I have the following code:
<?php $allCheckbox = get_field('sensor_types'); //Checked value from backend
$field_key = "field_60e546d470762"; //Get value using key
$post_id = get_the_ID();
$field = get_field_object($field_key, $post_id);?>
<?php foreach($field['choices'] as $lab => $val){
if(in_array($val, $allCheckbox)){
$enable = 'Yes';
} else {
$enable = 'No';
}?>
<div class="ct-div-block d-data-block c-columns-2-3">
<div class="ct-div-block"><?php echo $val; ?></div>
<div class="ct-div-block"><?php echo $enable ?></div>
</div>
<div class="d-seperator"></div>
<?php } ?>
I want to sort out the output to alphabetical order but as there is two output $val and $enable I am at confusion as to how i can use the Sort Function to solve this issue. The sort is dependent on $enable that is the ones with yes will come first then the ones with no

I have an array with products as objects in it. Each object contains a key = category_title
I have a foreach loop that generates products in Bootstrap rows with configurable columns, in my case $col=3.
What I need is to have a new row if a new category_title comes up.
I created an array to push all the category_titles in it and create a variable if it is a new category. But now I am stuck.
The foreach looks like this:
<?php foreach($productspercat as $product): ?>
<!-- Make sure product is enabled and visible #front end -->
<?php // if($product->enabled && $product->visibility):?>
<?php
$catnew = false;
$categorytitle = $product->category_title;
if(!in_array($categorytitle, $totalcategories, true)):?>
<?php array_push($totalcategories,$categorytitle );
$catnew=true;
?>
<?php endif;?>
<div class="j2store-products-row <?php echo 'row-'.$row; ?> row">
<?php endif;?>
<div class="col-sm-<?php echo round((12 / $col));?>">
<h2><?php echo $categorytitle; ;
var_dump($catnew);
?></h2>
test
</div>
<?php $counter++;
$firstrun = true; ?>
<?php if (($rowcount == $col) or ($counter == $total)) : ?>
</div>
<?php endif; ?>
<?php // endif; ?>
<?php endforeach;?>
So basically if a new category comes up, it should close the row and start a fresh row with a new column count.
appreciate any help!
If you don't want to page refresh then you can do that by using jQuery or Angular JS.
By jQuery you can add data by jquery prepend() function if you wanna add data in starting or append() function to add ending section.
<?php
// Arranged products by category title
$arrangedProducts = array()
foreach($productspercat as $product) {
if (!array_key_exists($product->category_title, $arrangedProducts)) {
$arrangedProducts[$product->category_title] = array();
}
$arrangedProducts[$product->category_title][] = $product;
}
// each category is a key and its value is an array with all its products
foreach ($arrangedProducts as $categoryTitle => $products) {
// you create a new row
// ....
foreach ($products as $product) {
// you display product information
}
// you end the row
}

I'm pulling comments from MySQL with PDO with a limit of 2 comments to show, yet the query does not retrieve the comments nor can I var_dump neither print_r since it does print anything. I believe it should be an issue with the query itself, thought it hasn't worked for countless hours so I figured I'd ask more experienced programmers.
There is no data outputted onto the page, I'm unsure whether It's an issue with the second_count variable or the post_iD variable.
1. Am I using the while loop correctly?
2. Better to use while loop or foreach?
3. Does var_dump and print_r function not work due to errors in the
query or in PHP.INI from what it seems?
Here is how I'm pulling the data with PDO.
PUBLIC FUNCTION Comments( $post_iD,$second_count ){
if($second_count){
$sth = $this->db->prepare("
SELECT C.com_id, C.uid_fk, C.comment, C.created, U.username, U.photo
FROM comments C, users U
WHERE U.status = '1'
AND C.uid_fk = U.uiD
AND C.msg_id_fk = :postiD
ORDER BY C.com_id ASC LIMIT :second, 2");
$sth->execute(array(':postiD' => $post_iD, ':second' => $second_count));
while( $row = $sth->fetchAll())
$data[] = $row;
if(!empty($data)){
return $data;
}
}
}
And here is how I'm trying to display the information on my page,
<?php
$commentsarray = $Wall->Comments( $post_iD, 0 );
$x=1;
if($x){
$comment_count = count($commentsarray);
$second_count = $comment_count-2;
if($comment_count>2){
?>
<div class="comment_ui" id="view<?php echo $post_iD; ?>">
View all<?php echo $comment_count; ?> comments
</div>
<?php
$commentsarray = $Wall->Comments( $post_iD, $second_count );
}
}
if( $commentsarray ){
foreach($commentsarray as $data){
$com_id = $data['com_id'];
$comment = tolink(htmlcode($data['comment'] ));
$time = $data['created'];
$mtime = date("g:i", $time);
$username = $data['username'];
$com_uid = $data['uid_fk'];
$photo = $data['photo'];
?>
<div class="stcommentbody" id="stcommentbody<?php echo $com_id; ?>">
<div class="stcommentimg">
<img src="<?php echo $photo;?>" class="small_face">
</div>
<div class="stcommenttext">
<?php if($uiD == $com_uid || $uiD == $post_iD ){ ?>
<a class="stcommentdelete" href="#" id="<?php echo $com_id;?>" title="Delete Comment"></a>
<?php } ?>
<div class="stmessage"><?php echo clear($comment); ?></div>
</div>
<div class="stime"><?php echo $mtime;?> — Like</div>
</div>
<?php
}
}
?>
1.Simply like this:
$data = $sth->fetchAll();
if(!empty($data) AND count($data) > 0){
return $data;
}
You don't need while to work with fetchAll.
