phpcms实现轮播的方法：首先在想要加轮播图的位置加入“<div id="flowDiagram" >…</div>”；然后根据自己的需求对css样式进行更改；最后在需要实现轮播的地方加入js代码即可。

phpcms首页实现轮播图

1.在你想要加轮播图的位置加入以下

<div id="flowDiagram" >
          <div id="button">
            <span index="1" class="on"></span>
            <span index="2"></span>
            <span index="3"></span>
            <span index="4"></span>
              <span index="5"></span>
          </div>
          <div id="photo" style="left:-1200px;">
        <div>
           {pc:content  action="position" posid="1" thumb="1" order="listorder DESC" num="5"}
        {loop $data $r}
        <div ><a href="{$r[url]}" target="_blank" title="{$r[title]}"><img src="{thumb$r[thumb],1200,320)}" style="width:1200px; height:320px;" alt="{$r[title]}" /></a></div>
        {/loop}
        {/pc}
        <ul>
        {pc:content  action="lists" catid="" thumb="1" order="listorder DESC" num="5"}
        {loop $data $r}
        <li><a href="{$r[url]}" target="_blank" title="{$r[title]}">{str_cut$r[title],20)}</a></li>
        {/loop}
        {/pc}
        </ul>
        <div></div>
        </div>
        </div>
<span id="pre" class="arrow"> <</span>
<span id="next" class="arrow">> </span>
    </div>

由于这个焦点幻灯比较特殊，图片和文字需要两次调用，另外，后台添加内容时要勾选首页焦点图推荐，就可以添加到首页

2.当然，这里面的css样式根据自己的需求做更改，在这里就不贴出css代码了，实现轮播需要加入以下js代码

window.onload=function){//获取元素
    var flowDiagram = document.getElementById'flowDiagram');//容器
    var photo = document.getElementById"photo");
    var button = document.getElementById"button").getElementsByTagName'span');
    var pre = document.getElementById"pre");
    var next = document.getElementById"next");
    var index = 1;
    var m;

    function move){
        m = setIntervalnext.onclick,3000);
    }
    function stop){
        ifm)clearIntervalm);
    }
    function buttonlight){
        for var i = 0; i < button.length; i++) {
            ifbutton[i].className == "on"){
                button[i].className = "";
                break;
            }
        }
        button[index-1].className = "on";
    }

    pre.onclick=function) {
        if index == 1)
            index = 5;
        else
              index = index - 1;
        buttonlight);
        photo.style.left = parseIntphoto.style.left) + 1200 + "px";
        if parseIntphoto.style.left) > -1200){
            photo.style.left = -6000 + "px";
       }
    }

    next.onclick = function){//当right键被触发时响应
        if index == 5)
            index = 1;
        else
            index = index + 1;
        buttonlight);
        photo.style.left = parseIntphoto.style.left) - 1200 + "px";
        if parseIntphoto.style.left) < -6000){
            photo.style.left = -1200 + "px";
        }
    }

    for var i = 0; i < button.length; i++){
        button[i].onclick = function)
        {
            ifthis.className=="on")
                return;
            var currentindex = parseIntthis.getAttribute"index"));//getAttribute能获取自定义的属性值，也可以获取自带的属性值
            var distance = currentindex - index;
            photo.style.left = parseIntphoto.style.left) - 1200 * distance + "px";
            index = currentindex;
            buttonlight);
        }
    }
    flowDiagram.onmouseover = stop;
    flowDiagram.onmouseout = move;
    move);
}

最终效果
