Help with php

    Hello,

    I don’t really know php, I just work with what I can from others, copying and pasting and slowly understanding things. I have got this far with a link:

    <a href="<?php echo $image->imageURL ?>" title="<h7><?php echo $image->alttext ?></h7><h8>&nbsp;&nbsp;|&nbsp;&nbsp;<?php echo $image->description ?></h8>" <?php echo $image->thumbcode ?> >
				<?php if ( !$image->hidden ) { ?>
				<img title="<?php echo $image->alttext ?>" alt="<?php echo $image->alttext ?>" src="<?php echo $image->thumbnailURL ?>" <?php echo $image->size ?> />
				<?php } ?>
			</a>

    (The reason I have h7 etc. inside a title is that the title is used by a script – shutter. It’s for making a photo gallery.)

    It’s doing everything nicely, unless $image->description is empty. Then I get alttext followed by |. If the description is empty, I don’t want the | to display.

    I guess this is pretty easy to do, if you know php? Something to do with ‘if’?

    There’s no such tag as H7 in HTML.

    There’s no such tag as H7 in HTML.

    Erm, really? Ok, well I’ll change them to h5 and h6. Actually, the code didn’t validate, so I changed the ‘<‘ etc. to the html code. It validates fine now.

    I’d still like help making the little php ‘if’ bit. I only want [code]??|??<?php echo $image->description ?>[/code]
    if $image->description is not empty.

    Will this be difficult? To reiterate:

    If the the description field is empty, I want to echo nothing. If it is not empty, I want to echo something. How do I do that with php?

    Thanks to anyone that can help me here… ??

    <?php if ( $image->hidden ) :?>
<a href="<?php echo $image->imageURL; ?>" title="<?php echo $image->alttext; ?> <?php echo $image->descriptio;n ?>" <?php echo $image->thumbcode; ?> ><img title="<?php echo $image->alttext; ?>" alt="<?php echo $image->alttext; ?>" src="<?php echo $image->thumbnailURL; ?>" <?php echo $image->size; ?> /></a>
<?php endif;?>

    Thank you for posting. Forgive me if I have misunderstood.
    You’ve started with $image->hidden, but I’m not using any hidden images. Hidden images are part of NextGen gallery, for images you don’t want to be displayed, I believe.

    I will try to explain better.

    Sometimes <?php echo $image->description ?> gives me nothing; there is no description for the photograph. If there is no description, I want:
    <a href="<?php echo $image->imageURL ?>" title="<?php echo $image->alttext ?>" <?php echo $image->thumbcode ?> >

    But if there IS a description, I want:
    <a href="<?php echo $image->imageURL ?>" title="<?php echo $image->alttext ?>&nbsp;&nbsp;|&nbsp;&nbsp;<?php echo $image->description ?>" <?php echo $image->thumbcode ?> >

    <?php if( $image->description ) :?><a href="<?php echo $image->imageURL ?>" title="<?php echo $image->alttext ?>&nbsp;&nbsp;|&nbsp;&nbsp;<?php echo $image->description ?>" <?php echo $image->thumbcode ?> >
<?php else :?> <a href="<?php echo $image->imageURL ?>" title="<?php echo $image->alttext ?>" <?php echo $image->thumbcode ?> >
<?php endif;?>

    Sorry for the delay in testing this.

    I’ve copied and pasted as is, and unfortunately it is still inserting the ‘|’, even when there is no description.

    Basically, it is always using the first line, and never what follows <?php else :?>.
