Question

I have quite some experience with php, but I am very new to using jQuery.

I am hoping someone can give me some example code (preferably) or point me in the right direction for which jQuery functions I need to use, essentially, what I want to do is for a user to submit a form in php and then for the results of that form submit to be displayed on the same page using jQuery (I assume).

Like I said I have very little experience with jQuery, and none doing something like this. So any help is appreciated.

Well, this answer is not really targeted at the newbie, but if you really want to dig into writing your own custom a PHP/JQuery interface you might want to try something like this:

• use ajax function name as a php pseudo function name
• implement jquery and let php echo the output.
• this can be useful if you want to only write your code in php only
• not really practical but it works some 90% of the time.

Note sure if there’s any library out there that does this implementation but I do have some
sample implementation which I use on some custom development projects, maybe you might find
some of the insights useful if you are really into writing your own code.

See the following code snippet

<?php
function js_start(){
  return '<script type="text/javascript">';
}

function js_add_jquery($version='1.4.2'){
  return '<script src="https://ajax.googleapis.com/ajax/libs/jquery/'.$version.'/jquery.min.js"></script>';
}

function js_ajax($url, $data, $success){
 return "
 $.ajax({
    url: '$url',
    data: '$data',
    success: $success
  });";
}


function js_end(){
  return '</script>';
}


//Example usage:
// where success is behaviour you want executed on success
$success =
"function(data) {
  $('#page').html(data);
}";

echo js_add_jquery(); // default version 1.4.2 is used here
echo js_start();
echo js_ajax('test.php', 'name=John&surname=Doe', $success);
echo js_end();
?>
