[RESOLVED] How can I..

How can I get this snippet to work..

if $arrHorse['horse_sex']."S" (
echo "<input type='radio' value='S' name='Sex' checked='checked'> Stallion &nbsp;&nbsp;&nbsp;";
) elseif $arrHorse['horse_sex']."M" (
echo "<input type='radio' value='M' name='Sex' checked='checked'> Mare &nbsp;&nbsp;&nbsp;";
) elseif $arrHorse['horse_sex']."G" (
echo "<input type='radio' value='G' name='Sex' checked='checked'> Gelding &nbsp;&nbsp;&nbsp;<br>";
)

I'm tryin to get it to look at that field in the datbase and see what it says and then depending on which one it is echoing a radio button checked...this is for a modifyin form so I have to echo all the radio buttons so they can have the option to change the sex.

Thanks!

Oh yeah the error its been givin me is an " unexpected T_VARIABLE (on that first line), expecting '(' " ...but i just dont know how to write an if statement I guess ...

If statements should be structure as this:

ifb[/b]
{
// All applicable code goes here
}

So, one part of your if clause would look like:

if( $arrHorse['horse_sex']."S" ){
  echo "<input type='radio' value='S' name='Sex' checked='checked'> Stallion &nbsp;&nbsp;&nbsp;";
}

You also want to make sure that you're comparing something (either to whether it's true, or comparing values) in your expression.

I checked the manual page now and went to some of the other pages to see if theyd be helpful (maybe a loop or something) but still haven't figured it out. I changed it to = between the field and string i.e.:

if ($arrHorse['horse_sex'] = "S") {
echo "<input type='radio' value='S' name='Sex' checked='checked'> Stallion &nbsp;&nbsp;&nbsp;";
} elseif ($arrHorse['horse_sex'] = "M") {
echo "<input type='radio' value='M' name='Sex' checked='checked'> Mare &nbsp;&nbsp;&nbsp;";
} elseif ($arrHorse['horse_sex'] = "G") {
echo "<input type='radio' value='G' name='Sex' checked='checked'> Gelding &nbsp;&nbsp;&nbsp;<br>";
}

But when I go to test it its displayin the first radio button checked no matter whether thats what that record should equal or not.

..and i just realized the way i have it set up right there its only going to show one of the buttons on the page...so maybe an If statement isnt the way to go because I need all three on the page no matter what I just need to somehow check and see which one the record is suppose to be and mark it as such (using one of the buttons) on the page...

What you have will only show 1 radio button. There are two things I have for you:
1.) Watch the comparison operators: = sets a value, == compares it, === strictly compares it.

The other is this: If you're just checking to see what's checked and what's not, then do this:

<?php

$sexes = array('S'=>'Stallion', 'M'=>'Mare', 'G'=>'Gelding'); // Holds all the horse sex info
$output = ''; // Empty the output var, so we start from scratch :)

foreach($sexes as $var=>$sex)
{
  $output .= '<input type="radio" name="Sex" value="'.$var.'"';
  $output .= ($var == $arrHorse['horse_sex'])?'checked="checked"':'';
  $output .= '>'.$sex.'&nbsp;&nbsp;&nbsp;&nbsp;<br>';
}

echo $output;

?>

That should give you what you want.
