Conditional HTML output not working

[wsimmonds]

Hi all,

Having a slight problem with my development machine. I've just upgraded to PHP 5.2.1 (can't remember previous version)..

I am trying to do some template-based work, and for this I like to be able to edit my HTML within Dreamweaver/visual software.

My problem is that a statement that previously worked now will not:

<? if(1 = 1) { ?>
1 is 1!
<?} else { ?>
1 is not 1!
<? } ?>

That outputs that 1 is 1, and 1 is not 1 - totally ignoring the conditional brackets. This used to work for me - I've been searching and searching and haven't yet found a configuration option. Am I missing something obvious here?

It's not urgent though, as for now I'll just put my bits of code into files and then call include() within PHP. But I would like to find out why it's suddenly stopped working..

A few things.

First, do you mean to use the assigment operator (=) in the condition of your if-statement? I generally use the comparison operator (==).

I also think that switching back and forth between HTML output mode and PHP interpreted mode reduces readability.

What does

<?
if(1 == 1)
{
   print '1 is 1!';
}
else
{
   print '1 is not 1!';
}
?>

Anyway, can you better describe what is happening on your system? I would expect the above script to always output [tt]1 is 1[/tt].

Try using == (double equal sign) instead of = (single equal sign) in your if statement. Why are you comparing 1 to 1 anyway? That will always equate to true, anyway.

Looks like sleipnir214 beat me to it here

Sorry guys that was a typo! But I had actually used the comparison operator and not assignment within the code.

That was me trying to just re-produce it.. I should have copied and pasted!

This is the strange thing, as it works on several other development/production systems - just not my own machine.

The problem is it's always outputting anything not contained within the <?/?> code area.

The real use of this is for something like:

<?
if($_GET['invalidLogin'] == 1) {
?>
HTML HERE TO SAY INVALID LOGIN
<?
}
?>

And it's always outputting! But the code below, of course, works fine and outputs nothing unless invalidLogin is indeed set to 1.

<?
if($_GET['invalidLogin'] == 1) {
echo "HTML HERE TO SAY INVALID LOGIN";
}
?>

Thanks for the respones so far I meant to add to the previous message.. I have actually been known to use = instead of == before in code.. the perils of having to also work with VB6 sometimes!

print the value of the GET superglobal elements to debug.

echo '<pre>'.print_r($_GET, true).'</pre>';

also you might take a look at sleipnir's faq on debugging techniques.
