thinkphp3.2.3 如何把图片地址合并的字段输出到前台？就是显示图片这样

本帖最后由 u011789405 于 2015-01-22 11:21:03 编辑 实现的是就是文章列表显示文章的图片 TP本身的volist可以输出 但是字段pictureurl 怎么能让前端接收到 直接输出么下面是前端的代码

{$content.pictitle}

描述：{$content.picdescription}

{$content.pictureurl }这里是图片地址字段



标签：{$content.pictag}
上传者：{$content.picauthor}

下面是php输出的结果 我想的是图片主题 有多张图片 一张图片一条记录 相同token查询 然后php在进行数组合并 得到这个结果
这个思路对么 这时候想展示图片 怎么搞 直接查询出图片地址 组成数组 ？

这个字段是不是存成二维数组好 直接volist 里面循环volist遍历出图片地址呢

array(2) {
  [0] => array(14) {
    ["picid"] => string(2) "10"
    ["pictitle"] => string(7) "标题2"
    ["pictoken"] => string(32) "fd1215da5d37e70280b5b55d9f87acda"
    ["piccategroy"] => string(1) "9"
    ["picauthor"] => string(12) "星耀学园"
    ["picposttime"] => string(19) "2014-11-26 11:59:50"
    ["pictag"] => string(22) "标题2自定义标签"
    ["picdescription"] => string(13) "标题2描述"
    ["picalbum"] => string(19) "标题2所属相册"
    ["pictureid"] => string(32) "fd1215da5d37e70280b5b55d9f87acda"
    ["pictureurl"] => string(223) "attachment/picture/uploadify/20141126/547550273b753.jpg,attachment/picture/uploadify/20141126/547550278b7db.jpg,attachment/picture/uploadify/20141126/54755027ab89b.jpg,attachment/picture/uploadify/20141126/54755027d8488.jpg"
    ["creattime"] => string(19) "2014-11-26 11:59:35"
    ["id"] => string(1) "9"
    ["categroyname"] => string(6) "动漫"
  }
  [1] => array(14) {
    ["picid"] => string(2) "15"
    ["pictitle"] => string(30) "测试更新附件状态字段"
    ["pictoken"] => string(32) "8083b0b4bbf1c05108006d3d952a01d5"
    ["piccategroy"] => string(1) "9"
    ["picauthor"] => string(3) "xxx"
    ["picposttime"] => string(19) "2014-12-24 13:40:42"
    ["pictag"] => string(30) "测试更新附件状态字段"
    ["picdescription"] => string(30) "测试更新附件状态字段"
    ["picalbum"] => string(30) "测试更新附件状态字段"
    ["pictureid"] => string(32) "8083b0b4bbf1c05108006d3d952a01d5"
    ["pictureurl"] => string(223) "attachment/picture/uploadify/20141224/549a51d4a089b.jpg,attachment/picture/uploadify/20141224/549a51d4e6b22.jpg,attachment/picture/uploadify/20141224/549a51d51a0ac.jpg,attachment/picture/uploadify/20141224/549a51d543a33.jpg"
    ["creattime"] => string(19) "2014-12-24 13:40:36"
    ["id"] => string(1) "9"
    ["categroyname"] => string(6) "动漫"
  }
}

下面是查询出来的原始数据 还没有合并数组 想根据picid 相同的合并 然后字段pictureurl 组成二维数组
这样前台volist 里面在一层volist是不是可以 求熟悉tp的帮忙看看

array(8) {
  [0] => array(14) {
    ["picid"] => string(2) "10"
    ["pictitle"] => string(7) "标题2"
    ["pictoken"] => string(32) "fd1215da5d37e70280b5b55d9f87acda"
    ["piccategroy"] => string(1) "9"
    ["picauthor"] => string(12) "星耀学园"
    ["picposttime"] => string(19) "2014-11-26 11:59:50"
    ["pictag"] => string(22) "标题2自定义标签"
    ["picdescription"] => string(13) "标题2描述"
    ["picalbum"] => string(19) "标题2所属相册"
    ["pictureid"] => string(32) "fd1215da5d37e70280b5b55d9f87acda"
    ["pictureurl"] => string(55) "attachment/picture/uploadify/20141126/547550273b753.jpg"
    ["creattime"] => string(19) "2014-11-26 11:59:35"
    ["id"] => string(1) "9"
    ["categroyname"] => string(6) "动漫"
  }

------解决思路----------------------
问题不在php，而是数据库结构
如果只考虑代码层面，就组二维数组吧~
------解决思路----------------------
文章一张表，图片一张表
一篇文章一条记录，一张图一条记录，图片根据文章id去关联文章
你的冗余数据比较多，也不方便管理

如果在文章列表中需要显示多图，按理说要多表查询，但这样效率太慢
可以在文章表增加一个字段，将图片地址的数组序列化或json_encode后保存
------解决思路----------------------
不理解你想要什么？
你只有一重 volist，那么你示例的数组不正好吗？

不能是从 php 这边向 html 硬凑的
而是先按期望的样式写好 html 代码，php 只是负责向里面填数据
至于数据该是什么样的，要由 html 代码决定
------解决思路----------------------
我提到序列化或json，是为了将php内存中的数组变成字符串存进数据库，用的时候立刻转回来，跟js没关系
------解决思路----------------------

function picurl($str,$id){
	//if($width == ''){
		$width='200';
	//}

	if($str != ''){
	$str= explode(",", $str);
	$picstr='';
	for ($i=0; $i		$picstr.='$id)).' target="_blank">  ';
	}

	return $picstr;
	}
}

加个函数进去 模板里头调用函数就可以了 放全局函数里头 这个函数修改下
------解决思路----------------------
本来就是分开的，干嘛要合并在一起？
TP 的模型提供有 Relation 方法，本身就是为了解决你这种问题的
在 volist 里面在逃一个 volist 输出图片就可以了
