How can I fetch an array in a row with two colums? - php

I am fetching with mysqli_fetch_array 100 rows and put in in a col-md-6.
But how can I trigger a line break after 50 rows so that I have two col-md-6 for a better view?
<div class="row">
<div class="col-md-6">
<?php
while($row = mysqli_fetch_array($sql)) {
echo '<input type="checkbox">$row['name']</input>';
}
?>
</div>
</div>

Simply use a counter.
<div class="row">
<div class="col-md-6">
<?php
$i = 1;
while($row = mysqli_fetch_array($sql)) {
echo '<input type="checkbox">', $row['name'], '</input>';
if($i++ == 50) echo '</div>', PHP_EOL, '<div class="col-md-6">', PHP_EOL;
}
?>
</div>
</div>
Note: $row['name'] must either be interpolated within echo-quotes or printed out.

New containing div after every 3 records

I would like to create a new containing <div> after 3 results, using PDO result loop.
For my self-study-project I have to made a product page with bootstrap and after every 3rd record I have to make a new row and show again 3 col-md-4's, etc, etc.
Now I have this as my code:
<div class="row">
<?php
while ($row = $stmt->fetch(PDO::FETCH_OBJ)) {
?>
<div class="col-md-4">
<div class="product">
<div class="title"><?php echo $row->pname ?></div>
<div class="img"><img
src="../product/img/<?php echo $row->pnumber ?>/<?php echo $row->pthumbnail ?>.jpg?$pop210x210$"/>
</div>
<div class="vijftien"></div>
<div class="deliver">Levertijd: <strong><?php echo $row->pdelivertime ?></strong></div>
<div class="vijf"></div>
<div class="other"></div>
<div class="row">
<div class="col-md-6">
<div class="price"><?php echo $row->pprice ?></div>
</div>
<div class="col-md-6">
<div class="order">
<button class="log_in" id="doLogin">Meer informatie</button>
</div>
</div>
</div>
</div>
</div>
<?php } ?>
</div>
I have visited and studied other questions but I do not really get the idea of how they are doing it and how I can implement the correct method into my code.
As tadman stated in the comment under your question. The best approach should use a modulus operator (%) with 3.
Place your separating condition at the start of each iteration. (Demo)
Like this:
$x=0; // I prefer to increment starting from zero.
// This way I can use the same method inside a foreach loop on
// zero-indexed arrays, leveraging the keys, and omit the `++` line.
echo "<div class=\"row\">";
foreach($rows as $row){
if($x!=0 && $x%3==0){ // if not first iteration and iteration divided by 3 has no remainder...
echo "</div>\n<div class='row'>";
}
echo "<div>$row</div>";
++$x;
}
echo "</div>";
This will create:
<div class="row"><div>one</div><div>two</div><div>three</div></div>
<div class='row'><div>four</div><div>five</div><div>six</div></div>
Late Edit, here are a couple of other methods for similar situations which will provide the same result:
foreach(array_chunk($rows,3) as $a){
echo "<div class=\"row\"><div>",implode('</div><div>',$a),"</div></div>\n";
}
or
foreach ($rows as $i=>$v){
if($i%3==0){
if($i!=0){
echo "</div>\n";
}
echo "<div class=\"row\">";
}
echo "<div>$v</div>";
}
echo "</div>";
To clarify what NOT to do...
Sinan Ulker's answer will lead to an unwanted result depending on the size of your result array.
Here is a generalized example to expose the issue:
Using this input array to represent your pdo results:
$rows=["one","two","three","four","five","six"];
Sinan's condition at the end of each iteration:
$i=1;
echo "<div class=\"row\">";
foreach($rows as $row){
echo "<div>$row</div>";
if($i%3==0)echo "</div>\n<div class='row'>"; // 6%3==0 and that's not good here
// 6%3==0 and will echo the close/open line after the content to create an empty, unwanted dom element
$i++;
}
echo "</div>\n\n";
Will create this:
<div class="row"><div>one</div><div>two</div><div>three</div></div>
<div class='row'><div>four</div><div>five</div><div>six</div></div>
<div class='row'></div> //<--- this extra element is not good
You need to add a new closure tag and open new one every 3th iteration.
<div class="row">
<?php
$sql = "SELECT * FROM products";
$stmt = $conn->query($sql);
$stmt->execute();
$i=1;
while ($row = $stmt->fetch(PDO::FETCH_OBJ)) {
?>
<div class="col-md-4">
<div class="product">
<div class="title"><?php echo $row->pname ?></div>
<div class="img"><img
src="../product/img/<?php echo $row->pnumber ?>/<?php echo $row->pthumbnail ?>.jpg?$pop210x210$"/>
</div>
<div class="vijftien"></div>
<div class="deliver">Levertijd: <strong><?php echo $row->pdelivertime ?></strong>
</div>
<div class="vijf"></div>
<div class="other"></div>
<div class="row">
<div class="col-md-6">
<div class="price"><?php echo $row->pprice ?></div>
</div>
<div class="col-md-6">
<div class="order">
<button class="log_in" id="doLogin">Meer informatie</button>
</div>
</div>
</div>
</div>
</div>
<?php
if($i%3==0)echo "</div><div class='row'>";
$i++;
} ?>
$x = 0;
echo "";
foreach($rows as $row)
{
/* added one more condition for removing empty div.... */
if ($x != 0 && $x % 3 == 0 && $x < count($rows))
{
echo "</div>\n<div class='row'>";
}
echo "<div>$row</div>";
++$x;
}
echo "";

