I have a while loop and inside the while loop there is an if-else statement. All I want to do is put all the contents of the else statements into one div. It's in Wordpress.
I can't seem to get the logic behind it..
<?php /* The loop */
$i = 1;
?>
<?php while ( have_posts() ) : the_post(); ?>
<?php
static $count = 0;
if ($count == 5) { break; }
else {
?>
<div class="content_container">
<?php
if($i == 1) {
?><span style="width:370px;" class="main active"><?php the_post_thumbnail('full');?></span><?php
} else {
?><span class="child nonactive"><?php the_post_thumbnail('full'); ?></span><?php
}
$i++;
$count++;
?>
</div>
<?php
}
?>
<?php endwhile; ?>
<div class="content_container">
<span <?php if($i == 1) { ?> style="width:370px;" class="main active" <?php } else {?> class="child nonactive" ><?php the_post_thumbnail('full');?></span>
<?php }
$i++;
$count++;
?>
</div>

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($location["count"]) ?></div>
</div>
<?php endif; ?>
</li>
}
I have a repeater using Advanced Custom fields, which when a count reaches a total (of 3) based on an iterative count, I would like to output a div, then reset the counter.
Here's the code, at the moment it's not outputting as it should and I don't know enough about math to get it to work.
Appreciate your assistance :-)
<?php if(have_rows('flexible_row')) : ?>
<div class="row">
<?php if(empty($count)){ $count=1;} while(have_rows('flexible_row')) : the_row(); ?>
<?php if(get_sub_field('column_width') == "One column") { $count = $count+1; ?>
<div class="col-sm-4">
<?php the_sub_field('title');?>
<?php the_sub_field('content');?>
Count is <?php echo $count; ?>
<hr/>
</div>
<?php } if(get_sub_field('column_width') == "Two columns") { $count = $count+2; ?>
<div class="col-sm-8">
<?php the_sub_field('title');?>
<?php the_sub_field('content');?>
Count is <?php echo $counter; ?>
<hr/>
</div>
<?php } else { $count = $count+3; ?>
<div class="col-sm-12">
<?php the_sub_field('title');?>
<?php the_sub_field('content');?>
Count is <?php echo $counter; ?>
<hr/>
</div>
<?php } if ($count == 3) { ?></div><div class="row"><?php $count = 0; } ?>
<?php endwhile; ?>
</div>
<?php endif; ?>
Think I'd got my logic mixed up a bit — I wasn't using the else clauses correctly. Here's the final working code in case anyone stumbles across this in the future:
<?php if(have_rows('flexible_row')) : ?>
<div class="row">
<?php if(empty($count)){ $count=0;} while(have_rows('flexible_row')) : the_row(); ?>
<?php if(get_sub_field('column_width') == "One Column") { $count = $count+1; ?>
<div class="col-sm-4">
<?php the_sub_field('title');?>
<?php the_sub_field('content');?>
</div>
<?php } elseif(get_sub_field('column_width') == "Two Columns") { $count = $count+2; ?>
<div class="col-sm-8">
<?php the_sub_field('title');?>
<?php the_sub_field('content');?>
</div>
<?php } else { $count = $count+3; ?>
<div class="col-sm-12">
<?php the_sub_field('title');?>
<?php the_sub_field('content');?>
</div>
<?php } if ($count == 3) { ?></div><div class="row"><?php $count = 0; } ?>
<?php endwhile; ?>
</div>
You could of course use switch statements too..
<div class="puffar">
<?php
//Set up the objects needed
$my_wp_query = new WP_Query();
$all_wp_pages = $my_wp_query->query(array('post_type' => 'page'));
//Get children
$children = ($post->post_parent) ? get_page_children($post->post_parent, $all_wp_pages) : get_page_children($post->ID, $all_wp_pages);
$i = 0;
//Build custom items
echo "<div class='row'>";
foreach ($children as $child) {
?>
<div class="col-sm-6">
<div class="puff">
<div class="puff-image-holder">
<?php echo get_the_post_thumbnail($child->ID, 'full'); ?>
</div>
<fieldset class="linedHeadline hlmedium">
<legend><?php echo get_the_title($child->ID); ?></legend>
</fieldset>
<?php echo get_field("puff_introtext", $child->ID); ?>
<?php
$values = get_field('puff_lanktext', $child->ID);
if (get_field("popup_eller_lank", $child->ID) == "popup") {
?>
<fieldset class="linedHeadline hlmedium">
<legend><a class="linktopage open-popup"
href="<?php echo get_page_link($child->ID); ?>"><?php echo get_field("puff_lanktext", $child->ID); ?> </a>
</legend>
</fieldset>
<?php
} elseif (get_field("popup_eller_lank", $child->ID) == "extern") {
?>
<fieldset class="linedHeadline hlmedium">
<legend><a class="linktopage"
href="<?php echo get_field("puff_lank", $child->ID); ?>"><?php echo get_field("puff_lanktext", $child->ID); ?> </a>
</legend>
<?php
$i++;
if ($i % 2 == 0) {
echo "</div><div class='row'>";
}
} else {
}
?>
</div>
</div>
<?php } ?>
</div>
</div>
I want every 2 items that's rendered out to be wrapped in a <div class="row">, however I can't figure it out. Can anyone help me?
So basically the row should wrap every 2 elements that is getting looped. I have been stuck on this forever... Hopefully anyone got better expertise than me hehe.
