How do insert array results into columns?

ShenPixel

I've been working with the following code and would like to output the results into a customizable column variable, how would I go about doing such a thing, thanks in advance for any help. I hard coded the columns in the code below, but I would like the variable to be set so that a new row will start after a set number of columns.

Expand|Select|Wrap|Line Numbers

 
<?

$allfiles = scandir('.');

$goodfiles = array();

foreach($allfiles as $f){

    if(strpos($f,'.')!==0){

        array_push($goodfiles,$f);

    }

}

$pages = array_chunk($goodfiles, 10);

$columns = 2;

$pgkey = (int)$_GET['showpage']; // forces $_GET['showpage'] to be an integer

$pages[$pgkey];

echo "<table border='0' cellpading='2' cellspacing='2' align='center'><tr>";

foreach($pages[$pgkey-1] as $file){ echo '<td align=center><img src=files/'.$file.'></td>'; 

}

echo "</tr></table>";

 ?>

<? for($i=1; $i< count($pages)+1; $i++): ?>

     <a href="index.php?showpage=<? echo $i;?>"><? echo $i; ?></a>

<? 

endfor;

?>

This loops needs modifying

 foreach($pages[$pgkey-1] as $file){ echo '<td align=center><img src=files/'.$file.'></td>';  

}

You simply need a column tally of how many columns have been written.
When the set amount is reached, start a new row then reset the tally.

Or you could use a for loop which already has a tally.
Then check if the loop tally is an exact multiple of the set value, if so start a new row.

Thanks, I thought that was the problem, but I cannot wrap my head around it, I've tried the following for loop, I know I'm missing something simple.

Expand|Select|Wrap|Line Numbers

 
for($i = 0; $i < $per_page; $i++) 

{
 
  if($i % $columns == 0 and $i != 0) 

  {

    echo "</tr><tr>";

  }
 
  # Add a column

echo "<td align='center'><img src=files/'.$file.'></td>";

}

This looks alright. What is happening when used?
Don't forget to open the very first row and close the last as in the first post <table><tr>

thanks again, when I insert the for loop, I get pagination and a table with no columns.

<table border='0' cellpading='2' cellspacing='2' align='center'>

<tr></tr>

</table>

This is what my combine script looks like:

<?

$allfiles = scandir('.');

$goodfiles = array();

foreach($allfiles as $f){

    if(strpos($f,'.')!==0){

        array_push($goodfiles,$f);

    }

}

$pages = array_chunk($goodfiles, 10);

$columns = 2;

$pgkey = (int)$_GET['showpage']; // forces $_GET['showpage'] to be an integer

$pages[$pgkey];

echo "<table border='0' cellpading='2' cellspacing='2' align='center'><tr>";

foreach($pages[$pgkey-1] as $file){ 

for($i = 0; $i < $per_page; $i++) 

{

   if($i % $columns == 0 and $i != 0) 

   {

     echo "</tr><tr>";

   }
 
# Add a column

echo "<td align='center'><img src=files/'.$file.'></td>";

}

}

echo "</tr></table>";

 ?>

<? for($i=1; $i< count($pages)+1; $i++): ?>

     <a href="index2.php?showpage=<? echo $i;?>"><? echo $i; ?></a>

<? 

endfor;

?>

An empty array and/or empty variables is the problem.
Echo out their contents when testing to help yourself.
For example what is the value of $per_page?
what is in $pages?
is there a value in $pgkey?

I changed:

Expand|Select|Wrap|Line Numbers

 
foreach($pages[$pgkey-1] as $file){ 

for($i = 0; $i < $per_page; $i++) 

 {

   if($i % $columns == 0 and $i != 0) 

   {

     echo "</tr><tr>";

  }

to

Expand|Select|Wrap|Line Numbers

 
foreach($pages[$pgkey-1] as $file){ 

for($i = 0; $i < $pages[$pgkey]; $i++) 

{

   if($i % $columns == 0 and $i != 0) 

   {

     echo "</tr><tr>";

   }

$per_page was empty and now I get an endless loop with two columns but one image

I feel like pulling my hair out lol I know it's something simple I'm overlooking/leaving out.

code green

Expand|Select|Wrap|Line Numbers

 foreach($pages[$pgkey-1] as $file){  

for($i = 0; $i < $pages[$pgkey]; $i++)

In the second loop the contents of the current $pages element is used as the loop limit.
That is why it is hanging.
$i < must be an integer.
Do you mean $pgkey?
