I am currently using a foreach loop to display the data from my database on my website but have just tried to include pagination which is using a while loop.
<?php
foreach ($posts as $post): ?>
<div class="post clearfix">
<img src="<?php echo BASE_URL . '/assets/images/' . $post['image']; ?>" alt="" class="post-image">
<div class="post-preview">
<h2><?php echo $post['title']; ?></h2>
<i class="far fa-user"> <?php echo $post['username']; ?></i>
<i class="far fa-calendar"> <?php echo date('F j, Y', strtotime($post['created_at'])); ?></i>
<p class="preview-text">
<?php echo html_entity_decode(substr($post['excerpt'], 0, 150) . '...'); ?>
</p>
Read More
</div>
</div>
<?php endforeach; ?>
while ($row = mysqli_fetch_array($result)) {
}
?>
How do I go about transferring the data here/incorporating them both together into the while loop so that the pagination works smoothly and the data remains displayed as it currently is? Thanks
To convert foreach to while loop. Simply,
Note: if "$posts" is an object array
try this below
<?php
$i=0;
while($i < sizeof($posts)){
$post=$posts[$i++]; ?>
//use $post object in your code
//something like $post['image']
<?php }?>

I have the following function.php:
function getPublishedPosts() {
// use global $conn object in function
global $conn;
$sql = "SELECT * FROM posts WHERE published=true";
$result = mysqli_query($conn, $sql);
// fetch all posts as an associative array called $posts
$posts = mysqli_fetch_all($result, MYSQLI_ASSOC);
$final_posts = array();
foreach ($posts as $post) {
$post['topic'] = getPostTopic($post['id']);
array_push($final_posts, $post);
}
return $final_posts;
}
and I am calling it to the other page with this:
<!-- THIS LOOP -->
<?php $posts = **getPublishedPosts();** ?>
<div class="content">
<h2 class="content-title">Recent Articles</h2>
<hr>
<!-- more content still to come here ... -->
<!-- Add this ... -->
<?php $posts = getPublishedPosts(); ?>
<?php foreach ($posts as $post): ?>
<div class="post" style="margin-left: 0px;">
<img src="<?php echo BASE_URL . '/static/images/' . $post['image']; ?>" class="post_image" alt="">
<!-- Added this if statement... -->
<?php if (isset($post['topic']['name'])): ?>
<a
href="<?php echo BASE_URL . 'filtered_posts.php?topic=' . $post['topic']['id'] ?>"
class="btn category">
<?php echo $post['topic']['name'] ?>
</a>
<?php endif ?>
<a href="single_post.php?post-slug=<?php echo $post['slug']; ?>">
<div class="post_info">
<h3><?php echo $post['title'] ?></h3>
<div class="info">
<span><?php echo date("F j, Y ", strtotime($post["created_at"])); ?></span>
<span class="read_more">Read more...</span>
</div>
</div>
</a>
</div>
<?php endforeach ?>
</div>
However, when it is on the server, the page goes blank.
I finally solved it, it was just a server extension and version problem regarding the incompatibility of my function.
I'd like to achieve on adding a comma between my authors in my foreach but each time I make any references, it adds a comma at the end also.
Here is what I have below:
<div class="four-sixths first">
<img class="mb-20" src="<?= $recipe->get_thumbnail() ?>" alt=""/>
<h2 class="mb-5"><?= $recipe->get_title() ?></h2>
<span><?= $recipe->get_date() ?></span> -
<?php foreach ($recipe->get_authors() as $profile): ?>
<?= $profile->get_name() ?>,
<?php endforeach; ?>
<p><?= $recipe->get_content() ?></p>
</div>
Which gives me the following results:
How can I prevent a comma at the end?
Since you were skeptical about implode, here's a simple example (just showing the loop):
<?php foreach ($recipe->get_authors() as $profile):
$links[] = '' . $profile->get_name() . '';
endforeach; ?>
<?= implode(', ', $links); ?>
An alternative using join:
<div class="four-sixths first">
<img class="mb-20" src="<?= $recipe->get_thumbnail() ?>" alt=""/>
<h2 class="mb-5"><?= $recipe->get_title() ?></h2>
<span><?= $recipe->get_date() ?></span> - <?= join(", ", array_map(function ($profile) { return sprintf('%s', $profile->get_url(), $profile->get_name()); }, $recipe->get_authors())) ?>
<p><?= $recipe->get_content() ?></p>
</div>
Wasn't able to test it but basically store results to $authors first, and in this way you can count it without recalling the method get_authors. While $cnt keeps track base 1 and can be compared directly on the length.
<?php
$authors = $recipe->get_authors();
$cnt = 0;
?>
<div class="four-sixths first">
<img class="mb-20" src="<?= $recipe->get_thumbnail() ?>" alt=""/>
<h2 class="mb-5"><?= $recipe->get_title() ?></h2>
<span><?= $recipe->get_date() ?></span> -
<?php foreach ($authors as $profile) { $cnt++; ?>
<?= $profile->get_name() ?><?php
if ($cnt < count($authors)) echo ",";
?>
<?php } ?>
<p><?= $recipe->get_content() ?></p>
</div>
Hello after I add some code to this PHP foreach the page goes blank and all I can see is a round black dot at the top left of screen.
