how to add zend form elements to the form in php?

Question

i have a foreach loop in my zend form, in this case the $this->args[1]has a count of 5 :

foreach ($this->args[1] as $val)
    {

        $submitImage = new Zend_Form_Element_Image('submit_image');
        $checkBox = new Zend_Form_Element_Checkbox('id_checkbox');

        $this->addElement( $submitImage ->setImage($val->full_path) );
        $this->addElement( $checkBox ->setValue($val->id) );
    }

the problem i encounter is that the $submitImage and $checkBox get overwritten and i only get one element of each, the last one.

any ideas how to make them all show up?

thanks

i've also tried:

$i=0;
foreach ($this->args[1] as $val)
    {

        $submitImage = 'submitImage'.$i;
            $checkBox = 'checkBox'.$i;

        $submitImage = new Zend_Form_Element_Image('submit_image');
        $checkBox = new Zend_Form_Element_Checkbox('id_checkbox');

        $this->addElement( $submitImage ->setImage($val->full_path) );
        $this->addElement( $checkBox ->setValue($val->id) );
    $i++;
    }

but it doesn't work

You will have to give each element a unique name, or use subforms. See stackoverflow.com/questions/405897/… — drew010

your really close, only need minor fixes. Anything to make the name of the element unique.

foreach ($this->args[1] as $val)
    {

        $submitImage = new Zend_Form_Element_Image('submit_image'. $val->id);
        $checkBox = new Zend_Form_Element_Checkbox('id_checkbox' . $val->id);

        $this->addElement( $submitImage ->setImage($val->full_path) );
        $this->addElement( $checkBox ->setValue($val->id) );
    }

or if you like

$i=0;
foreach ($this->args[1] as $val)
    {

        $image = 'submitImage'.$i;
            $box = 'checkBox'.$i;

        $submitImage = new Zend_Form_Element_Image($image);
        $checkBox = new Zend_Form_Element_Checkbox($box);

        $this->addElement( $submitImage ->setImage($val->full_path) );
        $this->addElement( $checkBox ->setValue($val->id) );
    $i++;
    }

Liyali has the right of it I'm just more verbose :)

[EDIT] corrected variable collision in second loop.

the first foreach worked. the second one didn't for some reason, just in case someone else reads this answer. Lots of thanks

Your element names must be different.

 $submitImage = new Zend_Form_Element_Image($submitImage);
 $checkBox = new Zend_Form_Element_Checkbox($checkBox);
