我想使用"选择文件"按钮上传.txt文件，然后上传.txt文件将保存到另一个目录中。单击"保存"按钮后。场景。
folder/source/tbl_household.txt,tbl_member.txt
将被复制到：
folder/target/tbl.household.txt,tbl_member.txt
我该怎么办？我是php，html，css，javascript的新手。这是我的代码....

和我的上传.php部分
<?php
// A list of permitted file extensions
$allowed = array('png', 'jpg', 'gif','zip');
if(isset($_FILES['upl']) && $_FILES['upl']['error'] == 0){
$extension = pathinfo($_FILES['upl']['name'], PATHINFO_EXTENSION);
if(!in_array(strtolower($extension), $allowed)){
echo '{"status":"error"}';
exit;
}
if(move_uploaded_file($_FILES['upl']['tmp_name'], 'uploads/'.$_FILES['upl'] ['name'])){
echo '{"status":"success"}';
exit;
}
}
echo '{"status":"error"}';
exit;
不好意思。这是我的脚本.js
$(function(){
var ul = $('#upload ul');
$('#drop a').click(function(){
// Simulate a click on the file input button
// to show the file browser dialog
$(this).parent().find('input').click();
});
// Initialize the jQuery File Upload plugin
$('#upload').fileupload({
// This element will accept file drag/drop uploading
dropZone: $('#drop'),
// This function is called when a file is added to the queue;
// either via the browse button, or via drag/drop:
add: function (e, data) {
var tpl = $('<li class="working"><input type="text" value="0" data- width="48" data-height="48"'+
' data-fgColor="#0788a5" data-readOnly="1" data-bgColor="#3e4043" /><p></p> <span></span></li>');
// Append the file name and file size
tpl.find('p').text(data.files[0].name).append('<i>' + formatFileSize(data.files[0].size) + '</i>');
// Add the HTML to the UL element
data.context = tpl.appendTo(ul);
// Initialize the knob plugin
tpl.find('input').knob();
// Listen for clicks on the cancel icon
tpl.find('span').click(function(){
if(tpl.hasClass('working')){
jqXHR.abort();
}
tpl.fadeOut(function(){
tpl.remove();
});
});
// Automatically upload the file once it is added to the queue
var jqXHR = data.submit();
},
progress: function(e, data){
// Calculate the completion percentage of the upload
var progress = parseInt(data.loaded / data.total * 100, 10);
// Update the hidden input field and trigger a change
// so that the jQuery knob plugin knows to update the dial
data.context.find('input').val(progress).change();
if(progress == 100){
data.context.removeClass('working');
}
},
fail:function(e, data){
// Something has gone wrong!
data.context.addClass('error');
}
});
// Prevent the default action when a file is dropped on the window
$(document).on('drop dragover', function (e) {
e.preventDefault();
});
// Helper function that formats the file sizes
function formatFileSize(bytes) {
if (typeof bytes !== 'number') {
return '';
}
if (bytes >= 1000000000) {
return (bytes / 1000000000).toFixed(2) + ' GB';
}
if (bytes >= 1000000) {
return (bytes / 1000000).toFixed(2) + ' MB';
}
return (bytes / 1000).toFixed(2) + ' KB';
}
});
添加'txt'扩展：
$allowed = array('png', 'jpg', 'gif','zip','txt');
并移除按钮：
<button type="button" align ="center" name="save" value="save" >SAVE</button>
并添加此行：
<input type="submit" value="save" />
