validation prep_for_form array data bug - El Forum - 02-20-2008
[eluser]Wilker[/eluser]
When you post some array data in post (like multiple checkbox) script generate warning because the function tries use str_replace in one array. the real bug is only in one line that is not where he was to be, this is the actually prep_for_form function:
Code:
function prep_for_form($data = '')
{
if (is_array($data))
{
foreach ($data as $key => $val)
{
$data[$key] = $this->prep_for_form($val);
}
}
if ($this->_safe_form_data == FALSE OR $data == '')
{
return $data;
}
return str_replace(array("'", '"', '<', '>'), array("'", """, '<', '>'), stripslashes($data));
}for fix this problem, just add a line after foreach inside is_array if, like this:
Code:
function prep_for_form($data = '')
{
if (is_array($data))
{
foreach ($data as $key => $val)
{
$data[$key] = $this->prep_for_form($val);
}
return $data; //line added
}
if ($this->_safe_form_data == FALSE OR $data == '')
{
return $data;
}
return str_replace(array("'", '"', '<', '>'), array("'", """, '<', '>'), stripslashes($data));
}this makes the function returns array data prepared, and the script don't reach str_replace this way.
