_string($value);
    } else {
        foreach($value as $key => $value) {
            $_POST[$key][$key] = mysql_real_escape_string($value);
        }
    }
}

//print_r($_POST);

// * Delete multiple via checkboxes * START *
if(isset($_POST['delete'])) { 
    if(is_array($_POST['delete'])) {
        foreach($_POST['delete'] as $value) { 
            if(intval($value)) {
                echo 'The order number '.$value.' has been deleted';
                $sql_query = mysql_query("DELETE FROM $tbl_name WHERE ordNum = $value"); 
            }
        } 
    }
} elseif(isset($_POST['checkbox'])) {
    if(isset($_POST['product_choice'])) {
        foreach($_POST['product_choice'] as $key => $value) {
            if(intval($key)) {
                $sql_query = 'UPDATE '.$tbl_name.' SET product = "'.$_POST['product_choice'][$key].'", 
                              status = "'.$_POST['status_choice'][$key].'" WHERE ordNum = '.$key;
                echo $result = mysql_query($sql_query) or die(mysql_error()); 
            }
        }
    }
}

下拉框：

<td>
<?//php echo $rows['product']; ?>
<select name="product_choice[<?php echo $rows['ordNum']?>] id="product" style="font-size:10px;">
            <option value="<?php echo $rows['product']; ?>" selected="selected"><?php echo $rows['product']; ?></option>
            <option value="Color Correction"> Color Correction </option>
            <option value="Basic retouch"> Basic retouch </option>
            <option value="Extensive Retouch"> Extensive Retouch </option>
            <option value="Signature Work"> Signature Work </option>

            <option value="Other"> Other </option>

            <option value="<?php echo $rows['status']; ?>" selected="selected"><?php echo $rows['status']; ?></option>
            <option value="Order Received"> Order Received </option>
            <option value="in the works"> in the works </option>
            <option value="waiting to upload"> waiting to upload </option>
            <option value="uploading"> uploading </option>
