Stop FOREACH looping using BREAK (PHP)

Hi,
The popunpoblog module block shows topics on a block by usage of a FOREACH. But I want the block to show only the first topic. To do so I need to stop the FOREACH loop using the BREAK comand. '

I read how to use it on PHP Files, but not in HTML files as it:



<{foreach item=blog_user from=$block.popnupblog}>
<table class="outer" cellspacing="0" cellpadding="5" width="100%">
<tr bgcolor="#f4f4f4">
<td bgcolor="#f4f4f4">
<font color="#999999"><strong><{$blog_user.last_update_s}></strong>
<{$blog_user.title}></font><br>
<font color="#000000" size="3" face="Verdana, Arial, Helvetica, sans-serif"><strong><{$blog_user.last_title}></strong></font>
</td>
<td>&nbsp; </td><td>&nbsp; </td>
</tr>
<td colspan=4>
<{$blog_user.last_text|replace:"img":"img hspace='5'"}>
</td>
</tr><tr>
<td align="right"><{$blog_user.commentuname}> </TD>
<td colspan=3><{$blog_user.comment}></TD>
</tr>
<{/foreach}>


I thank any help!!

Re: Stop FOREACH looping using BREAK (PHP)

I'd tried and received the following:
This page cannot be displayed due to an internal error.

You can provide the following information to the administrators of this site to help them solve the problem:

Error: Smarty error: [in db:popnupblog_block_1.html line 20]: syntax error: unrecognized tag 'break' (Smarty_Compiler.class.php, line 580)


I'd tried to erease the foreach as well and it works: It showed only one loop, but it was showed the first post, but I want to be shown the last one

Assign a name value then use the Smarty 'first' or 'last' construction.

e.g. Pseudo code
<{foreach item=blog_user from=$block.popnupblog [color=FF0000]name=foo[/color]}>
    <{if $smarty.foreach.foo.last}>
    ...
    <{else}>
    ...
    <{/if}>
<{/foreach}>


More details in the manual.

Re: Stop FOREACH looping using BREAK (PHP)

Hi, First I'm newbe on PHP, second this popunupblog is a very complex module and I could see that the variables used in the template above is used in other templates, if I chang it, it may inflict on changes in other template files.

Is it really neccessary to get the result wanted?
Is it possible to have the result wanted by changing only the html tamplete above?

I thought about BREAK, but I cant't understand -the template has the FOREACH comand, but when I add BREAK comand, there are error-. Is it possible that the PHP file restrict some comandas on template?

JCDunnart I read the manual, but if this were the only solution, I'll have a big job...

Thanks!!

Smarty doesn't have a <{break}> tag; that's why it causes an error.

JCDunnart's method should do exactly what you want, except you can omit the <{else}> part:

<{foreach item=blog_user from=$block.popnupblog name=foo}>
    <{if $smarty.foreach.foo.last}>
    ...
    <{/if}>
<{/foreach}>


Just replace the "..." with the code currently in the body of the <{foreach}>.

That's some nice staff, but going with it a bit further ....

If I want to divide the block into 2 collums and I made it show 10 records altogether -
Will the following code give a result of 5 of the records in the first cell and the rest of the 10 in the second cell ?

<table>
<tr>
    <td><{foreach item=blog_user from=$block.popnupblog name=foo}>
    <{if $smarty.foreach.5.last}>
    ...
    <{/if}>
<{/foreach}></td>
    <td><{foreach item=blog_user from=$block.popnupblog name=foo}>
    <{if $smarty.foreach.6.first}>
    ...
    <{/if}>
<{/foreach}></td>
</tr>
</table>


??????????????????

ohh, yes I saw it's not the right code ....

the first 5 records should probably be:
<td><{foreach item=blog_user from=$block.popnupblog name=foo}>
    <{if $smarty.foreach.foo.5}>
    ...
    <{/if}>
<{/foreach}></td>


But How can I start from record no. 6 till the last 10th ?
