i want to add active class in while loop first div.
but its not working
$ban_sql = mysql_query("SELECT * FROM banners");
while ($row = mysql_fetch_assoc($ban_sql)){
echo '<div class="item ';
if($row <= 1) {
echo 'active ">';
}
else
{
echo '">';
}
echo '<img src="'.$row['banner_img'].'"/> </div>';
}
This should do the trick:
$ban_sql = mysql_query("SELECT * FROM banners");
$count = 0;
while ($row = mysql_fetch_assoc($ban_sql)){
echo '<div class="item ';
if($count == 0) {
echo 'active ">';
}
else
{
echo '">';
}
echo '<img src="'.$row['banner_img'].'"/> </div>';
$count++;
}
$row will contain a MySQL rowset so you need a separate variable to store the current row iteration count.

I have a foreach statement in my app that echos a list of my database results:
<?php
foreach($featured_projects as $fp) {
echo '<div class="result">';
echo $fp['project_name'];
echo '</div>';
}
?>
I would like to:
On every third result, give the div a different class. How can I achieve this?
You can use a counter and the modulo/modulus operator as per below:
<?php
// control variable
$counter = 0;
foreach($featured_projects as $fp) {
// reset the variable
$class = '';
// on every third result, set the variable value
if(++$counter % 3 === 0) {
$class = ' third';
}
// your code with the variable that holds the desirable CSS class name
echo '<div class="result' . $class . '">';
echo $fp['project_name'];
echo '</div>';
}
?>
<?php
foreach ($featured_projects as $i => $fp) {
echo '<div class="result' . ($i % 3 === 0 ? ' third' : '') . '">';
echo $fp['project_name'];
echo '</div>';
}
?>
If the $featured_projects array is based on incremental index you could simply use the index and the modulo % operator.
Otherwise you would have to add a counter.
http://php.net/manual/en/language.operators.arithmetic.php
add a counter in this loop and check if counter equals three and apply class.
Using a counter and modulo operator this is easy to implement
<?php
foreach($featured_projects as $fp) {
if(++$i % 3 === 0) {
$class = ' something';
} else {
$class = '';
}
echo '<div class="result' . $class . '">';
echo $fp['project_name'];
echo '</div>';
}
?>
<?php
$i = 0;
foreach($featured_projects as $fp) {
echo '<div class="'.($i++%3 ? 'result' : 'other_class').'">';
echo $fp['project_name'];
echo '</div>';
}
?>
What leaves your code mostly in tact would be
<?php
$i = 1;
foreach($featured_projects as $fp) {
printf ('<div class="%s">',(($i % 3) ? "result" : "result_every_third" ));
echo $fp['project_name'];
echo '</div>';
$i++;
}
?>
But you may want to consider using a for or while construct around "each($featured_projects)" (see http://php.net/manual/en/function.each.php) which may result in neater code.
<?php
$counter = 0;
foreach ($featured_projects as $fp) {
echo '<div class="result' . ($counter++ % 3 === 0 ? ' third' : '') . '">';
echo $fp['project_name'];
echo '</div>';
}
?>
You can add a counter in loop ...try the following...
