Smarty foreach循环

Question

我有smarty的问题，实际上我无法从数据库收集循环数据。

这是getreputation功能

function getreputation($username) 
{ 
global $rDB; 

$rows = $rDB->select(' 
    SELECT * 
    FROM account_reputation 
    WHERE username=? 
    ORDER BY id DESC 
    ', 
    $username 
); 

foreach($rows as $row) 
{ 
    $reputation = array(); 
    $reputation['user'] = $row['username']; 
    $reputation['reputation'] = $row['reputation']; 
    $reputation['action'] = $row['reason']; 
    $reputation['date'] = $row['date']; 
} 

return $reputation; 
} 

下面是我给你这个功能TPL

$smarty->assign('reputation', getreputation($page['username'])); 

而且finaly这是foreach循环

{foreach from=$reputation item=reputation} 
<tr><td width="33%"><center> 
{if $reputation.action == 1}Registering an account 
{elseif $reputation.action == 2}Daily visit 
{elseif $reputation.action == 3}Posting a comment 
{elseif $reputation.action == 4}Your comment was voted up (each upvote) 
{elseif $reputation.action == 5}Submitting a screenshot 
{elseif $reputation.action == 6}Submitting a guide (approved) 
{elseif $reputation.action == 7}Earning a <font color="brown">Copper</font> <a href="/?website-achievements">website achievement</a> 
{elseif $reputation.action == 8}Earning a Silver <a href="/?website-achievements">website achievement</a> 
{elseif $reputation.action == 9}Earning a <font color="gold">Gold</font> <a href="/?website-achievements">website achievement</a> 
{else}Achievement not found 
{/if} 
</center></td><td width="33%"> 
<center><font color='green'>+{$reputation.reputation} 
</font></center></td><td width="33%"><center> 
{$reputation.date} 
</center></td></tr> 
{/foreach} 

所有我能看到是

因此，foreach的输出是完全错误的 有人可以帮助我解决这个问题吗？

Answer 1

首先，您在此处发布的PHP函数永远不会返回多行，因为您一直覆盖$reputation的值。

function getreputation($username) { 
    global $rDB; 
    $rows = $rDB->select('SELECT * FROM account_reputation WHERE username=? ORDER BY id DESC', $username); 

    // Initialize the array that will be filled with the single rows 
    $reputation = array(); 
    foreach($rows as $row) { 
     // Create a temporal variable with a different name 
     $rep = array(); 
     $rep['user'] = $row['username']; 
     $rep['reputation'] = $row['reputation']; 
     $rep['action'] = $row['reason']; 
     $rep['date'] = $row['date']; 

     // Add this array to the other one 
     $reputation[] = $rep; 
    } 

    return $reputation; 
} 

然后，在你的Smarty代码，你应该使用不同的变量名称为当前项目（由迈克尔Berkowski建议）：

{foreach from=$reputation item=rep} 
    <tr><td width="33%"><center> 
    {if $rep.action == 1}Registering an account 
    {elseif $rep.action == 2}Daily visit 
    etc... 
    {else}Achievement not found 
    {/if} 
    </center></td> 

    <td width="33%"><center><font color='green'>+{$rep.reputation} 
    </font></center></td> 
    <td width="33%"><center>{$rep.date}</center></td> 
    </tr> 
{/foreach}