2.I'ts better to use Exception in every your query then you can see if there is any error.
e.g
try
{
//your PDO stuffs here
}
catch (PDOException $e)
{
echo $e->getMessage();
}
I have the code below that is selecting a random set of questions from Wordpress.
<?php
$rows = get_field('step_by_step_test');
$row_count = count($rows);
$rand_rows = array();
$questions = get_field('select_number_of_questions');
for ($i = 0; $i < min($row_count, $questions); $i++) {
$r = rand(0, $row_count - 1);
while (array_search($r, $rand_rows) !== false) {
$r = rand(0, $row_count - 1);
}
$rand_rows[] = $r;
echo $rows[$r]['question'];
}
?>
I want to incorporate a bit of extra code (below), how can I make sure it's selecting the same random question?
<?php if(get_sub_field('answer_options')): ?>
<?php while(has_sub_field('answer_options')): ?>
<?php echo the_sub_field('answer'); ?>
<?php endwhile; ?>
<?php endif; ?>
Why dont you change your approach slightly?
<?php
$rows = get_field('step_by_step_test'); // Get the test
$question_count = get_field('select_number_of_questions'); // Get the number of questions
$rows = shuffle($rows); // Randomize your questions
$rows = array_slice($rows, $question_count); // Now set the array to only contain the number of questions you wanted
foreach ($rows as $row) {
echo $row['question']; // Show the question
if(get_sub_field('answer_options', $row['id'])) {
while(has_sub_field('answer_options', $row['id'])) {
echo the_sub_field('answer');
}
}
}
?>
I made the assumption that you can alter "get_sub_field" to include the ID of the question, so you can then include the ID in your "where" field of "answer_options". This will allow you to link the question.
I think that what you need is to set up the whole thing in a loop. query by custom field
Or you could store the ids of the questions you got above, an then, below, query for the answers for those specific posts.
Here's how I randomized my WordPress slider using the Advanced Custom Fields plugin + Royal Slider with a modified version of TheSwiftExchange's code above
<div id="full-width-slider" class="royalSlider heroSlider rsMinW">
<?php
/*
* Slider Repeater field shuffled
* http://stackoverflow.com/questions/12563116/incorporating-extra-loop-into-random-selection
*/
$rows = get_field('slider');
// For Debugging:
// echo "<pre>";
// var_dump($rows);
// echo "</pre>";
$quotes = get_field('slide_text'); // Get the number of images
shuffle($rows); // Randomize your slides
foreach ($rows as $row) {
$slideImageID = $row['slide_image'];
$slideImage = wp_get_attachment_image_src( $slideImageID, 'full' );
$slideText = $row['slide_text'];
?>
<div class="rsContent">
<div class="royalCaption">
<div class="royalCaptionInner">
<div class="infoBlock">
<?php if(!empty($slideText)) {
echo $slideText;
}; ?>
</div>
</div>
</div>
<img src="<?php echo $slideImage[0]; ?>" class="" />
</div><!-- /.rsContent -->
<?php } // end foreach ?>
</div><!-- /slider-wrap -->
I have a system where I rearrange navigational items.
It stores the new order in an array and then I use a for loop to go through the array and update the database.