<?php
$i = 0;
foreach($featured_projects as $fp) {
$i = ++$i;
if(($i%3) == 0)
{
$class1 = 'test1';
}
else
{
$class1 = 'test2';
}
echo '<div class="'.$class1.'">';
echo $fp['project_name'];
echo '</div>';
}
?>
This is the working version, sorry for my prev version:
<?php
$featured_projects[0]['project_name'] = "pippo";
$featured_projects[1]['project_name'] = "pippo2";
$featured_projects[2]['project_name'] = "pippo3";
$class[0] = "class1";
$class[1] = "class2";
$i=0;
foreach($featured_projects as $fp) {
$i++;
if ($i == 3) {
$c = $class[1];
$i=0;
} else {
$c = $class[0];
}
echo "<div class=\"$c\">";
echo $fp['project_name'];
echo "</div>\n";
}
?>
Produces:
<div class="class1">pippo</div>
<div class="class1">pippo2</div>
<div class="class2">pippo3</div>
if (isset($_GET['q'])){
$q = $_GET['q'];
//variables
$sql = "SELECT * FROM products WHERE product LIKE '%$q%' OR search LIKE '%$q%'";
$result = $conn->query($sql);
//check database
if($result->num_rows > 0){
while ($row = $result->fetch_array()){
$product = $row['product'];
$productImage = $row['product_image'];
$price = $row['price'];
$seller = $row['seller_name'];
$sellerImage = $row['seller_image'];
$desc = $row['description'];
$search = $row['search'];
$console = $row['console'];
$array = array($product, $price, $productImage);
$arrayDesc = array($desc, $sellerImage);
if (preg_match('/Game/', $seller)){
for ($num = 0; $num < 3; $num++) {
echo '<div class="tile col-md-4 col-sm-3">';
if($num == 0){
echo '<div class="tileTitleBox"><h4>' . $array[$num] . '</h4></div>';
}
if($num = 1){
echo '<p class="price">' . $array[$num] . '</p>';
}
if($num = 2){
echo '<img class="tilePic" src="' . $array[$num] . '"/>';
}
// if($num = 3){
// echo '<div class = "desc"><p>' . $array[$num] . '</p></div>';
// }
echo '</div>';
}//For Iteration Loop - TILE
for($count = 0; $count < 2; $count++){
echo '<div class="tile-description col-md-4 col-sm-3 hidden">';
if($count == 0){
echo '<div class="desc"><p>' . $arrayDesc[$count] . '</p></div>';
}
if($count == 1){
echo '<img class="sellerImg" src="' . $arrayDesc[$count] . '"/>';
}
echo '</div>';
}//end for loop - TILE-DESCRIPTION
So as you see above, I have one for loop which creates the "tile" and the second which is supposed to create the "tile-description". The first one works well to create a single div with the class of "tile" in which my remaining contents is loaded into the div. But in the second for loop the "desc" dev and the "sellerImg" div are separated. The loop needs to go through the array various times.
Shown Bellow:
You can see that the "Tile" div contains "tileTitleBox", "price", and "tilePic". But the "tile-description" which is hidden, is separated into two divs. As opposed to holding both elements inside the same div.
#sam-dufel rightly pointed out you're overwriting the iterator
if($num = 1){
But in fact you shouldn't use any loops here:
echo '<div class="tile col-md-4 col-sm-3">';
echo '<div class="tileTitleBox"><h4>' . $array[0] . '</h4></div>';
echo '<p class="price">' . $array[1] . '</p>';
echo '<img class="tilePic" src="' . $array[2] . '"/>';
echo '</div>';
echo '<div class="tile-description col-md-4 col-sm-3 hidden">';
echo '<div class="desc"><p>' . $arrayDesc[0] . '</p></div>';
echo '<img class="sellerImg" src="' . $arrayDesc[1] . '"/>';
echo '</div>';
How to display this query result in 4 columns
<?php
$direction = $_POST['direction'];
$sumword = $_POST['sumword'];
$length = $_POST['length'];
$con = mysql_connect("localhost","elsha","12q(5PSZ.");
$db = mysql_select_db("elsha",$con);
$query = "SELECT answer FROM words WHERE direction = '$direction' AND sumword = '$sumword' AND sumletter = '$length'";
$result = mysql_query($query);
if(mysql_error()) {
//check that no error has occurred first; take this out in production or make more graceful handling
die(mysql_error());
}
if(mysql_num_rows($result) == 0) {
echo "No Results";
} else {
while($row = mysql_fetch_array($result)) {
echo '<img src="/images/'. $row['0'].'.jpg"><br> '. $row['0'].'<br>';
}
}
?>
like this :
result1 result2 result3 result4
result5 result6 result7 result8
Try this
$i = 0;
while($row = mysql_fetch_array($result)) {
echo '<img src="/images/'. $row['0'].'.jpg"> ';
$i++;
if($i % 4 == 1 && $i!=1){
echo '<br>';
}
}
Use flag like
$flag=0;
while($row = mysql_fetch_array($result)) {
if(($flag%4)==0) {
echo '<tr>';
}
echo '<td><img src="/images/'. $row['0'].'.jpg"><br> '. $row['0'].'</td>';
if(($flag%4)==3) {
echo '</tr>';
$flag=-1;
}
$flag++;
}
replace your while with the following code. try this
$a=1;
while($row = mysql_fetch_array($result)) {
if($a%4==0) {
echo '<img src="/images/'. $row['0'].'.jpg">'. $row['0'].'<br>';
} //4th line with break
else {
echo '<img src="/images/'. $row['0'].'.jpg"> '. $row['0'].' '; // prints first 3 lines
}
$a=$a+1;
}
I think you are trying to display the image name too below the image. Try this:
$i = 1;
while($row = mysql_fetch_array($result)) {
echo '<div class="imgs">';
echo '<img src="/images/'. $row['0'].'.jpg"><br> '. $row['0'];
echo '</div>';
if ($i === 4) {
echo '<div class="clear"></div>';
$i = 1;
} else {
$i++;
}
}
and then style div's
.imgs {
float: left;
/* other styles */
}
.clear {
clear: both;
}
how can i increment my css ID using php programmatically?
