I want to set every first and second tr with a different class.
With my code I only get "odd" on every tr.
Does anyone knew what is wrong?
$rowCount = 0;
if ($rowCount++ % 2 == 1 ) :
echo "<tr class='even'>";
else:
echo "<tr class='odd'>";
endif;
try this one (keep the $rowCount setting outside the loop):
for($row = 0; $row < $rowTotal; $row++)
{
echo "<tr class='".($row % 2 ? "even" : "odd")."'>";
}
Your logic implementation is going in wrong direction
$rowCount = 0;//This was always initializing your count to 0
Resulting always odd class added
Change it to this:
for ($rowCount = 0;$rowCount<$total; $rowCount++) {
if ($rowCount % 2 == 1 ) :
echo "<tr class='even'>";
else:
echo "<tr class='odd'>";
endif;
}
OR you can simply use ternary operator as
for ($rowCount=0; $rowCount<$total; $rowCount++) {
echo "<tr class='".($rowCount % 2 == 0 )?'odd':'even'."'>";
}

I'd like to fill a table vertically. For example one name on one row, the age on the second row alternately, and limit the table to 4 columns:
Is this possible with this kind of code?
Here is my Code:
<?php
$age = array("26","16","17","19","24","30");
$name = array("adam","andrew","tim","mike","don","eddy");
echo "<table border=1>";
for($i=0;$i<count($age);$i++)
{
if ($i > 0 && $i % 4 == 0)
{
echo "</tr><tr>";
}
echo "<td>";
echo $name[$i];
echo "</td>";
echo "<td>";
echo $age[$i];
echo "</td>";
}
echo "</tr>";
?>
Please try this. It is not the most elegant way but will give you an idea and maybe improve your answer. I will suggest you maybe use multi-dimensional array to store age and name together.
$age = array("26","16","17","19","24","30");
$name = array("adam","andrew","tim","mike","don","eddy");
$ageChunks = array_chunk($age, 4); //divide age array into chunks of 4
$nameChunks = array_chunk($name, 4); //divide name array into chunks of 4
//print table data
function printData($td)
{
echo "<td> ".$td." <td>";
}
//print table row. Assumption here is $nameChunks and $ageChunks are same length.
function printRow($nameChunks, $ageChunks)
{
foreach ($nameChunks as $key=>$val) {
echo "<tr>";
array_map("printData", $nameChunks[$key]);
echo "</tr><tr>";
array_map("printData", $ageChunks[$key]);
echo "</tr>";
}
}
//print table
function printTable($nameChunks, $ageChunks)
{
echo "<table>";
printRow($nameChunks, $ageChunks);
echo "</table>";
}
printTable($nameChunks, $ageChunks);
you need to change condition
if ($i > 0 && $i % 4 == 0) to if ($i > 0 && $i % 2 == 0) because you print 2 columns per iteration
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 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>";
please i need you help with my script.. I'm trying to echo some content of query into an html table, but i want to break it at every 7th parameter. The script below only breaks the first seven, while the rest are not broken up at interval and they were also echoed out of the html table.
How can I do this please. Thank you for your time and help.
echo "<table class=\"altrowstable\" bgcolor = gold >\n";
$count = 0;
echo "<tr align= \"center\">\n";
$carry_over = array();
$score_count = mysql_numrows($query8);
echo "<td>" . "Failed: ";
if ($score_count !== 0) {
while ($row8 = mysql_fetch_assoc($query8)) {
echo "<th>" . $row8['course_code'] . "</th>";
if ($count == 7) {
echo "</tr>\n";
echo "</table>";
}
}
}
Use modulo operator instead of equality
if ( ($count+1) % 7 ){
The +1 is there so that it doesn't break immediately on $count == 0 because 0%n is 0
You need to use the modulus operator %, which returns the remainder after division. $count % 7 ==0 means the current count is on a multiple of 7, and you should break. You also need to increment $count.
echo "<table class=\"altrowstable\" bgcolor = gold >\n";
$count = 0;
echo "<tr align= \"center\">\n";
$carry_over = array();
$score_count = mysql_numrows($query8);
echo "<td>"."Failed: ";
if($score_count !== 0){
while ($row8 = mysql_fetch_assoc($query8)) {
echo "<th>".$row8['course_code']."</th>";
// Increment $coutn
$count++;
// Check the modulus
if ( $count % 7 == 0 ){
echo "</tr>\n";
echo "</table>";
}
}
}
So basically I have a script that is suppose to display my code into rows of 3, and create a new row. However, it is all displayed in one column. Here's the code.
while($mysql2 = mysql_fetch_array($sql2)) {
$prodlogo = $mysql2['logo'];
$prodid = $mysql2['id'];
$prodname = $mysql2['name'];
$x = 1;
if($x==1) {
echo "<tr>";
}
echo "<td><img src=images/productpics/$prodlogo></br><a href=viewproduct.php?pid=$prodid>$prodname</a></td>";
$x++;
if($x==3) {
echo "</tr>";
$x = 1;
}
}
move the $x out of the loop,otherwise you are reset it to one in every loop
each <td> will be a separate column. I would suggest you format it thus.
while($mysql2 = mysql_fetch_assoc($sql2)) {
foreach($mysql2 as $row) {
echo "<tr>";
echo "<td>".$row['logo']."</td><td>$".row['id']."</td><td>".$row['name']."</td>";
echo "</tr>";
}
}
also you need to use mysql_fetch_assoc() to get an associative array you can access like $row['key']
You may need to instantiate $x = 1 outside of your while loop - you're resetting it to 1 each time you're running it.
Using modulo might be good too:
if (($x % 3) == 0) {
echo "<tr>"
}
echo "<td><img src=images/productpics/$prodlogo></br><a href=viewproduct.php?pid=$prodid>$prodname</a></td>";
if (($x % 3) == 0) {
echo "</tr>"
}
You wouldn't need to worry about resetting $x to 1...
