Checkbox values in prestashop - checkbox

Question

I'm working with prestashop and try to get value from a form with checkbox using a HelperForm
SO what I had is :
$fields_form[0]['form']= [
'legend'=> [
'title'=> $this->l('Indexation')
] ,
'input'=>[
[
'type'=>'text',
'label'=> $this->l('Base(s) à indexer'),
'name'=>'options',
'size'=>20,
'required'=>true
]
],
'submit'=>[
'title' => $this->l('Save'),
'class' => 'btn btn-default pull-right'
]
];
and then
$helper = new HelperForm();
[...]
$helper->toolbar_btn = array(
'save' =>
array(
'desc' => $this->l('Save'),
'href' => AdminController::$currentIndex.'&configure='.$this->name.'&save'.$this->name.
'&token='.Tools::getAdminTokenLite('AdminModules'),
),
'back' => array(
'href' => AdminController::$currentIndex.'&token='.Tools::getAdminTokenLite('AdminModules'),
'desc' => $this->l('Back to list')
)
);
// Load current value
$helper->fields_value['options'] = Configuration::get('options');
return $helper->generateForm($fields_form);
and in my getContent I had :
$my_module_name = strval(Tools::getValue('options'));
return $my_module_name;
So until there I had no problem. I write 'test' in the text input and then 'test' is returned but I don't want a text input I want a checkbox input so I changed my form for :
$fields_form[0]['form']= [
'legend'=> [
'title'=> $this->l('Indexation')
] ,
'input'=>[
[
'type'=>'checkbox',
'label'=> $this->l('Base(s) à indexer'),
'name'=>'options',
'required'=>true,
'values'=>[
'query'=>$options,
'id'=>'id',
'name'=>'name'
]
]
],
'submit'=>[
'title' => $this->l('Save'),
'class' => 'btn btn-default pull-right'
]
];
and $options is :
$options = [
[
'id'=>1,
'name'=>'test'
],
[
'id'=>2,
'name'=>'test2'
]
];
and in my getContent(): return (Tools::getValue('options'));
But with that, nothing is displayed.
Also, if I do return sizeof(Tools::getValue('options)) It give me 1 no matter what I check with the checkbox

First you need to set the name of the field with []
$fields_form[0]['form']= [
'legend'=> [
'title'=> $this->l('Indexation')
] ,
'input'=>[
[
'type'=>'checkbox',
'label'=> $this->l('Base(s) à indexer'),
'name'=>'options[]',
'required'=>true,
'values'=>[
'query'=>$options,
'id'=>'id',
'name'=>'name'
]
]
],
'submit'=>[
'title' => $this->l('Save'),
'class' => 'btn btn-default pull-right'
]
];
Then, you options should have a value:
$options = [
[
'id'=>1,
'name'=>'test',
'val' => 1
],
[
'id'=>2,
'name'=>'test2',
'val' => 2
]
];
Then you can get the checked values with:
Tools::getValue('options')
Edit:
In 1.6 we have the admin tpl for the helper:
{foreach $input.values.query as $value}
{assign var=id_checkbox value=$input.name|cat:'_'|cat:$value[$input.values.id]}
<div class="checkbox{if isset($input.expand) && strtolower($input.expand.default) == 'show'} hidden{/if}">
{strip}
<label for="{$id_checkbox}">
<input type="checkbox" name="{$id_checkbox}" id="{$id_checkbox}" class="{if isset($input.class)}{$input.class}{/if}"{if isset($value.val)} value="{$value.val|escape:'html':'UTF-8'}"{/if}{if isset($fields_value[$id_checkbox]) && $fields_value[$id_checkbox]} checked="checked"{/if} />
{$value[$input.values.name]}
</label>
{/strip}
</div>
{/foreach}
So, to set the checkbox value to be returned we need to pass the val:
{if isset($value.val)} value="{$value.val|escape:'html':'UTF-8'}"{/if}
Also, to be checked or not when loading the page we pass the values to meet the criteria:
{if isset($fields_value[$id_checkbox]) && $fields_value[$id_checkbox]} checked="checked"{/if}
