我的php文件上传代码是这样的

if(isset($_REQUEST['submit']))
        {
          $category_nm = isset($_POST['category_nm']) ?  $_POST['category_nm'] : '';
          $cat_img     = isset($_POST['cat_img']) ?  $_POST['cat_img'] : '';

          $insertCat = "INSERT INTO category(category_nm,cat_img) 
                                 VALUES('".mysql_real_escape_string ($category_nm)."',
                                          '".mysql_real_escape_string ($cat_img)."')";
        $insertCatRes = mysql_query($insertCat);
        if($insertCatRes)
        {
          $target_dir = "_cat_img/";
          $target_file = $target_dir . basename($_FILES["cat_img"]["name"]);
          $uploadOk = 1;
          $imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
          // Check if image file is a actual image or fake image
          if(isset($_POST["submit"])) 
          {
            $check = getimagesize($_FILES["cat_img"]["tmp_name"]);
            if($check !== false) 
            {
              echo "File is an image - " . $check["mime"] . ".";
              $uploadOk = 1;
            } 
            else
            {
              echo "File is not an image.";
              $uploadOk = 0;
            }
          }

          // Check file size
          if ($_FILES["cat_img"]["size"] > 500000)
          {
            echo "Sorry, your file is too large.";
            $uploadOk = 0;
          }
          // Allow certain file formats
          if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg"
            && $imageFileType != "gif" ) 
          {
            echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
            $uploadOk = 0;
          }
            // Check if $uploadOk is set to 0 by an error
          if ($uploadOk == 0) 
          {
            echo "Sorry, your file was not uploaded.";
            // if everything is ok, try to upload file
          }
          else 
          {
            if (move_uploaded_file($_FILES["cat_img"]["tmp_name"], $target_file)) 
            {
              echo "The file ". basename( $_FILES["cat_img"]["name"]). " has been uploaded.";
            }
            else
            {
              echo "Sorry, there was an error uploading your file.";
            }
          }
        }
        else
        {
           //header("Location:category.php");   
        }

      }

文件的发布时间$_FILES不是$_POST。

更改

$cat_img = isset($_POST['cat_img']) ? $_POST['cat_img']: '';

要

$cat_img = isset($_FILES['cat_img']['name']) ? $_FILES['cat_img']['name'] : '';

图像上传名称未插入数据库
