Question

如何通过按CTRL键在单个按钮上单次上传多个图像。我想通过按CTRL键同时点击要上传的文件，在html和php中一次尝试多次上传？ HTML代码：

<table width="500" border="0" align="center" cellpadding="0" cellspacing="1" bgcolor="#CCCCCC">
<tr>
<form action="multiple_upload_ac.php" method="post" enctype="multipart/form-data" name="form1" id="form1">
<td>
<table width="100%" border="0" cellpadding="3" cellspacing="1" bgcolor="#FFFFFF">
<tr>
<td><strong>multiple Files Upload </strong></td>
</tr>
<tr>
<td>Select file
<input name="ufile[]" type="file" id="ufile[]" size="50" multiple="multiple" /></td>
</tr>



<tr>
<td align="center"><input type="submit" name="Submit" value="Upload" /></td>
</tr>
</table>
</td>
</form>
</tr>
</table>

php代码：

$path1= "upload/".$HTTP_POST_FILES['ufile']['name'][0];
    $path2= "upload/".$HTTP_POST_FILES['ufile']['name'][1];
    $path3= "upload/".$HTTP_POST_FILES['ufile']['name'][2];

    copy($HTTP_POST_FILES['ufile']['tmp_name'][0], $path1);
    copy($HTTP_POST_FILES['ufile']['tmp_name'][1], $path2);
    copy($HTTP_POST_FILES['ufile']['tmp_name'][2], $path3);

echo "File Name :".$HTTP_POST_FILES['ufile']['name'][0]."<BR/>";
echo "File Size :".$HTTP_POST_FILES['ufile']['size'][0]."<BR/>";
echo "File Type :".$HTTP_POST_FILES['ufile']['type'][0]."<BR/>";
echo "<img src=\"$path1\" width=\"150\" height=\"150\">";
echo "<P>";

echo "File Name :".$HTTP_POST_FILES['ufile']['name'][1]."<BR/>";
echo "File Size :".$HTTP_POST_FILES['ufile']['size'][1]."<BR/>";
echo "File Type :".$HTTP_POST_FILES['ufile']['type'][1]."<BR/>";
echo "<img src=\"$path2\" width=\"150\" height=\"150\">";
echo "<P>";

echo "File Name :".$HTTP_POST_FILES['ufile']['name'][2]."<BR/>";
echo "File Size :".$HTTP_POST_FILES['ufile']['size'][2]."<BR/>";
echo "File Type :".$HTTP_POST_FILES['ufile']['type'][2]."<BR/>";
echo "<img src=\"$path3\" width=\"150\" height=\"150\">";

$filesize1=$HTTP_POST_FILES['ufile']['size'][0];
$filesize2=$HTTP_POST_FILES['ufile']['size'][1];
$filesize3=$HTTP_POST_FILES['ufile']['size'][2];

if($filesize1 && $filesize2 && $filesize3 != 0)
{
echo "We have recieved your files";
}

else {
echo "ERROR.....";
}

if($filesize1==0) {
echo "There're something error in your first file";
echo "<BR />";
}

if($filesize2==0) {
echo "There're something error in your second file";
echo "<BR />";
}

if($filesize3==0) {
echo "There're something error in your third file";
echo "<BR />";
}

HTML：

<!-- IMPORTANT:  FORM's enctype must be "multipart/form-data" -->
<form method="post" action="upload-page.php" enctype="multipart/form-data">
  <input name="filesToUpload[]" id="filesToUpload" type="file" multiple="" />
</form>

PHP：

if(count($_FILES['uploads']['filesToUpload'])) {
    foreach ($_FILES['uploads']['filesToUpload'] as $file) {

        //do your upload stuff here
        echo $file;

    }
}
