PHP image gallery

[servvs]

Ok so heres the deal, I want a lightweight image gallery that reads from a specified directory. I have started working on one but I just can't get past one thing. I am not really sure what I am doing wrong. I have it list the pictures correctly but when I try to modify them into a table or div so I can start working on a simple template it screws up horribly. No matter what I make the width of the table or div the pictures just stay in one line and go all the way across the screen. Here is my script w/o the div/table

 

<?php

$d = dir("./");
$pattern="(\.gif$)|(\.jpg$)|(\.png$)|(\.jpeg$)|(\.gif$)";

while (false !== ($entry = $d->read()))
{
if(eregi($pattern, $entry))
   echo '<a border="0" href="index.php?image='.$entry.'"><img border="0" width="100" height="100" src="'.$entry.'"</a>';
}

if (is_null($HTTP_GET_VARS['image'])){ 
$image = "<img src='1-dna005.jpg'> ";
} else {
$image = "<img src='$HTTP_GET_VARS[image]'><br>{$HTTP_GET_VARS['image']}";
}

echo "$image";

$d->close();


?>

 

and here it is with a div/table

 

<?php

$d = dir("./");
$pattern="(\.gif$)|(\.jpg$)|(\.png$)|(\.jpeg$)|(\.gif$)";

echo '<table width="500"><tr><td>';

while (false !== ($entry = $d->read()))
{
if(eregi($pattern, $entry))
   echo '<a border="0" href="index.php?image='.$entry.'"><img border="0" width="100" height="100" src="'.$entry.'"></a>&nbsp';
}

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

if (is_null($HTTP_GET_VARS['image'])){ 
$image = "<img src='1-dna005.jpg'> ";
} else {
$image = "<img src='$HTTP_GET_VARS[image]'><br>{$HTTP_GET_VARS['image']}";
}

echo "$image";

$d->close();


?>

Interesting that you're working on one too. I'm just finishing up the first version of mine.

lol, hows yours turning out flying? I can't get mine to work right for some reason, any help would be awesome

[FlyingIsFun1217]

Well, I'm too ADD to look through your code much, but when you say that you are trying to list it in a table (also something I'm working on), and that they just shoot horizontally accross the screen, it leads me to believe that you have forgotten that you need to start a new row (<tr>) and a new data cell into it (<td>). This is all assuming that you are trying to get it to go vertically (the listings).

Well, the html is fine. What I am trying to do is make it display like 5 across and then start a new row dynamically.

Here is what I use to make a dynamic table:

 

columnLimit is how many columns across you want obviously.

 

<?php
$table = "<table width=\"0\" border=\"0\" cellspacing=\"5\" cellpadding=\"5\">\n";
$table .= "<tr>\n";
$count = 0;
$columnLimit = 5;
while($row = mysql_fetch_array($sql)) {
$count += 1;
if($count == $columnLimit) {
	//if your at the last columd, add a new row
	$table .= "<td>your image</td>\n";
	$table .= "</tr>\n<tr>\n";
	$count = 0;
} else {
	//else just add a new cell
	$table .= "<td>your image</td>\n";
}
}
if($count != $columnLimit) {
$table .= "</tr>\n";
}
$table .= "</table>\n";
echo $table;
?>

I am trying to do this w/o the use of any databases, I just want it to read from the directory

[rondog]

then make the while loop a for loop and have it loop X amount of times depending on how many images are in that directory

[servvs]

Yeah, im not too entirely sure what to do with that lol. I am still learing php as a language so I am not used to a lot of things.

[rondog]

you can use this to count how many files are in your folder:

<?php 
$dir = '/path/to/directory/'; 
$filecount = 0; 
$d = dir($dir); 
while ($f = $d->read()) { 
if(($f!= ".") && ($f!= "..")) { 
	if(!is_dir($f))
	$filecount++;
} 
} 
echo 'there are ',$filecount,' files in this folder'; 
?>

 

now $filecount is the variable you use for your for loop so like this:

<?php
$dir = '/path/to/directory/'; 
$filecount = 0; 
$d = dir($dir); 
while ($f = $d->read()) { 
if(($f!= ".") && ($f!= "..")) { 
	if(!is_dir($f))
	$filecount++;
} 
} 
$table = "<table width=\"0\" border=\"0\" cellspacing=\"5\" cellpadding=\"5\">\n";
$table .= "<tr>\n";
$count = 0;
$columnLimit = 5;
for($i = 0; $i<=$filecount; $i++) {
$count += 1;
if($count == $columnLimit) {
	//if your at the last columd, add a new row
	$table .= "<td>your image</td>\n";
	$table .= "</tr>\n<tr>\n";
	$count = 0;
} else {
	//else just add a new cell
	$table .= "<td>your image</td>\n";
}
}
if($count != $columnLimit) {
$table .= "</tr>\n";
}
$table .= "</table>\n";
echo $table;
?>

[servvs]

so it should look something like this

 

<?php
$dir = './'; 
$filecount = 0; 
$d = dir($dir); 
while ($f = $d->read()) { 
if(($f!= ".") && ($f!= "..")) { 
	if(!is_dir($f))
	$filecount++;
} 
} 
$table = "<table width=\"0\" border=\"0\" cellspacing=\"5\" cellpadding=\"5\">\n";
$table .= "<tr>\n";
$count = 0;
$columnLimit = 5;
for($i = 0; $i<=$filecount; $i++) {
$count += 1;
if($count == $columnLimit) {
	//if your at the last columd, add a new row
	$table .= "<td>$f</td>\n";
	$table .= "</tr>\n<tr>\n";
	$count = 0;
} else {
	//else just add a new cell
	$table .= "<td>$f</td>\n";
}
}
if($count != $columnLimit) {
$table .= "</tr>\n";
}
$table .= "</table>\n";
echo $table;
?>

 

Im still not getting it, lol
