Find last row in a foreach query - php

How could I find the last post and NOT put <hr> below it?
<?php foreach($db->query("SELECT * FROM news") as $row): ?>
<div class="NewsHeadline">
<div class="NewsDate"><?php echo $date; ?> - </div>
<div class="NewsTitle"><?php echo $title; ?></div>
</div>
<div class="NewsBody">
<?php echo $body; ?>
</div>
<hr>
<?php endforeach ?>

Set a counter equal to 1 which increments each round, and check if it is equal to the count() of the $query array returned. If it is, you are on the last round!
<?php
$counter = 1;
$total = count($db->query("SELECT * FROM news"));
?>
<?php foreach($db->query("SELECT * FROM news") as $row): ?>
<div class="NewsHeadline">
<div class="NewsDate"><?php echo $date; ?> - </div>
<div class="NewsTitle"><?php echo $title; ?></div>
</div>
<div class="NewsBody">
<?php echo $body; ?>
</div>
<?php if($counter != $total){
?>
<hr>
<?php
}
?>
<?php $counter++; ?>
<?php endforeach ?>

A solution would be to build an array and then use join :
<?php
$arr=array();
foreach($db->query("SELECT * FROM news") as $row):
$arr[] = '<div class="NewsHeadline"><div class="NewsDate">'.$date
.' - </div><div class="NewsTitle">'.$title'
.</div></div><div class="NewsBody">'.$body.'</div>';
endforeach
echo join("<hr>",$arr);
?>

You can convert to regular for loop and then compare $i to the size of your query result:
<?php
$news = $db->query("SELECT * FROM news");
for($i=0; $i<sizeof($news);$i++){ ?>
<div class="NewsHeadline">
<div class="NewsDate"><?php echo $date; ?> - </div>
<div class="NewsTitle"><?php echo $title; ?></div>
</div>
<div class="NewsBody">
<?php echo $body; ?>
</div>
<?php if(($i+1) < sizeof($news)) echo '<hr>'; ?>
<?php } ?>

If you get a count of the rows prior to the loop, you can check the count and avoid adding the HR.
$rows = $db->query("SELECT * FROM news");
$row_count = $rows.count();
$iter = 0;
foreach($rows as $row)
{
//...
if ($iter < $row_count)
{
// render hr
}
$iter++;
}
You could also go with a pure CSS approach:
div.containerClass:last-child hr { display:none; }
where "containerClass" would be whatever element your posted code sits inside of.

Use PHP foreach loop to display data in many html div tags

I have the following data and would like to display it in different containers in html.
Name Price Difference Signal
CA.PA 15.85 3.5609257364073 MACD
AZN.ST 896 3.4881049471963 MACD
AMGN 258.57 1.6391533819031 SMA 50/200
The containers are winner_1. As of right now the first winner_1 display the last Name from the above table.
How can I get it to say CA.PA in the first winner_1, and AZN.ST in the second winner_1, and AMGN in the last winner_1.
<div class="overview">
<h1>Winners</h1>
<div class="winner">
<?php
foreach ($res_winners_weekly as $r){
$name = $r["Name"];
$Price = $r['Price'];
$percent_diff = $r['Difference'];
$signal = $r['Signal'];
}
?>
<div class="winner_1">
<?php echo $name; ?>
</div>
<div class="winner_1">
<?php echo $name +1; ?>
</div>
<div class="winner_1">
</div>
</div>
</div>
The page can be seen here:
https://signal-invest.com/markets-today/
One option is generated div tags using php:
<div class="overview">
<h1>Winners</h1>
<div class="winner">
<?php
foreach ($res_winners_weekly as $r) {
$name = $r["Name"];
$Price = $r['Price'];
$percent_diff = $r['Difference'];
$signal = $r['Signal'];
echo "<div class='winner_1'>";
echo "<a href='#'>{$name}</a>";
echo "</div>";
}
?>
</div>
</div>
You should see following logic and try doing this way. Hopefully your problem will be resolved.
<div class = "overview">
<h1>Winners</h1>
<div class = "winner">
<?php
foreach ($res_winners_weekly as $r) {
$name = $r["Name"];
$Price = $r['Price'];
$percent_diff = $r['Difference'];
$signal = $r['Signal'];
echo "<div class='winner_1'><a href='#'> $name </a></div>";
}
?>
</div>
</div>

ACF / PHP Repeater count

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..

if else error message always shows else statement message

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';
}

While-loop: group two result on one div

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++;
}

processing list of items in sections

I want 3 item per div (the sample has a total of 7 items) like this:
<div>
<item/>
<item/>
<item/>
</div>
<div>
<item/>
<item/>
</div>
But I can't do
while($r = mysql_fetch_array($q){
?><item/><?
}
if(++$i%3==1){
//blabla:)
}
Because it incorrectly prints out
<div>
<item/>
<item/>
<item/>
</div>
<div>
<item/>
...
How do I correctly print out the items in blocks of 3?
You were most of the way there.
$result = mysql_query("SELECT ....");
$recordCounter = 0;
$record = mysql_fetch_assoc($result);
while ($record) {
if ($recordCounter % 3 == 0) {
?>
<div class="item-block">
<?php
}
?>
<div class="item"></div>
<?php
$record = mysql_fetch_assoc($result);
$recordCounter++;
if ($record === false || $recordCounter % 3 == 0) {
?>
</div>
<?php
}
}
mysql_free_result($result);
somewhat shortened :))
<div class="items">
<? $q = mysql_query("SELECT * FROM table ");
$i=1;
while($r = mysql_fetch_array($q))
{
?><item /><?
if($i%4==0){?></div><div class="item"><? }?>
<? $i++;
}?>
</div>
Here is another option, maybe there are too much php tags =)
<?php
$items = array(1,2,3,4,5,6,7,8);
$count = 1;
?>
<html>
<body>
<?php foreach ($items as $item) : ?>
<?php if ($count == 1) : ?>
<div>
<?php endif; ?>
<p><?php echo $item; ?></p>
<?php if ($count == 3) : ?>
</div>
<?php $count = 0; ?>
<?php endif; ?>
<?php $count++; ?>
<?php endforeach; ?>
</body>
</html>
