so I have this php code

$listing .= "<button onclick='updateValue(".$id.", ".$key.")'>change value</button>";

$id is an integer and works just fine, key is a reference from a for loop and the value translate well in the html code however the key value table is recognised as a variable instead of a string.

HTML: onclick="updateValue(3, table)"

I have tried evey trick I know (creating new variable with quotes, adding single quotes in the onclick and (string)$key ) to convert it as a string but nothing is working so far. any idea please ? is it even possible ?

You need to add quotes to tell javascript that it's a string. Since you're inside an echo you'll need to escape the quotes:

$listing .= "<button onclick='updateValue(".$id.", \"".$key."\")'>change value</button>";

i think he's saying the key is a variabel
He can also do ' ". $key ." ' where the single quotes makes it a JS string and the double quotes escape it from PHP.
@LeviSchmidt No, the single quotes are already used to wrap the onclick action.
@Iwrestledabearonce. I read it as "if $key has the value table, javascript sees a variable table instead of the string 'table'"
thats it, thanks a bunch, I learned something ! will accept asap

$listing .= "<button onclick='updateValue(".$id.", \"".$key."\")'>change value</button>";
