There are two tags in thinkphp6 that can realize array looping (volist tag and foreach tag). Let's follow the editor to see the use of these two tags.
First type: volist tag
Syntax:
{volist name="" id="" key="" offset="" length=""} 循环体 {/volist}
Among them:
name: the variable name of the current template;
id: the current loop variable;
key: subscript, starting from 1 by default;
offset: the starting line number;
length: the obtained line number.
Example:
Define array:
<?php namespace app\controller; use think\facade\View; class Test{ public function index(){ $arr=[ ['id'=>1,'name'=>'cmcc' ],['id'=>2,'name'=>'cctv' ],['id'=>1,'name'=>'cmqq' ] ]; view::assign('arr',$arr); return view::fetch(); } } ?>
Traverse in template:
{volist name="arr" id="vv" key="kk" offset="1" length="1"} <div> {$kk} --- {$vv['name']} </div> {/volist}
Output result:
We set the interception to start from 1 and intercept one, so the output result is cctv
.
Second type: foreach tag
Syntax:
{foreach $name as $key=>$id} 循环体 {/foreach}
Among them:
foreach is the same as that of
volist, so we won’t write it here anymore, we will directly Look at the traversal in the template.
{foreach $arr as $k=>$v} <div> {$k} --- {$v['name']} </div> {/foreach}The output result is:
We can see that the foreach
tag needs to be added when looping. #$ (dollar sign), and the
volist tag does not need to be added with
$ (dollar sign) when recycling.
