Ok guys I know this question has been asked before but I am very new to PHP and JavaScript and hadn't even heard of ajax until i started looking for an answer to this question so do not understand previous answers.
I am creating a site that essentially is a bunch of videos in a SQL database, it shows one video at a time, I would like to have a next and previous video buttons.
However I cant get past this ajax thing so my question is even simpler. I have looked at this question/answer and think it pretty much sums up what im asking:
How do I run PHP code when a user clicks on a link?
I have copied that exact code,
<script type="text/javascript">
function doSomething() {
$.get("backend.php");
return false;
}
</script>
<a href="#" onclick="doSomething();">Click Me!</a>
And in my backend.php
file i have literally just got <?php echo "Hello" ?>
just to test it and therefore my understanding is that when i click the link the javascript onClick event is trigged which in turn calls the backend.php
file, which says to print "Hello" to the page. However when i click the link it does nothing.
Eventually obviously im going to need to get a lot more complex with my php functions and calling variables and all that stuff but i like to figure things out for myself for the most part so i learn. However im stuck on this bit. Also whilst im here i will ask another thing, I want to 'give back' to the users of the site for answering my questions but I can only really well enough in HTML and CSS to answer other peoples questions, any advice on being able to find the simpler questions on here so i can answer some.
Thanks in advance :)
