I have encountered a small issue, and I'm not sure what's the best way to solve this.
Using this code below I'm getting 5 items per <div> in 1st loop, but starting from the 2nd - 4 items per <div>.
<?php $count = 1;
while($data = mysqli_fetch_array($result)) {
if($count === 1) {
echo "<div id='".$data['title']."' class='images-container'>";
}
echo "<div id='img_div'>";
echo "<img src='uploads/" . $data['filename']."'>";
echo "<p class='img_title' id='".$data['title']."'>" .$data['title']. "</p>";
echo "<p id='img_desc'>" .$data['photo_description']. "</p>";
echo "<p>" .$data['price']. "</p>";
echo "</div>";
if($count % 5 === 0) {
echo "</div>";
$count = 1;
echo "<div class='images-container'>";
}
$count++;
}
?>
If I wouldn't need an id for "<div id='".$data['title']."' class='images-container'>"; I would know how to solve this, but since I need to have a specificid, I'm not really sure how.

I'm working on mansory gallery here images fetching into the row first row contains three images and then for the second row contains two images and so on.
Now currently all images coming inside same row. I want to add in a loop I had tried but unable to achieve the result. For inspiration link
<?php
include('admin/config.php');
$result = mysqli_query($db, "SELECT * FROM gallery order by id desc");
// var_dump($result->num_rows);
while ($row = mysqli_fetch_array($result)) {
echo "<div class='gallery-items'>";
echo "<div class='mansory-item'>";
echo "<a href='admin/images/".$row['path']."' data-lightbox='gallery' class='ansa-thumb'>";
echo "<img src='admin/images/".$row['path']."' class='item-img img-1'>";
echo "</a>";
echo "</div>";
echo "</div>";
}
?>
Current output
Expected output
Can anyone suggest me how should i get this output.
Check below snippet,
$inc = 4;
$i = 1;
while ($row = mysqli_fetch_array($result)) {
if (empty($temp) || $inc != $temp) {
$temp = $inc;
if ($inc == 4) {
echo "<div class='gallery-grid'>";
}
echo "<div class='gallery-items'>";
}
if ($i <= $inc) {
// echo $i . '<>';
echo "<div class='mansory-item'>";
echo "<a href='admin/images/" . $row['username'] . "' data-lightbox='gallery' class='ansa-thumb'>";
echo "<img src='admin/images/" . $row['username'] . "' class='item-img img-1'>";
echo "</a>";
echo "</div>";
$i++;
}
if ($i == $inc) {
echo "</div>";
if ($i == 3) {
echo "</div>";
}
$i = 1;
$inc = ($inc == 4 ? 3 : 4);
}
}
I am stuck in a weird problem, I want to show the continuous number till the last in the row and cols,
instead of that its showing form 1-50 and then again the row starts with 1 up-to 50.
<?php
$rows = 10;
$cols = 50;
$x=1 ;
echo "<table border='1'>";
for($tr=1;$tr<=$rows;$tr++){
echo "<tr>";
for($td=1;$td<=$cols;$td++){
echo "<td>$td</td>";
}
echo "</tr>";
}
echo "</table>";
?>
Thanks
$rows = 10;
$cols = 50;
$x=1 ;
echo "<table border='1'>";
for($tr=1;$tr<=$rows;$tr++){
$style = "green";
if ($tr % 2 == 0) {
$style = "#ccc";
}
echo "<tr style='background-color:".$style."'>";
for($td=1;$td<=$cols;$td++)
{
echo "<td>$x</td>";
$x++;
}
echo "</tr>";
}
echo "</table>";
You are outputting $td which resets at every new tablerow.
Instead, you would like to output an incrementing $x, if I'm not mistaken.
