Well, I now have modified the script so the end and startpages are there
too. Also the script reads the captions and the variables from
includefiles. But I want to simplify my site even more:
At the moment, the directory structure is as follows:
index.html
photo/rroma/index.php
photo/rroma/captions.txt
photo/rroma/vars.inc
photo/travel/spain/index.php
photo/travel/spain/captions.txt
photo/travel/spain/vars.inc
links in index.html point to the index.php files. But the index.php
files are exactly the same, as they read vars and captions from textfiles.
What I want is an index.html with links that point to a single index.php
file. The links in the html file should contain querystrings that will
be passed to the phpscript so that the script knows from which directory
to get the captions and vars. so the structure will look like this:
index.html
index.php
photo/rroma/captions.txt
photo/rroma/vars.inc
photo/travel/spain/captions.txt
photo/travel/spain/vars.inc
How do I do that??
This is the script with include files up to now:
## index.php
<?php
// Read config from file
include("vars.inc");
// Create path structure
$dirPath=str_repeat("../",$dirLevel);
// Get the page request from $_GET
if(isset($_GET['page'])&&is_numeric($_GET['page'])){
$_GP=$_GET['page']>0?$_GET['page']:1;
}else{
$_GP=1;
}
// Assign next, previous and current variables
if($_GP>1&&$_GP<$pages){
list($p,$n,$c)=array($_GP-1,$_GP+1,$_GP);
}elseif($_GP==1){
list($p,$n,$c)=array($pages,2,1);
}elseif($_GP==$pages){
list($p,$n,$c)=array($_GP-1,1,$_GP);
}
// Prefix variables with "0" if value is less than 10
$preName=$p<10?"0{$p}":$p;
$curName=$c<10?"0{$c}":$c;
$nxtName=$n<10?"0{$n}":$n;
// First and last page must point to $startPage
if($startPage!==0&$c==$pages){
$rootDir = dirname($_SERVER['PHP_SELF']);
$next="{$rootDir}/${dirPath}${startPage}";
}else{
$next="{$_SERVER['PHP_SELF']}?page={$n}";
}
if($startPage!==0&$c==1){
$rootDir = dirname($_SERVER['PHP_SELF']);
$prev="{$rootDir}/${dirPath}${startPage}";
}else{
$prev="{$_SERVER['PHP_SELF']}?page={$p}";
}
// Check for the the source image...
if(!is_file($curImg="{$jpgDir}/images/{$curName}.jpg")){
trigger_error("Missing image file $curImg",E_USER_ERROR);
}
// Get image properties
list($x,$y,$type,$attr)=getimagesize($curImg);
// Get the photo caption for this image
$caption=$captions[$c-1];
// Send template to browser
