Problem with CHECKED Radio Button?

[BigDC]

Hi,
I am tring to use radio buttons in a form. The thing I am trying to do is this, I have a variable that gets its data from a database. The variable's name is $layout. I am trying to have the value that is stored in the database be used to determine which radio button is checked, but it is not working.

I have checked and made sure there is a value being transmitted to the $layout variable, and there is. Everything else is working but what I want, how can I fix it?

I need to keep the code in my echo statement.

Here is the code I am trying to use.....

echo'
...More html form code up here...

<input name="layout" type="radio" '.$layout=='1' ? echo 'CHECKED' .'value="1" />
<input name="layout" type="radio" '.$layout=='2' ? echo 'CHECKED' .'value="2" />
<input name="layout" type="radio" '.$layout=='3' ? echo 'CHECKED' .'value="3" />
<input name="layout" type="radio" '.$layout=='4' ? echo 'CHECKED' .'value="4" />

...More html form code down here...'; 

Please help?

Thanks.

To help debug your code,

1) open the php file containing the form in your browser

2) right click the page and select 'view source'

3) this will be the code generated by your echo statement.

4) check if the php generated html code is correct for the radio buttons.

5) make sure the value of $layout is a valid value and within the correct range of values.

It looks like you might be using an xHTML doctype based on your closing of the input tags. If that is the case you should be using the checked attribute as in:

<input type="radio" checked="checked" name="layout" value="yourValue" />

What I am trying to get at is this....


If the value of what is in the variable of $layout is 1, then the first radio button is the one that should be showed as being checked.

If the value of what is in the variable of $layout is 2, then the second radio button is the one that should be showed as being checked.

If the value of what is in the variable of $layout is 3, then the third radio button is the one that should be showed as being checked.

If the value of what is in the variable of $layout is 4, then the fourth radio button is the one that should be showed as being checked.

That is what I am trying to do with this code below, but it is not working. I get syntax error, unexpected T_ECHO.

Obviously my php code BELOW is incorrect somehow and I do not know what I need to change to fix it?

I get syntax error, unexpected T_ECHO.

Why didn't you post your error message in your first post.

If you don't post the error messages, let alone all your code then I can't help anymore.

I skipped school the day they taught mind reading

Just use some basic Debugging 101 to find the source of the t_echo error.

So maybe you need to use a full if statement rather than a ternary operator?

if(statement evaluates to true){ do this }
