I´m trying to remove a div with jquery but I don´t know how can I refer to the ID because it´s a PHP var: id="delete$count"
My Javascript code:
<script type="text/javascript">
function deleteFile(fname,directory)
{
$.ajax({ url: "delete_img.php",
data: {"file":fname,"directory":directory},
type: 'post',
success: function(output) {
alert(output);
$('div').remove();
}
});
}
</script>
My PHP code:
$count=1;
echo '<div class="gallery-item" id="delete$count"></div>';
echo "<div><a class='ico ico-delete' rel='9' rev='2' href='#'onclick='deleteFile(\"$file\",\"$directory\")'>
</a></div>";
$count++;

Answer 1

I think the below will send delete$count verbatim to the response stream without evaluating $count
echo '<div class="gallery-item" id="delete$count"></div>';
Change it to
echo "<div class='gallery-item' id='delete$count'></div>";
so as for PHP to interpolate $count.
Try then passing this as a third parameter to your function as
echo "<div><a class='ico ico-delete' rel='9' rev='2' href='#'onclick='deleteFile(\"$file\",\"$directory\",\"delete$count\")'>
and collect its value in a third argument to
function deleteFile(fname,directory, deletecount) { }
and replace
$('div').remove();
by $('#' + deletecount).remove();

Answer 2

If i understund correctly, you want to achieve the following:
use AJAX to tell server to delete file
remove same file from current view without reloading page
If you read file information from database, i would suggest you to use row-id or something similar as 'gallery-item' ids, and as argument for deleteFile() function.
In case you dont, you can use paired value of $directory and $file instead.
echo '<div class="gallery-item" id="'. $directory . $file . '" ></div>';
echo "<div><a class='ico ico-delete' rel='9' rev='2' href='#'onclick='deleteFile(\"$file\",\"$directory\")'>
</a></div>";
With this, you can replace your $('div').remove() with$('#'+directory+fname).remove()
