Actually, there were 2 misstakes:
<?php
function get_InfoContent($instance_id, $form_id, $InfoKey)
{
$query = mysql_query("
SELECT instance_id, form_id, InfoContent
FROM forms_single_info
WHERE instance_id=".$instance_id." AND form_id=".$form_id." AND
InfoKey='".$InfoKey."'
");
if (mysql_num_rows($query) > 0)
{
$result = mysql_fetch_assoc($query);
$InfoContent = $result['InfoContent'];
return $InfoContent;
}
else
{
$InfoContent = get_InfoContent(0, 0, $InfoKey);
return $InfoContent;
}
}
?>
Yes, I ALSO need "return" in "else" statement because when I call the
function 2nd time the first return will return to else and then the 2nd
return will return to main code.
:D
And, I called the function 2nd time with
get_InfoContent(0, 0, $InfoKey);
and it should be
$InfoContent = get_InfoContent(0, 0, $InfoKey);
:D
