GD - imagecopyresampled：代碼

Question

怪行我有一個表格，其中有一個輸入類型的文件的人的名字是「照片」

的目標是調整該用戶再進數據庫上傳照片。

主要錯誤是，當我點擊提交頁面顯示我噸的怪像這樣的代碼：

����JFIF��m���b~bs�I$��'$V�ڳ�v,HL���rr0{ �r�I4����nCT�����O���%�vw|��;��[쯧��!VOݓI&Ҽ�M춶��o�Z�ѥ��Vb���������� ۧ��b��zi8Pr�%�9 ��猞3!�Dx�,U�8t�F�cМ�X��lP� 

如果我點擊提交我做了以下說明

$fFoto=""; 

if($_FILES['foto']['error'] == UPLOAD_ERR_OK) { 

    $fFile="/upload/inserzionisti/".$id."_".$_FILES["foto"]["name"]; 
    $fFoto=$id."_".$_FILES["foto"]["name"]; 

    $percent = 0.5; 

    list($width,$height) = getimagesize("upload/inserzionisti/".$fFoto.""); 
    $new_width = $width * $percent; 
    $new_height = $height * $percent; 

    $image_p = imagecreatetruecolor($new_width,$new_height); 
    $image = imagecreatefromjpeg("upload/inserzionisti/".$fFoto.""); 

     imagecopyresampled($image_p,$image,0,0,0,0,$new_width,$new_height,$width,$height); 
    imagejpeg($image_p,null,100); 

    move_uploaded_file($_FILES["foto"]["tmp_name"],".".$fFile); 
    $sql = "UPDATE inserzionisti SET FotoUrl ='$fFoto' where Id=$id"; 

待辦事項你有什麼建議嗎？

嘗試此代碼：

$fFoto=""; 

if($_FILES['foto']['error'] == UPLOAD_ERR_OK) { 
    $fFile="/upload/inserzionisti/".$id."_".$_FILES["foto"]["name"]; 
    $fFoto=$id."_".$_FILES["foto"]["name"]; 

    $percent = 0.5; 

    list($width,$height) = getimagesize("upload/inserzionisti/".$fFoto.""); 
    $new_width = $width * $percent; 
    $new_height = $height * $percent; 

    $image_p = imagecreatetruecolor($new_width,$new_height); 
    // create the new image from the uploaded file 
    $image = imagecreatefromjpeg($_FILES["foto"]["tmp_name"]); 

    imagecopyresampled($image_p,$image,0,0,0,0,$new_width,$new_height,$width,$height); 
    // add the new path as second parameter of imagejpeg() to save the file in the specified location 
    imagejpeg($image_p,$fFile,100); 

    // the following line isn't necessary anymore 
    // move_uploaded_file($_FILES["foto"]["tmp_name"],".".$fFile); 
    $sql = "UPDATE inserzionisti SET FotoUrl ='$fFoto' where Id=$id";
