I have this code that's creating an extra empty div when there are extactly 3, 6, 9, etc items.
<?php
$i = 1;
echo '<div class="three-item-wrapper">';
if( have_rows('upcoming_stops_asia') ): while ( have_rows('upcoming_stops_asia') ) : the_row();
?>
<div class="item">Content</div>
<?php
if($i % 3 == 0) {echo '</div><div class="three-item-wrapper">';}
$i++; endif; endwhile; endif;
echo '</div>';
?>
I'm not sure how to fix it.
You are ending the current div and starting a new one when you get to a multiple of 3. If there are no more after that, then the div will of course be empty. One solution would be to accumulate the results and output them in a div only as required:
<?php
if( have_rows('upcoming_stops_asia') ) {
$results = [];
while ( have_rows('upcoming_stops_asia') ) {
the_row();
// Add to the collection of results
$results[] = '<div class="item">Content</div>';
if( count($results) == 3 ) {
// Output three results and reset
echo '<div class="three-item-wrapper">' . implode($results) . '</div>';
$results = [];
}
}
// Output any additional results; no div generated if there aren't any
if( !empty(results) ){
echo '<div class="three-item-wrapper">' . implode($results) . '</div>';
}
}
?>

With mysql left-join I have a result of 3 tables.
Every group of machine-types has special requirements. Some machine-types have the same requirements, some not.
My problem is, to list them grouped and clear adressable for css-styling. I want to show all groups - with its requirements - but the group as header only one time.
How can I output and place a closing div to the right position?
$lastDate = '';
while($r = $result_all->fetch(PDO::FETCH_OBJ)) {
$aktualisiert = $r->MTypID;
if ( $aktualisiert != $lastDate ){
echo '<div class="machine-type">'.$r->mtype'</div>';
echo '<div class="requirements">';
$lastDate = $aktualisiert;
}
//if ( $aktualisiert = $lastDate ){
echo $r->baustand." ";
//}
}//endwhile
Output should be like this (see *</div>*):
<div class="machine-type">Model 1</div><div class="requirements">Softwareupdate 2.4.0 Valve M4 Tube 20cm *</div>*
<div class="machine-type">Model 2</div><div class="requirements">Softwareupdate 2.4.0 *</div>*
You just need to close the div when $lastDate changes, but not when it is the first row in the output. So after
if ( $aktualisiert != $lastDate ){
add
if ( $lastDate != '' ) echo "</div>";
and then after your loop add
echo "</div>";
With adding of a separator (also a bit tricky), it's more useful.
Here the final code - maybe interesting to somebody...
$lastDate = '';
$separator ='+';
$space =' ';
while($r = $result_all->fetch(PDO::FETCH_OBJ)) {
$aktualisiert = $r->MTypID;
if ( $aktualisiert == $lastDate ) echo $separator.$space;
if ( $aktualisiert !== $lastDate ){
if ( $lastDate !== '' ) echo '</div>'; //<!-- end requirements 1/2 -->
echo '<div class="machine-type">'.htmlspecialchars($r->mtype)'</div>';;
echo '<div class="requirements">';
$lastDate = $aktualisiert;
}
echo htmlspecialchars($r->baustand).' ';
}//endwhile
echo '</div>'; //<!-- end requirements 2/2 -->
I have two html / css content. One of them floating left, the other one floating right.
I wanna pull data from my database, then putting them in a order. Left, right, left, right.
$services = pullservices();
while ($service = mysqli_fetch_object($services)){
for ($i=1; $i<=mysqli_num_rows($services); $i++) {
if ($i % 2 == 0): ?>
Left HTML Content
<?php else: ?>
Right HTML Content
<?php
endif;
}
}
?>
I have 6 items on db. But that code keeps looping one data for 6 times and it doing that for all the data on db.
That is the pullservices function.
function pullservices()
{
global $connect;
$products_query_string = "SELECT
id,
title_tr AS title,
text_tr,
short_text_tr,
image,
icon
FROM services WHERE status = 1 ORDER BY ordering , title_tr";
$products_query_run = mysqli_query($connect, $products_query_string);
return $products_query_run;
You can do this simply by using a flag.
