Repopulating checkbox using CI syntax: confused.

[eluser]moonbeetle[/eluser]
Hi, from what I see in the user guide, set_checkbox() isn't meant to be used with the form_checkbox() method.
Looks like set_checkbox() can only be used if you literally follow the example in the user guide, thus adding checkboxes in plain old HTML style, not CI generated style.

Found a small error in your code, to output a checkbox CI style, use form_checkbox() instead of form_input.
Also, for a checkbox, the data array can have a key called 'checked' which you set to have a value of TRUE/FALSE. This can be done hardcoded or dynamically (by matching the value of the checkbox).

Code:

// CI generated checkbox, checked='checked' by default
$data = array(
    'name'        => 'bestemming[]',
    'id'          => 'industrie',
    'value'       => 'industrie',
    'checked'      => TRUE,
    'type'        => 'checkbox'
);
echo form_checkbox($data);
echo form_label('Industrie', 'industrie');



// CI generated checkbox, checked status determined by value
$checkval = "industrie2"; // quick test
// $checkval should be provided by the controller as part of data passed to the view

$data = array(
    'name'        => 'bestemming[]',
    'id'          => 'industrie2',
    'value'       => 'industrie2',
    'checked'      => (isset($checkval) && $checkval == "industrie2")?TRUE:FALSE,
    'type'        => 'checkbox'
);
echo form_checkbox($data);
echo form_label('Industrie 2', 'industrie2');

About your question, "Repopulating", suggests you want to display the form again, after submit. Worth checking CI's validation class in combination with the form helper and validating arrays.
