Question

Consider, I’ve got this code in PHP

<?php
if($count==0)
{
?>
<script>
  show_my_div();
</script>
<?php } ?>

the show_my_div() is supposed to show a division tag. But It doesn’t work. Please help.

Answer 1

There’s no standard show_my_div function in PHP or JavaScript. You’d have to post the content of that function for anyone to help you with it.

Outputting a div is easy in PHP:

echo "<div>content</div>";

Similarly, it’s easy in JavaScript to create a div element and append it to something. Here’s raw JavaScript to append a div to the end of the page:

var div = document.createElement('div');
div.innerHTML = "The content of the div";
document.body.appendChild(div);

You can append elements anywhere, not just at the end. For instance, suppose I have a div with the id foo:

<div id="foo"></div>

…and I want to add a paragraph to the end of it:

var p, div;
div = document.getElementById('foo');
if (div) { // (Just being defensive)
    p = document.createElement('p');
    p.innerHTML = "The text of the paragraph";
    div.appendChild(p);
}

These things are made easier if you use a JavaScript library like Prototype, jQuery, Closure, or any of several others to smooth out browser differences and give you some syntactic sugar.