Scaffolding for bootstrap grid with PHP loop & mysqli

thanks for taking a look at my question.
I'm trying to get PHP to output bootstrap rows that only contain 2 col-md-6 columns, instead of outputting 1 row with 1 col for each iteration.
Searching here on Stackoverflow I found a solution that makes sense but when I implement it, the HTML that I get makes no sense!
I should be getting this:
<div class="row">
<div class="col-md-6"></div>
<div class="col-md-6"></div>
</div>
<div class="row">
<div class="col-md-6"></div>
<div class="col-md-6"></div>
</div>
...But I'm getting this:
<div class="col-md-6">
<div class="row">
<div class="col-md-6"></div>
<div class="col-md-6"></div>
</div>
<div class="row">
<div class="col-md-6"></div>
<div class="col-md-6"></div>
</div>
</div>
CODE:
<?php
require_once('somedb.php');
$query = mysqli_query($conn, "SELECT * FROM notyourbusiness");
$rowCount = mysqli_num_rows($query);
$i = 0;
echo '<div class="row">';
if($rowCount > 0){
while($row = mysqli_fetch_assoc($query)){
?>
<?php echo '<div class="col-md-6">'; ?>
<img src="img/project/<?php echo $row['thumb'] ?>" class="work-thumbnail" width="100">
<h2><?php echo $row["name"]; ?></h2>
<?php echo '</div>'; ?>
<?php
$i++;
if ($i%2 == 0) echo '</div><div class="row">';
} ?>
<?php } ?>
</div>
Any help will be greatly appreciated, thanks!
Can you provide us more information? It seems that the first is comming from outside of this php code.
You can try this
<?php
$query = mysqli_query($conn, "SELECT * FROM notyourbusiness");
$rowCount = mysqli_num_rows($query);
$i = 0;
if($rowCount > 0){
while($row = mysqli_fetch_assoc($query)){
$row_draw = ($i % 2 == 0) ? true : false;
# Start row div
if ($row_draw)
{
print "<div class='row'>";
}
# Print Column
print "<div class='col-md-6'>";
?>
<img src="img/project/<?php echo $row['thumb'] ?>" class="work-thumbnail" width="100">
<a href="javascript:void(0);">
<h2><?php echo $row["name"]; ?></h2>
</a>
<?php
print "</div>";
# End row div
if ($row_draw)
{
print "</div>";
}
$i++;
}
}
?>

Bootstrap how to foreach with columns inside

I have a foreach and I want to place 4 columns then break in a new row and start again but for some reason i got the column number 5(test2) bad pushed like this picture:
should be like this:
here is the code to generate that:
<div class="container">
<div class="row">
<div class="col-md-8 col-md-offset-2">
<div class="panel panel-default">
<div class="panel-heading">
Secciones
</div>
<div class="panel-body">
<div class="row">
#foreach ($boards as $board)
<div class="col-md-3">
<h3>{{$board->boaName}}</h3>
#foreach ($subboards as $subboard)
#if($subboard->boaId == $board->id)
<ul>
<li>{{$subboard->subboaName}}</li>
</ul>
#endif
#endforeach
</div>
#endforeach
</div>
</div>
</div>
</div>
</div>
</div><!--End container-->
Try moving the foreach loop outside of the <div class="row">? If that doesn't work do you think you could mock this up in a jsFiddle example?
You need a test after 4 iterations to close and open again the row div.
If you know how many columns to expect, you could do the following (I've ommited your inner content of each column for my example - I've also left the counter in so you can see the incrementation for testing):
$i = 1;
foreach($boards as $board) {
if($i == 1 || $i == 5 || $i == 9) {
echo "<div class='row'>";
echo "<div class='col-md-3'>" . $i++ . "</div>";
}
elseif($i%4 == 0) {
echo "<div class='col-md-3'>" . $i++ . "</div>";
echo "</div>";
} else {
echo "<div class='col-md-3'>" . $i++ . "</div>";
}
}
What's happening here is if the column count is the 4th iteration, it should echo out an opening <div class="row"> as well as a column. If the current column is divisible by 4, it should echo out a column with an extra closing </div> (to close the row class.)
If the current count is neither of the above, it simply echo's out a column.
You can, of course, mod the above if the amount of potential columns is unknown.

