jQuery Question
Use jQuery to post data to php file
I am making a search engine.I want to post the data from jquery to php.
Here is my code of jQuery
<script>
$(document).keypress(function(e) {
if(e.which == 13 && $('#textfield').val()) {
$.post("search_result.php",
{
wording: $('#textfield').val()
}, function() {
window.location = "search_result.php";
}
);
}
});
</script>
Here is my code of php to get the wording:
<?php include('../include/common_top.php');
$key_word = $_POST["wording"];
var_dump($key_word);
?>
But what I get is a null value.Please help.

You shouldn't redirect to the PHP script. That runs it a second time, but this time with no POST parameters.
The output of the PHP script from the AJAX request will be the argument to the callback function, you can display it from there.
$(document).keypress(function(e) {
if(e.which == 13 && $('#textfield').val()) {
$.post("search_result.php",
{
wording: $('#textfield').val()
}, function(result) {
$("#somediv").text(result);
}
);
}
})
