Allow all attributes in $allowedposttags tags

Question

I would like to use $allowedposttags to allow extra HTML tags during entry submission. Can I allow all attributes for a specific tag using $allowedposttags?

For example, the code below will allow iFrame tags and the src, height, and width attributes in the iFrame tags:

$allowedposttags['iframe'] = array(
    'src' => array(),
    'height' => array(),
    'width' => array()
);

How can I allow all attributes in this example, not just src, height, and width?

Answer 1

I'm pretty sure you have to explicitly name all allowed attributes - just use:

$allowedposttags['iframe'] = array (
    'align'       => true,
    'frameborder' => true,
    'height'      => true,
    'width'       => true,
    'sandbox'     => true,
    'seamless'    => true,
    'scrolling'   => true,
    'srcdoc'      => true,
    'src'         => true,
    'class'       => true,
    'id'          => true,
    'style'       => true,
    'border'      => true,
);
