Question

我创建了一个画廊管理。我用While循环打印了图像缩略图。我可以通过复选框选择要删除的照片，然后提交表单。当我发送表单时，页面刷新，她运行图像unlink（），删除行查询，但我仍然看到图像的打印行404（未找到）。如果我刷新另一个，那就行了！

代码：

<form name="form" method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">

//while loop

</form>

<?php


if (isset($_POST['delete'])) {


    $delete = $_POST['select'];

foreach ($delete as $id => $val) {

    $query="SELECT foto FROM gallery WHERE id = '$val'";
    $result1= mysql_query($query);
     while($row = mysql_fetch_assoc($result1)) {
        unlink($output_dir . $row[foto]); 
    }

    $query="DELETE FROM gallery WHERE id = '$val'";
    $result2= mysql_query($query) or die (mysql_error()); 



}



}

解决。编辑：

if (isset($_POST['delete'])) {


    $delete = $_POST['select'];

foreach ($delete as $id => $val) {

    $query="SELECT foto FROM gallery WHERE id = '$val'";
    $result1= mysql_query($query);
     while($row = mysql_fetch_assoc($result1)) {
        unlink($output_dir . $row[foto]); 
    }

    $query="DELETE FROM gallery WHERE id = '$val'";
    $result2= mysql_query($query) or die (mysql_error()); 



}



}

 <form name="form" method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">

    //while loop

    </form>

Answer 1

你必须在php代码之后编写表单

Answer 2

您应该在HTML部分之前运行PHP代码。

试试这个：

<?php
if (isset($_POST['delete'])) {
  $delete = $_POST['select'];
  foreach ($delete as $id => $val) {
    $query="SELECT foto FROM gallery WHERE id = '$val'";
    $result1= mysql_query($query);
    while($row = mysql_fetch_assoc($result1)) {
      unlink($output_dir . $row[foto]); 
    }

    $query="DELETE FROM gallery WHERE id = '$val'";
    $result2= mysql_query($query) or die (mysql_error()); 
  }
}
?>

<form name="form" method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
  //while loop
</form>

提交表单后刷新页面