(pseudo code):
$services = pullservices();
$flag=0;
while ($service = mysqli_fetch_object($services)){
if ($flag==0): ?>
Left HTML Content
<?php $flag=1; ?>
<?php else: ?>
Right HTML Content
<?php $flag=0; ?>
<?php
endif;
}
?>
One way you might be able to do this would be to split the data from the recordset and call it later in the html like this
$services = pullservices();
$i=0;
$data=array(
'left' =>array(),
'right' =>array()
);
while( $rs = mysqli_fetch_object( $services ) ){
$key = $i % 2 == 0 ? 'right' : 'left';
/* add the real data rather than placeholder data */
$data[ $key ][]=sprintf('%s HTML Content %d', ucfirst( $key ), $i );
$i++;
}
<div id='left'>
<?php
echo implode( PHP_EOL, $data['left'] );
?>
</div>
<div id='right'>
<?php
echo implode( PHP_EOL, $data['right'] );
?>
</div>
I have the following loop which brings in the title of each post onto my page
html
<?php
if (have_posts()) {
while (have_posts()) {
the_post();
echo '<div class="cell">'.get_the_title().'</div>';
} // end while
} // end if
?>
css
.cell {
display: inline-block;
margin: 0 10px;
}
I want to put a separator between each title/link brought in (not on the ends)
example output
link <div class="separate"></div>
link <div class="separate"></div> link
simple solution using additional flag variable $first
<?php
if ( have_posts() ) {
$first = true;
while ( have_posts() ) {
the_post();
if($first){
$first = false;
} else {
// echo separator
}
echo '<div class="cell">'.get_the_title().'</div>';
} // end while
} // end if
?>
You could put in a <hr> element at the end of your echo like this:
echo '<div class="cell">'.get_the_title().'</div><hr>';
You have to put a counter and compare the counter with posts per page to check if you have reached last post.
You can get posts per page from options table like this:
$default_posts_per_page = get_option( 'posts_per_page' );
Check if you have reached the last post, then don't print out the separator.
$counter = 1;
while ( have_posts() ) {
//your stuffs
if ($counter != $default_posts_per_page) {
//print separator
}
$counter++;
}
I am now working on a WordPress theme base with the Advanced Custom Fields plugin, And I want to show a <div> tag when the if statement is true. Here is my code:
<?php
$rows = get_field('classification');
$sort = get_sub_field('sort');
$row_count = count($rows);
for ($i = 1; $i <= $row_count; $i++)?>
<?php if ( $i==1 || $i%5==0) { ?>
<div class="bor"></div>
<h3 style="text-align:center">
<?php echo $sort; ?>
<a id="browser"></a></h3>
<div class="bor"></div>
<?php } ?>
or something like that
<?php
$rows = get_field('classification');
$fenlei = get_sub_field('fenlei');
$row_count = count($rows);
for ($i = 1; $i <= $row_count; $i++)?>
<?php if ( $i==1 || $i%5==0) { ?>
echo '<div class="bor"></div>';
echo '<h3 style="text-align:center">';
<?php echo $fenlei; ?>
echo '<a id="browser"></a></h3>';
<div class="bor"></div>
<?php } ?>
But the content of the div tag doesn't show.
Any reply is appreciated！Thank you very much.
some of your echo statement are out php tags. use this:
<?php
$rows = get_field('classification');
$fenlei = get_sub_field('fenlei');
$row_count = count($rows);
for ($i = 1; $i <= $row_count; $i++){
if ( $i==1 || $i%5==0) {
echo "<div class='bor'></div>
<h3 style='text-align:center'>".$fenlei."
<a id='browser'></a></h3>
<div class='bor'></div>";
}
}
?>
If you wanted to show the html in php, i suggest you use the below code.
