我在php

标签： php database upload

我有这个表单，它接受文本输入，在它下面你可以上传图像，最多四个（但它是可选的，你可以选择不上传图像）。 然后将文本和图像或图像分配给数据库中当前登录的用户。 然而，我遇到了一个挑战，当我使用所有可用的图像上传输入时，它成功上传并分配给数据库。 但是当我上传少于4个1,2或3时，没有任何反应。请帮助检查下面的代码。

当您检查文件名是否为空时，如果file_name_2为空，那么您将所有文件重命名为＆＃34; ＆＃34;（空）

if (empty($file_name_1) OR empty($file_name_2) or empty($file_name_3) or empty($file_name_4) ) {
    $file_name_1=" " ;
    $file_name_2=" " ;
    $file_name_3=" " ;
    $file_name_4=" " ;
}

您应该单独检查名称是否为空，并仅重命名这些文件名。 

if (empty($file_name_1)) $file_name_1=" " ;
if (empty($file_name_2)) $file_name_2=" " ;
if (empty($file_name_3)) $file_name_3=" " ;
if (empty($file_name_4)) $file_name_4=" " ;

感谢大家，我已经解决了这个问题，为了这里可能有类似问题的人，处理上传的代码就是这样。

   if(isset($_FILES['upload_thread_image1'])){
      $errors= array();
      //for first image
      $file_name_1 = $_FILES['upload_thread_image1']['name'];
      $file_size_1 =$_FILES['upload_thread_image1']['size'];
      $file_tmp_1 =$_FILES['upload_thread_image1']['tmp_name'];
      $file_type_1=$_FILES['upload_thread_image1']['type'];
      $file_explode_1=explode('.',$_FILES['upload_thread_image1']['name']);
      $file_ext_1=strtolower(end( $file_explode_1));




      $current_time=time();
      $expensions= array("jpeg","jpg","png");

      if( 

        (in_array($file_ext_1,$expensions) === false)

       )

      {
         $errors[]="extension not allowed, please choose a JPEG or PNG file.";
      }

      if(
        $file_size_1 > 2000000 

        ){
         $errors[]='File size must not exceed 2 MB';
      }


      if(empty($errors)==true){

      }



      move_uploaded_file($file_tmp_2,"ot_imgs/ot_thread_imgs/".$file_name_2);
 }//End for image 2





 if(isset($_FILES['upload_thread_image3'])){
      $errors= array();

   //for third image
      $file_name_3 = $_FILES['upload_thread_image3']['name'];

       )

      {
         $errors[]="extension not allowed, please choose a JPEG or PNG file.";
      }

      if(
        $file_size_3 > 2000000 

        ){
         $errors[]='File size must not exceed 2 MB';
      }


      if(empty($errors)==true){
        $current_time=time();
        $file_name_3=$current_time.$get_username.$file_name_3;
 }

move_uploaded_file($file_tmp_3,"ot_imgs/ot_thread_imgs/".$file_name_3);

}//End for Image 3


if(isset($_FILES['upload_thread_image4'])){
      $errors= array();

        //for fourth image
      $file_name_4 = $_FILES['upload_thread_image4']['name'];
      $file_size_4 =$_FILES['upload_thread_image4']['size'];
      $file_tmp_4 =$_FILES['upload_thread_image4']['tmp_name'];

$current_time=time();
      $expensions= array("jpeg","jpg","png");

      if( 

        (in_array($file_ext_4,$expensions) === false)

       )

      {
         $errors[]="extension not allowed, please choose a JPEG or PNG file.";
      }

      if(
        $file_size_4 > 2000000 

        ){
         $errors[]='File size must not exceed 2 MB';
      }


      if(empty($errors)==true){
        $current_time=time();
        $file_name_4=$current_time.$get_username.$file_name_4;
       }

move_uploaded_file($file_tmp_4,"ot_imgs/ot_thread_imgs/".$file_name_4);

}//end for image 4

然后我根据需要将每个图像变量输入到数据库中，即$ file_name_1，$ file_name_2 .......
