images per row with an array

siobhan

I am trying to get 2 images per row to show up when I use an array to generate the image path to display. Can anyone help me?

I have the code below but I can't get the images per row to work.

Thanks
siobhan

<?
$name = $row_rs_dgame['name'];
$name2 = str_replace(' ', '', $name);
$path_array['imagefileanim'] = 'images/' . $name2 . '/' . $name2 . '/moving/' . $name2 . '_Anim_1.gif';

for ($i = 1; $i <= 4; $i++)
{
$path_array['imagefile' . $i] = 'images/' . $name2 . '/' . $name2 . '/screenshots/' . $name2 . '_' . $i . '.gif';
}

foreach ($path_array as $key => $value)
{
if (file_exists($value))
{
$imagesperrow=2;
$imagesperrow=$value
echo '<img src="'.$value.'">';

}
else
{
echo 'The file ' . $value . ' does not exist<br>';
}
}
?>

This part of code

$imagesperrow=2;
$imagesperrow=$value
echo '<img src="'.$value.'">';

beside of having an error (you need ; after second line) it does the following:

set variable $imageperrow to 2
set variable $imageperrow to value of the variable $value
echo the $value as a picture

I don't get what you tried here but if you need the pictures to show in rows of two pictures you should try something like this:

Implement an index variable like $ind and set it to 0, then in the foreach loop for every picture that is shown do $ind++;

When showing a pictures use table like this

before foreach loop set table:
echo "<table>";

inside foreach loop set how the pictures are shown:
if($ind%2==0){//$ind is 0, 2, 4...
echo "<tr><td>";
echo '<img src="'.$value.'">';
}
else{//$ind is 1, 3, 5...
echo "</td><td>";
echo '<img src="'.$value.'"></td></tr>';
}

and after foreach loop close table tag:
echo "</table>";

I didn't tested this code but it seems to me like t could work, well anyway you get my idea...

Any problem you just let me know...

Thanks! This makes heaps more sense now!

So, I've sorted out how to get the images into two rows. Now I just need an error statement so that if the image doesn't exist a broken link doesn't show up. In the code below as soon as I take the comments off the else statement, the images stop appearing. How do I get the else statement to work properly?

Thanks

$name = $row_rs_dgame['name'];
$name2 = str_replace(' ', '', $name);
$path_array['imagefileanim'] = 'images/' . $name2 . '/' . $name2 . '/moving/' . $name2 . '_Anim_1.gif';

for ($i = 1; $i <= 4; $i++)
{
$path_array['imagefile' . $i] = 'images/' . $name2 . '/' . $name2 . '/screenshots/' . $name2 . '_' . $i . '.gif';
}
echo '<table><tr>'."\n"; //phpcode
$imagesperrow=2;
$count=0;
foreach ($path_array as $key => $value)
{
if($count%$imagesperrow==0 && $count!=0)
echo '</tr><tr>'."\n";
echo '<td><img src="'.$value.'" border=0 align="left"></td>'."\n";
$count++;
}
//else {
//echo 'The file ' . $value . ' does not exist<br>';

//}

The if statement checks for following:
$count is 2,4,6...
and the else is if:
$count is 1,3,5...

I don't know why you did that but to check whether the file exists best is to use
file_exists

Okay, things seem to make sense when i do them, then looking back... ugh.

I've tried adding in a file exists (see below) but that doesn't get the desired result either (well, the way I have written it🙂

But I think the real problem is I don' t understand what the problem is. I have two issues really see: http://www.ginzagames.com/gamedisplayinclude3.php?recordID=5001 for what I mean. The first is the broken image--how do I get that from showing up? I don't think file_exists is what I want to use? The second is how do I change the code below to have 2 images in a row unless the pics are more than 450 pixels then only 1 image per row.

Thanks for all of your help.
