 Posted: Tue May 13, 2008 10:41 pm Post subject: Solved: QuickForm removeElement method on group item |
 |
|
I am very new to object oriented programming, and am trying to figure out how to remove elements in a group, or actually the whole group. For example:
$buttons[] = &HTML_QuickForm::createElement('reset', 'submit_reset', 'Reset');
$buttons[] = &HTML_QuickForm::createElement('submit', 'submit_request', 'Submit Request');
$form->addGroup($buttons, null, null, ' ');
and then :
$form->removeElement('submit_reset');
does not work, as I would expect, because it is in an array, but how do I do it?
thanks in advance

removeElement() indeed doesn't help you for groups. At first, you'll need a reference to the group element. This can be done either by "remembering" the object, e.g:
| Code: |
$group = $form->addGroup($buttons, null, null, ' ');
|
or by a getElement() call, e.g.:
| Code: |
$group = $form->getElement('nameOfYourGroup'); // name isn't assigned in your example
|
$group has now a getElements() method that returns an array of the group elements:
| Code: |
$elements = $group->getElements();
|
Removing the element from the group is now only a usual array operation.
(If you're using PHP 4, you'll need to add some "&".) |

Thanks for the reply, I tried the following, and the buttons still show up. There must be something, I don't get. I am using php 5, by the way.
| Code: | <?php
// Include HTML_QuickForm
require_once 'HTML/QuickForm.php';
// Instantiate our form, called 'Create'
$form = new HTML_QuickForm('Create', 'POST');
// Don't forget the Submit button!
$buttons[] = &HTML_QuickForm::createElement('reset', 'submit_reset', 'Reset');
$buttons[] = &HTML_QuickForm::createElement('submit', 'submit_request', 'Submit Request');
$group = $form->addGroup($buttons, null, null, ' ');
$elements = $group->getElements();
// Remove unnecessary elements and show result
print_r ($elements);
unset($elements[0]);
unset($elements[1]);
print_r ($elements);
// Process Form
if ($form->validate())
{
// Form Validates
// Handle Form here
$form->freeze();
$formsource = $form->toHtml();
}
else
{
// Form has not yet been submitted, or is invalid, show form
$formsource = $form->toHtml();
}
echo $formsource;
?> |
I realize this is a dumb example, but I wanted to simplify it to post.
thanks,

Please use the [code]...[/code] environment next time, this makes the code more readable.
I made a mistake in my explanation: The getElements() call needs the &. This ensures a reference, and your example works then as expected.
BTW, the example isn't dumb. Such short examples without any unneeded things are very welcome. |
