Form Checkbox

[Raskolnikov]

I have a checkbox element in a form i have created which can have multiple values....making it an array.

I am confused as to #1 how to echo its values, and #2 how to save the arrays value into a database.

It would be nice to convert the array into a string and save it that way.

WHat might make this a little more frustrating for some of you, I am useing the Pear::quickform class to generate the form. I do like useing the quickform class, however, it doesn't offer very good documentation for those of us that don't read directions very well, and don't have a solid knowledge of PHP/MySql.

here is the checkbox code i have to this point:

$checkbox[] = &HTML_QuickForm::createElement('checkbox', 'QB', null, 'QB');
        $checkbox[] = &HTML_QuickForm::createElement('checkbox', 'RB', null, 'RB');
        $checkbox[] = &HTML_QuickForm::createElement('checkbox', 'FB', null, 'FB');
        $checkbox[] = &HTML_QuickForm::createElement('checkbox', 'TE', null, 'TE');
        $checkbox[] = &HTML_QuickForm::createElement('checkbox', 'OG', null, 'OG');
        $checkbox[] = &HTML_QuickForm::createElement('checkbox', 'OT', null, 'OT');
        $checkbox[] = &HTML_QuickForm::createElement('checkbox', 'C', null, 'C');
        $checkbox[] = &HTML_QuickForm::createElement('checkbox', 'TE', null, 'TE');
        $checkbox[] = &HTML_QuickForm::createElement('checkbox', 'WR', null, 'WR');
        $checkbox[] = &HTML_QuickForm::createElement('checkbox', 'S', null, 'S');
        $checkbox[] = &HTML_QuickForm::createElement('checkbox', 'CB', null, 'CB');
        $checkbox[] = &HTML_QuickForm::createElement('checkbox', 'DE', null, 'DE');
        $checkbox[] = &HTML_QuickForm::createElement('checkbox', 'DT', null, 'DT');
        $checkbox[] = &HTML_QuickForm::createElement('checkbox', 'MLB', null, 'MLB');
        $checkbox[] = &HTML_QuickForm::createElement('checkbox', 'OLB', null, 'OLB');
        $checkbox[] = &HTML_QuickForm::createElement('checkbox', 'P', null, 'P');
        $checkbox[] = &HTML_QuickForm::createElement('checkbox', 'K', null, 'K');
        $checkbox[] = &HTML_QuickForm::createElement('checkbox', 'Return Man', null, 'Return Man');
        $checkbox[] = &HTML_QuickForm::createElement('checkbox', 'KOR Team', null, 'KOR Team');
        $checkbox[] = &HTML_QuickForm::createElement('checkbox', 'KO Team', null, 'KO Team');
        $checkbox[] = &HTML_QuickForm::createElement('checkbox', 'Punt Team', null, 'Punt Team');
        $checkbox[] = &HTML_QuickForm::createElement('checkbox', 'Punt Ret Team', null, 'Punt Ret Team');
        $checkbox[] = &HTML_QuickForm::createElement('checkbox', 'Field Goal/Block unit', null, 'Field Goal/Block unit');
        $form->addGroup($checkbox, 'ichkPos', 'Positions Played:', array('&nbsp;','&nbsp;','&nbsp;', '<br />'));
        $form->addGroupRule('ichkPos', 'Please check at least one box', null, 1); 

I have tried a coule of things.

this:

$pos1 = $form->getSubmitValue('ichkPos');
                
                echo ($pos1); 

returns "array"

this:

$pos1 = $form->getSubmitValue('ichkPos');
                
                $text=implode($pos1);
                echo ($text); 

returns 1's depending on how many boxes I have checked. for instance, If i select 3 of the boxes, the output is "111". 6 selected kgets me "111111"

what do you think?

w/o being familiar with pear::quickform i'll hazard a guess that your doing it wrong.

First I think, from seeing your results of trying to output the array I'd say that your creating checkboxes that are all named differently, meaning that what you really want is this:

$checkbox[] = &HTML_QuickForm::createElement('checkbox', 'ichkPos', null, 'TE'); 
$checkbox[] = &HTML_QuickForm::createElement('checkbox', 'ichkPos', null, 'OG'); 

Not what you currently have.
To see the contents then try this temporarily:

$pos1 = $form->getSubmitValue('ichkPos'); 
print_r($pos1); 

normally to just print the contents of an array you would do:

foreach ($pos1 as $value)
{
print $value;
} 

HTH for now

Additionally I dont think your using the addGroup() right. Probably just take it out for now.

I Used what you told me:

<?php
// Include QuickForm class
require_once ("HTML/QuickForm.php");
        
        // Instantiate the QuickForm class
        $form = new HTML_QuickForm('Selecttest','POST','checkTest.php');

        // Add a header to the form
        $form->addHeader('Header Title Here.');
        
        $checkbox[] = &HTML_QuickForm::createElement('checkbox', 'ichkPos', null, 'QB');
        $checkbox[] = &HTML_QuickForm::createElement('checkbox', 'ichkPos', null, 'RB');
        $checkbox[] = &HTML_QuickForm::createElement('checkbox', 'ichkPos', null, 'LB');
        $checkbox[] = &HTML_QuickForm::createElement('checkbox', 'ichkPos', null, 'FB');
        $form->addGroup($checkbox, 'ichkPos', 'Positions Played:');
        
        // Add a submit button
        $form->addElement('submit','submit','Accept Changes','class="createAccount"');
          if ( $form->validate() ) {
                $pos1 = $form->getSubmitValue('ichkPos'); 
                print_r($pos1);                            
        } else {
            // If not submitted, display the form
            $form->display();
        }
 
 
?>

and this is what it returned:

Array ( [ichkPos] => 1 )

i have no idea what that means. Can you help?

Raskolnikov,

I am having the same problem as you did. Did you find a solution and if so could you let me know what you did?

Thanks

I always set the values up in their own array --

$cvAge[] = 'Pre-K';
$cvAge[] = 'Elementary';
$cvAge[] = 'Middle School';
$cvAge[] = 'High School';

And then use a function to build the checkbox elements --

function MakeCheckGroup(&$form, $name, $label, $values)
{
	foreach ($values as $i => $value)
	{
	        $group[] = &$form->createElement('checkbox', $i, null, $value);
	}
        $form->addGroup($group, $name, $label, '<br>');
}

Then I call it when I build the form like so --

MakeCheckGroup($form, 'chkTargetAge', 'Target Age', $cvAge);

If the user checks anything off, an array will come through $_POST or $_GET that looks like --

chkTarget[2] = 1
chkTarget[3] = 1
etc...

If you wanted to build a string, you could do something like this --

foreach ($_POST['chkTargetAge'] as $i => $check)
{
	$vals[] = $cvAge[$i];
}

join(',', $vals);

Let me know if that didn't make sense.