<?php
$apageid = array();
$apagename = array();
$apageorder = array();
$q = "SELECT g.id, g.title, n.order FROM tbl_general g INNER JOIN tbl_navigation n ON n.pageid = g.id WHERE n.type = '$_SESSION[parent]' ORDER BY n.order";
$return = $database->query($q);
while($row=mysql_fetch_assoc($return)){
$apageid[] = $row['id'];
$apagename[] = $row['title'];
$apageorder[] = $row['order'];
}
$count = count($apageid);
$bpageid = array();
$bpageorder = array();
?>
<div class="form-holder">
<?php
//run through each page one at a time and update the order of the menu
mysql_data_seek( $return, 0 ); //reset the pointer to do the same query
$i = 0; //the count for saving the new configuration
while($row=mysql_fetch_assoc($return)){
$id = $row['id'];
$title = $row['title'];
$order = $row['order'];
?>
<div class="form-row">
<div class="form-label">
Page Name
</div>
<div class="form-field">
<select class="select-small" name="<?php echo $bpageid[$i]; ?>">
<?php
for($j=0; $j<$count; $j++){
if($apageid[$j] == $id) {
$selected = true;
} else {
$selected = false;
}
?>
<option value="<?php echo $apageid[$j]; ?>" <? echo ($selected == true) ? 'selected="selected"' : ''; ?>><?php echo $apagename[$j]; ?></option>
<?php
}
?>
</select>
<select class="select-small" name="<?php echo $bpageorder[$i]; ?>">
<?php
for($k=0; $k<$count; $k++){
if($apageorder[$k] == $order) {
$selected = true;
} else {
$selected = false;
}
?>
<option value="<?php echo $apageorder[$k]; ?>" <? echo ($selected == true) ? 'selected="selected"' : ''; ?>><?php echo $apageorder[$k]; ?></option>
<?php
}
?>
</select>
</div>
</div>
<?php
$i++;
}
?>
This first chunk of code is the menu where you can reorder items.
Initially it loads up the current select and allows you to change the ordering.
function reorderChildren($pageid, $pageorder){
global $database;
$count = count($pageid);
//run through each page one at a time and update the order of the menu
for($i=0; $i<$count; $i++){
//set a few variables
$pid = $pageid[$i];
$porder = $pageorder[$i];
echo "pid = $pid porder = $porder";
$q = "UPDATE tbl_navigation SET order = '$porder' WHERE pageid = '$pid' AND type = '$_SESSION[parent]'";
$database->query($q);
}
return 0;
}
The information then ends up being passed here and the problem appears to be the for loop is never executed.
Can anyone see why this would be?
It's not the naming used, I've checked them.
Am I storing information in the arrays correctly?
Can I make it clear that it's $bpageid and $bpageorder that are the arrays carrying the information forward.
Thanks!
Was a simple fix!
The problem was that the select name needed to be just name="bpageid[]" rather than what I listed above. Silly!
You have just initilized $bpageid = array(); at top after first while loop.No value is assigned
after that you using
<select class="select-small" name="<?php echo $bpageid[$i]; ?>">
but no value is in $bpageid[$i] so name of this select box is blank.
It might be problem. check this and do as required.
you could try to construct a json from the options of the select element store it to a hidden field or send ajax request to php script for processing , order could be made from a "weight" value 1,2,3 etc.... sort it with php and loop to display
I have a problem that concerns blog posts and displaying the tag words from another table.
I seem to be able to pull the info out of the tables fine, however when I try to display the posts and the tags, I get one tag per post. In other words if I have 7 tags for a post, I get 7 iteration's of that post each with one tag instead of 1 post with 7 tags.
My Controller ( do have a question about the $this->db->get(posts, tags) is that correct
$this->db->order_by('posts.id', 'DESC');
$where = "publish";
$this->db->where('status', $where);
$this->db->join('tags', 'tags.post_id = posts.id');
$this->db->limit('7');
$query = $this->db->get('posts', 'tags');
if($query->result())
$data = array();
{
$data['blog'] = $query->result();
}
$data['title'] = 'LemonRose';
$data['content'] = 'home/home_content';
$this->load->view('template1', $data);
The view.
$limit = 5; // how many posts should we show in full?
$i = 1; // count
foreach ($blog as $row):
$permalink = "http://".$_SERVER['HTTP_HOST'].$_SERVER['PHP_SELF'].$_SERVER['QUERY_STRING'];
$url = CompressURL ("$permalink");
$description = $row->title . $row->post;
$twittermsg = substr($description, 0, 110);
$twittermsg .= "...more " . $url;
if ($i < $limit) // we are under our limit
{ ?>
<div class="titlebox">
<div class="title"><? echo ucwords($row->title); ?></div>
<span><? echo $row->date, nbs(10), $row->author; ?></span>
</div>
<div class="clear"></div>
<? $str = str_word_count($row->post, 0);
if ($str >= 500) {
$row->post = html_entity_decode($row->post);
$row->post = $this->typography->auto_typography($row->post); // display?>
<div class="split"> <? echo $row->post = word_limiter($row->post, 480); ?>
<div class="tags"><? echo $row->tag; ?></div>*** These 3 lines seem to be where I am confused and getting the wrong display
<p><h3>More <?php echo anchor("main/blog_view/$row->id", ucwords($row->title)); ?> </h3></p>
<p>Trackback URL: <? echo base_url() . "trackbacks/track/$row->id"; ?></p>
<!-- tweet me -->
<?echo anchor("http://twitter.com/home?status=$twittermsg", 'Tweet'); ?>
This is my first attempt with join and I have very little experience getting the display with implode, if that is the right way to go.
Thank you in advance.
Try
<div class="tags"><? echo implode(', ', $row->tag); ?></div>
and remove the 2 rows before this one.
