Ajax request posting - php

Question

I apologize for my bad english :)
I'm doing php file with ajax request. json response comes in the format of. but in some cases can be redirect. In this case I want the redirect of the page.
Could you please help me. Thank's.
Example PHP File :
<?php
$status = $_POST['status'];
if($status == 'a'){
// return json response
}else{
echo "<form action='http://www.url.com'>..</form><script type='text/javascript'>form.submit();</script>";
}
?>
Example JS File :
$.ajax({
type: "POST",
url: 'http://www.my_php_file.com'
});

Answer 1

Use success function https://api.jquery.com/jQuery.ajax/
$.ajax({
type: "POST",
url: 'http://www.my_php_file.com'
data: { status : statusVar },
success: function(response){
if (response.status == 'a'){
$( "#results" ).append( response);
}else{
window.location = 'http://www.url.com'
}
});
});

Answer 2

Try this.
url: "http://www.my_php_file.com",
success: function(data) {
document.location.href='YouNewPage.php';
}

You need to detect if the response data is valid JSON:
$.ajax({
type: "POST",
url: 'http://www.my_php_file.com',
success: checkAJAX
});
function checkAJAX(data)
{
var response = $.parseJSON(data);
if(typeof response === "object")
{
}
else
{
// If the AJAX response is not JSON, append the HTML to the document
$('body').append(data);
}
}

Answer 4

Return the html that you want to echo as JSON also:
if($status == 'a'){
// return json response
} else {
echo json_encode(array("redirect" => "<form action='http://www.url.com'>..</form><script type='text/javascript'>form.submit();</script>"));
}
And check redirect in the ajax response:
$.ajax({
type: "POST",
dataType: "json",
url: 'http://www.my_php_file.com',
success: function(data) {
if(typeof data.redirect !== "undefined") {
$("body").append(data.redirect);
}
}
});
Just two reminders, there will be no redirection if request fails( no fail callback) and I assume your casual JSON response doesn't have an attribute redirect.
