I have a result like this:
Using foreach loop i can get the output like this:
<ul>
<li>1 group1 group1_title group1_link 2</li>
<li>2 group1 group1_title group1_link 1</li>
<li>3 group2 group2_title group2_link 2</li>
<li>4 group2 group2_title group2_link 1</li>
<li>5 group3 group3_title group3_link 2</li>
<li>6 group3 group3_title group3_link 1</li>
<li>7 group3 group3_title group3_link 2</li>
</ul>
But I need to make the result like this:
<ul data-group="1">
<li>1 group1 group1_title group1_link 2</li>
<li>2 group1 group1_title group1_link 1</li>
</ul>
<ul data-group="2">
<li>1 group2 group2_title group2_link 2</li>
<li>2 group2 group2_title group2_link 1</li>
</ul>
<ul data-group="3">
<li>1 group3 group3_title group3_link 2</li>
<li>2 group3 group3_title group3_link 1</li>
<li>3 group3 group3_title group3_link 2</li>
</ul>
Here is my simple php code
if ($getlinks->num_rows() > 0)
{
$x = 0;
foreach ($getlinks->result() as $group)
{
$x++;
echo '<ul group="'.$x.'">';
echo '<li>'.$group->id.' - '.$group->group.' - '.$group->title.' - '.$group->link.' - '.$group->value.'</li>';
echo '</ul>';
}
}
Update:
using bellow code i can group by value but i need make something like this by key not value
$people = array("Peter", "Peter", "Joe", "Glenn", "Cleveland");
//echo current($people) . "<br>";
//echo end($people);
foreach ($people as $p){
echo ($p);
if (current($people) !== next($people)){
echo " bah<br>";
}
}```
You need to track when the group changes:
if ($getlinks->num_rows() > 0)
{
$x = 0;
$prev_group = null;
foreach ($getlinks->result() as $group)
{
// I am assuming $group->id can't be null for an actual group
if ( $group->id !== $prev_group ) {
if ( $x > 0 ) {
// Close previous group
echo '</ul>';
}
echo '<ul group="'.$group->id.'">';
$x = 0;
$prev_group = $group->id;
}
$x++;
echo '<li>'$x.' - '.$group->id.' - '.$group->group.' - '.$group->title.' - '.$group->link.' - '.$group->value.'</li>';
}
if ( $x > 0 ) {
// Close last group
echo '</ul>';
}
}
I'm not clear what your data structures are and if it's $group->id or $group->group that should be compared, but you see the idea I hope.

There was a question raised by Log1x about Comparing JSON after foreach loop for a Discord Channel Viewer
This is the link: Comparing JSON after foreach loop In his viewer he wanted to output something like:
<ul>
<li>Channel 1
<ul>
<li>User 1</li>
<li>User 2</li>
</ul>
</li>
<li>Channel 2</li>
<li>Channel 3
<ul>
<li>User 3</li>
</ul>
</li>
</ul>
There was an excellent answer on how to do this, from Mojtaba which was:
$discord = json_decode(file_get_contents('https://discordapp.com/api/servers/'.$id.'/widget.json'));
if ($discord->channels) {
usort($discord->channels, function($a, $b) {
return $a->position > $b->position ? 1 : -1;
});
echo '<ul>';
foreach ($discord->members as $member) {
if (!empty($member->channel_id)) {
$channel_members[$member->channel_id][] = $member->username;
}
}
foreach ($discord->channels as $channel) {
echo "<li>{$channel->name}";
if (!empty($channel_members[$channel->id])) {
echo '<ul>';
foreach ($channel_members[$channel->id] as $username) {
echo "<li>$username</li>";
}
echo '</ul>';
}
echo "</li>";
}
echo '</ul>';
}
I have already completed my viewer but you will be able to see from this screen-shot link that my available space is limited and taken up by too many empty channels. So I am interested to know if there is a way to hide channels that are empty i.e.
<ul>
<li>Channel 1
<ul>
<li>User 1</li>
<li>User 2</li>
</ul>
</li>
<li>Channel 3
<ul>
<li>User 3</li>
</ul>
</li>
</ul>
As I have said, my interest is also for a Discord Channel Viewer , so the above information from both Mojtaba and the first link are directly relevant to my code too.
Thanks in advance.
