I have the following PHP array structure:
$set = array();
$set[] = array('firstname'=>'firstname 1',
'lastname'=>'lastname 1',
"bio"=>array('paragraph 1 of the bio, 'paragraph 2 of the bio','paragraph 3 of the bio'),
);
I then access the array with the following:
<?php $counter = 0;
while ($counter < 1) : //1 for now
$item = $set[$counter]?>
<h1><?php echo $item['firstname'] ?></h1>
<h1><?php echo $item['lastname'] ?></h1>
<?php endwhile; ?>
I'm uncertain how I can loop through the "bio" part of the array and echo each paragraph.
So as a final output, I should have two h1s (first and last name) and three paragraphs (the bio).
How can I go about doing this?
Use foreach loop
foreach($item['bio'] as $listitem) {
echo $listitem;
}
You don't need to use a manual counter, you can use foreach. It's generally the easiest way and prevents off-by-one errors.
Then you need a second inner loop to loop through the bio.
<?php foreach ($set as $item): ?>
<h1><?php echo $item['firstname'] ?></h1>
<h1><?php echo $item['lastname'] ?></h1>
<?php foreach ($item['bio'] as $bio): ?>
<p><?php echo $bio; ?></p>
<?php endforeach; ?>
<?php endforeach; ?>
On a related note; you probably want to look into escaping your output.
Add into the while loop also this:
<?php foreach ($item['bio'] as $paragraph): ?>
<p><?php echo $paragraph; ?></p>
<?php endforeach; ?>
Note that used coding style is not optimal.
Try:
foreach($set as $listitem) {
if(is_array($listitem)) {
foreach($listitem as $v) //as $set['bio'] is an array
echo '<h1>' .$v . '</h1>';
} else
echo '<p>'.$listitem.'</p>';
}

