PHP文件，而不是附加statment

Question

我有一個代碼

if(count($_FILES) > 0) { 
    foreach($_FILES['fileAttach']['error'] as $status){ 
     if($status === UPLOAD_ERR_OK) { 
     $fname[] = $_FILES['fileAttach']['name'][$Ccount]; 
     $tmp_path[] = $_FILES['fileAttach']['tmp_name'][$Ccount]; 
     $ftype[] = $_FILES['fileAttach']['type'][$Ccount]; 
     } 
     $Ccount++; 
    } 
} else { $fname[] = "0"; $tmp_path[] = "0"; $ftype[] = "0"; } // this not working 

然後我想在功能

SendEmails($ReCEmail,$strSubject,$strMessage,$txtFormName,$txtFormEmail,$fname,$ftype,$tmp_path); 

它的工作原理，直到文件安裝到使用變量，但如果沒有我得到錯誤Notice: Undefined variable: fname in ... on line ..

function SendEmails($vasia,$strSubject,$strMessage,$txtFormName,$txtFormEmail,$fname,$ftypes,$tmp_path) { 

if(count($fname) == 0) 
     { code without variables $fname,$ftypes,$tmp_path } 
else {code with variables $fname,$ftypes,$tmp_path} 
} 

如何解決這個問題？

Answer 1

if(count(array_filter($_FILES['fileAttach']['name'])) > 0) { 
    foreach($_FILES['fileAttach']['error'] as $key => $status){ 
     if($status === 0) { 
     $fname[] = $_FILES['fileAttach']['name'][$key]; 
     $tmp_path[] = $_FILES['fileAttach']['tmp_name'][$key]; 
     $ftype[] = $_FILES['fileAttach']['type'][$key]; 
     } 
    } 
} else { $fname[] = "0"; $tmp_path[] = "0"; $ftype[] = "0"; } 

，並在你的函數變化

if(count(array_filter($fname)) == 0) 

Answer 2

初始化您的$ FNAME數組，如果前：

$fname = array(); 
if($status === UPLOAD_ERR_OK) { 

確認您的上傳過程是通過把與工作呼應後，如果：

if($status === UPLOAD_ERR_OK) { 
     echo "Upload Status: " . $status . "<br>"; 
     $fname[] = $_FILES['fileAttach']['name'][$Ccount]; 

如果回波輸出顯示$狀態！= UPLOAD_ERR_OK，那麼$ fname沒有被初始化，因此Undefined變量錯誤。

如果上傳失敗，請爲該問題創建另一個包含相應代碼片段的問題。

如果所有$ _FILES都是錯誤，那麼文件數組將爲零。所以這個錯誤是印刷

$fname[] = array(); 
$tmp_path[] = array(); 
$ftype[] = array(); 

    foreach($_FILES['fileAttach']['error'] as $key => $status){ 
     if($status === 0) { 
     $fname[] = $_FILES['fileAttach']['name'][$key]; 
     $tmp_path[] = $_FILES['fileAttach']['tmp_name'][$key]; 
     $ftype[] = $_FILES['fileAttach']['type'][$key]; 
     } 
    } 

     if(count($fname)==0) 
    { $fname[] = "0";$tmp_path[] = "0"; $ftype[] = "0"; }
