Question

我正在尝试删除文件夹内的文件，使用delete_file.php，这是动作文件offcourse。它只能将数据接收为$_POST['filename1']，但对于每次foreach()次迭代，此值都会被覆盖。任何建议，还有什么可以解决这个问题？在此先感谢。

问题：
delete_file.php将filename1作为$_POST['filename1']捕获但是每次foreach迭代，filename1都会被覆盖。并且delete_file.php仅在每次都删除最后一次。

Answer 1

您可以尝试删除php循环：

<script type = "text/javascript" >
$(function() {
   $('div[id^="modaltrigger_"]').leanModal({
    top: 200,
    overlay: 0.6,
    closeButton: ".modal_close"
  });
  $('div[id^="modaltrigger_"]').click(function() {
    magica = $(this).attr('id').split('_')[1];
    $('.deleteplogo_' + magica).show();
    return false;
  });

})


$('div[id^="ajax-submit_"]').click(function() {
  magica = $(this).attr('id').split('_')[1];
  var filename = $("#filename_" + magica).val();
  if (filename == '') {
    alert("File doesn't EXIST....!!");
  } else {

    $.post("delete_file.php", {
      filename1: filename
    }, function(data) {
      $("span.modal_close > i").trigger("click");
      //alert(data).fadeOut("slow"); damn you can't fade out a alert box :))
      window.location = mypage.php;


  } // else ends here
 });
}); < /script>

更好的解决方案是用类替换id并将数据属性附加到magica

的值的元素上

Answer 2

删除了所有AJAX-JQUERY代码＆amp;使用：

file1.php

    <td>
    <p style="text-align: center; font-size: 10px; margin-top: 5px;">
    <a id="modaltrigger_<?= $variable_id ?>" href="delete.php?id=<?php echo $imageName; ?>" class="btn"
    style="border: none !important;">Delete</a>
    </p>
    </td>

delete.php

    <?php

    $filePath = "D:/folder/".$_GET['id'];
    if(is_file($filePath)){
    @unlink($filePath);
    echo ('<strong>SUCCESS! Deleted: &nbsp; <span style="color:red">'. $_GET['id']. '</span>,&nbsp; file from Directory</strong>');
    }
    else if(!unlink($filePath)){ 
    echo ("Error deleting file : ". $_GET['id']. " Already deleted OR doesn't EXIST"); 
    }

    ?>

像魅力一样工作！谢谢！

使用jquery- $ .post（）;在php- foreach（）函数内部，将变量数据发送到URL文件
