從下面的代碼我可以刪除我的上傳文件夾圖像。但它不會從圖像表中刪除相關記錄。如何完成?我上傳的圖像保存在upload/3子文件夾中。如何刪除上傳的圖像加上圖像表記錄
<form method="post" action="delimagehandler.php">
<center>
<input type="submit" value="Delete" name="Delete" >
</center>
<?php
//lets assign the folder name in $title
//You can assign any name
$title= "upload";
/*$directory corresponds to whole path. Edit to your preference. (i assume u store your
images in directory named "images") */
$directory = "$title/3";
//The array specifies the format of the files
$allowed_types=array('jpg','jpeg','gif','png');
$file_parts=array();
$ext='';
$title='';
$i=0;
$dir_handle = @opendir($directory) or die("There is an error with your image directory!");
while ($file = readdir($dir_handle))
{
if($file=='.' || $file == '..') continue;
$file_parts = explode('.',$file);
$ext = strtolower(array_pop($file_parts));
$title = implode('.',$file_parts);
$title = htmlspecialchars($title);
$nomargin='';
if(in_array($ext,$allowed_types))
{
if(($i+1)%4==0)
$nomargin='nomargin';
echo'
<div id="picture">
<img src="'.$directory.'/'.$file.'" width="150" height="150"><br>
Select <input type="checkbox" value="'.$directory.'/'.$file.'" name="imgfile[]">
</div>';
echo $file;
}
$i++;
}
closedir($dir_handle);
//Now we have the list of images within form elements
?>
</form>
這裏是delimagehandler.php文件
<?php
$file = $_REQUEST['imgfile'];
$num_files=count($file);
for($i=0;$i<$num_files;$i++)
{
unlink ("$file[$i]");
}
echo "Images successfully deleted.Go <a href='delimage.php'>back</a>";
include("connect.php");
if(isset($_POST['Delete'])){
if(isset($_POST['check'])){
foreach ($_POST['check'] as $value){
$sql = "DELETE FROM images WHERE filename = $value";
echo " succsfully DELETED Promo ID.$value";
echo("<BR>");
mysql_query($sql) or die (mysql_error());
}
}
}
?>
是你得到任何錯誤? –
我已經把一個echo $文件;在第一個文件中。它顯示相關的圖像名稱。那麼是否有任何方法將該文件傳遞給第2頁?然後我可以刪除該值的記錄。 – din