<?php
$rows = get_field('classification');
$fenlei = get_sub_field('fenlei');
$row_count = count($rows);
for($i = 1; $i <= $row_count; $i++){
if ( $i==1 || $i%5==0) {
echo '>div class="bor"<>/div<';
echo '>h3 style="text-align:center"<';
echo $fenlei;
echo '>a id="browser"<>/a<>/h3<';
echo '>div class="bor"<>/div<';
}
}
?>
I'm guessing you're using an ACF Pro Repeater field. in this case you need to use the_row() which will set the sub-field's correct content. look at this edited example from the Docs:
<?php
// check if the repeater field has rows of data
if( have_rows('repeater_field_name') ):
// loop through the rows of data
while ( have_rows('repeater_field_name') ) : the_row();
// display a sub field value
the_sub_field('sub_field_name');
endwhile;
endif;
?>
so, I think your code should look more like:
<?php
if(have_rows('classification')):
while (have_rows('classification') ) : the_row();
// Your Code...
endwhile;
endif;
?>
And, I've learned recently you need to count the rows outside the while loop. othewise it won't catch the rows amount.
I'm running a while loop which is taking rows from mySQL and echo'ing them out. Pretty standard. However, there needs to be different HTML markup for the first item, next two items, then it continues as normal into the while loop.
Currently, my while loop looking something like this:
while( ( $row = mysql_fetch_object( $result ) ) !== false )
{
// Places ad based of predefined variable frequency
if ($ad == $adFrequency){
echo '<div class="one-advertisement-article clearfix">';
echo '<div class="grid_9 suffix_2"><img src="http://placehold.it/263x75/000000/ffffff"></div>';
echo '<div class="grid_1"><a class="navigate-right-icon ss-icon" href="#">navigateright</a></div>';
echo '</div>';
$ad = 0;
}
echo '<div class="one-news-article clearfix">';
if( $row->imagelibid )
{
$imageid = intval( $row->imagelibid );
$image_result = mysql_query( "SELECT * FROM imagelib WHERE id = {$imageid}", $db );
$image_row = mysql_fetch_object( $image_result );
$image_url = "http://www.#.com/slir/w280/imagelib/" . $image_row->id . "_" . $image_row->filename;
echo '<div class="grid_4"><img src="'.$image_url.'"></div>';
}
else {
echo '<div class="grid_4"><div class="news-placeholder"><span class="ss-icon">ellipsischat</span></div></div>';
}
echo '<div class="grid_7">';
echo '<h2>'.$row->title.'</h2>';
$published_date = date('D, d M Y', strtotime($row->datein));
echo '<p class="published-date">'.$published_date.'</p>';
echo '</div>';
echo '<div class="grid_1">';
echo '<div class="news-item-vertical-sep"> </div>';
echo '<p></p>';
echo '</div>';
echo '</div>';
$ad++;
}
This works fine, but I need to take the first three news items and use this:
echo ' <div class="one-news-featured-article clearfix">';
echo ' <div class="grid_12">';
if( $row->imagelibid )
{
$imageid = intval( $row->imagelibid );
$image_result = mysql_query( "SELECT * FROM imagelib WHERE id = {$imageid}", $db );
$image_row = mysql_fetch_object( $image_result );
$image_url = "http://www.#.com/slir/w280/imagelib/" . $image_row->id . "_" . $image_row->filename;
echo '<div class="large-featured-image-container"><img src="'.$image_url.'">/div>';
}
echo ' <div>';
echo ' <h2>'.$row->title.'</h2>';
echo ' </div>';
echo ' </div>';
echo ' </div>';
echo ' <div class="grid_6">';
Any help? Essentially, it needs to apply the second code to the first three items in the query, then follow through with the code included in the current while loop - like an offset I guess.
Thanks,
R
This is quite simple. I hope I understood your question correctly:
$i = 0;
while ( ( $row = mysql_fetch_object( $result ) ) !== false ) {
if ($i < 3) {
// First code
} else {
// Second code
}
$i += 1;
}
Firstly, you should avoid using any mysql_ functions as they are all deprecated and will be removed from future versions of PHP. I'd recommend using PDO instead. See this tutorial to get started.
Then, it'll simply be a case of doing something like this:
foreach($db->query($query) as $index => $row) {
if ($index < 3) {
// first 3 items
} else {
// other items
}
}
You can do it easaly with an simple counter and an if statement:
$count = 0;
while(fetching) {
if($count < 3) {
// items 1, 2 and 3
} else {
// do normal
}
$count++;
}
