I’m having some trouble with my webcomic; it’s the last part of the comic that needs help.

I have an area where comics are listed by subject (beer, cars, school, etc.).

What I hope to have is for the comics to show up like this:

PAGE 1
<ul>
<li><img src=”beer1″></li>
<li><img src=”beer2″></li>
<li><img src=”beer3″></li>
<li><img src=”beer4″></li>
<li><img src=”beer5″></li>
</ul>

PAGE 2
<ul>
<li><img src=”beer6″></li>
<li><img src=”beer7″></li>
<li><img src=”beer8″></li>
<li><img src=”beer9″></li>
<li><img src=”beer10″></li>
</ul>

Note: each comic used in these lists is actually NAMED, rather than numbered.

The following is my PHP array:

[code=php]<?php include(“./inserts/head.htm”); ?> <link type=”text/css” rel=”stylesheet” href=”./setup.css”> <title>Random Subjects</title> </head> <body> <h1>BEER</h1> <ul class=”comics”> <?php $page = (isset($_GET[‘page’])) ? $_GET[‘page’] : 1 # default is page 1 $comics = file(beer_list.array); for($ix = $page * 5 – 5; $ix < $page * 5 and array_key_exists($ix, $comics); $ix++) { echo “<li><img src='{$comics[$ix]}’ alt=’comic’></li>n”; # add style etc. as desired } # previous/next stuff if($page > 1) { echo “<a href=’comics.php?page=” . $page – 1 . “‘>Previous page</a>n”; } if(count($comics) >= $page * 5) { echo “<a href=’comics.php?page=” . $page + 1 . “‘>Next page</a>n”; } ?> [/code]

And this is the file mentioned (beer_list.array)

[CODE] ../../comics/y1-sem1/badinfluence.gif ../../comics/y1-sem1/beerfrat.gif ../../comics/y1-sem1/homework.gif ../../comics/y1-sem1/officerpete.gif ../../comics/y1-sem1/pocketsized.gif ../../comics/y1-sem1/project.gif ../../comics/y1-sem1/sober.gif ../../comics/y1-sem1/sucker.gif ../../comics/y1-sem2/drunk.gif ../../comics/y1-sem2/derive.gif ../../comics/y2-sem2/alcoholic.gif ../../comics/y3-sem2/alkydonow.gif ../../comics/y3-sem2/drunkcrit.gif ../../comics/y3-sem2/walk.gif[/CODE]

What I get is the following error message:

~~[QUOTE]~~

Parse error: syntax error, unexpected T_VARIABLE in C:apachefriendsxampphtdocs!my_pages!coachrandomcollectionssubjectsbeer.php on line 10

[/QUOTE]

Where am I goofing up? Line 10 reads ~~[i]~~$comics = file(beer_list.array);[/i]

@Bootsman123Jul 31.2005 — #This

[code=php]
 $page = (isset($_GET['page'])) ? $_GET['page'] : 1 # default is page 1
 $comics = file(beer_list.array);
 [/code]

Should be:

[code=php]
 $page = (isset($_GET['page'])) ? $_GET['page'] : 1; # default is page 1
 $comics = file("beer_list.array");
 [/code]

@NogDogJul 31.2005 — #

[code=php]
 $comics = file("beer_list.array");
 [/code]

@Mr_Initial_ManauthorAug 01.2005 — #Thank you. ?

Secondly, my end links are screwy.

[code=php]<?php include("../../inserts/head.htm"); 
 echo ("<link type="text/css" rel="stylesheet" href="../../setup.css">
 <title>Random Subjects</title>
 </head>
 <body>
 <h1>BEER</h1>
 <ul class="comic">");
 $page = (isset($_GET['page'])) ? $_GET['page'] : 1; # default is page 1
 $comics = file("beer_list.array");
 for($ix = $page * 5 - 5; $ix < $page * 5 and array_key_exists($ix, $comics); $ix++)
 {
 echo ("<li><img src='{$comics[$ix]}' alt='comic'></li>"); # add style etc. as desired
 }
 echo ("</ul>");
 # previous/next stuff
 echo ("<ul class="comiclink">");
 if($page > 1)
 {
 echo ("<li><a href='comics.php?page=" . $page - 1 . "'>Previous page</a></li>");
 }
 echo ("<li><a href="../../subjects.php">Previous page</a></li>
 <li><a href="../../index.html">Back To Main</a></li>");
 if(count($comics) >= $page * 5)
 {
 echo ("<li><a href='comics.php?page=" . $page + 1 . "'>Next page</a></li>");
 }?> 
 </ul>
 </body>
 </html>[/code]

What I get is the following:

Subjects (Works fine)

Back To Main (Works fine)

1'>Next page (??? Not even a link)[/QUOTE]

What I want is:

Previous page

Subjects

Back To Main

Next page
[/QUOTE]

What's going wrong?

@BeachSideAug 01.2005 — #your quotes are uneven try this...

[code=php]
 echo ('<li><a href="comics.php?page=' . ($page+1) . '">Next page</a></li>');
 [/code]

Thanks, Beechside. But I'm still running into glitches. Both the "Previous" and "Next" links go to this URL: [I]/collections/subjects/beer.php?page=[/I]

@BeachSideAug 01.2005 — #Yeah you have to put the parentheses around the...

... ($page-1) and ($page+1) <-Like that ...

...otherwise it will not parse it properly

And I try to stick with the simpliest quote scheme as I can.

[code=php]
 echo ('<li><a href="beer.php?page=' . ($page - 1) . '">Previous page</a></li>');
 echo ('<li><a href="beer.php?page=' . ($page + 1) . '">Next page</a></li>'); 
 [/code]
