Question

我构建了一个将Service Mechanic客户存储到数据库的站点。它具有更新条目的功能。我有一个下拉选择字段工作正常（它仍然如此）。但是我在事后添加的第二个只返回空白信息。

这是我的代码。

include('connect.php');

$table='currentJobs';
$tableMap=array('Date','Name','Phone','Bike_Year','Bike_Model','Current_Status','SType','Mechanic','Revenue','Notes');

$sqlArray=array();

foreach ($tableMap AS $key){
    $sqlArray[]="`".$key."`='".mysql_real_escape_string(@$_POST[$key],$dbLink)."'";
}

$sql="UPDATE `".$table."` SET ".join(',',$sqlArray)." WHERE `id`='".$_POST['id']."'";

if (mysql_query($sql,$dbLink)){
    echo 'Data for <i>' .$_POST['Name'].'</i> was successfully updated <br />'.$sql.'.';
}
else {
    echo 'Sorry, could not process the following sql: <br /><code>'.$sql.'</code>';
    echo mysql_errno($dbLink) . ": " . mysql_error($dbLink). "\n";
}

mysql_close($dbLink);

它正在归还：

Data for Test User was successfully updated 
UPDATE `currentJobs` SET `Date`='04/14/2013',`Name`='Test User',`Phone`='1234567890',`Bike_Year`='2001',`Bike_Model`='FXD',`Current_Status`='Checked In',`SType`='',`Mechanic`='All',`Revenue`='0',`Notes`='' WHERE `id`='55'.

我的表格如下：

<form action="updated.php" method="POST" name="dataForm" id="dataForm">
<fieldset>
    <input type="hidden" name="id" value="<?php echo $row['id']; ?>"/>
    <label>Arrival<input type="text" name="Date" value="<?php echo $row['Date']; ?>"/></label><br />
    <label>Name<input type="text" name="Name" value="<?php echo $row['Name']; ?>"/></label><br />
    <label>Phone Number<input type="text" name="Phone" value="<?php echo $row['Phone']; ?>"/></label><br />
    <label>Bike Year<input type="text" name="Bike_Year" value="<?php echo $row['Bike_Year']; ?>"/></label><br />
    <label>Bike Model<input type="text" name="Bike_Model" value="<?php echo $row['Bike_Model']; ?>"/></label><br />
    <label>Current Status<!--Update Status types on two pages-->
        <select name="Current_Status" form="dataForm" value="<?php echo $row['Current_Status']; ?>">
            <option value="Checked In">Checked In</option>
            <option value="Inline For Service">Inline For Service</option>
            <option value="In Service">In Service</option>

            <option value="On Hold - Waiting To Hear From Customer">On Hold - Waiting To Hear From Customer</option>
            <option value="Test Ride">Test Ride</option>
            <option value="Completed - Awaiting Pick Up">Completed - Awaiting Pick Up</option>
            <option value="Picked Up">Picked Up</option>
        </select>
    </label><br />
    <!--update Service Type in two pages.-->
    <label>Service Type</label>
        <select name="SType" form="" value="<?php echo $row['SType']; ?>">
            <option value="Spec Service Interval">Spec Service Interval</option>
            <option value="Interim Service">Interim Service</option>
            <option value="Diagnostics">Diagnostics</option>
            <option value="Tires">Tires</option>
            <option value="Engine– Light Work (1-3 hrs)">Engine– Light Work (1-3 hrs)</option>
            <option value="Engine– Medium Work (3-8 hrs)">Engine– Medium Work (3-8 hrs)</option>
            <option value="Engine– Heavy Work (8-24 hrs)">Engine– Heavy Work (8-24 hrs)</option>
            <option value="Drivetrain– Light">Drivetrain– Light</option>
            <option value="Drivetrain - Heavy">Drivetrain - Heavy</option>
            <option value="Dyno Tune">Dyno Tune</option>
        </select>
    <br />
    <label>Mechanic Assigned<input type="text" name="Mechanic" value="<?php echo $row['Mechanic']; ?>"/></label><br />
    <label>Final Revenue<input type="text" name="Revenue" value="<?php echo $row['Revenue']; ?>"/></label><br />
    <label>Notes<input type="text" name="Notes" value="<?php echo $row['Notes']; ?>"/></label><br />
    <input type="submit" value="Update" style="color:#000000;" />
</fieldset>

为什么第二个选择不发送数据？

Answer 1

select标记没有名为value的属性。

更新

这样的事情会更有用：

<label>Service Type</label>
    <select name="SType" form="dataForm">
    <?php
    $Stypes = array(
    "Spec Service Interval",
    "Interim Service",
    "Diagnostics",
    "Tires",
    "Engine– Light Work (1-3 hrs)",
    "Engine– Medium Work (3-8 hrs)",
    "Engine– Heavy Work (8-24 hrs)",
    "Drivetrain– Light",
    "Drivetrain - Heavy",
    "Dyno Tune",
    );

    foreach($Stypes as $value){
      if ($value==$row['SType']){
        echo "<option value=\"$value\" selected=\"selected\">value</option>";  
      } else {
        echo "<option value=\"$value\">$value</option>";  
      }
    }

    ?>

    </select>

假设你从数据库中撤回$row['Stype']。

同样正如@Fred所说，如果您使用的是HTML5，则可能需要为form属性指定表单ID （尽管这在IE中不起作用...然而）。

你也可以在你正在进行插入的页面上进行print_r($_POST)调试，只是为了验证发生了什么。

选项标签中的代码将空白数据发送到数据库
