This hook can be used to add HTML within input tags in a field. It is especially helpful for adding HTML5 placeholder text, required attributes, and formatting field input.
Usage
add_action('frm_field_input_html', 'add_input_html');
function add_input_html($field)
Parameters
- $field (array)
Examples
Insert required and placeholder
Use this code to add HTML directly in your input field. This example adds HTML5 placeholder text and required attributes. This can also be done in your customizable HTML by changing [input] to [input required="required"] or [input placeholder="2"]. Any other HTML can be added in this code or to your customizable HTML as well.
add_action('frm_field_input_html', 'add_input_html');
function add_input_html($field, $echo=true){
$html = '';
if($field['id'] == 25){ //change 25 to the ID of your field
$html = ' required="required"';
}
if($field['type'] == 'number'){
$html = ' placeholder="2"';
}
if($echo)
echo $html;
return $html;
}Add the field name as input title
If you would like your input fields to show the field title on hover, you can add it in your customizable HTML with [input title="The field name"]. If you would like this to be on a larger number of fields, php may be easier.
add_action('frm_field_input_html', 'add_input_title');
function add_input_title( $field, $echo = true ) {
$html = '';
if($field['type'] == 'text'){
$html = ' title="'. esc_attr( $field['name'] ) .'"';
}
if($echo){
echo $html;
}
return $html;
}
