I am having trouble figuring out how to write this code.
I have 1000 name db entries and I need to echo the results in sets of 4.
So the set # counts per each 4 entries until end of data.
How can I do this with php?
My result should look like this:
<div id="set-1">
<div>Name1</div>
<div>Name2</div>
<div>Name3</div>
<div>Name4</div>
</div>
<div id="set-2">
<div>Name5</div>
<div>Name6</div>
<div>Name7</div>
<div>Name8</div>
</div>
//and so on......
I would assume that your returned vlaues from your DB are in an array. I made a mock array just to mimick an array with 1000 entries.
<?php
$mockNameArray = array();
for ($i = 0; $i < 1000; $i++)
{
$mockNameArray[$i] = "Name" . $i;
}
?>
Since you have a set number returned from your DB it is easy to run a for loop instead of a foreach loop. I would do something like this.
<?php for ($i = 0, $x = 1; $i < 1000, $x < 251; $i++, $x++): ?>
<div id="set-<?php echo $x; ?>">
<div><?php echo $mockNameArray[$i]; $i++; ?></div>
<div><?php echo $mockNameArray[$i]; $i++; ?></div>
<div><?php echo $mockNameArray[$i]; $i++; ?></div>
<div><?php echo $mockNameArray[$i]; ?></div>
</div>
<p>
<?php endfor; ?>

I have a repeated row which have 5 columns. I want when every time row is looped column data is looped number but continues after every loop. Sample code:
$list = 0;
$list++;
for ($i = 0; $i < 5; $i++ ){
<div class="row">
<div class="col-2">$list</div>
<div class="col-2">$list</div>
<div class="col-2">$list</div>
<div class="col-2">$list</div>
<div class="col-2">$list</div>
</div>
}
Sample result what i want:
<div class="row">
<div class="col-2">1</div>
<div class="col-2">2</div>
...
<div class="col-2">5</div>
</div>
<div class="row">
<div class="col-2">6</div>
<div class="col-2">7</div>
...
<div class="col-2">10</div>
</div>
Any idea?
Use a nested loop to iterate through both your rows and columns while keeping a counter outside of the loop:
$counter = 1;
for ($rowCount = 1; $rowCount < 5; $rowCount++ ) {
echo '<div class="row">';
for ($colCount = 1; $colCount < 5; $colCount++ ) {
echo '<div class="col-2">', $counter, '</div>';
$counter++;
}
echo '</div>';
}
Fiddle: Live Demo
Simply increment the counter $list as part of the output
<?php
$list = 1;
for ($i = 0; $i < 5; $i++ ){
echo "<div class='row'>
<div class='col-2'>$list++</div>
<div class='col-2'>$list++</div>
<div class='col-2'>$list++</div>
<div class='col-2'>$list++</div>
<div class='col-2'>$list++</div>
</div>";
}
Using $list++ it will output the current value and then increment it by one ready for the next line etc etc
You can use two loops. One for how many rows($i) you have second one for iteration (1,2,3,4,5) ($list)
<html>
<body>
<?php
$list = 1;
for ($i = 0; $i < 5; $i++ ){
echo "<div class='row'>";
for ($list = 1; $list < 6 ; $list++) {
echo "<div class='col-2'>$list</div>";
}
echo "</div>";
}
?>
</body>

How do I merge two (for) in one code?
e.g first code
for ($i = 0, $n = count($options); $i < $n; $i ++) {}
and second code
for ($u = 'rel_article1'; $u <= 'rel_article5'; $u++)
here is oll code
<?php if ($display_poll) { ?>
<form action="<?php echo JRoute::_('index.php');?>" method="post" name="poll_vote_<?php echo $poll->id;?>" id="poll_vote_<?php echo $poll->id;?>">
<?php for ($i = 0, $n = count($options); $i < $n; $i ++) { ?>
<label for="mod_voteid<?php echo $options[$i]->id;?>" class="<?php echo $tabclass_arr[$tabcnt].$params->get('moduleclass_sfx'); ?>" style="display:block; padding:2px;">
<input type="radio" name="voteid" id="mod_voteid<?php echo $options[$i]->id;?>" value="<?php echo $options[$i]->id;?>" alt="<?php echo $options[$i]->id;?>" <?php echo $disabled; ?> />
<?php echo $options[$i]->text; ?> <?php for ($u = 'rel_article1'; $u <= 'rel_article5'; $u++) { ?>
<a href="<?php echo $params->get($u); ?>" onClick="return popup(this, 'notes')">
<img src="/images/stories/add.png" alt="play"></a>
<?php
} ?
