[英]getting php session from javascript variable
我在我的php网站中使用了一个jQuery日期和时间选择器。 我想将javascript变量另存为php会话,我在此站点上查看了以前的答案并尝试了建议,但它似乎对我不起作用。 谁能告诉我我想念的是什么?
这是我的jquery日期和时间选择器,获取选定的日期和时间以及发布ajax:
<input type="text" name="date2" value="">
<script type="text/javascript">
$(function(){
$('*[name=date2]').appendDtpicker({"inline": true,
"allowWdays": [1, 2, 3, 4, 5], // 0: Sun, 1: Mon, 2: Tue, 3: Wed, 4: Thr, 5: Fri, 6: Sat
"futureOnly": true,
"autodateOnStart": false
});
$('#btn_input').on('click', function(){
var input = $('*[name=date2]').handleDtpicker('getDate');
console.log(input);
jQuery.ajax({
url: 'backend.php',
type: 'POST',
data: {
'input': input,
},
dataType : 'json',
success: function(data, textStatus, xhr) {
console.log(data); // do with data e.g success message
},
error: function(xhr, textStatus, errorThrown) {
console.log(textStatus.reponseText);
}
});
});
});
</script>
<input type="submit" class="btn" id="btn_input" value="Confirm">
这是backend.php,我将其发送至:
<?php
session_start();
$_SESSION['input'] = $_POST['input'];
echo ($_SESSION['input']);
?>
任何帮助深表感谢!
新答案 :
的HTML
<!DOCTYPE html>
<html>
<head>
<!-- include jquery here -->
<script type="text/javascript" src="jquery.simple-dtpicker.js"></script>
<link type="text/css" href="jquery.simple-dtpicker.css" rel="stylesheet"/>
</head>
<body>
<input type="text" class="myDatepicker"/>
</body>
</html>
JS
$(function(){
$('.myDatepicker').appendDtpicker({ //please note that it requires an element that fits this selector
'inline' : true,
'allowWdays' : [1, 2, 3, 4, 5],
'futureOnly' : true,
'autodateOnStart' : false
'onHide': function(handler){
$.ajax({
type: 'POST',
url: 'backend.php',
data: 'input='+ handler.getDate(), //the selected value is being sent to your php, where the session variable is set accordingly
success: function(response){
console.log(response); //in case you have any output (e.g. error messages) in backend.php we will output them to the console for debugging purposes.
}
});
}
});
});
PHP(backend.php)
<?php
session_start();
$_SESSION['input'] = $_POST['input'];
echo $_SESSION['input'];
?>
完整的脚本通常如下所示:
index.php / index.html
<!DOCTYPE html>
<html>
<head>
<!-- include jquery here -->
</head>
<body>
<input type="text" class="myDatepicker"/>
</body>
</html>
<script type="text/javascript">
$(function(){
$('.myDatepicker').appendDtpicker({ //please note that it requires an element that fits this selector
'inline' : true,
'allowWdays' : [1, 2, 3, 4, 5],
'futureOnly' : true,
'autodateOnStart' : false
'onHide': function(handler){
$.ajax({
type: 'POST',
url: 'backend.php',
data: 'input='+ handler.getDate(), //the selected value is being sent to your php, where the session variable is set accordingly
success: function(response){
console.log(response); //in case you have any output (e.g. error messages) in backend.php we will output them to the console for debugging purposes.
}
});
}
});
});
</script>
请注意,backend.php的路径建议index.php / index.html和backend.php位于同一文件夹中。
原始答案 :最初我以为我们在谈论jQuery-ui datepicker。 如果有人需要,我将保留此回复。
这是这样做的一种方式...
$('.myElement').datepicker({
minDate: 0, //dates from today and onwards
onSelect: function(date){ //"date" will have the selected value of the datepicker
$.ajax({
type: 'POST',
url: 'backend.php',
data: 'input='+ date, //the selected value is being sent to your php, where the session variable is set accordingly
success: function(response){
console.log(response); //in case you have any output (e.g. error messages) in backend.php we will output them to the console for debugging purposes.
}
});
});
因此,您也应该使用jquery cookie( Jquery Cookies )..因此,调用ajax成功后,您将通过传递backend.php获得返回会话,然后将结果存储到jquery cookie中。 之后,您可以使用cookie进行下一步。
尝试:
<script>
jQuery(function($) {
$(document).on('click', '#btn_input', function(){ // edit here
var input = $('*[name=date2]').handleDtpicker('getDate');
console.log(input);
jQuery.ajax({
url: 'backend.php',
type: 'POST',
data: {
'input': input,
},
dataType : 'json',
success: function(data, textStatus, xhr) {
console.log(data); // do with data e.g success message
},
error: function(xhr, textStatus, errorThrown) {
console.log(textStatus.reponseText);
}
});
});
});
</script>
这样行吗? 如果不是,那么控制台中input
的值是多少?
