First off this is my first question on here so I am sorry for anything I may do wrong. But....
My question is how do I take whats sent back from my PHP file to see if username/password combo exists in the database. My PHP either returns true or false depending on the submitting. That works fine I just do not know how to use the returned data and compare it to either true or false.
////This is my Jquery of my form which works fine validating and sending data to PHP.
$("#frmsignin").validate({
rules:{
passin:"required",
emailin:{
required:true,
email:true
}
},
messages:{
passin:"Please enter YOUR password",
emailin:{
required:"Please enter YOUR email address",
email:"Please enter a VALID email address"
}
},
submitHandler: function(form) {
$.post('sign_in.php',
$("#frmsignin").serialize(),
function(data){$('#results').html(data)});
}
});
Right Now I just have my PHP file printing back true/ false just to get the error message or redirection to occur if user signs in correctly.
Simple: Return a json data structure:
<php
$data = '... the stuff you want to return';
if ($data == '') {
// oops something blew up
$json = array('success' => false);
} else {
$json = array('success' => true, $data);
}
echo json_encode($json);
Then in your JS code:
function(data) {
var serverdata = jQuery.parseJSON(data);
if (serverdata.success) {
... it worked
} else {
... something blew up, handle it
}
}
