What i did wrong?
Build array after query:
$arr = array();
while($r = $stmt->fetch(PDO::FETCH_ASSOC)) {
$arr[$r['team1']][$r['stadium']] = array($r['coach'] => $r['age']);
$arr[$r['team2']][$r['stadium']] = array($r['coach'] => $r['age']);
}
Showing data, HOW CAN i Put team 1 and team2? example:
<?php foreach($arr as $team => $stadiums): ?>
<div><?php echo $team;?> AND <?php echo $team;?></div> //----- HERE I NEED PUT TEAM 1 AND TEAM 2
<?php foreach($stadiums as $stadium => $coaches): ?>
<?php foreach($coaches as $choach => $ages): ?>
<?php foreach($stadiums as $stadium): ?>
<div><?php echo $stadium;?></div>
<?php endforeach; ?>
<?php endforeach; ?>
<?php endforeach; ?>
<?php endforeach; ?>

I've got a table called tickets. The Tickets table has 4 columns: user_id, ticket_id, subject, message. I want to loop the ticket_id and subject of the logged in user. I want to echo it with foreach, but I cant get it to work. This is what I've got:
Query:
$showTheTickets = array();
$user_id = $_SESSION['user_id'];
$getTickets = mysqli_query($mysqli,"SELECT * FROM tickets WHERE user_id = '$user_id'") OR die (mysqli_error($mysqli));
while($row = mysqli_fetch_assoc($getTickets)){
$showTicketID = $row['ticket_id'];
$showTicketSubject = $row['subject'];
}
Code in the page:
<?php foreach ($showTheTickets as $showTheTickets): ?>
<div class="preview">
<?php echo $showTicketID ?>
<?php echo $showTicketSubject ?>
</div>
<?php endforeach; ?>
Anyones willing to help me? Thanks.
Try this:
$showTheTickets = array();
$user_id = $_SESSION['user_id'];
$getTickets = mysqli_query($mysqli,"SELECT * FROM tickets WHERE user_id = $user_id") OR die (mysqli_error($mysqli));
while($row = mysqli_fetch_array($getTickets)){
$row = array( 'ticket_id' => $row['ticket_id'], 'subject' => $row['subject'] );
$showTheTickets[] = $row;
}
And then:
<?php foreach ($showTheTickets as $stt): ?>
<div class="preview">
<?php echo $stt['ticket_id'] ?>
<?php echo $stt['subject'] ?>
</div>
<?php endforeach; ?>
Hope it helps...
You are overwriting the values you get from the query and your $showTheTickets array remains empty.
You probably want something like:
$showTheTickets = array();
while($row = mysqli_fetch_assoc($getTickets)){
$showTheTickets[$row['ticket_id']] = $row['subject'];
}
and:
<?php foreach ($showTheTickets as $id => $subject): ?>
<div class="preview">
<?php echo $id; ?>
<?php echo $subject; ?>
</div>
<?php endforeach; ?>
Why not simply
while($row = mysqli_fetch_assoc($getTickets)){
?><div class="preview"><?
echo $row['ticket_id'];
echo $row['subject'];
?></div><?
