I have two arrays myarray1 has name of images and myarray2 has the address of images,
I am going to show image names and their addresses in pagination but do not know how to complete the code.
$pages = array_chunk($myarray1,10);
$addrs = array_chunk($myarray2,10);
$page_number = 1
$count = 0;
echo'<table>';
echo'<tr>';
foreach ($pages[$page_number] as $i) {
$counter++;
if ($count == 5) {
echo '</tr><tr>';
$counter = 0;
}
echo'<td>'.$i. " AND " . <<Value of addrs array goes here
echo'</td>';
}
.......
I'll do it on this way
$count = 1;
foreach ($pages[$page_number] as $key => $i) {
if ($count % 5 == 0) {
echo '</tr><tr>';
echo '</div>';
echo '</div>';
}
echo'<td>'.$i. " AND " . $addrs[$page_number][$key]
echo'</td>';
$count++; // increase at the end.
}
if you can try to var_dump those arrays before foreach just to be clear how structure looks like.
Try something like this: (note also the counter++ is changed in $count++)
foreach ($pages[$page_number] as $key => $i) {
$count++;
if ($count == 5) {
echo '</tr><tr>';
echo '</div>';
echo '</div>';
$count = 0;
}
echo'<td>'.$i. " AND " . $addrs[$page_number][$key]
echo'</td>';
}

I have a repeater from ACF and what I want to is loop and count the items and based on the counted items output a particular css class.
Can I get help so the output of css classes depends on the counted items. For example if there was six items the class would be col-6 etc...
<?php
if( have_rows('rainbow') ):
$counter = 0;
while( have_rows('rainbow') ): the_row();
// vars
$name = get_sub_field('name');
$age = get_sub_field('age');
$cssClass = 'col';
for($i = 0; $i < $counter; $i++) {
if($counter === 6) {
$cssClass = 'col-lg-4';
} elseif ($counter == 4) {
$cssClass = 'col-xl-6';
}
else {
$cssClass = 'col';
}
}
echo '<div class=\'' . $cssClass. '\'>';
echo "<h4>" . $name . "</h4>";
echo "<p>" . $age . "</p>";
echo $counter;
echo '</div>';
$counter++;
endwhile;
endif;
?>
Don't know why are you using for loop here, $i < $counter this condition cant be true because $i and $counter both of them started from 0. so 0 < 0 == FALSE
You just need to remove for loop inside your while loop.
Or, if you are using for loop somewhere else in your code, then you can just move your conditions outside the for loop.
Second Solution:
Second, if you start $counter from 1 then you can achieve your desired result as given example:
<?php
$array = array(1,2,3,4,5,6);
$counter = 1;
foreach ($array as $key => $value) {
$cssClass = 'col';
for($i = 0; $i < $counter; $i++) {
if($counter === 6) {
$cssClass = 'col-lg-4';
} elseif ($counter == 4) {
$cssClass = 'col-xl-6';
}
else {
$cssClass = 'col';
}
}
echo $cssClass."<br/>";
$counter++;
}
?>
Result:
col
col
col
col-xl-6
col
col-lg-4
<?php
$counter = 1;
while( have_rows('rainbow') ): the_row();
// vars
$name = get_sub_field('name');
$age = get_sub_field('age');
if ( $counter == 4 ) {
$cssClass = 'col-xl-6';
} elseif ( $counter == 6 ) {
$cssClass = 'col-lg-4';
} else {
$cssClass = 'col';
}
echo '<div class="' . $cssClass . '">';
echo "<h4>" . $name . "</h4>";
echo "<p>" . $age . "</p>";
echo $counter;
echo '</div>';
$counter++;
endwhile;

I cannot solve problem with starting ending divs after couple of elements from array.
What i want to get is something like that:
<div>
element1
element2
element3
element4
</div>
<div>
element5
element6
element7
element8
</div>
<div>
element9
element10
</div>
Here is my php code:
$array = array("element1","element2","element3","element4","element5","element6","element7","element8","element9","element10");
$perRow = 4;
$count = 1;
foreach ($array as $arr){
// here div needs to start, use 4 elements from array and close
if($count % $perRow == 0 OR $count == 1){
echo '<div>';
}
echo $arr . '<br>';
// here should div close
$count++;
}
Try something like this
$array = array("element1","element2","element3","element4","element5","element6","element7","element8","element9","element10");
$perRow = 4;
$count = 0;
echo '<div>';
foreach ($array as $arr){
// here div needs to start, use 4 elements from array and close
if($count % $perRow == 0 && $count!=0){
echo '</div><div>';
}
echo $arr . '<br>';
// here should div close
$count++;
}
echo '</div>';
Okay I am not familiar with arrays and maybe something like this would work:
$array = array("element1","element2","element3","element4","element5","element6","element7","element8","element9","element10");
$i=0;
echo '<div>'
if (i<3) {
echo '$array[$i]';
$i++;
}
echo '</div>';
echo '<div>';
if ($i>3 && $i<7) {
echo '$array[$i]';
$i++;
}
echo '</div>';
echo '<div>';
if ($i>7 && $i<10) {
echo '$array[$i]';
$i++;
}
echo '</div>';
I want to mysql_fetch_array 100 items from mysql database. then every 25 items wrap a div.
also, I make a total items result check.
