I have a problem about PHP coding. I manage to display the first 12 image nicely on the image grid but after that, the picture seems to be out of place.
<?php
$i = 0;
while ($row = mysqli_fetch_array($result)) {
if ($i % 3 == 0) {
echo "<div class='w3-quarter'>";
}
echo "<img src='images/{$row['image']}' onclick=onClick(this) style='width:100%'>";
if ($i % 3 == 2) {
echo"</div>";
}
$i++;
}
?>
I want the output to look like this
2
and the css i using is w3-quarter from w3.css

I have 11 news then i want to display like
first column need only one news
second column need 5 news
third column need the rest of 5 news
I tried this but no luck, it shows first column and second column and the rest outside column
$rows = array(
'Title1',
'Title2',
'Title3',
'Title4',
'Title5',
'Title6',
'Title7',
'Title8',
'Title9',
'Title10',
'Title11',
);
$total_rows = count($rows);
$total_cols = $total_rows - 1;// remove first one for the first column
$left_column = ceil($total_cols / 2);
$right_column = $total_cols - $left_column;
$i = 0;
echo "<div class='row'>";
foreach ($rows as $row) {
$i++;
if ($i == 1) {
$class = "primary_post";
echo "<div class='col-md-4 main'>";
} elseif ($i <= $left_column) {
$class = "other_post";
echo "<div class='col-md-4 left'>";
} elseif ($i == $right_column) {
$class = "other_post";
echo "<div class='col-md-4 right'>";
} else {
$class = "other_post";
}
echo "<div class='card {$class}'>$i</div>";
if ($i == 1 || $i == $left_column || $i == $right_column) {
echo "</div>";
} else {
echo "";
}
}
echo "</div>";
The last echo "</div>"; supposed to be in the FOR loop not outside of it.
Also, you can split the array into chunks;
$firstColumn = array_splice($rows,0,1);
$secondColumn = array_splice($rows,0,5);
Rest are in the $rows variable.
So instead of dealing with ifs in for loops, you can use 3 different loops and list items in desired HTML objects.
<div>
<?php if ($result->num_rows > 0) {
$i=1;
while($row = $result->fetch_assoc()) {
if( $i % 6 == 0 )
{ ?>
</div>
<div>
<?php } ?>
<h4><?php echo $row["city"] ?></h4>
<h6><?php echo $row["info"] ?></h6>
<?php $i++;
}
} else {
echo "0 results";
}
?>
</div>
Goal: div's with each 6 rows in it.
When I use $i=1, the first gets 5 results and the other ones get 6.
When I use $i=0 the first one is empty and the other ones get 6.
How to get the first div also filled with 6 results?
Try using array_chunk. That way you don't have to worry where to put your div ends and it's more readable:
$rows = [];
while ($row = $result->fetch_assoc()) {
$rows[] = $row;
}
foreach (array_chunk($rows, 6) as $subset) {
echo "<div>";
foreach ($subset as $row) {
echo "<h4>{$row["city"]}</h4>"
echo "<h6>{$row["info"]}</h6>"
}
echo "</div>";
}
Using array_chunk as proposed by #Justinas is a good way to refactor code. Yet, taking your original code, the issue is about where you check printed amount. It is wrong to first check output amount as it breaks the logic for the first iteration. Please, refer to the code below.
<div>
<?php
if ($result->num_rows > 0) {
$i = 1;
while ($row = $result->fetch_assoc()) {
# if ($i % 6 == 0) {
# echo '</div><div>';
# }
# move commented code from above to ...
echo "<h4>{$row["city"]}</h4>";
echo "<h6>{$row["info"]}</h6>";
# ... here
if ($i % 6 == 0) {
echo '</div><div>';
}
$i++;
}
} else {
echo "0 results";
}
?>
</div>
You can try setting $i = 0 then excluding it in your if statement with
if ($i > 0 && $i % 6 == 0)
since 0 % 6 == 0.
Heres the scenario, I have array with 7 items and I want to separate them in every fourth iteration.. just like this
$counter2 = 0;
$counter3 = 0;
$counter4 = 0;
$sample_array = array('Aso','Pusa','Daga','Kuting','Tuta','Bubwit','Boom');
foreach($sample_array as $sample_array_value)
{
if(++$counter4 % 4 == 0)
{
echo $sample_array_value;
echo "</div>";
}
elseif(++$counter3 % 3 == 0)
{
echo $sample_array_value;
}
elseif(++$counter2 % 2 == 0)
{
echo $sample_array_value;
}
else
{
echo "<div>";
echo $sample_array_value;
}
}
The out put will be div AsoPusaDagaKuting /div div TutaBubwitBoom
The problem is when it ends in iteration that doesn't count 4 it doesn't give the separator ending..
I need it to output div AsoPusaDagaKuting /div div TutaBubwitBoom /div
Thanks in advance...
You can split it with array_chunk, implode the new subarrays of 4 with array_map, then echo it with implode.
