遇到 php 格式不正确的数值

Question

我从数据库中传递日期并设置 dateforService 的值，然后我将 URL 值发送到另一个 php 文件以更新数据库。但是每次我尝试在数据库中保存时，它都会保存为 0000-00-00。

代码如下：

echo "<td><input type= 'text' name = 'jobrequestnumber' value =".$row['jobrequestnumber']."></td>"  ; // results in the same jobrequestnumbers
echo "<td><input type= 'text' name = 'requestingcompany' value =".$row['requestingcompany']."></td>"    ;//this too
echo "<td><input type= 'date' name = 'dateforService' value =".$row['dateforService']."></td>"  ;// this one also 
echo "<td><a href=\"update_request.php?jobrequestnumber={$row['jobrequestnumber']}&requestingcompany={$row['requestingcompany']}&dateforService={$row['dateforService']}\">Update</a></td>";

所以我尝试在以下更新代码之前回显该值： 然后它以正确的日期格式出现。

if (empty($errors)){
$jobrequestnumber = $_GET['jobrequestnumber'];
$requestingcompany = $_GET['requestingcompany'];
$dateforService = date("Y-m-d", strtotime($_GET['dateforService']));
    $query =    "UPDATE jobrequest SET 
                        requestingcompany = '{$requestingcompany}',
                        dateforService = $dateforService 
                    WHERE jobrequestnumber ={$jobrequestnumber}";

非常感谢您的建议，非常感谢。

Answer 1

替换

dateforService = $dateforService 

与

dateforService = '$dateforService'

以防万一

替换

jobrequestnumber ='$jobrequestnumber' // remove { & }. You are not using an array here. And add quotes around it
