移至Web服務器后無法讀取或上傳php中的文件名

Question

我正在嘗試使用php上傳文件，並且我創建的代碼在我的本地主機上可以正常運行，但是，上傳到Web服務器后，它認為表單上的文件名為空，甚至無法讀取。 這是我創建的代碼。 它將上傳的文件名讀取為空白。 請幫忙。

<form action="registerSchool.php" method="post" enctype="multipart/form-data" name="form1">

                <input type="text" name="schoolName" id="name" placeholder="Name of School" />

                <input type="text" name="schoolAddr" id="Address" placeholder="School Address" />

                <input type="text" name="schooluri" id="uri" placeholder="School Home Page URL" />

                <label for="logo">Upload School logo: </label><input name="logo" type="file" id="logo" />

                <input type="text" name="superAdminUser" id="Admin_username" placeholder="Super Admin UserName" />

                <input type="password" name="superAdminPass" id="Admin_Password" placeholder="Super Admin Password" />

                <input type="password" name="superAdminPass2" placeholder="Enter Password Again" />

您是否有權在服務器上寫？ 可能只是您需要chmod文件夾

我認為你的代碼應該工作