I think you should be able to just move your <li> tag inside the if.
foreach ($discord->channels as $channel) {
// outside the if, the channel shows even if it's empty
if (!empty($channel_members[$channel->id])) {
// inside the if, you'll only see the channel if it's not empty
echo "<li>{$channel->name}<ul>";
foreach ($channel_members[$channel->id] as $username) {
echo "<li>$username</li>";
}
echo '</ul></li>';
}
}
I want make menu with 2 levels sub menu. Eventually, the HTML should like the code below:
<ul>
<li>elektronikos prekes
<ul>
<li>dar kaskas
<ul>
<li>ka ka 2</li>
</ul>
</li>
<li>tranzistoriai
<ul>
<li>sub 1</li>
<li>tikri 1</li>
</ul>
</li>
</ul>
</li>
<li>kompiuteriai
<ul>
<li>nesiojami 8</li>
</ul>
</li>
</ul>
Here is my code:
$queryreg=mysql_query("select distinct a.meniu as meniu , b.sub as sub, c.sub2 as sub2,a.meniu_id as m_id, b.sub_id as s_id,
c.sub2_id as s_id2, count(distinct p.id) as pre
from meniu a
LEFT OUTER JOIN sub AS b ON ( a.meniu_id = b.meniu_id and b.rodyti='1' )
LEFT OUTER JOIN preke AS p ON ( b.sub = p.sub and a.meniu=p.meniu)
LEFT OUTER JOIN sub2 AS c ON ( b.sub_id = c.sub_id AND c.rodyti='1')
LEFT OUTER JOIN preke AS pr ON ( pr.sub2 = c.sub2 and pr.sub=b.sub and pr.meniu=a.meniu)
where a.rodyti='1' and a.meniu='elektronikos prekes' or a.meniu='kompiuteriai'
group by a.meniu, a.meniu_id, b.sub, b.sub_id, c.sub2, c.sub_id");
$AnkstesnisSub='';
$ankstesnisMeniu='';
$output = $ankstesnisMeniu.$AnkstesnisSub = '';
echo'<ul>';
while ($row = mysql_fetch_assoc ($queryreg))
{
if ($row['meniu'] != $ankstesnisMeniu )
{
if (!empty ($ankstesnisMeniu) )
{
$output .= " </ul></li></ul></li>";
}
$output .= '<li>' . $row['meniu'] . "<ul>";
$ankstesnisMeniu = $row['meniu'];
}
if ( $row['sub'] != $AnkstesnisSub)
{
if (!empty ($AnkstesnisSub))
{
$output .= "</ul></li>";
}
if($row['sub2']==NULL){$prekiu_kiekis = $row['pre'];}
elseif($row['sub2']!=NULL){$prekiu_kiekis ='';}
$output .= '<li>' . $row['sub'] . " $prekiu_kiekis<ul>";
$AnkstesnisSub = $row['sub'];
$prevID2 = $row['s_id'];
}
if($row['sub2']!=NULL){$prekiu_kiekis = $row['pre'];}
elseif($row['sub2']==NULL){$prekiu_kiekis ='';}
$output .= '<li>' . $row['sub2'] ." $prekiu_kiekis</li>";
$prevID3=$row['sub2'];
}
$output = '' . $output . "</ul></li></ul></li>";
echo"$output";
echo'</ul>';
But I get:
<ul>
<li>elektronikos prekes
<ul>
<li>dar kaskas
<ul>
<li>ka ka 2</li>
</ul>
</li>
<li>tranzistoriai
<ul>
<li>sub 1</li>
<li>tikri 1</li>
</ul>
</li>
</ul>
</li>
<li>kompiuteriai
<ul></ul>
</li>
<li>nesiojami 8
<ul>
<li></li>
</ul>
</li>
</ul>
</li></ul>
To the first menu item everything is fine, but the second wrong. maybe somebody can help me?
i think it's very complicated code, why not to separate this for 2 table?
top_menu => link_id, href, link_text, count_sub
sub_menu => link_id, parent_id, href, link_text, count_sub
the code for getting the menu:
$query = mysql_query("SELECT * FROM top_menu");
while ( $row = mysql_fetch_assoc($queryreg) )
{
echo '<li>' . $row['href'] . '</li>';
if( $row['subcount'] != 0 ) {
{ make query for the sub_menu and do more while... and in the while you can add more }
}
}
and so on.. it's more clean for my opinion.
Let's say I have an array containing these items:
$test = array(Item1, Item2, Item3, Item4, Item5, Item6, Item7, Item8, Item9);
How can I print this structure using for, or foreach?
