increment an array element to display jpg's ...

#1 (**permalink**) 02-01-2004

I'm reading a directory of pictures , and trying to display them nicely
formated in a table 4 accross...
a few issues ..

My play with array's don't work ...I'm able to feed pictures into array's
,with
$thefiles[$c] = $file;

but when I try to call the pictures
echo "<img src=\"\\images\\$thefiles[$c]\" width='142'height='142'>";
works but

thefiles[$c+1]

bombs ! If I can't manually increment the array I don't see how to do this
..

the whole thing at the moment is:

<html>
<head>
<title>PHP Test</title>
</head>
<body>

<?php

$mydir = dir('images');
?>
<?php $thefiles=array(); ?>
<?php echo '<table border="3">'; $c=0 ?>

<?php

while(($file = $mydir->read()) !== false) {

$c=$c+1 ; // echo $c;
$d=($c+=2);
$thefiles[$c] = $file;

echo '<tr>';
echo '<td>';
// echo "<img src=\"\\images\\$file\"
width='142'height='142'>";
// echo "<img src=\"\\images\\$file\"
width='142'height='142'>";
echo "<img src=\"\\images\\$thefiles[$c]\"
width='142'height='142'>";
echo "<img src=\"\\images\\$thefiles[$d]\"
width='142'height='142'>";
//echo "<img
src=\"\\images\\$thefiles[$c(+2)]\" width='142'height='142'>";
// $c=$c+1 ; echo $c;
echo $c;

echo '</td>';
echo '</tr>';

}
echo '</table>';
$mydir->close();

?>
<p> test</p>

</body>
</html>

I played around for a few minutes and made an example for you, I think this
captures what you want to do....

http://ghost.3drealm.net/imagetable.php

<?php
// just setting a path variable to simplify writing
$path = "puppies/images/puppies/";
// how many columns do you want? can be set to whatever
$cols = 4;

$mydir = dir($path);

$lines = "<table border=3>\n";

while ($file = $mydir->read())
{
$fullpath = $path.$file;
if (GetImageSize($fullpath))
{
// Increment $c up 1 each cycle thru
$c++;
// If this is the first entry on the row start the table
row.
if ($c == 1) { $lines .= "<tr>\n"; }
$lines .= "<td><img src='$fullpath' width=150></td>\n";
// If this is the last column close the row and set $c to 0
if ($c == $cols) { $lines .= "</tr>\n"; $c = 0; }
}
}
// now finish out the table columns just to be complete
if ($c < $cols)
{
$colstogo = $cols - $c;
$lines .= "<td colspan=$colstogo> </td>\n";
}
// and add in the closing tag to make netscape happy.
$lines .= "</table>";
echo $lines;
?>

This is the un*x version, freebsd actually, so the file pathing is different
but the code should work just the same.

I would first read the dir, put all the images into the array:

$mydir = dir('images');
$thefiles = array();
while(($file = $mydir->read()) !== false) {
if ( is_file ( $file )) {
// might want to check if it's really images
// and not text, or something else
$thefiles[] = $file;
}
}
$mydir->close();

Then format and print the table.

foreach ( $thefiles as $value ) {
// table stuff
echo "<img src='$value' width='142'height='142'>\n";
// table stuff
}