<?php
$rows = 10;
$cols = 50;
$x=1 ;
echo "<table border='1'>";
for($tr=1;$tr<=$rows;$tr++){
echo "<tr>";
for($td=1;$td<=$cols;$td++){
echo "<td>" . $x . "</td>";
$x++;
}
echo "</tr>";
}
echo "</table>";
?>
In response to your comment on another answer: if you would want alternating row colors, you could use $tr and check wether it is even or uneven:
if($tr % 2 == 0)
{
// use color1
}
else
{
// use color2
}
<?php
$result10=mysql_query("SELECT * FROM blog_articles WHERE fk_semikatagori_id = 9") or die(mysql_error());
?>
<?php
$index = 1;
while($row10 = mysql_fetch_array($result10)) {
if($index%2==0) {
echo "<span class=\"f\">";
echo $row10['english_navn'];
echo "</span><br />";
}
else {
echo "<p><span class=\"f\">";
echo $row10['english_navn'];
echo "</span></p><br />";
echo "<p>";
echo $row10['english_tekst'];
echo "</p><br />";
}
$index++;
}
?>
Any ideas how I can display the number for each row?
I want it to start from 1.
I cant display the id from Mysql because it doesnt start from 1.
You could for example use a for() loop instead of a while() loop,
for ($index = 0; $row10 = mysql_fetch_array($result10); $index++)
{
...
echo $index;
}
Then the counter would be echoed.
$index = 1;
while( $row = mysql_fetch_array($result) )
{
// display the number for each row
echo $index;
// other code...
// increment number
$index++;
}
Thanks everyone for the help, it worked.
Here is the code if anyone else can use it.
<?php
$index = 1;
for ($index2 = 1; $row10 = mysql_fetch_array($result10); $index2++)
{
if($index%2==0)
{
echo "<span class=\"f\">";
echo $row10['english_navn'];
echo $index2;
echo "</span><br />";
}
else
{
echo "<p><span class=\"f\">";
echo $row10['english_navn'];
echo "</span></p><br />";
echo "<p>";
echo $index2;
echo $row10['english_tekst'];
echo "</p><br />";
}
$index++;
}
?>
I think the best solution that you can get are the follow:
Make a for statement:
<?php
for($idx=1; $row = mysql_fetch_array($result10); $idx++) {
...
}
?>
as said before or use the follow:
<?php
$idx = 1;
while($row = mysql_fetch_array($result10)) {
...
$idx++;
}
?>
I would recommend you to make a like upgrade in your select statement to get a faster result (if you start get many rows as result):
from: SELECT * FROM blog_articles WHERE fk_semikatagori_id = 9
to:
SELECT
english_navn
, english_tekst
FROM blog_articles
WHERE
fk_semikatagori_id = 9
Because you are using just these 2 columns into your loop but you are making MySQL engine get all columns from this table.
I hope it help you.
I have a page on my site that shows a member directory. I want the members to be listed 3 per row, before it goes to the next row. The code I have, does this for the very first row - but on the second row, its all on one line and doesnt carry down.
The profiles are showing up like this:
uuu
uuuuuuuuuuuuuuuuuuuuuuuuuuu
When they should be doing this:
uuu
uuu
uuu
uuu
This is what my code looks like:
<table>
<tr>
<td colspan="4"><h1>Member Directory</h1></td></tr>
<tr>
<td>
<?php
while($row = mysql_fetch_array($result)) {
if (empty($row['profile']) === false){
echo '<img src="', $row['profile'], ' "width="125">';
} else {
echo '<img src="../../images/template/avatar.png">';
}
echo '</td><td>';
echo '' . ucfirst($row['username']) . '<br />';
echo "Location: " . $row['location'] . "<br />";
echo '</td><td>';
if ($i++ == 2) echo '</td></tr><tr><td>';
}
?>
</td>
</tr>
</table>
Any help would be greatly appreciated, thanks!
Use
if (++$i % 3 == 0) echo '</td></tr><tr><td>';
Explanation:
First of all ++$i first increments $i, and then uses it in whatever is next, this makes for more readable code.
