you're missing the { after the foreach and at the end of the loop.
<?php foreach ($widget->items as $key => $item) {
$navigation[] = '<li><span></span></li>';
$captions[] = '<li>'.(isset($item['caption']) ? $item['caption']:"").'</li>';
/* Lazy Loading */
$item["content"] = ($i==$settings['index']) ? $item["content"] : $this['image']->prepareLazyload($item["content"]);
?>
<li>
<article class="wk-content clearfix"><?php echo $item['content']; ?></article>
</li>
<?php
$i=$i+1;
}
?>
Your foreach syntax looks fine. That syntax is a lot easier for some people to read when embedded in HTML than the traditional braces.
Can I ask what the $this variable refers to? I don't see this instantiated anywhere in your code? Is it supposed to be $item instead?
$settings['index'] never changes within the loop, however $i does.
Change to: ($i<2)

How to use joomla pagination in my custom foreach loop data.
//My code
<?php foreach ($items as $item) : ?>
<h2><?= $item->name ?></h2> // data
<?php endforeach; ?>
//This code show pagination but not working
$total = count($items);
jimport('joomla.html.pagination');
$pagination = new JPagination($total, 0 , 1);
echo $pagination->getPagesLinks();
echo $pagination->getPagesCounter();
Can you give a best solution?
I don't have any idea to use joomla pagination.
So I create custom pagination.
<?php //my code
$nItemsPerPage = 1;
$nOfPage=intval(count($items)/$nItemsPerPage)+1;
$page = isset($_GET['page'])?intval($_GET['page']-1):0;
foreach(array_slice($items, $nItemsPerPage*($page-1), $nItemsPerPage) as $item):
echo $item->title; //output
endforeach;
?>
//pagination
<ul>
<?php
for($i=1;$i<$nOfPage;$i++) { ?>
<li><a href='?page=<?php echo $i; ?>'><?php echo $i ?></a></li>
<?php } ?>
</ul>
~~~~~~~~~~~~~Thank You~~~~~~~~~~
How could I limit this foraech statement to just 5 loops? I think I should just use Break but I'm not sure where to put it.
<?php if(!empty($locations)): foreach($locations as $location): ?>
<?php if(empty($location["title"])) continue; ?>
<li>
<a href="<?php esc_attr_e($url.$glue.http_build_query($location["query"])) ?>">
<?php esc_html_e($location["title"]) ?>
</a>
<?php if($param->count): ?>
<div class="wpjb-widget-item-count">
<div class="wpjb-widget-item-num"><?php echo intval($location["count"]) ?></div>
</div>
<?php endif; ?>
</li>
<?php endforeach; ?>
You can use array_slice() first to get a new array with no more than 5 elements.
$locations = array_slice($locations, 0, 5);
Then everything unchanged.
There are three methods:
Method 1: foreach with a counter var
$counter = 1;
foreach($locations as $location) {
// use $location here
if($counter++ == 5) {
break;
}
}
Method 2: foreach using $key=>$val
foreach($locations as $key=>$val) {
// Your content goes here
if($key === 4) {
break;
}
}
Method 3: for loop
for($i = 0; $i < 5; $i++) {
// Use $locations[$i] here and do something with it
}
Using a counter variable into your loop you can control/limit to any number.
Example:
$counter = 0;
foreach($locations as $location):
if($counter++ == 5):
break;
// Your other content goes here
endif;
endforeach;
Add a variable ... increment it each iteration ... after reach 5 just break loop.
<?php $i = 1;?>
<?php if(!empty($locations)): foreach($locations as $location): ?>
<?php if(empty($location["title"])) continue; ?>
<li>
<a href="<?php esc_attr_e($url.$glue.http_build_query($location["query"])) ?>">
<?php esc_html_e($location["title"]) ?>
</a>
<?php if($param->count): ?>
<div class="wpjb-widget-item-count">
<div class="wpjb-widget-item-num"><?php echo intval($location["count"]) ?></div>
</div>
<?php endif; ?>
</li>
<?php if ($i++ == 5) break; ?>
<?php endforeach; ?>
You can use for():
<?php if(!empty($locations)):
for($i=0; $i<5; $i++) {
$location = $locations[$i];
<?php if(empty($locations["title"])) continue; ?>
<li>
<a href="<?php esc_attr_e($url.$glue.http_build_query($location["query"])) ?>">
<?php esc_html_e($location["title"]) ?>
</a>
<?php if($param->count): ?>
<div class="wpjb-widget-item-count">
<div class="wpjb-widget-item-num"><?php echo intval($location["count"]) ?></div>
</div>
<?php endif; ?>
</li>
}
I have some php generated magento top-links with a screenshot below:
My goal is to separate the "Log In" link and have it floated to the left of the same row.
I am hoping for an efficient way to select the last generated list item element and apply some CSS to it.
The code is below:
<ul class="links pull-right"<?php if($this->getName()): ?> id="<?php echo $this->getName() ?>"<?php endif;?>>
<?php foreach($_links as $_link): ?>
<?php if ($_link instanceof Mage_Core_Block_Abstract):?>
<?php echo $_link->toHtml() ?>
<?php else: ?>
<li<?php if($_link->getIsFirst()||$_link->getIsLast()): ?> class="<?php if($_link->getIsFirst()): ?>first<?php endif; ?><?php if($_link->getIsLast()): ?> last<?php endif; ?>"<?php endif; ?> <?php echo $_link->getLiParams() ?>><?php echo $_link->getBeforeText() ?><a href="<?php echo $_link->getUrl() ?>" title="<?php echo $_link->getTitle() ?>" <?php echo $_link->getAParams() ?>><?php echo $_link->getLabel() ?></a><?php echo $_link->getAfterText() ?></li>
<?php endif;?>
<?php if (! $_link->getIsLast()):?>|<?php endif;?>
<?php endforeach; ?>
</ul>
Any ideas would be greatly appreciated!
