Get the form slug in the hf_form_html filter hook

Ok, my code for getting the current form slug can be simplified, but the question remains: is there a plugin specific or simpler way to do this?

add_filter( 'hf_form_html', function( $html ) {
    $dom = new DOMDocument();
    $dom->loadHTML( $html );
    $slug = $dom->getElementsByTagName( 'form' )->
        item(0)->getAttribute( 'data-slug' );

    if( $slug == 'my-form-slug' ) {
        ...
    }
}

Hi,

The form should be in the second argument, so I think it should be:

add_filter( ‘hf_form_html’, function( $html, $form ) {
if($form->slug == ‘…’)
{
…
}
}

I’m sorry I did not have time to test it so let me know if it doesn’t work!

Hope that helps. If you have any questions, please let me know!

@lapzor,

No succes! I suppose that in the case of hf_form_html filter hook this doesn’t work, it accept only one argument – $html, that contains the form itself.

Yeah you’re right….

I found that the slug is actually in the html, so you could use str_pos:

add_filter( ‘hf_form_html’, function( $markup ) {
if(strpos($markup, ‘data-slug=”my-slug”‘)) {
$markup .= ‘My Slug is found’;
} else $markup .= ‘My slug wasn’t found’;
return $markup;
});

Just tested this on my own setup and it worked for me.

Hope that helps. If you have any questions, please let me know!

@lapzor,

Very good! Thank you very much!

add_filter( ‘hf_form_html’, function( $html ) {
$doc = new DOMDocument( ‘1.0’, ‘UTF-8’ );
$doc->loadHTML( $html );
$attr = array();
$form = $doc->getElementsByTagName( ‘form’ )->item(0);
foreach( $form->attributes as $attribName => $attribNodeVal ) {
$attr[$attribName] = utf8_decode( $form->getAttribute( $attribName ) );
}

if( $attr[‘data-slug’] == ‘my-form-slug’ ) {
…
}
}
