Dynamic image displays depending on yes / no value

I´d like to have a image showing, depending on a specific value (y/n)

..sorry need some help.

I can´t get it workin.....

<img <?php $status="n";

if ($status == "y") {

echo 'src="stecker_on.png" alt="yes"';

} else {

echo 'src="stecker_off.png" alt="no"';

} ?> height="71" width="101" />

The image ist not showing... ideas ?

All I get ist some text showing:

height="71" width="101" />

MANY THANKS !!!!

In the code that you show above, $status is explicitly set to "n" at the beginning (<?php $status="n";), so the conditional will always evaluate to the 'else' part - is that what you want?

All I get ist some text showing:
height="71" width="101" />

That's what you see on the page - those words in readable text? Try this -

<img src="stecker_<?php $status="n"; echo ($status == "y")?'on':'off'; ?>.png" alt="<?php echo $status=="y"?'yes':'no'; ?>" height="71" width="101" />

nooob....

sorry, it´s not working.

i´ve tried it in different combinations....

result showing up:

Parse error: syntax error, unexpected '<'

That error could only mean that you didn't implement my suggestion correctly, or that there is a pre-existing error on your page. The code I gave you is correct.

Many thnaks, now it´s working fine for me.

(the file extension writen with Dreamweaver was set to html)

Presumably you mean this -

http://mediaconsults.de/1test/steckertest.php

And it's not clear what that is going to show me. Looking at the code on the page -

<html>

<head>

<title>Unbenanntes Dokument</title>

<!--

function MM_reloadPage(init) { //reloads the window if Nav4 resized

if (init==true) with (navigator) {if ((appName=="Netscape")&&(parseInt(appVersion)==4)) {

document.MM_pgW=innerWidth; document.MM_pgH=innerHeight; onresize=MM_reloadPage; }}

else if (innerWidth!=document.MM_pgW || innerHeight!=document.MM_pgH) location.reload();

}

MM_reloadPage(true);

//-->

</script>

</head>

</body>

</html>

I would advise you the following:

1. Put a valid and complete doctype on that page!

2. Get rid of the resize if NN4 javascript - it hasn't been needed for nearly a decade.

3. Fix your image code (note the missing space after "no"!

4. 1290px is way too wide unless you want lots of people scrolling right to see things.

ok, i´ll give it a try this evening.

(I set the $status for testing to n - later i´ll read out the status of my light swithes in my home automation system... depending on the status I´ll show an image with lights on ...)
