PHP dynamically changing div issue - php

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.

Can anyone suggest me how should i get this output.
Check below snippet,

$temp = $inc;
if ($inc == 4) {

$i++;
}
if ($i == $inc) {
echo "</div>";
if ($i == 3) {

$i = 1;
$inc = ($inc == 4 ? 3 : 4);
}
}

Dynamic Table Continuous <td> Count

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 while numbers in each row

<?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.

PHP members page carrying down to new line

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
}
}

PHP XML reversed array sizeof() and count() returns incorrect values

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!
