Using variables in hrefs

[Michelle]

Hi all,

I was wondering if I can incorporate a variable (actually a calculation)
in an href statement such as:

print "<a href='calendar. php?month = $month-1'>go back a month</a>

I wouldn't think that this is the correct syntax, but the basic idea is
there.

TIA

Miki

You can include anything as long as you urlencode it.

Try this:

print "<a href='calendar. php?month={$mon th-1}'>go back a month</a>";

.... or:

print "<a href='calendar. php?month=" . $month - 1 . "'>go back a month</a>";

In a double-quote delimited string you have variable parsing, not
expression parsing. You'll have to use the dot operator to concatenate
strings:

"blah" . funct($foo) . "bla"

Formatted String Approach

echo sprintf('<a href="calendar. php?month=%s">G o back a month</a>' ,
$month - 1);

Template Approach

$url = '<a href="calendar. php?month=[month]">Go back a month</a>';
echo str_replace('[month]' , $month - 1 , $url);

Precalculated Approach

$prevmonth = $month - 1;
echo "<a href='calendar. php?month=$prev month'>go back a month</a>";
Take your pick

Why don't write just '<a href="calendar. php?month='.$mo nth.'">go back a
month</a>

Because $month contains the number of the current month, and he wants the
link to go to the previous month.

And the manual is there to tell you what the right syntax is.

Btw, if $current_month == 1, then $previous_month = 12
and if $current_month = 12, then $next_month = 1

the easiest, but not the fastest, IMHO way is
if(date('m',tim e())!==1) $prev_month=dat e('m', time())-1;
else $prev_month=12;
