Table with Columns

Jas0n · September 21, 2008

Hi Guys,

I'm currently trying to populate a table from reading images from a folder. Heres my code which works perfectly, however I would like to display the images like this:

a b c

e f g

h etc...

rather in this format of table..

a

b

c

d

e

f

g

etc...

I hope this makes sense!

<?php

$websiteurl = 'http://www.xxxxx.co.uk/beta/';
//$ProductCatFolder   = ;
//$ProductImageFolder = $product_info['products_model'];

$dir = "images/fascinators/mandy/";

// *********************************** Functions
function RemoveExtension($strName) 
{ 
     $ext = strrchr($strName, '.'); 

     if($ext !== false) 
     { 
         $strName = substr($strName, 0, -strlen($ext)); 
     } 
     return $strName; 
}  
// *********************************************

$dh = opendir($dir);

echo '<table width="450" border="0">';
while (($file = readdir($dh)) !== false) {

	$blah = $websiteurl.$dir.$file;
	$ProductColourName = RemoveExtension($file);
	$ProductColourName = ucwords($ProductColourName);

	if(($file != ".") and ($file != "..")) {

        	echo '<tr><td><img src="'. $blah .'" alt="'. $blah .'" name="'. $blah .'" width="147" height="146" /><br></td></tr>';
        	echo '<tr><td><a href="'. $blah .'">'. $ProductColourName .'</a><br></td></tr>';


	}

}
echo '</table>';
closedir($dh);

?>

Any help would be much appreciated!

Thanks again,

Jase

You can use modulus for this:

<?php
$string = "";
$cols = "";
if (!empty($_POST['words'])) {
$string = $_POST['words'];			//declare the $string variable passed from the "words" textarea
}
if (!empty($_POST['cols'])) {
$cols = $_POST['cols'];				//declare the $cols string passed from the "cols" textbox - defines the number of table columns to draw
}
$string = str_replace("'", '&#38;#39;', $string); 	//replace apostrophes with the equivalent SGML decimal character reference code (Standard Generalized Markup Language)
$string = stripslashes($string);		//remove the annoying automatic magic_quotes_gpc slashes set in php.ini 
?>

<html>
<head>
<title> </title>
<LINK REL="stylesheet" TYPE="text/css" HREF="../style.css" />

</head>
<body onLoad="document.maketable.cols.focus();">
Finishes the table when the array isn't perfectly divisible by the number of columns. 
<form action="" method="post" name="maketable">
Enter an array: 
<?php
if($string == '')
{
print "<textarea cols='60' rows='5' name='words'>For who would bear the whips and scorns of time, th' oppressor's wrong, the proud man's contumely, the pangs of despised love, the law's delay, the insolence of office, and the spurns that patient merit of th' unworthy takes, when he himself might his quietus make with a bare bodkin? Who would fardels bear, to grunt and sweat under a weary life, but that the dread of something after death, the undiscover'd country, from whose bourn no traveller returns, puzzles the will and makes us rather bear those ills we have than fly to others that we know not of?</textarea>";

Hi again,

Thanks for the quick replys!

Heres what I've tried, with using code from the "Multi-column Results" snippet.

<?php

$websiteurl = 'http://www.xxxxx.co.uk/beta/';
$dir        = "images/fascinators/mandy/";

// *********************************** Functions
function RemoveExtension($strName) 
{ 
     $ext = strrchr($strName, '.'); 

     if($ext !== false) 
     { 
         $strName = substr($strName, 0, -strlen($ext)); 
     } 
     return $strName; 
}  
// *********************************************

$dh = opendir($dir);

$i = 0;
    $max_columns = 3;

echo '<table cellspacing="3" cellpadding="3">';

while (($file = readdir($dh)) !== false) {

	$blah = $websiteurl.$dir.$file;
	$ProductColourName = RemoveExtension($file);
	$ProductColourName = ucwords($ProductColourName);

	if(($file != ".") and ($file != "..")) {

	   // open row if counter is zero
	   if($i == 0)
	   {
		  echo '<tr><td><img src="'. $blah .'" alt="'. $blah .'" name="'. $blah .'" width="147" height="146" /></td>';

	   // increment counter - if counter = max columns, reset counter and close row
	   if(++$i == $max_columns) 
	   {
		echo '</tr>';
		   $i=0;
	   }  // end if 
	   } // end while

	   // clean up table - makes your code valid!
	   if($i < $max_columns)
	   {
			for($j=$i; $j<$max_columns;$j++)
			echo '<td> </td>';
	   }
	   
        	//echo '<tr><td><img src="'. $blah .'" alt="'. $blah .'" name="'. $blah .'" width="147" height="146" /><br></td></tr>';
        	//echo '<tr><td><a href="'. $blah .'">'. $ProductColourName .'</a><br></td></tr>';
	}	
}
echo '</tr>';
echo '</table>';
closedir($dh);

?>

I'm not having much luck as only one image is appearing. Anyone have any ideas?

Thanks,

Jase

lool its soo easy to do:P


<?php

$websiteurl = 'http://****/';
//$ProductCatFolder   = ;
//$ProductImageFolder = $product_info['products_model'];

$dir = "img/";

// *********************************** Functions
function RemoveExtension($strName) 
{ 
     $ext = strrchr($strName, '.'); 

     if($ext !== false) 
     { 
         $strName = substr($strName, 0, -strlen($ext)); 
     } 
     return $strName; 
}  
// *********************************************

$dh = opendir($dir);
$i = 0;
echo '<table width="450" border="0"><tr>';
while (($file = readdir($dh)) && readdir($dh) !== false) {
if ($i % 3 == 0) {
$end = "</tr><tr>";
} else {
$end = "";
}
	$blah = $websiteurl.$dir.$file;
	$ProductColourName = RemoveExtension($file);
	$ProductColourName = ucwords($ProductColourName);

	if(($file != ".") and ($file != "..")) {

        	echo '<td><img src="'. $blah .'" alt="'. $blah .'" name="'. $blah .'" width="147" height="146" /><br></td>';
        	echo '<td><a href="'. $blah .'">'. $ProductColourName .'</a><br></td>';
	echo $end;


	}
$i++;				
}
echo '</table>';
closedir($dh);

?>

hope it helps

Just given your code a bash and it seems like its not displaying all of the images from the directory. Any Ideas?

Thanks for your reply,

Jase

Jas0n · September 21, 2008

Looks like only half of them

Minase · September 21, 2008

just remove " !== false " from while loop

Jas0n · September 22, 2008

Yup that fixed it!

just one more simple thing...

at the moment its doing this

a b

c d e

f g h

i j etc...

for some reason its not filling the first row. Any ideas?

Thanks again,

Jase