$sample_array = array('Aso','Pusa','Daga','Kuting','Tuta','Bubwit','Boom');
echo "<div>", implode("</div><div>", array_map("implode", array_chunk($sample_array, 4))), "</div>";
Result:
<div>AsoPusaDagaKuting</div><div>TutaBubwitBoom</div>
Try this:
$i = 0;
foreach($sample_array as $sample_array_value)
{
if(++$counter4 % 4 == 0)
{
echo $sample_array_value;
echo "</div>";
}
elseif(++$counter3 % 3 == 0 || ++$counter2 % 2 == 0)
{
echo $sample_array_value;
}
else
{
echo "<div>";
echo $sample_array_value;
}
$i++;
}
if ($i % 4 != 0) {
echo "</div>";
}
You are printing the values inside every condition, then why not use echo once outside any condition? Also you want to close and open a div tag for the forth element, then only 1 counter would do the trick. Only this will work -
$sample_array = array('Aso','Pusa','Daga','Kuting','Tuta','Bubwit','Boom');
$i = 0;
echo "<div>";
foreach($sample_array as $sample_array_value)
{
if($i > 0 && $i % 4 == 0)
{
echo "</div><div>";
}
echo $sample_array_value;
$i++;
}
echo "</div>";
Output
<div>AsoPusaDagaKuting</div><div>TutaBubwitBoom</div>
I am having the worst time trying to create this, it should be simple. I have an $info array that consists of $person=>$personInfoArray and I am trying to say, for the first six, do one column, for the next x amount, do another column.
What I have is:
$infoCounter = 0;
foreach($info as $person => $information){
$infoCounter++;
echo '<tr>';
if($infoCounter <= 5){
echo '<td>'.$person.'</td>';
echo '<td>'.$information['Extension'].'</td>';
}elseif($infoCounter > 5){
echo '<td>'.$person.'</td>';
echo '<td>'.$information['Extension'].'</td>';
}
echo '</tr>';
}
I am essentially trying to create a table that looks like:
Name Extension Name Extension
--------------------------------------------------------------------
Some one 54545 Name 9785
Some One else 54212 Something else 44121
But I am getting:
Name Extension Name Extension
--------------------------------------------------------------------
Some one 54545
Name 9785
Some One else 54212
Something else 44121
Thoughts? This should be ridiculously easy.
See that you are creating a <tr> for each person, try doing something like this:
$infoCounter = 0;
foreach($info as $person => $information){
if ($infoCounter % 2 == 0) {
echo '<tr>';
}
echo '<td>'.$person.'</td>';
echo '<td>'.$information['Extension'].'</td>';
if ($infoCounter % 2 == 0) {
echo '</tr>';
}
$infoCounter++;
}
Check that % its the modulus
You will always have "2" columns with this code. I think what you are after is this.
$counter = 0;
foreach($info as $person => $information){
if($counter == 0) echo "<tr>";
echo "<td>$person</td>";
echo "<td>$information</td>";
$counter += 2;
if($counter == 4) {
$counter = 0;
echo "</tr>";
}
}
Keep in mind this is crude and off the top of my head. Not sure why you want 4 columns for 2 column information, other than formatting.
I am trying to limit the printing of table cells to 3 per row. This worked in one example, but clearly not working when I tried to use the same code somewhere else in the site. This is the code:
$n=3;
echo "<table cellpadding='10' cellspacing='10' style='margin-right:-70px;'><tr>";
$users_count = count($users);
for($i=0; $i<$users_count;$i++)
{
$temp = array();
$temp = $users[$i];
echo "<td>";
echo "<div id='kitchen_box'>";
echo "<div id='kitchen_box_details'>";
echo "<h4>".$temp->fullname . "</h4><br>";
if(strcmp($temp->address, '') == 0)
echo $temp->city;
else
echo $temp->address.", ".$temp->city;
echo "</div>";
echo "<div id='kitchen_box_pic'><img id='kitchen_image' src='".$temp->profilepic."' /></div>";
echo "</div>";
echo "</td>";
if($i != 0){
if($i % $n == 0 && $i != $users_count-1){
echo "</tr><tr>";
}
else{
echo ""; //if it is the last in the loop - do not echo
}
}
}
echo "</table>";
I can't see why this wouldn't work! I would really appreciate support on the matter :)
There are several issues with your code. But your main issue is that you're using a zero-based increment, but doing a 1-based check. So, a table of your the results of an $i!=0 && $i%$n==0 goes like this:
$i $result
0 false
1 false
2 false
3 true
So, you see, the result closes the row after the fourth, not the third cell. To fix this, change the line to:
if($i % $n == $n-1 && $i != $users_count-1){
You should also include a closing </tr> tag with your closing </table> tag.
Incidentally, you shouldn't give the same ID to multiple elements on a page. Each of your kitchen_box and kitchen_box_div DIV tags will have the same ID. If you want this for CSS, use classes. Otherwise, you might try adding the value of $i to each ID.
Nitpicking on request:
The line $temp = array(); seems a little pointless, especially since you don't want $temp to be an array, but an object.
The else{ echo ""; } lines are also redundant.
You don't need the if($i != 0) check now because that case will not pass the next test anymore.
Otherwise the code seems fine to me.
I think the problem is that your $i starts at zero.
Let's look at your conditions before creating a new row :
if($i != 0){
if($i % $n == 0 && $i != $users_count-1)
If $i = 0, the first condition isn't matched. Then the second isn't for $i = 1 and $i = 2. And then your script creates another ... in your first row before matching your if conditions for the first time.
I guess you could move this part of the code right after the beginning of the for instructions :
for($i=0; $i<$users_count;$i++)
{
if($i != 0)
{
if($i % $n == 0 && $i != $users_count-1){
echo "</tr><tr>";
}
else{
echo ""; //if it is the last in the loop - do not echo
}
}
// Echo your <td> ... </td>
}
echo "</tr></table>";