}
you have to save $showTicketID and $showTicketSubject in a array (could be the same array or 2 arrays) and then in the view show the arrays, like this:
while($row = mysqli_fetch_assoc($getTickets)){
$array[$row['ticket_id']] = $row['subject'];
}
and the view:
<?php foreach ($showTheTickets as $ticketid => $ticketsubject): ?>
<div class="preview">
<?php echo $ticketid ?>
<?php echo $ticketsubject ?>
</div>
<?php endforeach; ?>
In my controller I have this Code to loop through database and return the data
$faultgroup = $this->booking_model->Get_Fault_Group_Display($grouptype);
$data['Get_Fault_Group_Display'] = $faultgroup; $getresults = array();
$data['get_fault_group_data'] = array();
foreach ($faultgroup as $key ) {
$show = $key->Showgroup;
$getresults = $this->booking_model->get_fault_group_data($grouptype,$show);
$data['get_fault_group_data'] = $getresults ;
}
In my View i have this Code to loop through each record with the specific grouptype and display record (to_do_item) from database that match that grouptype
<?php if ( ! is_null($Get_Fault_Group_Display)): ?>
<?php if (count($Get_Fault_Group_Display)): ?>
<?php foreach ($Get_Fault_Group_Display as $result): ?>
<?php echo $result->Showgroup; ?>
<?php foreach ($get_fault_group_data as $key) :?>
<?php echo $key->to_do_item; ?>
<?php endforeach ?>
<?php endforeach ?>
<?php else: ?>
<?php endif ?>
My problem is only the last row is shown on all the grouptypes because the loop keeps overiding $data['get_fault_group_data'] with the new $getresults
Shouldn't you use the $data['get_fault_group_data'] as an array?
Controler:
$data['get_fault_group_data'][$key] = $getresults ;
View:
<?php if ( ! is_null($Get_Fault_Group_Display)): ?>
<?php if (count($Get_Fault_Group_Display)): ?>
<?php foreach ($Get_Fault_Group_Display as $i => $result): ?>
<?php echo $result->Showgroup; ?>
<?php foreach ($get_fault_group_data[$i] as $key) :?>
<?php echo $key->to_do_item; ?>
<?php endforeach ?>
<?php endforeach ?>
<?php else: ?>
<?php endif ?>
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>';
}
Im looking to echo the value of my array key out into the view for this controller. I cant quite figure it out. So for the first feed I want to echo mmafighting into the of the view. Then it would loop through the rest.
Here is my controller code:
function index()
{
$this->load->library('simplepie');
$feeds = array('mmafighting' => 'http://www.mmafighting.com/rss/current',
'bbc' => 'http://feeds.bbci.co.uk/news/world/us_and_canada/rss.xml',
'bloodyelbow' => 'http://www.bloodyelbow.com/rss',
'ufc' => 'http://www.ufc.com/rss/news',
'hackernews' => 'http://news.ycombinator.com/rss',
'msnbc' => 'http://www.msn.com/rss/news.aspx',
'msnbc2' => 'http://www.msn.com/rss/msnmoney.aspx',
'msnbc3' => 'http://www.msn.com/rss/msnshopping_top.aspx'
);
foreach ($feeds as $site=>$url)
{
$data['feed'][$site] = new SimplePie();
$data['feed'][$site]->set_feed_url($url);
$data['feed'][$site]->set_cache_location(APPPATH.'cache');
$data['feed'][$site]->set_cache_duration(300);
$data['feed'][$site]->init();
$data['feed'][$site]->handle_content_type();
}
$this->load->view('feedsview', $data);
}
Here is my view code:
<?php
$feedCount = 0;
$rowCount = 0;
?>
<?php foreach ($feed as $site): ?>
<?php if ($site->data): ?>
<div class="feed">
<h2><?php // echo original array key here ?></h2>
<ul>
<?php $items = $site->get_items(0, 5); ?>
<?php foreach ($items as $item): ?>
<li><?php echo $item->get_title(); ?></li>
<?php endforeach; ?>
</ul>
</div>
<?php endif; ?>
<?php $feedCount++; ?>
<?php if ($feedCount === 3) {
echo '<div style="clear:both;"> </div>';
$feedCount = 0;
$rowCount++;
if ($rowCount === 2) {
echo '<div style="width:1000px; margin-bottom:20px;height:100px; border:1px solid #252525; float:left;">images</div>';
}
} ?>
<?php endforeach; ?>
I'm not sure i understand but what about doing this :
<?php foreach ($feed as $key => $site): ?>
<?php if ($site->data): ?>
<div class="feed">
<h2><?php echo $key ?></h2>
<ul>
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; ?>