<ul>
<li>
<ul>
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
<li>Item 4</li>
</ul>
</li>
<li>
<ul>
<li>Item 5</li>
<li>Item 6</li>
<li>Item 7</li>
<li>Item 8</li>
</ul>
</li>
<li>
<ul>
<li>Item 9</li>
</ul>
</li>
</ul>
You could split the array into chunks, using array_chunk():
$chunks = array_chunk($test, 4);
This will give you an array containing sub-arrays of 4 items each. You could then loop through these to create the list items:
<ul>
<?php foreach ($chunks as $chunk): ?>
<li>
<ul>
<?php foreach ($chunk as $item): ?>
<li><?php echo htmlspecialchars($item) ?></li>
<?php endforeach ?>
</ul>
</li>
<?php endforeach ?>
</ul>
use array_chunk to split your values
$test = array('Item1','Item2','Item3','Item4','Item5','Item6','Item7','Item8','Item9');
$chunk = array_chunk($test, 4);
echo '<ul>';
foreach($chunk as $pieces) {
echo '<li>';
echo '<ul>';
foreach($pieces as $item) {
echo '<li>'.$item.'</li>';
}
echo '</ul>';
echo '</li>';
}
echo '</ul>';
Try this
<?php
$test = array(Item1, Item2, Item3, Item4, Item5, Item6, Item7, Item8, Item9);
$ChunkedTestarray = array_chunk($test, 4);
echo "<ul>";
foreach($ChunkedTestarray as $Data) {
echo "<li><ul>";
for ($i = 0; $i <= count($Data)-1;) {
echo "<li>".$Data[$i]."</li>";
$i++;
}
echo "</ul></li>";
}
echo "</ul>";
?>
I want to add my ul & li every two loop.. Example
<?php while ( $loop->have_posts() ) : $loop->the_post(); ?>
<ul>
<li> <?php the_title() ?> - <?php the_content() ?></li>
</ul>
<?php endwhile; ?>
Let's say I have 4 posts and I want the result should be like this
<ul>
<li>Title 1 - content 1</li>
<li>Title 2 - content 2</li>
</ul>
<ul>
<li>Title 3 - content 3</li>
<li>Title 4 - content 4</li>
</ul>
add a counter variable (start =0) that increments at the end of each pass through the loop. Then at the beginning of each pass, test if($counter%2==0){ echo "</ul><ul>";}and put the first <ul> and last </ul> outside of the loop
I would do something like this:
for($i = 0; $i < $numberOfUls; $i++)
{
$result = '<ul>';
for($j = 0; $j < $numberOfLis; $j++)
{
$result .= '<li>Title content</li>'; // Perhaps an array with the whole list $listContent[$i][$j];
}
$result .= '</ul>';
}
echo $result;
I have the following HTML output;
<ul>
<li>Test 1</li>
<li>Test 2.</li>
<li>Test 3</li>
<li>Test 4</li>
<li>Test 5</li>
<li>Test 6</li>
<li>Test 7</li>
</ul>
What I need to do, is display the same HTML, but with only the first 4 <li> tags, i.e.
<ul>
<li>Test 1</li>
<li>Test 2.</li>
<li>Test 3</li>
<li>Test 4</li>
</ul>
Is there an easy way I can do this in PHP?
Thanks
EDIT:
The data is coming from:
$data = $product->getDescription();
It is stored in the DB as the HTML content, I am currently displaying it using the above code;
Thanks
Umm yes..
Depending on where the data is coming from, I am going to assume it is a db of some sort and you have it in an array():
$databasevalue = array(); //stuff from database goes here / dragons
echo "<ul>";
for ( $counter = 0; $counter < 4; $counter ++) {
echo "<li>".$databasevalue[$counter]."</li>";
}
echo "</ul>";
Can't offer more without better question details.
How is data coming from ?
If this data comes from an array you can slice it with array_slice function
$list = array_slice($input, 0, 4);
// $list now only having first 4 item.
<?php
echo '<ul>' . PHP_EOL;
for ($i = 1; $i <= 4; $i++)
{
echo '<li>' . $i . '</li>' . PHP_EOL;
}
echo '<ul>' . PHP_EOL;
?>
Outputs:
<ul>
<li>1</li>
<li>2</li>
<li>3</li>
<li>4</li>
<ul>
Someone else answered with a good one (requires SimpleXMLElement, PHP5) but has been deleted:
<?php
$data = '<ul>
<li>Test 1</li>
<li>Test 2.</li>
<li>Test 3</li>
<li>Test 4</li>
<li>Test 5</li>
<li>Test 6</li>
<li>Test 7</li>
</ul>';
$ul = new SimpleXMLElement($data);
$li = $ul->li;
echo '<ul>'.PHP_EOL;
for($i = 0 ; $i < 4 ; $i++)
{
echo '<li>'.$li[$i].'</li>'.PHP_EOL;
}
echo '</ul>'.PHP_EOL;
?>
if you're using database, you should use "LIMIT" in your SQL, otherwise array_slice will do the job.
don't forget: documentation is your best friend (especially in php)
