XOOPS FAQ - Hacks and modifying code - How to make xoopsformhidden xhtml-valid?

Remark: I don't know if this is really a FAQ. But this one disturbed me when making my page xhtml-valid. There are two possible solutions. 1. make a tray with another formelement inside a module or 2. make the change systemwide which is much easier for the non-php-techie. Look for function render in include/xoopsform/xoopsformhidden.php and the line which reads:


return "<input type='hidden' name='".$this->getName()."' id='".$this->getName()."' value='".$this->getValue()."' />";

Problem with this code is, that the input-field for hidden will inserted between the tr-lines of the table which is not xhtml-valid. Just change the above line to:


return "<tr style='display:none;'><td colspan='2' style='display:none;'><input type='hidden' name='".$this->getName()."' id='".$this->getName()."' value='".$this->getValue()."' /></td></tr>";

What I did was just inserting another table-row. To prevent the new table-row from being displayed I used the style display:none. That is all!

I had the same validation problem.

I made this update un the render function but these function seems to be used in (a least one) other places.

With this modification, when you want to update a module (after a template modification), the update and cancel buttons are placed just under the header...

Another solution

Hi all, I've finally found another solution (thanks to an xoops-france member)...

There is no need modifying formhidden.

First, just modify the file class/themeform.php and replace


} else {

    $ret .= $ele->render()."n";

}


} else {

    $hiddens .= $ele->render()."n";

}

and the replace just after this line


$ret .= "</table></form>n";


$ret .= "</table>".$hiddens."</form>n";

The function render() will now produce an html valid form.

For the contact module, there is another modification. Indeed, there is no need for a simple form to use a template, XOOPS can do it perfectly well. So in the file modules/contact/index.php comment the above two lines


...

$xoopsOption['template_main'] = 'contact_contactusform.html';

...

$contact_form->assign($xoopsTpl);

and then add the following line to the modules/contact/contactform.php


$contact_form->display();

after the last $contact_form->addElement

That's done, you will now have a valid html contact form.
