| displaying random images with an appropriate caption [message #175931] |

Is there any way to write something that will choose not just a random
image but the random image and its caption as a pair?
This is my code for my random images as it exists now but,
unfortunately, it doesn't work very well if I don't have a caption
with the photo (even if just to credit the photographer):
<div style="float:right; width:363px;
margin: 1.0em 2.75em 1.0em 1.0em; padding: 0.25em;
text-align:center; background-color: #fff">
<?php
$dir="/library/images/slideshow";
$images = array("$dir/farm-640x480.gif" ,
"$dir/ranch-640x480.gif" ,
"$dir/plantation-640x480.gif");
$format=' <img src="%s"
class="rounded-corners"
style="width:360px;height:270px" />';
printf("$format", $images[array_rand($images)]);
echo "\n";
?>
</div>
Thanks for any help and/or suggestions.

I just want the captions in an array just like the filenames for the
images. I just don't know how to make the randomizer get the match
from each array.

I neglected to mention that I am not using MySQL or any other database
so I can't use that (at least not right now). Thanks.

Put it all on one line. Put that in a file. Each line will be an image
with the caption. Then use whatever randomizer you want to include a
line.

given two text files, one with a list of image paths and names based on
webroot, the other with a list of captions, so that 7th caption in the
caption file goes with the 7th url in the images file, and images and
captions are each listed on a single line in their respective files:
<?php
$flags = FILE_IGNORE_NEW_LINES | FILE_SKIP_EMPTY_LINES;
$captions = file("captionfile",$flags); // read array of captions, 1 per
line
$images = file("imagesfile", $flags); // read array of filenames, 1 per
line
$index = rand(0, count($captions)-1); // get a random index
$imgfile = $images[$index];
if (strpos($mgfile,"/")!==0) $imgfile = "/" . $imgfile;
$captiontext = ucwords($captions[$index]);
echo <<<EOT
<p style="text-align:center;margin:0 auto">
<img src="http://www.myhost.domain{imgfile}" alt="{$captiontext}"><br>
{$captiontext}</p>
EOT;
?>
imagesfile might contain:
---8<--- cut here ---8<---
/dir/dir/myface.jpg
/dir2/clown.jpg
lorry.png
/dir/dir3/cat.gif
/dir/dir3/dog.gif
---8<--- cut here ---8<---
captionfile might contain:
---8<--- cut here ---8<---
a mugshot, so if you see me you'll know me
my clown face
the lorry I drive
my pet cat
the dog next door
---8<--- cut here ---8<---

Hi Denis,
Thanks a bunch for your help. I liked your solution a lot and tried
to implement it with only partial success. Below is the URL for a
test page of what I have implemented with your code. The page
appeared blank until I commented out the here document. I also
implemented var_dumps on the variables to be sure I was getting
accurate data.
http://www.geol.ucsb.edu/graduate/aa.php
I also corrected a couple of syntax errors but mostly the code is
exactly as in your code above.
This is what is commented out:
//echo <<<EOT
//<p style="text-align:center;margin:0 auto">
//<img src="http://www.geol.ucsb.edu{$imgfile}" alt="{$captiontext}" /
>
//<br />
//{$captiontext}</p>
//EOT;
As you can see, it appears fine with the here doc commented. I just
can't see what is wrong with the here doc. Thanks for any further
help.

Yeah, I used $mages where I should have used $images, and missed the $
from {$imgfile} in the heredoc.

All the heredoc does is wrap the image and caption in a centered
paragraph, html 4.01 type markup. It was an example of how to output the
caption and image. Did you try it (a) without the style attributes (b)
using a div instead?
I wasn't trying to generate markup and css that would fit neatly into
your existing page layout, I was generating a standalone paragraph.
