I'm trying to send variables data using ajax but I don't know what will be the property of data:
in $.ajax
I don't know if I'm using it right and heres how I declared my variable:
var value1 = 'value1';
var value2 = 'value2';
var value3 = 'value3';
How do I apply it on the ajax
function?
$.ajax({
url: "insert.php",
method: "post",
data:{value1:value1, value2:value2, value2:value2},
dataType:"text",
success:function(data){
alert('Successfully')
}
});
And here is how I try fetching this data from my insert.php
:
$value1 = mysqli_real_escape_string($con,$_POST['value1']);
$value2 = mysqli_real_escape_string($con,$_POST['value2']);
$value3 = mysqli_real_escape_string($con,$_POST['value3']);
you create datastring like this
var dataString = 'value1='+ value1+ '&value2='+ value2;
$.ajax({
url: "insert.php",
method: "POST",
data:dataString ,
dataType:"text",
success:function(data){
alert('Successfully')
}
});
your code have problem in this line
data:{value1:value1, value2:value2, value2:value2},
you send value2 two time so update this
data: {value1: 'value1', value2: 'value2', value3: 'value3'},
check this code . it will work and you can test this also
this is html code
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function () {
$("#category").change(function () {
var value1 = 'value1';
$.ajax({
type: 'post',
url: 'edit.php',
data: {value1: 'value1', value2: 'value2', value3: 'value3'},
datatype: 'json',
success: function (data) {
alert(data);
}
})
})
})
</script>
<title></title>
</head>
<body>
<form method="post">
<table>
<tr>
<td>category:</td>
<td>
<select id="category">
<option>Select Category</option>
<option value="mobile">Mobile</option>
<option value="TV">Tv</option>
<option value="Phone">Phone</option>
</select>
</td>
</tr>
</table>
</form>
</body>
</html>
then this is insert.php. i write this code for your test purpose
<?php
print_r($_POST);
echo $value1 = $_POST['value1'];
echo "<br>";
echo $value2 = $_POST['value2'];
echo "<br>";
echo $value3 = $_POST['value3'];
