ELSE>IF TERNARY

[Omzy]

Basically I have a text input form which is built up from an array called $fields:

 

$fields=array(
  'name'=>array('Contact Name', '1', '25'),
  'company'=>array('Company Name', '1', '25'),
  'phone1'=>array('Tel Number 1', '1', '25'),
  'email'=>array('Email Address', '1', '35'),
  'url'=>array('Website URL', '0', '35'),
);

foreach($fields as $key => $value)
{
     echo '
   <b>'.$value[0].'</b>
   <input type="text" name="'.$key.'" value="', isset($_POST[$key]) ? $_POST[$key] : null ,'" size="'.$value[2].'"/>
  ';
}

 

As you can see the VALUE attribute is null upon page load or otherwise populated with its POST value if the form gets posted and has to be re-displayed.

 

This all works fine, however I need to extend the ternary statement to do an 'ELSE>IF' type operation. Basically the default value for the field 'url' needs to be 'http://' upon page load. I have tried several different ways of doing this but it just won't work for me!

 

Any ideas anyone?

I tried this:

 

value="', !isset($_POST[$key]) && $key=='url' ? 'http://' : isset($_POST[$key]) ? $_POST[$key] : null ,'"

 

But it gives me an error notice on page saying:

 

Undefined index:  url in ...

 

How is it undefinded?

Should work if you change null to ($key == 'url' ? 'http://' : null) in your original script. Nested ternary statements are not very readable though.

Cheers mate, that has worked. How come it needs to be put in brackets?

[thebadbad]

I'm not sure it's actually needed, but it makes it easier to read. And you're sure the code is interpreted the way you intended.

Well if I remove those brackets it won't work lol. So the brackets ARE needed lol.

 

Yeah it's all fine and dandy now :-)
