Reverse Array order in template

[PatrickRQ]

Hi,

I look for a way to reverse array order directly in template and PHP but seems it does not work. I wanted to avoid plugins or direct file modifications for such simple things. Is it actually possible?, example code below.

{{foreach $files as $k => $file}}
            {{$data = $files->data();}}
            <li class='ipsDataItem'>
                <div class='ipsDataItem_main'>
                    <h4 class='ipsDataItem_title ipsContained_container'><span class='ipsType_break ipsContained'>{{if $data['record_realname']}}{$data['record_realname']}{{else}}{{$pathBits = explode( '/', \IPS\Http\Url::external( $data['record_location'] )->data[ \IPS\Http\Url::COMPONENT_PATH ] );}}{expression="\count( $pathBits ) ? array_pop( $pathBits ) : $data['record_location']"}{{endif}}</span></h4>
                    {{if $data['record_size']}}<p class='ipsType_reset ipsDataItem_meta'>{filesize="$data['record_size']"}</p>{{endif}}
                </div>
                {{if $waitingOn == $k}}
                    <div class='ipsDataItem_generic ipsDataItem_size6 ipsType_warning'>
                        <noscript>{lang="wait_x_seconds_noscript" pluralize="$waitingFor"}</noscript>
                    </div>
                {{endif}}
                <div class='ipsDataItem_generic ipsDataItem_size4 ipsType_right'>
                    <span class="ipsHide" data-role="downloadCounterContainer">{lang="download_begins_in"} <span data-role="downloadCounter"></span> {lang="seconds"}</span>
                    <a href='{$fileObject->url('download')->setQueryString( array( 'r' => $k, 'confirm' => 1, 't' => 1, 'version' => isset( \IPS\Request::i()->version ) ? \IPS\Request::i()->version : NULL ) )->csrf()}' class='ipsButton ipsButton_primary ipsButton_small' data-action="download" {{if member.group['idm_wait_period']}}data-wait='true'{{endif}}>{lang="download"}</a>
                </div>
            </li>
        {{endforeach}}

What I want is array_reverse($files, true) but then no file displays in downloads.

 

I tried exactly below code:

{{$data2 = null;}}
{{$data2 = array_reverse($files, true);}}
	{{foreach $data2 as $k => $file}}
		{{$data = $data2->data();}}

$files isn't an array, but an Iterator.

You might be able to do something like

{{foreach array_reverse( iterator_to_array( $files ) ) as $k => $file}}

I haven't tested and I'm not certain that it'll work, but worth a try.

[PatrickRQ]

It works this way but actually fails here

{{$data = $files->data();}}

as the $files are not reversed in this place. I think I need to redesign entire foreach to work with array.

[PatrickRQ]

This is result of the change. Missing info of $data

I wrote this to sort downloads by filename.  You should be able to use it to accomplish the reverse sort by changing the database query accordingly:

<div class='ipsPad'>
	<h1 class='ipsType_pageTitle'>{lang="download_your_files"}</h1>
	<p class='ipsType_reset ipsType_normal ipsType_light'>{lang="download_file_count" pluralize="\count( $files )"}</p>
	<hr class='ipsHr'>
	<ul class='ipsDataList ipsDataList_reducedSpacing'>
      
      {{$fileRecords = \IPS\Db::i()->select('*', 'downloads_files_records', array(array('record_file_id=?', $fileObject->id),'record_backup=0'),'record_realname ASC');}}
		{{foreach $fileRecords as $file}}
		{{$data = $file;}}
		{{$k = $data['record_id'];}}
			
			<li class='ipsDataItem'>
				<div class='ipsDataItem_main'>
					<h4 class='ipsDataItem_title ipsContained_container'><span class='ipsType_break ipsContained'>{{if $data['record_realname']}}{$data['record_realname']}{{else}}{{$pathBits = explode( '/', \IPS\Http\Url::external( $data['record_location'] )->data[ \IPS\Http\Url::COMPONENT_PATH ] );}}{expression="\count( $pathBits ) ? array_pop( $pathBits ) : $data['record_location']"}{{endif}}</span></h4>
					{{if $data['record_size']}}<p class='ipsType_reset ipsDataItem_meta'>{filesize="$data['record_size']"}</p>{{endif}}
				</div>
				{{if $waitingOn == $k}}
					<div class='ipsDataItem_generic ipsDataItem_size6 ipsType_warning'>
						<noscript>{lang="wait_x_seconds_noscript" pluralize="$waitingFor"}</noscript>
					</div>
				{{endif}}
				<div class='ipsDataItem_generic ipsDataItem_size4 ipsType_right'>
					<span class="ipsHide" data-role="downloadCounterContainer">{lang="download_begins_in"} <span data-role="downloadCounter"></span> {lang="seconds"}</span>
					<a href='{$fileObject->url()->setQueryString( array( 'do' => 'download', 'r' => $k, 'confirm' => 1, 't' => 1, 'version' => isset( \IPS\Request::i()->version ) ? \IPS\Request::i()->version : NULL ) )->csrf()}' class='ipsButton ipsButton_primary ipsButton_small' data-action="download" {{if member.group['idm_wait_period']}}data-wait='true'{{endif}}>{lang="download"}</a>
				</div>
			</li>
		{{endforeach}}
	</ul>
</div>

That wouldn't quite work either, it would include screenshots, links from all versions and also include new files that are pending approval

[IPCommerceFan]

Ah, our use case doesn't involve any of that so it wasn't considered. 🤦‍♂️

[PatrickRQ]

That condition make things work

{{$fileRecords = \IPS\Db::i()->select('*', 'downloads_files_records', array(array('record_file_id=?', $fileObject->id),'record_backup=0','record_hidden=0', 'record_type="upload"'),'record_id DESC');}}
