Question

我在将图像路径上传到数据库时遇到问题。数据库调用：basketball_database和表调用：media，columns：id（int，auto increment），name（varchar），image（varchar）

我尝试从计算机上的不同目录上传的所有图像都是png文件。出于某种原因，我只能上传1个图像，数据库不显示图像名称或图像路径。任何人都可以帮我解决这些问题吗？谢谢

文件1：upload_image.php

<html>
    <body>
    <form action="uploaded_file.php" method="post"
    enctype="multipart/form-data">
    <label for="file">Filename:</label>
    <input type="file" name="file" id="file"><br>
    <input type="submit" name="submit" value="Submit">
    </form>
    </body>
    </html>

文件2：upload_file.php

 mysql_select_db("$database")
 or die("Could not select Basketball_database");
 //echo "Connected to database";

//image extensions allowed
$allowedExts = array("gif", "jpeg", "jpg", "png");
$temp = explode(".", $_FILES["file"]["name"]);
$extension = end($temp);

  {
  if ($_FILES["file"]["error"] > 0)

    echo "Return Code: " . $_FILES["file"]["error"] . "<br>";
    }
  else

    echo "Type: " . $_FILES["file"]["type"] . "<br>";
    echo "Size: " . ($_FILES["file"]["size"] / 1024) . " kB<br>";

    //Display Image
    echo "<img src=uploaded/" . $_FILES["file"]["name"] . ">";

    //Uploaded image folder
    if (file_exists("uploaded/" . $_FILES["file"]["name"]))
      {
      echo $_FILES["file"]["name"] . " already exists. ";
      }
    else
      {
      move_uploaded_file($_FILES["file"]["tmp_name"],
      "uploaded/" . $_FILES["file"]["name"]);

      }
    }
  }
else
  {
    //error message on the extension that are not allowed
    echo "Invalid file"; 
    $filename = preg_replace('/[^A-Z0-9]/','',$_FILES["file"]["name"]) . $extension;
    $logo = uploaded/$filename; 

    //insert into database
        $strSQL = "INSERT INTO $table(name,image) VALUES('$name_file','$logo')";
    mysql_query($strSQL) or die(mysql_error());
  }
?>
