[英]passing data to php using ajax
this is not my first time to use ajax on my website but right now im really confused whats wrong with it. 这不是我第一次在我的网站上使用Ajax,但现在我真的很困惑它的问题所在。 i even removed the important codes.
我什至删除了重要的代码。 what im doing right now.
我现在在做什么。 is to check if ajax is passing the data to the php or not.
是要检查ajax是否将数据传递给php。
<script type='text/javascript'>
$(document).ready(function () {
$('.btndeclineme').click(function () {
var docreason = document.getElementById("docreason");
if (docreason !== null && docreason.value === "")
{
$('#reasonalert').show();
return;
}else{
var signatoryidglobal = JSON.parse('<?php echo json_encode($_SESSION['signatoryid']); ?>');
alert(signatoryidglobal);
$('#reasonalert').hide();
$.ajax({
type: "POST",
url: "sample.php",
data: ({dtsignatory: signatoryidglobal})
})
.done(function (msg) {
alert( "Data:" + msg);
})
.fail(function() {
alert( "Posting failed." );
});
};
});
});
</script>
and this is the sample.php 这是sample.php
<?php
$temp1 = $_POST['dtsignatory'];
echo $temp1;
?>
my problem is its not showing errors. 我的问题是它没有显示错误。 isn't it supposed to promp the data i passed to the php because of alert( "Data:" + msg);
是不是因为alert(“ Data:” + msg)来提示我传递给php的数据? but it keeps showing nothing.
但它一直不显示任何内容。
i even add a alert prompt to check if the variable has a value. 我什至添加了警报提示,以检查变量是否具有值。 and it has a value.
它具有价值。 sorry for my bad english.
对不起,我的英语不好。 i hope my question is clear
我希望我的问题清楚
$.ajax({
type: "POST",
url: "sample.php",
data: {
dtsignatory: signatoryidglobal
},
headers: {
"Accept": "application/json; charset=utf-8"
},
contentType: "application/json; charset=utf-8",
})
