[RESOLVED] Creating a variable from a switch or elseif statement.

[nawrik]

Hello,

my first post on PHPBuilder, I'm new to PHP so be easy on me!

I think I know what I'm trying to do, the problem is I just don't know how to do it!

All help/advice appreciated...

I'm writing a basic php page which will display a large image and 12 thumbnails all on the same page.

The page is template based, so the thumbnails will be static links coded into the table - the link calls the image like so: index.php?page=portfolio&image=001

I have managed to make the template so the variable $image loads up the unique image requested after the equals sign.

Also below the image there will be a unique caption printed relevant to the image called forward, I have created using a simple switch statement:

<?php
switch ($image)
{
case 001:
  echo "This is the picture caption for image 001";
  break;
case 002:
  echo "This is the picture caption for image 002";
  break;
case 003:
  echo "This is the picture caption for image 003";
  break;
default:
  echo "Please click on a thumbnail";
}
?>

But now comes my problem...

...I am trying to create the variable $caption that can be taken from the individual echo's above and placed in the alt="" tag when loading the $image.

This way, rather than having a generic alt tag for all 12 images (which is fine, but not good enough!) I can have a unique alt tag for each image and of course making it more relevant and accessible for all.

Thankyou in advance

store the captions in an array:

$captions = array(
'001' => 'This is the picture caption for image 001',
'002' => 'This is the picture caption for image 002',
'003' => 'This is the picture caption for image 003'
);

echo $captions[$_GET['image']];

That worked perfectly, thankyou devinemke!!
I successfully replaced my switch statement with the array...
However one more question, how do I place the $captions within the alt tag?

<?php echo "<img src='$image.jpg' alt='?????'>"; ?>

<?php echo "<img src='$image.jpg' alt='{$captions[$image]}'>"; ?>

Kudose,

thankyou...I did figure my own workaround (after about an hour)...

...it went like this:

$imgalt = $captions[$_GET['image']];

and then I called the variable $imgalt.

However your option is much cleaner and my code was promptly changed. thankyou for your help.

P.S I'm loving these PHP shenanigans!
