starting a new row after php has made 5 columns

joshd963

Ok, so thanks to cretaceous, i have the following code..

<?php
if ($handle = opendir('shared/files/')) {
    while (false !== ($file = readdir($handle))) {
        if ($file != "." && $file != "..") {

$break = pathinfo($file);
$b = $break['extension'];

switch (@$break[extension]) { 
case 'bmp' : 
    echo 'A BMP<br>'; 
    break; 

case 'png' : 
    echo 'A PNG<br>'; 
    break; 

case  'doc' : 
case 'docx' : 
    echo 'A DOC OR DOCX<br>'; 
    break; 

default: 
     echo 'FILE NOT RECOGNISED<br>'; 

} 
        }
    }
    closedir($handle);
}
?>

So now i would like to... after 5 files have been called... (each "echo" will have a <TD> in it) so.. after 5 <TD>s i would like to make a <TR> so its not just one big row. is there any way to do this? Many thanks...😃

Use the modulus operator. Quick example:

for($i=1; $i <= 20; $i++)
{
  echo "$i ";

  if($i % 5 == 0)
    echo "\n";
}

you are a man of legend! yes sir thank you sir!

joshd963

thank you. I now have the following code:

<?php 
echo "<table><tr>";
for($i=1; $i <= 20; $i++) 
{ 
echo "<td>";
  if ($handle = opendir('../../shared/files/')) {
    while (false !== ($file = readdir($handle))) {
        if ($file != "." && $file != "..") {

$break = pathinfo($file);
$b = $break['extension'];

switch (@$break[extension]) { 
case 'bmp' : 
    echo 'A BMP<br>'; 
    break; 

case 'png' : 
    echo 'A PNG<br>'; 
    break; 

case  'doc' : 
case 'docx' : 
    echo 'A DOC OR DOCX<br>'; 
    break; 

default: 
     echo 'FILE NOT RECOGNISED<br>'; 

} 
        }
    }
    closedir($handle);
}
echo "</td>";

  if($i % 5 == 0) 
    echo "</tr><tr>"; 
} 
echo "</tr></table>";
?>

But this is just doing the "a bmp" or whatever.. for every file.. in each cell, twenty times...
so.. i have twenty duplicate cells on four rows, with five columns. I dont quite understand this modules thing - i was wondering if you had any links to documentation on it so i can customise it.. or perhaps you could kindly help me 🙂😕🙂

im not sure how to edit my message. But umm, what i would like to do.. is have each file in a different cell 😮.

Brad was showing you an example - you need to try to figure out what it is doing before cutting and pasting !

the while function is the key to this ..
as that iterates around you need to do the add table cell stuff
try this:

echo "<table><tr>";


  if ($handle = opendir('../../shared/files/')) {
    while (false !== ($file = readdir($handle))) {
        if ($file != "." && $file != "..") {
            $i++;
 echo "<td>";       

$break = pathinfo($file);
$b = $break['extension'];

switch
(@$break[extension]) {
case 'bmp' :
    echo 'A BMP<br>';
    break;

case 'png' :
    echo 'A PNG<br>';
    break;

case  'doc' :
case 'docx' :
    echo 'A DOC OR DOCX<br>';
    break;

default:
     echo 'FILE NOT RECOGNISED<br>';

}
echo "</td>";
 if($i % 5 == 0) echo "</tr><tr>";
}
    }
    closedir($handle);
}

echo "</tr></table>";

ah yes! This code works very well! Thank you Cretaceous. I did have a little trouble understanding the other code... But now i have seen two examples of its function.. i think i understand. I am going to have a play to become more familiar with this.

Once again thanks & regards