foreach ($query_cat->result() as $row_cat)
{
$row_cat_id = $row_cat->id;
echo '<div class="product-wrapper">';
echo '<div id="product-header" class="product-header">';
echo $row_cat->title;
echo '</div>';
echo '</div>';
$query_prod = $this->db->get_where('products', array('category_id'=>$row_cat_id));
foreach ($query_prod->result() as $row_prod)
{
$row_prod_id = $row_prod->id;
echo '<div id="product-contents" class="product-contents">';
echo $row_prod->title.' '.$row_prod->id;
echo '</div>';
}
}
what i want to happen is to increment the id product-header and product-contents depending on the numbers of rows generated
something like this
product-header1, product-header2, product-header3....
product-contents1, product-contents2, product-contents3....
thanks!
Just initialise an incremental variable before the foreach.
$i = $j = 0;
foreach ($query_cat->result() as $row_cat) {
$i++;
$row_cat_id = $row_cat->id;
echo '<div class="product-wrapper">';
echo '<div id="product-header'.$i.'" class="product-header">';
...
foreach ($query_prod->result() as $row_prod) {
$j++;
$row_prod_id = $row_prod->id;
echo '<div id="product-contents'.$j.'" class="product-contents">';
...
}
}
$i = $j = 1;
foreach (...) {
printf('<div id="product-header-%u" class="product-header">', $i++);
foreach (...) {
printf('<div id="product-contents-%u" class="product-contents">', $j++);
}
}
Let's say I have a user that entered 12 links into the database but when they are displayed I want to break up the links into groups of 3 and repeat the groups of three until all 12 kinks are displayed for example.
<div>
<p>Link 1</p>
<p>Link 2</p>
<p>Link 3</p>
</div>
Here is part of the code I'm working with. How should my code look like?
while ($row = mysqli_fetch_assoc($dbc)) {
if (!empty($row['category']) && !empty($row['url'])) {
echo '<div>';
echo '<p>' . $row['category'] . '</p>';
echo '</div>';
}
}
Something like this gets you three links per div. We add the extra conditional echo at the end for the case that there's not a multiple of 3 links
$ctr = 0;
while ($row = mysqli_fetch_assoc($dbc)) {
if (!empty($row['category']) && !empty($row['url'])) {
if ($ctr%3 == 0) {
echo '<div>';
}
$ctr ++;
echo '<p>' . $row['category'] . '</p?';
if ($ctr%3 == 0) {
echo '</div>';
}
}
}
if ($ctr%3 != 0) {
echo '</div>';
}
if you want to avoid incrementing/resetting i every time you reach three, you can just use the modulus operator:
http://php.net/manual/en/language.operators.arithmetic.php
Something like:
if( $i%3 == 0 ){
// divisible by 3...
}
An easier method would be more like:
while(true) {
$c = 0;
echo "<div>";
while ($row = mysqli_fetch_assoc($dbc) && $c++ < 3) {
if (!empty($row['category']) && !empty($row['url'])) {
echo '<p>' . $row['category'] . '</p>';
}
}
echo "</div>";
if(empty($row))
break;
}