I get the result from my database i this type of array format.Now i want to print the question,answer and category name from the array what I do?
<?php $v1 = '';
foreach($var as $data){
?>
<div class="faqHeader"> <?php echo $data['category_name'];?> </div>
<div class="panel-group" id="<?php echo $data->title;?>">
I tried these cod but not get the answer.In $var i get the all the array value
Things to consider:-
1.Your sub-array is again an array so you need to use foreach() on sub-array too. (So basically two foreach())
2.You need to close divs as well as foreach() loops too.
So code need to be like below:-
<?php
foreach($var as $data){
foreach($data['data'] as $dat){
?>
<div class="faqHeader"> <?php echo $dat['category_name'];?>
<div class="panel-group" id="<?php echo $dat['questions'];?>"><?php echo $dat['questions'];?></div>
<div class="panel-group" id="<?php echo $dat['answer'];?>"><?php echo $dat['answer'];?></div>
</div>
<?php } }?>
you can use two loops to simplify your task:-
foreach($var as $index=>data){
echo $data['name']; // this will be your category name
foreach($data as $questionIndex=>$questionData){
echo $questionData['question'];
echo $questionData['answer'];
}
}
Since your array contains multiple data and data contains multiple values itself, you need two foreaches here:
foreach($var as $item) {
foreach($item['data'] as $info) {
var_dump($info);
}
}
Please try this code
<?php
$v1 = '';
foreach($var as $data){
?>
<div class="faqHeader"> <?php echo $data['data'][0]['category_name'];?> </div>
<div class="panel-group" id="<?php echo $data['name'];?>">
<?php
}
?>
You don't have any 'title' index in your array so you may change it to 'name'
I have next code for WordPress loop of tags for single post:
<?php if ($tags) : foreach($tags as $tag): ?>
<a href="<?php echo get_tag_link($tag); ?>">
<?php echo $tag->name; ?>
</a>,
<?php endforeach; endif; ?>
I have comma added to last anchor. There is also white space after comma.
How can I remove the comma from last anchor while I am doing this with foreach() PHP loop?
Thanks for ideas and help!
Check if your loop is working on the last one:
<?php if ($tags) : ?>
<?php $count = count($tags); ?>
<?php foreach($tags as $i => $tag): ?>
<a href="<?php echo get_tag_link($tag); ?>">
<?php echo $tag->name; ?>
</a>
<?php if ($i < $count - 1) echo ", "; ?>
<?php endforeach; ?>
<?php endif; ?>
What has a higher cost, calling a function or setting a variable? Here's another way to do it perhaps, which sets a variable and removes the offending chars at the end - no extra math or if checks needed.
<?php
$tagoutput = '';
if ($tags) {
foreach ($tags as $tag)
$tagoutput .= '' . $tag->name . ', ';
$tagoutput = rtrim($tagoutput, ', ');
}
echo $tagoutput;
?>
You can do it the other way around (remove it from the first one). If your array is numeric you can try something like this:
<?php if ($tags): ?>
<?php foreach ($tags as $key => $tag): ?>
<?php if ($key > 0): ?>,<?php endif ?>
<a href="<?php echo get_tag_link($tag); ?>">
<?php echo $tag->name; ?>
</a>
<?php endforeach ?>
<?php endif ?>
You can also try it using counter.
$values = array('value','value','value');
$count = count($values);
$i = 0;
foreach($values as $value){
$i++;
echo $value;
if($count > $i){
echo ', ';
}
}
Output: value, value, value
I'm trying to figure out how to get the current post ID from my main wp_query loop to work in the nested loop..
I've added my loops below with most HTML removed to make it cleaner to see.
I need to replace the "16" where it says "$currentID = 16;" in the nested loop with the actual current post ID from the main loop.
<?php $related_query = new WP_Query( 'post_type=post&posts_per_page=-1' ); ?>
<?php if( $related_query->have_posts() ): ?>
<?php while ( $related_query->have_posts() ) : $related_query->the_post(); ?>
<?php the_ID(); ?>
<?php the_time('F j, Y'); ?>
<?php the_category(); ?>
<?php echo get_edit_post_link(); ?>
<?php echo get_post_meta(get_the_ID(), 'cf_meta-desc', true); ?>
<?php echo get_post_meta(get_the_ID(), 'cf_xray', true); ?>
<?php the_tags(); ?>
<ul>
<h4>Recommended Articles</h4>
<?php
$related_cfs = get_post_meta( get_the_ID(), 'cf_related' );
foreach($related_cfs as $related_cf) {
echo '<li>';
echo '<span class="related-links__id">' .$related_cf. '</span>';
echo '<span class="related-links__title"><a target="_blank" href="' .get_permalink($related_cf). '">' .get_the_title($related_cf). '</a></span>';
echo '<span class="related-links__edit"><a target="_blank" href="' .get_edit_post_link($related_cf). '">edit</a></span>';
echo '</li>';
} ?>
</ul>
<?php global $post;$backup=$post; //saves main query data before calling nested query ?>
<!-- BEGIN NESTED LOOP -->
<?php $referral_query = new WP_Query( 'meta_key=cf_related&posts_per_page=-1' ); ?>
<ol>
<h4 class="referring-links__header">Linkbacks (<?php

$count = $wpdb->get_var($sql);
echo "$count";
?>)
</h4>
<?php while ( $referral_query->have_posts() ) : $referral_query->the_post(); ?>
<?php

$arrayCFrelated = get_post_custom_values('cf_related');

