Up to this moment I was using this types of methods to send some variables via Ajax to server side php file and bring back some answer.
$('#some_form').ajaxSubmit({
success: function(result)
{
some code....
}
});开发者_StackOverflow社区
$.post('serverside_script.php', { variable: 'value' },
function(result)
{
some code...
});
Answer was always in 1 variable and it was ok till now. But now I need several variables to come back from PHP side. How can I modify my scripts to get several variables back ?
The "result" in the callback you have showed is all that you could get from PHP - this is the server side response. You could retun JSON from PHP - something like this:
$json = json_encode(array('content' => 'some html content to show on page', 'var2' => 'value2', 'var3' => 'value3'));
echo $json;
exit;
Probably you will then need to parse the JSON: http://api.jquery.com/jQuery.parseJSON/
$.post('serverside_script.php', { variable: 'value' }, function(result)
{
result = jQuery.parseJSON(result);
alert(result.content);
alert(result.var2);
alert(result.var3);
});
