If a field has a default value, it cannot be empty on insert.

Still an issue

I believe this is because _field_invoke_default() assumes that if a field is empty, the default needs to be added. This is great in the case of a pro-grammatically created node. However, if someone is adding a new node through the user interface, they will not be allowed to clear the default value for any field - even if it is not required.

hello ,

i have a form with 2 textfields within a fieldset. Both have some assigned #default_value. when i test the form, the first textfield would print out the content entered in that textfield correctly. However the second textfield would always print out the #default_value. No matter what i type in the form the valus is always the #default_value. I have no idea what is causing this. The two textfields are pretty much identical in all their attributes and location in the form.

any ideas would be great.. i wasted many hours on this issue...

thanks,

here is the code:
// Form Fieldset
$form['myFieldset'] = array(
'#title' => t('Pricelists Config Options'),
'#type' => 'fieldset',
'#prefix' => '

',
'#collapsible' => TRUE,
'#collapsed' => TRUE,
);

//TextField 1
$form['myFieldset']['TextField_1'] = array(
'#title' => t('TextField 1),
'#type' => 'textfield',
'#required' => FALSE,
'#size' => 5,
'#maxlength' => 256,
'#weight' => $weight++,
'#default_value' => t('1.00'),
);

//TextField 2
$form['myFieldset']['TextField 2'] = array(
'#title' => t('TextField 2'),
'#type' => 'textfield',
'#required' => FALSE,
'#size' => 5,
'#maxlength' => 256,
'#weight' => $weight++,
'#default_value' => t('TextField 2'),
);

While you may have a support question, please don't override a core field issue.

After many attempts i figured out what was causing the problem.

if you look at my naming, i had an underscore in the 1st, and a space in the 2nd.
Changing:
$form['myFieldset']['TextField 2'] to $form['myFieldset']['TextField_2']

Moreover, i found out that periods in a name do not work either so ['U.S. drupal'] and ['U.S._drupal'] would fail while ['US_drupal'] would not.

i am not sure what you want to do with this or where the fix should be, but it seems that it is an error for me that needs fixing...

thanks,

Unfortunately, there is no way to know if that field was supposed to retain its value, or if it was truly representing the default. If the behavior were to change, it would be confusing and data-destructive.

This is an actual bug, dupe of #1253820: It's impossible to submit no value for a field that has a default value. That other thread is newer, but gathered more insight.