My website is in Joomla3 and I am trying to customize a module. my site is http://get2gethersports.com
I have a recent post module that only shows the articles title.
that code is posted below
<?php if ($items) { ?>
<ul class="rsblog-recent-module unstyled<?php echo $params->get('moduleclass_sfx',''); ?>">
<?php foreach ($items as $item) { ?>
<li>
<a <?php echo $opener; ?> href="<?php echo JRoute::_('index.php?option=com_rsblog&view=post&id='.RSBlogHelper::sef($item->id,$item->alias).$Itemid,false); ?>">
<?php echo $item->title; ?>
</a>
</li>
<?php } ?>
</ul>
<?php } ?>
I would like to add an image abocve like the blog feed on http://vape-co.com
So I navigated to the component and saw the call for the image. which is posted below:
<div class="rsblog-entry-content">
<?php if ($this->item->image) { ?>
<div class="rsblog-entry-image">
<img class="rsblog-entry-thumb img-polaroid" src="<?php echo JURI::root().'components/com_rsblog/assets/images/blog/'.$this->item->image; ?>?nocache=<?php echo uniqid(''); ?>" alt="<?php echo $this->escape($this->item->title); ?>">
</div>
<?php } ?>
but whenever i add it or a snippet of it to the previous code it breaks....
Any ideas why it is breaking the page and how to fix it?
I tried adding in new li tags. Just adding the PHP part above the a link etc...
CODE UPDATE----
<?php if ($items) { ?>
<ul class="rsblog-recent-module unstyled<?php echo $params->get('moduleclass_sfx',''); ?>">
<?php foreach ($items as $item) { var_dump($item);?>
<li>
<div class="rsblog-entry-content">
<?php if ($this->item->image) { ?>
<div class="rsblog-entry-image">
<img class="rsblog-entry-thumb img-polaroid" src="<?php echo JURI::root().'components/com_rsblog/assets/images/blog/'.$this->item->image; ?>?nocache=<?php echo uniqid(''); ?>" alt="<?php echo $this->escape($this->item->title); ?>">
</div>
</div>
<?php } ?>
<a <?php echo $opener; ?> href="<?php echo JRoute::_('index.php?option=com_rsblog&view=post&id='.RSBlogHelper::sef($item->id,$item->alias).$Itemid,false); ?>">
<?php echo $item->title; ?>
</a>
</li>
<?php } ?>
</ul>
<?php } ?>
Try $item->image instead of $this->item->image
Correct code. Looks like it just needed some reduction.
<?php if ($items) { ?>
<ul class="rsblog-recent-module unstyled<?php echo $params -> get('moduleclass_sfx',''); ?>">
<?php foreach ($items as $item) { ?>
<li>
<?php if($item->image != '') ?>
<img src="components/com_rsblog/assets/images/blog/<?php echo $item->image;?>" alt="<?php echo $item->title. "logo";?>" width="100px"/>
<br/>
<a <?php echo $opener; ?> href="<?php echo JRoute::_('index.php?option=com_rsblog&view=post&id='.RSBlogHelper::sef($item->id,$item->alias).$Itemid,false); ?>">
<?php echo $item->title; ?>
</a>
</li>
<?php } ?>
</ul>
<?php } ?>
I'm making a website with Joomla and am using RokSprocket to display some news. Now, some Titles are too long, so I wanted to shorten it after a certain character number, but it's not working. Am a total php noob, my apologies.
Here's the whole code:
<li data-lists-item>
<h4 class="sprocket-lists-title ">
<?php if ($item->custom_can_have_link): ?><a href="<?php echo $item->getPrimaryLink()->getUrl(); ?>"><?php endif; ?>
<?php if(strlen($item->getTitle)>10)
echo substr($item->getTitle,0,10) . ' ...';
else
echo $item->getTitle();?></a>
<div class="date"><?php echo date('d.M. Y', strtotime($item->getDate()));?></div>
</h4>
<span class="sprocket-lists-item" data-lists-content>
<span class="sprocket-padding">
<?php if ($item->getPrimaryImage()) :?>
<img src="<?php echo $item->getPrimaryImage()->getSource(); ?>" class="sprocket-lists-image" />
<?php endif; ?>
<?php echo $item->getText(); ?>
<?php if ($item->getPrimaryLink()) : ?>
<span><?php rc_e('READ_MORE'); ?></span>
<?php endif; ?>
</span>
</span>
</li>
I'm hoping it's something very obvious and I'm just being stupid. Thanks a bunch already!
$item->getTitle is probably a method not a property, so try:
$item->getTitle(); // <-- parenthesis
Change to:
<?php if(strlen($item->getTitle())>10)
echo substr($item->getTitle(),0,10) . ' ...';
so i guess this is pretty easy for most of you, but i can't figure this out.
im trying to make the links dynamic eg: href="linkname(#1 or #2 etc)"
any ideas?
<?php if ($top_fundraisers && is_array($top_fundraisers)): ?>
<?php foreach ($top_fundraisers as $index => $fundraiser): ?>
<a title="" class="fancybox" href="linkname(GENERATE CODE HERE)">
<div class="top-fundraiser">
<div id="newo<?php print htmlentities($index + 1); ?>" class="top-fundraiser-image">
<img src="<?php
if($fundraiser['member_pic_medium']) {
print htmlentities($fundraiser['member_pic_medium']);
} else {
print $template_dir . '/images/portrait_placeholder.png';
}
?>"/>
</div>
</div>
</a>
<?php endforeach;?>
<?php endif; ?>
Suppose below is what you need.
<?php if ($top_fundraisers && is_array($top_fundraisers)): ?>
<?php foreach ($top_fundraisers as $index => $fundraiser): ?>
<a title="" class="fancybox" href="linkname(#<?php echo $index + 1; ?>)">
<div class="top-fundraiser">
<div id="newo<?php print htmlentities($index + 1); ?>" class="top-fundraiser-image">
<img src="<?php
if($fundraiser['member_pic_medium']) {
print htmlentities($fundraiser['member_pic_medium']);
} else {
print $template_dir . '/images/portrait_placeholder.png';
}
?>"/>
</div>
</div>
</a>
<?php endforeach;?>
<?php endif; ?>
