Form Verification Always posts errors

[ambo]

Ok im trying to make it so that when some one post in a forum they cant post an empty reply so the form post to this process page which will grab the data and theres a function for uploading it Only Problem is that when you actually have text in there it says you must right something now i am useing a ready form tag which is set to false at error so it doesnt upload and that works fine except it still triggers and error when theres text

 

<?PHP 
function addforumanswer(){
$post_answer = true;
$tbl_fanswer="forum_answer"; // Table name 
// Get value of id that sent from hidden field 

$id=$_POST['id'];
// Find highest answer number. 

$sql="SELECT MAX(a_id) AS Maxa_id FROM $tbl_fanswer WHERE question_id='$id'";

$result=mysql_query($sql);

$rows=mysql_fetch_array($result);
// add + 1 to highest answer number and keep it in variable name "$Max_id". if there no answer yet set it = 1 

if ($rows) {

$Max_id = $rows['Maxa_id']+1;

}

else {

$Max_id = 1;

}
// get values that sent from form 
$a_name=$_POST['a_name'];
$a_answer=$_POST['a_answer']; 
if ($a_answer <= 0){
$post_answer = false;
echo "you Must Type Something";
}
        $a_answer = str_replace("<", "", $a_answer);
        $a_answer = str_replace(">", "", $a_answer);
        //new lines

        $a_answer = nl2br($a_answer);

$datetime=date("d/m/y H:i:s"); // create date and time 
// Insert answer 
if ($post_answer == true){

$sql2="INSERT INTO $tbl_fanswer(question_id, a_id, a_name, a_answer, a_datetime)VALUES('$id', '$Max_id', '$a_name', '$a_answer', '$datetime')";

$result2=mysql_query($sql2);
if($result2){

echo "Successful<BR>";

echo("<meta http-equiv=\"refresh\" content=\"1;url=../view_topic.php?id=$id\"/>");

$tbl_fquestion="forum_question";

$sql3="UPDATE $tbl_fquestion SET reply='$Max_id' WHERE id='$id'";

$result3=mysql_query($sql3);

}

else {

echo "ERROR";

}

mysql_close();
}

      }
?>

try the function empty();

 

if (empty($a_answer )){...}

empty() is the key but you'll probably want to negate it - you want the if() statement to continue if the post is NOT empty...

 

if (!empty($post)) {

Hmm So your saying

<?PHP
if (empty($a_answer)){

$readyform =  false;

}

[Yesideez]

If that's how you're going with it, that looks fine.