Second, the % is the modulus, which means it sortof subtracts 3 from $i until it is not possible anymore. E.g. 9 % 3 == 0, and 11 % 3 == 2 and so on. This means we know that we have printed 3 rows whenever $i % 3 equals 0.
try this one
<table>
<tr>
<td colspan="4"><h1>Member Directory</h1></td>
</tr>
<?php
$count=0;
while($row = mysql_fetch_array($result))
{
$count+=1;
if($count%3==1)
{
echo '<tr>';
}
echo '<td>';
if (empty($row['profile']) === false){
echo '<img src="', $row['profile'], ' "width="125">';
} else {
echo '<img src="../../images/template/avatar.png">';
}
echo '</td>';
echo '<td>';
echo '' . ucfirst($row['username']) . '<br />';
echo "Location: " . $row['location'] . "<br />";
echo '</td>';
if($count%3==0)
{
echo '</tr>';
}
}
if($count%3!=0)
{
echo '</tr>';
}
?>
</table>
You didn't reset the value of $i, so it kept increasing; another issue is that if you have only seven items, the last row should have four empty cells. So the loop condition needs to be augmented with a row completion status:
$i = 0;
while (($row = mysql_fetch_array($result)) !== false || $i != 0) {
if ($i == 0) {
echo '<tr>'; // start of new row
}
if ($row !== false) {
echo '<td>';
if (empty($row['profile'])) {
echo '<img src="', $row['profile'], ' "width="125">';
} else {
echo '<img src="../../images/template/avatar.png">';
}
echo '</td><td>';
echo '' . ucfirst($row['username']) . '<br />';
echo "Location: " . $row['location'];
echo '</td>';
} else {
echo '<td></td><td></td>'; // no more data
}
$i = ($i + 1) % 3; // advance
if ($i == 0) {
echo '</tr>'; // end of the row
}
}
I've been trying to figure out why my code, as simple as it is, does not work the way i want it to.
The problem i'm having is getting the correct values when trying to check sizeof() or count() on reversed simplexml array. I'm making a comments form that stores the comments to comments.xml, then reads the 5 newest comments and lists them newest on top, oldest on bottom.
What i have inside the comments.xml:
<root>
<entry>
<name>Admin</name>
<comment>Some nice comment</comment>
<postedOn>07.07.2013</postedOn>
<postedBy>***.***.***.***</postedBy>
</entry>
</root>
What i have inside my .php:
<?php
$xml = simplexml_load_file("comments.xml");
$reverseArray = (array) $xml;
$reverseArray = array_reverse($reverseArray["entry"]);
$limit = sizeof($reverseArray);
//$limit = count($reverseArray);
if($limit > 5){ $limit = 5; }
for ($i = 0 ; $i < $limit; $i++){
echo "<div class='panel'>";
echo "<span style='float: right;'>" . $reverseArray[$i]->postedOn . "</span>";
echo "<span style='float: left;'>" . $reverseArray[$i]->name . "</span>";
echo "<hr>";
echo $reverseArray[$i]->comment;
echo "<br></div>";
}
?>
Now the problem is, when i use this with only 1 entry inside comments.xml, it does not read it, and prints nothing on the page. Whenever i add another entry, it shows them both.
I also tried to add a "No comments yet."-code before the $limit-check:
if($limit == 0){ echo "<div class='panel'>No comments. :(</div>";}
And it was visible until the second comment was posted.
I hope someone could help me out with this, running out of ideas.
edit:
I tried to run the same code without reversing the array and it seems to be working just fine.
I managed to build a workaround since the sizeof()/count() did not work well with array_reverse, and here is what it looks like now:
<?php
$xmlfile = simplexml_load_file("comments.xml");
$limit = count($xmlfile->entry);
if($limit == 0){ echo "<div class='panel'>No comments. :(</div>";}
if($limit == 1){
echo "<div class='panel'>";
echo "<span style='float: right;'>" . $xmlfile->entry[0]->postedOn . "</span>";
echo "<span style='float: left;'>" . $xmlfile->entry[0]->name . "</span>";
echo "<hr>";
echo $xmlfile->entry[0]->comment;
echo "<br></div>";
}else{
$reverseArray = (array) $xmlfile;
$reverseArray = array_reverse($reverseArray["entry"]);
if($limit > 5){ $limit = 5; }
for ($i = 0 ; $i < $limit; $i++){
echo "<div class='panel'>";
echo "<span style='float: right;'>" . $reverseArray[$i]->postedOn . "</span>";
echo "<span style='float: left;'>" . $reverseArray[$i]->name . "</span>";
echo "<hr>";
echo $reverseArray[$i]->comment;
echo "<br></div>";
}
}
?>
So i had to make it process a single entry as non-reversed. Hope this helps others who struggle with this!
