我试图找出为什么我的php表单没有将数据从字段输入mySQL数据库。我一直试图解决这个问题,但已经走到了尽头。
我的插入$ sql在使用每个字段的值进行硬编码时工作正常,但在我尝试使用从php表单输入的字段时却没有。
当我点击提交时,我没有收到任何错误,但当我检查mySQL以查看它是否添加了另一个所有者时,没有任何显示。
如果有人可以帮我解决这个问题,我会非常感激。
顺便说一下,我的$ sql insert语句是否正确引号?

将$ _POST值分配给像这样的变量
if (isset($_POST['OwnerNum]))
{
$OwnerNum=$_POST['OwnerNum'];
$LastName=$_POST['LastName'];
$FirstName=$_POST['FirstName'];
$Address=$_POST['Address'];
$City=$_POST['City'];
$State=$_POST['State'];
$Zip=$_POST['Zip'];
try {
$sql = "INSERT INTO Owner (OwnerNum, LastName, FirstName, Address, City, State, Zip) VALUES
('".$OwnerNum."', '".$LastName."', '".$FirstName."', '".$Address."', '".$City."', '".$State."', '".$Zip."')";
$conn->exec($sql);
$select_owner = "SELECT * FROM Owner";
?>
<table>
<tr>
<td>OwnerNum</td>
<td>FirstName</td>
<td>LastName</td>
<td>Address</td>
<td>City</td>
</tr>
<?php
$conn->prepare($select_owner );
$result = $conn->fetchAll();
if (count($result)) {
foreach($result as $owner){
?>
<tr>
<td><?=$owner['OwnerNum'];?></td>
<td><?=$owner['FirstName'];?></td>
<td><?=$owner['LastName'];?></td>
<td><?=$owner['Address'];?></td>
<td><?=$owner['City'];?></td>
</tr>
<?php
}
}
else
{
?>
<tr>
<td colspan="5">No Onwers Found</td>
</tr>
<?php
}
unset($result);
unset($select_owner);
unset($conn);
}
catch (PDOException $e)
{
echo 'Error: '.$e->getMessage();
} //end catch
}

代码对我来说很好,但是在插入数据时,您应首先捕获表单数据,然后将它们存储在变量中。然后在插入查询中使用这些变量。
if (isset($_POST['submit1']))//set your submit btn name to submit1
{
$username=$_POST['OwnerNum'];//likewise catch all data
try {
$sql = "INSERT INTO Owner (OwnerNum, LastName, FirstName, Address, City, State, Zip) VALUES
(?,?,?.....)";//put the placeholders here.the num of placeholders should be equal to number of bound values
