Hi, I'm trying to make a link like this:

<?php $previous = $number - 1; $prevTitle = XXXX; echo "<a href='loader.php?pg=$previous&subsection=1&article =$prevTitle'>

the XXXX is where i'm having trouble. I've been calling out the titles via a variable, like this:
$title1
$title2
$title3

but if I put $prevTitle= $title$previous; it gives an error. How can I get it to switch the title to match the link variably?


Thanks!!

Please paste all the code. Also what error message do you get..

Try putting the code in like this:

PHP Code:

<?php 
$previous = $number - 1;
$prevTitle = "Sometitle";
echo "<a href=\"loader.php?pg=$previous&subsection=1&article=$prevTitle\">Link</a>";

?>

Ok I have a file of variables,

in short it has:

<? php
$title1= "My first Title";
$title2= "Another Title";
$title3= "Last Title";
?>

I have a page to load the content that I want. it contains a link like this:

<?php $sub = $_GET ['sub']; $number = $_GET ['pg']; include ("$number-$sub.html"); ?>


and to change links I am using like this:
<?php $previous = $number - 1; echo "<a href='loader.php?pg=$previous&sub=1&article=$title 1'>

In the html page, I use the variable to call out the title like this:
<h1>$title1</h1>
<p> contents of page</p>


'pg' controls the main page number 'sub' controls any subsections to that page, 'article' will print out the article title at the top bar as well as on the top of the page.

So far I am doing it manually, but it would be nice if the numbers are updated automatically.

for example i think i only need a way to replace the number portion of the variable,

like $title{$previous}

but I don't know how to just change the number.

for example this:
$[title$previous] if $previous = 3

returns $[title3]

so i need it to return $title3
which should hopefully print the correct title. (the text that was assigned to $title3)

searching around I am now trying like this:

ok, so this is how far I got:

<?php $previous =3; $dollar= '$'; $g= 'title'; $preID ="$dollar$g$previous"; ?>
<?php echo $preID ;?>

but this shows $title3, it does not give me the "Title 3" from the $title3 variable.

Just put the titles in a simple array. Then you index by numbers - nice and easy.

Thanks, That worked great!

Also worth mentioning that when you do echo stuff in an array - if you want PHP to interpolate the string with array values that you can wrap them in curly braces like this: echo "Hello {$person['name']}\n"; Which can take less typing than: echo "Hello ". $person['name'] ."\n";
