insert html elements before a field

[fgazza]

Hello everyone!
I would like to insert a custom text before a field. The text should be formatted in html and precede the field label.
I think the solution is to use $html in the hook file's tablename_dv () function but I have no idea how to use it. For example, I would like to display the image mysite / image.jpg before the field label and a paragraph below the image.

Could anyone please tell me how to use the $html parameter?

THANKS!

I might be wrong because I never used html in that function but your can try echo '<p> html code</p>'; or close and re-open the php syntax like this:

Code: Select all

?>

<p>hmtl code</p>

<?php

hope it helps, cheers!

Hi,

appending custom html to the bottom of DV or prepending html to the top is not hard by just modifying the given $html variable. But here, the challenge is to place the custom html above the field.

If this is a normal field (and not a lazy loaded lookup) you can do it this way:

file: hooks/TABLENAME.php

Code: Select all

function TABLENAME_dv($selectedID, $memberInfo, &$html, &$args)
{
	$fieldname = "resource_type"; // TODO: change $fieldname
	
	$html .= '<p id="my_custom_paragraph" class="well">my <i>custom paragraph</i> with <b>bold</b> text</p>';
	$html .= '<script>$j("#my_custom_paragraph").prependTo($j("#' . $fieldname . '").closest(".form-group"))</script>';
	
	// ...
}

Result

Inserted above field named "resource_type".

Many thanks!

with your suggestion I prepared the form correctly (i set my code into div tag and not into p tag because i have several paagraph and an image) but unfortunately if I view the form itself with the "print" option (print view), my custom html code is displayed below the form fields.

I would be grateful for your help.

Thank you but as I renew many times my app generating new files by appgini tool i prefer a solution that affect only the hook file.
