scanning <textarea> for data

[bware]

hello,

I am having a problem. I am using 4 textarea'a where users can insert their data. I want to check if two required textarea's have data and if it has data i would open database, otherwise echo an error.

This is how i check my data

$opmerking =nl2br($opmerking);
$opmerking = eregi_replace("\n","", $opmerking);
$aandachtopm =nl2br($aandachtopm);
$aandachtopm = eregi_replace("\n","", $aandachtopm); $opmerkingslijperij=nl2br($opmerkingslijperij);
$opmerkingslijperij=eregi_replace("\n","", $opmerkingslijperij);
$aandachtslijperij=nl2br($aandachtslijperij);
$aandachtslijperij=eregi_replace("\n","", $aandachtslijperij);
$i = "2";
//invoer controleren
if (strlen ($opmerking)<2)
{$error_opmerking = "0";
$i--;
}
else
{
$error_opmerking = "1";
$i++;
}
if (strlen ($opmerkingslijperij)<2)
{ $error_slijp = "0";
$i--;
}
else
{$error_slijp = "1";
$i++;
}
if (($error_slijp=="1")AND($error_opmerking == "1") AND ($i == "4")){
//open database and write

But here is the problem,

Wheter i put data in de textarea or not it wil return my $error as 1. even when it is empty.
Pleas help me

the use of eregi is redundant in your code above. you replaced all the newlines with <br> already by using nl2br, then you try to replace them again with nothing.

to keep things simple, let's call your four textarea vars $text1,$text2,$text3,and $text4.

let's assume $text1 and $text2 are your required fields.

$text1 = nl2br($text1);
$text2 = nl2br($text2);
$text3 = nl2br($text3);
$text4 = nl2br($text4);

if ( (strlen($text1)<2) || (strlen($text2)<2) )  {
echo "you did not complete required fields";
exit();
} else {
//open databases and all that fun stuff
}

hope this helps and good luck

thank you for your help and the nice pointer.
I will get my code cleanded out.

By the way, i am not so sure that the problem lied in the php. I got a bug in html.

i used text area

I opend the tag <tex..........> then hit a hard return after the tag, a tab was inserted for my own convience 'reading the code' and closed the textarea with </text......>.

Doing so i had at least 5 spaces as big as an tab in my textarea. I deleted the tab and the code worked.

thanks for the pointer about the eregireplace.

If i can help u with anything, let me know 😉