The div="row" should wrap the col-sm-6 and class="puff".
$i = 0;
foreach ($children as $child) {
$i++;
// your code goes here
if($i % 2 == 0) {
echo "</div><div class='row'>";
// reset the counter to 0
$i = 0 ;
}
}
use proper logic
if ($i % 2 == 0) {
echo "</div><div class='row'>";
}
$i++;
First check if its mod by 2 or not (Gives 0 value after MOD), then close div , open new.
Now increase counter . Because for the first time , i will be 0 , then you increment it and then you use logic. So in short counter shoul be incremented at the end only not in between before you do any operation/logic.
Updated
Use code as it is **: issue was you have i++ and your condition in 3rd else if which never executed. So took it outside All and just before foreach.
<div class="puffar">
<?php
//Set up the objects needed
$my_wp_query = new WP_Query();
$all_wp_pages = $my_wp_query->query(array('post_type' => 'page'));
//Get children
$children = ($post->post_parent) ? get_page_children($post->post_parent, $all_wp_pages) : get_page_children($post->ID, $all_wp_pages);
$i = 0;
//Build custom items
echo "<div class='row'>";
foreach ($children as $child) {
?>
<div class="col-sm-6">
<div class="puff">
<div class="puff-image-holder">
<?php echo get_the_post_thumbnail($child->ID, 'full'); ?>
</div>
<fieldset class="linedHeadline hlmedium">
<legend><?php echo get_the_title($child->ID); ?></legend>
</fieldset>
<?php echo get_field("puff_introtext", $child->ID); ?>
<?php
$values = get_field('puff_lanktext', $child->ID);
if (get_field("popup_eller_lank", $child->ID) == "popup") {
?>
<fieldset class="linedHeadline hlmedium">
<legend><a class="linktopage open-popup"
href="<?php echo get_page_link($child->ID); ?>"><?php echo get_field("puff_lanktext", $child->ID); ?> </a>
</legend>
</fieldset>
<?php
} elseif (get_field("popup_eller_lank", $child->ID) == "extern") {
?>
<fieldset class="linedHeadline hlmedium">
<legend><a class="linktopage"
href="<?php echo get_field("puff_lank", $child->ID); ?>"><?php echo get_field("puff_lanktext", $child->ID); ?> </a>
</legend>
<?php
} else {
}
?>
</div>
</div>
<?php
if ($i % 2 == 0) {
echo "</div><div class='row'>";
}
$i++;
} ?>
</div>
</div>
First set $i=0;
if ($i % 2 == 0) {
echo "</div><div class='row'>";
}
$i++;
I think this is a simple problem. But, I don't know how to solve this problem. I have posted my codes below. Here, In this below code if else statement always shows No Sarees. I got the result from mysql table but it always shows with No Sarees text. I have checked this using var_dump($categories) it returns array(0){} . How can I solve this problem?
<?php if ($categories) { ?>
<!--BOF Refine Search Result-->
<div class="refine-search-result">
<?php if (count($categories) <= 5) { ?>
<?php foreach ($categories as $category) { ?>
<div class="refine-block">
<p><?php echo $category['name']; ?></p>
</div>
<?php } ?>
<?php } else { ?>
<?php for ($i = 0; $i < count($categories);) { ?>
<?php $j = $i + ceil(count($categories) / 4); ?>
<?php for (; $i < $j; $i++) { ?>
<?php if (isset($categories[$i])) { ?>
<div class="refine-block">
<p><?php echo $categories[$i]['name']; ?></p>
</div>
<?php } ?>
<?php } ?>
<?php } ?>
<?php } ?>
<div class="clear"></div>
</div><!--EOF Refine Search Result-->
<?php } else {
?>
<div class="refine-search-result">
<div class="refine-block">
<p>No Sarees</p>
</div>
<div class="clear"></div>
</div>
<?php } ?>
If your $categories is empty array then in if($categories) your array is converted to boolean value. If it's empty array (and you say it is) then it's get converted to false.
Check this:
$categories = array(); //empty array
var_dump((boolean)$categories); //this will show what variable will look like after converting to boolean value
if ($categories){
echo '$categories IS NOT empty';
}else{
echo '$categories IS empty';
}
I would add each two result one div class
<?php while ($fetch = $db->fetch($query)) { ?>
<?php echo $fetch['title']; ?>
<?php } ?>
Output should be like this
<div class="one">
<div class="two">
<article>Title</article>
<article>Title</article>
</div>
</div>
<div class="one">
<div class="two">
<article>Title</article>
<article>Title</article>
</div>
</div>>
<?php
$i=0;
while ($fetch = $db->fetch($query)) { ?>
<?php if ($i%2==0) { ?>
<div class="one">
<div class="two">
<?php } ?>
<article><?php echo $fetch['title']; ?></article>
<?php if ($i++%2==1) { ?>
</div>
</div>
<?php } ?>
<?php } ?>
//Also is a good idea to verify if the <div> tags are closed
<?php if ($i%2==1) { ?>
</div>
</div>
<?php } ?>
$count = 0;
while ($fetch = $db->fetch($query))
{
if ($count == 0)
echo '<div class="one"><div class="two">';
if ($count < 2)
echo '<article>'.$fetch['title'].'</article>';
if ($count == 2)
{
echo '</div></div>';
$count = 0;
}
$count++;
}
