本帖最後由 CSA41200 於 2013-10-31 11:14 編輯
各位ching，請問可以點改個code，係每次refresh之後，唔會再出現"XXX uploaded successfully"
code 如下:
<?php
if($_POST['pgaction']=="upload")
upload();
else
uploadForm();
//The form having dynamic file uploader
function uploadForm() {
?>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title> :: FILEUPLOAD :: </title>
<link href="style.css" rel="stylesheet" type="text/css" />
</head>
<body bgcolor="#C8C8C8" leftmargin="0" topmargin="0" rightmargin="0" bottommargin="0">
<br>
<form name="frm" method="post" onsubmit="return validate(this);" enctype="multipart/form-data">
<input type="hidden" name="pgaction">
<?php if ($GLOBALS['msg']) { echo '<center><span class="err">'.$GLOBALS['msg'].'</span></center>'; }?>
<table align="center" cellpadding="4" cellspacing="0" bgcolor="#EDEDED">
<tr class="tblSubHead">
<td colspan="2">Upload any number of file</td>
</tr>
<tr class="txt">
<td valign="top"><div id="dvFile"><input type="file" name="item_file[]"></div></td>
<td valign="top"><a href="javascript:_add_more();" title="Add more"><img src="plus_icon.gif" border="0"></a></td>
</tr>
<tr>
<td align="center" colspan="2"><input type="submit" value="Upload File"></td>
</tr>
</table>
</form>
<script language="javascript">
<!--
function _add_more() {
var txt = "<br><input type=\"file\" name=\"item_file[]\">";
document.getElementById("dvFile").innerHTML += txt;
}
function validate(f){
var chkFlg = false;
for(var i=0; i < f.length; i++) {
if(f.elements.type=="file" && f.elements.value != "") {
chkFlg = true;
}
}
if(!chkFlg) {
alert('Please browse/choose at least one file');
return false;
}
f.pgaction.value='upload';
return true;
}
//-->
</script>
</body>
</html>
<?php
}
//function to store uploaded file
function upload(){
if(count($_FILES["item_file"]['name'])>0) { //check if any file uploaded
$GLOBALS['msg'] = ""; //initiate the global message
for($j=0; $j < count($_FILES["item_file"]['name']); $j++) { //loop the uploaded file array
$filen = $_FILES["item_file"]['name']["$j"]; //file name
$path = 'webupload/'.$filen; //generate the destination path
if(move_uploaded_file($_FILES["item_file"]['tmp_name']["$j"],$path)) { //upload the file
$GLOBALS['msg'] .= "File# ".($j+1)." ($filen) uploaded successfully<br>"; //Success message
}
}
}
else {
$GLOBALS['msg'] = "No files found to upload"; //Failed message
}
uploadForm(); //display the main form
}
?>

你show完msg 唔清番佢 咁你upload完一次之後佢永遠都係度 咪每次都會彈success message 最簡單試試
<?php if ($GLOBALS['msg']) { echo '<center><span class="err">'.$GLOBALS['msg'].'</span></center>'; unset($GLOBALS['msg']);}?>

可能係if statment condition 問題，因(而家$GLOBALS['msg']係true就會show msg?) 而唔係check佢係咪空既，
一係就
<?php if (isset($GLOBALS['msg'])) { echo '<center><span class="err">'.$GLOBALS['msg'].'</span></center>'; unset($GLOBALS['msg']);}?>
一係就
<?php if ($GLOBALS['msg'] != "") { echo '<center><span class="err">'.$GLOBALS['msg'].'</span></center>'; $GLOBALS['msg'] = "";}?>

educationer ching，跟你ge做法都係唔得 >.<
1. 起初係咁ge
[attach]1600390[/attach]
2. 成功upload係咁ge
[attach]1600391[/attach]
3. 按F5 refresh
[attach]1600394[/attach]
4. 之後就變成咁
[attach]1600395[/attach]
已經無野upload，按F5 refresh，竟然"XXX 成功upload"句野仲係返度 >.<

你撳重試果陣等於resubmit左張form，所以有message係正常。

ching，咁可以點搞？

refresh 就自然會將個post做多次, 呢件係好合理既事
如果真係要避, 可以格硬係upload success 做個 header redirect 之類等browser refresh唔再submit

如果你 submit 過張 form，refresh browser 撳確定會叫個 browser 將你頭先尐野重新 submit 一次，所以有 successful message，係無錯架喎...

呢個係browser behaviour，唔關PHP事。如果你真係好唔想人地submit完refresh會重新submit，可以做個server side redirect去返同一頁.

試下submit完用header redirect啦
一係加個session黎check住佢
作者: justlazy 時間: 2013-11-7 02:53
- <?php header('Location: <url>'); ?>
