[英]How to upload one excel file and display all its rows and columns on the web page via php
我正在編寫用於上傳一個excel文件的代碼。並將其完整內容顯示在網頁上。但是,每當用戶單擊“提交”按鈕時,它都會顯示錯誤-“您的文件類型為:application / vnd.openxmlformats-officedocument.spreadsheetml.sheet文件類型必須為text(.txt)或msword(.doc)。”
下面是我的代碼。
<?php
if( isset($_POST['submit1'])) {
// $_FILES is the array auto filled when you upload a file and submit a form.
$userfile_name = $_FILES['file1']['name']; // file name
$userfile_tmp = $_FILES['file1']['tmp_name']; // actual location
$userfile_size = $_FILES['file1']['size']; // file size
$userfile_type = $_FILES['file1']['type'];
$userfile_error = $_FILES['file1']['error']; // any error!. get from here
// Content uploading.
$file_data = '';
if ( !empty($userfile_tmp))
{
$file_data=base64_encode(@fread(fopen($userfile_tmp,'r'), filesize($userfile_tmp)));
}
switch (true)
{
// Check error if any
case ($userfile_error == UPLOAD_ERR_NO_FILE):
case empty($file_data):
echo 'You must select a document to upload before you can save this page.';
exit;
break;
case ($userfile_error == UPLOAD_ERR_INI_SIZE):
case ($userfile_error == UPLOAD_ERR_FORM_SIZE):
echo 'The document you have attempted to upload is too large.';
break;
case ($userfile_error == UPLOAD_ERR_PARTIAL):
echo 'An error occured while trying to recieve the file. Please try again.';
break;
}
if( !empty($userfile_tmp))
{
// only MS office and text file is accepted.
if( !(($userfile_type=="application/msword") || ($userfile_type=="text/plain") || ($userfile_type=="application/vnd.ms-excel")) )
{echo 'Your File Type is:'. $userfile_type;
echo '<br>File type must be text(.txt) or msword(.doc).';
exit;
}
}
echo filesize($userfile_tmp);
}
?>

請幫忙 。 先感謝您。
您還需要在if條件中添加以下內容,因為您正在檢查application/vnd.ms-excel
和application/msword
但文件的標頭與
"application/vnd.openxmlformats-officedocument.spreadsheetml.sheetyour"
因此,如果您將其添加到內部,例如
if(($userfile_type=="application/vnd.openxmlformats-officedocument.spreadsheetml.sheetyour") || ($userfile_type=="application/msword") || ($userfile_type=="text/plain") ||
($userfile_type=="application/vnd.ms-excel")){
// code
}
因為服務器將根據接收到的標頭解釋文件類型。
如果要在頁面上顯示Excel文件內容,則應考慮使用PHPExcel。 這是非常容易使用。
