IF HTML element display is none, then do something, ELSE do something else - PHP

Question

Get CSS style from PHP

I want to make an if that will do things, only if div's display is not none. Here is an example:

<div id="div_1" style="display:none;">blah blah blah</div>
<?php if (div_1 display is none){...} else {echo $variable;} ?>

Any idea how will I syntax this part (div_1 display is none)??? If it can be of-course! Thank you in advance!

What are you trying to achieve? You should tell us what the final product looks like, not only one way you think it can be achieved. — Angel Yan, Jan 20 '13 at 15:45
OK. I have made a function that runs a db query and I want to call this function only when `div` isn't `display:none`. — DNA180, Jan 20 '13 at 15:49
Any example or something please? Any link? Thank you for your answer!!! — DNA180, Jan 20 '13 at 15:54

You cant do that server-side. Maybe you can use JavaScript and Jquery is a good tool:

if($('#div_1').css('display') == 'none')
{
    ...
}
else {
    $('#Some_Div').html('...');
}

I see!!! And this example is Jquery right? – DNA180 Jan 20 '13 at 15:42

Why not just use `$('#div_1').is(':visible')`? – BenM Jan 20 '13 at 15:42
Wouldn't that result in an error? PHP executes first as server-side language, then javascript – Jan 20 '13 at 15:47

for non-jquery plain 'ol javascript

if (element.style.display == 'none'){
   //your element is not visible
} else {
   //your element is visible
}

You can use Ajax and JavaScript

<script>
$(document).ready(function() {
if($('#div').is(':hidden')) {
$.ajax({
   url: "file.php",
   type: "POST",
   data: {somedata: "data"}, 
      success: function(msg) {

       $("#div").html(msg);
      }
});
}
else {
//...
}
});
</script>