CSS offers a way to style the last-child of a collection, no tinkering with PHP required.
http://tinker.io/926d2
ul.links.pull-right :last-child {
margin-left: 2em;
}
I answered a similar question not long ago. This adds the class "last-item" to the last item processed.
<?php list($parent) = split('/', $this->url); ?>
<?php $last_articles = $this->find('/news')->children(array('limit'=>5, 'order'=>'page.created_on DESC')); ?>
<ul id="latest-news">
<?php $count = count($last_articles); $num = 0; ?>
<?php foreach ($last_articles as $article): ?>
<li <?php if($num == $count-1){ ?> class="last-item" <?php } ?>>
<?php echo '<h3>'.$article->link($article->title()).'</h3>'; ?>
<?php echo strip_tags(substr($article->content(),0,100)).'...'; ?>
</li>
<?php $num++ ?>
<?php endforeach; ?>
</ul>
Evening All,
Id try and limit the amount of business logic you are adding to your templates. As what you are looking to achieve is custom to this instance of magento I would create a very basic module. I would then look to either implement a new block or just a helper function that will return the data you want.
If your working on the block function ensure your class extends the Magento navigation class. ( Sorry I have not checked what this is ) Then create the action: E.g.
public function getNavigation()
{
$links = $this->getLinks();
$linkArray = array();
$linkCount = count($links);
$i;
foreach($links as $link) {
if($i == $linkCount) {
$last = true;
} else {
$last = false;
}
$linkArray[] = 'link' => $link->getLink()->toHtml(),
'isLast' => $last
$i++;
}
return $linkArray();
}
Your block would then have minimal logic applied. Mainly just iterating through the result set.
Hope that makes sense, If not let me know and I will get you what you require.
I've created a loop to list a set of meta values. I've been able to apply a class to the last item in the list, but I'd like to remove the "," at the end of the last value. Any help would be much appreciated.
<?php $count = count($subcategory); $num = 0; ?>
<?php foreach ($subcategory as $subcategory): ?>
<p
<?php if($num == $count-1){ ?>
class="subcategory-item subcategory-last-item inline-block"
<?php } ?>
class="inline-block subcategory-item"> <?php echo $subcategory;?>,</p>
<?php $num++ ?>
<?php endforeach; ?>
I may be taking an incorrect route by worrying about adding a class to the last item. If I can remove the "," from the last item I'll be happy.
Here's a quick rewrite which may lead you to a solution:
<?php $count = count($subcategories); $num = 0; ?>
<?php $classes = 'inline-block subcategory-item'; ?>
<?php foreach ($subcategories as $subcategory): ?>
<p class="<?=$classes.($num==$count-1?' subcategory-last-item':'')?>">
<?php echo $subcategory;?>
<?php if ($num<$count-1): ?>
,
<?php endif; ?>
</p>
<?php $num++ ?>
<?php endforeach; ?>
I am trying to give an alternate class to each LI foreach.
i.e.
<li class="odd">
text
</li>
<li class="even">
text
</li>
<li class="odd">
text
</li>
<li class="even">
text
</li>
This is my code:
<ul>
<?php foreach ($this->item->extra_fields as $key=>$extraField): ?>
<?php if($extraField->value): ?>
<li class="<?php echo ($key%2) ? "odd" : "even"; ?> type<?php echo ucfirst($extraField->type); ?> group<?php echo $extraField->group; ?>">
Text here
</li>
<?php endif; ?>
<?php endforeach; ?>
</ul>
Please can anyone help...
Thanks
try :
<?php $count = 0; // need to set first value
<?php foreach ($this->item->extra_fields as $key=>$extraField): ?>
<?php if($extraField->value): ?>
<li class="<?php echo (++$count % 2) ? "odd" : "even"; ?> type <?php echo ucfirst($extraField->type); ?> group<?php echo $extraField->group; ?>">
Text here
</li>
<?php endif; ?>
<?php endforeach; ?>
Link to pre/post increment docs if needed
I would do it that way .. it's key independent and you better see what the li-class will look like.
<ul>
<?php
foreach ($this->item->extra_fields as $key=>$extraField) {
if($extraField->value) {
$toggle = ($toggle=="odd"?"even":"odd");
echo '<li class="',$toggle,' type',ucfirst($extraField->type),' group', $extraField->group,'">';
echo 'Text here';
echo '</li>';
}
}
?>
</ul>
jQuery can easily do this if that's an option for you. It's :odd and :even selectors should do just what you're looking for without too much hassle.
I know this is old, but I humbly present a cleaner solution:
<ul>
<?php
$odd = true;
foreach ( $this->item->extra_fields as $key => $extraField ) {
// Output template.
$template = '<li class="%1$s">%2$s</li>';
// Create our classes.
$classes = [
( $odd ) ? 'odd' : 'even',
'type' . ucfirst($extraField->type),
'group' . $extraField->group
];
// Create our class string.
$class_string = implode( ' ', $classes );
// Print our content out.
printf( $template, $class_string, 'Text here' );
// Flip the classname for next time.
$odd = ! $odd;
}
?>
</ul>
It could of course be cleaner still, by using fewer variables. This is just my style.
