This question already has an answer here:

I have this javascript function which toggles the visibility of a certain div:

function showHideDiv(id){
var obj = document.getElementById(id);
if (obj.style.display=="none"){
  obj.style.display='block';
} else if(obj.style.display=="block"){
  obj.style.display='none';
}
}

I have a dynamic div that has the id="pm_message'.$row[0].'". I want to toggle the visibility of this div via the javascript function I mentioned above.

This is my link with the onclick-function:

echo '<h1><a onclick="showHideDiv('showHideDiv("message'.$row[0].'")" class="'.$link_class.'" href="'.$profile_url.'">'.$row['title'].'</a></h1>';

It doesn't work and I get this error message:

PHP Parse error:  syntax error, unexpected '?'

Please - any help? TIA.

echo '<h1><a onclick="showHideDiv('.$row[0].')" class="'.$link_class.'" href="'.$profile_url.'">'.$row['title'].'</a></h1>';

It is already in php so you do not need to open another set of php tags.

Should be $row[0], not echo $row[0]. –  theftprevention Aug 2 '13 at 20:50
 
@theftprevention you are correct, I have made the correction –  Danny Aug 2 '13 at 20:51
 
Does not work. I updated my post. –  drpelz Aug 2 '13 at 20:53
 
@drpelz echo '<h1><a onclick="showHideDiv(\'pm_message'.$row[0].'\')" –  Danny Aug 2 '13 at 20:57

You keep changing the post, just remember if you start out using single quotes you have to escape them if you want to use them literally –  Danny Aug 2 '13 at 20:59
