Question

我想创建foreach smarty loop with counter和3＆＃34; if＆＃34;里面的条件。在我的计数器值大于3之后，我想重置计数器值并返回到If

的第一个条件

这是我的代码

{foreach $itemscollection as $singleitem name=smartyloop}
     {assign var="counter" value=$smarty.foreach.smartyloop.iteration}

     {if $counter == 1}
          <h1>I am the one</h1>
         {/if}
     {if $counter == 2}
         <h1>I am  second</h1>
     {/if}
     {if $counter == 3}
         <h1>I am  third</h1>
     {/if}
     {if $counter > 3}
     {$counter = 1}
     {/if]

 {/foreach}

例如，如果我有4个元素放入foreach输出应该看起来像

I am the one
I am second
I am third 
I am the one

现在它不工作，我不知道为什么。有人可以帮助我，并告诉如何解决这个问题？

Answer 1

{assign var=counter value=1}
{foreach $itemscollection as $singleitem name=smartyloop}
      {if $counter == 1}
          <h1>I am the one</h1>
      {/if}
      {if $counter == 2}
          <h1>I am  second</h1>
      {/if}
      {if $counter == 3}
          <h1>I am  third</h1>
      {/if}
      {if $counter > 3}
          {assign var=counter value=1}
      {/if]

      {$counter++}
{/foreach}

这可能有效

我知道这是一个旧的但是尝试使用counter作为smarty的自定义函数：

{foreach $itemscollection as $singleitem name=smartyloop}
    {counter assign='pos'} {* assign counter to variable *}

    {if $pos == 1}
        <h1>I am the one</h1>
    {/if}
    {if $pos == 2}
        <h1>I am  second</h1>
    {/if}
    {if $pos == 3}
        <h1>I am  third</h1>
        {counter start=0} {*reset counter*}
    {/if}
{/foreach}

必须回到CMS Made Simple才能做出相关的事情;）

Answer 3

尝试

{if $counter%3 eq 0 && $counter gt 2}
    {assign var=counter value=1}
{/if}

Answer 4

此解决方案正在运行我不知道为什么，也许foreach检查从最后到第一的条件。

  {foreach $blogscollection as $singleblog name=smartyloop}
                {assign var="counter" value=$smarty.foreach.smartyloop.iteration}
                {if $counter>3}
                    {assign var=counter value=1}
                {/if}
                {if $counter == 1}
                    <h1>I am the one</h1>
                {/if}
                {if $counter == 2}
                    <h1>I am the second</h1>
                {/if}
                {if $counter == 3}
                    <h1>I am the third</h1>
                {/if}
            {/foreach}

Answer 5

<?php
$array=array(' the ','hap',' pop' ,' grand'); // assume this is your array to pass in for   each
$says=array(' the one','second',' third');  // store your word to appear
$count=0;
foreach ($array as $arr){
if($count == 3) $count=0;
 print "<h1>I am $says[$count]<h1>";
$count++;
}
?>

Answer 6

You can use {cycle} http://www.smarty.net/docs/en/language.function.cycle.tpl

{cycle name="counter" values="1,2,3"}

Or you could use the Modulus(%) operator http://php.net/manual/en/language.operators.arithmetic.php

{$counter = ($smarty.foreach.smartyloop.iteration % 3) + 1}

Smarty foreach计数器，3元素后复位
