我的代码有问题。我无法更新我的图像。
这是我的完整代码:
索引.php
//this link will post my data to next page
<a href="updatepage.php?code=<?php echo $row['name']; ?>">update</a>
更新页面.php
//this page will get all data that want to update...
<?php
include("config.php");
$name=$_GET['code'];
$sql1 = "select * from imagename where name='$name'";
$result = mysql_query($sql1) or die(mysql_error());
$row=mysql_fetch_array($result);?>
<form name="form1" method="post" action="processupdatepage.php" class="formposition" enctype="multipart/form-data" >
<table>
<tr><td>
<input type="hidden" name="id" value="<?php echo $row['id']; ?>" /></td></tr>
<tr><td width="98">Image</td><td width="288">
//This is where I have problem, I can't get my image value but other data value work very well.....
<input type="file" name="image" value="<?php echo $row['image'];?>" /></td></tr><br/>
<tr><td>nane</td><td><input type="text" name="name" value="<?php echo $row['name']; ?>"/></td></tr><br/>
<tr><td></td> <td colspan="2">
<input type="submit" name="submit" value="Save" /> </td></tr>
</table>
</form>
好的。现在这是我的流程文件:
进程更新页面.php
<?php
include("config.php");
$id=$_POST['id'];
$image=$_FILES['image']['name'];
$name=$_POST['name'];
$target = "images/";
$target = $target . basename( $_FILES['image']['name']);
$query = "UPDATE imagename SET name='$name', image='$image' WHERE id='$id'";
$bb = mysql_query($query) or die(mysql_error());
if($bb)
{
//Writes the photo to the server
if(move_uploaded_file($_FILES['image']['tmp_name'], $target))
{
$sql001="UPDATE imagename SET image='$image' WHERE image='$image'";
mysql_query($sql001);
} else { }
header("Location:index.php");
}
else
{
echo "Could not be updated";
}
?>
我可以更新但必须选择图像。如果我没有选择图像,我在数据库中的图像字段将为空,但其他数据更新正常...
