gallery - do loop

[wilbur]

Hi,

I'm writing a gallery and having a few problems: I have three pages. Main Gallery, Sub Gallery, Picture.

I'm having problems with the sub gallery - writing the session variable as the final picture name in the loop as follows:

<?php

do { ?>
<a href=<? $_SESSION['final_picture'] = $row_Recordset1['thumb_loc']; ?>"main_gallery.php"><img src="<?php echo $row_Recordset1['thumb_loc']; $main_picture[] = $row_Recordset1['thumb_loc'] ?>" alt="" name="image" border="0"></a>

<?php } while ($row_Recordset1 = mysql_fetch_assoc($Recordset1)); ?>

Can anyone suggest a way simply to take a variable produced to the final page. All it seems to do is write the session variable as the last record in the group. I can understand why it is doing this - but I need a way around to take a specific variable to the final page based on the output of the do loop above.

I hope this is clear.

Any suggestiions welcomed,

thanks,

w.

I... don't understand what you mean by specific variable, but you could use an array like
$_SESSION['final_picture'][$var] = $row_Recordset1['thumb_loc'];
and at the end of the loop increment $var by going $var++.

Thanks,

but as I see it - and please remember I'm a beginner. That code would simply create a number of session variables of the picture names. How would the final page be created viewing just the single picture. Ie. once the session variables have been created how do I get the final page to recognise which one has been clicked on and then display it on the final page???

I'm stumbling along at the moment, just trying to get this part figured out - but I'm sure there must be some way around it.

Any ideas,

W.

I don't know what the final page exactly is supposed to do... The last sentence in your last post looks like you'd pass a GET var in, right? So, I think it might be like:

<?php
do { ?>
<a href="main_gallery.php?pic=<? echo(urlencode(($row_Recordset1['thumb_loc'])); ?>"><img src="<?php echo $row_Recordset1['thumb_loc']; $main_picture[] = $row_Recordset1['thumb_loc'] ?>" alt="" name="image" border="0"></a>

<?php } while ($row_Recordset1 = mysql_fetch_assoc($Recordset1)); ?> 
[code=php]

I'm kinda guessing.

thanks Stick Figure,

it worked. Can you tell me where I can read about defining PHP in the main URL, as per the example that you posted below or simply give me a term I can search for.

http://216.99.97.187/~lmphoto/main_gallery.php?pic=images%2Ffullpictures%2Fpromotional%2Fthumbs%2Falumnae.jpg

or... If I have the above URL, how do I display the picture. Is the variable name simply 'pic'?

It might be easy, I'm about to have a play with the code, and I'll update this if I get it solved. Thanks.

Solved thanks with stick_figures code. All is now working.