I want in one poll show onle play button
now shows this
here is my xml code:
You don't really need that second for. You already have an index with $i from your first loop. (Except that it starts from 0 instead of 1, but you can easily get it working)
Remove the second for, and try this :
// echo $params->get($u);
echo $params->get('rel_article' . ($i + 1));
I created the available seat with a for loop below:
<?php
$seats = 7;
for ($i=1; $i <= $seats; $i++) {
?>
<div class='col-xs-6'>
<div class='well text-center' id='<?php echo $i ?>'>
Seat No: <?php echo $i ?>
</div>
</div>
<?php
}
?>
And I want to add a booked class if the $i variable matches with the $k variables which taken from the booked seat array elements below:
$booked_seat = array('1','4','5','6','7');
the result:
Array
(
[0] => 1
[1] => 4
[2] => 5
[3] => 6
[4] => 7
)
So I did this:
<?php
$seats = 7;
for ($i=1; $i <= $seats; $i++) {
?>
<div class='col-xs-6'>
<div class='well text-center <?php echo ($i == $booked_seat[$i-1]) ? 'booked' : '' ?>' id='<?php echo $i ?>'>
Seat No: <?php echo $i ?>
</div>
</div>
<?php
}
?>
And i get the offset Error because the $booked_seat is not much as the $seats loop, how to limit the loop so it will not offset?
Thank you before
Try this:
$seats = 7;
for ($i=1; $i <= $seats; $i++) {
?>
<div class='col-xs-6'>
<div class='well text-center <?php echo (in_array($i, $booked_seat)) ? "booked" : "" ?>' id='<?php echo $i ?>'>
Seat No: <?php echo $i ?>
</div>
</div>
<?php
}
?>
warning: code is untested.
You could always flip the $booked_seat array, then test for the existence of the array element using isset(). Something like this:
<?php
$seats = 7;
$booked_seat = array('1','4','5','6','7');
$booked_a = array_flip($booked_seat);
for ($i=1; $i <= $seats; $i++) {
printf("seat: %d%s\n", $i, isset($booked_a[$i]) ? " booked" : "");
}
(This was my test, you can add your HTML to suit.)
Example: http://3v4l.org/5npsm
You should use the method sizeof().
So:
$num_seats = sizeof($seats);
Then a for loop with this.
for($i = 0; $i < $num_seats; $i++){
//code
}
At the moment, with the code from below, I have the data shown like this:
http://img27.imageshack.us/img27/8083/29769986.jpg
but I want it to be shown like this:
http://img259.imageshack.us/img259/3233/24033830.jpg
The code for the data shown, as it is on the first image, is:
<div id="content">
<?php foreach ($categories as $category) { ?>
<div class="manufacturer-list">
<div class="manufacturer-heading"><?php echo $category['name']; ?><a id="<?php echo $category['name']; ?>"></a></div>
<div class="manufacturer-content">
<?php if ($category['manufacturer']) { ?>
<?php for ($i = 0; $i < count($category['manufacturer']);) { ?>
<ul>
<?php $j = $i + ceil(count($category['manufacturer']) / 4); ?>
<?php for (; $i < $j; $i++) { ?>
<?php if (isset($category['manufacturer'][$i])) { ?>
<li><?php echo $category['manufacturer'][$i]['name']; ?></li>
<?php } ?>
<?php } ?>
</ul>
<?php } ?>
<?php } ?>
</div>
</div>
<?php } ?>
</div>
I order to get the "Hewlett-Packard" text under the "HTC" text, I've changed the "/ 4" into "/ 1", but I have no idea how to make the data to be shown into three columns (like on the second picture), instead of one, as it is now (as shown on the first picture).
Thanks in advance.
EDIT: What I actually need, is to count and to do the calculation on this code:
<?php foreach ($categories as $category) { ?>
.
.
.
<?php } ?>
So it needs to count the number of categoris, do the calculations, and present the code between into three columns.
Try this one.
<div id="content">
<div class="content-column">
<?php
$cols = 3; // Change to columns needed.
