Question

随机发生。我注意到它经常在第二次或第三次尝试后失败。使用$ _REQUEST似乎也不起作用。这是我的表格 -

<form method="post" action='updateImage' enctype="multipart/form-data">
<input type="hidden" name="uname" value="user">
<input type="hidden" name="image" value="photograph">
<label data-toggle="tooltip" data-placement="bottom" title="Click here to select an image">
<input type="file" name="file" accept="image/*" class="input" onchange="preview()" style="display: none;" required/>
</label>
<input type="submit" name="submit_student_photograph" value="Update Student Photograph">
</form>

编辑1：这是php脚本 -

$foldername = $this->student()->setStudentData($_POST)->setFoldername();
  $filename = $foldername.'_photograph_1';
  $handle = new upload($_FILES['file']);
  if ($handle->uploaded) {
    $handle->file_new_name_body   = $filename;
    $handle->image_resize         = true;
    $handle->image_x              = 600;
    $handle->image_ratio_y        = true;
    $handle->process('all_student_files/'.$foldername);
    if ($handle->processed) {
      $handle->clean();
      $_SESSION['success'] = "Image has been updated.";
      header("Location:?controller=students&action=showStudentProfile&uname=".$_POST['uname']."#".$_POST['direction']);
    } else {
      $_SESSION['error'] = "There was a problem updating the Image. Please try again!";
      header("Location:?controller=students&action=showStudentProfile&uname=".$_POST['uname']."#".$_POST['direction']);
    }
  }

好的，我找到了这个问题的原因！ PHP设置不接受任何超过2 MB大小的文件，因此我的脚本执行失败。

表单有时无法将$ _POST数据发送到PHP脚本