My code as below, but it will add <div> to every item, no as my require. So how to make it easier? Thanks.
if (mysql_num_rows($result) != 0) {
$total = mysql_num_rows($result);
$num = 1;
while ($row = mysql_fetch_array($result)) {
if ($num === 1) {
echo '<div>';
}
echo $row['title'] . '<br />';
if ($total < 26) {
echo '</div>';
}
else {
if ($num === 26) {
echo '<div>';
}
if ($total < 51) {
echo '</div>';
}
else {
if ($num === 51) {
echo '<div>';
}
if ($total < 76) {
echo '</div>';
}
else {
if ($num === 75) {
echo '<div>';
}
if ($total < 101) {
echo '</div>';
}
}
}
}
$num++;
}
}
You can use the mod operator.
See: http://php.net/manual/en/internals2.opcodes.mod.php
echo '<div>';
while($row = mysql_fetch_array($result)){
....
if (($num % 25) === 1) { echo '</div><div>' }
$num++;
}
echo '</div>';
Try This...
if(mysql_num_rows($result)!=0){
$total = mysql_num_rows($result);
$num=1;
while($row = mysql_fetch_array($result)){
if($num===1)
echo '<div>';
echo $row['title'].'<br />';
if($num==25){
echo '</div>';
$num=1;
}
$num++;
}
}
use the mod operator.
$num =1;
while($row = mysql_fetch_array($result)){
if (($num % 25) === 1) { echo '<div>' }
-------here data ----
if (($num % 25) === 0) { echo '</div>' }
$num++;
}
My advice is to separate your concerns... Give it a shot more like this:
// first get all your data.
$results = array();
while($row = mysql_fetch_array($result)){
$results[] = $row;
}
// now you have an array of all of your records.
if (!empty($results)) {
// total count of the array up front.
$total = count($results);
$interval = 0;
// save the data in a buffer for echoing later.
$buffer = array('<div>');
foreach($results as $row) {
$buffer[] = $row['title'] . '<br />';
if (++$interval === 24) { // notice the prefix ++
$interval = 0;
// close and re-open divs
$buffer[] = '</div><div>';
}
}
// one final close tag
$buffer[] = '</div>';
// now we zip it up and echo the content.
echo implode('', $buffer);
}
Here is how I do it...
$count = 0;
while($row = mysql_fetch_array($result)){
if ($count%$25 == 0)
{
echo "<div>";
}
//whatever your data goes here
count++
if ($count%$25 == 0)
{
echo "</div>";
}
}
I have this script that displays a max of 5 images for each row, but for some reason my <ul> tag won't close correctly if the number of items isn't an exact multiple of 5. How can I correct this problem so the <ul> tag will close even if the number of listed images is less then 5?
Here is my PHP code.
if (!$dbc) {
print mysqli_error($mysqli);
} else {
$row_count = 0;
while($row = mysqli_fetch_array($dbc)){
if($row_count % 5 == 0){
echo "<ul>";
}
echo "<li><a href='" .$row["url"]. "' title='".$row['title']."'>";
echo "<img src='".$row['src']."'></a></li>";
if($row_count % 5 == 4) {
echo "</ul>";
}
$row_count++;
}
}
below the loop, check if
if (!$dbc) {
print mysqli_error($mysqli);
} else {
$row_count = 0;
while($row = mysqli_fetch_array($dbc)){
if($row_count % 5 == 0){
echo "<ul>";
}
echo "<li><a href='" .$row["url"]. "' title='".$row['title']."'>";
echo "<img src='".$row['src']."'></a></li>";
if($row_count % 5 == 4) {
echo "</ul>";
}
$row_count++;
}
if ( (($row_count % 5) > 0) && (($row_count % 5) < 4))
echo "</ul>";
}
$multiple = false;
if (!$dbc) {
print mysqli_error($mysqli);
} else {
$row_count = 0;
while($row = mysqli_fetch_array($dbc)){
if($row_count % 5 == 0){
echo "<ul>";
}
echo "<li><a href='" .$row["url"]. "' title='".$row['title']."'>";
echo "<img src='".$row['src']."'></a></li>";
if($row_count % 5 == 4) {
$multiple = true;
echo "</ul>";
} else {
$multiple = false;
}
$row_count++;
}
if($multiple == false) {
echo "</ul>";
}
}
if (!$dbc) {
print mysqli_error($mysqli);} else {
$row_count = 0;
//tank start
$total_rows = mysqli_num_rows($dbc);
//tank end
while($row = mysqli_fetch_array($dbc)){
if($row_count % 5 == 0){
echo "<ul>";
}
echo "<li><a href='" .$row["url"]. "' title='".$row['title']."'>";
echo "<img src='".$row['src']."'></a></li>";
//tank start
if($row_count % 5 == 4 || $row_count==$total_rows) {
//tank end
echo "</ul>";
}
$row_count++;
}
Here's my updated solution. I think it looks a little clearer. I do setup a few variables to get rid of some IF statements, and replace them with FOR loops. Mainly for readability and it's the way i thought of doing it.