$catcount = count($categories);
$catpercol = ceil($catcount / $cols);
$c = 0;
foreach ($categories as $category) {
if ( $c == $catpercol ) {
$c = 0;
print "</div><div class='content-column'>";
}
?>
<div class="manufacturer-list">
<div class="manufacturer-heading"><?php echo $category['name']; ?><a id="<?php echo $category['name']; ?>"></a></div>
<div class="manufacturer-content">
<?php if ($category['manufacturer']) { ?>
<?php for ($i = 0; $i < count($category['manufacturer']);) { ?>
<ul>
<?php $j = $i + ceil(count($category['manufacturer']) / 4); ?>
<?php for (; $i < $j; $i++) { ?>
<?php if (isset($category['manufacturer'][$i])) { ?>
<li><?php echo $category['manufacturer'][$i]['name']; ?></li>
<?php } ?>
<?php } ?>
</ul>
<?php } ?>
<?php } ?>
</div>
</div>
<?php $c++; } ?>
</div>
</div>
Add .content-column { float: left; width: 33.33333%; } to your CSS.
Details:
$cols = 3; enables you to set the desired number of columns (note: you might need to change CSS accordingly).
$catcount = count($categories); gives you the total number of categories about to be rendered.
$catpercol = ceil($catcount / $cols); divides that total number evenly into the required number of columns with the last column having eventually less items than the others.
$c = 0; is your counter. It increases at the end of the outer foreach loop.
Within the loop, $cis checked if it matches the $catpercol number and if so, the current parent div is closed and a new one created. You end up with as many parent divs as you need columns. Just add appropiate CSS to make them appear besides each other.
understand the following code that according to your requirement, the code just give the hint to achieve that you want according to your given screen shoot http://img259.imageshack.us/img259/3233/24033830.jpg
echo "<table>";
echo "<tr>";
$i = 1;
do{
// column range
$range = 3;
echo "<td>" . $i;
if( $i % $range == 0 ){
echo "</tr>";
echo "<tr>";
}
echo "</td>";
$i++;
}while( $i <= 10 );
echo "</tr>";
echo "</table>";
Hope this will help you
I think it is possible to create three column layout via html/css and without any change of your PHP code. Just use float:left; width: 33%. You can also use absolute value for width property because of margins and borders.
I have this php foreach loop
<?php $all_news = $this->db->query("Select * from news"); ?>
<div class="inner">
foreach($all_news as $key=>$news){?>
<div class="news <?php echo ($key%2==1)? 'odd': 'even'?>">
<div class="news_img">....<?php echo $news['title'] ?>
But the problem is the $all_news may have 20 results or so but the design only allows me to put for 4 news blocks in each inner div...is there a way make this happen so i have only 4 news divs in each inner div
<?php
$all_news = $this->db->query("Select * from news");
echo '<div class="inner">';
$c = count($all_news);
for($i = 0; $i < $c; $i++){
<div class="news <?php echo ($i%2==1)? 'odd': 'even'?>">
<div class="news_img">....<?php echo $news['title'] ?>
if($i % 4 == 3)
echo '</div><div class="inner">';
}
echo '</div>';
?>
Change your query to only return 4 rows:
SELECT * FROM news LIMIT 4
Alternatively you can change your for-loop.
for($i = 0; $i < min(4, count($all_news)); $i++)
{?>
<div class="news <?php echo ($i%2==1)? 'odd': 'even'?>">
<div class="news_img">....<?php echo $all_news[$i]['title'];
<?}
[edit]
See what you mean now. Create two loops:
<?
$index = 0;
while ($index < count($all_news))
{
$news = $all_news[$index];
?>Start outer div<?
for ($item = 0; $item < 5; $item++)
{
?>Inner div with news item <? echo $news['title'];
}
?>End outer div<?
$index++;
}
You could use two for loops:
<?php $all_news = $this->db->query("Select * from news"); ?>
<?php for($i = 0, $l = count($all_news); $i < $l; $i+=4): ?>
<div class="inner">
<?php for($j = $i; $j < $i+4; $j++): ?>
<div class="news <?php echo ($j%2==1)? 'odd': 'even'?>">
<div class="news_img">....<?php echo $all_news[$j]['title'] ?>
<?php endfor;?>
</div>
<?php endfor;?>
Another option would be array_chunk [docs].
The laziest way would be to just check whether or not you've already done four in the current div on the fly. If you have, close the current div and start a new one:
<div class="inner">
<?php
foreach ($all_news as $key => $news) {
if ($key % 2) {
$oddEven = 'odd';
} else {
$oddEven = 'even';
if ($key && $key % 4 === 0) {
echo '</div><div class="inner">';
}
}
echo "<div class=\"news $oddEven\">";
// ...
}
?>
</div>
Note that this assumes $all_news has an element at 0, so it makes sure that it doesn't close the first, empty div.
