[RESOLVED] nesting ternary operators?

Is is possible to nest ternary operators? I've tried a few different ways, but always receive a parse error. Here's my current attempt:

Thanks

Yes, but dont do it.
You are confused when writing it, what more for others when reading it?

EDIT:
you can try this instead:

<input name="font1" type="radio" value="g" <?php
if (isset($_POST['main_preview1'], $_POST['main_preview2'])
	&& $previewone[2] == "g"
	|| $loadone[2] == "g") {
	echo 'checked';
}
?> />

What does confusion have to do with making it work, albeit confusing for others?

Confusion is part of not making it work... You don't wanna debug nested ternary operators 2 months from now 🙂

Anyway, just remove the "echos" inside.

echo (isset($_POST['main_preview1']) || isset($_POST['main_preview2'])) ? (($previewone[2] == "g") ? 'checked' : '') : (($loadone[2] == "g") ? 'checked' : '');

Indented If {} else {} looks much nice :p

haha, thanks. Now I understand.

but i came up with a different solution, although it's not working all the time. maybe a fresh set of eyes would help. care to look?

the problem is that it works the first time it's called, but not the second, it reverts back to the $load value, although the $preview value is being returned on submit.

the function:
<?php
function radioChecked($preview, $letter, $load) {

if(isset($_POST['main_preview1']) || isset($_POST['main_preview2']) || isset($_POST['main_preview3']) || isset($_POST['news_preview']) && $preview == $letter){
	echo 'checked';
} else if ($load == $letter) {
	echo 'checked';
}

}

calling the function:

<input name="font1" type="radio" value="g" <?php radioChecked($previewone[2], 'g', $loadone[2]); ?>>
Goudy
<input name="font1" type="radio" value="h" <?php radioChecked($previewone[2], 'h', $loadone[2]); ?>>

...

<input name="font2" type="radio" value="g" <?php radioChecked($previewtwo[2], 'g', $loadtwo[2]); ?>>
Goudy
<input name="font2" type="radio" value="h" <?php radioChecked($previewtwo[2], 'h', $loadtwo[2]); ?>>

It is good that you state the problem, but you should also state what you are trying to do.

sorry, basically what is supposed to happen is when this page is first arrived at, the $load values are used to determined whether the g radio or h radio is checked for each category. When the user makes a change to the radio button values and hits a 'preview' (main_preview1, main_preview2, etc.) which is a submit button that submits the form to the same page, the changed valued ($preview) still remains in the form.

Also, the $load values are being pulled from a different yet identical table than the $preview values.

Thank you.

ok, i got it. there must have been a problem with my initial function conditional.
i made this change and now it works. thank you for your help.

<?php
function radioChecked($preview, $letter, $load) {

if(isset($_POST['main_preview1']) || isset($_POST['main_preview2']) || isset($_POST['main_preview3']) || isset($_POST['news_preview'])){
	if($preview == $letter){
		echo 'checked';
	}
} else if ($load == $letter) {
	echo 'checked';
}

}
