Single html Form With Multiple Submit Buttons

Not exactly sure what you are trying to show here Bill!

But your Block [8500] won't display any values for the post variables named preview or create because they do not exist in the form!

Code:

// +---------+---------+---------+---------+---------+---------+
// [8500] these two lines do nothing
// +---------+---------+---------+---------+---------+---------+
echo '<br>[8501] do nothing ' . $this->input->post('preview'); // This will return the Boolean FALSE
echo '<br>[8502] do nothing ' . $this->input->post('create');   // This will return the Boolean FALSE

The following is Soley For Debug Purposes to see what is happening!!!

Code:

// +---------+---------+---------+---------+---------+---------+
// [8510] these two lines do nothing as the values do not exist
// +---------+---------+---------+---------+---------+---------+
echo '<br>[8511] I do something but  ';
echo ($this->input->post('preview')===false)?'I Do Not Exist':'I do Exist';
echo '<br>[8512] I do something but ';
echo ($this->input->post('create')===false)?'I Do Not Exist':'I do Exist';
// +---------+---------+---------+---------+---------+---------+
// [8520] Var_dump the Post Values - Both will Return False
// +---------+---------+---------+---------+---------+---------+
echo '<br>[8521] var_dump of preview';
var_dump($this->input->post('preview'));
echo '<br>[8522] var_dump of create';
var_dump ($this->input->post('create'));

Interesting Note: When echoing a string with a concatenated ternary like...

Code:

echo '<br>[8511] I do something but  '. ($this->input->post('preview')===false)?'I Do Not Exist':'I do Exist'

The first string part ie

Code:

'<br>[8511] do something but '.

- does not display. Only the result of the ternary displays. So the fix is to put them as separate echo calls!
