phpcms 移植【添加相关文章】功能

添加相关文章功能相当有用,移植一个过来基本上可以实现比较复杂的页面内包含分类功能,做二次开发时可以省下不少力气。

用例:如果一个产品,属于一个厂家,而这个厂家是动态添加的,既不是一个分类,而是一个厂家的模型,这二者关联的时候使用这个添加相关的功能可以轻易实现。

 

学会使用phpcms中的类别管理和推荐位管理基本上可以满足文章管理的多数场景,如果能够理解mysql表的设计,可以使用模型管理这个大杀器,

基本上能够想到的功能都能实现,最后再对【添加相关文章】功能进行设计和移植,模型功能能够再次爆发威力,进行各种关系映射。前台配合ajax和json,以及数据表的query函数可以整合实现相当复杂的功能和页面。

 

 

1,模型管理中添加一个万能字段。

然后在表单栏中填写:

<input type=’hidden’ name=’info[rt]’ id=’rt’ value='{FIELD_VALUE}’ style=’50’ >
<ul class=”list-dot” id=”rt_text”></ul>
<div>
<input type=’button’ value=”添加相关” onclick=”omnipotent(‘selectid’,’?m=content&c=content&a=public_rtlist&modelid=29′,’添加相关文章’,1)” class=”button” style=”width:66px;”>
<span class=”edit_content”>
<input type=’button’ value=”显示已有” onclick=”show_rt({MODELID},{ID})” class=”button” style=”width:66px;”>
</span>
</div>

注意上面的标红字体,需要和相关参数关联

 

2,在文章修改页面添加如下函数

function show_rt(modelid,id) {
$.getJSON(“?<?php echo “token=”.$_SESSION[‘token’];?>&m=content&c=content&a=rt_getjson_ids&modelid=”+modelid+”&id=”+id, function(json){
var newrt_ids = ”;
if(json==null) {
alert(‘没有添加相关文章’);
return false;
}

$.each(json, function(i, n){
newrt_ids += “<li id='”+n.sid+”‘>·<span>”+n.title+”</span><a href=’javascript:;’ class=’close’ onclick=\”remove_rt(‘”+n.sid+”‘,”+n.id+”)\”></a></li>”;
});

$(‘#rt_text’).html(newrt_ids);
});
}

//移除相关文章
function remove_rt(sid,id) {
var rt_ids = $(‘#rt’).val();
if(rt_ids !=” ) {
$(‘#’+sid).remove();
var r_arr = rt_ids.split(‘|’);
var newrt_ids = ”;
$.each(r_arr, function(i, n){
if(n!=id) {
if(i==0) {
newrt_ids = n;
} else {
newrt_ids = newrt_ids+’|’+n;
}
}
});
$(‘#rt’).val(newrt_ids);
}
}

 

3,在content.php中填写如下函数

public function public_rtlist() {
ec_main::get_lib_c(‘format’,”,0);
$show_header = ”;
$model_cache = getcache(‘model’,’commons’);
if(!isset($_GET[‘modelid’])) {
showmessage(L(‘please_select_modelid’));
} else {
$page = intval($_GET[‘page’]);

$modelid = intval($_GET[‘modelid’]);
$this->db->set_model($modelid);
$where = ”;
if($_GET[‘catid’]) {
$catid = intval($_GET[‘catid’]);
$where .= “catid=’$catid'”;
}
$where .= $where ? ‘ AND status=99’ : ‘status=99’;

if(isset($_GET[‘keywords’])) {
$keywords = trim($_GET[‘keywords’]);
$field = $_GET[‘field’];
if(in_array($field, array(‘id’,’title’,’keywords’,’description’))) {
if($field==’id’) {
$where .= ” AND `id` =’$keywords'”;
} else {
$where .= ” AND `$field` like ‘%$keywords%'”;
}
}
}
$infos = $this->db->listinfo($where,”,$page,12);
$pages = $this->db->pages;
include $this->admin_tpl(‘rtlist’);
}
}

public function rt_getjson_ids() {
$modelid = intval($_GET[‘modelid’]);
$id = intval($_GET[‘id’]);
$this->db->set_model($modelid);
$tablename = $this->db->table_name;
$this->db->table_name = $tablename.’_data’;

$r = $this->db->get_one(array(‘id’=>$id),’rt’);

if($r[‘rt’]) {
$rt = str_replace(‘|’, ‘,’, $r[‘rt’]);
$rt = trim($rt,’,’);
$where = “id IN($rt)”;
$infos = array();
$this->db->table_name = ‘ec_chang’;
$datas = $this->db->select($where,’id,title’);
foreach($datas as $_v) {
$_v[‘sid’] = ‘v’.$_v[‘id’];
if(strtolower(CHARSET)==’gbk’) $_v[‘title’] = iconv(‘gbk’, ‘utf-8’, $_v[‘title’]);
$infos[] = $_v;
}
echo json_encode($infos);

}

}

5增加模板rtlist.tpl.php[content/tpl]

<?php
defined(‘IN_ADMIN’) or exit(‘No permission resources.’);
include $this->admin_tpl(‘header’,’admin’);
?>
<div class=”pad-10″>
