PHP jquery轮播位置

Question

I'm using php pagination to load different data from a text file. I am using a jquery carousel http://tympanus.net/Development/Elastislide/index4.html that is featured on each page created from the pagination. What I would like to do is, depending on which page you are on, the carousel will load in a different position. To get this working, I'm thinking I would need to change the jquery which loads on each created page?

<script type="text/javascript">
$('#carousel').elastislide({
            imageW      : 110,
            margin      : 20,
            border      : 4,
            easing      : 'easeInBack',
            current     : 12
        });
</script> 

So if the pagination is on the page.php?p=12, the carousel would be on thumbnail 12? Example html:

<div id="carousel" class="es-carousel-wrapper">
    <div class="es-carousel">
        <ul>
            <li><a href="page.php?p=1"><img src="images/img1.jpg" width="100" height="130" alt="image01" /></a></li>
            <li><a href="page.php?p=2"><img src="images/img2.jpg" width="100" height="130" alt="image02" /></a></li>
        </ul>
    </div>
</div>

the pagination i'm using:

<?php
    $data=file("students.txt");
    $pages=0;
    foreach($data as $temp){
        $x=explode("|",$temp);
        if($x[0]>0){
            $pages=$pages+1;
        }
    }
    if($_GET['p']){
        $page=$_GET['p'];
    }
    if($_GET['i']){
        $index=$_GET['i'];
    }  
    if($index == "p"){
        $page=$page-1;
    }
    if($index == "n"){
        $page=$page+1;
    }
    if($page < 1){
        $page=1;
    }
    if($page > $pages){
        $page=$pages;
    } 
    $line=$data[$page-1];
    $fields=explode("|",$line);  
?>

I'm new to PHP and I really don't have a clue on how to put this together...

Does anyone have any ideas how to make this work? :(

Answer 1

Have that PHP be the first thing on the page, then in the carousel script initiation block use:

current : <?=$page?> 

or, if you're unsure whether short tags are enabled:

current : <?php echo $page;?>
