form.elements

[novice2004]

Help please.
Does anybody know if it is possible to send a string from php to JavaScript and then to concatenate it into object
because it does not work for me.
Gives me "Error on Page".
Thank you.



<FORM NAME="form" ID="form" ACTION="Layout.php" METHOD="post"

<input type="checkbox" name="title[]" value="1" />
<input type="checkbox" name="title[]" value="2" />
<input type="checkbox" name="title[]" value="3" />

$v1 = "form";

$v2 = "elements[\"title[]\"]";



print("<a href=\"javascript:document.form.submit()\" onClick=\"return validate(" . $v1 . "," . $v2 . ")\" >GO</a>");




function validate(v1,v2)
{


field = eval(v1 + "." + v2);

return ( validateCheckbox(field) );
}




function validateCheckbox(field)
{
for (i = 0; i < field.length; i++)
{ if(field.checked == true) return true; }

alert("Please select at least one checkbox.");
return false;
}

1) Never use "form" as a form name. Instead, use something like "form1".

2) You're most likely getting into a double-quote induced hell. Try something like this:

print '<a href="document.form.submit();" onclick="return validate(\'' . $v1 . '\',\'' . $v2 . '\');">GO</a>';

Side note: rather than eval() stuff use something like this:

$v2 = "title[]";
...
function validate(v1,v2)
{   field = document.forms[v1].elements[v2];
    return ( validateCheckbox(field) );
}