$itemsperrow = 5;
$items = mysqli_num_rows($dbc);
$rows = $items / $itemsperrow;
$itemcount = 0;
if (!$dbc)
{
echo(mysqli_error($mysqli));
}
else
{
for ($int = 0; $int < $rows; $int++)
{
echo "<ul>";
for ($item = 0; $item < $itemsperrow; $item++)
{
if ($itemcount >= $items)
{
echo "</ul>";
exit;
}
else
{
$row = mysqli_fetch_array($dbc);
echo "<li><a href='". $row["url"] . "'>";
echo "<img src='" . $row["src"] . "' title='" . $row["title"] . "'/></a></li>";
$itemcount++;
}
}
echo "</ul>";
}
}
I have
foreach ($a as $key => $value) {
echo "<DIV id='container'>
<DIV id='middle'>$value</DIV>
</DIV>";
//echo "<br />$key:$value<br />\n";
}
which displays result one below other,
like
1234
5678
2010-05-20
5678
1590
2010-05-19
but i want it in a table like structure like
1234 5678 2010-05-20
5678 1590 2010-05-19
how can i do that?
You could keep track with for example modulus if you should begin a new row or not.
EDITED after reformatting of the question
I think what you need is simply something on the line of:
echo '<table><tr>';
$n = 0;
foreach ($a as $key => $value)
{
if ($n==3)
{
$n = 0;
echo '</tr><tr>';
}
echo '<td>'.$value.'</td>';
$n++;
}
echo '</tr></table>';
You can do like:
$counter = 0;
foreach ($a as $key => $value) {
$counter++;
if (($counter % 3) === 0)
{
echo "<DIV id='container'>
<DIV id='middle'>$value</DIV>
</DIV>";
}
else
{
echo "<DIV id='container' style='float:left;'>
<DIV id='middle'>$value</DIV>
</DIV>";
}
}
Kind of what nico was saying:
foreach ($a as $key => $value)
{
echo '<div style="width:33%;float:left">'.$value.'</div>';
}
Or what don was saying:
$i = 0;
$open = false;
echo '<table>';
foreach( $a as $key => $value )
{
if( 0 == $i % 3 ) {
echo '<tr>';
$open = true;
}
echo "<td>$value</td>";
if( 2 == $i % 3 ) {
echo '</tr>';
$open = false;
}
$i++;
}
if( $open )
echo '</tr>';
echo '</table>';
Simply use like this,
foreach ($a as $key => $value) {
echo "<DIV id='container' style='display:inline'>
<DIV id='middle' style='display:inline'>$value</DIV>
</DIV>";
//echo "<br />$key:$value<br />\n";
}
add the break statement depending on your second line.
By default, div's don't float next to each other. You could give all the div's, except every third one float: left in the style. However it's okay to use table's if your displaying a table.
If you can derive from the value of $key wether to start a new row or not you can do something like:
echo '<table><tr>';
foreach ($a as $key => $value) {
if($key == 'somevalue'){
//start a new row if the $key allow
echo '</tr><tr>';
}
echo '<td>'.$value.'</td>';
}
echo '</tr></table>';
If you can't derive from the value of $key wether to start a new row or not, use a counter, like so:
echo '<table><tr>';
$cnt = 0;
foreach ($a as $key => $value) {
if($cnt % 3 == 0){
//start a new row if this row contians 3 cells
echo '</tr><tr>';
}
echo '<td>'.$value.'</td>';
$cnt++;
}
echo '</tr></table>';