PHP Iterate 12 items perform echo on every third

Hi I have been chasing my tail for a while on this one and wondered if someone could solve my headache.
Basically I am rendering 12 items to the page. Each 3 items need to be wrapped in a row like:
<div class='row'>
<div class='item'>
</div>
<div class='item'>
</div>
<div class='item'>
</div>
</div>
<div class='row'>
<div class='item'>
</div>
<div class='item'>
</div>
<div class='item'>
</div>
</div>
<div class='row'>
<div class='item'>
</div>
<div class='item'>
</div>
<div class='item'>
</div>
</div>
<div class='row'>
<div class='item'>
</div>
<div class='item'>
</div>
<div class='item'>
</div>
</div>
Thanks in advance.
Hi I think some code would help:
$i=0;
foreach($posts as $p) {
$i++
}
So basically within the for each I will be outputting a row and 3 items.The results are coming from a database query. I have tried a few different approaches such as
if($i == 1) {echo "<div class='row'>";}
if ($counter % 4 == 0) {
echo "</div><div class='row'>";
}
However I keep failing, please note these are just snippets of code.
You need to use two loops:
// Outer loop for each row
for ($row = 0; $row < 4; $row++) {
echo '<row>';
// Inner loop for the items
for ($item = 0; $item < 3; $item++) {
echo '<item>';
}
echo '</row>';
}
You should have done it yourself. it needs to know very basic of loop.
try like this:
for($i=0;$i <= 3; $i++){ //outer loop for 12 times
echo "<row>"; // start row
for ($j=0;$j<3;$j++){ // inner loops for echoing 3 times
echo "<item>"; //echo item
}
echo "</row>"; // end row
}

I have used "\n" for new line in demo. if you needed new line then you can use <br />

How do I group a div in some class on MySQL while

I want add a different class on my MySQL result.
<?php while ($fetch = $db->fetch($query)) { ?>
<div class="result"><?php echo $fetch['title']; ?></div>
<?php } ?>
Output should be like this
<div class="group">
<div class="result">Title</div>
<div class="result">Title</div>
<div class="result">Title</div>
<div class="result">Title</div>
<div class="result">Title</div>
<div class="result">Title</div>
</div>
<div class="group">
<div class="result">Title</div>
<div class="result">Title</div>
<div class="result">Title</div>
<div class="result">Title</div>
<div class="result">Title</div>
<div class="result">Title</div>
</div>
<div class="group">
<div class="result">Title</div>
<div class="result">Title</div>
<div class="result">Title</div>
</div>
Here, every 6 results will have <div class="group"></div>.
Let me know
<div class="group">
<?php
$count = 0;
while ($fetch = $db->fetch($query)) {
if (++$count == 6) {
echo '</div><div class="group">';
$count = 0;
}
echo '<div class="result">' . $fetch['title'] . '</div>';
}
?>
</div>
create a counter that increments every time the loop is ran, then at the beginning of each loop check the value. if the value == 6 then close the current div and open a new one with the class change (you could make 2 counters to flip flop back and forth). Reset your counter after the div change.
--edit added code--
Make yourself 2 'group' div classes, 'group1' and 'group0' for the flip-flop
<div class="group1">
<?php
$count = 0;
$divstyle = 1;
while ($fetch = $db->fetch($query)) {
if (++$count == 6) {
echo '</div><div class="group'.(++$divstyle % 2).'">';
$count = 0;
}
echo '<div class="result">' . $fetch['title'] . '</div>';
}
?>
</div>
This might be a bit bad...
<?php $cnt=0;while ($fetch = $db->fetch($query)) { ?>
<div class="result"><?php if($cnt%6==0){echo "<div class=\"group\">";} echo $fetch['title'];if($cnt%6==0){echo "</div>";} $cnt++;?></div>
<?php } ?>