<?php endwhile; ?>
<?php else: ?>
<p class="center">Nothing found.</p>
<?php endif; ?>
<?php wp_reset_query(); ?>
The code you posted is very hard to read because it is all nested and distributed between opening and closing php tags.
First of all - You should consider to get familiar with functions and objects as an alternative to nest everything within the same loop. This will also help other developers who work with you to understand your code.
As for your problem. Try using other types of loops to get indices within the loop. For example:
for ($i1=0; $i1 < count($yourarray); $i1++) {
// ...
echo "index: $i1 <br />";
echo "value: {$yourarray[$i1]}";
}
or
foreach ($array AS $idx => $value) {
// ...
echo "index: $idx <br />";
echo "value: $value";
}
I know this question is old but I run into the same issue recently.
If you have a main loop and want to get the ID (or any other data) of the current post to be used inside of a nested wp_query then use the global $post object.
Using 'get_the_id()' inside of the nested wp_query will return the id of the current post in the nested wp_query and not the main query
Example:
$post_id = $post->ID;
I´ve got the following code and when I paste the code to my page, I get a white page, can you guys help me?
PHP
<?php $strRendersettings = ($this->settings)? 'settings' : 'view'; ?><?php if (count($this->data)): ?>
<ul>
<?php
switch($_SERVER['HTTP_HOST'])
{
case ("www.domain.de"):
foreach ($this->data as $arrItem): ?>
<li class="new_doc_home"><a href=""; ?>" ><strong><?php echo $arrItem['text']['new_docs_titel']; ?>:</strong><br>
<p><?php echo $arrItem['text']['new_docs_Text']; ?></p></a>
</li>
<?php
break;
case ("www.domain.com"):
foreach ($this->data as $arrItem): ?>
<li class="new_doc_home"><a href=""; ?>" ><strong><?php echo $arrItem['text']['new_docs_titel']; ?>:</strong><br>
<p><?php echo $arrItem['text']['new_docs_Text']; ?></p></a>
</li>
<?php
break;
case ("www.domain.fr"):
foreach ($this->data as $arrItem): ?>
<li class="new_doc_home"><a href=""; ?>" ><strong><?php echo $arrItem['text']['new_docs_titel']; ?>:</strong><br>

</li>
<?php
break;
}
?>
<?php endforeach; ?>
</ul>
<?php else: ?>
<?php endif; ?>
I need the code because of some different top level domains.
Thanks :)
The porblem is that you never end you foreach loops.
You should end each foreach: loop with endforeach;. Now you have 3 loops and only one closing endforeach;
For example this code works without a problem:
<?php
$array = [1=>2, 3=> 4];
$array2 = [5=>6,7=>8];
foreach ($array as $k => $v):
foreach ($array2 as $i => $j):
echo $i.' '.$j."<br />";
endforeach;
endforeach;
while the following doesn't:
<?php
$array = [1=>2, 3=> 4];
$array2 = [5=>6,7=>8];
foreach ($array as $k => $v):
foreach ($array2 as $i => $j):
echo $i.' '.$j."<br />";
//endforeach;
endforeach;
I advice you also to add at the beginning of your PHP file:
<?php
error_reporting(E_ALL);
ini_set('display_errors','1');
to have all warnings and error displayed. Of course on production you should disable error reporting
It looks like you're breaking the foreach loop with the break of the switch. You should end the foreach inside each case of the switch.
See you PHP error log for error messages. When there is a parse error, the page is shown blank, and the error message goes to the PHP error log.
In your code, <?php endforeach; ?> appears to be outside the switch. I guess each foreach should have its own endforeach before the switch's break.
Correct me if I'm wrong, but you are doing the exact same thing for each of the three scenarios. I would alter my code to this:
<?php $strRendersettings = ($this->settings)? 'settings' : 'view'; ?>
<?php if (count($this->data)): ?>
<ul>
<?php
switch($_SERVER['HTTP_HOST'])
{
case "www.domain.de":
case "www.domain.com":
case "www.domain.fr":
foreach ($this->data as $arrItem): ?>
<li class="new_doc_home">
<a href="">
<strong>
<?php echo $arrItem['text']['new_docs_titel']; ?>:
</strong><br>
<p>
<?php echo $arrItem['text']['new_docs_Text']; ?>
</p>
</a>
</li>
<?php
endforeach;
break;
}?>
</ul>
You need to add endforeach statement before every break statement. Add that and your error will get sloved.
Hope this help :)
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; ?>
